Experts present new research on hot topics in aging at GSA's annual meeting in Washington, DC
... serious health priority. Ideally, retirement from driving should occur as close to the optimal time as possible, neither too early, nor too late. Drivers with dementing illnesses often do not recognize that they are unsafe, fail to make needed modifications, and are at greatly increased risk for accidents. ...Single genetic defect links many risk factors for heart disease and stroke
... there hasn't been a clear understanding of what's driving this relationship." Various combinations of these abnormalities affect up to a quarter of the U. S. population, and they are contributing to a public health epidemic of heart disease and stroke. Lifton said that one woman with hypertension and low ...Cars, not crops, should be chief targets in reducing greenhouse gases
...issions as you might with simple technologies like driving hybrid cars that get twice the mileage. "Taking a third of our crop land out of production and using it to sequester carbon would mean very high prices for food in this country and a lot of hungry people around the world," Schlesinger sai...UK scientist and children's author wins EMBO Award for Communications 2004

...evidently impacting not only local people but also driving a region-wide collapse of biodiversity, it seems questionable that foreign governments should be using their taxpayers' money to subsidize the mining of developing countries' fish stocks," said Balmford.

The same balance between energy and entropy, which measures disorder, governs the force distributions in random materials; though the linking quantity between energy and entropy in r...Study links ozone, mortality in urban areas

Bell said by driving less, taking public transportation, reducing energy consumption and staying indoors on hot days when the ozone level is high would lessen ozone-related mortality and improve the health of people who suffer from respiratory illness.......se neurons provide the fly with an internal clock, driving circadian rhythms of behavior even in the absence of light. While Lmo is found throughout the body, it is enriched in the brain. By expressing normal Lmo in over-sensitive mutants, the researchers discovered that Lmo's cocaine-related effects were lo...This is your fly's brain on drugs
...vs), which provide the fly with an internal clock, driving circadian activities even in the absence of light. However, it appears that these neurons modulate cocaine sensitivity independently of their role in controlling circadian rhythms. Because Lmo -related proteins are found in key areas of mammal...How city dwellers and living things put the green into our urban open spaces

Thus, an assessment of numbers of prey, such as deer and wild boar that tigers depend upon, is also built into the survey design.

...aid the idea of looking at summer temperature as a driving factor in declining reindeer populations is important and controversial. Biologists have linked declines in animal populations to a combination of changing climate and vegetation, increased rainfall and even insect harassment. He admits that there ...Study identifies key aspect of immune response against HIV
...ue of Nature also describes how HIV infection is driving human evolution, since individuals with protective versions of the identified genes are more likely to survive and pass those genes along to children. Including researchers from the University of Oxford and the University of KwaZulu-Natal in South A...Research points to new theory driving evolutionary changes
... mutations in the genetic code are responsible for driving evolutionary changes in species. One widely accepted hypothesis is that random, so-called single-point mutations - a change from one letter to another among the billions of letters contained in the code - minutely but inexorably change an organism's ...Study in Royal Society journal on first evidence for magnetic field detection in sharks

Dr J Arendt and Professor DN Reznick Two factors driving evolution in guppies are predation (some populations have large predators that eat guppies of all size, some have small predators that only eat small guppies) and food level. We compared guppies taken from high predation and low predation to determi......o percent for males, respectively.
