Prenatal Stress Keeps Infants, Toddlers up at Night, Study Says

...life, or if both conditions merely fall out of the same stressful pregnancies. Related studies now show that stress, which is associated with increased exposure stress hormones, like cortisol, may disrupt a childs formation of a bundle of nerve cells in the brain called the suprachiasmatic nucleus w...

Carnegie Mellon scientists find key HIV protein makes cell membranes bend more easily

...eticians think about virus-cell interactions. This same phenomenon could provide a general way that viruses use to infect cells, so it will be exciting to look at other viral systems with our experimental method,” she said. Many different viruses could enter cells by efficiently lowering the energy requi...

Scratch no more: Gene for itch sensation discovered

..." Chen says. "The knockout mice seemed to have the same reactions to painful stimuli as normal mice." But when post-doctoral fellow Yan-Gang Sun, Ph.D., injected the spinal cords of normal mice with a substance that stimulates GRPR, the mice started scratching themselves as if they had a bad itch. "That'...

One species, many genomes

...t of humans or corn—even though it has about the same number of genes. In contrast to these other genomes, there are few repeats or seemingly irrelevant filler sequences. "That even in a minimal genome every tenth gene is dispensable, has been a great surprise," admits Weigel. Detailed analyses showed...

Common cancer gene sends death order to tiny killer

...small chains of ribonucleic acid (RNA) made by the same machinery that produces other types of RNA in the cell, such as the messenger RNAs that carry the instructions to make proteins. Once produced, microRNAs stick to messenger RNAs and, like crumpled paper jammed in a copy machine, prevent proteins from...

...sical stimulus, paxillin consistently moved in the same direction as the fluid flow. Paxillin is found primarily at focal adhesions, busy intersections of activity scattered around the cell’s cytoplasmic membrane. Focal adhesions are regions rich with receptors for growth factors and they are also stru...

Blood test may help signal tumor's remission, return in throat cancer patients

... growth factors and cytokines is controlled by the same “master switch”—a regulator protein known as nuclear factor kappa B (NF-kappaB)—the researchers suggest that this protein may represent a new target for drug therapy. Drugs that help turn off NF-kappaB are currently being tested in clinical trials at...

Old memory traces in brain may trigger chronic pain

...ber, where they remained. Next scientists took the same rats and treated them with D–Cycloserine. Again, scientists stimulated the rats’ sensitive limbs. This time, however, the rats remained in the dark chamber. “Their aversive reaction to the stimulation disappeared,” Apkarian said. Based on th...

Research team identifies new Alzheimer's gene

...hs of work and thousands of dollars to achieve the same result. Moreover, it paves the way for even more advanced studies using larger sample populations, more powerful array chips that can distinguish more genetic markers, and more sophisticated methods of analyzing the data....

Bigger horns equal better genes

...e success," Coltman said. "We wanted to see if the same could be said for alpine ibex, and we found that it can." The researchers were particularly intrigued about the ibex's horns because they are costly for an ibex to produce and maintain. "[The horns] require a lot of energy to build and then ca...

Largest synthetic gene ever built offers insights into anti-malarial drug resistance

...rom this synthetic gene. They previously used this same technique to create and express a synthetic version of the much smaller PfCRT gene. PfMDR1 is made up of about 4,000 base pairs and its protein is particularly large, Roepe said, making the recent work much more challenging. Already, analysis of ...

Pesticides choke pathway for nature to produce nitrogen for crops

...20 commonly used agricultural chemicals shared the same mechanism of action as PCP, but with varying amounts of signal disruption. Fox, McLachlan and colleagues, in their PNAS paper, pointed to two published studies from 2000 that had found significant declines in both crop yield per unit of synthetic...

The laboratory animals showed no harmful effects from the treatment, though Hotamisligil cautioned that experiments were not designed to ...

New collaborative research reveals chimpanzees can sustain multiple-tradition cultures

For years, pri...

Professor Inglehearn hopes that the findings will be useful to inform and counsel the families most at risk, particularly within the Pakistani...
