Increased computer use by adolescents cause for concern
2011-04-26
Researchers at Queen's University have found a strong association between computer and Internet use in adolescents and engagement in multiple-risk behaviours (MRB), including illicit drug use, drunkenness and unprotected sex.
"This research is based on social cognitive theory, which suggests that seeing people engaged in a behaviour is a way of learning that behaviour," explains lead researcher Valerie Carson, a doctoral candidate in School of Kinesiology and Health Studies. "Since adolescents are exposed to considerable screen time—over 4.5 hours on average each day—they're ...

Snooze control: Fatigue, air traffic and safety
2011-04-26
It is safe to say that we are all guilty of these at some point in our day – stifling a yawn in the middle of the work day, eyelids growing heavy and having the strong urge for caffeine when 3pm rolls around. While most of us have experienced fatigue and lethargy on the job, spare a thought for those who hold the fate of people's lives in their hands.
In recent weeks, there have been reports of air traffic controllers falling asleep on the job, from Miami to Knoxville to Washington, DC. There is even speculation that staff shortage and a lack of attention may have contributed ...

MIT researchers use virus to improve solar-cell efficiency
2011-04-26
CAMBRIDGE, Mass. -- Researchers at MIT have found a way to make significant improvements to the power-conversion efficiency of solar cells by enlisting the services of tiny viruses to perform detailed assembly work at the microscopic level.
In a solar cell, sunlight hits a light-harvesting material, causing it to release electrons that can be harnessed to produce an electric current. The new MIT research, published online this week in the journal Nature Nanotechnology, is based on findings that carbon nanotubes — microscopic, hollow cylinders of pure carbon — can enhance ...
'Going off the grid' helps some bacteria hide from antibiotics
2011-04-26
COLLEGE STATION, Texas, April 25, 2011 - Call them the Jason Bournes of the bacteria world.
Going "off the grid," like rogue secret agents, some bacteria avoid antibiotic treatments by essentially shutting down and hiding until it's safe to come out again, says Thomas Wood, professor in the Artie McFerrin Department of Chemical Engineering at Texas A&M University.
This surreptitious and elaborate survival mechanism is explained in the online April edition of Nature Chemical Biology, which details the research of Wood and his post doctoral student Xiaoxue Wang along ...

Catastrophic amphibian declines have multiple causes, no simple solution
2011-04-26
CORVALLIS, Ore. – Amphibian declines around the world have forced many species to the brink of extinction, are much more complex than realized and have multiple causes that are still not fully understood, researchers conclude in a new report.
The search for a single causative factor is often missing the larger picture, they said, and approaches to address the crisis may fail if they don't consider the totality of causes – or could even make things worse.
No one issue can explain all of the population declines that are occurring at an unprecedented rate, and much faster ...
Study shows how mosquitoes handle the heat of a hot blood meal
2011-04-26
COLUMBUS, Ohio – Mosquitoes make proteins to help them handle the stressful spike in body temperature that's prompted by their hot blood meals, a new study has found.
The mosquito's eating pattern is inherently risky: Taking a blood meal involves finding warm-blooded hosts, avoiding detection, penetrating tough skin and evading any host immune response, not to mention the slap of a human hand.
Until now, the stress of the hot blood meal itself has been overlooked, researchers say.
Scientists have determined in female mosquitoes that the insects protect themselves ...
