New study explains process leading to many proteins from one gene
..., and he said the new findings could go a long way toward understanding the genetic nature of how cancers start and progress. "With this new understanding, we can now predict all genes that can re-arrange in this way and even predict which might splice improperly, resulting in disease," he said.

"Many of those patients can consider clinical trial options that they may otherwise have overlooked or not feel justified. "If you identify the ones who are...Brain-injury rehabilitation depends on acetylcholine circuitry
...The present study makes a significant contribution toward this goal by identifying the basal forebrain cholinergic system as an essential substrate in mediating cortical plasticity and functional recovery following focal cortical injury."

...to other neurons in the brain is an important step toward understanding how and why we sleep. Mapping the neurons to which orexin neurons send signals has been relatively easy, Dr. Yanagisawa said, but determining which neurons send signals to orexin neurons has been a challenge.

...me neurons in mice and humans take the first steps toward producing insulin. In insects such as fruit flies, the cells that produce insulin and regulate blood sugar are, in fact, neurons. Taken together, this evidence suggested to Kim that neural stem cells may be able to produce insulin. Despite Kim's info...New online portal merges vast data on Gulf of Maine ecosystem

"Our research is directed toward understanding why these runs see such different trends, by looking broadly at different systems subject to the same climate factors and constructing ecosystem conditions going back hundreds of years," Hilborn says. Hilborn is co-leader of the Alaska ...Programmable cells: Engineer turns bacteria into living computers
In a step toward making living cells function as if they were tiny computers, engineers at Princeton have programmed bacteria to communicate with each other and produce color-coded patterns. The feat, accomplished in a biology lab within the Department of Electrical ...Long thought extinct, ivory-billed woodpecker rediscovered in Big Woods of Arkansas
...saw an unusually large, red-crested woodpecker fly toward him and land on a nearby tree. He noticed several field marks suggesting the bird was an ivory-billed woodpecker. A week later, after learning of the sighting, Tim Gallagher, editor of the Cornell Lab of Ornithology's Living Bird magazine, and Bobby...ASU researcher creates novel 'bioelectronic signatures' to detect DNA mutations
