(Image credit: Robin Dienel/Carnegie Institution for Science) Scientists have analyzed an unusually long blast of high-energy radiation, known as a gamma-ray burst (GRB), and determined that it originated from the collision of two ultradense neutron stars. And, importantly, this result helped the team observe a flash of light emanating from the same event that confirms these mergers are the sites that create...

President Jiang Zemin gets an update on China´s Terfenol-D project. The U.S. Navy spent millions of dollars to develop Terfenol-D in the early 1980s, and intelligence experts estimate that the People's Republic of China (PRC) has devoted extensive resources to try to steal it.
