All over the internets and every kind of news media: a large meteor streaking across the early morning sky of Western Siberia.  The New York Times has many video clips, and an explanation for the ubiquitous dashcams in Russian vehicles that took them:

Psychopaths are abundant on Russian roads. You best not cut anyone off or undertake some other type of maneuver that might inconvenience the 200-pound, six-foot-five brawling children you see on YouTube hopping out of their SUVs with their dukes up. They will go ballistic in a snap, drive in front of you, brake suddenly, block you off, jump out and run towards your vehicle. Next thing you start getting punches in your face because your didn’t roll up your windows, or getting pulled out of the car and beaten because you didn’t lock the doors.

These fights happen all the time and you can’t really press charges. Point to your broken nose or smashed windows all you want. The Russian courts don’t like verbal claims. They do, however, like to send people to jail for battery and property destruction if there’s definite video proof.

And here's an image of the meteor's vapour trail, taken from orbit.

Sort of related to intrusions from outer space, the uncanny valley of incredibly life-like David Bowie dolls.

Throughout her career, the famous biologist Lynn Margulis (1938-2011) argued that the world of microorganisms has a much larger impact on the entire biosphere—the world of all living things—than scientists typically recognize. Now a team of scientists from universities around the world has collected and compiled the results of hundreds of studies, most from within the past decade, on animal-bacterial interactions, and have shown that Margulis was right. The combined results suggest that the evidence supporting Margulis' view has reached a tipping point, demanding that scientists reexamine some of the fundamental features of life through the lens of the complex, codependent relationships among bacteria and other very different life forms.
