Innovative Model Connects Circuit Theory To Wildlife Corridors
Scientists have developed a model that uses circuit theory to predict gene flow across landscapes. Their approach could give managers a better way to identify the best spots for wildlife corridors, which are crucial to protecting biodiversity. Video Voice for the Voiceless
Filmmakers using relatively cheap digital technology throw a harsh light on the plight faced by indigenous societies trying to survive the intrusion of a modern world. Jason Silverman reports from New York. NBC Universal Drops ITunes Downloads
Come December, popular NBC shows like Battlestar Galacticaand The Officewill no longer be available through the iTunes Store, after NBC (the No. 1 supplier of digital videos to iTunes) decides not to renew its contract with Apple.

Further revelations of the beauty of the ancient city of Tiberias and of its uniqueness as a Jewish center were revealed in this season's excavations there. Peptide Vaccine Fights Off Breast Tumors With Aid Of Bacteria-mimickin
With the help of immune system-stimulating molecules that mimic bacterial components, researchers have used a type of cancer vaccine to both delay and prevent breast tumors in mice. The strategy, they say, holds promise for the future use of peptide vaccines in women who are at high risk for developing breast cancer. Science Geek Gifts for All
Banish underwear from your gift-giving list this year! Your smarty-pants friends and relatives aren't as hard to buy for as you might think. The web is full of brain-gratifying gift ideas. By Kristen Philipkoski. How Fishes Conquered The Ocean
Scientists at the University of Bergen, Norway have deduced how bony fishes conquered the oceans by duplicating their yolk-producing genes and filling their eggs with the water of life -- the degradation of yolk proteins from one of the duplicated genes causes the eggs to fill with vital water and float. This is the major solution realized by extant marine teleosts that showed an unprecedented radiation during the late Cretaceous and early Paleogene Periods. Modern Humans Or Neandertals? New Evidence Sheds Light On Cave Fossils
The human fossil evidence from the Mladeč Caves in Moravia, Czech Republic, excavated more than 100 years ago, has been proven for the first time, through modern radiocarbon dating, to be the oldest cranial, dental and postcranial assemblage of early modern humans in Europe. [Scary] Pregnant woman says 'maternal instinct' helped her kill attack
FORT MITCHELL, Ky. - A pregnant woman who killed her attacker said a maternal instinct helped her fight off the woman who investigators believe was after her unborn child."I do believe that I fought harder because it was for my child,"Sarah Brady told ABC's "Good Morning America"in interviews aired Sunday and Monday. "It is a maternal instinct to protect your child to the very end."Katherine Smith, 22, died Thursday after luring Brady to her apartment to pick up a package supposedly delivered to the wrong address. When Smith pulled out a knife and attacked the pregnant woman, Brady fought back, striking Smith on the head with an ash tray and stabbing her three times with her own knife, police said. Brady, 26, said she didn't know Smith before the two met at Smith's apartment and can't be certain why Smith wanted to kill her."I really am not sure what was going through her mind,"Brady told ABC. "The only thing I thought was that she was going to kill me and my child and that is the only thing that ran through my mind." Family Of Life-extending Genes Discovered; Discovery Sheds Light On Ho
Mice, rats, worms, flies, and yeast all live longer on a low-calorie diet, which also seems to protect mammals against aging-related diseases. A gene called SIR2 is thought to control this process. Now, researchers at Harvard Medical School and UC Davis have discovered four cousins of the SIR2 gene that also extend lifespan, suggesting that the whole family of SIR2 genes is involved in controlling lifespan.
