The comparison is part of the discovery
Good controls deserve some of the attention usually reserved for ingenious models. Mira introduces an issue about evidence that helps a scientist decide.

Research reviews
What a formulation robot can learn from yesterday’s experiments
An evidence-ablation experiment makes a persuasive case for laboratory memory—while matched campaigns reveal why the best sample is only part of the result.
What a reversed sequence can teach a molecular model
An unreviewed study finds that structured practice before chemical training can improve property prediction. Its controls show why the benefit depends on more than extra training.
Teaching a phase map to respond to pressure
Exponentially tilted thermodynamic maps make environmental controls part of a generative model. Their practical promise becomes clearer when the reference simulation, sampled observable and computing budget stay in view.
What counts as progress when small changes already work?
A measured survey of close analogues gives AI-assisted medicinal chemistry a tougher comparator: accessible chemistry can improve potency while exposure properties move the other way.
What an organ-targeting model actually predicts
An interpretable lipid-nanoparticle classifier offers useful formulation hypotheses. Its outcome label and validation design determine how far they travel.
