Astronomers have just assembled one of the most comprehensive portraits yet of the universe’s evolutionary history.
To find 25,000 participants to enroll in all the approved trials, researchers would have to begin by approaching more than 37 million people with early memory loss.
Weeks of dry, hot weather have exposed the outlines of several archeological sites across the U.K., dating back thousands of years. Drier soil conditions have allowed archeologists to capture aerial photographs of previously hidden features from ancient times, to reveal farms, burial monuments, ditches, walls and vegetation patterns, or cropmarks.

Sequencing the wheat genome – once considered by scientists to be an insurmountable task – has been achieved through a worldwide collaboration of researchers spanning 13 years. On Friday the International Wheat Genome Sequencing Consortium (IWGSC) published a detailed description of the genome of bread wheat in the journal Science.
A potential treatment for sudden liver failure could cut the need for transplants, say scientists at the University of Edinburgh. The liver has an incredible natural ability to repair itself, but this can be lost in some injuries including severe drug overdoses. The therapy is a cancer drug that restores this regenerative potential.
