@hywan@floss.social This + the final statement of proposal A : " Debian is not here to generate as much code as possible requiring manual review by a shrinking number of human volunteers, or to package every piece of software, or to rush new features, but these are what LLMs are used for. " could readily be applied e.g. to scientific research. "/Universities/ are not here to generate as much /papers/ as possible requiring manual review by a shrinking number of /human researchers/" ...! #AI #MastodonScience #AIinResearch #LLM

"The arrival of #machineLearning approaches that predict cellular behavior at scale and integrate a wide array of #biologicalData types makes the analytical demand on #mechanisticModels even more pressing. Prediction is increasingly available without #mechanistic #understanding. The central challenge is no longer building models that reproduce #biological behavior, but building #models from which causal structure can be inferred."

#theGuardian embraces the #allOrganoids narrative.

I'm not the best person to comment, but I believe this conjunction of over-enthusiasm for #organoids and of anti #animalResearch is problematic.

Brilliant that @eLife is here! About the new publishing model, there's at least one thread already, https://mastodon.social/@AllenNeuroLab/109302451546531877

Short-range electrostatic screening in ionic liquids as inferred by direct force measurements In the last decade, conflicting experimental reports of long-range interactions in #ionicLiquids (ILs) and concentrated #electrolytes have puzzled theory and numerical simulations. The discrepancy lies in nonequilibrium effects as evidenced by our rigorous measurement protocols using complementary advanced Surface Force Apparatuses. ILs screening is genuinely short-range under conditions approaching thermodynamic equilibrium. Their decay lengths (~0.5 nm) match the theoretical predictions. Conversely the further from equilibrium the larger interaction extents. These arise from background drift rates with various relaxations spanning two orders of magnitude in time scale. The IL behavior is reminiscent of slow relaxation dynamics in glasses, thin polymer films, historical paintings, and granular media. https://www.pnas.org/doi/10.1073/pnas.2517939123
