Why does the naked mole rat have the longest lifespan of any rodent, nearly 40 years?
A 30-year long mystery unraveled @ScienceMagazine today!
Its cGAS enzyme in cells has 4 missense mutations that upends its function, promoting DNA repair and suppressing inflammation

This grant will support a senior graduate student as they complete their thesis research, despite funding that was abruptly canceled.

Thank you @acs.org for putting money and effort into supporting young scientists! /end

In this time where many institutions are attacking science and marginalized scientists or standing by, it is important to call out those that are providing support.

In that spirit, thank you @acs.org for supporting the Kritzer Lab with a Graduate Success Grant. /1

Here’s the thing I wish everyone could hold in their minds about writers—we love em dashes. We use em dashes. We are humans and not AI. We will not be deleting our em dashes just because AI uses them too. We were here first. You can pry my em dashes from my cold dead hands. F*ck AI.

A small primer on the #NobelPrize awarded to Mary E. Brunkow, Fred Ramsdell and Shimon Sakaguchi today. This prize was for combining two separate fields of immunology research - genetic research on IPEX and immunology research of regulatory T cells (#Tregs), with enormous impact on biology/medicine

This Anthropic settlement case…fellow authors, are any of you feeling rage? I have 12 books listed and money (I don’t CARE how many thousands, even millions) is NOT adequate compensation. What was stolen & used without my permission is priceless! Where is the option to scrub my work from AI?!

1. Take this seriously. Here is how you do it. Take a screenshot of the #HatchAct violation, whether it's on LinkedIn or other social media or on the actual US Government website. When you file your complaint, provide your personal contact information. If you're a furloughed fed, you're off-duty.

OSC tells us how to file a #HatchAct complaint. Nearly all federal sites are in violation. Do not accept this as normal. #FEDSTRONG

#NobelPrize week starts tomorrow & the #chemnobel is Wednesday… used to be so much Nobel chat on Tw*tter, but that is not replicated here, alas. Anyway, for the record, I think MOFs will win at some point (maybe this year maybe not). Balasubramanian & Klenerman a good bet for next-gen sequencing too

Puffins return to Maine after half a century of absence. Eastern Egg Rock now hosts the only puffin colony in the United States, restored through decades of painstaking work after the birds were hunted out a century ago. buff.ly/RB0Ibz0

How researchers restored a thriving habitat for Atlantic puffins in Maine
Atlantic puffins face an increasingly precarious foothold due in part to a loss of habitat and to troubles tied to warming ocean waters and climate change. But an effort off the coast of Maine…

Six weeks ago, I picked up a year-old tawny owl with a broken leg off the main road near our home and dropped him off at our nearest vet.

After a few days, I received one of the most bizarre phone calls I’ve ever had, asking “So when are you coming to pick up your owl?” 🧵

Whoa 😮 excellent technique with some really cool results on what happens to cell-penetrating peptides when they enter the endocytic pathway. Read the thread 👇 then read the paper (open access!).

Jeanne Marrazzo, director of NIAID, claimed that the Trump Administration’s actions
endangered research subjects, defied court orders & undermined vaccine research.

Earlier, Kennedy fired Susan Monarez of the CDC.

Resisting unethical policies costs you.

Super exciting work, and a bonus to see a major university research department promote an exciting @biorxivpreprint.bsky.social preprint rather than wait 9-12 months for the final version 👏🏽

What can HaloTag do for you?

Triggered fluorogenic labelling?
Molecular recording?
Photo-Chemically Induced Dimerisation?

Philipp Mauker's CHalo motif lets reagents do all three, and more.

1. Dr. Jane Goodall 1934 - 2025

In 1962, a very young woman named Jane Goodall stepped into the African forest.

What she would discover shattered our understanding of the place of human beings in the world.

She revealed that chimpanzees use tools, form bonds, and experience emotions.

Molecular Recording with HaloTag?
H2O2, GSH, Trx, LAP?

→ multiplexable reagents record diverse enzyme activities ratiometrically, without signal loss
