New research suggests that a large space rock exploded over Antarctica thousands of years ago, leaving a scattering of tiny meteoric particles and a layer of extraterrestrial dust.
New research suggests that a large space rock exploded over Antarctica thousands of years ago, leaving a scattering of tiny meteoric particles and a layer of extraterrestrial dust. Evidence of this so-called "alien dust" has been found in Antarctic ice cores, and scientific findings about its existence were presented at a major science conference in Texas. It has been suggested that such an explosion is comparable to the Tungusta space blast, which flattened a large area of the Siberian forest in 1908. An air burst means that the meteor or space rock doesn’t reach the Earth’s surface but instead explodes in the atmosphere. "The research is based on a study of extraterrestrial debris found in granite from Miller Butte, in the Transantarctic Mountains, and a layer of cosmic dust represented in two Antarctic ice cores. The debris from the mountains includes micrometeorites and tiny particles called spherules. The study's authors think these spherules could be material eroded from a stony meteorite as it was heated up on its way through our atmosphere."

Moans, groans, and gripes release stress hormones in the brain.
Could you give up complaining for a whole month? That's the crux of this interesting piece by Jessica Hullinger over at Fast Company. Hullinger explores the reasons why humans are so predisposed to griping and why, despite these predispositions, we should all try to complain less. As for no complaining for a month, that was the goal for people enrolled in the Complaint Restraint project.
Participants sought to go the entirety of February without so much as a moan, groan, or bellyache.
- Facebook and Google began as companies with supposedly noble purposes.
- Creating a more connected world and indexing the world's information: what could be better than that?
- But pressure to return value to shareholders came at the expense of their own users.
