Citizens emerge from the slums

Do the world’s nearly 1 billion urban poor, who subsist without legal housing, reliable water and sewer infrastructure, and predictable employment, lack political engagement as well? Ying Gao does not buy the claim by many social scientists that social and economic marginalization necessarily means political marginalization. “My results contradict the prevailing wisdom about slums and […]

Study: Global cancer risk from burning organic matter comes from unregulated chemicals

Whenever organic matter is burned, such as in a wildfire, a power plant, a car’s exhaust, or in daily cooking, the combustion releases polycyclic aromatic hydrocarbons (PAHs) — a class of pollutants that is known to cause lung cancer. There are more than 100 known types of PAH compounds emitted daily into the atmosphere. Regulators, […]

Data flow’s decisive role on the global stage

In 2016, Meicen Sun came to a profound realization: “The control of digital information will lie at the heart of all the big questions and big contentions in politics.” A graduate student in her final year of study who is specializing in international security and the political economy of technology, Sun vividly recalls the emergence […]

Researchers design sensors to rapidly detect plant hormones

Researchers from the Disruptive and Sustainable Technologies for Agricultural Precision (DiSTAP) interdisciplinary research group of the Singapore-MIT Alliance for Research and Technology (SMART), MIT’s research enterprise in Singapore, and their local collaborators from Temasek Life Sciences Laboratory (TLL) and Nanyang Technological University (NTU), have developed the first-ever nanosensor to enable rapid testing of synthetic auxin […]

Smarter regulation of global shipping emissions could improve air quality and health outcomes

Emissions from shipping activities around the world account for nearly 3 percent of total human-caused greenhouse gas emissions, and could increase by up to 50 percent by 2050, making them an important and often overlooked target for global climate mitigation. At the same time, shipping-related emissions of additional pollutants, particularly nitrogen and sulfur oxides, pose […]

New device can diagnose Covid-19 from saliva samples

Engineers at MIT and Harvard University have designed a small tabletop device that can detect SARS-CoV-2 from a saliva sample in about an hour. In a new study, they showed that the diagnostic is just as accurate as the PCR tests now used. The device can also be used to detect specific viral mutations linked […]

Using graphene foam to filter toxins from drinking water

Some kinds of water pollution, such as algal blooms and plastics that foul rivers, lakes, and marine environments, lie in plain sight. But other contaminants are not so readily apparent, which makes their impact potentially more dangerous. Among these invisible substances is uranium. Leaching into water resources from mining operations, nuclear waste sites, or from […]

How authoritarian leaders maintain support

How do authoritarian regimes sustain their popularity? A novel study in China led by MIT scholars shows that anticorruption punishments meted out by government authorities receive significant support among citizens — who believe such actions demonstrate both competence and morally righteous leadership. The findings help explain how authoritarian governments endure, not merely based on domination […]

Vapor-collection technology saves water while clearing the air

About two-fifths of all the water that gets withdrawn from lakes, rivers, and wells in the U.S. is used not for agriculture, drinking, or sanitation, but to cool the power plants that provide electricity from fossil fuels or nuclear power. Over 65 percent of these plants use evaporative cooling, leading to huge white plumes that […]

A sleep study’s eye-opening findings

Subjectively, getting more sleep seems to provide big benefits: Many people find it gives them increased energy, emotional control, and an improved sense of well-being. But a new study co-authored by MIT economists complicates this picture, suggesting that more sleep, by itself, isn’t necessarily sufficient to bring about those kinds of appealing improvements. The study […]
