Scientists find fossil proof of Egypt's ancient climate

...reliable water resources, since it seems to be the strongest humid phase in this region over the past 400,000 years. We're also testing the hypothesis that humid events were more frequent than previously thought, which would have allowed for greater mobility throughout the region." The researchers noted that ...

Children's taste sensitivity and food choices influenced by taste gene

...dults. Instead, effects of race/ethnicity were the strongest determinants. Mennella comments, "What I find most interesting is that you do not see the relationship between bitter taste receptor genotype and sweet preference in adults. The forces of experience and culture appear to have overridden the genetic e...

Strongest proof yet found for prion hypothesis

UTMB scientists offer strongest evidence yet that infectious misformed proteins ca...dical Branch at Galveston (UTMB) have produced the strongest proof yet that the mysterious and devastating brain diseases known as "transmissible spongiform ence...

Supercomputers to focus brains on AIDS dilemma

...the researchers were also able to predict that the strongest binding inhibitors should be possible with moieties on both sides, what the scientists have called "butterfly" compounds with "wings" extending to both the east and west. "This pointed the way to new classes of drugs," said McCammon. "And it's very ...

Currents could disrupt ocean food chain

...e consume." The Atlantic Conveyer current has the strongest impact in the North Atlantic, but it is a global phenomenon, Schmittner said. Surface waters from the Pacific Ocean, the Indian Ocean, the Arabian Ocean and the southern Atlantic are pulled northward where they are cooled by the atmosphere in the Nor...

AIDS Public Awareness Campaign Expands Following Report Of Rapidly Progressive HIV

... City and Buffalo. New York State has some of the strongest confidentiality protections in place for HIV in the nation. "No one should be afraid to get tested for HIV," Dr. Novello said. "Remember, this virus knows no racial, ethnic, age or gender boundaries. It is what you do, not who you are, that puts you ...

What the eye doesn't see

...search from the University of Bristol provides the strongest evidence to date that disruptive patterns do indeed protect insects from detection by birds, the predator most likely to have shaped the evolution of protective coloration in insects. Professor Innes Cuthill and his team pinned artificial 'moths' to...

Research shows smoking adds a decade to reproductive age of IVF patients

...armful effects of smoking or being overweight were strongest among those women who had no obvious cause for not conceiving, according to the research, published today (Thursday 7 April) in Europe's leading reproductive medicine journal Human Reproduction[1]. Lead researcher Dr Bea Lintsen, from Radboud Univer...

Can our genes tell the story of our divergence?

...ception, as well as spermatogenesis, but found the strongest evidence for positive selection in genes related to immune defense. Immunity genes, the authors explain, were likely targeted throughout mammalian evolution, while the perception and olfactory genes probably reflect primate-specific adaptations. Nie...

A novel virus for croup

...nal, open-access journal PLoS Medicine makes the strongest association yet between a newly identified virus and the pediatric respiratory disease commonly known as croup. Following their recent description of the coronavirus HCoV-NL63, Lia van der Hoek and colleagues suggest this is one of the most frequentl...

'Shifty-eyed' Monkeys Offer Window Into Brain's Social Reflexes

...s at Duke University Medical Center have found the strongest evidence yet that monkeys show the same keen 'social reflexes' that humans do -- shifting their attention in response to the direction of gaze of another individual. The researchers said their findings mean that monkeys can provide a critically impor...

Nanotubes inspire new technique for healing broken bones

...rolled-up tube of chicken wire. They are among the strongest known materials in the world. Bone tissue is a natural composite of collagen fibers and hydroxyapatite crystals. Haddon and his coworkers have demonstrated for the first time that nanotubes can mimic the role of collagen as the scaffold for growth o...

Rutgers to lead $52.7 million protein research program

...epresentatives." NIGMS has now funded four of the strongest pilot program centers, including NESG, as Centers for Large-Scale Structure Production. The focus is shifting to a production phase in which the new centers will use methods developed during the pilot period to rapidly determine thousands of protein ...

Bacteria in Household Dust May Trigger Asthma Symptoms

...cation use, and wheezing. These relationships were strongest for bedroom floor and bedding dust. Households with higher endotoxin concentrations experienced higher prevalence of respiratory symptoms. Endotoxins are found in the cell wall of bacteria and are only released when bacteria ruptures or disintegrate...

Agricultural workers at increased risk for infection with animal flu viruses

...s compared with the control group. Farmers had the strongest indication of exposure to swine flu viruses, as much as 35 times higher than the control group. Similarly, comparable values were as much as 18 times higher for veterinarians and as much as 7 times higher for meat processors than the control group. I...

Past illegal blood donation in China linked to hepatitis C virus infection

... 3% in non-donors. Selling blood or plasma was the strongest independent predictor for HCV-positive findings. Receiving a blood transfusion was also independently associated with HCV; villagers who received blood transfusion had about 8 times the risk of HCV infection than those who had no history of blood tra...

Scientists observe how a close bond activates the immune system

...gues discovered that the T cell receptor signal is strongest when they are physically held in the outer ring of the bull's eye rather than the center. "We locked the receptors in the periphery and saw enhanced signaling over a prolonged period of time. It was quite a surprise," says Dr. Dustin. Researchers h...

Team led by Carnegie Mellon University scientist finds first evidence of a living memory trace

...like a fingerprint that disappears over time. It's strongest after the honeybee's initial exposure to an odor, but you can still detect its signature features minutes afterwards," said Galán. A future question that could be addressed using this research is addressing how short-term memory gets encoded as lon...

Penicillin, amoxicillin: Step aside for strep throat treatment

...f throat infections, doctors try to preserve their strongest antibiotics for the most severe cases. But most doctors would view a drug that fails in one out of four patients, as penicillin does in strep cases, as unacceptable, Pichichero said. To understand why the older drugs don't work as well, consider a c...
