This tiny grain-of-rice sensor gives robots a new sense and changes what delicate tools can detect

NASA's Psyche spacecraft will get a boost from Mars on Friday, May 15, passing just 2,800 miles (4,500 kilometers) from the planet's surface at some 12,333 mph (19,848 kph).

This week, researchers reported that the human brain is capable of sophisticated language processing while in an unconscious state during general anesthesia. An informatics and computing professor found that the Climate TRACE consortium has underestimated vehicle carbon emissions in cities by a staggering 70%. And archaeologists excavated and photoscanned a prehistoric man-made island located in a Scottish loch.

If you're dealing with a relationship marked by conflict, criticism or manipulation—be it with a parent, co-parent or colleague—chances are you've come across the "gray rock" method on social media or advice blogs.

A single-atom platinum catalyst lights ammonia at 200 °C and keeps it burning steadily at 1,100 °C with low NOx, generating high-grade, carbon-free heat for steel, cement and chemicals.
