Here is Petra testing her bee 🐝 cage experiment to assess biomiticide peptide against varroa mites as an alternative to chemical pesticides 🤩 Thanks to Project Apis m. for the support! @CornellAgriTech @CornellCALS @CornellEnto

Our paper on using #eDNA from rainwater to study hidden biodiversity in #tropical #forest #canopies is now out in Science Advances! This method is a major step forward for the study and #conservation of this inaccessible compartiment. www.science.org/doi/10.1126/... Photo: J. Raynaud

With a few chemical tweaks to a known metal-organic framework (MOF), researchers have developed a material that quickly detects and removes a common per- and polyfluoroalkyl substance (PFAS) from contaminated water. cen.acs.org/environment/... #chemsky 🧪

Very excited about this paper led by Erika Castro. She has shown that Heliconius were ancestrally plastic in how they acquired their cyanogens, but some species have lost the ability to biosynthesise toxins, and have lost genes involved www.biorxiv.org/content/10.1...

Researchers have mapped the chemical pathway for 4-vinylanisole that causes locusts to swarm and figured out how to inhibit it: cen.acs.org/biological-c... #chemsky 🧪

Excited to head to #Evol2025 next week! It will be my last year in a presidential role for The Society of Systematic Biologists @systbiol.bsky.social and as such I will be giving the SSB Presidential Address. www.evolutionmeetings.org/plenaries.html

A coalition of 36 chemistry department chairs from US universities has published an open letter in Science highlighting their concern over recent federal policy decisions impacting science. cen.acs.org/policy/resea... #chemsky 🧪

Thread with an email being sent to @asn-amnat.bsky.social @sse-evolution.bsky.social @systbiol.bsky.social members today calling for a Tri-society week of action for NSF: Dear members: The tri-societies (ASN, SSE,SSB) are running a ‘Week of Action for NSF’. Your engagement is crucial.

I did a podcast interview for Voyage to the Wild with Charlie Young about Ants in the Amazon! You can listen to it here: podcasts.apple.com/gb/podcast/a...

Remember when you first learned about genetics at school? All those fascinating examples of human traits that are each apparently determined by just a single gene? Time to check in on some of your favourites to see how they’re doing. 🧬🧵🧪 1/n

I am so excited about this upcoming publication about the Bees of Pennsylvania! 🐝 Stay tuned; we will have a page online where you can purchase this book in July! @nashturley.bsky.social @napoleonicento.bsky.social @stephanidae.bsky.social

Kicking off my Bluesky account by sharing a new review I wrote with @lindymcbr.bsky.social for @currentbiology.bsky.social! If you’ve ever wondered about the source of your stank or just want to learn why humans smell weird (it's true!), then this review is for you! 👃🧪🤔 doi.org/10.1016/j.cu...

Published an op-ed for @cnn.com: “Nobel laureate: I owe America my success. Today, its scientific future is in danger.” A personal reflection on what’s at stake as science funding gets slashed. I’d be grateful if you could amplify both in and beyond the science world. www.cnn.com/2025/04/09/h...

I may be tired and a little hoarse, but as I said again and again on the Senate floor, this is a moment where we cannot afford to be silent, when we must speak up.

“What does that 🐶 smell that I don’t?” Analytical chemistry has methods to find an answer. In this case, scientists are looking for the chemical compounds responsible for the smell of powdery mildew on grapevines. 🍇 buff.ly/RjJr7kH

It’s an honor to receive the ACS Chem Biol Young Investigator Award! I’m most grateful for the contributions from all past & present lab members — it is an award for all of you as much as for me.

@CornellAgriTech campus wide breakfast 😆 Amazing community of food scientists, entomologists, plant pathologists, horticultural scientists 🤩

Pleased to share a new article from my Phd student Jorge Ruiz-Arocho that examines how #cropdomestication and #nitrogen #fertilization affects #leaf traits for #maize, #beans, and #squash. link.springer.com/article/10.1...

New study out from my group showing how the volatile geosmin (the wonderful 'smell of dirt') serves as a cue to influence the behavior of soil protists rdcu.be/edCJj

Just heard that Trump is putting an end to atmospheric monitoring site NY67 that is run out of my lab. This is one of the oldest NADP sites in the US, continually measuring acid rain and other pollutants since 1977. Closing it down is tragic.

Why all media are silent about the attack on higher education and science? People should know that US science innovation is at risk of collapsing! @ahmedbaba.bsky.social

Porkchop and Peanut dog fight (kind of lazy and totally inefficient 🤣)

It was amazing to have Professor Raychelle Burks give a lecture on my campus yesterday!

The crisis in higher education and science (I mean the attack we're under) is worse than the Covid crisis .... even in Fall 2020 we didn’t stop recruiting grad students 😞

We got the cover of Nature Eco Evo for our anglerfish study!! Shoutout to our graduate student HoWan Chan for the slick image. Read to study here www.nature.com/articles/s41...

Hi BlueSkyers! I'm an evolutionary biologist, microbiologist, entomologist, lover of nature, and long-time researcher on symbiosis. I'm realizing that BlueSky is useful and generally non-toxic so here I am (having quit Facebook in Jan 2017, and Twitter in Oct 2022).

NSF plans to reinstate all probationary employees who were fired on 18 Feb! NSF’s decision. 👏🏻👏🏻❤️

I am thrilled that this study by my former PhD student and current postdoc Chrisin Walther is now published in Ecology Letters! Congratulations Tine!!! onlinelibrary.wiley.com/doi/10.1111/...

It’s official, 2024 was the worst year for bumblebees since records began🚨 The latest findings from #BeeWalk, the national bumblebee monitoring scheme, have revealed bumblebee numbers declined by almost a quarter (22.5%) across Great Britain💔 www.bumblebeeconservation.org/british-bumb...

Using Bayesian neural networks and evolutionary modelling, we show that trophallaxis evolved twice in ants: 130 million years ago when flowering plants became more abundant and ants began harvesting sugary liquids from plants and their insect partners, and again in others ~90 million years ago.

Just got word that our Howard Hughes Medical Institute (HHMI) Inclusive Excellence 3 (IE3) Grant was being canceled. All 100+ institutions. So even private funding is susceptible to this administration’s unraveling of DEI initiatives

This new paper looks amazing (and the title is pretty cool) www.biorxiv.org/content/10.1...

NASA did a feature on me last year. It was up this weekend but now when you click on the link you get a 404 message.
