There were no injuries, although several nearby student residences were evacuated as a precaution.
The cause of the fire is under investigation by members of the Cambridge Fire Department and by MIT safety officials.

By designing chips that can be built using existing fabrication processes, MIT researchers show that computing with light isn’t so far fetched.
