Friends and Enemies

The relationship between the United States and Britain dates to the first arrival of English settlers in the New World. A new exhibit at the Library of Congress, "John Bull and Uncle Sam: Four Centuries of British-American Relations," traces this connection from pre-Revolutionary times until now, with more than 200 rare and original treasures from the Library of Congress and the British Library.

Seven topics are examined: The Age of Exploration and Settlement, the American Revolution, War -- From Enemies to Allies, Reform Movements, Technology, Popular Culture, and Language and Literature.

Displays illustrating these themes include a proclamation by King George III declaring the colonies to be in "open rebellion;" Queen Victoria's letter to Mary Todd Lincoln after the president was assassinated; a speech by Frederick Douglass upon leaving Britain, praising racial justice he experienced there; and publicity materials from the Beatles' first album.

The exhibition, scheduled through March 4, is open Monday-Saturday, 10 a.m. to 5 p.m., at the library's Thomas Jefferson Building, 10 First St. SE. 202-707-9189.

MISFOLDED PROTEINS

What do "mad cows," people with neurodegenerative diseases and an unusual type of inheritance in yeast have in common? All seem to be experiencing the consequences of misfolded proteins. The consequences can be deadly, possibly leading to such devastating illnesses as Alzheimer's disease. When passed from one individual to another, they can produce various infectious conditions such as mad cow disease. Studies on a similar process in yeast cells indicate a new protein-based mechanism of heredity that may provide an excellent model for understanding misfolded proteins in humans.

Today at 5, Susan Lindquist of the University of Chicago is to discuss misfolded proteins in a free lecture at the National Academy of Science Auditorium, 2100 C St. NW. 202-334-2415.

WILDERNESS HEALTH

Humans have altered the vast majority of American forests, prairies and rivers -- often for the worse. Yet, in some areas, more acres of forest exist now than in 1900. Many lakes and rivers are cleaner today than 20 years ago.

So what exactly is the state of wilderness and wildlife in America today? David S. Wilcove, an ecologist at the Environmental Defense Fund, is to address this at the Smithsonian Institution's National Zoological Park tonight, 8. The talk is free, but reservations are required. Beginning at 7 p.m., Wilcove is to sign copies of his book, The Condor's Shadow: The Loss and Recovery of Wildlife in America. 202-673-4801.

FEATHERED DINOSAURS?

Scientists are becoming more convinced about the link between dinosaurs and birds, and many experts now think that feathers were widespread among juvenile meat-eating dinosaurs, possibly including Tyrannosaurus rex. Three fossil dinosaurs from China with birdlike bones and indications of feathers -- one completely new to science -- are on display at the National Geographic Society's museum, Explorers Hall, through Jan. 18. The remains, never before displayed, come from fast, bipedal meat eaters.

A LETTER FROM THE KING

The story of Anna Leonowens, a governess, and the King of Siam was popularized in a book by Margaret Landon and later by a Broadway musical and Hollywood film. King Somdetch Phra Paramendar Maha Mongkut ruled Siam (now Thailand) from 1851 to 1868 and employed Leonowens to teach his children English. The king also carried on friendly correspondence with several U.S. presidents, and one of his letters to James Buchanan, offering him elephants, is displayed at the Rotunda of the National Archives Building through the end of the month. 202-501-5000.
