Frequency of Atlantic hurricanes doubled over last century, climate change suspected
07-29-2007 · EurekAlert!
About twice as many Atlantic hurricanes form each year on average than a century ago, according to a new statistical analysis. The study concludes that warmer sea surface temperatures and altered wind patterns associated with global climate change are fueling much of the increase.

Common gene version optimizes thinking -- but with a possible downside
02-08-2007 · EurekAlert!
Most people inherit a version of a gene that optimizes their brain's thinking circuitry, yet also appears to increase risk for schizophrenia, a severe mental illness marked by impaired thinking. The seeming paradox emerged from the first study to explore the effects of variation in the human gene for a brain master switch, DARPP-32. The gene impacts the way two key brain regions exchange information, affecting a range of functions from general intelligence to attention.

How fish species suffer as a result of warmer waters
01-04-2007 · EurekAlert!
In order to estimate future changes, it is essential to develop a deeper understanding of the effect of water temperature on the biology of organisms under question. A new investigation, just published in the scientific journal Science, reveals that a warming induced deficiency in oxygen uptake and supply to tissues is the key factor limiting the stock size of a fish species under heat stress.

Sulfur dioxide may have helped maintain a warm early Mars
12-20-2007 · EurekAlert!
Sulfur dioxide (SO2) may have played a key role in the climate and geochemistry of early Mars, geoscientists at Harvard University and the Massachusetts Institute of Technology suggest in the Dec. 21 issue of the journal Science. Their hypothesis may resolve longstanding questions about evidence that the climate of the Red Planet was once much warmer than it is today.

First X-ray detection of a colliding-wind binary beyond Milky Way
02-16-2007 · EurekAlert!
Imagine two stars with winds so intense that they eject an Earth's worth of material roughly once every month. Next, imagine those two winds colliding head-on. Such titanic collisions produce multimillion-degree gas, which radiates brilliantly in X-rays. Astronomers have conclusively identified the X-rays from about two-dozen of these systems in our Milky Way. But they have never seen one outside our galaxy -- until now.

Campus energy answers blowing in the wind?
06-06-2007 · Massachusetts Institute of Technology (MIT)
A group of four students, blown away by MIT students' overwhelming support of wind power on campus, spent the spring determining whether the Institute should install rooftop wind turbines. They uncovered both good news and not-so-good news.

Recycling wind turbines
09-21-2007 · EurekAlert!
Wind power could become one of the greenest alternative energy resources we have, but only if replacement and recycling of windturbines is taken into account in assessing their environmental impact, say researchers.

Mercury's magnetosphere fends off the solar wind
01-30-2008 · EurekAlert!
The planet Mercury's magnetic field appears to be strong enough to fend off the harsh solar wind from most of its surface, according to data gathered in part by a University of Michigan instrument onboard NASA's Messenger spacecraft.

Female chimps keep the bullies at bay
03-07-2007 · EurekAlert!
Female chimpanzees may have found a fool-proof way to ensure they mate with only the highest ranking males, namely those with important social and physical characteristics that their offspring may inherit, according to a new study. Female chimpanzees do not synchronize their reproductive activities which reduces the opportunities for less-desirable males to coerce them into mating. The findings have just been published online in Springer's journal Behavioral Ecology and Sociobiology.
