So important to keep our voices heard!! Extra special getting to speak after @nancyhong.bsky.social, and loved seeing such a strong showing from my lab at @standupforscience.bsky.social at UCSD!

Here is our newest paper recently published in Plant Communications on "Root hair growth under the control of auxin under low temperature low nutrient environment". Comments and suggestions are more than welcome! Here the pdf www.cell.com/plant-commun... Leaded by Victoria Berdion Gabarain et al.

A word cloud made from flagged terms in terminated NIH grant proposals. The most prominent words in large font include “trans,” “diverse,” “diversity,” “minority,” “sex,” “expression,” “mental health,” “gender,” and “women.” Other visible terms include “LGBTQ,” “racial,” “underrepresented,” “disability,” “barriers,” “black,” “equity,” “health equity,” “vaccine,” “bias,” and “intersectionality.” The word cloud highlights terms related to identity, inclusion, and marginalized communities.

HAPPY PRIDE 🏳️‍🌈

Under Trump, research using terms like “Trans,” “LGBTQ,” & “Gender identity” is being defunded. These terms reflect real people who deserve science that includes them.

Stand with us to protect LGBTQ+ science from political erasure.

On this #BiodiversityDay, let’s remember:

Fundamental shifts in how people view and interact with the natural world are urgently needed to halt and reverse #biodiversity loss. 🌍

Let's protect our planet's biodiversity—our true force. 🌍💫🧪

#MayThe4thBeWithYou

Planting the Seeds of Change: Communicating Science with Purpose. An online student-led symposium series, featuring Dr. Molly Edwards. We’ll discuss best practices for short-form video production, explore different formats and approaches, and workshop your own ideas for videos. You’ll come away with actionable steps for producing your own video that stands up for science, and we plan to stay in touch after the workshop ends to help each other amplify our videos when they come out. May 13th, 8-9am PDT / 11am - noon EDT. Open to all, come be a part of it!

Join us for an exciting Student Symposium workshop featuring Molly Edwards, PhD @science-irl.bsky.social. It's an interactive workshop on science communication, focused on short-form video production. May 13th 11am EDT.

Proud to present the first data paper from the lab, published today in @pnas.org.

We describe a new mechanism for CLE peptides as local symbiosis-amplifying signals, promoting plant interactions with beneficial arbuscular mycorrhizal fungi.

Congratulations @sagarbashyal.bsky.social et al.!

My entire team wrote an opinion paper about Common misconceptions of speciation research. Each section is written by 1-2 team members. The bulk of the writing happened during two writing retreats. It was a lot of fun and I am very happy with the result. academic.oup.com/evolinnean/a...

This image shows a small cactus with fine spines growing in rocky, dry soil. The cactus has two yellow flowers in full bloom, positioned at the top of the plant. Each flower has numerous long, pointed tepals, with a golden centre full of thin, white stamens.

The cactus flower season at the museum is coming 🌵
