New solution can help 'permanently get rid of germs' 6 July 2011Last updated at 11:45 By Katia Moskvitch Technology reporter, BBC News The solution does not wash away even after multiple hot laundry cycles, according to its inventor Dr Jason Locklin.
A new anti-microbial treatment that can make clothing - including smelly socks - permanently germ-free has been developed by US scientists. The spray-on solution can be applied to existing garments, according to the team from the University of Georgia. It is designed to offer low cost protection for healthcare facilities, such as hospitals. Chemical impregnated materials already exist, but have to be added during the manufacturing process. The new solution can be applied to natural and synthetic textiles including clothes, home carpets, shoes and even plastics. The inventor (centre) says the product can be useful in the medical field Many of these can cause disease, break down fabrics, create stains and produce odours. And the solution did not degrade even after multiple hot water laundry cycles.
ET Is sex good for your health—or is that just a fantasy? A flurry of small studies suggest that sex is as good for your health as vitamin D and broccoli. It not only relieves stress, improves sleep and burns calories, it can also reduce pain, ease depression, strengthen blood vessels, boost the immune system and lower the risk of prostate and breast cancer. But many of those studies rely on people to remember and report their sexual activity honestly and many can't distinguish between cause and effect. More research is needed to evaluate all these claims. Still, a look at what researchers do know about the physiology of sex shows that at least a few health benefits may come along with that roll in the hay. Some benefits of sex—beyond producing a baby, that is—are obvious even without scientific evidence. Much of that is due to chemistry—the rush of hormones and neurotransmitters that rise and fall during sexual activity. Not necessarily.

Interactive Java Tutorials Photosynthesis Green plants absorb water and carbon dioxide from the environment, and utilizing energy from the sun, turn these simple substances into glucose and oxygen.
With glucose as a basic building block, plants synthesize a number of complex carbon-based biochemicals used to grow and sustain life. This process is termed photosynthesis, and is the cornerstone of life on Earth. The tutorial demonstrates the basic molecular steps in the photosynthetic process. The tutorial initializes with water molecules being converted to molecular hydrogen and oxygen as a result of photon absorption in the granum. English chemist Joseph Priestley was the first investigator to find that plants release oxygen when they are healthy and growing. A key component to the understanding of photosynthesis was still missing until Dutch physiologist Jan Ingenhousz determined in 1778 that plants only absorb carbon dioxide and release oxygen when they are exposed to light.
