    Seeding oceans with iron may not impact climate change

    Historically, the oceans have done much of the planet’s heavy lifting when it comes to sequestering carbon dioxide from the atmosphere. Microscopic organisms known collectively as phytoplankton, which grow throughout the sunlit surface oceans and absorb carbon dioxide through photosynthesis, are a key player. To help stem escalating carbon dioxide emissions produced by the burning […] More

    Half of U.S. deaths related to air pollution are linked to out-of-state emissions

    More than half of all air-quality-related early deaths in the United States are a result of emissions originating outside of the state in which those deaths occur, MIT researchers report today in the journal Nature. The study focuses on the years between 2005 and 2018 and tracks combustion emissions of various polluting compounds from various […] More

    Brainstorming energy-saving hacks on Satori, MIT’s new supercomputer

    Mohammad Haft-Javaherian planned to spend an hour at the Green AI Hackathon — just long enough to get acquainted with MIT’s new supercomputer, Satori. Three days later, he walked away with $1,000 for his winning strategy to shrink the carbon footprint of artificial intelligence models trained to detect heart disease.  “I never thought about the kilowatt-hours I was […] More

    Testing the waters

    In 2010, the U.S. Army Corps of Engineers began restoring the Broad Meadows salt marsh in Quincy, Massachusetts. The marsh, which had grown over with invasive reeds and needed to be dredged, abutted the Broad Meadows Middle School, and its three-year transformation fascinated one inquisitive student. “I was always super curious about what sorts of […] More

    How long will a volcanic island live?

    When a hot plume of rock rises through the Earth’s mantle to puncture the overlying crust, it can create not only a volcanic ocean island, but also a swell in the ocean floor hundreds to thousands of kilometers long. Over time the island is carried away by the underlying tectonic plate, and the plume pops […] More

    Screen could offer better safety tests for new chemicals

    It’s estimated that there are approximately 80,000 industrial chemicals currently in use, in products such as clothing, cleaning solutions, carpets, and furniture. For the vast majority of these chemicals, scientists have little or no information about their potential to cause cancer. The detection of DNA damage in cells can predict whether cancer will develop, but […] More

    Making buildings from industrial waste

    Elsa Olivetti’s interest in materials science began when she was an engineering science major at the University of Virginia. Initially unable to settle on any one form of engineering, she took an introduction to materials science class on a whim. She loved the way materials science let her examine everyday material, like a block of […] More
