PNAS

A PNAS study by University of Toronto and University of Ottawa researchers provides the first direct, decade-long measurements of white hydrogen discharging from an Ontario mine, extrapolating to 140+ tonnes per year at a single site.

A PNAS paper from Harvard's Mahadevan lab shows that adding tuned noise to robot movement prevents gridlock in dense swarms, with physical validation at Eindhoven University of Technology.

A 30-year satellite study shows Antarctica lost 12,820 square kilometers of grounded ice, concentrated in West Antarctica's most vulnerable glaciers.
