Obese people are more sensitive to pain, suggests study

...y to contract and move the muscles in order to get away from the source of the pain. "This kind of evaluation is in some ways a more objective way of measuring the body's response to pain, as opposed to simply asking someone if they feel pain," Emery said. But the researchers did ask participants how mu...

Suicide risk does not increase when adults start using antidepressants, study finds

... should seek help from a doctor or therapist right away if that happens," says Simon. "But our study showed that on average, the risk of suicide actually goes down after people start taking the antidepressant." Simon agrees with the FDA's recommendations that doctors carefully monitor people taking anti...

Research tracks whales by listening to sounds

...ick up right whale sounds from about 40 kilometers away ?and even farther, if the waters are shallow and the terrain even. Using those hydrophones, Mellinger discovered a number of sperm whales living in the Gulf of Alaska in the winter. The hydrophones picked up almost half as many whale sounds as in th...

Secrets of the sea yield stronger artificial bone

... measures half of a micron. "We are half a micron away from mimicking nature," says Tomsia. After the ice is removed via sublimation, the result is a porous scaffolding composed of hydroxyapatite that exhibits striking similarities to nacre's multilayered structure across a wide range of length scales. ...

Teens unaware of sexually transmitted diseases until they catch one, Carnegie Mellon study finds

...t about these other diseases, and so they may come away with a false sense of confidence," she said. The study's findings are troubling because teenagers who know little about STDs are more likely to engage in risky sexual behavior and to delay the treatment of STDs. And the consequences are severe. Geni...

All placebos not created alike

...d to cause them. This study takes the first step away from examining the placebo effect as a generalized phenomenon to one investigating how it varies in specific clinical environments. Kaptchuk and his colleagues have initiated other National Institute of Health funded studies that will explore the pla...

This expands the possibilities for drug design, he said. "Instead of an active site inhibitor, you could screen for a TEN domain inhibitor." ...

"Although people have known about the CPG for a long time, they haven't been able to identify the nerve cells that are part of these circuits. Even at closer inspection, the spinal cord is just a jumbled mass of hundreds o...

Uncovering sex-change secrets of black sea bass

Tumor cells that border normal tissue are told to leave

...al tissue receive signals that tell them to wander away from the tumor, allowing the cancer cells to establish deadly metastatic tumors elsewhere in the body. The researchers say their discovery demonstrates the importance of the tumor's environment and shows more precisely how the metastatic process oc...

New mechanism for essential genome-wide gene silencing identified

..., the great majority of genes are silenced, locked away within the compacted but orderly material that makes up chromosomes. Estimates are that only about 10 percent of the roughly 25,000 genes in the human genome are activated, or "on," at any given time in a particular cell ?the default setting for most...

Researchers unravel DNA tangles and enzyme seamstresses

...as strands of unlinked DNA molecules tend to curve away when they touch each other. The findings could have implications in designing new drugs to treat cancer and infectious diseases as uncontrolled DNA linking and tangling often result in cell death. "The exciting part is that these seemingly abstract...

UF researchers develop ways to keep the bloom on the rose

The findings also can be applied to lilies and alstromeria, to keep their leaves green even after they go into a vase. Previously the leaves of these crops were susceptible to yellowing, said Nell. He ant...

U-M scientists identify major psoriasis susceptibility gene

... About half the time, strep-induced psoriasis goes away and never comes back. But for the other 50 percent of young people who get it, psoriasis progresses to become a chronic life-long disease." The PSORS1 gene is actually one of over 20 different varieties (scientists call them alleles) of a gene calle...
