Pandemic is pushing women in STEM ‘past the point of no return’

Cryocoolers are ultracold refrigeration units used in surgery and drug development, semiconductor fabrication, and spacecraft. The regenerative heat exchanger, or regenerator, is a core component of cryocoolers. At temperatures below 10 kelvins, performance drops precipitously, with maximum regenerator loss of more than 50%. In Applied Physics Letters, researchers used superactivated carbon particles as an alternative regenerator material to increase cooling capability at temperatures as low as 4 kelvins.

Marine Fisheries Will Not Offset Farm Losses after Nuclear War

After a nuclear war, wild-catch marine fisheries will not offset the loss of food grown on land, especially if widespread overfishing continues, according to a Rutgers co-authored study. But effective pre-war fisheries management would greatly boost the oceans’ potential contribution of protein and nutrients during a global food emergency, according to the study in the journal Proceedings of the National Academy of Sciences. The study for the first time explored the effects of nuclear war on wild-catch marine fisheries.
