Calls have been made to help scientists in Afghanistan after the country was plunged into chaos in August when the Taliban regime took power in the war-torn country. Universities and other educational institutions have already closed their doors and science education has ground to a halt. Some scientists have even fled abroad, believing themselves direct targets of the Taliban.

Physics World: Bose-Einstein condensates hit record low temperature
A new way of controlling the expansion of matter in a freely-falling Bose-Einstein condensate (BEC)has produced the coldest effective temperature ever measured: 38 pK (10 K) above absolute zero. The method, which allowed researchers in Germany and France to image the condensate’s evolution for more than two seconds, opens the door to enhanced measurements of the gravitational constant g and photon recoil, and could even offer an alternative mea
