No role for simian virus 40 in human pleural mesotheliomas

...V40 infection might be a possible mechanism in the remaining 20 percent," said Marc Ladanyi, M.D., Director, Diagnostic Molecular Pathology Laboratory,and the study's senior author. "But instead we found no evidence for SV40 in these tumors and our experiments show for the first time how the assays commonly us...

'Fossil genes' reveal how life sheds form and function

...mpletely absent from all three, with only a single remaining gene marking the pathway like a faded signpost. "Evolution repeats itself," Carroll says. "What we see is that three or four times, these genes have been junked in different species. The process of sweeping these genes away is more complete in these ...

European common frog found to use novel mating strategy

...pportunity exists for other males to fertilize the remaining eggs in the clutch. The researchers found that without clutch piracy, between 65 and 85 percent of eggs -- and sometimes as little as 20 percent -- were fertilized. The percentage was about the same with clutch piracy, but averaged 90 percent if, as ...

Researchers report new gene test for isolated cleft lip and palate

...e more than 150 such syndromes, accounting for the remaining 30 percent of all cleft lip and palate. Upon detailed analysis of the IRF6 gene, the researchers noticed a variation in the DNA sequence that they guessed may play a role in causing isolated clefts. The team reasoned the variation would somehow inter...

DHA-rich diet protects brain from Alzheimer's damage, UCLA study shows

...or all possible variables, DHA was the only factor remaining that protected the mice against the synaptic damage and memory loss that should have resulted from their Alzheimer's genes," said Cole. "We concluded that the DHA-enriched diet was holding their genetic disease at bay." Frautschy and Cole plan to p...

Around nine weeks later the hatchlings emerge en masse and head into the sea, one day to return when they reach maturity and lay eggs themselves. However each turtle's return is by no means certain.
