Another important discovery may give women a new way to control their fertility without unwanted, harmful side effects. Because the eggs could not mature, they could not be fertilized. Future work will attempt to translate this advance into a product that will give women new opportunities to have children when they are wanted. This evidence allows women to choose epidural anesthesia for delivery without fear that it may increase their chance of cesarean section. This prototype hand works by sensing the user s muscular contractions and moving the mechanical fingers in response.
Early testing shows that the device is sensitive enough to permit limited piano playing.
One of the more exciting research discoveries involved new cloning techniques. In the first accomplishment of its kind, scientists have demonstrated that cloning mammals from adult cells could be accomplished repeatedly in mice. This extraordinary advance will enable researchers to answer many basic questions about how cells are programmed during normal and abnormal development. These newest cloning techniques can have a variety of applications. They can improve the breeds of livestock, eventually help derive therapeutic products, and may also help preserve rare and endangered species.
