Antarctica's record ice gain traced to tropical ocean warming

New Capabilities

Led the study identifying the tropical warm pool mechanism

Between July 2021 and April 2023, East Antarctica gained roughly 695 billion tons of ice, the largest 22-month mass gain in two decades. The gain briefly paused a decline that had been losing about 140 billion tons per year since 2003.

Star formation across the universe drops sharply while hydrogen fuel holds steady

New Capabilities

Led the international research team

The universe makes stars about 60% less often than it did 4.5 billion years ago. A new survey of 2.5 million galaxies shows the simple explanation, that galaxies ran out of star-making fuel, doesn't hold.

Chinese researchers build first sodium-ion battery that survives extreme heat without catching fire

New Capabilities

Publisher of the Nature Energy study via its Institute of Physics

Every rechargeable battery in every electric car carries this vulnerability: if something goes wrong — a puncture, defect, or short circuit — temperatures spike and trigger thermal runaway, a self-feeding chain reaction producing toxic smoke, fire, and sometimes explosions. A team at the Chinese Academy of Sciences published in Nature Energy results on a sodium-ion battery with an electrolyte that automatically solidifies into a physical barrier when heat exceeds 150 degrees Celsius, cutting off thermal runaway before it starts. The battery survived nail-puncture and 300-degree-Celsius oven tests without smoke, fire, or explosion, a first for large-format sodium-ion cells.
