Scientists synthesize unique family of anti-cancer compounds (February 13, 2010) -- Scientists have streamlined the process for synthesizing a family of compounds with the potential to kill cancer and other diseased cells, and have found that they represent a unique category of anti-cancer agents. ... > full story
Low levels of natural antibodies behind stroke (February 13, 2010) -- The chances of suffering a stroke are linked to the presence of a certain type of antibody in the immune system, a new study from Sweden shows. The researchers hope to be able to develop a vaccine that can mobilize the body's own defense against arteriosclerosis and stroke. ... > full story
Role of protein pair in obesity regulation (February 13, 2010) -- New research implicates a new protein in obesity development and highlights a protein pair's "team effort" in regulating obesity and insulin resistance. ... > full story
Hypnosis can relieve symptoms in children with respiratory diseases (February 13, 2010) -- Hypnosis has potential therapeutic value in children with respiratory disorders for alleviating symptoms such as habit cough or unexplained sensations of difficulty breathing and for lessening a child's discomfort during medical procedures. ... > full story
Human gait adapted for efficient walking at the cost of efficient running (February 12, 2010) -- Humans, other great apes and bears are among the few animals that step first on the heel when walking, and then roll onto the ball of the foot and toes. Now, a new study shows the advantage: Compared with heel-first walking, it takes 53 percent more energy to walk on the balls of your feet, and 83 percent more energy to walk on your toes. ... > full story
Herbal medicines can be lethal, pathologist warns (February 12, 2010) -- A forensic pathologist has sounded a worldwide warning of the potential lethal dangers of herbal medicines if taken in large quantities, injected, or combined with prescription drugs. ... > full story
Cholera and related diseases: Grasping bacterial 'friending' paves the way to disrupt biofilm creation (February 12, 2010) -- Finding a biological mechanism much like an online social network, scientists have identified the bacterial protein VpsT as the master regulator in Vibrio, the cause of cholera and other enteric diseases. This discovery provides a major tool to combat enteric disease. ... > full story
How cholera bacteria becomes infectious (February 12, 2010) -- Researchers have described the structure of a protein called ToxT that controls the virulent nature of Vibrio cholerae, the bacteria that causes cholera. Buried within ToxT, the researchers were surprised to find a fatty acid that appears to inhibit ToxT, which prevents the bacteria from causing cholera. ... > full story
Self-cannibalizing cancer cells targeted (February 12, 2010) -- Scientists have embarked on a major new project to unravel the secret lives of cancer cells that go dormant and self-cannibalize to survive periods of stress. The work may help produce new cancer therapies to stem changes that render cancer cells dangerous and resistant to treatment. ... > full story

Universal DNA reader will advance faster, cheaper sequencing efforts (February 12, 2010) -- Scientists have come up with a new twist in their efforts to develop a faster and cheaper way to read the DNA genetic code. They have developed the first, versatile DNA reader that can discriminate between DNA's four core chemical components -- the key to unlocking the vital code behind human heredity and health. ... > full story
