Thanks to Crick Science Entrepreneur Network (CSEN), the Crick's Innovation and Business Office and the Flagship Pioneering UK team, especially Junaid Bajwa and Sutha Satkunarajah for making this possible.

🧬 I’m also very much looking forward to welcoming the Flagship Pioneering team to the Crick, showing them our labs, and building exciting new partnerships through this Flagship–Crick talent exchange.

🎓main focus: Flagship’s Boston-based, paid summer fellowship (June-August 2026), aimed at entrepreneurial PhD students and postdocs worldwide. Hear from Justine Levin-Allerhand and get first-hand perspectives from alumni & mentors Lena Afeyan PhD MBA, Simon Brunner, Reza Rohani and Adiyant Lamba PhD

Flagship Pioneering Summer Fellowship 2026 - Info Session · Luma What if...there were an apprenticeship for scientific imagination?  Are you a bold, creative scientist ready to spend a summer learning how world-changing…

An exciting event this week, words from my group leader Rado Enchev:

📣 Thrilled to be co-moderating a Flagship Pioneering info session at The Francis Crick Institute on Thursday 11 December, open to anyone curious about venture creation
 
👉 Everyone invited but spaces limited: luma.com/qk6ymc1y

Do you think this could work for small domains on larger proteins/complexes?

A big thanks to Jose Maria Carazo and Carlos Oscar Sorzano for their amazing guidance and support throughout this project and my Marie Curie fellowship generally

And thanks to MRC LMB scientific computing and funders MRC, Horizon EU and CSIC

Thanks and congratulations to all authors: Aditya Pokharna, Imogen Stockwell, Josip Ivica, Bishal Singh, Johannes Schwab, Carlos Vega-Gutierrez, Ondrej Cais, Beatriz Herguedas, and Ingo Greger

We used a combination of Cryo-EM and simulations, including classical MD and metadynamics, along with electrophysiology for kinetics and synaptic targeting

Our new paper in Nature provides a structural framework for GluA3, a disease-prone AMPA glutamate receptors - previously unseen interfaces offer sites for drug development: www.nature.com/articles/s41...

Some amino acid changes can happen with just one nucleotide change but not all of them. A 2-nucleotide mutation is one where 2 nucleotides of the three encoding that amino acid undergo changes and that’s rarer

I imagine we could have a mechanism of having pull requests that get reviewed?

It’s fine to discuss things in a constructive way. The comment of yours that I contradicted is the one where you said people don’t care

We are the scientists/professionals talking to each other. If you don’t care then don’t follow us.

Where does the specificity for cancer cells come from?

(3) This paper is now out for review again (woo!); if you have read this and received it to review - please consider writing your review in light of our response to reviewers!

(2) Further, @fraserlab.bsky.social conducted a great public peer review of this (thanks Daphne, CJ, and Jamie)! We want to respond to their comments, as well as some replies to our original reviewers. This response-to-reviewers can be found here: www.dropbox.com/scl/fi/v5iqy...

RCSB PDB - 8DE9: Cryo-EM structure of the zebrafish two pore domain K+ channel TREK1 (K2P2.1) in DDM/POPE mixed micelles Cryo-EM structure of the zebrafish two pore domain K+ channel TREK1 (K2P2.1) in DDM/POPE mixed micelles

There are definitely automated solutions. Andreas Engel, Luca Rima and Thomas Braun have an interesting one that was described in www.pnas.org/doi/full/10.... from 2019 and probably better now. It uses a UV cleavable linker to elute from the beads and is all coupled into a robotic system

Can I be included please

How do we use these? It doesn’t work for me

Thank you!

I’m a research fellow in computational biology. I use molecular dynamics simulations, normal mode analysis and cryoem to study protein dynamics. I develop methods and study particular proteins, especially AMPA ionotropic glutamate receptors (#neuroskyence) and SARS-CoV-2 spikes (covid)
