1/10 How does a sperm whale hunt in darkness, hundreds of metres beneath the surface? Our new preprint reveals a two-level strategy: persistent search across whole dives, paired with rapid switching between distinct prey-capture tactics. Link in๐งต

What an exciting week at @netsciconf.bsky.social ! If you still have some curiosity left, stop by this afternoon. I'll be presenting, โToward Fairness in Network Algorithms: Rankings by Biased Random Walks.โ ๐ Where: Algorithms, Inference & Reconstruction 3 (Kendall Square) ๐ฐ๏ธ When: 5PM
Later today (3.45pm) Iโll be talking at the NSIA (network-science-ai.github.io/schedule.html) workshop of @netsciconf.bsky.social about (exciting!) work on the interplay between generalization and working memory limits. Come through!
There seems to be a broad perception across psychology and neuroscience that work shouldn't be "too technical" in order to reach the broadest possible audience. While I think we should strive for accessibility, I feel that this attitude can also be self-defeating: why are we dumbing down?

Very good article what it would take for AI to have "agency" and self-preservation goals (w/ a few quotes from me). & I appreciate the reiterated debunking of the "GPT-4 on its own lied to a TaskRabbit worker to solve a captcha" story. www.quantamagazine.org/why-do-we-te...

Our tales of AI developing the will to survive, commandeer resources, and manipulate people say more about us than they do about language models.

As Giovanni Petri shared with #NGN, sperm whales and humans have more in common than we think. Their coordinated support during a calfโs birth shows survival has driven strong social ties, even beyond kin. news.northeastern.edu/2026/03/26/s... @lordgrilo.bsky.social @projectceti.bsky.social
Whales display behavior typically seen in humans, new research shows
Scientists captured the first detailed footage of a sperm whale birth and found it was not just a family affair.
