“I’ll never forget the moment when I first saw new Cassini data come down from Titan’s surface,” says Samuel Birch. “I was in awe at witnessing this brand new, never-seen-before bit of our solar system.” Birch explores and models the evolution of the surfaces of planets, moons, and small bodies in the outer solar system, […] More
As the largest ecosystem on the planet, the ocean provides incredible resources and benefits to humanity — including contributing 2.5 percent of global GDP and 1.5 percent of global employment, as well as regulating our climate, providing clean energy, and producing much of the oxygen we breathe. But exploitation and human pressures — like pollution, […] More
There’s a lot the average person doesn’t know about concrete. For example, it’s porous; it’s the world’s most-used material after water; and, perhaps most fundamentally, it’s not cement. Though many use cement and concrete interchangeably, they actually refer to two different — but related — materials: Concrete is a composite made from several materials, one […] More
If you’ve ever turned down a city street only to be blasted with air, you’ve stepped into what is known as an urban canyon. Much like their geological counterparts, urban canyons are gaps between two tall surfaces — in this case, buildings. The gusts they channel, however, have real implications. They can magnify a hurricane’s […] More
When deciding on a major, one thing was clear for Michelle Kornberg — she didn’t want to be stuck inside for four years. “I like the environment of working on something in the lab, but I grew up in a very outdoorsy family,” she says. “I definitely knew I didn’t want to be inside all […] More
Imagine a massive mug of cold, dense cream with hot coffee poured on top. Now place it on a rotating table. Over time, the fluids will slowly mix into each other, and heat from the coffee will eventually reach the bottom of the mug. But as most of us impatient coffee drinkers know, stirring the […] More
In 2016, scientists at MIT and elsewhere observed the first signs of healing in the Antarctic ozone layer. This environmental milestone was the result of decades of concerted effort by nearly every country in the world, which collectively signed on to the Montreal Protocol. These countries pledged to protect the ozone layer by phasing out […] More
Over millions of years, Hawaiian volcanoes have formed a chain of volcanic islands stretching across the Northern Pacific, where ocean waves from every direction, stirred up by distant storms or carried in on tradewinds, have battered and shaped the islands’ coastlines to varying degrees. Now researchers at MIT and elsewhere have found that, in Hawaii, […] More
