Welcome to 'Collectivity in living systems'! During the next few days we'll explore coordination, cooperation, emergence, and decision-making in systems ranging from bacterial biofilms and cell migration to tissue formation, disease models, and animal behaviour. Let's go! πŸ™Œ #EESCollectivity

Our cells are experts at navigating inherently noisy and complicated environments.

EMBL researchers are using theoretical physics approaches to uncover fundamental principles behind how cells use complex information to self-organise.

Professor Sir John Gurdon FRS (1933-2025) | Magdalene College Magdalene College is deeply saddened to announce the death of Professor Sir John Gurdon FRS, who served as Master of the College from 1995 to 2002.

Very sad news, John Gurdon has died.

A developmental biologist's developmental biologist, Nobel prize winner

His work is the foundation of much of today's dev & stem cell bio.

An inspiration to many, including me. Always asking questions & wanting the answers

A plot showing the duration of the early embryonic cell cycle of 5 different species as a function of temperature. Higher temperatures mean faster cycles, up to an optimum, beyond which the cycles slow down and eventually stop.

A plot showing the duration of the early embryonic cell cycle of 5 different species as a function of temperature. Higher temperatures mean faster cycles, up to an optimum, beyond which the cycles slow down and eventually stop.

Many years in the making but now finally online! What determines the temperature scaling and thermal limits of cell cycle duration in embryos? We tackled the question using a combination of dynamical systems analysis and experimental measurements in embryos and in cycling Xenopus extracts.
