Hutterites Are Model Gene Community
[The following is an exact transcript of this podcast.]You may have heard of genetic research being done in Iceland. It’s a rich venue, because Icelanders have a limited gene pool and highly detailed genealogical records. Well, it looks like we have our own version of Icelanders here in the U.S. They’re called the Hutterites, and they live in rural South Dakota. Researchers from the University of Chicago and Northwestern have been studying the Hutterites for decades. Almost 1,300 members of the community emigrated from Germany to South Dakota in 1874. Today they number in the tens of thousands. They live similar communal farming lifestyles, so they experience common environmental influences. [More] rss.sciam.com |
Texas Archaeological Dig Challenges Assumptions about First Americans
FLORENCE, TEX.--"Look at that--isn't it gorgeous?" Sandy Peck asks as she rinses dirt from a flaked stone about the length and width of a pinky finger. Peck runs a hose over soil on a fine-mesh screen, prodding at stubborn clods of clay with a muddy glove. "Look, there's another one."View Slide Show of the Dig [More] rss.sciam.com |
The Science of Saving Art: Can Microbes Protect Masterpieces?
Art conservationists, curators and scientists from around the world are gathering this week in Caracas, Venezuela, to address some of the burgeoning concerns about the state of art and artifact collections around the world–particularly those in tropical climes, which are under assault from mold, fungus and insects. At the Forum on Cultural Heritage Conservation, researchers are highlighting the many macro-abilities of microorganisms in the art world, which range from detecting whether a gallery's air quality might be harmful to delicate objects d'arts to actually cleaning a dirty piece with helpful bacteria.

John Adams appointed to negotiate peace terms with British
On this day in 1779, the Continental Congress appoints John Adams to travel to France as minister plenipotentiary in charge of negotiating treaties of peace and commerce with Great Britain during the Revolutionary War.Adams had traveled to Paris in 1778 to negotiate an alliance with France, but had been unceremoniously dismissed when Congress chose Benjamin Franklin as sole commissioner. Soon after returning to Massachusetts in mid-1779, Adams was elected as a delegate to the state convention to draw up a new constitution; he was involved in these duties when he learned of his new diplomatic commission. Accompanied by his young sons John Quincy and Charles, Adams sailed for Europe that November aboard the French ship Sensible, which sprang a leak early in the voyage and missed its original destination (Brest), instead landing at El Ferrol, in northwestern Spain. After an arduous journey by mule train across the Pyrenees and into France, Adams and his group reached Paris in early February 1780.While in Paris, Adams wrote to Congress almost daily (sometimes several letters a day) sharing news about British politics, British and French naval activities and his general perspective on European affairs. Conditions were unfavorable for peace at the time, as the war was going badly for the Continental Army, and the blunt and sometimes confrontational Adams clashed with the French government, especially the powerful Foreign Minister Charles Gravier, Comte de Vergennes. In mid-June, Adams began a correspondence with Vergennes in which he pushed for French naval assistance, antagonizing both Vergennes and Franklin, who brought the matter to the attention of Congress.By that time, Adams had departed France for Holland, where he was attempting to negotiate a loan from the Dutch. Before the end of the year, he was named American minister to the Netherlands, replacing Henry Laurens, who was captured at sea by the British. In June 1781, capitulating to pressure from Vergennes and other French diplomats, Congress acted to revoke Adams' sole powers as peacemaker with Britain, appointing Franklin, Thomas Jefferson, John Jay and Laurens to negotiate alongside him.The tide of the war was turning in America's favor, and Adams returned to Paris in October 1782 to take up his part in the peace negotiations. As Jefferson didn't travel to Europe and Laurens was in failing health after his release from the Tower of London, it was left to Adams, Jay and Franklin to represent American interests. Adams and Jay both distrusted the French government (in contrast with Franklin), but their differences of opinion and diplomatic styles allowed the team to negotiate favorable terms in the Peace of Paris (1783). The following year, Jefferson arrived to take Adams' place as American minister to France, forming a lifelong bond with Adams and his family before the latter left to take up his new post as American ambassador to London and continue his distinguished record of foreign service on behalf of the new nation. history.com |
Reporter Judith Miller released from prison
On this day in 2005, New York Times reporter Judith Miller is released from a federal detention center in Alexandria, Virginia, after agreeing to testify in the investigation into the leaking of the identity of covert CIA officer Valerie Plame. Miller had been behind bars since July 6, 2005, for refusing to reveal a confidential source and testify before a grand jury that was looking into the so-called Plame Affair. She decided to testify after the source she had been protecting, I. Lewis "Scooter" Libby, Vice President Dick Cheney's chief of staff, signed a waiver giving her permission to speak.The Plame Affair dates back to a July 6, 2003 op-ed piece for the New York Times written by former U.S. diplomat Joseph Wilson, Plame's husband. In it, Wilson questioned the Bush Administration's reasons for going to war in Iraq. Later that month, on July 14, undercover agent Valerie Plame's identity was revealed in a newspaper column by Robert Novak. Wilson's claim that the disclosure was retaliation by the White House for his op-ed piece sparked an investigation in December 2003 led by special prosecutor Patrick Fitzgerald. A 1982 law made it illegal to reveal information about a covert agent to anyone not authorized to receive such classified information.Fitzgerald interviewed President George W. Bush, Vice President Cheney and other top administration officials, along with various journalists. Although Miller hadn't written an article about Plame, she did meet with Libby shortly after Wilson's op-ed piece was published and Fitzgerald believed Miller had information that was relevant to his investigation.After 85 days in jail, Miller was released and testified before a grand jury that prior to the Novak column, she had several discussions with Scooter Libby in which he talked about Plame. On November 9 of that same year, Miller announced her retirement from the Times after a 28-year career with the newspaper.On March 6, 2007, Scooter Libby was convicted of obstruction of justice, perjury and making false statements to federal investigators in the Plame investigation. In June, he was sentenced to 30 months in federal prison and fined $250,000. However, one month later, on July 2, President George W. Bush commuted Libby's prison term before the ex-White House aide served any time. history.com |
