California May Impose Strictest Pesticide Restrictions

September 26, 2014 2:00 pm | by Associated Press, Scott Smith | News | Comments

California farmers who spray a widely used insecticide on some of the state's most abundant crops may soon have to overcome the nation's steepest restrictions or find another pest killer, officials said this week. Regulators are proposing heavy restrictions— but not an all-out ban— on chlorpyrifos, used to treat crops like grapes and almonds.

Tonsil Stem Cells May Repair Liver Sans Surgery

September 24, 2014 2:00 pm | by ACS | News | Comments

The liver provides critical functions, such as ridding the body of toxins. Its failure can be deadly, and there are few options for fixing it. But, scientists are reporting a way to potentially inject stem cells from tonsils, a body part we don’t need, to repair damaged livers— all without surgery.

Why We Need Antibiotics

September 24, 2014 7:00 am | by ACS | Videos | Comments

Antibiotics revolutionized health care in the early 20th century, helping kill bacteria that once killed thousands of people. But bacteria are constantly outsmarting science, and new strains of antibiotic-resistant bacteria are popping up more frequently.
