Fulfilling the ultimate goal of the 2015 Paris Agreement on climate change — keeping global warming well below 2 degrees Celsius, if not 1.5 C — will be impossible without dramatic action from the world’s largest emitter of greenhouse gases, China. Toward that end, China began in 2017 developing an emissions trading scheme (ETS), a […] More
Omer Tanovic, a PhD candidate in the Department of Electrical Engineering and Computer Science, joined the Laboratory for Information and Decision Systems (LIDS) because he loves studying theory and turning research questions into solvable math problems. But Omer says that his engineering background — before coming to MIT he received undergraduate and master’s degrees in […] More
In any conventional silicon-based solar cell, there is an absolute limit on overall efficiency, based partly on the fact that each photon of light can only knock loose a single electron, even if that photon carried twice the energy needed to do so. But now, researchers have demonstrated a method for getting high-energy photons striking […] More
Catherine Drennan says nothing in her job thrills her more than the process of discovery. But Drennan, a professor of biology and chemistry, is not referring to her landmark research on protein structures that could play a major role in reducing the world’s waste carbons. “Really the most exciting thing for me is watching my […] More
Greentown Labs is the largest clean technology incubator in North America, a fact that’s easy to accept when you walk inside. The massive, open entrance of Greentown’s Somerville, Massachusetts, headquarters gives visitors the impression they’ve entered the office of one of Greater Boston’s most successful tech companies. Beyond the modern entryway are smaller working spaces […] More
A broad class of materials called perovskites is considered one of the most promising avenues for developing new, more efficient solar cells. But the virtually limitless number of possible combinations of these materials’ constituent elements makes the search for promising new perovskites slow and painstaking. Now, a team of researchers at MIT and several other […] More
The cloud’s very name reflects how many people think of this data storage system: intangible, distant, and disentangled from day-to-day life. But MIT PhD student Steven Gonzalez is reframing the image and narrative of an immaterial cloud. In his research, he’s showing that the cloud is neither distant nor ephemeral: It’s a massive system, ubiquitous […] More
MIT researchers have developed a novel “photonic” chip that uses light instead of electricity — and consumes relatively little power in the process. The chip could be used to process massive neural networks millions of times more efficiently than today’s classical computers do. Neural networks are machine-learning models that are widely used for such tasks […] More
