An unconventional Rubisco small subunit underpins the CO2-concentrating organelle in land plants In many algae, photosynthesis is boosted by biophysical CO2-concentrating mechanisms, which pack the CO2-fixing enzyme Rubisco into liquid-like organelles called pyrenoids. Engineering C3 crops with a...

Our work on #hornwort #pyrenoids is finally out in @science.org! 🎉 We uncovered how hornworts pack their Rubisco into pyrenoids and successfully recreated them in Arabidopsis. A key step toward engineering more efficient photosynthesis in crops @btiscience.bsky.social www.science.org/doi/10.1126/...

A billion dollars a day to commit wholesale slaughter, not a single fucking penny for health care. America, 2026.

So... A friend was supposed to give a PURELY SCIENTIFIC talk at NIH within the next couple of weeks and it was cancelled because of a "new process" where all speakers/talks have to be CLEARED BY A POLITICAL APPOINTEE.

Lol no. Just unpleasant strings of consonants.

My mom learned English as an adult and we would tease her when she said "fishes." She was so delighted when I one day told her that sometimes her usage of fishes was actually correct!

I think our season is already over! 😭

Enabling Fieldwork for All (EFFA) Framework: Supporting physical, social, financial, and psychological safety in the field Comprehensive review of fieldwork safety literature across disciplines yields synthesized recommendations.

Excited to share a new paper written by a AAAS Policy Fellow I mentor, Dr. Lisa Walsh.

“This review synthesizes literature on fieldwork safety across scientific disciplines, highlighting four facets of safety for leaders and researchers to address: physical, social, financial, and psychological.”

The president of the uni, opening an email with hopes that we are staying warm while watching UConn athletics and "supporting..our coaches," all while staff face looming cuts, is a wild choice.

I simultaneously want to be back home, but also not, because *waves vaguely at everything*

after absolutely eviscerating Kristi Noem and calling for her resignation, Tillis is applauded. He thens threatens to hold up nominees if she doesn't stop stonewalling him. My God.

Square graphic featuring a close-up pink and purple flower background. The Botanical Society of America logo appears at the top. Centered text reads “BSA Impact Award” and “Deadline May 1, 2026.” A description states that the award honors a BSA member, group, or institution for impactful work that builds a more inclusive and engaged community in botanical research and education, including efforts that influence practices and policies or expand access to knowledge and resources through research, teaching, or outreach. A link to www.botany.org/home/awards.html appears at the bottom.

Nominations are open for the BSA Impact Award!

This award honors a BSA member, group, or institution whose work expands access, strengthens community, and improves practices in botanical research and education.

I let out an audible gasp.

What in the absolute fuck.

There's a dark, dark, history of this. Of forced sterilization.

I am so, so sick.

🚨Two fully funded PhD opportunities in Australia!

HOW DARE YOU

$300 Million in jet planes lost to a fuckup.

That’s 83 five year NIH R01 grants burned in minutes due to error, aka poor execution of this unnecessary war which serves only to make the world more dangerous.

I'd like to remind everyone that CAM has evolved as many if not more times than C4. There are entire biomes where CAM is dominant. If you like tequila, or pineapple, or your pretty orchid you got at the grocery store, you can thank CAM.

Thank you for coming to my TEDtalk. Or CAMtalk as it were.

How do you write a thing about photosynthetic pathways and not mention CAM. How.

They're soooo goofy. Boulders is where we were today!

I am confident they are not CAM

White House stalls release of approved US science budgets The US Congress rejected sweeping cuts to science agencies. But the NIH, the NSF and NASA have had their spending slowed.

Congress rejected massive cuts to US science budgets for 2026, but much of the money still isn’t flowing to researchers.

The culprit? The White House Office of Management and Budget (OMB) is quietly slow-walking the release of funds. 🧵👇

They went to war with Iran (which nobody in America was asking for) so they could conjure an excuse to allow ICE to keep murdering Americans and teargassing schools here at home with impunity (which nobody in America was asking for).

In a time of extreme division, I am glad we can be united by one trait: the inability to keep oneself from playing videos on your phone full volume in public spaces.

Worldwide phenomenon.

Wtf. Why not. WHY NOT
