| Seismic "Noise"--Oil Prospecting Data Could Decipher Ocean Mixing Three decades ago researchers discovered what are essentially enormous saltwater lakes in the Atlantic Ocean. These “lakes,” called meddies, are gently spinning lenses of water up to 100 kilometers across and one kilometer thick. They float a few hundred meters below the surface of the ocean. Such large, warm bodies, which turned out to come from the Mediterranean Sea, should have an impact on heat exchange in the ocean--and on the planet’s climate. But efforts to study meddies--conventionally by dropping probes that directly measure the ocean’s temperature, salinity and velocity--have proved too costly, infrequent and spread out to reveal how the meddies dissipate their heat.Now researchers have demonstrated that a tool adapted from the oil industry can take rapid, high-resolution snapshots of the meddies. The technique, first used to find oil deposits under the seafloor, exploits sound reflections. Prospectors on ships fire air guns just below the sea surface; the acoustic waves then propagate down through the seafloor and bounce back to a towed array of microphones. The timing of sound waves’ return reveals the density of the material through which they passed. [More] feeds.feedburner.com |
Bigfoot Press Conference Yields Little Evidence, Lots of Scorn PALO ALTO, CALIF.--It was perhaps the most highly touted press conference of the week, but it didn't reveal much in the way of evidence: Three bigfoot enthusiasts announced today that a series of genetic tests performed on samples taken from a carcass they claim is a Sasquatch came back as a mixture of human and opossum.In addition to the mixed DNA results, Tom Biscardi, Matthew Whitton and Rick Dyer showed the audience two blurry photos, one of a solitary figure in mixed hardwood forest and another of the mouth of what appeared to be the tongue and teeth of a primate.

Arnold Schwarzenegger becomes California governor On this day in 2003, actor Arnold Schwarzenegger is elected governor of California, the most populous state in the nation with the world's fifth-largest economy. Despite his inexperience, Schwarzenegger came out on top in the 11-week campaign to replace Gray Davis, who had earlier become the first United States governor to be recalled by the people since 1921. Schwarzenegger was one of 135 candidates on the ballot, which included career politicians, other actors, and one adult-film star.Born in Thal, Austria, on July 30, 1947, Arnold Schwarzenegger began body-building as a teenager. He won the first of four "Mr. Universe" body-building championships at the age of 20, and moved to the United States in 1968. He also went on to win a then-record seven "Mr. Olympia" championships, securing his reputation as a body-building legend, and soon began appearing in films. Schwarzenegger first attracted mainstream public attention for a Golden Globe®-winning performance in Stay Hungry (1976) and his appearance in the 1977 documentary Pumping Iron. At the same time, he was working on a B.A. at the University of Wisconsin, from which he graduated in 1979.Schwarzenegger's film career took off after his starring turn in 1982's Conan the Barbarian. In 1983, he became a U.S. citizen; the next year he made his most famous film, The Terminator, directed by James Cameron. Although his acting talent is probably aptly described as limited, Schwarzenegger went on to become one of the most sought-after action-film stars of the 1980s and early 1990s and enjoyed an extremely lucrative career. The actor's romantic life also captured the attention of the American public: he married television journalist and lifelong Democrat Maria Shriver, niece of the late President John F. Kennedy, in 1986.With his film career beginning to stagnate, Schwarzenegger, a staunch supporter of the Republican party who had long been thought to harbor political aspirations, announced his candidacy for governor of California during an appearance on The Tonight Show with Jay Leno. Aside from his well-known stint serving as chairman of the President s Council on Physical Fitness and Sports under President George H.W. Bush, Schwarzenegger had little political experience. His campaign, which featured his use of myriad one-liners well-known from his movie career, was dogged by criticism of his use of anabolic steroids, as well as allegations of sexual misconduct and racism. Still, Schwarzenegger was able to parlay his celebrity into a win, appealing to weary California voters with talk of reform. He beat his closest challenger, the Democratic lieutenant governor Cruz Bustamante, by more than 1 million votes. history.com |
Jimmy Carter wins Nobel Prize On this day in 2002, former President Jimmy Carter wins the Nobel Peace Prize "for his decades of untiring effort to find peaceful solutions to international conflicts, to advance democracy and human rights, and to promote economic and social development."Carter, a peanut farmer from Georgia, served one term as U.S. president between 1977 and 1981. One of his key achievements as president was mediating the peace talks between Israel and Egypt in 1978. The Nobel Committee had wanted to give Carter (1924- ) the prize that year for his efforts, along with Anwar Sadat and Menachim Begin, but was prevented from doing so by a technicality--he had not been nominated by the official deadline.After he left office, Carter and his wife Rosalynn created the Atlanta-based Carter Center in 1982 to advance human rights and alleviate human suffering. Since 1984, they have worked with Habitat for Humanity to build homes and raise awareness of homelessness. Among his many accomplishments, Carter has helped to fight disease and improve economic growth in developing nations and has served as an observer at numerous political elections around the world.The first Nobel Prizes--awards established by Swedish industrialist Alfred Nobel (1833-1896) in his will--were handed out in Sweden in 1901 in the fields of physics, chemistry, medicine, literature and peace. The Nobel Prize in economics was first awarded in 1969. Carter was the third U.S. president to receive the award, worth $1 million, following Theodore Roosevelt (1906) and Woodrow Wilson (1919). history.com |
