Uniform, globally accepted greenness metrics are positioned as essential; inconsistent scoring frameworks would erode comparability and limit decision-making for method selection.

In a study published in PNAS, a research team developed a new reinforcement learning-based enhanced sampling method called Adaptive Collective Variables Generator (Adaptive CVgen), which has been ...

Many antineoplastics are designed to target upregulated genes, but quantifying upregulation in a single patient sample requires an appropriate set of samples for comparison. In cancer, the most ...

Heat treatment originated in the Bronze Age and was developed further for processing iron (blacksmithing) around 800 BC, reaching a first peak with the production of Damascus steel at the start of the ...
