Linked to calcium deposits in coronary arteries, used to measure cardiovascular disease risk But findings don’t outweigh numerous health benefits of exercise, emphasize researchers. Physical activity may paradoxically hasten the build-up of calcium deposits (plaque) in the coronary arteries, the amount of which is used to assess future cardiovascular disease risk, finds research published online … Read more
Credit: Angewandte Chemie Magnets formed from a single molecule are of particular interest in data storage, since the ability to store a bit on every molecule could vastly increase the storage capacity of computers. Researchers have now developed a new molecular system with a particular magnetic hardness. The ingredients in this special recipe are rare … Read more
