Researchers cast neural nets to simulate molecular motion

New work from Los Alamos National Laboratory, the University of North Carolina at Chapel Hill, and the University of Florida is showing that artificial neural nets can be trained to encode quantum mechanical laws to describe the motions of molecules, supercharging simulations potentially across a broad range of fields.

Tracking down dark matter

Matter surrounds us day and night in all its forms—trees, houses, furniture, and even the air we breathe. But, according to physicists, the visible matter familiar to us may only account for approximately 20 percent of all material in the universe. According to the current theory, as much as 80 percent may be dark matter. This claim is based on several observations, one of which is that stars and galaxies rotate much faster than they would if there were only 'normal' matter present in the universe.

A counterintuitive case in which like charges attract

When it comes to electric charge, there is one overriding theme: opposites attract, and like charges repel. But in a new study, physicists have made the surprising discovery that two spherical like-charged metal nanoparticles with unequal charges can attract one another in a dilute electrolyte solution. The reason, in short, is that the more strongly charged nanoparticle polarizes the metal core of the weakly charged nanoparticle, which alters the interaction between the nanoparticles.

Transformer cells: Shaping cellular 'behaviour'

Scientists from Sechenov University, conjointly with their fellow Chinese and American researchers, have examined the latest advances in the use of skeletal muscle progenitor cells, specifying the core challenges inherent to the applicability of MPCs in cell therapy, and outlining the most promising breakthrough technologies. The outcomes of this research were reported in Applied Physics Reviews, the article having been roundly praised by the editorial board.
