'Marshmallow' world orbiting a cool red dwarf star

A gas giant exoplanet with the density of a marshmallow has been detected in orbit around a cool red dwarf star by a suite of instruments, including the NEID radial-velocity instrument on the WIYN 3.5-meter Telescope at Kitt Peak National Observatory, a Program of NSF's NOIRLab. The planet, named TOI-3757 b, is the fluffiest gas giant planet ever discovered around this type of star.

Analysis of research on Myanmar amber fossils shows explicit links to political, legal and economic changes

Myanmar, a country in Southeast Asia, is plagued by political and economic crises. The fall of a president, a military putsch and the crackdown on religious minorities have had an impact not only on life but also on research in the country. One area of research that has been particularly affected is research into fossils preserved in amber.

Study reveals a broken symmetry in the roughness of elastic interfaces

A large class of problems in non-equilibrium statistical physics deal with driven dynamics of elastic interfaces in random media. Examples include stress-driven propagation of crack fronts in disordered solids, motion of domain walls driven by applied magnetic fields in disordered ferromagnets, and dynamics of fluid fronts invading a porous medium—for example, when coffee spilled on the table is absorbed by the tablecloth.
