🧠 Does AI make biased medical choices?
A new study shows that models like GPT-4 show biases in medical decisions. For example, they recommended surgery more often when survival rates were emphasised (75%) compared to death rates (12%).

This is quite an assemblage of bones. I've never heard of anything like it from the Bronze Age. 🏺🧪
4,000-year-old bones reveal 'unprecedented' violence — tongue removal, cannibalism and evisceration in Bronze Age Britain
The extremely violent treatment of the corpses of at least 37 Bronze Age people is rewriting the history of prehistoric Britain.

This animation shows two massive black holes in the OJ 287 galaxy. The smaller #blackhole orbits the larger one, which remains stationary in the animation and is surrounded by a disk of gas. When the smaller #blackhole crashes through the disk, it produces a flare brighter than 1 trillion stars.

This study shows that spike sequences carry information beyond what rates and latency to first spike do:

My reactions:
1) Cool to see this in humans.
2) Are people still surprised that spike times carry information beyond rates/first-spike latency?!?!?!

The website vs app split for Bluesky vs Threads captures the difference in user base and usage patterns beautifully.
Bluesky = knowledge sector workers who have it open all day in a tab next to their emails. “Wait what was I doing again?”
Threads = normies watching recipe videos on the commute.
