Uncovering complementary information sharing in spider monkey collective foraging using higher-order spatial networks
Collectives are often able to process information in a distributed fashion, surpassing each individual member's processing capacity. In fission-fusion dynamics, where group members come together and s...

combined knowledge has complementarity: each individual fills in parts of the puzzle that others miss. We argue that the ever-changing structure of these groups helps them collectively adapt and make the most of their shared knowledge in unpredictable environments.

track changes in their environment better than any individual could on its own. We studied how much individual animals' core ranges overlap, treating these overlaps as a way to measure shared vs. unique knowledge of food sources. Some range combinations strike a balance: they have enough overlap

Groups can often process information together more effectively than any single member could alone. In species with fission-fusion dynamics—where animals frequently split up and reunite (like dolphins or chimpanzees)—sharing different bits of knowledge about food locations helps the whole group…

2025: Agency gained and lost
If you’ve had even a passing glance at tech journalism over the past few months, you know the top buzzword for AI in 2025 is agentic. Agentic AI (according to many think pieces and press releases a…

“We can also use theory to ask the following question: how might a biological system solve a particular problem?”

“We can also use theory to ask the following question: how might a biological system solve a particular problem?”
“for me as a biologist, theory is valuable because it enables us to ask which of our results are likely to be general and which depend on the particular characteristics of our experimental system.”
