Study examines calorie restriction and glycemic load

...CA and first author of the study. "However, we did detect a greater tendency for weight and body-fat regain among LG participants. This finding suggests that reduced calorie intake may be harder to sustain on LG diets over time." The LG diet contained 40 percent carbohydrate, 30 percent fat, and 30 percen...

MIT model helps researchers 'see' brain development

A native of the Seychelles islands in the Indian Ocean, D. sechellia split from its sister spe...

Genomic test could help detect radioactivity exposure from terrorist attacks

... Center have developed a new blood test to rapidly detect levels of radiation exposure so that potentially life-saving treatments could be administered to the people who need them most. There appears to be a critical window of 48 to 72 hours for administering treatments aimed at halting the devastating ef...

Detecting poisons in nectar is an odour-ous task for honeybees

...think that perhaps honeybees had a reduced need to detect and learn about toxins, despite the fact that some floral nectar contains toxins. Work carried out by Dr Wright and colleagues suggests that honeybees may have the ability to react to toxins, even if they cannot taste them. Researchers found that ...
