A researcher at The University of Osaka has proposed a thermodynamic framework for describing hysteresis in solids, a history-dependent phenomenon widely used in memory devices, energy conversion materials, and other technologies. The study shows that hysteresis can, in principle, be described within thermodynamics when the state of a solid is defined not only by conventional variables such as temperature and volume, but also by its atomic configuration. By identifying the time-averaged equilibrium positions of atoms as essential state variables, the work provides a more rigorous theoretical foundation for understanding and developing solid-state materials that rely on hysteresis.

- A heart attack not only damages the cardiovascular system but can trigger toxic chain reaction linked to depression & anxiety - Identification of methylglyoxal (MG) molecule build up in certain parts of brain following heart attack can be linked to mood and cognition. - Research team has developed a peptide therapeutic that can trap MG to prevent it from damaging cells.

Researchers found that a small change in 3D-printing settings can help produce better-fitting permanent dental crowns. Crowns printed at moderate angles performed best overall. Thinner layers improved accuracy and fit, while thicker layers produced more consistent results across repeated prints.

A new international study quantifies, for the first time, how data losses in ocean monitoring would severely degrade the ocean heat estimates that underpin weather prediction, El Niño forecasting, and fisheries management.
