NREL has produced 1000 patents and 50,000 publications and billions of dollars in economic benefit and the people in charge probably want to kill it
NEW: I heard from a bunch of NREL employees after the announcement of a name change yesterday. They're not thrilled.
"Morale is bad. Funding is tenuous.... I've been through two W administrations, many R congresses, and [the first] Trump admin. This is the worst."

I am once again asking cities to install usable bike parking instead of whatever this is. Could you imagine if cities installed car parking spots that were based on art versus functionality?

Waymo privatized another public street:
Chanel approaching 4th, San Francisco
Possibly queued for a Billie Eilish show at Chase Center ~half mile away.
The light rail train on 4th seen passing in front of this roboherd has more passenger capacity than all of them combined.

As all this disgusting Epstein shit starts surfacing more and more, I hope we don't lose sight of the fact that apparently every major media outlet knew everything and instead spent their time money and energy attacking the trans community.

A Sharon Begley byline, almost 5 years after her death.
Upon hearing the news James Watson had died, a STAT reporter said in our Slack, "I wish I could read what Sharon would have written."
Incredible news: Sharon in fact did pre-write a Watson obit. And it is masterful and excoriating.

You know what is a weird thing I miss about regular TV seasons?
Obligatory seasonal holiday episodes.
Like, no one dropping 8 episodes in July is going to give you an unhinged Halloween ep, a totally inappropriate murder on Christmas ep, and probably some weird Valentine's Day nonsense.
