Excited to share this perspective article from my group - how can the interactions between microbes shape the spread of antibiotic resistance mutations? Thank you @microbiologysociety.org for inviting us to submit this 🦠 www.microbiologyresearch.org/content/jour...

Microbial interactions as key players shaping the emergence and spread of de novo resistance mutations

Antibiotic resistance and the microbiome are two of the most prominent and highly active research areas currently in microbiology. However, these studies are commonly siloed. Research into antibiotic ...

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/...

Balanced polymorphism in a floral transcription factor underlies the ancient rhythm of daily sex alternation in avocado | PNAS

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.

People. @ksamuk.bsky.social and others have made this argument before. There’s good software to do this right. Here’s the argument again: Invariant sites matter! They’re not in your standard vcf and many programs pretend they are anyway. academic.oup.com/gbe/article/...

🪼 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.

Some reflections on #Fungal26 This was a great meeting as always but set against some turbulent times of course, which meant many regular attendees were not present. This thread is mainly for them. However, the proportion of first-time attendees was very high and very international. #Fungal26 1/15

Thrilled that work from collaborative efforts by the @dbensasson.bsky.social & @mcmomany.bsky.social labs has been accepted by G3 and is available to read now! Population geneticists beware - low-level contamination has greater impact on analyses than you might expect. doi.org/10.1093/g3jo...

A new paper and video about levels of drug resistance in different countries

I am so happy to share a new paper and a new video (see below). The paper describes a simple mathematical model that describes levels of drug resistance. I called the model the Resistance-Acquisition-Purifying-Selection model (RAPS). While the model is simple, it wasn't easy to write the paper or to get it published. Before submitting to the journal Epidemics, I submitted to Nature (desk reject, late 2023), Science (reject after useful reviews, early 2024) and PNAS (another reject after constructive reviews, mid 2024).

Many US students don’t know how to seek opportunities outside the US. With some help from our colleagues in EU and Canada, we could put together a consolidated website of PhD opportunities and scholarships outside the US, organized by field. There might still be time for this year in some places.

I’m having similar conversations and sharing international opportunities a lot. I’m sure for a lot of US based trainees that feels overwhelming. I moved to Europe for my postdoc.Happy to chat with any trainees about my experience if it would be helpful.

This does away with awards based on underrepresentation, student support services based on race, scholarships, etc. Let me explain, pre coffee (wrote this morning, no time to update, you're getting a cut n paste), why this is a bad idea. 🧵 www.insidehighered.com/news/diversi...

In a sweeping and unprecedented letter issued over the weekend, the Office for Civil Rights declared race-based scholarships, cultural centers and even graduation ceremonies illegal.
