Big Idea: Seeing Crime Before It Happens

This past summer, at an undisclosed location in a northeastern metropolis, the U.S. Department of Homeland Security (DHS) was trying to predict the future. There were no psychics or crystal balls, just a battery of sensors designed to determine human intention through the subtlest of changes in hea... (original story)

Making her move

These days, senior Bethany Tomerlin is just like any other MIT student: She juggles a host of academic and research commitments, plays flute in the MIT Marching Band, and — when she finds a sliver of spare time — indulges what she calls her “pop culture vice” with friends in her dormitory. B... (original story)

A novel way to concentrate sun’s heat

Most technologies for harnessing the sun’s energy capture the light itself, which is turned into electricity using photovoltaic materials. Others use the sun’s thermal energy, usually concentrating the sunlight with mirrors to generate enough heat to boil water and turn a generating turbine. A t... (original story)

Electronics takes on a new spin

Exotic materials called topological insulators, discovered just a few years ago, have yielded some of their secrets to a team of MIT researchers. For the first time, the team showed that light can be used to obtain information about the spin of electrons flowing over the material’s surface, and ha... (original story)
