Confirmation of tetrataenite in lunar soil returned from the South Pole–Aitken Basin sheds light on how space weathering shapes strong magnetic minerals on the Moon, offering fresh insights into the farside magnetic anomalies.

New research published in Science shows spaceborne satellite altimetry can detect two-dimensional tsunami wave patterns near the earthquake’s source, offering critical insight for coastal risk evaluation and preparedness planning. The study highlights three key implications for hazard science: dispersive modeling is remarkably useful for characterizing tsunamis near their source; satellite altimetry can add unique constraints when it observes tsunamis close to where they begin; and wide-swath altimetry provides a transformative tool for understanding earthquake rupture and improving tsunami hazard assessments.

Waterloo scientists have developed a new way to understand how the universe began, and it could change what we know about the Big Bang and the earliest moments of cosmic history. Their work suggests that the universe’s rapid early expansion could have arisen naturally from a deeper, more complete theory of quantum gravity.
