Some awesome, fundamental work here: Lucy Shapiro, on bacterial cell differentiation, Dirk Görlich and Steve McKnight on IDRs & protein gels in nuclear pores and biomolecular condensates, & Michael Welsh, Jesús González & Paul Negulescu, (overdue) for bench to bedside work on cystic fibrosis 🧪 1/2

Brain tumours in mice grow more slowly when starved of key amino acid

Read former NIAID Director, Dr. Jeanne Marrazzo’s, Whistleblower complaint. It mirrors the concerns we expressed in the Bethesda Declaration and confirms the administration knew full well the harmful consequences of their actions.

This job is such that I did not get a single thing done on my main to do list this week, and yet I worked almost nonstop.

Hello world! Today’s officially the first day of the lab! It’s an empty space currently only filled with ideas (that I don’t have card access to yet 😂) but I’m excited for the science that will happen here! -JCG

Underneath it’s written “as an assistant professor 9/2/2025” although that doesn’t come out as clear in the photo.

In the past couple weeks, people have really stepped up to ensure all ABRCMS students have a great experience, so THANK YOU!

There are still a few disciplines that could use some help: where are my Cell Bio, Cancer Bio, and Immunology folks at?!?

History shows us the opposite: Undermining and censoring scientists and experts is a central feature of authoritarianism.

NEW: Don't ask too many questions, but...

NIH may not re-terminate the 900ish grants at issue in the main NIH lawsuits after all.

To the PIs of reinstated grants, SPEND NOW!

In case you were wondering how hiring a $10 million football coach when the Legislature is implementing $70 million in UNC-CH budget cuts starting in fiscal year 2025, with ~$29.5 million in cuts occurring this year, here the answer: for "safety" most of us are banned from much of campus Monday

If you are a researcher whose lab uses FlyBase, consider a tax-deductible personal contribution. A lot of $100 contributions would help bridge the gap until we can set up a user fee system, and even $10 donations send the folks there the message we're behind them. Please share
