Now published @NatureCellBio! Kinase KEY1 controls pyrenoid condensate size throughout the cell cycle by disrupting phase separation interactions nature.com/articles/s4155…

Congrats, @Shan_He_lab and Linnea Lemma!

Congrats to Tori, Micah, Aastha, and @LianyongW! Grateful to @hhmi_science, @NIH, @NSF, @gatesfoundation, and @FCDOGovUK for supporting the work.

We genetically disconnected starch from the matrix in the algal pyrenoid! A saga1;saga2 double mutant lacks a pyrenoid starch sheath! Our model: SAGA1 & SAGA2 locally initiate starch on the pyrenoid surface by enriching starch precursors. 🌞🦠🔬🔌👀 biorxiv.org/content/10.6..…

Nice examples of key discoveries that created industries and were only possible by funding basic exploratory research. nature.com/articles/d4158…

Congrats to the team including @Shanhe_PU, @lsquared64, @almcalvo, @lianyongw, @Ashwani_Rai1, @brangwynnelab, and Ned Wingreen! Grateful to @HHMINEWS , @NSF, @DOEScience, @NIH, and @HFSP for supporting this interdisciplinary project.

How did the US become the global leader in science and technology? Answer: decades of federal investment in basic research, including through the National Science Foundation and Department of Energy. aps.org/apsnews/2025/1…

Algal pyrenoids—condensates that mediate ~1/3 of Earth’s CO2 fixation—change size and number as cells divide. Our data suggest a simple control mechanism: a kinase that continuously ejects material from the condensate! ☀️🌍🔬💧 #Biophysics #Photosynthesis biorxiv.org/content/10.110…

Exciting new study from @aburlacot and @Yeh_Lab ! A genome-wide CRISPR screen in diatoms!

Lev’s latest comic strip! For a school project on the properties of matter!

I was deeply saddened today to learn of the passing of Steve Long @LongLab. He was a pioneer and an inspiration to so many of us. Find his obituary here: renner-wikoffchapel.com/obituary/Steph…

Congratulations to the 2025 Gilliam Fellows @HHMINEWS! hhmi.org/programs/gilli…

@OlzmannLab Congratulations, @OlzmannLab!

I am honored to be named a 2025 ASCB Fellow! It is a privilege to be part of the ASCB community. ASCB was the first conference I attended as a grad student, and it has always been a welcoming, supportive home. Thank you for this kind recognition! ☺️ ascb.org/society-news/f…

@LevsArt Lev has survived 45 days in “Hardcore Minecraft”! He won’t let me play with him anymore because I’m “such a noob”.

Pretty sure nobody in the US wants children to starve to death. We could easily make our military aid to Israel conditional on humanitarian treatment of Gazans. Why are we not doing this? cnn.com/2025/07/23/wor…

Yep, this is where we’re going! Can You Believe Your Own Eyes? Not With A.I. | Op-Docs youtu.be/Sf3wEg9tsCY?si…

@GavinNewsom Yes, we must protest peacefully.

America, 2025: Caregivers running from ICE agents and ICE agents putting kids into the back of a van at a park. Tomorrow, as protests happen across the nation don’t give Trump what he wants. You can be angry—I am. But be stubbornly peaceful. That’s how real change happens.

@GavinNewsom Yes, let’s protest peacefully.

Excellent explanation for anyone who thinks cutting grants to punish universities is a good idea. readtangle.com/otherposts/wha…
