... increase. "In the proteomics world, things are changing so rapidly," Bystrom said. "We in this lab have to be flexible in dealing with a wide range of samples, everything from bacteria to humans."

Surprisingly, even though no adult males from this period remained in the Forest Troop in 1993 (males migrate after puberty), new males were also less agg...New method is first to mimic subtle genetic changes
... in the laboratory because traditional methods for changing levels of gene expression tend to also disrupt multiple elements that are required for gene function, thereby making it nearly impossible to draw conclusions related solely to quantitative differences in gene expression. Dr. Oliver Smithies and colle...Scientists question reports of massive ant supercolonies in California and Europe
... nonaggressive nestmates into combatants simply by changing their diet. "It seems really clear that aggression in Argentine ants, as in most ants, is related to how they smell, and that seems to be related to food or environmental influences," Gordon noted. "Again, there isn't any evidence that there's...Fat hormone leptin alters brain architecture and activity, which in turn drives feeding behavior
...kefeller scientists discovered that leptin acts by changing the wiring of the brain, a phenomenon known as plasticity. The hormone alters the wiring by controlling synapses -- the inputs and outputs to neurons that, in this case, regulate feeding behavior. "This is a very dynamic effect that's quite dramatic...Antarctic fish study may aid cardiac research

"We'd like to look at all our options and combine them into the most potent inhibitor we can manage - that's a good goal for the near future." ...Study points to possible cause of asthma exacerbations
... sensitivity in lung epithelial (surface) cells by changing expression of receptors on those cells. Using cell models, the team specifically showed that respiratory syncytial virus (RSV) infection increases the number of a type of receptor called Toll-4 on the airway cells.

By analyzing the changing patterns of expression of more than 2000 genes in the developing cerebellum in mice and comparing these to genes expressed in human medulloblastomas, the investigators were able to characterize the malignant cells from a developmental perspective. ...Preoperative treatment with Arimidex(TM) allows patients to undergo less extensive surgery

...ggestions include altering fishing practices, like changing the depths at which the hooks are set. "Perhaps places could be located in the ocean where there are still swordfish to catch but fewer turtles, redirecting the fishery to where the bycatch rate might not be as high," Crowder said.
