Breaks in hibernation help fight bugs

...the answer lies in bacterial infections that could run rampant in the face of an immune system that is essentially asleep. "Animals cannot tell when they need to wake up, or if they are infected," says Luis. If the animals hibernate for long they risk serious infection, she says, while waking up frequ...

Encoded metallic nanowires reveal bioweapons

...face but instead in a suspension, which makes them run much faster and more accurately. If nickel stripes are also added to the ends of the wires, they can then be magnetically separated out during the required washing steps--a prerequisite for a portable microbiodetector. ...

First-ever genomic test predicts which lung cancer patients need chemotherapy to live

...NA translates a gene's DNA code into proteins that run the cell's activities. Hence, it is a barometer of a gene's activity level inside the cell. Scientists label the messenger RNA with fluorescent tags. The fluorescent RNA is then placed on a tiny glass slide, called a gene chip. There, it binds to ...

When it comes to gene transcription, random pauses aren’t quite so random, study finds

... trip, that would be a random phenomenon. But if I run down the road and every time I trip there's a pothole, then that's not random." Some researchers have argued that all pauses might be associated with either hairpin formation or backtracking, but the Cell study contradicts that assumption. "Most ubi...

Researchers offer clues to how leaves patterns are formed

...nstitutes of Health (NIH). The grant, which will run over four years, comes at a perfect time. "More than 1,000 research laboratories from over 50 countries are holding ARP/wARP licenses and by June this year our paper that described the key innovative feature of ARP/wARP in Nature Structural Biology i...

Loosen up, DNA: Leukemia gene changes genetic packaging

...ase and grow new blood cells, but when its signals run amok, those people are much more likely to get any one of several types of leukemia or lymphoma. To learn more about how JAK/STAT works, a team led by Willis Li, Ph.D., assistant professor in the Department of Biomedical Genetics, devised a comple...

Tigers get a business plan

...Laos and Cambodia, where current tiger numbers may run below ten individuals may see tiger numbers jump four-fold over the next decade. It is these types of hard numbers that attracted have attracted venture capitalist and WCS trustee Michael Cline and Tom Kaplan, both of the Panthera Foundation to ...

Diabetes research takes wing thanks to long-lived fruit fly

... known as free radicals zing through materials and run roughshod over anything in their way, including vital proteins and DNA. It's a major reason why generally our bodies falter as we age ?we're literally dinged to death by free radicals. While scientists knew that JNK in a fly cranks up the anti-oxida...

Inheriting a tendency to brain infection

Might some infectious diseases run in families because one inherits susceptibility to them? Although researchers generally agree that an individual's genetic makeup contributes in subtle ways to susceptibility to infectious disease, new findings from researchers in France support the ...

Crohn's disease gene identified

...t over one million Americans. Because IBD tends to run in families and is more frequent in certain ethnic populations, especially Ashkenazi Jews, scientists have long suspected a significant genetic component. According to senior author Judy H. Cho, M.D., associate professor in the Departments of Medi...

Protowings may have helped bird ancestors cover rough terrain

...s, concentrating on chukar partridges. Chukars can run 12 hours after hatching, but they cannot fly until they are about a week old. Even before they are able to fly, however, the birds flap their developing wings in a characteristic way while running, which improves their ability to climb steep slopes a...

New finding points way to foiling anthrax's tricks

...d a trick that anthrax bacteria use to make an end run around the body's defenses, but which may turn out.... Hoette approached an anthrax research laboratory run by B. Rowe Byers, professor of microbiology at the University of Mississippi Medical Center, to obta...

Circadian gene helps the brain predict mealtime

...o play an important role in the brain's ability to run its central circadian clock according to daylight. The researchers found that, interestingly, synchronization of timing between organs by scheduled meals is not affected by the Period 2 mutation, indicating that this gene is not crucial for sched...

Emotional control circuit of brain's fear response discovered

...anism to prioritize and refine responses –we don't run away from every loud sound or unexpected sight," said Dr. Hirsch. "Following the discovery of the amygdala's role in fear response, we decided to explore the finer points of the neurocircuitry of fear ?how it is regulated/controlled in the brain." ...

Gene chip technology shows potential for identifying life-threatening blood infection

...of infection, wouldn't it be wonderful if we could run a blood test in the emergency department and more accurately triage patients so they could be treated earlier with the appropriate antibiotic," Cobb says. The researchers used microarrays, also called gene chips, to analyze patterns of gene expres...

Biofuel cells without the bio cells

...How bright? "The peak current, or flux, doesn't run long, just a few seconds," Squier said, "but flux is at least as good as what you would find in the most efficient bioreactors, which rely on living bacteria." Biological fuel cells, or biofuel cells, are not yet powerful enough to be commercially ...

Jefferson scientists find high glucose before surgery raises risk of dangerous complications

Chemical tests of cell growth enter third dimension

...ents to the cells in the middle well, so tests can run for up to two weeks without researchers having to replenish the growth medium. "If you replenish the medium, you could essentially grow cells indefinitely," Yang said. The second new technology to come from Yang's lab is a microfluidics platform th...

Distinguishing friend from foe in the battle against cancer

...targets mutant enzymes or "oncoproteins" that have run amok and now promote uncontrolled cell growth. As promising as these drugs are, cancer cells with their backs against the wall have the tendency to fight back. A major goal of cancer research is to frustrate these acts of cellular desperation. In a ...
