| Neandertal Mitochondrial DNA Sequenced [The following is an exact transcript of this podcast.]Neandertals were our closest relatives. And now we know a lot more about them. Because researchers have for the first time sequenced a complete Neandertal genome--that of their mitochondrial DNA. The study appears in the August 8th issue of the journal Cell.

Do Mythic Creatures Exist? Show Me the Body Editor's Note: This story was originally published in the May 2003 issue of Scientific American.The world lost the creators of two of its most celebrated biohoaxes recently: Douglas Herrick, father of the risibly ridiculous jackalope (half jackrabbit, half antelope), and Ray L. Wallace, paternal guardian of the less absurd Bigfoot. The jackalope enjoins laughter in response to such peripheral hokum as hunting licenses sold only to those whose IQs range between 50 and 72, bottles of the rare but rich jackalope milk, and additional evolutionary hybrids such as the jackapanda. Bigfoot, on the other hand, while occasionally eliciting an acerbic snicker, enjoys greater plausibility for a simple evolutionary reason: large hirsute apes currently roam the forests of Africa, and at least one species of a giant ape--Gigantopithecus-- flourished some hundreds of thousands of years ago alongside our ancestors.

Why Everyone Should Learn the Theory of Evolution Charles Darwin did not think of himself as a genius. “I have no great quickness of apprehension or wit which is so remarkable in some clever men ...” he remarked in one passage of his autobiography. Fortunately for the rest of us, he was profoundly wrong in his assessment. So on February 12 the world will mark the bicentennial birthday of a scientist who holds a rightful place alongside Galileo, Copernicus, Newton and Einstein.Darwin’s genius--and, yes, genius is the right word--is manifest in the way his theory of evolution can tie together disparate biological facts into a single unifying framework. Evolutionary geneticist Theodosius Dobzhansky’s oft-cited quotation bears repeating here: “Nothing in biology makes sense, except in the light of evolution.” [More] rss.sciam.com |
King triumphs in Battle of Sexes On this day in 1973, in a highly publicized "Battle of the Sexes" tennis match, top women's player Billie Jean King, 29, beats Bobby Riggs, 55, a former No. 1 ranked men's player. Riggs (1918-1995), a self-proclaimed male chauvinist, had boasted that women were inferior, that they couldn't handle the pressure of the game and that even at his age he could beat any female player. The match was a huge media event, witnessed in person by over 30,000 spectators at the Houston Astrodome and by another 50 million TV viewers worldwide. King made a Cleopatra-style entrance on a gold litter carried by men dressed as ancient slaves, while Riggs arrived in a rickshaw pulled by female models. Legendary sportscaster Howard Cosell called the match, in which King beat Riggs 6-4, 6-3, 6-3. King's achievement not only helped legitimize women's professional tennis and female athletes, but it was seen as a victory for women's rights in general.King was born Billie Jean Moffitt on November 22, 1943, in Long Beach, California. Growing up, she was a star softball player before her parents encouraged her to try tennis, which was considered more ladylike. She excelled at the sport and in 1961, at age 17, during her first outing to Wimbledon, she won the women's doubles title. King would rack up a total of 20 Wimbledon victories, in singles, doubles and mixed doubles, over the course of her trailblazing career. In 1971, she became the first female athlete to earn more than $100,000 in prize money in a single season. However, significant pay disparities still existed between men and women athletes and King lobbied hard for change. In 1973, the U.S. Open became the first major tennis tournament to hand out the same amount of prize money to winners of both sexes.In 1972, King became the first woman to be chosen Sports Illustrated's "Sportsperson of the Year" and in 1973, she became the first president of the Women's Tennis Association. King also established a sports foundation and magazine for women and a team tennis league. In 1974, as a coach of the Philadelphia Freedoms, one of the teams in the league, she became the first woman to head up a professional co-ed team.The "mother of modern sports" retired from tennis with 39 Grand Slam career titles. She remained active as a coach, commentator and advocate for women's sports and other causes. In 2006, the USTA National Tennis Center, home of the U.S. Open, was renamed in King's honor. During the dedication ceremony, tennis great John McEnroe called King "the single most important person in the history of women's sports." history.com |
The First Supreme Court The Judiciary Act of 1789 is passed by Congress and signed by President George Washington, establishing the Supreme Court of the United States as a tribunal made up of six justices who were to serve on the court until death or retirement. That day, President Washington nominated John Jay to preside as chief justice, and John Rutledge, William Cushing, John Blair, Robert Harrison, and James Wilson to be associate justices. On September 26, all six appointments were confirmed by the U.S. Senate.The U.S. Supreme Court was established by Article 3 of the U.S. Constitution. The Constitution granted the Supreme Court ultimate jurisdiction over all laws, especially those in which their constitutionality was at issue. The high court was also designated to oversee cases concerning treaties of the United States, foreign diplomats, admiralty practice, and maritime jurisdiction. On February 1, 1790, the first session of the U.S. Supreme Court was held in New York City's Royal Exchange Building.The U.S. Supreme Court grew into the most important judicial body in the world in terms of its central place in the American political order. According to the Constitution, the size of the court is set by Congress, and the number of justices varied during the 19th century before stabilizing in 1869 at nine. In times of constitutional crisis, the nation's highest court has always played a definitive role in resolving, for better or worse, the great issues of the time. history.com |
