Turn Off Proteins Stretch A DNA LoopBiologists have discovered that the physical manifestation of DNA loops are a consequence of a number of biochemical processes in the cell, such as the regulation of gene expression. In other words, these loops indicate the presence of enzymes or other proteins that are turned on. Now physicists at the University of California, San Diego have discovered that stretching the DNA molecule can also turn off the proteins known to cause loops in DNA.........Go to the Science-blog (Added on 12/5/2006 8:18:50 PM)
Can the Stanley Cup playoffs harm your hearing?During last year's NHL playoffs, Edmonton Oilers' fans tried to earn the title of loudest arena in the game, but new University of Alberta research shows that even a few hours of exposure to that level of noise can be harmful.

Clues to Pregnancy in Male PipefishGenetic archaeology is providing a new clue to one of the greatest gender mysteries in the fish world: how did male pregnancy evolve in a family of fish?
A gene discovered in the gulf pipefish hints that a gene already busy with kidney and liver function may have learned new tricks in the male womb, said April Harlin-Cognato, a biologist at Michigan State University, and her colleagues. Their research results, funded by the National Science........Go to the Science-blog (Added on 12/4/2006 10:03:41 PM)
Robotic Pets May Be Bad MedicineIn the face of techno-doomsday punditry, Sherry Turkle has long been a proponent of the positive. In her books, "The Second Self: Computers and the Human Spirit" and "Life on the Screen: Identity in the Age of the Internet," Turkle has explored the relationship between human and machine and found much to ponder and even praise.

Coffee and tea brewing wandsHere's a drinking concept for tea and coffee lovers that I've never seen before -- brewing wands that you use to brew your hot drink then use as a straw to sip through. Normally, you don't drink hot beverages through a straw (I vaguely recall trying to once or twice and burning my throat because I couldn't guage the temperature before it was too late). And then there's the straw melting issue with normal straws. Makes me wonder how much of the........Go to the New-technology-blog (Added on 12/4/2006 4:49:26 AM)

A Sense Of Touch For Robotic Surgery ToolsBy substituting mechanical instruments for human fingers, robotic tools give surgeons a new way to perform medical procedures with great precision in small spaces. But as the surgeon directs these tools from a computer console, an important component is lost: the sense of touch.
