Ok geology pals, I need some help. In your opinion what are the “best” disaster movies? Specifically -
1) The 'best' or most scientifically interesting depiction of a disaster
2) The funniest or most ridiculous disaster movie
3) Your favorite 'guilty pleasure' disaster movie

Also, it is fantastic that the EPA makes this information so accessible. It helps with decisions for everyone living in the area and is so important for people who are sensitive to poor air quality. We should continue to fund all of this!

Advice needed: A former student now in industry is asking about pros/cons of doing an industry-sponsored PhD, given the current climate and not getting in anywhere this cycle. I remember there was chatter about this a couple years ago but it's a good time to revive this chat. Please RT.

If you're a researcher with an NSF grant that has been terminated or with a proposal now stuck in limbo, I'd like to hear from you.
My signal is kvasquez.12. Anonymity is always an option.

NSF announced that it has begun terminating awards. It's unclear how many affected. Sources say it could be over 200
It's also re-reviewing proposals that had already been approved for funding
Here's a breakdown of what's happened this week: cen.acs.org/policy/resea...

So sad to hear about the passing of Stan Sander. He was an incredible scientist, but also a really kind and nice person.
@NASA and @caltech.edu kineticist extraordinaire Stan Sander died Saturday night surrounded by his family. Stan was a kind mentor, inventive scientist and engineer. He will be sorely missed by me and many colleagues around the world.
