How to manage forests in hurricane impact zones

...s and outcome risk (hurricane severity). "There really isn’t any way for managers to reduce the risk of a hurricane occurring or the severity of a hurricane when it hits," says Stanturf. "The long-term focus of managers should be on reducing the vulnerability of coastal ecosystems, particularly in those ...

Neural bottleneck found that thwarts multi-tasking

... brain," he continued. "These findings allow us to really now focus on this set of brain areas and to understand why these areas cannot process two tasks at once." The researchers are interested in further exploring what is happening in the bottleneck to slow performance and believe the work may have fut...

A steady, high-fat diet is bad, but the news gets worse

... milk, cereal bars and non-fat yogurt. "What’s really shocking is that this is just one meal," says Dr Tavis Campbell, a specialist in behavioural medicine and senior author of the study. "It’s been well documented that a high-fat diet leads to artherosclerosis and high blood pressure, and that exagg...

Bumblebee house warming -- it takes a village

...said. "We don't know whether the smaller bees are really better at warming the nest, or whether the larger bees avoid incubating for other reasons. In general, larger bumblebee workers are foragers for food and they could be committed to that task. This kind of size-based division of labor might make the...

Do you hear what i see?

...t what we used to call the ‘auditory cortex?should really be thought of as much more complex in terms of its response properties," says Robert Zatorre, PhD, head of the auditory cognitive neuroscience laboratory at McGill University. "The textbook-standard view of sensory systems as isolated from one anothe...

Study finds mercury prevalent in many western fish

...loading up on fish containing mercury and we don't really know at what levels they may be affected. In birds, the effects of mercury contamination are neurological or behavioral ?and often subtle. They may not clean their young, or they may leave eggs unattended in their nests. "We simply haven't done eno...

Killing the messenger RNA -- But which one?

...e gene. This was not anticipated ?it was something really new. "Looking more closely, we realized that the substitution we’d identified occurred in a particularly critical region of the molecule, the first 7 or 8 nucleotides ?out of a total of only 19 or 21 ?that define the molecule’s target specificity....

Circumcision: A proven strategy to prevent HIV

... became routine in sub-Saharan Africa. "This is really the first good news we've had in quite a long time. If we can reduce the risk of infection by such a substantial amount then we can save a lot of lives." In December the National Institutes of Health halted Bailey's trial of male circumcision afte...

Bacterial response to oxidation studied as toxin barometer

... have this response, but these particular bacteria really spew potassium,?said Love. And Rzigalinski was pleased to hear it. Perhaps the GGKE response could be used to predict potential damage to animal and human cells. “But bacteria are different from mammalian cells,?said Rzigalinski, who is focused on...

Smokers quit after damage to brain region

... smoking appears to rest on this platform. "It's really intriguing to think that disrupting this region breaks the pleasure feelings associated with smoking," said Damasio, director of the institute and holder of the David Dornsife Chair in Neuroscience at USC. "It is immediate. It's not that they smoke...

Fruit flies and global warming -- Some like it hot

"Yes," he says, with a boyish grin, "this is a fungus success story." For some, a fungus success story means nothing is growing at the back of their refrigerato...

Scientists reveal structure of gateways to gene control

... high-resolution map makes it very clear that they really are in exactly the same position. It's a remarkably consistent arrangement," Pugh said. The study also revealed that the nucleosomes at the transcription-promoter control centers occupy several overlapping positions on the DNA molecule, typically...

The only nerve cells in the body to run directly from the brain to the outside world, olfactory cells are under constant assault from harsh chemicals that one might happen to catch a whiff of by accident, risking damage or death.
