Researchers from the Hebrew University of Jerusalem have discovered that a surface can withstand all local geometric conditions—and yet reach a global threshold beyond which it cannot remain smooth. The result may help understand shapes in nature

A new theoretical study points to another problem with interstellar light sails: As they approach relativistic speeds, the Doppler effect and the deflection of light reduce the efficiency of the thrust. In one of the weakest contributions of light, even

A study in Physical Review Letters presents a combinatorial design method for metamaterials: controlling motion states and “frustrated” loops, graded response to pressure, and even matrix-vector multiplication using only mechanical displacements.
