Nicolás Young studies glaciers and ice sheets, and how they’ve changed in the past. His work earned him the Blavatnik Award for Young Scientists last fall, which came with a $30,000 prize. You can hear him talk about his research in this new video, produced by the Blavatnik Family Foundation.

Sidney Hemming is preparing to spend two months at sea studying global ocean circulation and southern Africa's climate variability over the past 5 million years.

That change would have affected the monsoons, today relied on to feed over half the world’s population, and could have helped tip the climate system over the threshold for deglaciation.

Being aboard a ship is isolating—but for a scientist, it’s not lonely.

Much of the eastern two-thirds of the United States was balmy on Christmas Day, with high temperatures more than 20°F above average from Texas to Maine. According to NOAA, 789 daily high temperature records were tied or broken on Christmas Eve and Christmas Day in the continental United States. What’s behind this unusual weather?

The bottom of the ocean just keeps getting better. Or at least more interesting to look at.

We’ve just completed our first full station and are remarkably pleased with the results. We collected 8 seawater samples to measure helium isotopes; 20 to measure thorium and protactinium isotopes; 7 in-situ pump filters; 1 box core of the ocean floor; and more.

With an abundance of time and a dearth of work, we have begun to devise ways of doing science before we can actually do science at sea. Among other things, we set up an imaging system to take pictures of particle filters we bring back from the deep sea.

In the weeks before departing for my first scientific cruise, everyone I knew who had ever been to sea gave me some form of the same advice: Nothing ever works the way you expect it to work at sea.

Over the last six years, seismologists Göran Ekström and Colin Stark have been perfecting a technique for picking out the seismic signature of large landslides. They just discovered North America’s largest known landslide in many years – 200 million tons of sliding rock in Alaska.

Elise Rumpf's lava flow simulations are yielding new details about the velocity of lava over different surfaces. They may also hold clues about the surfaces of other planets.
