Neutral Evolution Has Helped Shape Our Genome
Johns Hopkins researchers have added to the growing mound of evidence that many of the genetic bits and pieces that drive evolutionary changes do not confer any advantages or disadvantages to humans or other animals. They have demonstrated that one of the major architectural markers of the human genome, DNA repeat elements that make up over 40 percent of our genome, rose to prominence without offering any benefits to the organism it inhabits. What's Been Causing Your Knee To Ache? Smurfs!
A new clinical trial seeks to predict who is most likely to experience osteoarthritis, and to test whether an experimental treatment can prevent it altogether. Physicians are setting their sights on people who sustain a knee injury, seeking to understand why nearly half of them will later go on to develop osteoarthritis, a debilitating condition that causes pain and disability in more than 20 million Americans each year. How Does Your Brain Respond When You Think About Gambling Or Taking Ri
Should you leave your comfortable job for one that pays better but is less secure? Should you have a surgery that is likely to extend your life but poses some risk that you will not survive the operation? Should you invest in a risky startup company whose stock may soar even though you could lose your entire investment? In the Jan. 26 issue of the journal Science, UCLA psychologists present the first neuroscience research comparing how our brains evaluate the possibility of gaining versus losing when making risky decisions. Sex Toy Expo Fun, Not Novel
The annual Adult Novelty Expo could use some newfangled toys, but the sex-positive atmosphere is stimulating. Commentary by Regina Lynn. [Odd] A Romanian couple has named their son Yahoo as a sign of gratitu

Researcher Studies Sleep Deprivation's Effect On Decisions
Everyone needs sleep, but temporary periods with no sleep can be a reality of military operations. To get answers on sleep questions for the military as well as civilians, for nearly four years Dr. Sean Drummond, a Department of Defense-funded researcher, has studied the effects of sleep deprivation on the brain, namely in decision making, as well as how long it takes to recover from periods of no sleep. Elephants Tell Human Friends From Foes By Scent And Clothing Color
Elephants are remarkably perceptive when it comes to recognizing specific ethnic groups of people that vary in the degree of danger they are likely to pose. Elephants in Kenya reacted with greater fear when they detected the scent of garments previously worn by Maasai warriors than by Kamba men, the researchers reported. NASA's Deep Impact Spacecraft On Its Way To Encounter With Comet Tempe
Launched from Cape Canaveral Air Force Station on Wednesday, the Deep Impact spacecraft entered a state called safe mode soon after separation from the launch vehicle. When a spacecraft enters safe mode, all but essential spacecraft systems are turned off until it receives new commands from mission control. When Deep Impact separated from the launch vehicle, the spacecraft computer detected higher than expected temperatures in the propulsion system. Scientists See With X-rays How Bones Resist Strain Thanks To Their Nan
Scientists from Max Planck Institute (Germany) and the ESRF have just discovered the way deformation at the nanoscale takes place in a bone by studying it with the synchrotron X-rays. This study explains the enormous stability and deformability of bones. The hierarchical structure of bones makes them able to sustain large strains without breaking, despite being made of essentially rigid units at the molecular level. Navdanya: Seed Sovereignty
Introduction to the seed-related activities of this organization (based in New Delhi, India) founded by scientist and environmentalist Dr. Vandana Shiva.
