Donald Trump wants to use your tax dollars to pay off January 6th rioters who beat cops with flag poles, and the GOP at large has nothing to say about it. They don't care, it's that simple.

Unrequited spider love This is a pair of flea jumping spiders (Naphrys pulex). I found the male first, on a pine tree, and he led me to the female. He was on the hunt for a mate, but she was more interested in a meal than company Ultimately, he lived to woo another day, so I'd still call it a win

Photo of two small spiders facing each other on a piece of pine tree bark. The upper left spider is the smaller male, and he is backing away from the female with his forelegs raised in what I assume is spider for, "I love you, please don't eat me!". The larger female is advancing from below. The scale of the bark makes it look like the spiders are standing on a rocky cliff or something, but actually they're just very small and it's tree bark.

Congratulations to @samjakeengland.bsky.social for his @currentbiology.bsky.social cover😍after @atal-pande.bsky.social's new paper! This leggy fren is a wolf spider (Pardosa) featuring in several projects in @multipleye-lab.bsky.social, so it's lovely to see her getting the limelight she deserves 💃

Arachnophobes, avert your eyes! NEW issue just dropped🕷️👇 www.cell.com/current-biol... As usual, casting a wide net, across all of biology!🧬 🕸️

It may be surprising to some that there are thousands of undescribed species just sitting in museums awaiting description. One of the main reasons this problem exists is that taxonomy is undervalued and underfunded, a trend that coincides with the devaluing of studies on natural history.

🌿🐙 I got back Friday after 5 days in Lincoln, NE, at the American Arachnological Society annual meeting. It was my first scientific conference. I have had a not-great 2026, and while some might not think a week full of spiders & scorpions would be good for the soul, it healed mine. To a person--

Yesterday the US Administration supercharged its explicit effort to bar international students from staying in the US after graduation. All Americans should know: 1/3 of *all* STEM PhDs working in the US are immigrants who graduated from US universities, then stayed. www.piie.com/index%2Ephp/...

Hey team - it’s looking very likely that I’ll be hiring not one but two four year postdocs! We’re a fun lab with tons of theoretical and applied pop gen projects - broadly in polyploid, conservation, and human evo. Competitive salary, sunny San Diego! Do share with your about to defend grads!

was happy to get this close to a flower-visiting Ammophila ... I typically find them quite fast & skittish around flowers check the excellent brushes on leg I, for their nests in often sandy soils 5 eyes, come on now ....
