It’s an “extraordinary” find that “defies easy explanation” said co-author Alex Teachey — nothing like it exists in our own solar system. He and his colleague David Kipping are careful to call their discovery a “candidate moon,” noting that more studies are required to confirm its existence.

Columbia University researchers Denise B. Kandel and Eric R. Kandel have identified a molecular mechanism underlying nicotine’s gateway effect, finding it enhances and prolongs the pleasure we get from other activities.

John Mutter, a disaster researcher at Columbia University who studied the death toll of Hurricane Katrina, said, “We need to rethink what we mean by disaster-related mortality and not just look at the week immediately following the event for related deaths.”

One of the biggest repositories of the Earth’s memories is at Columbia University’s Lamont-Doherty Earth Observatory. There, scientists have been collecting cores for decades.

In the middle of the Arabian Sea, algae blooms are taking over the base of the food chain which could prove catastrophic for 120 million people living on the sea’s edge. Joaquim Goes, an ocean scientist at Lamont-Doherty Earth Observatory, discusses this growing problem.

Adam Sobel, a climate scientist at Columbia University, agrees that climate change is contributing to these storms. “We know there’s climate change, so we expect to see certain changes in hurricanes,” he says. “And we are starting to see hints of those happening already.”

Columbia is ramping up research on removing excess carbon dioxide from the atmosphere. “If you’re not tackling carbon, you’re not actually tackling the problem,” said Julio Friedmann, of the university's Center for Global Energy Policy.
