(Top panel) Fit to Doppler parameter distribution and Lyman-alpha forest column density distribution function at z=0.1 assuming a maximum contribution of dark photon heating to linewidths. The contours show the projection of the 68% and 95% intervals for the mass and the mixing parameter of the dark photon. Colors correspond to different assumptions about the …
An illustration of a boron arsenide crystal placed between two diamonds in a controlled chamber with thermal energy carried under extreme pressure. Credit: The H-Lab/UCLA UCLA researchers and their colleagues have discovered a new physical principle governing how heat is transferred through materials, and the discovery contradicts the conventional wisdom that heat always moves faster …

More than 20,000 people have died across western Europe in this summer’s heatwaves, at temperatures that would have been virtually impossible without the deteriorating climate, figures show. Analysis of excess deaths, the difference between the number of deaths that have occurred and those expected based on historical trends, reveals the threats posed by climate change-induced …
