📢 A team led by Seigo Shima has revealed that #methane producing #microbes can reduce their need for #nickel when levels are low. The study sheds new light on the ecology of #methanogens and their impact on #climatechange. https://t.co/JHCauzQkCU

Amazing work by Olivia Pfeil-Gardiner @zoliviapg et al. from the @_Murphy_Lab! Using STEM-EELS, they mapped specific elements within protein structures, demonstrating the power of *reconstructed electron energy-loss (REEL)* analysis. 👀👉 https://t.co/sf1is59rsJ

There we go🤷. We have #alphafold3, @alexjamesnoble's VirtualIce, a plethora of (nearly) automated 3D reconstruction tools, #ModelAngelo... and AIs that can generate hypotheses, test them and write papers. #cryoEM can go home I guess.
In two new papers, researchers present AI agents that can do the entire job of a scientist – from hypothesis formulation, to literature research, data collection and analysis, all the way to writing a paper. https://t.co/pPG8Rt8T0H

Our elemental mapping work, combining cryo-EM and EELS to REEL analysis, is now also published on Nature Methods: https://t.co/Yf3UGSGSWe For a highlight “reel”, see here 👇
Happy to announce that our efforts to establish elemental mapping for cryo-EM ❄️ by EELS 🌈 are now shared on bioRxiv: https://t.co/hCTHQCyxN4 Congratulations to @zoliviapg and co-authors! But wait - Can we map elements in 3D? 🧵👇 1/6

Much of the success of breakthroughs, such as AlphaFold, is thanks to a database of protein structures dreamed up in the 1960s by Helen Berman
nature.com
Nature - Pioneering crystallographer Helen Berman helped to set up the massive collection of protein structures that underpins the Nobel-prize-winning tool’s success.
