Solar Thermal Building Product Demonstrates Energy Savings Of 48 Per C Researchers at the Alberta Research Council Inc. (ARC) have completed a pilot study identifying a more efficient technology to insulate homes, reducing space heating costs for homeowners. Researchers proved by combining direct solar collection and heat storage technology with existing structural insulated panel system (SIPS), energy consumption for space heating could be reduced by 48 per cent. Discovery May Lead To Precision Engineering Of Superconducting Thin Fi Using precision techniques for making superconducting thin films layer-by-layer, physicists have identified a single layer responsible for one such material's ability to become superconducting, i.e., carry electrical current with no energy loss. The technique could be used to engineer ultrathin films with "tunable" superconductivity for higher-efficiency electronic devices. The Seoul of a New Machine Korean robotics researchers develop ghostly software agents that move from one droid to another, taking possession of their mechanical bodies long enough to perform a task, before vanishing into the ether. Quinn Norton reports from Daejeon, Korea. Hurricane Katrina: Links to Health Information including Toxicology an Dozens of links to high-quality information about hazardous materials, environmental cleanup and recovery, pests, drinking water, food safety, mold, farming and agriculture, animal rescue, and specific chemicals. Some information also available in Spanish. From the Specialized Information Services Division of the National Library of Medicine. Mayo Clinic Researchers Create 'Obedient Virus'; First Step To Use Mea An international team of Mayo Clinic-led researchers is first to devise a system that consistently converts the measles virus into a therapeutic killer that hunts down and destroys cancer cells -- and cancer cells only. Their research findings appear as an advanced electronic article of Nature Biotechnology. Thyroid-cancer Test Reveals Recurrence Early A blood test for thyroid cancer can detect persistent or recurrent disease even before doctors can find any trace of a tumor, according to a new study. The findings suggest that people treated for the disease should be examined regularly for early signs of recurrence. The study examined how well a test for thyroid cancer can predict whether the disease will recur. Erectile Dysfunction: Group Psychotherapy Can Help Taking part in group psychotherapy can help men who have erectile dysfunction to overcome their problem, and adding sildenafil to group therapy was more effective that sildenafil alone. In addition, group psychotherapy was more effective than taking sildenafil on its own, a Cochrane systematic review has found. Marijuana Smoke Contains Higher Levels Of Certain Toxins Than Tobacco Here's another reason to "keep off the grass."Researchers report that marijuana smoke contains significantly higher levels of several toxic compounds -- including ammonia and hydrogen cyanide -- than tobacco smoke and may therefore pose similar health risks. The scientists found that ammonia levels were 20 times higher in the marijuana smoke than in the tobacco smoke, while hydrogen cyanide, nitric oxide and certain aromatic amines occurred at levels 3-5 times higher in the marijuana smoke, they say. Cell Phones Freed! Poor Suffer? Your legal columnist wins an exemption to the DMCA for consumers who digitally unlock their cell phones to use with other carriers. But now a wireless giant says the new rule will damage the prepaid cell phone industry, and hurt those who can't afford monthly service. Commentary by Jennifer Granick. Blood Clots: A Novel Molecular Dictator 'With A Conscience'Discovered Researchers have uncovered an important naturally occurring mechanism in the body where "bad"cells that cause blockages in our blood vessels are kept under strict growth control, while "good"cells that keep our blood vessels free of clots and growths are left unaffected.
