Foldit Gamers Solve Riddle of HIV Enzyme within 3 Weeks When video gamers armed with the world's most powerful supercomputers take on science and its most vexing riddles, who wins? Sometimes, it's the gamers. Humans retain an edge over computers when complex problems require intuition and leaps of insight rather than brute calculation. "Foldit attempts to predict the structure of a protein by taking advantage of humans' puzzle-solving intuitions and having people play competitively to fold the best proteins," the company explains on its website. They've been on a tear ever since. Their latest solution has resolved a problem stumping scientists for a decade. Want to discover the next cure? Game on.
Vitamin D supplements could fight Crohn's disease A new study has found that Vitamin D, readily available in supplements or cod liver oil, can counter the effects of Crohn's disease. John White, an endocrinologist at the Research Institute of the McGill University Health Centre, led a team of scientists from McGill University and the Université de Montréal who present their findings about the inflammatory bowel disease in the Journal of Biological Chemistry. "Our data suggests, for the first time, that Vitamin D deficiency can contribute to Crohn's disease," says Dr. White, a professor in McGill's Department of Physiology, noting that people from northern countries, which receive less sunlight that is necessary for the fabrication of Vitamin D by the human body, are particularly vulnerable to Crohn's disease. Vitamin D, in its active form (1,25-dihydroxyvitamin D), is a hormone that binds to receptors in the body's cells. What Vitamin D does Dr. What's most promising about this genetic discovery, says Dr.
BOINC Online Gamers Achieve First Crowd-Sourced Redesign of Protein Obsessive gamers' hours at the computer have now topped scientists' efforts to improve a model enzyme, in what researchers say is the first crowdsourced redesign of a protein. The online game Foldit, developed by teams led by Zoran Popovic, director of the Center for Game Science, and biochemist David Baker, both at the University of Washington in Seattle, allows players to fiddle at folding proteins on their home computers in search of the best-scoring (lowest-energy) configurations. The researchers have previously reported successes by Foldit players in folding proteins, but the latest work moves into the realm of protein design, a more open-ended problem. By posing a series of puzzles to Foldit players and then testing variations on the players' best designs in the lab, researchers have created an enzyme with more than 18-fold higher activity than the original. Science by intuition "You can explore things that look crazy. Baker is now looking toward more useful targets.
New Probiotic Combats Inflammatory Bowel Disease You know the probiotics in your peach yogurt are healthful, but now it appears they may also be a powerful treatment for disease. A genetically tweaked version of a common probiotic found in yogurt and cheese appears to be an effective therapy for inflammatory bowel diseases such as Crohn's disease and ulcerative colitis. It may also prove to be useful in colon cancer, another disease triggered by inflammation. Northwestern Medicine researchers deleted a gene in the probiotic Lactobacillus acidophilus and fed the new form to mice with two different models of colitis. After 13 days of treatment, the novel probiotic strain nearly eliminated colon inflammation in the mice and halted progression of their disease by 95 percent. The study was published Jan. 31 in the Proceedings of the National Academy of Sciences. "Such gene targeting in a probiotic bacteria such as Lactobacillus acidophilus offers the possibility of a safe, drug-free treatment in the near future," he said.
ENCODE 12 Sept 2013 - New UDR ENCODE Download Method Available The UCSC Genome Browser is pleased to offer a new download protocol to use when downloading large sets of files from our download servers: UDR (UDT Enabled Rsync). UDR utilizes rsync as the transport mechanism, but sends the data over the UDT protocol, which enables huge amounts of data to be downloaded more efficiently over long distances.
