Using NASA's Chandra X-ray observatory, astronomers from the Harvard-Smithsonian Center for Astrophysics (CfA) and elsewhere have investigated an active galaxy known as Markarian 78. They report that the source exhibits termination ...
Materials Scientists at Duke University have developed a lightweight material that traps thermal energy when dry, but opens a series of tiny vents to let heat escape when a person starts sweating. The vents close again to ...

In a recent report, Xiaolei Peng and a team of scientists in materials science and engineering at the University of Texas, U.S., and the Tsinghua University, China, developed opto-thermoelectric microswimmers bioinspired ...
Physicists at MIT have designed a quantum "light squeezer" that reduces quantum noise in an incoming laser beam by 15 percent. It is the first system of its kind to work at room temperature, making it amenable to a compact, ...
