Antarctic glacier thinning at alarming rate

The Pine Island Glacier in West Antarctica is losing ice four times as fast as it was a decade ago, with scientists estimating that the main section of the glacier will disappear in just 100 years. The glacier's acceleration is attributed to warming oceans and has significant implications for global sea level rise.

Studies do not support unhealthful relation between animal foods and breast cancer

Recent studies published by the American Society for Nutrition provide no evidence that consuming animal foods increases breast cancer risk. In fact, researchers suggest that moderate and mindful consumption of these foods can be important in attaining optimal nutrition, particularly for women who may not consume enough iron and calcium.
