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
To meet the long-term goals of the Paris Agreement on climate change — keeping global warming well below 2 degrees Celsius and ideally capping it at 1.5 C — humanity will ultimately need to achieve net-zero emissions of greenhouse gases (GHGs) into the atmosphere. To date, emissions reduction efforts have largely focused on decarbonizing the […] More
The generation of electricity is a huge contributor to the world’s emissions of climate-altering greenhouse gases, producing some 25 percent globally. That’s because more than two-thirds of the world’s electricity is still being produced by burning fossil fuels. But progress in a variety of areas could allow for drastic reductions in those emissions, as several […] More
MIT Dining, in collaboration with the MIT Office of Sustainability, has been selected as one of six recipients of the 2019 Henry P. Kendall Foundation New England Food Vision Prize. Launched by the Henry P. Kendall Foundation in 2018, the New England Food Vision Prize Program gives out as many as six awards of up […] More
Resting atop Thomas Peacock’s desk is an ordinary-looking brown rock. Roughly the size of a potato, it has been at the center of decades of debate. Known as a polymetallic nodule, it spent 10 million years sitting on the deep seabed, 15,000 feet below sea level. The nodule contains nickel, cobalt, copper, and manganese — […] More
Nestled within sediments that accumulate in marine environments, fossil molecules sneakily record how climates and environments change over time. These fossils, vestiges of microbial membranes, preserve different chemical structures that reflect the changing world around them at the time the organisms lived. For almost two decades, scientists have used one class of these molecular fossils, […] More
About 2.4 billion years ago, at the end of the Archean Eon, a planet-wide increase in oxygen levels called the Great Oxidation Event (GOE) created the familiar atmosphere we all breathe today. Researchers focused on life’s origins widely agree that this transition event was caused by the global proliferation of photosynthetic microbes capable of splitting […] More
Providing seeds with a protective coating that also supplies essential nutrients to the germinating plant could make it possible to grow crops in otherwise unproductive soils, according to new research at MIT. A team of engineers has coated seeds with silk that has been treated with a kind of bacteria that naturally produce a nitrogen […] More
