Findings published in this months issue of Clinical Cancer Research and featured on the journals cover, may bring researchers one-step closer to the development of tumor markers to detect colon cancer early, before it has had a chance to spread and when it is easier to cure, say researchers from the University of Pittsburgh Cancer Institute (UPCI). These tumor markers – elevated levels of proteins or other substances in the blood, urine or tissue that indicate the presence of cancer – als
Too few financial companies including banks, pension funds and insurance companies are taking the risks and opportunities posed by climate change seriously, members of the United Nations Environment Programme`s (UNEP) Finance Initiatives are warning.
Losses as a result of natural disasters appear to be doubling every decade and have reached one trillion US dollars in the past 15 years. Annual losses, in the next ten years, will reach close to $150 billion if current trends continue.

The art of walking through walls made real
Walking through walls has just become possible. Senior researcher Ismo Rakkolainen and Professor Karri Palovuori from Tampere University of Technology have pioneered a fog display that is physically penetrable. A prototype of the screen was introduced to the public for the first time at the Academy of Finland stand at the Turku Science Exhibition on 4-6 October 2002. International
Researchers have conducted the most definitive study of its kind to show that sleeping on the stomach increases the risk of U.S. infants for Sudden Infant Death Syndrome (SIDS). Previously, researchers had relied largely on overseas studies for making the recommendation that infants be placed on the back to sleep in order to reduce their risk for SIDS.
The study focused primarily on SIDS cases among African Americans, a group at roughly twice the risk for SIDS than are Caucasians. The findin
But new study sheds light on what makes leaves turn red
Groundhog behavior is supposedly a harbinger of spring.
Wooly Bear Caterpillars are a possible portent of the severity of winter.
But who knows when the Vermont forests will blaze with autumnal gold, orange and scarlet?
Not the weather forecasters, not the almanacs, not some octogenarian recluse Vermonter. Leave that to the scientists.
Here in Vermont where one out of four of the forests
Scientists are beginning to change their thinking about why the immune systems of most people infected with HIV cannot control the spread of the virus while the immune systems of a rare group of individuals, called long-term nonprogressors, can. For some time, scientists thought that people who could not control HIV had too few HIV-fighting white blood cells called CD8+ T cells. However, a new study suggests the difference is not the number but the quality of these cells: both nonprogressors and othe
