The bite of sicariid spiders such as the brown recluse can cause tissue necrosis. Crystal structures of the Chilean six-eyed sand spider’s venom toxin reveal how the toxin breaks apart cells—information that could help develop treatments. In PNAS: https://ow.ly/u5aw50YFJlR
Na 1ª Conferência #FAPESP 2026, “Por um #Museu Comprometido”, Aurélie Clemente-Ruiz, diretora do @museedelhomme.fr, sustentou que essas instituições culturais precisam ir além da conservação e assumir papel ativo nos debates contemporâneos. agencia.fapesp.br/57615
Exciting times ahead - I'm beyond delighted to be joining @bristolbiosci.bsky.social in 2026! 🎉🕷️🎉🐌🎉
I'm also looking for a PhD student to join @multipleye-lab.bsky.social in our new home! Come and study the effects of light pollution on the evolution and development of spider eyes with us 🌃🕷️👀 👇
A brown pseudoscopion hanging on to the antenna of a wasp. The wasp is yellow with black stripes and transparent wings.
My first pseudoscorpion observation was pure luck. Happen to see this wasp and took a shot. It was only later did I see what was hanging on the antenna.

That's cool! Have you ever tried scanning without drying, in a liquid medium? Perhaps for comparison purposes?
#microCT scan of the left palpal bulb (male copulatory organ) of a grass spider I found wandering Beckman's hallways last week! 😍(He was on his last legs when he was preserved for the scan). Taken in the Microscopy Suite of @beckmanillinois.bsky.social and rendered in the Visualization Lab.
We love jumping spiders because they are smol, cute, active, friendly and always looking around curiously with their huge eyes. But do you know they’re also masters of mimicry? Check out the bugs they pretend to be (and some of those are really good)!💚💚

Panels one and two: Two white mice make their way through a maze. Panel three: Having completed the maze, the two mice are rewarded with some fruit. Two scientists watch them. One says: “Poor little things: all that thought and effort just to earn themselves a little treat.” The second scientist looks at a clock and says: “Coffee time!” Panels four and five: The two scientists make their way through a maze of corridors to a door marked “Canteen” Panel six: The scientists look at the food on offer. One says: “Ooh, Donuts!”

Our arachno-colleague, Dr. Peter Jaeger, has the ambitious goal of running an inclusive and low-budget scientific conference: the Asian Conference of Arachnology (ACA) 2025.
All donations will cover travel and conference expenses for students and ECR from low-income regions in Asia.

The curious morphology of the treehoppers can help them detect different electrical charges and even distinguish friend from foe. Excellent work!
This is one of the coolest things I've ever read!
I watched an online talk you gave on this topic some time ago and had been looking forward to seeing the final paper. Excellent work with a fantastic group! I find them bizarrely charismatic 😆. I loved everything about it!
It's so great to see the interdisciplinarity of science.
Congratulations!
Obrigada por compartilhar @atila.bsky.social ! Foi bem legal fazer esse trabalho :)
Thank you, Sebastian!
The paper uniquely compiles photos and videos about the species' behavior.

@cesarfavacho.bsky.social and I made a video to present the results of our recently published paper on Tapixaua callida (subtitles in PT and EN). This fascinating spider mimics ants in a way very similar to the Asian species Pranburia mahannopi, described by arachnologist Christa Deeleman-Reinhold.
🕷️🌍🕸️ Spiders aren't creepy crawlies—they're ecosystem heroes! From pest control to biotech inspiration to key figures in our collective culture, a new review reveals the many services spiders provide:

I had a lot of fun giving this interview - I wish my research always had dramatic music in the background
Caterpillars can sense predators before contact – by detecting their electric fields! 🐛
Recent @pnas.org study led by @samjakeengland.bsky.social won the Cozzarelli Prize. Congrats, Sam – brilliant work on insect electroreception! 🎉

A circular illustration of 19 colorful different species of invertebrates across various phyla (arthropods, cnidarians, echinoderms, sponges, mollusks, annelids, flatworms). Black arching text surrounding them reads “Celebrate Invertebrate Biodiversity”. They are illustrated on a light blue background.
Happy #Invertefest! Celebrate invertebrate biodiversity 🐛💕

Arthropod decline, particularly in cities, has devastating consequences for predators. Consequently, globally invasive urban spiders are well adapted to long-term starvation (>42 weeks), as demonstrated in my first paper since my PhD. @cp-iscience.bsky.social
doi.org/10.1016/j.isci.2024.110722
The adaptation of these spiders to periods of starvation is impressive. Congrats on the paper, very interesting :)
How cool!
