Amazon River Reversed Flow
Ask any South American dinosaur which way the Amazon River flows and she would have told you east-to-west, the opposite of today. That's the surprising conclusion of researchers studying ancient mineral grains buried in the Amazon Basin. White Collar Proteins Help Fungi Do It In The Dark
Two genes controlling light responses - BWC1 and BWC2 - were identified and shown to regulate development and virulence of the fungal pathogen Cryptococcus neoformans. Urban Experience in Chicago: Hull-House and Its Neighborhoods, 1889-19

Trace amounts of genetically engineered rice was present in two varieties of rice, Cheniere and CL131. No short- or medium-grain rice varieties tested positive for either GE strain investigated. The exact mechanism for introduction of the GE material could not be determined in either instance. Jump-starting T Cells In Skin Cancer
Advanced melanoma, the most deadly form of skin cancer, can be successfully treated in some cases by vaccinating patients with tumor proteins. How these vaccines work and why they are only effective in some patients remains unclear. Pierre Coulie and colleagues now show, in two articles in the January 17 issue of the Journal of Experimental Medicine, that these vaccines work by increasing the number of immune cells called killer T cells that can attack the tumor. In an unexpected finding, however, they discovered that that these cells mostly recognize tumor proteins that were not contained in the vaccine. 3-D Imaging Of Motor Proteins Provides New Insights To Molecular Mecha
Scientists from the Burnham Institute for Medical Research and the University of Vermont have captured the first 3-dimensional (3D) atomic-resolution images of the motor protein myosin V as it "walks"along other proteins, revealing new structural insights that advance the current model of protein motility and muscle contraction. The culmination of four years of work, this collaboration among biochemists and structural biologists was selected as the cover story for the September issue of the scientific journal Molecular Cell. [Absurd] Man Says He Was Blinded 4 Times in One Eye
In 1985, Brian Calen claimed he was blinded in the right eye in a cruise ship accident. Seven years later, he said a ship's telescope blinded him again. Then, he said, he was blinded on two more trips —- by a champagne bottle and a flying disc. Study Finds New Type Of Silicone Implant Offers More Natural Looking B
A new type of silicone breast implant may offer breast augmentation and reconstruction patients more natural looking breasts with a low complication rate, according to a study in Plastic and Reconstructive Surgery, the official medical journal of the American Society of Plastic Surgeons (ASPS). The new gel implants will be the next type of silicone implant produced by manufacturers if the FDA approves the devices to be marketed and sold in the United States. Bram Cohen on BitTorrent's Future
Rumor has it he's leaving the company he co-founded -- just as BitTorrent lands big distribution deals with Hollywood. Can the rumors about Bram Cohen be true? What's in store for online file-sharing? Michael Calore snags an exclusive interview. Cloning Techniques Produce FDA-approved Antibiotic
The successful synthesis of an antibiotic in a non-native host has provided a team of researchers at the University of Illinois at Urbana-Champaign with the potential for developing new treatments for bacterial infections.
