the current NZ govt is so anti-science that they've changed eligibility for the Prime Minister's Science Prizes to rule out awards to people doing basic science eg from 2026 the MacDiarmid is for work with "potential to generate econ, health, social, or env benefits for New Zealand" #nzpol

1. A bit of evolutionary biology. I'm really intrigued by a new perspective piece from Steve Frank that explores connections between how natural selection creates systems that generalize and recent work in machine learning about the surprising capabilities of massively overparameterized systems.

Generalization as the great leap in evolvability: insights from machine learning

Abstract. Natural selection encodes learned information in the genome. Learned solutions may be tuned specifically to past challenges, failing in altered e

In our new study we were the first to experimentally simulate the origin of sociality! By controlling how many wasp 🐝daughters could help their mom, we found that early helpers don't just add to colony success—they multiply it!

"are you enjoying duo mobile" does a hamburger enjoy being made of quarks. does a fish enjoy linear time. does the mountain enjoy the first taste of a cup of hot chocolate when you get back to the ski lodge. your question means nothing to me. i couldn't enjoy duo mobile even if i tried

Does anyone have a favorite experimental evolution overview for undergraduates? Ideally one that goes into the details of fitness assays, marking strains, etc. Everything I’ve found doesn’t dig into the details sufficiently.

David became a freelance bioinformatician due to the situation he describes 👇. Freelance workers are typically looking for the next contract. That's how it is. Maybe we could boost this signal so that people who appreciate David's experience and principles can find him?

I was made redundant from a decade-long bioinformatics job, in part, because my new boss thought that LLMs and similar technologies were better than an experienced bioinformatician who encouraged FAIR principles and discouraged abusive behaviour.

These are the beautiful spore-producing structures of plasmodial slime molds. Which is your favourite colour? Originally considered Fungi, they are now classed as Ameobozoans - single celled organisms with thousands of nuclei... not animals or fungi but something else entirely! #SoilBiodiversity 🧪

☔💦 Sun, Sep 21 A sublime summery 8 days it's been w/J pod inland Puget Sound. Especially wild their South Sound foray, their first in decades. Orcas reported this morn in Admiralty Inlet. Is it Js leaving? 📸 J pod Double spyhop! Taken from atop Tacoma Narrows Bridge. By Jolena Tagg 9/20. #psws

There's always something new to see. This absolutely wild little thing is the insect-egg slime mould (Leocarpus fragilis). Each fruiting body is about 1.5 mm long. Bob Orr Pond Trail, Caughey-Taylor Preserve (Nature Trust NB), near St. Andrews, New Brunswick.

Closeup of a slime mold on a small log. The slime mold is fruiting, with  hundreds of small oblong red-orange fruits. Each is about the shape of a Tic-Tac, but only about 1.5 mm long. They are coming from the remnants of a silvery-grey reticulated plasmodium.
