Common Lab Dye Is a Wonder Drug – for Worms

Basic Yellow 1, a dye used in neuroscience labs around the world, is a wonder drug for nematode worms. Thioflavin T extended lifespan in healthy worms by more than 50 percent and slowed the disease process in worms bred to mimic aspects of Alzheimer’s. The research could open new ways to intervene in aging and age-related disease.

International Food Information Council Provides Common Sense Context to FDA Hearing on Food Colors

In comments submitted to the U.S. Food & Drug Administration (FDA) in advance of today’s hearing on food colors and hyperactivity in children, the International Food Information Council (IFIC) highlighted the lack of sound scientific evidence that links food colors and hyperactivity and provided consumer insights that show a low level of concern by the majority of Americans about food colors in the foods they purchase and consume.

Risk for New England Floods Rises with Water Tables

As spring flood season comes to New England, a new study suggests that soil moisture and the water table have been rising over the past 10 years across the region, and we may be facing a higher risk of flooding in the years ahead, due to changes in subsurface water storage over the longer term.

Safer, More Effective Skin-Whitening Creams from Ancient Chinese Herbal Medicine

Scientists have identified ingredients in an herb used in traditional Chinese medicine that show promise as a safer, more effective alternative to current skin-whitening cosmetics, which can cause problems ranging from allergic reactions to skin cancer. The finding could be a boon to women in Asian countries, where skin-whitening is a common beauty practice. Scientists will describe the new method and materials at the 241st National Meeting of the American Chemical Society in Anaheim.
