Researchers at MIT and the Beth Israel Deaconess Medical Center are combining machine learning and human-computer interaction to create a better electronic health record (EHR). They developed MedKnowts, a system that unifies the processes of looking up medical records and documenting patient information into a single, interactive interface.

Engineers at MIT have developed a new approach to removing lead or other heavy-metal contaminants from water, in a process that they say is far more energy-efficient than any other currently used system, though there are others under development that come close. Ultimately, it might be used to treat lead-contaminated water supplies at the home level, or to treat contaminated water from some chemical or industrial processes.

Would you like to live longer? It turns out that where you live, not just how you live, can make a big difference. That’s the finding of an innovative study co-authored by an MIT economist, which examines senior citizens across the U.S. and concludes that some locations enhance longevity more than others, potentially for multiple reasons.

Electrochemical reactions that are accelerated using catalysts lie at the heart of many processes for making and using fuels, chemicals, and materials — including storing electricity from renewable energy sources in chemical bonds, an important capability for decarbonizing transportation fuels. Now, research at MIT could open the door to ways of making certain catalysts more active, and thus enhancing the efficiency of such processes.

In the face of grave concerns about misinformation, social media networks and news organizations often employ fact-checkers to sort the real from the false. But fact-checkers can only assess a small portion of the stories floating around online. A new study by MIT researchers suggests an alternate approach: Crowdsourced accuracy judgements from groups of normal readers can be virtually as effective as the work of professional fact-checkers.

Two MIT professors have proposed a new approach to estimating the risks of exposure to Covid-19 under different indoor settings based on the number of people, the size of the space, the kinds of activity, whether masks are worn, and the ventilation and filtration rates.

MIT Associate Professor Andrews Sevtsuk has developed a model of pedestrian movement that could help planners and developers better grasp the flow of foot traffic in all cities. His work emphasizes the functionality of a neighborhood's elements, above and beyond its physical form, making the model one that could be used from Cambridge to Cape Town.

Thousands of different bacterial species live within the human gut. Most are beneficial, while others can be harmful. A new study from an MIT-led team has revealed that these bacterial populations can remake themselves within the lifetime of their host, by passing genes back and forth. They also found for people in industrialized societies this happens at much higher rates.

Stopping the spread of political misinformation on social media may seem like an impossible task. But a new study co-authored by MIT scholars finds that most people who share false news stories online do so unintentionally, and that their sharing habits can be modified through reminders about accuracy.

The world’s oceans are a vast repository for gases including ozone-depleting chlorofluorocarbons, or CFCs. They absorb these gases from the atmosphere and draw them down to the deep, where they can remain sequestered for centuries and more.

Marine CFCs have long been used as tracers to study ocean currents, but their impact on atmospheric concentrations was assumed to be negligible. Now, MIT researchers have found the oceanic fluxes of at least one type of CFC, known as CFC-11, do in fact affect atmospheric concentrations.
