...al posteriomedial (VPM) thalamus of awake, quietly resting rats. Microstimulation of the LC output enhanced norepinephrine influx in VPM and modulated the responses of individual units (neurons) to whiskerpad stimulation. Although units could show cell-specific behaviors, as a group, the responsiveness of VP...

Clue found to Epstein-Barr virus' ability to form and sustain tumors

... of amino acids prevented EBNA-1 from transforming resting B cells into proliferating cells. Under normal conditions, a cellular protein binds this 25-amino acid segment of EBNA-1, allowing transcription of viral and cellular genes regulated by EBNA-1 to occur. Hammerschmidt and Sugden are now trying to ide...

Burning wetlands unleash sequestered mercury in wake of climate change

... in Alaska and northern Canada have been efficient resting places for mercury. "When we walk across the surface of a peat land, we are standing on many thousands of years of peat accumulation," Turetsky said. "This type of wetland is actually doing us a service. Peat lands have been storing mercury from th...

Sleepy fruit flies provide clues to learning and memory

...fruit fly. "Fruit flies and humans share similar resting patterns," explains Sehgal. "Like humans, the sleeping states of fruit flies are characterized by periods of immobility over a twenty-four hour period, during which the fruit flies demonstrate reduced responsiveness to sensory stimuli." By tinkering ...

RIT students design deep-sea explorer to search for Lake Ontario shipwrecks

...ice will be used to explore century-old shipwrecks resting on the bottom of Lake Ontario and the Atlantic Ocean--giving human explorers their first glimpses of some all-but-forgotten vessels lost to the seas. The nine-member RIT team is led by Dan Scoville, a 2005 RIT graduate who has located and explored th...

According to the researchers, cells lacking K17 speed from growth to death faster than normal cells, preventing sufficient hair growth. When cells of normal hair follicles die, they follow a specific and genetically con...

"BC has also taught me that I'm not only responsible for myself and my research, but for society as well," said O'Day. "I am so grateful for what s...

"For genes, this is equivalent to resting one finger on the trigger," said Stuart Schreiber, an author of the Cell paper, the director of the Chemical Biology program at the Broad Institute, and professor at Harvard University. "This approach could be a key strategy for keeping crucial genes...

Restoring seagrass beds: Is it for the birds?

... hoping to attract seabirds to use the stakes as a resting area where they can "do their business" and fertilize the shoal grass beneath them. "Birdstakes have proven successful in the Florida Keys," comments Dr. Heck. "We're placing signs in marinas and along the grassbed borders warning boaters against us...

How does the brain know what the right hand is doing?

After the arm was paralysed and anaesthetised, the subjects were unable to detect when researchers moved their hand, but incorrectly thought that they were still able to move it themselves when they tried...

...ble to crystallize the apolipoprotein (unbound) or resting form of GluR5 S1S2, their results suggest that kainate receptors undergo much larger conformation shifts than has been suggested by structural studies of AMPA receptors. Interestingly, large movements are the norm for their ancestors, the bacterial p...

...ad a bigger effect on reactivity to stress than on resting blood pressure. "Some genes may lie dormant when life is sweet and calm, but swing into action when we are stressed," he said. The researchers at the symposium said they believe that using genetic markers to determine who is at greater risk of healt...

"If we have a protein sequence from bone, we can tell if the material is an original part of the organism that will provide interesting information about its past. We can k...

Getting old? Slowing down? Blame inefficient mitochondria

...of the University of Washington, Seattle, compared resting muscle cells from young (7-month) and old (30-month) mice. They found that old muscle used around half as much energy as young muscle, but that the mitochondria used just as much oxygen at both ages. This represents a 50% loss in efficiency. "The bes...

What we have learned now is that there is no resting state, that even in the absence of substrates, before catalysis, defined motions of many atoms is an intrinsic property of these enzymes," explained Kern. "Much like a rousing basketball game in which all the players continuously but strategically ...

In other words, while metabolic activity per unit body mass varies within a group of organisms, such as mammals, it tends not to vary much when two diverse groups of organisms that differ greatly from each other in size are ...
