Diet And Exercise Intervention Helps Older, Overweight Cancer Survivors Reduce Functional Decline (16/05/2009)
A home-based diet and exercise program reduced the rate of functional decline among older, overweight long-term survivors of colorectal, breast and prostate cancer, according to a new study.
"In 2008, the Centers for Medicare & Medicaid Services declared mobility maintenance and functional independence among at-risk older individuals as the sole priority in aging research. Older cancer survivors represent an important target because cancer and its treatment are associated with accelerated functional decline," the authors write.
Animals On Runways Can Cause Serious Problems At Small Airports (11/05/2009)
It is a bird. It is a plane. It is a potentially deadly combination.
A Purdue University study of 10 small Indiana airports found that animals can gain easy access to runways and infield areas, increasing the likelihood of planes striking those animals.
To make solar cells more efficient, sprinkle them with silver (07/04/2009)
MAKERS of solar cells face a dilemma. Purified silicon, the basic material of such cells, is expensive. The temptation, therefore, is to use less of it. As a result, the makers have developed a generation of cells whose silicon layers are only a micron or two deep, as opposed to the usual thickness of 200-300 microns. The thinner the cell, however, the less efficient it is. In particular, thin cells fail to capture much light at the red end of the spectrum. That means they produce up to 20% less electricity than standard cells of equivalent area. And that negates some of the advantage of their initial cheapness.
Nanotech Batteries For A New Energy Future (24/03/2009)
Researchers at the Maryland NanoCenter at the University of Maryland have developed new systems for storing electrical energy derived from alternative sources that are, in some cases, 10 times more efficient than what is commercially available
33% of Web Users Rely on the Same Password (12/03/2009)
A third of web users have admitted to using the same password for a number of different websites, says Sophos.
According to the security firm, just 19 percent never use the same password twice. Sophos added that three years ago, 41 percent of web users said they used the same password, indicating that just 8 percent of web users have realised the importance of strong, unique passwords
Wind, Water And Sun Beat Biofuels, Nuclear And Coal For Clean Energy (02/03/2009)
The best ways to improve energy security, mitigate global warming and reduce the number of deaths caused by air pollution are blowing in the wind and rippling in the water, not growing on prairies or glowing inside nuclear power plants, says Mark Z. Jacobson, a professor of civil and environmental engineering at Stanford.
Scientists find earliest evidence of animal life (05/02/2009)
Chemical traces left in 635 million-year-old rocks in Oman provide the earliest evidence so far of animal life, researchers said Wednesday.
