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
Single-step technique produces both p-type and n-type doping for future graphene devices (February 13, 2010) -- A simple one-step process that produces both n-type and p-type doping of large-area graphene surfaces could facilitate use of the promising material for future electronic devices. The doping technique can also be used to increase conductivity in graphene nanoribbons used for interconnects. ... > 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
High-tech applications envisioned for 'multiferroic' crystals (February 13, 2010) -- Scientists have had surprising results involving an unusual family of crystalline minerals. Their findings could lay the groundwork for future researchers seeking to develop a new generation of computer chips and other information-storage devices that can hold vast amounts of data and be strongly encrypted for security purposes. ... > 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
Science used to decode the secrets of Olympic skeleton sliding (February 12, 2010) -- Olympic skeleton athletes will hit the ice next month in Vancouver, where one-hundredths of a second can dictate the difference between victory and defeat. Using state-of-the-art flow measurements, engineers are employing science and technology to help the US skeleton team trim track times and gain an edge over other sliders. ... > 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
Dramatic changes in agriculture needed as world warms and grows (February 12, 2010) -- Scientists are urging dramatically changed ideas about sustainable agriculture to prevent a major starvation catastrophe by the end of this century among more than 3 billion people who live in the tropics. ... > full story
Spitzer goes to the Olympics: Art professor to show space telescope-inspired work at Winter Olympics digital art exhibition (February 12, 2010) -- Artwork inspired by NASA's Spitzer Space Telescope is making an appearance at this year's Winter Olympics in Vancouver, British Columbia. No, it's not battling other telescopes for the "gold," but its observations are now on display as part of the Vancouver 2010 Cultural Olympiad Festival. ... > full story
