Physical Activity May Hasten Build-Up of Heart Attack Risk Factor

Heart Attack Illustration

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

Tetranuclear Rare Earth Metal Complexes With Giant Spin

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

Deadwood Releasing 10.9 Gigatons of Carbon Every Year – More Than All Fossil Fuel Emissions Combined

Deadwood Forest

Credit: Australian National University Decaying wood releases around 10.9 gigatons of carbon worldwide every year, according to a new study by an international team of scientists. This is roughly equivalent to 115 percent of fossil fuel emissions. Co-author of the study Professor David Lindenmayer from The Australian National University (ANU) says it’s the first time … Read more

New Medicine Shows Promise in Treating Early-Stage Breast Cancer
