Good morning! 🪶

The celebration of Juneteenth started in Galveston, but its impact is felt far beyond Texas. Generations of Americans refused to accept that freedom belongs just to some. They understood that freedom is something to cherish, and that each generation must continue the fight for justice and equality.

Fruit shape tells a story of angiosperm evolution.

Trying to find a time for 6 scientists (across multiple time zones) to hop on a call…over the summer:

Fun fact: I did the start of my postdoc in her old lab space. Funner fact: I used to talk to her ghost.

Very happy to see that SUBER GENE1 (SBG1; At1g52565) is now annotated in TAIR and Aramemnon! We identified this gene through a GWAS on natural variation in endodermal suberin and had the privilege of naming it. For those interested, the study can be found here: www.nature.com/articles/s41...

A race people should be paying attention to is Superintendent of Public Instruction — basically the schools chief for the entire state. Sonja Shaw is currently leading. (It'll go to a runoff, but this is not a result I was expecting.) Read more about her here: edsource.org/2026/sonja-s...

Exciting time!🔬🔬🔬 My lab has started the week-long hands-on Quantitative Microscopy Workshop from today. We have 10-15 graduate students from 5-6 labs of UBC Botany are participating the workshop this summer. Each of my grad students are leading at least one session on your expertise area.

I’m excited to share that the article I wrote with Dr. Dawn Nagel for The Plant Cell journal is finally available! In this letter, I explored how scientific identity development in academia can explain differences in experiences for marginalized scientists. academic.oup.com/plcell/advan...

This spring I took over and redesigned the only Gen Ed on plants here #IB103. We walked through every core aspect of plant bio in lectures & labs, but also through art & design. I had a blast, the evaluations are rewarding (4.9/5), the redesign got an award from the college, and a little press too!

Russell Vought, Director of the OMB, has issued a set of proposed changes that would dramatically alter federal grant funding. However, we can each take action to prevent these from taking effect. Here's how, a 🧵 🧪 1/n www.science.org/content/arti...

While regulations.gov incorrectly lists this action as "closed for comments", you can submit your comments directly here: www.regulations.gov/commenton/OM... My response is below, but don't feel that you need to draft anything nearly so long-winded. A short statement will also be very helpful.

🪼 Your tax dollars paid a scientist to squeeze jellyfish through cheesecloth. Osamu Shimomura processed tens of thousands on an NSF grant to understand why they glow. He found a protein that glowed green under UV light. Called it "green protein." Nobody cared. For decades.

Turns out that symmetric and asymmetric divisions are broken in different ways in maize katanin mutants: symmetric divisions are misoriented because the PPB is in the wrong place while in asym divs, the PPB is poorly formed. www.biorxiv.org/content/10.6... with Steph Martinez 🧪🔬🌽

At some point we have forgotten that there must be a social contract and we as reviewers, readers and colleagues expect a bare minimum, default of truthfulness, correctness and collegiality. Otherwise, we're not doing science anymore 🧪

Do I make you look at the Sulphur Buckwheat every single time I do these posts? Yes. Am I going to stop? No.
