Nutrient pollution causes a long-term effect on Chesapeake Bay ecosystem
... type of fish have changed. Fish populations have shifted from species living near the seabed to those living in the upper waters. This shift may lead to food chain inefficiencies that favor production of bacteria and small invertebrates. Even in some Chesapeake Bay tributaries such as the Potomac and P...Greasing interferon's gears may pave way to greater therapeutic benefits, fewer side effects
... to genes in the cell nucleus. The modification up shifted Stat1's response to interferon. The study will appear in the October 7, 2005 issue of the Journal of Biological Chemistry and was selected as the journal's Paper of the Week, which recognizes the top one percent of the journal's papers in significan...Displaced songbirds navigate in the high Arctic
... found that both adult and juvenile birds abruptly shifted their orientation from the migratory direction to a direction leading back to the breeding area or the normal migratory route, suggesting that the birds began compensating for the west-to-east displacement by using geomagnetic cues alone or in combin...K-State eye researchers focus on stopping spread of damaged eye cells
...l cell damage, Takemoto said its primary focus has shifted to the injection methods. "I think it would be extremely big to get something into the eye by the injection of something intravenously," she said. "Overall, there's not much being done right now on delivery to cross the blood-ocular level. That's re...Mouse model of Rett Syndrome displays reduced cortical activity
...y-inhibitory balance in the cortex of the mice was shifted towards inhibition (decreased brain activity). They surmise that this shift toward inhibition in the cortex and perhaps other brain regions could underlie some of the cognitive, motor, linguistic and social symptoms seen in RTT.

The strategy is to mutate each gene, to observe the consequences, and investigate the molecular mechanisms. In the past two decades, only a small percentage of the genes shared by mic...New technique could alter field of mouse genetics
...hand, over the last few years many scientists have shifted their attention to determining the function of all of those genes. The strategy is as systematic as the genome sequencing projects -- mutate each gene, observe the consequences, and investigate the molecular mechanisms.

Although the overall contaminant concentrations in the grizzlies are lower than many other species of animals that consume marine food, the researchers from Canadas Departmen...Scientists find evidence of catastrophic sand avalanches, sea level changes in Gulf of Mexico
...hen sea level fell so low that the Texas shoreline shifted almost 100 miles to the south. The data are important to reconstructing climate change history and gathering insights about the development and placement of natural resources, particularly gas and oil deposits.

...ng gas prices," Berman said. "Hybrids have quickly shifted from a feel-good ideological purchase to a bottom-line, cost-conscious decision. Hybrids cars are clearly going mainstream." According to the survey, saving money on gas and cutting down on air pollution were the top two reasons for owning a hybrid ...Brain networks change according to cognitive task

In both, subjects were asked to read individual words and then make a spelling or rhyming judgment.

More recently, Trivers shifted gears to the consideration of the biological evolution of "selfish genetic elements," genes within an individual which advance their own replication at the expense of the larger organism.
