How to manage forests in hurricane impact zones

...ver 5.5 million acres of timberland in the coastal states of Texas, Louisiana, Mississippi, and Alabama affected. Using available data on the damage from these storms, the researchers constructed an adaptive strategy that distinguishes event risk (hurricane occurrence) from the vulnerability of coastal fore...

Neural bottleneck found that thwarts multi-tasking

...The research is particularly timely, as additional states consider banning the use of cell phones while driving. "While we are driving, we are bombarded with visual information. We might also be talking to passengers or talking on the phone," Marois said. "Our new research offers neurological evidence t...

Scientists map air pollution using corn grown in US fields

...ollution from California and other western coastal states to drift east, but they found that the Rocky Mountains appeared to provide a barrier for the movement of carbon dioxide from fossil fuels. Air in the Mountain West, including Colorado, Idaho and New Mexico, was the cleanest, with about 370 pa...

Lower carbon dioxide emissions from coal-fueled power plants possible with technology development

...andstone formations common in Texas and some other states are already being considered nationally for this type of storage. Colleagues at the Jackson School’s Bureau of Economic Geology will also study this storage option at the bureau’s Gulf Coast Carbon Center. They will evaluate using this liquid carb...

Study finds mercury prevalent in many western fish

...he prevalence of the element throughout 12 western states caught the researchers somewhat by surprise. "Mercury is everywhere," said Alan Herlihy, a research associate professor with OSU's Department of Fisheries and Wildlife and one of the authors of the study. "It was literally in every fish we sampled...

'The eyes have it' -- Autism research yields surprising results

...thought to be poor at interpreting people’s mental states based on facial expressions, especially expression...at autistic children were able to interpret mental states when looking at animated facial expressions. The findings also suggest that the use of moving images...

Widely used hepatitis B drug spurs HIV drug resistance

...untreated. The drug's label information currently states that is has no clinical effects on HIV. According to Thio, some co-infected patients decide first to treat their hepatitis B infection if HIV has not yet weakened their immune system and to avoid the debilitating side effects of anti-HIV medicati...

Increase in drug development for killer diseases is not enough

...ntellectual property management are lacking. Eiss states that there is a "need to develop and promote forms of intellectual property management and technology transfer practice that help ensure access for the poor through the strategic use of such tools as price tiering and market segmentation, and the eng...

Cities change the songs of birds

...known as the acoustic-adaptation hypothesis, which states that some aspects of the vocal variety of animal communication sounds are shaped by the environment. The authors point out that song divergence within a species as a result of such “environmental shaping?could potentially play a crucial role in the p...

Learning during sleep?

...olidation theory as the best approach so far. This states that fresh impressions are first stored as short-term memories in the hippocampus. They are then said to move within hours or a few days - usually during deep sleep - into the cerebral cortex where they enter long-term memory. Investigations by Thoma...

Engineered yeast speeds ethanol production

...hich is 85 percent ethanol, are becoming common in states where corn is plentiful; however, their use is mainly confined to the Midwest because corn supplies are limited and ethanol production technology is not yet efficient enough. Boosting efficiency has been an elusive goal, but the researchers, led b...

Stroke symptoms common among general population

In telephone interviews, participants provided information about demographics, general quality of life and medical history, including whether a physician had ever told them they had a stroke and whether they had exper...

Biologists probe the machinery of cellular protein factories

...t goal is to trap the ribosome in other functional states to get more frames of the movie," he said. The authors of the paper, in addition to Noller, are postdoctoral researcher Andrei Korostelev, senior scientist Sergei Trakhanov, and postdoctoral researcher Martin Laurberg. The researchers used a techni...

Newly discovered behavior in cancer cells signals dangerous metastasis

... of how cancer cells shift between two alternating states -- travelers and nesters -- represents a new understanding of how cancer metastasizes, or spreads to other parts of the body, said the Duke Comprehensive Cancer Center researchers who conducted the study. "Understanding this toggle switch might ulti...

Study finds the air rich with bacteria

...ry common. Tularemia has been reported in all U.S. states except Hawaii. This natural background can confound the detection of a terrorist attack and trigger false alarms. The trick is to determine whether the amount of F. tularensis detected in an air sample is in synch with normal levels, or if it's suspi...

A simple feedback resistor switch keeps latent HIV from awakening

As well as being used as medicine transporters, conceivable applications include using the capsules as a component of car paint which releas...

Obesity levels in US are grossly underestimated

Boston, MA ?The prevalence of obesity in the U.S. states has been greatly underestimated. Researchers at th... concluded that estimates of obesity in individual states have been too low, by more than 50%. Their study, which corrects for misreporting in those surveys, ...

New mechanism explains glucose effect on wakefulness

Where we change our mind

...other was a set of "operant" states. These operant states were a "proceed or update mode" or a "reevaluate or back-track mode." Analyzing the brain regions active during these states, Yoshidi and Ishii pinpointed which regions of the subjects' cerebral cortex were active during the different processes invo...
