Robotic Insects Make First Controlled Flight

 

The RoboBees project "provides a common motivation for scientists and engineers across the university to build smaller batteries, to design more efficient control systems, and to create stronger, more lightweight materials," says Harvard engineering professor Robert J. Wood. "You might not expect all of these people to work together: vision experts, biologists, materials scientists, electrical engineers. What do they have in common? Well, they all enjoy solving really hard problems." (Credit: Kevin Ma and Pakpong Chirarattananon, Harvard University.)

Strange New Bursts of Gamma Rays Point to a New Way to Destroy a Star

An artist's impression of the stars creating gamma-ray bursts. The background blue star is the progenitor of a standard long duration gamma-ray burst. A so-called Wolf-Rayet star, it has a mass ten or more times the mass of the sun but has a comparable size. The foreground star is the suggested progenitor of an ultra-long gamma-ray burst (GRB). It has a mass of perhaps 20 times the sun but is up to a thousand times larger. In both cases the GRB is produced by a jet punching through the star, but in the case of the ultra-long GRBs the much larger size of the star creates a much longer lived jet. Image copyright Mark A.
