M THEORY
Who is Edward Witten who calls this deeper understanding of strings "M theory," with M standing, he says wryly, for "mystery, magic or matrix, my three favorite words?"

Edward Witten bigger than life!

Into the Eleventh Dimension

The quest for a theory linking all matter and all forces led physicists deep into hyperspace, where they got horribly lost. But suddenly the way ahead has become clear, says superstring theorist.

Michio Kaku
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Is there a Final Theory in physics? Will we one day have a complete theory that will explain everything from subatomic particles, atoms and supernovae to the big bang? Einstein spent the last 30 years of his life in a fruitless quest for the fabled unified field theory. His approach has since been written off as futile.

In the 1980s, attention switched to superstring theory as the leading candidate for a final theory. This revolution began when physicists realised that the subatomic particles found in nature, such as electrons and quarks, may not be particles at all, but tiny vibrating strings.

Superstring theory was a stunning breakthrough. It became one of the fastest growing and most exciting areas of theoretical physics, generating a feverish outpouring of thousands of papers. Then, in the early 1990s, progress seemed to grind to a halt. People became discouraged when they failed to find the answers to two key questions: where do strings come from, and is our Universe among the many solutions of superstring theory? But now the Internet is buzzing again as papers pour in to the bulletin board at Los Alamos National laboratory in New Mexico, the official clearing house for superstring papers.

The trigger for this excitement was the discovery of "M-theory", which may answer those two vital questions about superstrings. "I may be biased on this one, but I think it is perhaps the most important development not only in string theory, but also in theoretical physics at least in the past two decades," says Harvard physicist Cumrun Vafa. M-theory led John Schwarz of Caltech, one of the founders of superstring theory, to proclaim a "second superstring revolution". And it inspired a spellbinding three-hour lecture by another leading exponent,Edward Witten of the Institute for Advanced Study at Princeton, New Jersey. The aftershocks of the breakthrough have spread to other disciplines, too. "The excitement I sense in the people in the field and the spin-offs into my own field of mathematics...have really been quite extraordinary," says Phillip Griffiths, director of the Institute for Advanced Study." I feel I've been very privileged to witness this first hand."

In one dazzling stroke, M-theory has come close to solving superstring theory's two long-standing questions , leaving many theoretical physicists (myself included) gasping at its power. M-theory, moreover, may even force string theory to change its name because, although many features of M-theory are still unknown , it does not seem to be a theory purely of strings. Other strange beasts seem to emerge, including various types of membranes. Michael Duff of Texas A&M University is already giving talks with the title " The theory formerly known as strings".

"Nature shows us only the tail of the lion. But I do not doubt that the lion belongs to it even though he cannot at once reveal himself because of his enormous size" - Albert Einstein
M-theory does not prove the final correctness of superstring theory. Not by any means. Proving or disproving its validity may take years more. But it still marks an astonishing breakthrough. Remember that some of the finest minds of this century have been stumped by the problem of creating a "Theory of Everything". Einstein summed up the problem when he said: Nature shows us only the tail of the lion. But I do not doubt that the lion belongs to it even though he cannot at once reveal himself because of his enormous size." The tail" is what we see in nature , which can be described by the four fundamental forces -gravity, electromagnetism and the strong and weak nuclear forces. The lion is the ultimate theory that will unify them in one short equation.

Today, physicists believe that the first force, gravity, can be described by Einstein's general relativity, based on the smooth warping of the fabric of space- time. This is an elegant theory that describes the macroscopic world of black holes, quasars and the big bang. But gravity has stubbornly refused to unite with the other three forces , which are described by quantum theory. Here, instead of the smooth fabric of space-time, we have the discrete world of packets of energy, or quanta.

The form of quantum theory that goes furthest in describing matter and its interactions is the Standard Model, which is based on a bizarre bestiary of particles such as quarks , leptons and bosons (see Diagram). The Standard Model may be one of the most successful theories in science, but it is also one of the ugliest. Its inadequacy is betrayed by some 19 arbitrary constants not derived by any kind of theory that have to be put in "by hand" to make the equations work.

Capturing the "lion", which unites these two great theories, would be a crowning achievement for physics. But while Einstein was first to set off on this noble hunt, tracking the footprints left by the lion, he ultimately lost the trail and wandered off into the wilderness.

Crazy departure
Today, however, physicists are following a different trail-the one leading to superstring theory. Unlike previous proposals, it has survived every blistering mathematical challenge ever hurled at it. Not surprisingly, the theory is a radical-some might say crazy-departure from the past, being based on tiny strings vibrating in 10-dimensional space-time.

"The subatomic particles we see in nature are nothing more than different resonances of the vibrating superstrings!"

To understand how going to higher dimensions can help to unify lower dimensions, think back to how the Romans used to fight wars. Without radio communications and spy planes, battles were horribly confused, raging on many fronts at the same time. That's why the Romans always leapt into "hyperspace"- the third dimension-by seizing a hill- top. From this vantage point, they were able to survey the two-dimensional battlefield as a single, unified whole.

Missing: the Standard Model works well, but still has big gaps. Could superstrings complete the picture?

Leaping to higher dimensions can also simplify the laws of nature. In 1915, Einstein changed completely our notion of gravity by leaping to the extra dimension of time. In 1919, the German mathematician Theodor Kaluza added a fifth dimension and in so doing unified space-time with Maxwell's equations for electromagnetism. This triumph was largely forgotten amid the frenzy of interest generated by quantum mechanics. Only in the 1980s did physicists return to this idea to create superstring theory.

In superstring theory, the subatomic particles we see in nature are nothing more than different resonances of the vibrating superstrings, in the same way that different musical notes emanate from the different modes of vibration of a violin string. (These strings are very small-of the order of 1035 metres.)

Likewise, the laws of physics -the forces between charged particles, for example-are the harmonies of the strings; the Universe is a symphony of vibrating strings. And when strings move in 10-dimensional space-time, they warp the space-time surrounding them in precisely the way predicted by general relativity. So strings simply and elegantly unify the quantum theory of particles and general relativity. Better still, gravity is not an inconvenient add-on. "Unlike conventional quantum field theory, string theory requires gravity," Witten has said. "I regard this fact as one of the greatest insights in science ever made."

But, of course, all this takes place in 10 dimensions. Physicists retrieve our more familiar 4-dimensional Universe by assuming that, during the big bang, 6 of the 10 dimensions curled up (or "compactified") into a tiny ball, while the remaining four expanded explosively, giving us the Universe we see. What has consumed physicists for the past ten years is the task of cataloguing the different ways in which these six dimensions can compactify. Their task has been especially difficult because mathematicians have not worked out the topology and properties of these higher-dimensional universes. The physicists have had to blaze the trail and invent entirely new areas of mathematics. These efforts have revealed millions of compactifications, each of which yields a different pattern of quarks, electrons and so on.

As we have seen, the first frustrating problem with superstring theory is that physicists do not understand where strings come from. To make matters worse, there are five string theories that unify quantum theory with relativity. This is an embarrassment of riches. Each competing theory looks quite different from the others. One, called Type 1 string theory, is based on two types of strings: "open strings", like short strands with two ends, and "closed strings", in which the ends meet to form a ring. The other four have only closed strings. Some, such as Type 2b, generate only left- handed particles, which spin in only one direction [Ref I.Asimov "Left Hand of the Electron"]. Others, such as Type 2a, have left and right-handed particles.

Today's excitement has grown from the finding that if we postulate the existence of a mysterious M-theory in 11 dimensions we can show that the five competing string theories are actually different versions of the same thing. Like a Roman general surveying the battlefield from the third dimension, physicists today stand on the hilltop of the 11th dimension and see the five superstring theories below, unified into a simple, coherent picture, representing different aspects of the same thing.

Tracking lion
The first step towards this advance came two years ago when Witten and Paul Townsend of the University of Cambridge showed that Type 2a string theory in 10 dimensions was equivalent to M-theory in 11 dimensions with one dimension curled up. Since then, all five theories have been shown to be equivalent. So at last physicists know where superstrings come from : they originate in the 11th dimension from M-theory.

M-theory also predicts that strings coexist with membranes of various dimensions. For example , a particle can be defined as a zero-brane (zero-dimensional object). A string is a one-brane, an ordinary membrane like a soap bubble is a two-brane, and so on. (Using p to represent the dimension of the object, one wag dubbed this motley collection "p-branes" ) When these p-branes vibrate or pulsate , they create new resonances , or particles, which were missed in earlier formulations of superstrings. The name "M-theory" was coined by Witten: M perhaps stands for "membrane" or the "mother of all strings", or possibly "mystery" Take your pick.

To see how this all fits together, imagine three blind men hot on the trail of Einstein's lion. Hearing it race by, they give chase and desperately grab at it. Hanging onto the tail for dear life, one feels its one-dimensional form and loudly proclaims, "It's a string. The lion is a string." The second man grabs the lion's ear. Feeling a two-dimensional surface , he calls out "No, no, the lion is really a two-brane." The third blind man, hanging on to the lion's leg, senses a three-dimensional solid, and shouts , "You're both wrong. The lion is a three- brane !" They are all right. Just as the tail, ear and leg are different parts of the same lion , the string and various p-branes appear to be different limits of M-theory. Townsend calls it "p-brane democracy".

The acid test for any theory is that it must fit the data. No matter how original and elegant superstring theory is , it will stand or fall on whether it describes the physical Universe. Either it is a Theory of Everything, as its advocates hope , or it is a theory of nothing. There is no in-between. So theoretical physicists must answer the second question : is our Universe, with its strange collection of quarks and subatomic particles, among the solutions of superstring theory? This is where it runs into an embarrassing problem, which is that physicists have been unable to find all its four-dimensional solutions. The mathematics have been fiendishly difficult-too hard for anyone to solve completely.

In general, there are two types of solutions. So far, only the first class, called "perturbative" solutions have been found. Across all branches of physics, theorists faced by an equation they cannot solve reach for well-established ways to find approximate solutions. In superstring theory, millions of these perturbative solutions have been catalogued. Each one corresponds to a different way in which to curl up 6 of the 10 dimensions. However, none of them precisely reproduces the pattern of quarks , leptons and bosons in the Standard Model, although some come close.

"M-theory solves entire classes of problems that were previously thought to be unsolvable . It even gives us valuable details of quantum effects In black holes."

So, many believe that the Standard Model may be found among the second class of solutions, the "non-perturbative" solutions. But non-perturbative solutions are generally among the most difficult of all solutions in physics. Some physicists despaired of ever finding non- perturbative solutions of superstring theory. After all, even the non-perturbative solutions of simple four-dimensional theories are completely unknown , let alone those of a complicated 10-dimensional theory.

How does M-theory help to solve this intractable problem? The answer lies in a startling tool called "duality". Simply put, in M-theory there is a duality, or simple mathematical relationship , between the perturbative and non-perturbative regions. This allows us at last to take a peek at this "forbidden zone".

To see how duality works, consider Maxwell's theory of electricity and magnetism , for example. Physicists have known for decades that if they interchange the electric field E and magnetic field B in Maxwell's equations , and also swap the electric charge e and magnetic charge g, then the equations stay the same. That is, nothing happens to Maxwell's theory if we make the dual transformation: E
Hidden theories
In fact, in Maxwell's theory, the product e times g is a constant: so small e corresponds to large g. This is the key. Suppose an equation includes a mathematical function that depends on g2 and which cannot be solved exactly. The standard mathematical trick is to approximate a solution with a perturbation expansion: g2+ g4 + g6... and so on. So long as g is less than 1, each successive term in the series is smaller than the last, and the overall value converges on a single figure.

But if g is greater than 1 then the total gets larger and larger, and the approximation fails. This is where duality comes in. If g is large, then e is less than 1. Using perturbation , we get the series e2+ e4 + e6 which gives a sensible value. Ultimately, this means that using perturbation on e can solve problems in the non-perturbative region of g.

Duality in Maxwell's theory is rather trivial. But in M-theory, we find another duality: g<1/g. This relationship, though simpler, turns out to be incredibly powerful. When I first saw it, I could hardly believe my eyes. It meant that a string theory defined for large g, which is usually impossible to describe using present-day mathematics, can be shown to be equivalent to another type of string theory for small g, which is easily described using perturbation theory.

Thus, two different string theories can be dual to each other. In the non- perturbative region of string theory was another string theory. This is how, in fact, we prove the equivalence of all five string theories. Altogether, three different types of duality called S, T and U have been discovered , which yield an intricate web of dualities linking string theories of various dimensions and types. At an incredible pace , physicists have now mapped almost all the solutions and dualities that exist in 10, 8 and 6 dimensions.

Before M-theory, finding the non-perturbative solutions in these dimensions would have been considered impossible. Now the problem is trivial. For example , let us say that two theories A and B are dual to each other in 10 dimensions. If we compactify both theories in the same way, then we obtain theories A' and B'. But now we know something new: that A' is also dual to B'. Thus, the non-perturbative behaviour of A' is given by B'. By elaborating this process, we get an almost complete understanding of the different possible universes down to 6 dimensions. Thus, M-theory solves entire classes of problems that were previously thought to be unsolvable. It even gives us valuable new details about quantum effects in black holes.

But there are many loose ends. For example, what precisely is M-theory? So far, we only know fragments of the theory (the low-energy part). We are still waiting for someone to come up with a full description of M-theory Last year, Vafa shocked physicists by announcing that there may be a 12-dimensional theory lurking out there, which he called "F-theory" (F for father).

More important, we are still far from mapping all the dualities of four dimensions. If everything works out as hoped , we should find that one of these four- dimensional universes contains the Standard Model and thus describes the known Universe. But there are millions of these solutions, so sifting through them to find the one we are after will take many years.

So will the final theory be in 10, 11 or 12 dimensions? According to Schwarz, the answer may be none of these. He feels that the true theory may not have a fixed dimensionality, and that 11 dimensions only emerge once we try to solve it. Townsend takes a similar view, saying, " The whole notion of dimensionality is an approximate one that only emerges in some semiclassical context."

So does this means that the end is in sight-that some day soon we will be able to work out the Standard Model from first principles? When I put this question to some leading physicists in this field they were still cautious. Townsend likened our present state of knowledge to the old quantum era of the Bohr atom, just before the full elucidation of quantum mechanics. "We have some fruitful pictures and some rules," he says. "But it's also clear that we don't have a complete theory."

Witten, too, believes we are on the right track. But he says we will need a few more "revolutions" like the present one to finally solve the theory. "I think there are still a couple more superstring revolutions in our future, at least," says Witten. "If we can manage one more superstring revolution a decade , I think that we will do all right." From Harvard, Vafa adds: "I hope this is the light at the end of the tunnel'. But who knows how long the tunnel is?"
Personally,I am optimistic. For the first time, we can see the outline of the lion , and it is magnificent. One day, we will hear it roar.

READING AND WRITING
In the fictional movie called "Finding Forrester," the author tells his student to first write from the heart, and then when you edit your draft, write using your head.

The movie showed that they both have a very good collection of the best writers.

This is a good example for anyone wanting to be a "good" writer.

Read the Classics, the Masterpieces of Literature, the writers who won a Pulitzer or even the Amazon.com Great American Novel list and then try your skills at writing the Great American Novel!

PRC

You can Write the Great American Novel

by James Capobianco

In this article, I would like to share with you, my thoughts on *writing*. The ability to express yourself in words. To pass on to others the knowledge and experiences you have acquired just by living. I look forward to doing just that every month in my newsletter. Maybe I can get you to look inside yourself and find these experiences and to share *your* knowledge with others.
Here's how.

Look at what the Internet is giving us. Communicating at incredible speed for next to nothing. Purchasing products and services from the comfort of our home. Allowing us to research the world for information on any subject imaginable (both good and bad I'm afraid). It also allows ANYONE to fulfill the DREAM within all of us:

to write "THE GREAT AMERICAN NOVEL!"

Or at least to give anyone the capability to create, publish and market an infoproduct for the world to read, appreciate and, hopefully buy, and make you rich.

Where will the subject matter come from? YOU..yes you! Your experiences, your knowledge, your very soul! With your own knowledge, some thought and research, I'm sure, no, I know there is a book in all of you.

No matter what kind of back ground, up-bringing, job history or life you've lived, unless you've been in a closet since birth (and even that might make a good story) you have all experienced something. Something you could share with others of similar interests.

There is something in particular we each enjoy doing and are good at. It may be your favorite hobbies such as fishing, cooking, woodworking, sewing, stamp collecting or watching television. Hmm? A good e-book might be "How I Learned to Use the Remote with Both Hands" by C. Potato. We all know something that someone else would like to know and, if properly presented, willing to pay for.

How about subjects from the real world such as job related experiences, problems you solved, a single Mom coping with life's challenges, caregiving for a loved one (with people living longer more and more people will face this challenge). Anything you've experienced that may help someone else, is subject matter.

As you can see the possibilities are endless. You can do it! But you have to be willing to devote yourself to the task. Like everything else in life, you have to make it happen.

After all, what is a book? Be it fact or fiction. It is a collection of words that has the ability to; explain how to do something, show us how to build something, entertain us, take us, by mental picture and photographic image, somewhere we've never been. Books have been around for centuries. Even with the Internet, books thrive and I'm sure always will. There is something about curling up with a good book.

However, the draw back to traditional paper books is the cost of production and distribution. Enter the Internet! Now ANYONE, with the help of their HOME computer, can write a BOOK (or electronic book, aka E-book). Almost half the homes today have computers and the number grows daily. Not only is the source for authors abundant; but so is the market for your e-book. The cost of promoting your work, though somewhat less, is still a real factor. But that too is easier on the Internet.

So what's holding you back from becoming the next, Hemingway, Steinbeck, T.S. Elliott, or T. Williams? OK! OK! I sometimes get a little carried away. But the point is:

if you live, you experience...
if you experience you gain knowledge (positive and negative)...
if you have knowledge, you have something to share...
So share your knowledge with the world (or at least those who would be interested) as you would share your knowledge with your family and friends, except do it via the Internet.

That's what I'm doing.

Ellis Island Timeline

Date Description of Ellis Island Through History

1630 The Colonial governors of New Amsterdam purchased a small, 3.5-acre mud bank in Upper New York Bay, near the New Jersey shore. The Indians called it Kioshk, or Gull Island, after the birds that were its only inhabitants. The Dutch settlers called it "Oyster Island", after the many surrounding oyster beds. The Island barely rose above the surface at high tide.

1700s During the Colonial period, the Island was known as Dyre's; later it was called Bucking. In the 1760's, after some pirates were hanged from one of the island's scrubby trees, it became known as Gibbet Island.

1776 By the time of the American Revolution, the Island was owned by Samuel Ellis, a New York merchant and owner of a small tavern on the island catering to fishermen.

1808 Samuel Ellis's heirs sold the island to New York State. The name Ellis Island stuck. Later in the year, the Federal Government bought Ellis Island for $10,000.

1812 Shortly before the War of 1812, a battery of 20 guns, a magazine and a barracks were constructed on the island.

1834 By the terms of an interstate agreement, Ellis Island and neighboring Bedloe's Island (renamed Liberty island in 1956, site of the Statue of Liberty) were declared part of New York State, even though both islands are on the New Jersey side of the main ship channel. Ellis continued to serve as an arsenal until 1890. Nearby residents of Jersey City, Manhattan and Brooklyn worried for years about explosion of the powder magazines.

1890 The States turned over control of immigration to the Federal Government. The U.S. Congress appropriated $75,000 to build the first Federal immigration station on Ellis Island. Artesian wells were dug, and landfill (from incoming ships' ballast and New York City subway tunnels) doubled the size of Ellis to over six acres. While the new immigration station was under construction, the Barge Office on the Battery on the tip of Manhattan was used for immigration reception. During 1891, there were 405,664 immigrants, or about 80% of the national total, that were processed at the Barge Office.

01 Jan 1892 The First Ellis Island Immigration Station was officially opened. The first immigrant to pass through Ellis was a "rosy-cheeked Irish girl," Annie Moore, age 15, from County Cork. She came with her two younger brothers to join their parents in New York City. That first day, three large ships were waiting to land, and 700 immigrants passed through Ellis Island. In the first year, nearly 450,000 immigrants passed through the Island.

15 Jun 1897 A fire of undisclosed origin, possibly faulty wiring, completely destroyed the Georgia pine structures on Ellis Island. No one died, but most of the immigration records dating from 1855 were destroyed. In five years, some 1.5 million immigrants had been processed. While a new, fireproof immigration station was being constructed on Ellis, processing was transferred back to the Barge Office.

17 Dec 1900 The present Main Building, an impressive, French Renaissance structure in red brick with limestone trim was open. It cost some $1.5 million and was designed to process 5,000 immigrants per day. This was scarcely big enough for the surge in immigration in the pre-World War I years. The island was continuously enlarged with landfill, remodeling, additions and new construction.

1907 This was the peak year at Ellis Island with 1,004,756 immigrants received. The all-time daily high was on April 17th of this year when a total of 11,747 immigrants were processed.

1908 The Baggage and Dormitory Building was completed and capacity of the hospital was doubled. A dining room for 1,000 at a sitting was built on the top floor of the Kitchen and Laundry Building.

30 Jul 1916 Explosions believed set by German saboteurs at nearby Black Tom Wharf in New Jersey severely damaged the Ellis Island buildings. The most notable addition included in the repairs was the new ceiling over the Great Hall, a barrel vault constructed by the Guastavino brothers.

1917 When the U.S. entered the war in Europe, Ellis Island was used to detain crews from German merchant ships anchored in New York Harbor. Suspected enemy aliens throughout America were rounded up and brought to Ellis Island.

1918-19 The U.S. Army and Navy took over most of Ellis Island for use as a way station and treatment of returning sick and wounded American servicemen. During the war, there was a sharp decline in immigration as the numbers of newcomers passing through Ellis Island decreased from 178,416 in 1915, to just 28,867 in 1918.

1921 Post-war immigration quickly revived and 560,971 immigrants passed through Ellis Island in 1921. The first Immigration Quota Law passed the U.S. Congress, adding to the administration problems at Ellis Island. It provided that the number of any European nationality entering in a given year could not exceed three percent of foreign-born persons of that nationality who lived in the U.S. in 1910. Nationality was to be determined by country of birth, and no more than 20 percent of the annual quota of any nationality could be received in any given month. The total number of immigrants admissible under the system was set at nearly 358,000, but numerous classes were exempt.

1924 The Immigration Act of 1924 further restricted immigration, changing the quota basis from the census of 1910 to that of 1890, and reducing the annual quota to some 164,000. This marked the end of mass immigration to America. The Immigration Act also provided for the examination and qualification of immigrants at U.S. consulates overseas. The main function of Ellis Island changed from that of an immigrant processing station, to a center of the assembly, detention, and deportation of aliens who had entered the U.S. illegally or had violated the terms of admittance. The buildings at Ellis Island began to fall into disuse and disrepair.

1930s Funds from the Public Works Administration permitted the landfill addition of recreation grounds on the Manhattan side of the Main Building. Works Progress Administration (WPA) labor added landscaping, new playgrounds and gardens on new landfill between Units 2 and 3. As a result of these efforts, Ellis Island reached its present 27.5 acres

1938-1945 During World War II, Ellis Island facilities were used by the Coast Guard to house and train recruits. After the U.S. entered the war in December 1941, Ellis Island was again used as a detention center for suspected enemy aliens and as a hospital for returning wounded servicemen. The detainees became so numerous that the immigration functions had to be transferred to Manhattan for lack of room on Ellis.

1946 Following the decommissioning of the Coast Guard Station, Ellis Island remained in use primarily as a detention center for aliens whose status was questioned.

1950 A brief flurry of activity occurred on Ellis Island after the passage of the Internal Security Act of 1950, which excluded arriving aliens who had been members of Communist and Fascist organizations. Remodeling and repairs were performed on the buildings to accommodate detainees who numbered as many as 1,500 at one time.

1952 As a result of the Immigration and Naturalization Act of 1952 and a liberalized detention policy, the number of detainees on Ellis Island dropped to less than 30.

Nov 1954 Ellis Island, with its 33 structures, was closed and declared excess Federal property.

1954-65 Ellis Island was under jurisdiction of the General Services Administration.

11 May 1965 President Lyndon B. Johnson issued Proclamation 3656 adding Ellis Island to the Statue of Liberty National Monument, thus placing Ellis Island under the jurisdiction of the National Park Service.

1976 Ellis Island was opened to the public for visits. Sixty-minute guided tours were limited to the Main Building. Over 50,000 visited the island in 1976.

1984 Visitation had reached 70,000 per year when the current restoration began. The non-profit Statue of Liberty-Ellis Island Foundation, Inc., chaired by Lee A. Iacocca, raised all the funds from private citizens, corporations and other groups. In collaboration with the National Park Service, it also lets contracts for the work.

Holistic Health

FRONTLINE traces the mainstreaming of alternative medicine to the halls of Congress and one U.S. senator's allergies. Viewers meet Sen. Tom Harkin (D-Iowa), who recalls complaining to a friend about his terrible allergies. The friend said he knew someone who could cure the senator's allergies using bee pollen.

"I went on this very tough regimen of taking a lot of bee pollen, sometimes as much as sixty pills a day," Harkin tells FRONTLINE. "And literally on about the tenth day, all of a sudden my allergies just left. Well, that's when I began to think, 'We've got to have somebody looking at these different approaches.'"

Harkin, the chairman of the Labor, Health and Human Services, and Education Committee, convinced Congress to allocate $2 million to the National Institutes of Health (NIH) for the study of alternative medicine. Ten years later, the National Center for Complementary and Alternative Medicine (NCCAM) has a budget of over $100 million and is funding hundreds of research projects around the nation.

In 1994, Congress passed the Dietary Supplement Health and Education Act (DSHEA), a controversial bill that limited the Food and Drug Administration's power to regulate dietary supplements at a time when the FDA was gearing up to increase its regulation of what has since become an $18 billion a year industry. Supporters claim that the bill protects the freedom of American consumers to take care of their own health by assuring access to a range of natural products.

National Center for Alternative and Complementary Medicine

Healthy Skin Healthy Body
Rewarding Experience
Celebrity and author Dr. Nicholas V. Perricone
finds his work incredibly fulfilling

If you've been watching television lately, browsing through bookstores or thumbing through national magazines, chances are you've come across the name Nicholas V. Perricone, M.D. One minute he's chatting with Diane Sawyer or Barbara Walters about the benefits of eating salmon, the next he's hitting the public television airwaves to raise millions for educational TV in programs based on his two number one New York Times best selling books The Wrinkle Cure and The Perricone Prescription

As his celebrity grows, so does his ability to improve life for millions of Americans, right where it shows-on their skin. For Dr. Perricone, who is in his mid-50's, this kind of impact has only been possible because the first life he improved was his own. "Everyone has a mission in life," he says. "And if you want to be able to carry yours out, you need a good mind and body-so, I had to be sure I had that myself before I could help anyone else."

Back in 1971, when Perricone was a 23-year-old English-literature graduate, with a stint in the Army to his credit, he found himself physically and mentally exhausted. In an effort to find out what was wrong, he underwent a complete physical exam. The doctor proclaimed him to be in perfect health despite his debilitating symptoms. Frustrated by the lack of answers, Perricone experienced first-hand, the limits of traditional medicine. This began his life-long investigation into the powerful healing benefits of nutrition. With no guidance from his own physician, he determined to figure out what was wrong and fix it himself. An avid reader, he turned his attention to books on nutrition, beginning with the works of Adele Davis, an early advocate of healthy diet. He immediately followed her recommendations to eat more protein and take nutritional supplements.

About the same time, he also accepted his first job-as program coordinator in the Connecticut office of the Muscular Dystrophy Association, a national organization that helps children with muscular dystrophy and related neuromuscular diseases. "There had recently been a breakthrough in using vitamin E to help kids with muscular dystrophy," he remembers, adding that he soon added this powerful antioxidant to his daily regimen. "I just fell into using it and it changed my life."

An exercise component soon followed and within a few months, Dr. Perricone was feeling "terrific." In fact, he was so energized that he quickly-and intensively-rekindled an interest in medical school, which had lain dormant through his military service. He began taking night classes in organic chemistry and physics to fulfill his core science requirements, while working full time during the day and applying to medical schools on his lunch breaks. "The course work was interesting," he says now. "But even at that point I knew all about nutrition and wondered about its effect on the disease process and why that was never mentioned." That oversight became his obsession.

Accepted at Michigan State medical school, Dr. Perricone soon had a chance to begin challenging traditional teachings in the classroom. He observed under the microscope that every illness, from heart disease to cancer, showed signs of inflammation. "I asked my professor why that was and he said that the body was mounting an immune response, but I didn't buy it," he says. "What does inflammation have to do with cancer? And why is it present in disease and in aging skin?

By dictating his course notes into a cassette tape that he played back around the clock, Dr. Perricone accelerated his course work, graduating in under three years, as opposed to the traditional four-year program. From Michigan he moved on to the Yale Pediatrics program, where he crossed paths with Dr. Sidney Hurwitz, an old friend who was one of the first pediatric dermatologists in the country. Dr. Hurwitz raved about dermatology, describing it as the best area in medicine from which to explore a wide range of interests. Dr. Perricone liked the idea and began a three-year residency in dermatology at the Ford Medical Center in Detroit. Once enrolled he immediately focused his attention on his earlier questions about the relationship between inflammation, disease and aging.

Because of his extensive knowledge of nutrition, he began mixing up vitamin C concoctions to test on his own sunburned skin. Using ascorbyl palmitate, a synthetic ester of vitamin C that is fat soluble (as opposed to the water-soluble ascorbic acid), he found that it penetrated the skin quickly and had a high level of healing properties that quickly made his sunburn disappear.

Dr. Perricone soon expanded his focus to alpha lipoic acid, an especially powerful antioxidant that reaches into all portions of the cell to provide protection from free radicals-the culprits that create and perpetuate inflammation. "Alpha lipoic acid boosts energy production in your cells, just as it helps the mitochondria change food to energy. As you know the higher the energy level in the cell, the more youthful you remain. The importance of alpha lipoic acid-the metabolic antioxidant-is hard to overstate."

It can also safeguard other antioxidants in the skin, such as vitamins E and C, for extra protection. Dr. Perricone found that regular topical use of alpha lipoic acid diminishes the appearance of fine lines, wrinkles and scars.

His experience in confirming these results was especially rewarding. A group of plastic surgeons in Texas performed a double-blind placebo controlled study on the effect of topical lipoic acid on scarring in young children after cleft lip palate surgery. At the end of 18 months, the children who used lipoic acid showed much less scarring and deformity than those receiving the placebo. "It was really gratifying to see the research benefit young children," he explains.

Much of this research was used to substantiate the theories he espouses in The Wrinkle Cure, which was in the top five of the New York Times bestseller list for 19 weeks-four of those at Number 1. The Perricone Prescription which came out in August 2002, spent 18 weeks on the New York Times bestseller list and four weeks in the Number 1 position. The book advocates a three-pronged approach to skin aging: diet, supplements and cosmeceuticals.

Not surprisingly Dr. Perricone follows his own advice, beginning with diet, where the principal tenet is that sugar is the enemy. "Sugar causes inflammation, inflammation causes aging," he notes. "Fifty percent of skin aging is a result of sugar. It's as bad for your skin as sun exposure. If just a drop of sugar is added to a cell culture of fibroblasts, within a minute or two we can measure a sharp rise of inflammatory chemicals in the cells.

He also shuns the type of carbohydrates, such as pasta, breads and potatoes, that rapidly raise blood sugar levels, resulting in inflammation on a cellular level that leads to wrinkles and other disease processes. Instead, he advocates salmon and green salads with olive oil for omega-3s and anti-inflammatory chemicals. Berries are also good because they are rich in antioxidants.

One of Dr. Perricone's key concerns in maintaining an anti-aging lifestyle is the control of stress. "Of all the destructive, proinflammatory and proaging forces I have observed as a physician, nothing compares to stress. Stress causes various hormonal changes in your body that rapidly alter cellular function in your vital organs." According to Dr. Perricone, the real danger of stress is that it increases the levels of cortisol in the body. In excessive amounts, the hormone cortisol can cause brain cells to die, increase blood sugar levels and negatively impact on the immune system.

He's also dedicated to exercise-but not to excess. "I take one or two days a week off," he says, "because overexercising can put you in a proinflammatory state." Dr. Perricone's workouts typically consist of a three-mile run on his home treadmill, followed by a 45-minute weight-training session every other day.

When it comes to supplements, Dr. Perricone sees himself as his own "guinea pig," because of his constant tinkering to arrive at the perfect mix. He starts each day with glutamine powder dissolved in water taken on an empty stomach for healthy maintenance of his GI track. After that comes taurine, L-carnitine, acetyl-L-carnitine, pantothenic acid and B6. He also uses N-acetyl cysteine and alpha lipoic acid to raise levels of glutathione in his cells and takes B complex and grape seed extract, DMAE and MSM, because of their powerful anti-inflammatory and antioxidant properties. "A diet high in DMAE will enable you to think more clearly, improve your memory and increase your problem-solving ability." Phosphatidylserine is on the list for cognitive enhancement, and chromium nicotinate regulates his blood sugar levels. A few times a day, he'll take zinc, extra folic acid, selenium and CoQ10, as well as stocking up on extra minerals like calcium and magnesium. Of the success of the overall regimen, he says: "Very rarely do I get sick."

Staying healthy, of course, means he can continue to carry his message to an ever-expanding audience. "After I went to medical school, I was able to apply my basic health principals to my patients and change their lives," he says. "The books and my two television specials airing nationally on the Public Broadcasting System (PBS) has helped reach even more people, allowing them to maintain their health goals. I have about 50 more research projects that I'm working on, which will help even more people. It's incredibly fulfilling." Dr. Perricone is a long-time member of the Life Extension Foundation.

Herbs - The Basics

Herbs - the primary source of medicine for people of every culture. Herbs have been mentioned in historical literature, and in the Bible. What more? The Bible tells us, "I have given you every herb bearing seed, which is upon the face of the earth, and every tree, in which is the fruit of a tree yielding seed; to you it shall be for meat." Man has used herbs to treat his illnesses for thousands of years. Herbs are safe and extremely reliable, with no side effects.

First, the term "herbs" applied to non - woody plants. Today, the word "herbs" refers to any part of any plant used for flavoring or medicine. You can find herbs in your kitchen; for example: the mustard on your table and many of the spices on your kitchen shelf come from herbs. There are many, many examples of herbal uses in your every day's life. Herbs are miracles of Mother Nature.

People always sought help through the herbs, because herbs are natural sources; unlike drugs that produce countless side effects, herbs can realign the body's defenses, helping it to heal itself with no side effects.

Herbs are natural remedies. Herbs were always the natural medicines for the human being. Writing about herbs we should mention the types of herbal medicine systems that are used today; European, Native, American, Chinese, Ayurvedic, and Western herbalist are the most prevalent systems. All of the systems treat the body as a "whole", and they each utilize the energy of herbs to "work as needed" in synergy with the natural energy in each individual. So use herbs to have natural, vital energy to do things you enjoy, to have the ability to maintain your body's natural immune system to protect you from diseases. There are many benefits of herbs. Let' s write about some of them. Herbs help cleanse and purify the body without side effects. Herbs regulate and tone the glands to function normally. Herbs are high in vitamins and minerals and other nutrients that nourish and build the body. Herbs allow the body to have extra energy to heal itself, and finally herbs promote the body's natural good bacteria.

Herbs take up substances from the earth and convert them into vitamins, minerals, carbohydrates, proteins, and fats that our bodies use for nourishment and healing. By using the whole plants or herbs, we take in all the vital ingredients they carry. Most herbs contain several active substances, one of which usually dominates and determines its choice as a remedy. Other healing aspects of the herbs should not be overlooked because they help the body to assimilate its benefits and buffer any side effects.

Herbs work synergistically, so combining them enhances each herb's properties, helping to bring greater healing to the body. For example, a good mixture to help induce sleep combines passiflora, valerian, and hops. All three herbs have relaxant properties, but passiflora specializes in aiding sleep, valerian relaxes muscle tension, and hops have a marked effect on relaxing the nervous system.

In herbology, herbs are perceived to have varying combinations of qualities and degrees of each quality, too. Herbs can be both heating and drying, or heating and moistening. It can be cooling and drying, or cooling and moistening. One herb can be very warming, while another may be just slightly warming. But both are considered heating herbs.

The way in which these qualities are assigned to plants is really very simple. Heating herbs are believed to produce warmth in the body. Generally speaking, all of the aromatic herbs, such as anise and caraway, are considered warming. Many of the bitter herbs, such as Oregon grape, are also classified as heating.

Cooling herbs, on the other hand, are those which healers believe take heat away from the body, or from some part of the body. Often, herbs that contain highly volatile oils (like wintergreen or spearmint) are categorized as cooling. Cooling herbs (borage is another example) are known as refrigerants. To get an idea of what a refrigerant is, think of a hot summer day, and then imagine eating a slice of watermelon or cucumber. These are two of the best-known refrigerant foods.

Whether an herb is classified as moistening or drying depends on its individual properties, also. An herb that has been observed to increase urination, such as bearberry, is considered drying. Any astringent herb, such as oak bark or sage, is also called drying. Usually the aromatics (like anise or caraway) are thought of as drying. But there are exceptions: fennel, for example, is regarded as moistening (it is said to increase milk in lactating women ). An herb is also considered to be moistening if it is mucilaginous or demulcent (soothing). Flax seed, marshmallow, licorice, and slippery elm are good examples of this latter type of moistening herb.

One way European herbalists began to develop a better understanding of herbal properties was to think in terms of parts of the body that they thought were influenced by each herb. That is, they began to define for each herb specific "centers of activity" in the body; For example, cayenne pepper, classified as a heating herb, was designated as affecting the circulatory system because it was observed to increase the flow of blood, especially to the capillaries near the surface of the skin. Perhaps this explains why people who live in very hot climates use hot peppers in their cooking. The peppers may actually help them to dissipate body heat by circulating it to the skin surface, where it then causes cooling as perspiration evaporates and heat radiates into the surrounding air.

Ginger is another heating herb that is assigned properties similar to those of cayenne. But ginger's center of activity is defined as lying primarily in the internal organs. In the traditional European system, it is thought to create a type of heat that stays inside the body; Ginger is therefore used by herbalists in the winter and in more northern climates. They employ it as a remedy for colds and to "strengthen" the kidneys and bladder. These differences between cayenne and ginger are due to the body's different centers of activity for each herb.

To make matters more complex, herbs are not limited to just one center of activity, either. There are many herbs that are used to treat several diverse problems at once, such as acne, constipation, headaches, lethargy, and indigestion, for example. The primary center of action for such an herb could theoretically be the liver and gall bladder, where it would be thought to cause an increase in bile secretion. The theory goes like this: Increased bile secretion improves digestion of fats and oils, which in turn improves complexion. An increase of bile will also help alleviate chronic constipation. Cleansing the colon is an important function. The accumulation of toxins in the bowels, due to poor food decomposition and elimination, contributes toward a generally toxic condition which can result in many of the symptoms listed above. Toxins in the colon are absorbed by the blood, therefore, the cleaner the colon is, the cleaner the blood will be. And the liver helps filter toxins from the blood. If the liver's rate of activity is increased, then the blood will contain fewer toxins. Many gall bladder liver entered herbs -such as Oregon grape-are described as affecting the body in all these ways. Such theories are simplistic in modem medical terms, and largely unsubstantiated by medical research. But traditional herbology does not approach healing from the perspective of laboratory analysis. It has always been based on empirical observation of individual people.

Nota bene, the ancient nations, like Egyptians, were highly skilled with herbs. The ancient text written in 1500 BC contains references to more than 700 herbal remedies, including herbs such as caraway seed, aloe, poppy, and garlic. However the Chinese have practiced herbal use for 5000 years. The Chinese are noted for their knowledge and use of ginseng. So do not be afraid to use the herbs in your kitchen. Talk about herbs and their important part in our life. There are endless other topic, supporting the beneficial effects of herbs, including herbal compounds, herbs quality, methods of preparation, herbal dosage, and nutritional content. And remember - using herbs or herbal products - means healthier life. So enjoy the herbs, aromatherapy, vitamins, and life!

16 Essential Weight Loss and Fitness Strategies

1. In the beginning, your fitness program should not be overly aggressive. One of the biggest problems people encounter when starting a fitness program is rapidly depleted motivation after only a few weeks due to an overly ambitious fitness program. Attempting to do too much too fast is worse than doing nothing at all! Because then you feel like exercise is too hard and it's just not for you.

Start out slow, maybe just shooting for 1 or 2 workouts a week. Once you have successfully added that to your normal routine, then attempt to slowly add to your fitness program. Plus, most people don't need to exercise more than 3-4 times a week. That doesn't mean you can't exercise more; it's just not necessary.

2. Always have a detailed plan! In order to reach your health and fitness goals, you must have a road map to follow. I can't stress this enough. If you are unsure of how to put together a fitness plan, or if you're uncertain of the effectiveness of the one you have, I highly recommend you consult a professional fitness trainer. With a well thought out plan you are much more likely to be successful!

3. Set realistic, attainable goals. You must have tangible, quantifiable, short and long-term goals so you can measure and assess your progress. Too many people have totally unrealistic expectations of what to expect from an exercise and nutrition program. The best way for you to understand what is realistic and attainable is to talk with a fitness professional, not to buy into the 'hype' of infomercials and diet and fitness products that are blatantly misleading.

4. Keep a journal! This is one of the most important things you can do. If you're not tracking what you're doing, how will you know what worked? There are quite a few great exercise and nutrition logs I've come across. You should keep track of all your exercise and also each day's food intake.

There's a company called NutraBiotics that makes a great 90-day journal that can be used to track strength training, cardiovascular exercise, and daily nutrition. If you would like more information on this journal, please feel free to call me at 240-731-3724.

5. You must be accountable! Set exercise appointments with yourself if you're not working with a personal fitness trainer. Use your appointment book to set aside times for exercise, just like you do for meetings or events. Don't let things get in the way. Nothing is more important than your health! If you don't have your health you can't effectively do anything. I often have mothers tell me that they can't find time to exercise because they have to take care of their children. I have 4 daughters myself, and a baby on the way, so I know exactly how hard it is. Whatever your situation is, making the commitment to exercise and your health IS possible, and very important. Plus, it sets a great example for the children!

6. Remember the benefits of exercise. Being physically fit affects every aspect of your life: you sleep better, eat better, love better, overcome stress better, work better, communicate better, and live better! Remember how good it feels to finish a workout, and how great it feels to meet your goals!

7. Exercise safely and correctly. So much time is wasted doing, at best, unproductive exercise, or at worst, dangerous exercise. Educate yourself on how to exercise correctly. The best way to do that is to hire a personal fitness trainer. It could be for just a few sessions to learn the basics, or it could be for a few months to learn everything. It's completely up to you. But statistics prove that these who understand how to exercise correctly get better, faster results. And that's what you want, right?

8. Enjoy your exercise! For example, if you hate doing strength training, try to find ways to make it more enjoyable. Circuit training might be a more fun and exciting way to fit this important part of fitness into your program. The key is you should enjoy it, and if you don't you need to look for other exercises or activities to replace whatever it is you don't enjoy.

If you don't enjoy it, how do you expect to stick with it?

9. Make time to stretch! It has so much benefit and takes very little time. So many people suffer from various aches and pains of which most can be eliminated by basic stretches! Try to spend at least 5 minutes after each workout stretching. For more information on stretching and how it eliminates aches and pains, please call 240-731-3724 to request a FREE copy of my special report "No More Back Pain."

10. Don't think you need to exercise 5 days a week! I touched on this earlier. Many people feel they're getting fat because they're not exercising. Totally not the case! Exercise is not the answer! It's all in your eating habits. However, exercise can aid in burning body fat, plus there are numerous health benefits. Think of exercise as a bonus.

How many people do you know who exercise 3-5 times per week, but still fail to meet their weight loss and fitness goals? I've met hundreds!

First look at your eating habits, such as: when you eat, what you eat, how much you eat, where you eat, and how often you eat.

11. Never skip breakfast, or any meal! If you want to maximize your fitness or fat-loss efforts you've got to eat breakfast! So many people skip breakfast, and it's the worst thing you could ever do when it comes to fat-loss. Skipping meals throws your blood sugar all out of whack and it sets you up to store your next meal as fat, almost guaranteed!

12. Eat fat to lose fat. Healthy fats are necessary to your body for numerous reasons: regulating hormonal production, improving immune function, lowering total cholesterol, and providing the basics for healthy hair, nails, and skin.

The key is to eat the right types of fats. The 'good' fats are monounsaturated and polyunsaturated fats like olive oil, canola oil, sunflower oil, safflower oil, and avocados, to name a few. The 'bad' fats are partially hydrogenated oils, and trans fats. Most processed foods contain large amounts of these bad fats. For more information on the different types of fats, please call 240-731-3724 to request a FREE copy of my Healthy Eating Guidelines.

13. Drink plenty of fresh, clean water. Yes, I know that you have probably heard this one over and over again. But there's a reason for that, it's that important! The recommended daily intake of water is 8 glasses, or 64 oz. You should even be drinking even more if you are active or exercise regularly.

And no, soda, juice, coffee, and tea DON'T count! Nearly every chemical process place in your body, takes place in water! Proper blood flow and digestion are both affected by how much water you drink, and poor blood flow and digestion can be linked to numerous health conditions.

14. Stabilize your blood sugar! If you want to burn fat and prevent your body from putting it back on, you must stabilize your blood sugar. In order to do this you need to eat small, balanced meals or snacks every 2-3 hours.

Fasting, skipping meals, and overly restrictive diets will enable you to lose weight in the short run. The weight you lose is primarily water weight and muscle tissue, and in the long run has opposite effect of what you want. When you restrict your diet, your body instinctively thinks it's being starved and shifts into a protective mode by slowing down the metabolism and storing nearly all calories as body fat. Plus, losing muscle tissue is the last thing you want to do. Muscle burns calories, even while you sleep. You should be focused on increasing, or at least maintaining muscle tissue.

15. Focus on increasing muscle tissue. As I mentioned previously, muscle burns calories, so if you want to increase your metabolism, you have to increase your muscle. The best way to do that is with progressive strength training. That doesn't mean you have to join a gym, buy expensive fitness equipment, or follow some bodybuilding workout program; it simply means you need to challenge your muscles! You can do that at home in just 15-20 minutes, 2-3 times a week.

16. Get the help of an expert.

You can get a new body in less than a month--one with more energy, a revved up metabolism to burn extra calories, and a firmer, shapelier figure that will turn heads whether you're wearing jeans or a little black dress.

The secret to dropping pounds and inches quickly is high-intensity workouts. But don't panic--you don't have to run for miles or lift 50-pound dumbbells. What's high intensity for someone who's less fit may be low for you, or vice versa.

The point is to push out of your comfort zone so you boost your calorie burn an extra 25 to 50 percent in the same amount of time--and incinerate another 75 calories over the course of the day to boot.

This firm-up plan consists of three parts: a walking workout to burn fat, body shaping with weights, and tummy-toning calisthenics. The walking workout includes four walks (easy, interval, speed, and long), and the weight workout includes three routines (basic, light, and heavy). Mixing and matching them will keep you speeding along toward fabulous results.

Firm Up Plan At-a-Glance
Here is an overview of what you'll be doing. Most days you'll combine two of the three workouts.

Monday
Easy walk
Body shaping (basic)

Tuesday
Interval walk
Tummy toning

Wednesday
Easy walk
Body shaping (light weights)

Thursday
Interval walk
Tummy toning

Friday
Easy walk
Body shaping (heavy weights)

Saturday
Speed walk
Tummy toning

Sunday
Long walk

Fat-Burning Walking Workout
Crank up your calorie burn by starting with a variety of walking routines--from moderately paced jaunts to high-speed intervals--each week. Start and finish each of your workouts with 5 minutes of slow walking to warm up and cool down. Afterwards, move on to either the Body-Shaping Workout or Tummy-Toning Workout, depending on the day of the week. On Sunday, simply enjoy the walk--you've earned it!

Easy walk (Monday, Wednesday, and Friday)
It's "easy" because you don't have to really push yourself. Just get out and walk at a good pace, as if you were 5 minutes late for an appointment.

Week 1: 30 minutes
Week 2: 35 minutes
Week 3: 40 minutes

Interval walk (Tuesday and Thursday)
Here you'll pick up the pace--and your calorie burn--for about 30 to 90 seconds before slowing down to catch your breath. During the speed interval, you should be walking so that you're breathing hard and talking in full sentences is difficult.

Week 1: 4-minute moderate pace, 30-second speed interval; do 4 times = 18 minutes total
Week 2: 4-minute moderate pace, 60-second speed interval; do 4 times = 20 minutes total
Week 3: 3-minute moderate pace, 90-second speed interval; do 4 times = 18 minutes total

Speed Walk (Saturday)
Pick an easy-to-remember route that will take about 20 minutes to complete at a fast pace. Each week, try to cover the same distance in less time.

Long Walk (Sunday)
This is your endurance workout. Walk at a pace you can comfortably sustain for the recommended time. Focus on enjoying your jaunt, not on getting out and back fast.

Week 1: 40 minutes
Week 2: 50 minutes
Week 3: 60 minutes

Body-Shaping Workout
After your walk, do the Body-Shaping moves on Monday, Wednesday, and Friday.

Lunge*

Bent-Over Row

Overhead Press

Push-Up

Reps
Basic (Monday)
Complete three sets of 10 to 12 repetitions for each exercise. Use weights heavy enough to make your last few reps challenging.

Light Weights (Wednesday)
Use lighter weights and do 3 full-rep, then 3 pulse-rep sequences three times for a total of 18 reps. For example, for the pulse reps of the overhead press, instead of bringing the weights down to shoulder height, stop at about the top of your head, then press them up three times from that position.

Heavy Weights (Friday)
Grab heavier weights and do three sets of 6 to 8 reps for each exercise.

Tummy-Toning Workout
After your walk, do the Tummy-Toning moves on Tuesday, Thursday, and Saturday.

Balance

Plank

Bridge

Twisting Crunch

For each workout, you'll do the same moves on the appropriate days, with weekly variations to make them more challenging.

Chart Your Progress
Make tracking your 21-day fitness plan easier by hanging this Fitness Log in plain sight--and using it. After every workout, simply check off the appropriate box (no, the walk times don't include warm-ups and cool-downs, but you have to do them anyway).

Genealogy In The Future With mtDNA
All we will have to do is look at a persons mtDNA to see how we are related.

NOVA: Eve the Earliest Neanderthals
Tracing Ancestry with MtDNA
By Rick Groleau

In 1987, three scientists announced in the journal Nature that they had found a common ancestor to us all, a woman who lived in Africa 200,000 years ago. She was given the name "Eve," which was great for capturing attention, though somewhat misleading, as the name at once brought to mind the biblical Eve, and with it the mistaken notion that the ancestor was the first of our species -- the woman from whom all humankind descended.

The "Eve" in question was actually the most recent common ancestor through matrilineal descent of all humans living today. That is, all people alive today can trace some of their genetic heritage through their mothers back to this one woman. The scientists hypothesized this ancient woman's existence by looking within the cells of living people and analyzing short loops of genetic code known as mitochondrial DNA, or mtDNA for short. In recent years, scientists have used mtDNA to trace the evolution and migration of human species, including when the common ancestor to modern humans and Neanderthals lived -- though there has been considerable debate over the validity and value of the findings.

In reproduction, the nuclear DNA of one parent mixes with the nuclear DNA of the other. MtDNA, on the other hand, passes on from mother to offspring unaltered.
--------------------------------------------------------------------------------

Nuclear DNA vs mitochondrial DNA
--------------------------------------------------------------------------------
When someone mentions human DNA, what do you think of? If you know a little about the topic, perhaps you think of the 46 chromosomes that inhabit the nucleus of almost every cell that comprises your body. These chromosomes hold the vast bulk of genetic information that you've inherited from your parents.

Outside the nucleus, but still within the cell, lie mitochondria. Mitochondria are tiny structures that help cells in a number of ways, including producing the energy that cells need. Each mitochondrion -- there are about 1,700 in every human cell -- includes an identical loop of DNA about 16,000 base pairs long containing 37 genes. In contrast, nuclear DNA consists of three billion base pairs and an estimated 70,000 genes. (This estimate has been revised upward several times since the announcement that the human genome had been decoded, and likely will be again.)

Inheriting mtDNA
--------------------------------------------------------------------------------
Whenever an egg cell is fertilized, nuclear chromosomes from a sperm cell enter the egg and combine with the egg's nuclear DNA, producing a mixture of both parents' genetic code. The mtDNA from the sperm cell, however, is left behind, outside of the egg cell.

So the fertilized egg contains a mixture of the father and mother's nuclear DNA and an exact copy of the mother's mtDNA, but none of the father's mtDNA. The result is that mtDNA is passed on only along the maternal line. This means that all of the mtDNA in the cells of a person's body are copies of his or her mother's mtDNA, and all of the mother's mtDNA is a copy of her mother's, and so on. No matter how far back you go, mtDNA is always inherited only from the mother.

If you went back six generations in your own family tree, you'd see that your nuclear DNA is inherited from 32 men and 32 women[1]. Your mtDNA, on the other hand, would have come from only one of those 32 women.

See the difference between mtDNA and nuclear DNA ancestry with this interactive family tree.

Defining mitochondrial ancestors
--------------------------------------------------------------------------------
Let's get back to "Eve." The ancestor referred to in the 1987 Nature article can be more precisely stated as "the most recent common ancestor through matrilineal descent of all humans living today." In other words, she is the most recent person from whom everyone now living on Earth has inherited his or her mtDNA. This certainly does not mean that she is the ancestral mother of all who came after her; during her time and even before her time there were many women and men who contributed to the nuclear genes we now carry. (To see how this can be, check out Tracing Ancestry.) It also does not mean that the mtDNA originated with this "Eve"; she and her contemporaries also had their own "most recent common ancestor though matrilineal descent," a woman who lived even further into the past who passed on her mtDNA to everyone living during "Eve's" time. (We get our mtDNA from that same, older ancestor. She's just not, to us, the most recent common ancestor.)

So what about all of the mtDNA of the other women who lived during "Eve's" time? What happened to it? Simply this: Somewhere between now and then, they had female descendants who had only sons (or no children). When this happened, the passing on of their mtDNA halted.

Finding mitochondrial ancestors
--------------------------------------------------------------------------------
Even though everyone on Earth living today has inherited his or her mtDNA from one person who lived long ago, our mtDNA is not exactly alike. Random mutations have altered the genetic code over the millennia. But these mutations are organized, in a way. For example, let's say that 10,000 years after the most recent common ancestor, one of the mtDNA branches experienced a mutation. From that point on, that line of mtDNA would include that alteration. Another branch might experience a mutation in a different location. This alteration would also be passed on. What we would eventually end up with are some descendants who have mtDNA that is exactly or very much like that of some people's, somewhat like that of others, and less like that of yet others. By looking at the similarities and differences of the mtDNA of all of these individuals, researchers could try to reconstruct where the branching took place.

This is what some researchers have done. For the original 1987 Nature article, the three authors (Rebecca Cann, Mark Stoneking, and Allan Wilson) looked at the mtDNA of 147 people from continents around the world (though for Africans, they relied on African Americans[2]). Later, with the help of a computer program, they put together a sort of family tree, grouping those with the most similar DNA together, then grouping the groups, and then grouping the groups of groups. The tree they ended up with showed that one of the two primary branches consisted only of African mtDNA and that the other branch consisted of mtDNA from all over the world, including Africa. From this, they inferred that the most recent common mtDNA ancestor was an African woman.[3]

Dating mitochondrial ancestors
--------------------------------------------------------------------------------
The three researchers went even further -- they estimated the age of the ancestor. To get the estimate, they made the assumption that the random mutations occurred at a steady rate. And since they now had an idea of how much the mtDNA had changed from the ancestor's, all they needed was the mutation rate to determine the age of the ancestor. For instance, if they took the mutation rate to be one in every 1,000 years and knew that there was a difference of 10 mutations between the mtDNA of people living today and the mtDNA of an ancestor who lived long ago, then they could infer that the ancestor lived 10,000 years ago.

Cann, Stoneking, and Wilson estimated the mutation rate by looking at the mtDNA of groups of people whose ancestors migrated to areas at known times. One group was Australian aborigines, whose ancestors moved to the island-continent a then-calculated 30,000 years ago.[4] Since the three then knew how long it took for that group's mtDNA to diverge as well as how much it diverged, they determined the mutation rate. Using this rate, they determined that the most recent common ancestor lived 140,000 to 290,000 years ago (which they roughly averaged to 200,000 years ago). That was back in 1987. Since then, researchers have updated the estimate to 120,000 to 150,000 years ago. However, the margin for error for this estimate and the previous one are significant -- when all of the variables are taken into account, the current range is more like 50,000 to 500,000.

Mitochondrial DNA is extracted from the bones of Neanderthals and compared to the mtDNA of living Homo sapiens.
--------------------------------------------------------------------------------

Neanderthals and mtDNA
--------------------------------------------------------------------------------
Finding out about our most recent common ancestor relies solely on inferences from the mtDNA of people living today. What if we could actually compare our mtDNA with mtDNA of a distant ancestor? This, in fact, has been done, with mtDNA from the bones of Neanderthals. Comparing mtDNA of these Neanderthals to mtDNA of living people from various continents, researchers have found that the Neanderthals' mtDNA is not more closely related to that of people from any one continent over another. This was an unwelcome finding for anthropologists who believe that there was some interbreeding between Neanderthals and early modern humans living in Europe (which might have helped to explain why modern Europeans possess some Neanderthal-like features); these particular anthropologists instead would have expected the Neanderthals' mtDNA to be more similar to that of modern Europeans than to that of other peoples. Moreover, the researchers determined that the common ancestor to Neanderthals and modern Homo sapiens lived as long as 500,000 years ago, well before the most recent common mtDNA ancestor of modern humans. This suggests (though it does not prove) that Neanderthals went extinct without contributing to the gene pool of any modern humans.

Final note
--------------------------------------------------------------------------------
There are many variables that can affect the mutation rate of mtDNA, including even the possibility that mtDNA is not always inherited strictly through maternal lines. In fact, recent studies show that paternal mtDNA can on rare occasions enter an egg during fertilization and alter the maternal mtDNA through recombination. Such recombination would drastically affect the mutation rate and throw off date estimates.

Not surprisingly, there is currently a heated debate over the value of "mitochondrial Eve" -- especially between history-hunting geneticists and some fossil-finding paleoanthropologists. According to these anthropologists, even if we could accurately gauge the age of the ancestor, that knowledge is meaningless because all she really is is the woman whose mtDNA did not die out due to random lineage extinctions. Furthermore, her status as the most recent common ancestor doesn't mean that she and her contemporaries were any different from their ancestors. (Remember, she and all of her contemporaries had their own mitochondrial Eve.)

Perhaps the most valuable finding regarding the "most recent common ancestor" is that she probably lived in Africa -- a finding that supports the most popular theories about the worldwide spread of hominids.

Notes
--------------------------------------------------------------------------------
1. Unless two or more of those 64 married each other and bore children from which you are descended. For example, your great-great-grandfather on your mother's side might have married and had children with your great-great-grandmother on your father's side. In that case, the number of your ancestors in this example would drop to 63.

2. Although the original study was criticized for using African Americans instead of native Africans, a subsequent study in which the researchers used mtDNA from native Africans came up with similar results.

3. Other researchers later showed that the computer program could come up with other variations of the tree, some of which did not place an African at the root of the tree. This study, then, cannot be viewed as definitive proof that the ancestor lived in Africa. However, it does still suggest that humans originated in Africa, a hypothesis that other, more recent studies support.

4. The date for the migration to Australia is now estimated to be 50,000 to 60,000 years ago.
