UCSF scientist Joe Derisi named MaCarthur Fellow
...Scientists bond DNA or RNA sequences to the slide, wash fluorescently tagged DNA or RNA sequences of interest over it and see where the two sets of nucleic acid match up, as indicated by the fluorescent light. The outcome reveals which, if any of the genes in the sample of interest are active. ...Macrophages, not stem cells, correct liver disease by fusion
... macrophages into the liver, which would otherwise wash cells away in its blood-rich environs. The result was "robust production" of functional hepatocytes..

...bricks to fortify a fence so it can withstand the wash of acids that it sends pouring into the mouth. The Rochester team found that a gene known as fabM is responsible for changing the membrane's composition and enables S. mutans to become more resistant to acid. The same gene had previously been discov...UCLA study sheds new light on island evolution
...their 12-month study: Hurricanes and lesser storms wash the lizards into prevailing ocean currents, which carry them from island to island. "The lizards are being prevented from evolving as quickly as they otherwise would have," said Calsbeek, the study's lead researcher. "We can no longer just assume tha...Study shows prions stick around in certain soils
...pread it. Whereas prions in sandy soils either may wash away or travel deeper into the ground, says Pedersen, those in clay soils may remain near the surface. "Because the material may be more available for ingestion by animals," he explains, "the rate of infection may be greater." Analyzing the absorptio...How a little bit of cold can kill a big manatee, and what it might mean for the species
...pells, sick, sometimes emaciated manatees at times wash up along the coast of Florida afflicted with a puzzling combination of skin sores and infections that clinicians historically treated as separate ailments.

Eating too many of these flying foxes could be dangerous because they like to eat cycad seeds, which contain a neurotoxin called BMAA (beta-methylamino L-alanine).

However, there is strong evidence for a genetic component (the risk of developing OCD is higher in the relatives of affected), and for the involvement of the serotonin (5HT) neurochemical s...Gulf buoy network to aid in red tide early warning systems
...apher Lisa Campbell thinks waiting until dead fish wash up on the beach is too late to identify the onset of toxic "red tides" in the Gulf of Mexico. What is needed is an early-warning system to detect the presence of the tiny toxic algae before they reach bloom proportions. Campbell, a professor in th...Extreme climate variance sped extinction of local butterfly populations, researchers say
