Right breakfast bread keeps blood sugar in check all day

If you eat the right grains for breakfast, such as whole-grain barley or rye, the regulation of your blood sugar is facilitated after breakfast, lunch, and dinner. It was previously not known that certain whole-grain products have this effect all day. This is due to a combination of low GI (glycem...

Corals that can fight global warming may one day help fragile reefs

While humans can survive large temperature fluctuations, such species as corals are only comfortable within a 12-degree temperature range. And rising global temperatures appear to be threatening their survival, according to Drew Harvell, Cornell professor of ecology and evolutionary biology. Howe...

Woman's Day and For Womens of Science
