Researchers at Columbia University Medical Center have illuminated a window into how abnormalities in microRNAs, a family of molecules that regulate expression of numerous genes, may contribute to…

Ecosystems are constantly exchanging materials through the movement of air in the atmosphere, the flow of water in rivers and the migration of animals across the landscape. People, however, have also…

A whole generation of World War II soldiers endured the same trauma as soldiers in any war but for the most part kept quiet about it with little ill effect. Somewhere after that it became normal and…

MIT scientists say they have created a membrane, a mat of nanowires with the touch and feel of paper, that can absorb up to 20 times its weight in oil, and can be recycled many times for future use.…

Nautiloids are the sole surviving family of externally-shelled cephalopods that thrived in the tropical oceans 450–150 million years ago. However, in the intervening years their modern soft bodied…
