Hot Jupiter ‘Companions’ could shed light on planet formation.

The discovery of two exoplanet "companions" provides insight into the hot Jupiter solar system, discovered from data collected by the K2 mission. Out of the some 300 hot Jupiters that have been spotted over the past two decades, these new objects are the first close-in planets to be discovered. Discovery of two close-in planet companions sheds new light on planet formation. For the past 20 years, astronomers peered into the night sky, puzzled about a type of planet called hot Jupiters. As they a...

A mirror that monitors vital signs

Wish you could check your vital stats while brushing your teeth? Thanks to the new innovation by MIT PhD student Ming-Zher Poh, reading your pulse and other vital stats may someday be as easy as standing in your bathroom. Working with public-domain software, Poh developed a way to measure the pulse by analyzing subjects sitting in front of a two-way mirror. The MIT Media Lab Medical Mirror is equipped with a computer monitor along with a built-in camera that tracks changes in brightness pr...
