New research shows that shifting Antarctic circulation after the last Ice Age released ancient deep-ocean carbon into the atmosphere. Using Southern Ocean sediment cores, scientists traced how expanding Antarctic Bottom Water mixed long-isolated, carbon-rich waters upward. The findings reveal a major but underappreciated driver of early Holocene warming.

A new study by NIST physicists shows that clocks on Mars run about 477 microseconds faster per day than identical clocks on Earth. The difference comes from Mars’s weaker gravity, orbital eccentricity, and gravitational influences across the solar system. Though tiny, this daily time lead will pose challenges for future Mars navigation and communication networks, re…
