Ekström’s work spans many facets of global earthquake seismology, from the nature of individual earthquakes and other seismic sources to the large-scale structure of the Earth.

Scientists have found evidence that Mercury’s inner core is indeed solid, and that it is nearly the same size as Earth’s inner core. The new findings offer clues about how the solar system formed and how rocky planets change over time.

Brian Greene, professor of physics and mathematics at Columbia, discusses the first-ever image of a black hole, which has the potential to redefine our understanding of the cosmos.

In a new study, scientists led by Jordan Abell, a graduate student at Columbia's Lamont-Doherty Earth Observatory, use urine salts to reconstruct the timing and scale of the Neolithic revolution at a Turkish archaeological site.

Columbia University scientists, in collaboration with researchers from Nimbus Therapeutics, have demystified a metabolic enzyme that could be the next major molecular target in cancer treatment.
