Dallas' hard-earned diversity of leadership may help city heal after police shootings - The Dallas Morning News An acknowledgement of a dark and painful past, but a positive and hopeful article about the future. Dallas is a diverse city and a great city. My greatest hope is that the visions expressed by city leaders in this article come to pass, and that the rest of the country will follow.

Mysterious underground rings built by Neandertals

New study reveals deep cave exploration, as well as the oldest evidence of Neandertal building

Deep within a French cave where no light penetrates are two curious structures: large rings of stalagmites, some broken and arranged like the rails of old-fashioned wooden fences. When discovered in the early 1990s, scientists didn’t know what to make of the formations, which appeared to be fire-scorched in places. Now, they may have an answer: The rings were built by Neandertals, who learned to explore caves extensively and engaged in complex building behaviors like arranging stones more than 175,000 years ago, much earlier than thought.

The ancient structures—more than 330 meters inside the current entrance to the cave—include a scattering of small, deliberately arranged heaps of stone along with two large rings, one about 2.2 meters across and the other nearly three times that size. The rings and piles are made of about 400 stalagmites of similar size, weighing a total of 2.2 tons.

Most of the forearm-sized fragments are roughly cylindrical and were intentionally broken to the proper length, says Sophie Verheyden, a geologist at the Royal Belgian Institute of Natural Sciences in Brussels. That much is clear, she says, because the pieces are missing both their tips and their bases. “I’m a caver, and those structures are something like I’ve never seen before”…

Fascinating Scientific American article.

So many consequences for all of us. It will be interesting to see how all of this plays out, for better or for worse.
