BLACKSBURG, Virginia, April 10, 2002 (ENS) - Flexible solar cells are one step closer to reality with the advent of one nanometer thick films developed by researchers at Virginia Tech.
The thin films can be changed from transparent to deep violet and back as fast as 20 times per second. By building up layers of the films, selected for their ability to self assemble and to convert light to electricity, the researchers are creating flexible photovoltaic devices, or solar cells.

Uncontrolled hunting and trade form the greatest threats to wildlife and wild lands in Asia, charges a group of experts from the Wildlife Conservation Society. The group, which held a workshop in Thailand's Khao Yai National Park last week, said long term studies show that current patterns of hunting and wildlife trade are not sustainable, and could drive wildlife to extinction.

The Earth's magnetic poles might be starting to flip say researchers who have seen strange anomalies in our planet's magnetic field.
The magnetic field is created by the flow of molten iron inside the Earth's core. These circulation patterns are affected by the planet's rotation, so the field normally aligns with the Earth's axis - forming the north and south poles.

NEW YORK (Reuters Health) - The substance that gives the spice turmeric its yellow color may help fight cancer, preliminary evidence suggests.
Researchers have found in the lab that the active ingredient in turmeric, called curcumin, can enhance the cancer-fighting power of treatment with TRAIL, a naturally occurring molecule that helps kill cancer cells. TRAIL stands for tumor necrosis factor-related apoptosis-inducing ligand.

SAN FRANCISCO (Reuters) - Final proof that dietary components like green tea, curry spice or wine can fight cancer in humans and not just laboratory test tubes remains elusive, but researchers are full of hope for the unconventional treatments.
"I believe that 50 years from now there will be a sub-specialty of medicine called cancer prevention doctors," Dr. Allan Conney, professor of cancer and leukemia at New Jersey's Rutgers University, said on Wednesday.
