This week astronomers made one of the most important discoveries of the decade. While listening to the sound of two black holes colliding, the LIGO observatory detected gravitational waves, confirming Einstein's last unproven theory. In other science and tech news, MIT is close to cracking the genetic code that could eradicate mosquitos spreading the Zika virus. Researchers at the University of California, Berkeley developed a clever app that uses your smartphone to help predict earthquakes. And an inventor developed a prosthetic arm that kids can customize with LEGO pieces.
