"Cancel ChatGPT" movement goes big after OpenAI's latest move After Anthropic refused flat out to agree to apply Claude AI to autonomous weapons and mass surveillance of American citizens, OpenAI jumps right into bed with the United States Department of War.

"Cancel ChatGPT" goes mainstream after Sam Altman takes the U.S. department of war deal Anthropic refused — in surveillance of U.S. citizens and autonomous weapons.

How do proteins really fold? Our latest @pubs.acs.org JPCL paper with @saureli.bsky.social @valeriorizzi.bsky.social @mheritier.bsky.social unveils a new MD strategy to investigate it in atomistic resolution by focusing on water and side-chain interactions. check it out pubs.acs.org/doi/10.1021/...

Enhanced Sampling and Tailored Collective Variables Yield Reproducible Free Energy Landscapes of Beta-1 Adrenergic Receptor Activation The beta-1 adrenergic receptor (ADRB1) is a critical target for cardiovascular drugs, yet our understanding of how it is activated remains incomplete. Capturing the concerted interplay of agonists, solvent, ions, and protein microswitches is a significant challenge for conventional simulation methods and is essential for unraveling this process. Here, we address this challenge by implementing a powerful enhanced sampling framework that integrates the OneOPES enhanced sampling algorithm with a set of biologically motivated collective variables (CVs). These CVs are designed to track several key features of the activation process simultaneously, including rearrangement of conserved microswitches, the state of the sodium ion binding pocket, and dynamics of critical water molecules. Using this framework, we mapped the multidimensional free energy landscapes of the ADRB1 receptor in both its apo- and adrenaline-bound holo states. Our analysis reveals a detailed, stepwise activation pathway that quantifies the known modulatory roles of sodium ions and protonation states and identifies essential water-mediated networks that stabilize the active conformation. This work provides a detailed overview of ADRB1 activation and establishes the robustness of our OneOPES approach for investigating complex activation mechanisms with the potential for application to other Class A GPCRs.

New in @pubs.acs.org JCTC: We've mapped the complete activation pathway of the β1-adrenergic receptor using our OneOPES enhanced sampling method and tailored CVs. Our approach reveals how sodium ions, water networks & protein microswitches work together. pubs.acs.org/doi/full/10.... #GPCR

How do nuclear membranes fuse during NPC assembly? We answer this question in our latest work, where we identify a new mechanism for membrane fusion… (1/13)

No, AlphaFold has not completely solved protein folding Biology is hard. Yes, even for AI.

AlphaFold is great, but contrary to public opinion it has not completely solved the protein folding problem. Much work remains to be done.
