A research group led by Osaka University and Panasonic Corporation developed a method for making a prompt, exhaustive isolation of olfactory receptors (ORs) responding to the odorant of interest. This achievement will enable quick and easy exhaustive analysis of ORs responding to specific odorants, which previously required a great deal of time and effort. These results may be applied to biosensors capable of highly detecting only desired odorants.

New research published today in the journal Scientific Reports has revealed for the first time that half of the world's farmed fish have hearing loss due to a deformity of the earbone.

Like humans, fish have ears which are essential for hearing and balance, so the findings are significant for the welfare of farmed fish as well as the survival of captive-bred fish released into the wild for conservation purposes.

Electronic cigarettes have the potential to contribute to reducing death and disability caused by Britain's biggest killer, say experts in The BMJ today.

Reviewing a new report by the Royal College of Physicians (RCP) on the role of e-cigarettes in tobacco harm reduction, Professor John Britton and colleagues argue that e-cigarettes and other non-tobacco nicotine products "offer the potential to radically reduce harm from smoking in our society. This is an opportunity that should be managed, and taken."

There is widespread variation in the use of hip fracture surgery across England, Wales and Northern Ireland, concludes a study published by The BMJ today.

The findings show that, despite clear national guidelines, patients with higher levels of socioeconomic deprivation and those who require surgery at the weekend are less likely to receive it.

There are over 70,000 hip fractures in the United Kingdom every year, with a combined health and social cost of £2bn.

Researchers at McMaster University have found that a single minute of very intense exercise produces health benefits similar to longer, traditional endurance training.

The findings put to rest the common excuse for not getting in shape: there is not enough time.

"This is a very time-efficient workout strategy," says Martin Gibala, a professor of kinesiology at McMaster and lead author on the study. "Brief bursts of intense exercise are remarkably effective."

DALLAS - April 27, 2016 - Cardiologists at UT Southwestern Medical Center have found that sedentary behavior is associated with increased amounts of calcium deposits in heart arteries, which in turn is associated with a higher risk of heart attack.

Researchers at UT Southwestern have previously shown that excessive sitting is associated with reduced cardiorespiratory fitness and a higher risk of heart disease. The latest research - part of UT Southwestern's Dallas Heart Study - points to a likely mechanism by which sitting leads to heart disease.

Most people are aware of open-source computer programs. These free programs, accessible by anyone, spread technology to distant corners of the world. Cutting-edge innovations, however, come at a price. As a result, many software companies license their work.

These same concerns exist within the seed-development arena. Some plant researchers support the free exchange of new varieties of seeds and plants. Doing so, they argue, benefits both plant breeders and farmers. Considering seeds "intellectual property" may seem harmful to this free exchange of information.

Twenty-seven of 29 patients with an advanced type of leukemia that had proved resistant to multiple other forms of therapy went into remission after their T cells (disease-fighting immune cells) were genetically engineered to fight their cancers.

Coral reefs are widely known for their stunning array of color, shape and forms of life, making them a model for extreme biodiversity. Hidden within the multitude of reef inhabitants, but no less important, is their genetic diversity-- variability in DNA that gives species the capacity for adaptation, speciation and resilience in the face of stress. Research published today by a team of scientists from the University of Hawai'i at Mānoa (UHM) School of Ocean and Earth Science and Technology, the University of California, Santa Barbara (UCSB), University of St.

CHAMPAIGN, Ill. -- A culturally sensitive lifestyle intervention showed promise at motivating Latinas living in the U.S. to eat better and exercise more by connecting healthy-living behaviors with the lives of saints and prominent religious figures, new studies found.

Urologists at University of California, San Diego School of Medicine and Genesis Healthcare Partners have tested a new model of care for patients with low-risk prostate cancer. The evidence-based approach uses best practices to appropriately select and follow patients to avoid disease overtreatment. Results of the three-year study are now published online in the journal of Urology.

Society believes that those on social assistance - or welfare - should not be paying a premium to purchase ethical goods instead of cheaper alternatives, according to a new study from Simon Fraser University's Beedie School of Business.

Researchers found that consumers earning a moderate to high income who purchased ethical items, such as organic food, or environmentally friendly cars, were viewed as moral for doing so, while welfare recipients were judged immoral for making the exact same choice.

As male peacocks shake their long feathers in courtship, the iridescent eyespots remain nearly stationary and captivate females, according a study published April 27, 2016, in the open-access journal PLOS ONE by Roslyn Dakin from the University of British Columbia, Canada, and colleagues.

Whilst countries in the tropics and subtropics exhibit diverse patterns of seasonal flu activity, they can be grouped into eight geographical zones to optimise vaccine formulation and delivery timing, according to a study published April 27, 2016 in the open-access journal PLOS ONE by Siddhivinayak Hirve from the World Health Organization, Geneva, Switzerland, and colleagues.

When fluctuating climates in the Ice Age altered habitats, modern humans may have adapted their diets in a different way than Neandertals, according to a study published April 27, 2016 in the open-access journal PLOS ONE by Sireen El Zaatari of the University of Tübingen, Germany, and colleagues.
