8:30 PM | Can Robots Help Fight Ebola?
Helping Hand Takao Someya Group/University of Tokyo Engineers make disaster-response robots precisely because robots are able to work in situations that are too dangerous for humans. Now the humans have got a new idea: Perhaps robots could carry off waste from Ebola patients, or bury the bodies of people who have died from Ebola in West Africa. Roboticizing such tasks would keep people from having to touch bodies when they're most infectious. Working with the White […]

6:01 PM | A Look At The Sun Beneath The Corona
IRIS View of the Sun, December 2013 NASA Human eyes can't (or at least shouldn't) look directly at the sun, but NASA's IRIS can. The Interface Region Imaging Spectrograph mission is the latest to fly into space to observe the solar atmosphere. Now, a little more than a year after it launched, the satellite has sent back a complex picture of a special region of the sun, just below its corona. IRIS observes the sun's ultraviolet radiation, which can't be seen by […]
