Large-scale forces shape local ocean life, global study shows
... more than 14 years to complete. It led to another key finding: Latitude also plays a big role in local species richness. At the poles, partly due to the harsh environment and glacial scouring, there are fewer species. But moving closer to the equator, the number of species increases. While...Early life stress can inhibit development of brain-cell communication zones, UCI study finds
...archers have identified how increased amounts of a key messenger for stress, the neuropeptide CRH, can inhibit the normal growth of dendrites, which are branch-like protrusions of neurons that send and receive messages from other brain cells. The researchers believe CRH ultimately may be responsible for...New DNA repair enzyme makes mistakes to save lives of cells
...tudy published online today, is believed to play a key role in maintaining the integrity of a cell's genetic information the basis by which the life of a cell or species is preserved by allowing its DNA to be replicated despite discovery of a mishap on the sequence that it corrects with a new mistake. ...Molecular mechanism sheds light on neurodegenerative diseases
...imoto, John Evans Professor of Biology, has made a key discovery toward understanding one of these mechanisms. In studying toxic proteins involved in Huntington's disease, they discovered that the disease-causing protein severely interferes with the working of the proteasome, the cellular machine respons...Mouse study: 'Critical' Down syndrome region isn't
...se might be modifiable -- if we can figure out the key players." As part of this effort, Olson used a technique to precisely duplicate a defined chromosome segment and applied it to the DSCR section on mouse chromosome 16, the analog of human chromosome 21. She also made a mouse chromosome 16 that lacked...Clues to improving TB treatment

...on and low blood magnesium levels proved to be the key to tracing the genetic cause of the array of pathologies. Since low magnesium occurs infrequently in the general population, the researchers tested her for known mutations that they had previously associated with that trait.

... Primate Research Center (ONPRC) have identified a key gene that impacts the timing of puberty and can shorten the time span for reproduction. The research was led by Sergio Ojeda, Ph.D., head of the Division of Neuroscience and a senior scientist at ONPRC. The work will be presented at the Society for N...Soaking up signal: Endocytosis controls spreading and effective signaling range of Fgf8 protein
... One member of this growth factor group, Fgf8, has key functions during the development of such structures as the vertebrate brain, heart, and inner ear. Growth factors such as Fgf8 are emitted by particular cells and travel within tissues in the extracellular space, where they signal to the "target" cel...Potential new oncogene may be missing link in cancer-causing chain

..."Knowing the organization of the mouse genome is a key component to identifying which gene-environment interactions are linked to disease in humans," said Dr. William Schrader, Director of the Center. "We'll start by mapping the DNA of 15 strains of mice most often used by researchers to study susceptib...Passage of Marin County GMO ban would encourage widespread use of harsh pesticides
