Researchers Seek To Solve Mystery Of Natural HIV Control
An international, multi-institutional research consortium is seeking to discover how a few HIV-infected individuals are naturally able to suppress replication of the virus. The Elite Controller Collaborative Study, the first large-scale haplotype-mapping study in people infected with HIV, is searching for genetic factors that may explain these individuals' unique ability to control the virus without treatment, sometimes as long as 25 years after infection. [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 supposedlydelivered 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." Scientists Unravel How The Brits May Have Struck Gold In Olympic Saili
A study led by UCL (University College London) scientists has unravelled the physical mechanism behind the poorly understood weather phenomenon of coastal wind jets - which are thought to have helped the British sailing team strike gold at the Olympics.

Investigators at St. Jude Children's Research Hospital have discovered in mouse models that a gene called Six3 is one of the earliest critical regulators controlling lens development in the eye of the mammalian embryo. Studies Examine How Living Conditions Impact Reproductive Health
Life is all about tradeoffs. Recently published research has shown that during periods of intense labor and low food intake, rates of early pregnancy loss can more than double. In a second study involving men, she reports a similar relationship between reproductive fitness and external influences. Keeping It Reel — Five Pieces for Your Must-Have Angling Kit
Fly fishers dread the question: "Catch anything today?" Dazzling your interrogators with cool gear might let you dodge the question. No gadget can improve your cast, but tech can surely enhance life on the water.
 Dip ordinary paper into ink infused with nanotubes and nanowires to cr
Dip an ordinary piece of paper into ink infused with carbon nanotubes and silver nanowires, and it turns into a battery or supercapacitor. Crumple the piece of paper, and it still works. Researchers see many uses for this new way of storing electricity. Mother Deer Cannot Recognize The Calls Of Their Own Offspring But Shee
In a new study from the American Naturalist, researchers from the University of Zurich studied vocal communication between fallow deer mothers and their offspring. They found that only adult females have individually distinctive calls, meaning that fawns are able to distinguish their mother's calls from those of other females, but mothers are not able to distinguish between the calls of their own offspring and other fawns. This is in contrast to previous studies and provides a novel insight into parent-offspring recognition mechanisms. New Model Of Competitive Speciation Unifies Insights From Earlier Work
Under which circumstances is sympatric speciation possible? An answer to this long-standing question of evolutionary biology has turned out to be challenging. In particular, models for the evolution of assortative mating under frequency-dependent disruptive selection necessarily depend on a large number of ecological and genetic factors. For this reason, most previous approaches to this issue depend on individual-based simulations. However, simulation studies with only slightly different assumptions have come to wildly different conclusions, making it hard to generalize results and leading to fierce debate.
