MIT Scientists Can Look at Your Insides From a Distance

A series of lasers acts like an ultrasound without requiring physical contact.

Scientists have developed a system of lasers that can probe inside the human body, much like an ultrasound, but from a distance.

The system can accurately image what’s going on inside a person’s body up to a depth of about six centimeters, according to an MIT press release. While that may not seem like much, it’s still an important first step in removing physical contact from ultrasound scans, as that can sometimes introduce variability in a doctor’s readings.

Astronomer: Use Lasers as Earth’s “Porch Light” to Attract Aliens

By MIT News – Re-Blogged From WUWT

Via MIT News and the “Astronomers with frickin’ laser beams on their heads” department comes this odd idea.

If extraterrestrial intelligence exists somewhere in our galaxy, a new MIT study proposes that laser technology on Earth could, in principle, be fashioned into something of a planetary porch light — a beacon strong enough to attract attention from as far as 20,000 light years away.
