Popular Weed Killer is One Likely Cause of Cancer

March 23, 2015 8:17 am | by Associated Press, Joshua Goodman | News | Comments

The new labeling of the world's most-popular weed killer as a likely cause of cancer is raising more questions for an aerial spraying program in Colombia that is the cornerstone of the U.S.-backed war on drugs. A research arm of WHO has reclassified the herbicide glyphosate as a result of convincing evidence the chemical produces cancer in lab animals and more limited findings it causes non-Hodgkin's lymphoma in humans.

Special Microbes May Fight Obesity from the Gut

March 23, 2015 7:00 am | by ACS | News | Comments

Microbes may just be the next diet craze. Researchers have programmed bacteria to generate a molecule that, through normal metabolism, becomes a hunger-suppressing lipid. Mice that drank water laced with the programmed bacteria ate less, had lower body fat and staved off diabetes— even when fed a high-fat diet— offering a potential weight-loss strategy for humans.

Packing Peanuts May Soon Pack Energy

March 23, 2015 7:00 am | by ACS | Videos | Comments

They’re in just about every box you get in the mail, and they almost immediately get thrown in the trash. Now, one group of scientists wants to turn those packing peanuts into power. Researchers have shown how to convert waste-packing peanuts into high-performance carbon electrodes for rechargeable lithium-ion batteries that outperform conventional graphite electrodes, representing an environmentally friendly approach to reuse the waste.

Deadly Parasite is Tamed by Cousins

March 20, 2015 3:00 pm | by Burness Communications | News | Comments

African cattle infected with a lethal parasite that kills one million cows per year are less likely to die when co-infected with the parasite's milder cousin, according to a new study. The find suggests that "fighting fire with fire" is a strategy that might work against a range of parasitic diseases.

Study Questions Cause of Global Ice Age

March 20, 2015 3:00 pm | by Dartmouth College | News | Comments

A new international study casts doubt on the leading theory of what causes ice ages around the world— changes in the way the Earth orbits the sun. The researchers found that glacier movement in the Southern Hemisphere is influenced primarily by sea surface temperature and atmospheric carbon dioxide rather than changes in the Earth's orbit, which are thought to drive the advance and retreat of ice sheets in the Northern Hemisphere.
