Action video games sharpen vision 20 percent

...dapts to it. That learning carries over into other activities and possibly everyday life." The improvement was seen both in the part of the visual field where video game players typically play, but also beyond—the part of your vision beyond the monitor. The students' vision improved in the center and at the p...

2 brains -- 1 thought

...re inter-connected to a complex network. All brain activities are the result of the "firing" of nerve cells, when they send electrical pulses - like a Morse code - to other cells of the brain. This process depends on the exact dynamics of the neuronal activity. When the brain receives sensory input, calculates ...

Leeches ferry infection among newts

...ndings from the study may also indicate that human activities could lead to increases in the infection, since these leeches are most abundant in wetlands with lots of aquatic vegetation. The Penn State researchers say fertilizer-laden wastewater from farms and other sources often causes increased growth of ...

NIAID expands capability for influenza research and surveillance

...incipal investigator—Dr. Robert Webster) Research activities will involve evaluating antiviral drug regimens and factors that drive drug resistance; identifying viral markers that may indicate how a virus becomes deadly, adapts and transmits infection; uncovering immune system mechanisms that protect against t...

Uniform language for describing genes of pathogenic and beneficial microbes

... expansion of a lingua franca used to describe the activities of genes in living organisms. The expansion provides terms that scientists can use to describe the complex events that occur when a pathogenic or beneficial microbe encounters its host. Understanding these events is crucial for developing new interv...

Cornell lab confirms deadly fish virus spreading to new species

...ng equipment or live water wells in boats, boating activities and ballast water. "Basically, we don’t know how it got here, but it is here and it’s spreading," said Bowser. "It would be wonderful if we did know. However, I don’t think we ever will." The Great Lakes VHSV is not related to the European or Jap...

From the deep -- Researchers find new species of sea anemone

... and, more broadly, may provide clues on how human activities affect this unique, seemingly removed ecosystem. "The thing about these communities is that they seem so ephemeral and so unplanned," Daly said. "A whale dies where it dies, and its carcass lands wherever. But these are actually some of the most s...

Fat screen delivers plant-derived chemical with antidiabetic effects

...n vivo," Tontonoz's team concluded. The biological activities of harmine and TZDs underscore the fact that links between fat tissue and insulin resistance are complex and are likely to involve not only changes in fat tissue differentiation and cell number but also changes in the fat cells' function, they said. ...

New knowledge improves rice quality

...can take the new scientific knowledge generated by activities such as the recent sequencing of the rice genome, and use it to improve the lives of the poor by providing either better quality food or increased income." The quality rice network ?which was formed electronically in 2006 ?met for the first time l...

'Insulator' helps silence genes in dormant herpes virus

...showed that the insulator element blocked enhancer activities in the eye tissue of fruit flies and in human cells in culture. "Based on these findings, we were able to identify this element as a kind of chromatin insulator that helps HSV-1 maintain a balance in its life cycle." The study also showed that ...

Want to save polar bears? Follow the ice

... populations, and will inform important management activities such as designating protected areas for polar bears and their prey species." The first step of the new program will entail a workshop involving scientists, polar bear experts, and relevant organizations to provide input on the initial direction o...

First confirmed common genetic risk factors for breast cancer

...five genes code for proteins crucial to biological activities that previously had not been implicated as triggers of breast cancer. The genes carry the DNA recipes for proteins important to the growth and duplication of body cells and the signalling, or communications, that must occur between cells in order fo...

Runners -- Let thirst be your guide

...minantly afflicts exercisers engaging in endurance activities of 4 hours in duration or longer. But “the average...” of EAH have been reported from physical exercise activities as diverse as forced military marches, prolonged hiking and marathon, ultramarathon and triathlon ra...

Bacteria ferry nanoparticles into cells for early diagnosis, treatment

.... The sensors could make it possible to monitor activities inside a single cell for the early detection of cancer and other diseases and to monitor the progress of disease and response to drug therapy. The carbon nanotubes could be delivered into diseased cells and then exposed to light, causing them to heat...

Could fungal collection hold the key to new life-saving drugs?

...ew medicinal products. Previous work at SIDR found activities from plant extracts against diabetes, obesity and psoriasis. Professor Alan Harvey, Director of SIDR said: “We are delighted to be working with CABI and to have access to their fantastic source of fungal samples. We hope that this novel source ...

Massive herds of animals found to still exist in Southern Sudan

...ing observations of all wildlife, livestock, human activities and habitat. Observers on each side of the aircraft counted animals that they observed between two sets of rods placed on the wings of the plane. Using statistical techniques of extrapolation, they calculated estimates of how many animals there were ...

Undergraduate research shows leaderless honeybee organizing

...amentally confirm the hypothesis that major colony activities are initiated by the cumulative group actions of the colony’s older workers, not by the queen’s individual decision. What Pierce and colleagues found was that older workers gave signals to the queen and to the rest of the colony that it was time t...

Researchers find 24 species believed new to science in Suriname rainforest

...la crassicauda, feared extinct because gold mining activities had contaminated a creek where it was last seen more than 50 years ago. Overall, the survey recorded 467 species at the two sites, including large cats such as panther and puma, various monkeys, and a range of reptiles, amphibians, bats, birds, fi...
