🌱 aspbofficial.bsky.social presented @kcox-bioguy.bsky.social Kevin Cox, PhD, the Eric E. Conn Young Investigator Award in recognition of his contributions to plant pathology and spatial biology research & commitment to meaningful outreach and service. Congrats Kevin! loom.ly/jIIgq2o

This is fantastic! I'm very lucky to work with excellent scientists like Dr. Kevin Cox @kcox-bioguy.bsky.social. Here's our foray into XRM imaging of the duckweed species Wolffia australiana. Thanks KC for this awesome collaboration!

Highlight of my evening, feeding blackberries to a turtle in the yard😍🐢

I'm thrilled to co-chair this session at ASPB on X-ray imaging in Plant Biology, lab-based and synchrotron.

Along with “fund science save lives” we also need the slogan “fund science save the economy”. I’m afraid many voters here aren’t interested in saving lives.

Aw! Happy belated birthday!!

Dact1 induces Dishevelled oligomerization to facilitate binding partner switch and signalosome formation during convergent extension - Nature Communications The action of non-canonical Wnt signaling during tissue morphogenesis remains unclear. Here, the authors find that Dact1 promotes oligomerization of Dvl to couple its binding partner switch from Vangl...

🧪 My PhD research is now published in @naturecomms.bsky.social! If you're interested in non-canonical Wnt signaling during convergent extension, check it out! We developed a novel model suggesting that Dvl2 oligomerization modulates a binding switch from Vangl2 to Fz7.

Crowd of people standing outside the Union Station Hotel in St. Louis, Missouri in a Stand Up for Science Walkout.

Thank you to the Maize Genetics Meeting - yesterday we had an advocacy session, followed by Stand Up for Science walk-out. We are missing our USDA colleagues, who were not allowed to attend the meeting!

ExPOSE: a comprehensive toolkit to perform expansion microscopy in plant protoplast systems This method provides a robust approach for performing expansion microscopy in plant protoplasts for imaging single-cell and subcellular compartments at greatly enhanced resolution.

Some of my postdoc work has been "exposed" today in @theplantjournal.bsky.social! 😁🎉🔬 We developed ExPOSE - a method to perform expansion microscopy in plant protoplast systems. Here's a quick🧵of the details: @meter76.bsky.social @lily-oconnor.bsky.social

2025 Black History Month: Black Plant Scientists Spotlight | Plantae An initiative originated by Kevin Cox Jr., PhD, Plantae carries on Kevin’s tremendous effort of bringing visibility to several exceptional scientists and their work across the science community.

Every February, @kcox-bioguy.bsky.social puts together a list honoring one Black plant scientist for each day of #BlackHistoryMonth. Read his full article via @plantaeofficial.bsky.social and meet all 28 scientists: loom.ly/AMg1m_4

I'm extremely grateful and excited to work with Tessa and Kirk on improving plant cryo-preparation techniques to achieve even better electron microscopy images and reveal new insights about the inner workings of plant cells. 🌱🔬

This study is generously funded by the NSF PGRP 😊🧪

Equipped with state-of-the-art technology, Tessa Burch-Smith, PhD, and Kirk Czymmek, PhD, are setting out to develop imaging procedures that would allow scientists to view the intricate world of plant cells with more precision than ever before. Read more: loom.ly/V-3XXZQ

🎉 Advanced Bioimaging Laboratory Manager Anastasiya (Nastia) Klebanovych, PhD, received two awards in @bioimagingna.bsky.social’s 2024 Image Contest! Her quinoa pollen grain image won second place & her hellebore pollen grain earned an honorable mention. Congrats, Nastia!

FOR IMMEDIATE RELEASE Stand Up For Science 2025 Announces National Day of Action: March 7, 2025 WHAT: A rally to defend science as a public good and central pillar of social progress. WHY: Science is for everyone–and benefits everyone. When the federal government supports scientific research through taxpayer funding, it fuels innovation, creates jobs, and sustains the world we live in. From purified water to the polio vaccine to the cell phone you might be reading this on, science has significantly impacted our lives in countless ways. We’re mobilizing to keep science free from interference and censorship by government officials. We’re also mobilizing because attacks on diversity, equity, inclusion, and access are attacks on science, and vice versa. Science is at its best when it includes everyone and when it stands to improve people’s lives. It’s time–as ever–to stand up for science, for everyone who does it, and for everyone who benefits from it. WHO: Everyone! If your life is better because of science, this rally is for you. WHERE: Washington, DC & state capitals nationwide WHEN: March 7, 2025 Forthcoming details about local rallies: www.standupforscience2025.org Press contact: standupforscience2025@gmail.com

Sent a DM the other day like "Yeah, I'll help!" and now I'm co-authoring press releases for an honest-to-god nationwide science protest, like WHAT

How Ironic that on the International Day of Women and Girls in Science, Woman's portraits have been taken down at NIH and Women is a forbidden word that if found in your NSF grant could get it revoked. #womeninstem

The Danforth Center celebrates #InternationalDayOfWomenAndGirlsInScience, which honors women’s brilliant contributions to science and recognizes the ongoing need to address the gender gap in STEM fields.

I'm trying to stay positive and push imaging boundaries. The latest fascinating project is XRM imaging of Marchantia colonized by a mycorrhizal fungus. I'm sure there are false positives in this quick manual segmentation, but certainly some cool AMF structures as well. A satisfying first scan.

White House budget proposal could shatter the National Science Foundation “This kind of cut would kill American science and boost China.”…

A layoff of 25-50% NSF staff members AND a possible 66% budget cut? This is terrifying.
