Good news- the #LagoLab is at a steady state! Incoming grad student @ca-haus.bsky.social moved into Baton Rouge yesterday. He’ll be at #Botany2026 too! 🎉 Campbell will be the first grad student who doesn’t have any overlap with my first grad students. A true generational turnover 😭.

After seven fun, productive years as a #LagoLab PhD student, @laymonstera.bsky.social is off to a postdoc Berkeley with Sarah Kocher. I’m going to miss her but she’s so ready for her career ahead!! (We’d all be crying in this goodbye photo if we weren’t going to see her on Sunday at #botany2026 😅)

Avocados come in 2 varieties - A-types start each day female and switch to male midday. B-types do the reverse. In work just published from the last chapter of my PhD, we show this system evolved 40+million yrs ago and is regulated by alleles of 1 transcription factor www.pnas.org/doi/10.1073/...

In avocado and certain wild relatives in Lauraceae, a highly synchronized daily rhythm of floral sex timing promotes cross-pollination between two ...

From the abstract: “promoting a woman to Associate Professor increases female faculty by 1.5 members after 15 years, leads to six additional female PhD graduates over the following decade, and raises the number who subsequently remain in academia and reach tenured positions”

Fascinating paper on the progression of women in academia. 👩🏻‍🔬 ⚛️ 🧪 #AcademicSky docs.iza.org/dp18477.pdf?... Here's an excerpt from the conclusion:

When women do obtain tenure, the effects extend well beyond their own careers. Beyond the direct promotion of the qualifying candidate, departments experience on average one additional female promotion over the subsequent fifteen years, a substantial expansion of the female PhD pipeline, and improved retention and career progression among female doctoral graduates. These effects are concentrated in departments where women are underrepresented, but not entirely absent, suggesting that a minimal female presence is a precondition for trickle-down effects to materialize, whether through mutual support, departmental influence, or other channels that require women not to be entirely isolated.

Do dogs need glasses? Most dogs have 20/75 vision, seeing at 20 feet what a human can see at 75 ft. Not great. But would they benefit from corrective lenses? The answer is: probably not. Let's talk about the good & bad of 'dog-o-vision'.

Alt: Smart Dog Wearing Glasses: a black Labrador retriever (I think?) wearing a human pair of glasses suddenly reacts with alarm to something off-camera. It's in a generic home or apartment with tan carpet and white walls, with vertical blinds over a window.

There are many comments up on the OMB rule but there are now many that claim to be in favor of the rule and they are well written and anonymous- claiming to be tenured professors worried about waste fraud and abuse. We need as many real, unique comments as possible that show how bad this rule is

There's an OMB rule change that would require political oversight of scientific grants, and could pull any that don't "reflect presidential priorities" Another country has tried this before! It was the USSR and it was called Lysenkoism. By @thsaey.bsky.social www.sciencenews.org/article/omb-...
