There’s a line that stretches down North America, singeing into the continent a border that separates an arid west from a humid east. And research led by Columbia climate scientist Richard Seager found that it’s on the move.

Research by Stephen Goff, who studies viruses that cause leukemia in mice, revealed how a strange piece of mobile DNA has spread itself throughout the oceans, claiming real estate in the genomes of clams, fish, and more.

Ruth Angus, an astronomer at Columbia University, explains a new NASA mission, the Transiting Exoplanet Survey Satellite, and how it will spend two years scanning almost the entire sky to search for alien worlds.

The likelihood of Atlantic circulation stopping altogether is very low, and any drastic effects would take centuries to manifest, says Richard Seager, a climate scientist at Lamont-Doherty Earth Observatory.

Jupiter, which offers tools to help customers manage the risks of climate change, is funding several projects at Columbia’s Lamont-Doherty Earth Observatory, whose research evaluates many of these same risks.

Climate change: it's disrupting our planet, and it's going to disrupt your future travel plans, especially if you're planning to fly, says Columbia climate scientist Ethan Coffel.

A new paper by a group of researchers at Columbia University details a method for making tiny changes to fonts that the human eye can’t detect but that look entirely different to a computer vision algorithm.
