Small but important: The Daniel K. Inoyue Solar Telescope's heat-stop. The heat-stop is a liquid-cooled aperture which reduces the light from the 4m primary mirror to a very narrow beam to protect the secondary mirror and instruments from excessive heat. Failure of the cooling system automatically shuts down the telescope by deploying covers over the primary and secondary mirrors, and closing the dome.

This whole thing is extra-despicable. Ban trophy hunting.

In the beginning, the earliest version of our Milky Way galaxy formed from the merger of two or three smaller galaxies. Now Hans-Walter Rix and colleagues have identified stars from that earliest period - the "poor old heart" of the Milky Way: http://www.mpia.de/news/science/2022-19-ancient-heart
The Chilkat Indian Village of Klukwan is challenging a state permit approving construction of a gold and metals mine that would tunnel under the Saksaia Glacier on 6,100-foot Flower Mountain near the headwaters of the Chilkat River watershed https://alaskabeacon.com/2022/12/18/chilkat-indian-village-says-alaska-mine-poses-risk-to-watershed/
Traditional knowledge that comes from having a balanced spiritual, cultural, and respectful relationship with the land isn't a trick Mother Jones.
Call it what it is: #Indigenous Science.
Reading about Oceanix, a prototype floating community that's planned for Busan. One of the more frustrating things about ideas like this is that it sells the notion as long as you throw enough clean technology at the problem, there doesn't have be any decrease in the standard of living. On our current chaotic climate course, where resources are dwindling and life support systems failing, it doesn't work like that.

Decided to find out what would happen at that other site if I mentioned a #mastodon recently acquired by my museum.
May be on here more often very soon...
#P22 was a reminder that there's no clear distinction between cities and nature. But as walls and highways go up, the landscape becomes fractured. Our job is to reconnect it.
Fun fact: Homes that were in the way of the planned telescopes and buildings were moved to other locations and got new owners, instead of being demolished.
