We are really proud of this report from our 3 colloquia convened by the AAM and supported by the Moore Foundation. A few experts even said they would use it as their introductory textbook for this area. Please check it out!

For ASBMB 2026, each meeting day will have a "theme" organized by session chairs. "Is anyone there?" covers biological communication and interactions across the molecular, cellular, and organismal scales. Eric Betzig will be the keynote and sessions will be lead by Phil Cole and Graham Johnson.
Eric Betzig headlines the #ASBMB26 Deep Dive "Is anyone there? Information transfer in biology from proteins to organisms," exploring how life senses signals & changes the responses of individual proteins or the behaviors of whole animals.

Important piece from Sarah Stanley at Berkeley on new NIH definitions that can be construed to arbitrarily halt research that is both safe and important to public health and future cures www.statnews.com/2025/10/06/g... via @statnews.com
The NIH ordered me to stop my ‘dangerous’ gain-of-function research. It isn’t dangerous at all
Safe gain-of-function research is necessary to identify new treatments for diseases like for tuberculosis — but the NIH has imposed unfounded stops.
