Scratch no more: Gene for itch sensation discovered

... very disruptive, interfering with sleep or giving rise to scratching that leads to scarring. Effective treatment options for itchy patients are limited. Historically, scientists regarded itch as just a less intense version of the pain sensation. As a result, research on itching has been somewhat neglect...

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

... in remission, while those who experienced a large rise over time in those proteins frequently exhibited a return of throat cancer. The findings could help lead to the development of a blood test that enables doctors to detect the recurrence of throat cancer early on, when there is still time to pursue a ...

Gene therapy study shows safety and statistically significant improvement in Parkinson's disease

...rain region, as surgical approaches typically give rise to immediate, short-lasting benefit around the time of surgery, while prior studies of AAV-mediated gene therapy show that gene expression gradually increases to a maximal level over a period of weeks. “We are very encouraged by the results of th...

Global survey of lizards reveals greater abundance of animals on islands than on mainland ecosystems

...vulnerable than those on the mainland to sea level rise and increased storm activity, which are expected by many scientists to become worse as a result of global warming. Jetz and Buckley gathered 643 estimates of lizard abundance from around the world for their survey, the first extensive global study...

Climate change impacts stream life

Newborn neurons like to hang with the 'in' crowd

...brain region harboring neural stem cells that give rise to new neurons. Newly born neurons infected with virus were marked by a fluorescent dye enabling the researchers to follow their fate over time as they tried to get accepted into the existing circuitry. With the help of a whole arsenal of high-tec...

Better health twice as likely for nonsmokers who live and work with smoking restrictions

...omes, and as smoke-free air legislation spreads, a rise in protection from secondhand smoke at home can be expected. "However, this does not, preclude the need to take a proactive approach to increasing adoption of household bans," says Dr. Shelley. The study suggests that while household smoking ban...

Study warns deep-sea mining may pose serious threat to fragile marine ecosystems

...etals is growing rapidly, and along with the sharp rise in metal prices, we have seen the depletion of metal-rich terrestrial mines," says Halfar. "For mining companies and their investors, undersea mining offers high concentrations of ore at relatively low production costs." The mining operations will...

Study shows dramatic increase in Caesarean sections

...rnal of Obstetrics and Gynaecology, found that the rise could not be explained by increases in clinical reasons for caesareans such as complications in pregnancy or labour/delivery and was more likely due to societal factors. The research project looked at all births in Western Australia between 1984 and...

In obesity, brain becomes 'unaware' of fat

...bigger and fatter and leptin increases, SOCS-3 may rise to decrease the signal. It seems that in obesity, SOCS-3 might end up overriding the [leptin] signal completely.? When the amount of fat in the animals?diets was reduced—even without any reduction in calories—the mice continuously lost weight until...

Gene found for rare disorder may reveal new pathway in mental retardation

Studying mutations that give rise to a rare genetic disease, genetics researchers have identified a novel biological pathway that may have a broader role during human development, potentially in cases of mental retardation and autism. An international team of researchers identified...

Researchers learn what sparks plant growth

...e models to predict how they work together to give rise to the tremendous diversity of shape and form found in the flowering plants," said Chory. For the moment, the research is an important addition to the fundamental knowledge of plant growth and survival. But the research and the work to follow have...

New compound prevents alcoholic behavior, relapse in animals by blocking stress response

...hol dependence in animals. CRF levels in the brain rise in the short term after drinking; in subjects that are not dependent, this activation returns to normal within a day or so. The new study shows that the CRF system becomes overactive in the long term in animals with a history of alcohol dependence, i...

How appetite-stimulating brain cells work overtime during fasting

... food intake." While it is as yet unproven, the rise in UCP2 in the brain likely also causes changes in temperature in the same way that UCP1 does in brown fat, Diano said. "It's possible that heat may act like a neurotransmitter of a sort," Diano said. Neurotransmitters are chemical messengers tha...
