- nph.onlinelibrary.wiley.com/share/JAIVZX... Excited to share my latest work in @newphyt.bsky.social. Here, we used TurboID proximity labeling with CLAVATA receptors FEA3 and BAM1D in maize meristems to better understand the signaling pathways important for meristem regulation. #PlantScience

- A little over a year ago, I co-directed a short film as part of the Symbiosis Film competition, called "No Two Plants". I was paired with a filmmaker and we had a week to make a short film. I also made the score for the film. I'm sharing it here, please enjoy!
- one of my favorite parts of making the film was being able to show my corn plants around Brooklyn 🌽

- Reposted by Penelope LindsayYes, New College is incredibly inefficient but it also dropped 60(!) spots on the US News & World Report rankings. Not easy! Everytime Chris Rufo is introduced as an impt voice in higher ed, remember that the one time he had a hand in running an institution has been a disaster. Competence matters.

- Reposted by Penelope LindsaySo: In 2017, Congress made this happen: NIH: Proposed 22% cut --> 9% increase NSF: Proposed 11% cut --> 4% increase NOAA: Proposed 16% cut --> 4% increase Obviously, 2025 is not 2017. A lot is diff now. But still: 💰 Congress, not WH, sets budgets. 📞 Public support & calls to Congress matter.
- Reposted by Penelope LindsayHi! Do you want to rip your face off over the constant attacks on science in the US? Here are some actions you can take!

- Reposted by Penelope Lindsay"Women are PIs on 58% of the canceled grants, although they are PIs on only 34% of all active NSF grants. Similarly, Blacks are PIs on 17% of the terminated grants, although they make only 4% of the total pool. Hispanic PIs and those with disabilities were twice as likely to lose a grant."
- Another scoop from Jeff Mervis (@policyhound.bsky.social): NSF's ~1400 grant terminations have disproportionately affected PIs from groups underrepresented in science: women, racial & ethnic minorities, & those with disabilities. 1/3 www.science.org/content/arti...

- Reposted by Penelope LindsayUPDATE: We have data on >1000 terminated #NSF grants at grant-watch.us. Thanks to all who have been contributing data the past few days. We've also added a "Reports" section with some analyses. For NSF, we see that the STEM education directorate has been absolutely pummeled.

My NSF CAREER grant was stolen today; dream project supporting science teachers/students as climate justice action researchers, tackling urban heat. Truly transformative, the culmination of my life’s work, we won’t stop, not in this climate crisis. Gonna fight like hell!

Myself and four scientist colleagues have all been let go from the USDA because we haven't completed our 3 year probationary period - effectively gutting the Cereal Disease Lab.

- Reposted by Penelope LindsayJust got word that our Howard Hughes Medical Institute (HHMI) Inclusive Excellence 3 (IE3) Grant was being canceled. All 100+ institutions. So even private funding is susceptible to this administration’s unraveling of DEI initiatives
- Reposted by Penelope LindsayDarby makes this point but I just want to reinforce it: These words are entirely legitimate to discuss science, accurately and correctly. This attack on "DEI" (🙄) is not only an attempt to resegregate science but also an attack on expertise, itself. Resisting it is a defense of science

- Reposted by Penelope LindsayOkay, this is pretty great. I didn’t realize how much friction it was to look up each phone number until this app had them ready to go, one after another. Plus it tells you how many other people used the app to call about the issue (14,700 on the federal funding freeze alone!)
- Reposted by Penelope LindsayStill frozen out. We’re getting word that people getting Universities to reach out to NSF over this & broader freeze may put pressure on them & help resolve this. If folks could start contacting their uni admin with complaints to forward to NSF (hopefully you know who to contact) it’d help a lot
