New bioinformatics technique for systematically analyzing key regions in DNA that help control gene activity

Scientists at Lawrence Livermore National Laboratory (LLNL) and the Linnaeus Centre for Bioinformatics (LCB) at Uppsala University in Sweden have developed a new bioinformatics technique for systematically analyzing key regions in DNA that help control gene activity. The cooperative efforts were headed by Krzysztof Fidelis in the United States and by Jan Komorowski in Sweden. Understanding...

Cancer cells suppress large regions of DNA by a reversible process that can be tackled

Cancer researchers at Sydney's Garvan Institute, in collaboration with Spanish scientists, have formulated a new concept for how cancer cells can escape normal growth controls, which may have far-reaching implications for the new generation of cancer therapies. They have found large regions of DNA are 'switched off' in colon cancer. Lead researcher Associate Professor Sue Clark, of the Gar...

Biologists find regions of rice domestication

Biologists from Washington University in St. Louis and their collaborators from Taiwan have examined the DNA sequence family trees of rice varieties and have determined that the crop was domesticated independently at least twice in various Asian locales. Jason Londo, Washington University in Arts & Sciences biology doctoral candidate, and his adviser, Barbara A. Schaal, Ph.D., Washingt...

Brain regions do not communicate efficiently in adults with autism

A novel look at the brains of adults with autism has provided new evidence that various brain regions of people with the developmental disorder may not communicate with each other as efficiently as they do in other people. Researchers from the University of Washington's Autism Center will report today at the annual meeting of the Society for Neuroscience on the first study that measures ne...

Newborn brains grow vision and movement regions first

The regions of the brain that control vision and other sensory information grow dramatically in the first few months following birth, while the area that controls abstract thought experiences very little growth during the same period, University of North Carolina at Chapel Hill researchers have found. The researchers discovered that the back regions of the brain, which control vision and s...

Imaging pinpoints brain regions that 'see the future'

Human memory, the ability to recall vivid mental images of past experiences, has been studied extensively for more than a hundred years. But until recently, there's been surprisingly little research into cognitive processes underlying another form of mental time travel -- the ability to clearly imagine or "see" oneself participating in a future event. Now, researchers from Washington Univ...
