This is the scandal. Trump isn’t targeting dangerous people. He’s targeting peaceful immigrants. Almost exclusively.

Thanks @vineethvengayil.bsky.social for fancying up the lab cart 😍

I mean when I was young I did want to be a writer but I thought the thing I was writing would be more fun to read than grants

I’m in the bar. I’m in the bookstore. I’m in the bar slash bookstore. (I love San Antonio!)

#CancerGenetics people: I am looking for examples of tumor suppressor genes that are inactivated in cancers by regulatory mutations (non-coding) rather than coding mutations. Please share.

people are actually very susceptible to just-so stories about human origins because listening to bullshit helped us survive on the savanna

'Approximately 1 in 30 trials and more than 74 000 trial participants were affected by grant funding disruptions. Affected trials disproportionately studied infectious diseases, prevention, and behavioral interventions, and were based in the Northeastern US or in other countries.'

Kyle Kingsbury is not a journalist. He is not an op-ed writer. He is a computer safety researcher. And he has written one of the most compelling, comprehensive accounts of the ongoing hell in Chicago that you could possibly imagine. In under 1600 words. aphyr.com/posts/397-i-...

This is what every single person with any experience in China has been warning about from the start. Very good WaPo story by Katrina Northrop and Rudy Lu. www.washingtonpost.com/world/2025/1... And good, clear headline!

The Leading Edge Fellows gathered this week to celebrate Zara Weinberg, a beloved member of our community. Our 7th cohort of Leading Edge Fellows (2026) will be named in her honor. The Zara Weinberg Leading Edge Cohort application is now open! Due Feb 2. www.leadingedgesymposium.org/apply/

I study the tumor macro environment (Me trying to submit a grant about basic kidney biology to a cancer foundation)

anyone else going to ABRCMS this month? So excited to see all the work the students present and to talk to attendees about Penn grad programs!

As a PI I am like a dilettante hobbyist of cell culture Once in a while I like to glance at some cells I use the hemocytometer to manually count cells just to show my lab members it’s possible I walk through and give the incubators a nice pat daily

OMG. Arena BioWorks, an ambitious biomedical institute backed by billionaires, abruptly shuts down www.statnews.com/2025/11/04/a... via @statnews.com

Warning. ⚠️ If you are writing an NSF GRFP, new this year, you need official transcripts to apply. Beware. They will not review applications without official transcripts. ‼️

biology is so cool because like every week someone is like "Dr. Smith is coming to campus! She is the world expert in blargyblarg!" And i'm like A) never heard of blargyblarg, B) look it up, it's super important and interesting

Australia has so much clean energy they're literally giving it away. Meanwhile, GOP is in all-out war to stamp out solar www.abc.net.au/news/2025-11...

seeing a lotta grant posts that want to me to solve problems using artificial intelligence consider instead giving me a grant to use CAROLINE INTELLIGENCE slower and dumber but MORE PUNS

tepid take: a lotttttt of job postings for bio-AI researchers, not enough job postings for generating-the-extremely-necessary-data-for-bio-AI researchers

Dr. Weinberg was a MOSAIC scholar and awardee. A brilliant scientist with a strong community service record. Her contribution to making science a safer and better place will never be forgotten. She will be in our hearts forever. 🩷🌷🩷

HAPPY HALLO WNT From the spooky wingless flies 🪰

15 million Americans are going to lose their health care.

excited to read this preprint from rabinowitz lab- how does the body decide which nutrients are burned, and how can this go wrong in T2 diabetes? www.biorxiv.org/content/10.1...

science is a TEAM SPORT there is no ISOLEUCINE in THREONINE GLUTAMATE ALANINE METHIONINE

Names for babies we loved but are not using! For a girl: Sigma Ripa Milli Q For a boy: Taq Amino Eppendorf

I wrote an op-ed on the world-class STEM research ecosystem in the United States, and how this ecosystem is now under attack on multiple fronts by the current administration: newsletter.ofthebrave.org/p/im-an-awar...

I'd need to know more about whether the minister shot in the face with a chemical agent from point-blank range before weighing in on it. Maybe it was good that it happened.

PROPOSAL 2: lil blocks that fit in 50ml tubes and each one weighs 10 or 5 or 1 gram so I can customize my balance tube without dealing with liquid

so excited to visit UCSF today, see friends, and talk about postdoc @vineethvengayil.bsky.social 's work! Thanks so much to Chris Hsiung for the invite!

PROPOSAL: bathroom centrifuges. indispensable for getting the last bit out of a toothpaste tube or shampoo bottle

I ❤️ Philly Halloween

Ok I have a question: why is Hamlet considered the greatest Shakespeare play (or one of the greatest)?

Hi, I'm the ProPublica reporter who's been tracking an unusual stat: U.S. citizens grabbed by immigration agents. I did it because the government isn’t. This is what I found.

what do you mean i have to submit an abstract now for a presentation in april?

Just read: The Husbands by Holly Gramazio. It’s romance slash sci-fi: what if one woman’s attic kept respawning possible husbands in different possible universes? The scenarios get more and more extreme as the book continues leading to mingled fascination and horror for this reader!

I think watching a TikTok of someone doing standard dilutions would be really soothing

Love these beautiful pictures! Congrats to Laith et al!!

my latest investigation for @consumerreports.org is based on months of reporting and 60+ lab tests of leading protein supplements we found that most protein powders and shakes have more lead in one serving than our experts say is safe to have in a day (🧵) www.consumerreports.org/lead/protein...

Congratulations @karalmckinley.bsky.social & lab on their groundbreaking recent preprint establishing + characterizing a chemically inducible model of menstruation in mouse: www.biorxiv.org/content/10.1... My jaw dropped when I heard this presented earlier this year. Incredible.

“A study, published on Wednesday in the New England Journal of Medicine, showed that last season’s 2024–2025 mRNA COVID vaccines reduced people’s risk of emergency department visits by 29%, their risk of hospitalizations by 39% & their risk of death by 64%” Benefits were seen even if 0 risk factors

One of the great advantages of biology is that you can write HELLO WORLD in amino acids since PROTEINS ARE AMAZING
