Random gene expression may drive HIV into hiding

... outcome, he explained. The researchers hope that understanding the molecular basis of HIV latency will lead to new treatments to slow or stop progression to AIDS. For example, Arkin suggested, the analysis implies that it might be effective to target the chemical modifications that Tat must undergo before it all...

Ocean climate predicts elk population in Canadian Rockies

...d about his findings because they provide a deeper understanding of the complex relationship between climate and ecosystem, and they open the door for more research in the area. The Atlantic Ocean climate has already been linked to ecosystem changes in Europe, Greenland and eastern North America, but Hebblewhite i...

The making and breaking of microtubules

...izing microtubules," says Wang. "This allows a new understanding of the mechanism of microtubule dynamic instability, opening opportunities for new experiments testing the physiological roles of these microtubule intermediates in the cell."

Researchers make headway in mystery of migraines

Scientists at the MUHC have made progress in understanding what causes migraines. The research, published in ...tely turning it off," notes Dr. Blostein. This new understanding of how genetic mutations cause migraines takes us one step closer to the development of improved tre...

UI researcher studies deafness in fruit flies, humans

...flies -- has brought scientists one step closer to understanding how such mutations result in inner-ear abnormalities and deafness in humans. "Myosin VIIA was one of the first human hereditary deafness genes to be identified. But it is not clear exactly how this molecule works in the human ear," he says. Previou...

Researchers discover stem cell 'guide' that may be key for targeting neural stem cell treatments

...ebilitating neurodegenerative diseases lies in our understanding of how new neurons are created and integrated into mature brain tissue," Zhou said. "This protein is an attractive drug target for either boosting neuron-forming processes or stem cell-based therapies for diseases like Alzheimer's and Parkinson's, or...

Improved statistical tools reveal many linked loci

...an entire genome. And unlike earlier approaches to understanding how multiple loci interact, the new technique can distinguish between a group of genes with a linked subset and a group of genes with "joint linkage," where each gene site links to another. "In some ways, it looks like you're complicating a problem ...

Mapping neuron connections in the brain

...nse of these intricate connections is essential to understanding brain function, and the task is a monumental one. Thanks to a new theoretical approach to mapping neuron connectivity published in PLoS Computational Biology by Bagrat Amirikian, a researcher at the Department of Neuroscience at the University of Mi...

Study: Well-known protein helps stem cells become secretory cells

... May 15 issue of Development, the finding improves understanding of how cells become specialized for secretion, which is a critical ability of certain glands and cell types in organisms from insects to humans. The researchers discovered that a protein called CrebA single-handedly controls the entire set of events...

Researchers develop promising new gene network analysis method

...racing human gene connections, a task critical for understanding and treating cancer and other diseases. Results appeared this week in the online edition of the Proceedings of the National Academy of Sciences. "Genes influence one another in many intricate ways," said Leon Cooper, professor of physics and neurosc...

...f Energy's Joint Genome Institute to contribute to understanding the microbiological communities living at contaminated sites," Orbach said. "Now scientists can investigate not only the 'community genome,' but also the resulting 'community proteome' for enzymes and pathways that can help clean up some of the worst...

Motor transport in bio-nano systems

... to optimize its performance. We now have a basic understanding of the behavior of single motors. These motors are dimeric proteins with two legs, which make discrete steps along the filament. Each step corresponds to a motor displacement of about 10 nanometers, comparable to the size of its legs. In one second, ...

Researchers use 3-D imaging system to unveil swimming behavior of microscopic plankton

...he ocean currents. In all those years, however, an understanding of zooplankton swimming response to ocean currents has remained elusive, mainly due to the lack of technology to track the motions of the miniscule animals in the sea. Now, an international team of scientists from Israel, the United States and Germa...
