'Stealth' material hides hot objects from infrared eyes

27-Jun-2018

Infrared cameras are the heat-sensing eyes that help drones find their targets even in the dead of night or through heavy fog. Hiding from such detectors could become much easier, thanks to a new cloaking material that renders objects -- and people -- practically invisible. "What we have shown is ...

Long-Sought Workaround to Helium Shortage?

Neutron Detection Method

12-Jun-2018

Doctors use X-rays to see inside people, and scientists use neutrons to peer inside advanced materials and devices such as fuel cells to better understand and improve them. But a critical shortage of a rare form of helium used for detecting neutrons—which are difficult to spot directly—threatens ...
