Warm weather brings on the seasonal meat favorites that are barbecued, grilled, broiled or fried. That also means more potential exposure to carcinogenic compounds known as heterocyclic amines (HCAs). There’s a way to reduce the risk significantly by just adding some spices — rosemary extracts or Thai spices.

World scientists have announced the agreement to construct a massive, comprehensive virtual observatory of historic importance for the study and monitoring of biodiversity at a planetary level — an online information system for life on Earth that will take its place alongside the world meteorology data network that pools information to predict the weather. The [...]
In what is believed to be the first US study designed to prevent anxiety disorders in the children of anxious parents, researchers have found that a family-based program reduced symptoms and the risk of developing an anxiety disorder among these children.

Researchers have demonstrated for the first time that injecting adult bone marrow stem cells into skeletal muscle can repair cardiac tissue, reversing heart failure.
When Chicago Blackhawk’s leading scorer Martin Havlat returned to the ice for game four of the Western Conference Final after sustaining a concussion only two days earlier, questions were raised surrounding his swift return. According to a new study, similar questions were raised by 25 percent of minor league hockey players who did not know [...]
In-growth and new generation of blood vessels, which must take place if a wound is to heal or a tumor is to grow, have been thought to occur through a branching and further growth of a vessel against a chemical gradient of growth factors. Now Swedish researchers have shown that mechanical forces are considerably more [...]
