A gathering of marine reptiles (Helveticosaurus zollingeri) lie on exposed rocks within a sea cave. Foamy sea water rushes in from the left, swirling beneath their perch.

ICYMI, here is the press release for my study with @drjuliawester.bsky.social - we surveyed over 800 scientists who use social media. They overwhelmingly agree that Twitter is no longer useful or pleasant, and that for all professional online scientist goals, Bluesky is superior.

Michael Gove admits that post-Brexit trade deals were bad for farmers Michael Gove has admitted for the first time that the Australia and New Zealand trade deals negotiated by the former Tory government did not protect Britain’s farmers.

This deserves more attention than it has received.

Gove: "we were too anxious as a government to secure those deals in order to show that Brexit was working".

Exactly as so many of us warned at the time, and as the government denied at the time.

It’s Blondie, a beautiful Nile crocodile!

I’ve seen yellow reptiles like this often referred to as xanthic. Mutation? Polygenic morph? Anyone know more?

A photo of a blue spotted stingray. The animal is a dark greenish gray with a multitude of vibrant blue spots. Its body is flat and pancake-shaped.

A photo of a blue spotted stingray. The animal is a dark greenish gray with a multitude of vibrant blue spots. Its body is flat and pancake-shaped.

Behold the striking colors of the blue-spotted stingray! Its bright spots are a warning to onlookers that it's venomous—& if its colors aren’t enough to ward off foes, it’s equipped w/ a tail that can inject a lethal dose of toxins.

Excited to share our research on the evolution of fossil forests from the Devonian to Jurassic! By analyzing 38 global fossil forests, we explored key parameters to better understand how these fossil forests developed over time.

This patient’s Neuralink brain implant gets a boost from generative AI A patient who types with his brain thanks to a Neuralink implant is using AI chatbots to speed things up.

Can not stop thinking about the philosophical/existential implications of this.

When you are constantly being offered suggestions for your thoughts, when do you stop being you, and just become an interface for the AI.

Let’s set aside the question of whether these edited animals *are* the species they’re claimed to be - what possible argument would there BE for releasing them into a wild that isn’t the ecosystem they went extinct from? It would likely be condemning behaviorally-unequipped animals to slow death.
