The Sun is less active magnetically than other stars
Our sun is the source of life on Earth. Its calm glow across billions of years has allowed life to evolve and flourish. This does not mean the sun doesn’t have an active side.

Why The Navy’s UFO Videos Aren’t Showing Aliens
Syfy Wire’s “Bad Astronomy” column is written by astronomer Phil Plait, head science writer of Bill Nye Saves the World. This week he looked at the recently-declassified videos taken by the U.S. Navy’s fighter jets showing unidentified flying objects “moving in weird and unexpected ways.” (“The ‘aura’ around the object in some of the footage could simply be the camera overexposing…

Scientists Create Glowing Plants Using Mushroom Genes
An anonymous reader quotes a report from The Guardian: Emitting an eerie green glow, they look like foliage from a retro computer game, but in fact they are light-emitting plants produced in a laboratory. Researchers say the glowing greenery could not only add an unusual dimension to home decor but also open up a fresh way for scientists to explore the…
Deep Sea Squid Communicate By Glowing Like E-Readers
An anonymous reader quotes a report from NPR: Deep in the Pacific Ocean, six-foot-long Humboldt squid are known for being aggressive, cannibalistic and, according to new research, good communicators. Known as “red devils,” the squid can rapidly change the color of their skin, making different patterns to communicate, something other squid species are known to do. But Humboldt squid live in…

Physicists Disagree Over New Dark Matter Claim
sciencehabit shared this article from Science magazine: For decades, astrophysicists have thought some sort of invisible dark matter must pervade the galaxies and hold them together, although its nature remains a mystery. Now, three physicists claim their observations of empty patches of sky rule out one possible explanation of the strange substance — that it is made out of unusual particles…
