TechCrunch reporter Darrell Etherington writes that MIT researchers have developed a framework for determining the best course of action to take to deflect an incoming asteroid. The researchers developed a “decision map” that takes into account “the mass and relative momentum of an approaching asteroid, as well as the expected time we have before it enters into a so-called ‘keyhole.’”

Verge reporter Thomas Ricker writes that MIT researchers have developed a new RFID sensor that could be used to detect moisture in diapers and send an alert to caregivers. “The sensor can be manufactured for less than 2 cents, making it suitable for disposable diapers without adding bulk,” Ricker explains.

Atlantic reporter Conor Friedersdorf highlights a new study by MIT researchers that shows handwashing at airports could help reduce the spread of disease.

Graduate student Clara Park speaks with Ira Flatow of Science Friday about her work developing a bionic heart that could be used to test cardiac devices. Park explains that she and her colleagues fused a real heart “with robotic muscles to mimic the realistic motions and anatomy of the heart.”

MIT researchers have developed a new smart diaper that can send caregivers a message when it detects moisture, reports Caroline Enos for The Boston Globe. “A small moisture sensor in the diaper contains a radio frequency identification tag, which transmits a radio signal to a nearby receiver when the diaper becomes wet,” Enos writes.
