UCSB study on sibling detection mechanism highlighted in Nature
02-15-2007 · EurekAlert!A team of researchers at the University of California, Santa Barbara, has found evidence of a nonconscious mechanism in the human brain that identifies genetic siblings on the basis of cues that guided our hunter-gatherer ancestors. Their findings will be published in the Feb. 15 issue of the science journal Nature.

- Newly identified mechanism for silencing genes points to possible anti-cancer strategies
05-16-2007 · EurekAlert!
Scientists are only beginning to appreciate the extraordinary degree of control exercised over every step of the gene-to-protein production process. Only about 10 percent of human genes, for example, are active in a given cell at a given time, with the remaining 90 percent silenced by a various mechanisms. In a just-published study in Nature, scientists report an important new gene-silencing mechanism that points to promising potential targets for anti-cancer interventions.

- Mechanism of microRNAs deciphered
05-16-2007 · EurekAlert!
Researchers from the European Molecular Biology Laboratory (EMBL) have developed a new method that uncovered the mode of action of microRNAs in a test tube. The study, which is published in the current online issue of Nature, reveals that microRNAs block the initiation of translation, the earliest step in the process that turns genetic information stored on messenger RNAs into proteins.

- Study reveals aspirin's colorectal cancer prevention mechanism
05-23-2007 · EurekAlert!
Aspirin therapy's ability to reduce the risk of colorectal cancer, seen in a large number of studies, appears to depend on the drug's inhibition of the COX-2 enzyme, the action that also underlies aspirin's usefulness for treating pain and inflammation. Investigators from Massachusetts General Hospital, Dana-Farber Cancer Institute and Brigham and Women’s Hospital have found that regular aspirin intake only reduced the incidence of colorectal tumors that overexpress COX-2.

- Einstein researchers discover important clue to the cause of Parkinson's disease
01-02-2008 · EurekAlert!
A glitch in the mechanism by which cells recycle damaged components may trigger Parkinson's disease, according to a study by scientists at the Albert Einstein College of Medicine of Yeshiva University. The research, which appears in the Jan. 2 advance online issue of the Journal of Clinical Investigation, could lead to new strategies for treating Parkinson's and other neurodegenerative diseases.

- Level-headed: Economics experiment finds taste for equality
04-11-2007 · EurekAlert!
The rich don't get richer -- at least not in laboratory games. According to a new study of behavioral economics, published in the April 12, 2007, issue of Nature, people will spend their own money to make the rich less rich and the poor less poor. They do so without any hope of personal gain, acting, it seems, out of a taste for equality and sense of fair play.

- Salk scientists hammer out a pathway that promotes muscle cell survival in mice
04-29-2007 · EurekAlert!
Scientists at the Salk Institute for Biological Studies have identified an enzyme that pumps up a cell's ability to maintain healthy muscle and restores normal muscle function in genetically engineered mice with weak muscles. The study, published online in Nature Medicine, is the first to explore the part this enzyme plays in a cascade of events triggered by exercise-induced hormones and other signals.

- Double identities lie behind chromosome disorders
07-08-2007 · EurekAlert!
Chromosome disorders in sex cells cause infertility, miscarriage and irregular numbers of chromosomes (aneuploidy) in neonates. A new study from Karolinska Institutet published in the scientific journal Nature Genetics shows how chromosome disorders can arise when sex cells are formed.
