What would happen if you detonated a nuclear weapon deep underground?
U.S. (pseudo)scientific tests, called Project GNOME, experimented with using nuclear weapons to create man made caves. Because, you know… why not?
The results were staggering. The cave that was created by the…
End-Permian extinction happened in 60,000 years—much faster than earlier estimates, MIT study says
The largest mass extinction in the history of animal life occurred some 252 million years ago, wiping out more than 96 percent of marine species and 70 percent of life on land—including the largest insects known to have inhabited the Earth. Multiple theories have aimed to explain the cause of what’s now known as the end-Permian extinction, including an asteroid impact, massive volcanic eruptions, or a cataclysmic cascade of environmental events. But pinpointing the cause of the extinction requires better measurements of how long the extinction period lasted.
Now researchers at MIT have determined that the end-Permian extinction occurred over 60,000 years, give or take 48,000 years—practically instantaneous, from a geologic perspective. The new timescale is based on more precise dating techniques, and indicates that the most severe extinction in history may have happened more than 10 times faster than scientists had previously thought…

When I was a student at Cambridge I remember an anthropology professor holding up a picture of a bone with 28 incisions carved in it. “This is often considered to be man’s first attempt at a calendar,” she explained. She paused as we dutifully wrote this down. “My question to you is this – what man needs to mark 28 days? I would suggest to you that this is woman’s first attempt at a calendar.”
It was a moment that changed my life. In that second I stopped to question almost everything I had been taught about the past. How often had I overlooked women’s contributions? How often had I sped past them as I learned of male achievement and men’s place in the history books? Then I read Rosalind Miles’s book “The Women’s History of the World” (recently republished as “Who Cooked the Last Supper?”) and I knew I needed to look again. History is full of fabulous females who have been systematically ignored, forgotten or simply written out of the records. They’re not all saints, they’re not all geniuses, but they do deserve remembering.

btw forams are tiny wee dudes that float about in the ocean with calcareous shells (like shellfish but less than 1mm in size and without hinges) and help to make up the assortment of things we call plankton. For less of a gross oversimplification check the wiki
