GIFs in space! NASA makes an official channel on Giphy

Via Devin Coldewey at Fubiz: “Nervous System design recently launched this fun Infinite Galaxy Puzzle that tiles continuously in any direction. A brilliant way of resuming the universe expansion theory. Each puzzle is amazingly printed with original NASA satellite pictures.”

Graphene Silly Putty Picks Up Human Pulse

Via Mark Peplow at Nature: “When they wired up a lump of G-putty and held it to a student’s neck, the pulse from his carotid artery was clearly visible in those resistance changes. In fact, the pulse profile was so detailed that they could convert it into an accurate blood-pressure reading. The sensor could also monitor respiration when placed on the student’s chest. And, as a slightly bizarre encore, it recorded the individual steps of a spider weighing just 20 milligrams.”

Brightest ‘supernova’ ever found may actually be a black hole gobbling up a star

Via Loren Grush at The Verge: “In 2015, a group of astronomers spotted one of the brightest and most powerful supernovae ever discovered — a star explosion so luminous that it was poised to reshape our understanding of stellar eruptions. But now, astronomers have taken a closer look at this “supernova” with the Hubble Space Telescope, and they say that it wasn’t an exploding star after all. Instead, they pose a much bleaker scenario: the bright event was the result of a supermassive black hole tearing apart a star that passed way too close.”

Archaeologists Find Traces of Human Organs and Disease in Iron-Age Pottery

Via Kate Horowitz at Mental Floss: “The presence of organ and blood proteins inside the jars suggests that the people of Heuneburg cared lovingly for their dead, interring each organ in its own fine receptacle. The researchers aren’t sure what the virus’s appearance in Heuneburg might mean; we’ve never found hemorrhagic fever on ancient artifacts before.”
