Illuminating neuron activity in 3-D: New technique lets scientists monitor small worm's entire nervous system

Posted: 18 May 2014 01:44 PM PDT

Researchers have created an imaging system that reveals neural activity throughout the brains of living animals. This technique, the first that can generate 3-D movies of entire brains at the millisecond timescale, could help scientists discover how neuronal networks process sensory information and generate behavior.

Windshield washer fluid a source of Legionnaires: Found in most school buses

Posted: 18 May 2014 01:44 PM PDT

A form of bacteria responsible for respiratory illness, including the deadly pneumonia known as Legionnaire's disease, may be able to grow in windshield washer fluid and was isolated from nearly 75 percent of school buses tested in one district in Arizona, according to new research.

Bacteria in mouth may diagnose pancreatic cancer

Posted: 18 May 2014 01:44 PM PDT

Patients with pancreatic cancer have a different and distinct profile of specific bacteria in their saliva compared to healthy controls and even patients with other cancers or pancreatic diseases, according to new research. These findings could form the basis for a test to diagnose the disease in its early stages.

Study debunks common myth that urine is sterile: Bacterial differences found in urine of healthy women and women with overactive bladder

Posted: 18 May 2014 01:43 PM PDT

Bacteria live in the bladders of healthy women, discrediting the common belief that normal urine is sterile. This study also revealed that bladder bacteria in healthy women differ from the bladder bacteria in women affected by overactive bladder, which causes a sudden need to urinate.

Scientists discover how to turn light into matter after 80-year quest

Posted: 18 May 2014 01:42 PM PDT

Physicists have discovered how to create matter from light -- a feat thought impossible when the idea was first theorized 80 years ago. In just one day over several cups of coffee in a tiny office, three physicists worked out a relatively simple way to physically prove a theory first devised by scientists Breit and Wheeler in 1934. Breit and Wheeler suggested that it should be possible to turn light into matter by smashing together only two particles of light (photons), to create an electron and a positron -- the simplest method of turning light into matter ever predicted. The calculation was found to be theoretically sound, but Breit and Wheeler said that they never expected anybody to physically demonstrate their prediction.

Heart failure hospitalization more than doubles in IBD flares

Posted: 18 May 2014 06:27 AM PDT

Heart failure hospitalization more than doubles during inflammatory bowel disease (IBD) flares, according to a study of more than 5 million people. "We found that patients with new-onset IBD had a 37% increased risk of hospitalization for heart failure during a mean follow-up of 6.4 years compared to the healthy population. But the risk more than doubled during periods of IBD activity," a researcher noted.

Scientists create synthetic duplicates of spiders' super-sticky, silk 'attachment discs'

Posted: 16 May 2014 05:33 PM PDT

Researchers are again spinning inspiration from spider silk -- this time to create more efficient and stronger commercial and biomedical adhesives that could, for example, potentially attach tendons to bones or bind fractures. The scientists created synthetic duplicates of the super-sticky, silk "attachment discs" that spiders use to attach their webs to surfaces.

Breakthrough in HIV/AIDS research gives hope for improved drug therapy

Posted: 16 May 2014 05:32 PM PDT

The first direct proof of a long-suspected cause of multiple HIV-related health complications was recently obtained by a team of researchers. The finding supports complementary therapies to antiretroviral drugs to significantly slow HIV progression. The study found that a drug commonly given to patients receiving kidney dialysis significantly diminishes the levels of bacteria that escape from the gut and reduces health complications in non-human primates infected with the simian form of HIV.

MicroRNA that could be used to suppress prostate cancer progression found

Posted: 16 May 2014 05:32 PM PDT

About one in seven men will develop prostate cancer over the course of a lifetime, and about one in 36 men will die from it. This is why findings by researchers, showing that a tumor suppressive microRNA, when activated by an anti-estrogen drug, could contribute to development of future targeted therapies, are important.

New early warning system predicts dengue fever risk during the football World Cup in Brazil

Posted: 16 May 2014 05:29 PM PDT

For the first time, scientists have developed an early warning system to predict the risk of dengue infections for the 553 microregions of Brazil during the football World Cup. The estimates show that the chance of a dengue outbreak is enough of a possibility to warrant a high-alert warning in the three northeastern venues (Natal, Fortaleza, and Recife) but is likely to be generally low in all 12 host cities.

Many Smokers Still Surprised by Facts About Tobacco's Dangers

Posted: 15 May 2014 12:38 PM PDT

Between half and one-third of smokers presented with corrective statements about the dangers of smoking indicated that some of the information was new to them and motivated them to quit, finds a new study. "The tobacco industry systematically deceived the public for decades, denying that smoking was dangerous or addictive," explained one of the study's authors, adding that cigarette makers were actually designing their products to be more addictive to increase sales.
