You probably already know this, but today was the first full missed pay check for most of your friends, colleagues, POs and SROs at the NIH. Stay strong out there folks. If you need help, ask for it. As always, try to be kind.

Excited to share this new work from the lab, in collaboration with @jtuscher.bsky.social & Rob Sorge! Here, we used single cell transcriptional profiling to define molecular adaptations induced by chronic pain and opioid experience, which often occur in conjunction. www.biorxiv.org/content/10.1...

I beg my science colleagues to speak with the media about what's happening now. When I was given the opportunity, I spoke with Nature about HHMI massive cut. I am an immigrant on a working visa, and I am not a professor. Anyone can talk. Silence in the face of injustice is injustice in action.
Nature news, Feb 7, 2025. Have Trump’s anti-DEI orders hit private funders? HHMI halts inclusive science programme
The Howard Hughes Medical Institute, a huge funder of biomedical research, has cut a $60-million initiative to boost diversity in science education.
