| 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.

Birdman/Bandman: A Q&A with Shearwater's Jonathan Meiburg Listening to the music of the Austin, Tex.–band Shearwater, you get the sense that it has a bird fetish. In general, the group's lyrics are distinctly naturalist--painting pictures of wildlife and untouched ecosystems--but birds tend to appear in these narratives more often than other animals. In fact, the majority of the group's album covers are avian-themed, and the band's name itself refers to a seabird with especially long wings.Almost all of this bird business is the work of the group's singer/songwriter, Jonathan Meiburg. A tall, skinny, unfailingly polite guy with a gentle voice--both speaking and singing--he powers both Shearwater's soaring songs and its avian aesthetic. But, Meiburg is no fetishist when it comes to birds--he doesn't just walk around town with binoculars and a copy of The Sibley Guide to Birds looking for feathered friends aloft in the sky or perched in trees. Meiburg has had fully immersive experiences, tracking birds on remote islands where he--or any other human, for that matter--is a rarity. [More] rss.sciam.com |
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 |
Nevada is site of first-ever underground nuclear explosion On this day in 1957, the United States detonates a 1.7 kiloton nuclear weapon in an underground tunnel at the Nevada Test Site (NTS), a 1,375 square mile research center located 65 miles north of Las Vegas. The test, known as Rainier, was the first fully contained underground detonation and produced no radioactive fallout. A modified W-25 warhead weighing 218 pounds and measuring 25.7 inches in diameter and 17.4 inches in length was used for the test. Rainier was part of a series of 29 nuclear weapons and nuclear weapons safety tests known as Operation Plumbbob that were conducted at the NTS between May 28, 1957, and October 7, 1957.In December 1941, the U.S. government committed to building the world's first nuclear weapon when President Franklin Roosevelt authorized $2 billion in funding for what came to be known as the Manhattan Project. The first nuclear weapon test took place on July 16, 1945, at the Trinity site near Alamogordo, New Mexico. A few weeks later, on August 6, 1945, with the U.S. at war against Japan, President Harry Truman authorized the dropping of an atomic bomb named Little Boy over Hiroshima, Japan. Three days later, on August 9, a nuclear bomb called Fat Man was dropped over Nagasaki. Two hundred thousand people, according to some estimates, were killed in the attacks on the two cities and on August 15, 1945, Japan surrendered to the Allied Powers.1957's Operation Plumbbob took place at a time when the U.S. was engaged in a Cold War and nuclear arms race with the Soviet Union. In 1963, the U.S. signed the Limited Test Ban Treaty, which banned nuclear weapons testing in the atmosphere, underwater and outer space. A total of 928 tests took place at the Nevada Test Site between 1951 and 1992, when the U.S. conducted its last underground nuclear test. In 1996, the U.S signed the Comprehensive Test Ban Treaty, which prohibits nuclear detonations in all environments. history.com |
Lincoln issues Emancipation Proclamation On this day in 1862, President Abraham Lincoln issues a preliminary Emancipation Proclamation, which sets a date for the freedom of more than 3 million black slaves in the United States and recasts the Civil War as a fight against slavery.When the Civil War broke out in 1861, shortly after Lincoln's inauguration as America's 16th president, he maintained that the war was about restoring the Union and not about slavery. He avoided issuing an anti-slavery proclamation immediately, despite the urgings of abolitionists and radical Republicans, as well as his personal belief that slavery was morally repugnant. Instead, Lincoln chose to move cautiously until he could gain wide support from the public for such a measure.In July 1862, Lincoln informed his cabinet that he would issue an emancipation proclamation but that it would exempt the so-called border states, which had slaveholders but remained loyal to the Union. His cabinet persuaded him not to make the announcement until after a Union victory. Lincoln's opportunity came following the Union win at the Battle of Antietam in September 1862. On September 22, the president announced that slaves in areas still in rebellion within 100 days would be free.On January 1, 1863, Lincoln issued the final Emancipation Proclamation, which declared "that all persons held as slaves" within the rebel states "are, and henceforward shall be free." The proclamation also called for the recruitment and establishment of black military units among the Union forces. An estimated 180,000 African Americans went on to serve in the army, while another 18,000 served in the navy.After the Emancipation Proclamation, backing the Confederacy was seen as favoring slavery. It became impossible for anti-slavery nations such as Great Britain and France, who had been friendly to the Confederacy, to get involved on behalf of the South. The proclamation also unified and strengthened Lincoln's party, the Republicans, helping them stay in power for the next two decades.The proclamation was a presidential order and not a law passed by Congress, so Lincoln then pushed for an antislavery amendment to the U.S. Constitution to ensure its permanence. With the passage of the 13th Amendment in 1865, slavery was eliminated throughout America (although blacks would face another century of struggle before they truly began to gain equal rights).Lincoln's handwritten draft of the final Emancipation Proclamation was destroyed in the Chicago Fire of 1871. Today, the original official version of the document is housed in the National Archives in Washington, D.C. history.com |
