An Ichthyologist from The Academy of Natural Sciences has discovered a fish that is new to science from the coastal waters off New Zealand. This exciting new find is a species of Chimaera, an ancient deep-sea relative of sharks found in all the world's oceans. These fishes evolved 400 million years ago and are one of the oldest fish species alive today.
A University of Iowa research team has developed a way to isolate replicating deoxyribonucleic acid (DNA) molecules that scientists then can use to examine the replication process under controlled conditions.
A low-calorie diet slows the progress of prostate cancer in animals, new research at Ohio State shows. The slowing of tumor progression occurred whether the calories were reduced by cutting fat, carbohydrates, or the overall diet.
