SAN FRANCISCO, Sept. 6, 2012 -- After last year's accidental discovery of "zombie"-like bees infected with a fly parasite, SF State researchers are conducting an elaborate experiment to learn more about the plight of the honey bees.

To really understand the mundane world we live in we must also understand matter at the edge of the nuclear landscape.

Computational researchers have contributed to this understanding with an intensive simulation of the short-lived oxygen-23 isotope. Working with colleagues at the University of Tennessee and the University of Oslo in Norway, the team helped overturn a decade-old misconception about how this isotope is put together.

Their work is discussed in a recent edition of the journal Physical Review C.

ENERGY – Revolutionary heat pump . . .

Montreal, September 6, 2012 – Can a computer "read" an online blog and understand it? Several Concordia computer scientists are helping to get closer to that goal.

Pollinating insects contribute to agricultural production in 150 (84%) European crops. These crops depend partly or entirely upon insects for their pollination and yield. The value of insect pollinators is estimated to be €22 billion a year in Europe. Declines in managed pollinators, such as honeybees, and wild pollinator such bumblebees, solitary bees and hoverflies, are therefore of growing concern as we need to protect food production and the maintain wildflower diversity.

RICHLAND, Wash. – Today's light-emitting diode light bulbs have a slight environmental edge over compact fluorescent lamps. And that gap is expected to grow significantly as technology and manufacturing methods improve in the next five years, according to a new report from the Department of Energy's Pacific Northwest National Laboratory and UK-based N14 Energy Limited.

London, UK (05 September 2012) – In 'Censors on Campus', Index on Censorship asks whether lives might be saved by making vital research freely available. As malaria expert Bart Knols argues, in some parts of Asia and Africa the fight against malaria is severely hampered because doctors and researchers are denied full access to the 3,000 articles published on the disease each year. At the same time, scientists living and working in developing countries are prevented from becoming global players in the public health arena.

A by-product of biofuel manufacture can power microbial fuel cells to generate electricity cheaply and efficiently, according to scientists presenting their work at the Society for General Microbiology's Autumn Conference. The work could help develop self-powered devices that would depollute waste water and be used to survey weather in extreme environments.

COLUMBUS, Ohio – New research suggests that violent video games may not make players more aggressive – if they play cooperatively with other people.

In two studies, researchers found that college students who teamed up to play violent video games later showed more cooperative behavior, and sometimes less signs of aggression, than students who played the games competitively.

HOUSTON – (Sept. 4, 2012) – Researchers at Rice University and the Université catholique de Louvain, Belgium, have developed a way to make flexible components for rechargeable lithium-ion (LI) batteries from discarded silicon.

The Rice lab of materials scientist Pulickel Ajayan created forests of nanowires from high-value but hard-to-recycle silicon. Silicon absorbs 10 times more lithium than the carbon commonly used in LI batteries, but because it expands and contracts as it charges and discharges, it breaks down quickly.

The main cause of cyanide poisoning is smoke inhalation in closed spaces during fires. Cyanides, the salts of hydrocyanic acid, inhibit cellular respiration and may lead to coma or death. The rapid administration of a cyanide antidote is essential for successful treatment. Previously, detecting cyanide in the blood took up to an hour and could only be performed in the laboratory, a lengthy process that is poorly suited for emergency situations. As a result, emergency doctors and paramedics are forced to administer antidotes based solely on presumptive diagnoses.

Many studies report trends in clinical outcomes of persons receiving HIV care in the U.S., but few have been specifically designed to be nationally representative. This is an important distinction as researchers strive to continue to make improvements in care and outcomes for all people living with HIV in the U.S. NA-ACCORD (North American AIDS Cohort Collaboration on Research and Design) is the largest cohort of HIV-infected adults in North America, with more than 100,000 patients enrolled.

Between 2000 and 2008, the proportion of HIV-infected patients in the U.S. receiving effective treatment known as highly active antiretroviral therapy (HAART) increased, and HIV-infected patients appeared to be less infectious and have healthier immune systems at death, according to a study led by researchers at the Johns Hopkins Bloomberg School of Public Health. The study was nested in the NA-ACCORD (North American AIDS Cohort Collaboration on Research and Design), which is the largest cohort of HIV-infected adults in North America.

Digested coconut oil is able to attack the bacteria that cause tooth decay. It is a natural antibiotic that could be incorporated into commercial dental care products, say scientists presenting their work at the Society for General Microbiology's Autumn Conference at the University of Warwick.

'Bioplastics' that are naturally synthesized by microbes could be made commercially viable by using waste cooking oil as a starting material. This would reduce environmental contamination and also give high-quality plastics suitable for medical implants, according to scientists presenting their work at the Society for General Microbiology's Autumn Conference at the University of Warwick.

Taking a fall in older life can not only result in injury, but also a potentially debilitating loss of confidence. But new guidelines for physiotherapists, co-compiled by a leading academic in the field from the Peninsula College of Medicine and Dentistry (PCMD), University of Exeter, aim to refresh out-dated guidelines and introduce better direction for physiotherapists who work with elderly people at risk of falling.
