Antimony is important test of whether U.S. can restore supply chains from shutdown caused by Trump tariffs at a time when production dwindled in giant Chinese mine & when China is dominant (60% of world supplies). Antimony is used to harden armaments etc & now scarce.

Do groundwater rights retirement programs work? There is certainly demand for them in Nevada. For KNPR and the Daily Yonder, I talked to irrigators about their experiences with a pilot program in areas where aquifers are being depleted faster than they are replenished. knpr.org/desert-compa...
Well Into the Future
A Nevada program addressed overallocation of groundwater by paying farmers to use less. Is it working?

The White House will not send ANY high-ranking US officials to UN COP global climate conference this year. So California is sending a large delegation, incl Gov Newsom, to build on state's climate cred & as a US proxy. (I’m a bit over COPs but glad someone’s going.)

"To rebuild our scientific enterprise, we need support of the American people...Policies to forbid ghostwriting [research reports by corporations published under other authors' names] & strong[er] sanctions" for violators are needed--Naomi Oreskes, today's Science

www.science.org/doi/10.1126/...
Cleaning the scientific house: Rebuilding trust in science requires confronting the harms of ghostwriting
American science is under attack. Recent cuts to funding and staffing of federal agencies, layoffs of scientists, and rescission of billions of dollars in grants are unprecedented in US history and threaten the stability of the scientific infrastructure that, since World War II, has made the US the world’s global scientific leader. So this might not seem the right time to raise questions about scientific integrity. When someone is burning down your house, it is probably not the right time to worry about cleaning it. But if someone is trying to dismantle your house, then it is a good time to shore up its foundations.
