Environment: Speaking the same language on noise exposure

Quantifying noise exposure will be significantly easier thanks to a new set of common noise assessment methods published today. Comparable data on noise exposure in Europe is a prerequisite to set up EU policies to reduce noise pollution, a growing health and economic concern all over Europe. The new methods – known as Common Noise Assessment Methods in Europe (CNOSSOS-EU) – were drawn up by the European Commission's in-house science service, the Joint Research Centre.

X-rays reveal the self-defence mechanisms of bacteria

Many pathogenic bacteria are able to go into a dormant state by producing persister cells that are not susceptible to conventional antibiotics. This causes serious problems in the treatment of life-threatening diseases such as tuberculosis, where the presence of persister cells often leads to a resurgence of infection following medical treatment.

Whole-genome scan helps select best treatment for childhood cancer

A whole-genome scan to identify large-scale chromosomal damage can help doctors choose the best treatment option for children with neuroblastoma, one of the most common types of childhood cancer, finds an international collaboration jointly led by The Institute of Cancer Research, London.

The researchers called for all children diagnosed with neuroblastoma worldwide to have a whole-genome scan as a standard part of their treatment.

New test to crack down on sporting drugs-cheat test

Scientists from three UK universities have developed a new test to catch drugs-cheats in sport.

Over the last 10 years, the GH-2004 team, which is based the University of Southampton, has been developing a test for Growth Hormone misuse in sport with funding from the World Anti-Doping Agency (WADA) and US Anti-Doping Agency and with support from UK Anti-Doping.

Study: Gingko biloba does not improve cognition in MS patients

PORTLAND, Ore. – Many people with multiple sclerosis for years have taken the natural supplement Gingko biloba, believing it helps them with cognitive problems associated with the disease.

But the science now says otherwise. A new study published in the journal Neurology says Gingko biloba does not improve cognitive performance in people with multiple sclerosis. The research was published in the Sept. 5, 2012, issue of Neurology, the medical journal of the American Academy of Neurology.

Obesity more common among rural residents than urban counterparts, study finds

KANSAS CITY, Kan.—A new study finds that Americans living in rural areas are more likely to be obese than city dwellers. Published in the National Rural Health Association's Fall 2012 Journal of Rural Health, the study indicates that residential location may play an important role in the obesity epidemic.

Cystic fibrosis patients of low SES are less likely to be accepted for lung transplant

Adult cystic fibrosis (CF) patients of low socioeconomic status (SES) have a greater chance of not being accepted for lung transplant after undergoing initial evaluation, according to a new study.

Charting the SH2 pool

New research published in BioMed Central's open access journal Cell Communication and Signaling describes a large set of interactions (interactome) which maps the range of phosphotyrosine (pTyr)-dependent interactions with SH2 domains underlying insulin (Ins), insulin-like growth factor-1 (IGF-1) and fibroblast growth factor (FGF) signaling pathways.

VisiGen is looking at you: Face genes identified

Monozygotic twins have almost identical faces and siblings usually have more similar faces than unrelated people, implying that genes play a major role in the appearance of the human face. However, almost nothing is known about the genes responsible for facial morphology in humans.

Scripps Research scientists reveal how deadly virus silences immune system

LA JOLLA, CA, September 13, 2012--Scientists at The Scripps Research Institute have determined the structure of a critical protein from the Marburg virus, a close cousin of Ebola virus. These viruses cause similar diseases and are some of the deadliest pathogens on the planet, each killing up to 90 percent of those infected.

Surviving without ice

With sea ice in the Arctic melting to record lows in summer months, marine animals living there face dramatic changes to their environment. Yet some crustaceans, previously thought to spend their entire lives on the underside of sea ice, were recently discovered to migrate deep underwater and follow ocean currents back to colder areas when ice disappears.

UMass Amherst chemists develop nose-like sensor array to 'smell' cancer diagnoses

AMHERST, Mass. – In the fight against cancer, knowing the enemy's exact identity is crucial for diagnosis and treatment, especially in metastatic cancers, those that spread between organs and tissues. Now chemists led by Vincent Rotello at the University of Massachusetts Amherst have developed a rapid, sensitive way to detect microscopic levels of many different metastatic cell types in living tissue. Findings appear in the current issue of the journal ACS Nano.

Warmer temperatures make new USDA plant zone map obsolete

Gardeners and landscapers may want to rethink their fall tree plantings. Warming temperatures have already made the U.S. Department of Agriculture's new cold-weather planting guidelines obsolete, according to Dr. Nir Krakauer, assistant professor of civil engineering in The City College of New York's Grove School of Engineering.

Rinderpest: New analysis shows how the world eradicated deadliest cattle plague

NAIROBI, KENYA (13 September 2012)—A new analysis published today in Science traces the recent global eradication of the deadliest of cattle diseases, crediting not only the development of a new, heat-resistant vaccine, but also the insight of local African herders, who guided scientists in deciding which animals to immunize and when.

Genes render some rice species sterile

Researchers have identified a set of three genes that are responsible for hybrid sterility in rice, or the inability of many hybrid rice species to pass their genes on to the next generation. These findings inform a model that suggests how such hybrid sterility is maintained across rice species, and they may lead to the genetic improvement of rice as a food stock.

The research is published in the 14 September issue of the journal Science, which is published by AAAS, the nonprofit science society.
