Reducing antibiotic use lowers rates of drug-resistant bacteria

...s leads to fewer "superbugs." That's the take-home message behind a new study in the Oct. 15 issue of Clinical Infectious Diseases, now available online. The study found that reducing antibiotic use for pediatric respiratory tract infections resulted in lower rates of carriage of drug-resistant bacteria. D...

Research Permits First-Ever Visualization of Psychological Stress in the Human Brain

...dapt to environmental challenges and threats. "The message from this study is that while stress may be useful in increasing focus, chronic stress could also be detrimental to mental health," concludes Jiongjiong Wang, PhD, Assistant Professor of Radiology and principal investigator of the study. "How the br...

Asian immigrants in NYC not receiving HIV education at religious institutions

These religious institutions are awash in "the tension between morality and compassion," Chin explained. Almost all of those interviewed agreed that it is important for the instit...

Hybrid grass may prove to be valuable fuel source

... sciences and of plant biology, recently took that message to Dublin, Ireland, where the British Association for the Advancement of Science sponsored the annual BA Festival of Science Sept. 3-10. Closer to home, two of Long's doctoral students, Emily A. Heaton and Frank G. Dohleman, delivered their Miscanth...

Bitter or sweet? The same taste bud can tell the difference

...mething bitter is on the tongue, while NPY sends a message that something sweet is being eaten. "We were sur..."But this would ensure that the brain gets a clear message of what kind of taste is on the tongue." Taste buds are really clusters of 50 to 100 cells. Nerve f...

Micro-molecule plays big role in birth defects

...or the human body, and RNA, which translates DNA's message into proteins - the building blocks of life. Scientists now think the pint-sized pieces of RNA may control as much as one-third of human gene expression by seeking out and binding to messenger RNA, thereby adjusting the protein-manufacturing process...

Say what? Bacterial conversation stoppers

...his common language does not guarantee the correct message gets through, the researchers discovered. In earlier work, Xavier had found that E. coli both produces and consumes AI-2. In this study, she set up an experiment where multitudes of E. coli first produced then devoured enough AI-2 to dim the ligh...

Size matters: Preventing large mammal extinction

...ge London. "From a conservation policy angle, the message would be: small may be conservable but it is a little trickier for the larger mammals," commented Dr Andy Purvis of Imperial College London. The research findings suggest smaller species, of around less than 3kg, would benefit from conservation of t...

Caloric restriction won't dramatically extend life span in humans: UCLA research

... speculated, evolutionary biologists report. "Our message is that suffering years of misery to remain super-skinny is not going to have a big payoff in terms of a longer life," said UCLA evolutionary biologist John Phelan. "I once heard someone say caloric restriction may not make you live forever, but it s...

When disease invaders pull that trigger, infected plants cells quickly commit suicide, often preventing the invader ...

UNC plant researchers discover proteins interact to form hair-trigger protection against invaders

Researchers make surprise discovery that some neurons can transmit three signals at once

...ach responsible for relaying one specific chemical message called a neurotransmitter. Either neurons release a neurotransmitter that excites a neighboring cell, thereby triggering an electrical discharge and enhancing brain activity, or they dispatch a signal that quells a neuron's activity.

Planthoppers and pachyderms Larom met O'Connell-Rodwell in Etosha in 1992, the year she began her work at Mushara. "I started doing research on elephants for the Namibian Ministry of Wildlif...

...ibiting memory storage. Bilbo says, "The take-home message is that immune responses in a healthy brain are tightly regulated and controlled; any alteration in these responses is likely to cause problems." She adds that, "Memory impairment in wild animals would undoubtedly have severe implications for surviv...

South America's vast pantanal wetland may become next everglades, UNU experts warn

In a message to mark World Water Day, March 22, UNU says the Pantanal provides enormous environmental services by storing and purifying water, providing storm protection and flood mitigation, and stabilizing the local climate, particularly rainfall and temperatur...

HIV Infection Still On The Rise

...icides have proved disappointing. Although the ABC message (abstinence, be faithful, use a condom) is popular with the American government, its application in other parts of the world may not have the impact required. In the face of this global catastrophe, the epidemic in the United Kingdom seems both smal...
