BREAKING: A federal judge reversed National Institutes of Health's terminations of hundreds of critical research grants that were canceled because of their alleged connection to disfavored topics, including diversity, equity, inclusion, and gender identity. This is a major win for public health.

Wild Nematodes have been observed forming "living towers" on rotting fruit. These tiny worms are not just making acrobatic towers; they’re hitching rides on insects to explore new territories! 🧪 www.cell.com/current-biol...

Massive"No Kings" rally in downtown #SanDiego today, 60K+ showed up including me y'all - there is hope for a better and brighter future!

Scenes from #NoKingsDay in San Francisco on Saturday: Thousands marched from Dolores Park to Civic Center.

One protein, two opposing roles: This ‘compelling’ study shows how the same signalling molecule can drive either protrusion or retraction in migrating cells depending on its concentration and activation dynamics. buff.ly/pMGXJVM

Princeton's new Omenn-Darling Bioengineering Institute is hiring! New building opening this Fall, & Princeton is an awesome place to live & do amazing research at intersection of engineering & life sciences. **Please spread the word*** bioengineering.princeton.edu/join/open.

California used to be part of Mexico In California it used to be illegal for Chinese people to be outside after dark Laws and borders are social constructs Social constructs are determined by the people, by the values WE share And we can shape history by standing up for our values ✊

My family works in the fields just like this person, putting food on everyone else's table one day to put food on their table for their own children the next day. Hunting people down is disgraceful & disgusting. It has always happened but these days have been the worst.

Immigrants are lazy, don’t work, and are getting freebies from the government. Also, the places they work for shit wages are where we’re picking them all up for deportation.

We feed you. They hunt us.

UPDATE: After video circulated showing ICE agents in San Francisco arresting people outside court, protesters shut the immigration court down for the day. About 200 people amassed outside 100 Montgomery St. The afternoon immigration docket was cancelled. missionlocal.org/2025/06/vide...

“I’m not politicizing science, it was Fauci and liberals that did it!” - Jay Bhattacharya, as he fires a scientific advisor. Before him, scientific freedom and expertise, not politics, took the front seat. #jaylies

We can’t afford cancer centers, HIV vaccines, training grants for people who work on these problems, diabetes or Alzheimer’s or addiction research, but there’s a blank check to the tune of hundreds of millions any time this admin decides to make up a problem to terrorize a city over. Asinine.

I'm literally reviewing NIH grants today (essentially for free, in my spare time). Where along with other experts, I help decide which proposals are the best. Maybe Sen. Britt should learn more about how NIH grant review works?

MAGA HULK SMASH SCIENCE

Reminder: Nobel-prize winning PCR (1983), used in basically all genetic tech today, was only possible because of extremophile bacterium discovered in 1964 in Yellowstone funded by a small ~$80k NSF grant with no obvious application at the time. #science 🧪 www.richmondscientific.com/how-a-discov...

quietly sitting on the fence next to the "defund the police is bad messaging" people, despite police budgets never stopping their growth and militarization as our education and science research budget goes down the drain

ICE nabbed at least 15 people in San Francisco on Wednesday, including a 3-year-old they were at regular check-ins w/ICE when they were taken one family, a 25-year-old mom & two kids, was put in a Texas detention center missionlocal.org/2025/06/ice-...

This little spaceship is a baby sand dollar. It catches particles of food using cilia (tiny hairs). By feeding fluorescent food particles, we're studying which particles it can and cannot catch, which could have implications for the microbes and phytoplankton in the ocean.

During my recent Europe trip, I kept getting asked why we are not in the streets every day protesting. Here is your chance, San Diego. Join us today at noon. I will give brief remarks. See you at UCSD. actionnetwork.org/events/stand...

I cannot stop wheezing

Do you answer if a stranger's first question to you is "where do you work" at a bus stop, in line at the store etc? It's broad daylight & the stranger is friendly & has no red flags (except perhaps that question, depending on your POV). I was a bit surprised this was a convo starter

Trump’s cuts to research programs directly harms scientists from working class backgrounds. Bridges built between the blue collar and ivory tower are collapsing in front of us.

We are also raising money to support undergrads at UCSF this summer! Help me, @neuronush.bsky.social and @quexarce.bsky.social buy ice cream and pizza for our little community of undergraduate researchers! 20% of sales for the rest of the month will go towards our programs!!!

My friend @christineliu.art and fellow IRACDA scholar (oof rip) designs wonderful wearable messages! The enamel pins especially make nice gifts for recent grads 👀 twophotonart.com

A helpful backdoor that I’m absolutely sure a lot of NIH folks have been fighting tooth and nail for over the last few months. Grateful for the advocates But a moment to be petulant…why do I have to reapply for something I was already awarded

We are thrilled to announce the 2025 Leading Edge Fellows! 40 outstanding postdoctoral fellows doing pioneering research in a wide range of biological and biomedical disciplines. Learn more about these exceptional scientists: www.leadingedgesymposium.org/fellows

🤯 Look at this confocal image of a endomycorrhiza fungus inside a 400 million old fossil plant. Check out the new preprint by Christine Strullu-Derrien, @dromius.bsky.social and Ray from @slcuplants.bsky.social www.biorxiv.org/content/10.1... for more pictures and a video. Congratulations 🎉

The National Academy of Sciences is a private, non-profit institution. No one made them host a speaker who said that DEI "degrade our scientific enterprise." Would be nice to see some Academy members speak out on this (or what's the point) www.whitehouse.gov/briefings-st...

nice to finally agree with RFK Jr on something

Racist and sexist roots in the cancellation of NSF grants under Trump: Grants with female PIs canceled 2x more than men Grants with Black PIs canceled 4x over White PIs Grants with Hispanic PIs canceled 2x over White PIs Grants with PIs with disabilities canceled 2x more than without

Of all the awful stuff in this reprehensible bill, the fact that your children stop being considered dependents at SEVEN may be the most horrifying detail.

We found that cells use emergent collective memory—arising from simple chemical reactions—to outperform physical limits of detecting chemical gradients. Curious how? 1/n 8 min talk: www.youtube.com/watch?v=A7XH... bioRxiv: www.biorxiv.org/content/10.1... #biophysics #cellbiology

Ugh Friday morning massacre: NSF 15% IDC www.nsf.gov/policies/doc...

Join us online tomorrow!

PRESSURE WORKS!!!!!! @standupforscience.bsky.social

🚨. I've been mostly off social media for a bit (mental health) but this is very important!!!!! Please comment and circulate to everyone you know for comments!!!

Breast cancer diagnoses rose by over 300% between 1973 and 1992. Was there a breast cancer epidemic?! NO. Mammograms were implemented for screening in 1976. PREVALENCE is a function of being able to correctly diagnose something. This is also about autism.

A government website long used to provide the latest guidelines on managing Covid-19, has now been replaced with a page proclaiming the virus emerged from a lab in Wuhan, China and that Anthony Fauci, the Biden Administration and others worked to cover it up.
