MIT researchers have found that interactions between people from different economic backgrounds have dropped significantly since the start of the Covid-19 pandemic, reports David Scharfenberg for The Boston Globe. Scharfenberg notes the “the phenomenon could hurt low-income people in direct ways – they’ll lose connections to better-off people – and indirect ways.”
Researchers from MIT have found that Twitter “bot detection tools can rely on funky, flawed data sets that replicate mistakes made within one another, rather than trying to accurately identify bots,” reports Chris Stokel-Walker for Fast Company. “We realized that this was a systemic issue in the data sets that are commonly used for bot detection,” says postdoc Zachary Schutzman.
Prof. Marzyeh Ghassemi speaks with NPR host Emily Kwong and correspondent Geoff Brumfiel about how artificial intelligence could impact medicine. “When you take state-of-the-art machine-learning methods and systems and then evaluate them on different patient groups, they do not perform equally,” says Ghassemi.
MIT researchers have found that by “encouraging strategic EV charging placement, rather than allowing EV chargers to be situated merely due to charging company convenience or preferences” it may be possible to “mitigate or eliminate EV charging problems without the need for advanced technological systems of connected devices and real-time communications, which could add to costs and energy consumption,” reports Carolyn Fortuna for CleanTechnica.
MIT researchers have found that placing EV charging stations in strategic locations and setting up charging systems to initiate charging at delayed times could help reduce the impact of EVs on the electrical grid, reports Michael Schoeck for PV Magazine.
MIT scientists have found that delayed charging and strategic placement of EV charging stations could help reduce additional energy demands caused by more widespread EV adoption, reports Grace Carroll for Fast Company. “Leveraging these two strategies together significantly eliminates any additional energy demands,” writes Carroll, “and can be tailored to specific local conditions to help cities meet their decarbonization goals.”
A new study by MIT researchers finds that strategic placement of EV charging stations and creating systems to help stagger charging times could help reduce or eliminate the need for new power plants to handle the impact of EV charging on the grid, reports Sharon Udasin and Saul Elbein for The Hill. The researchers found that “better availability of charging stations at workplaces could help take advantage of peak power being produced midday by solar energy facilities.”
Associate Prof. Sarah Williams speaks with Erin Langer at Metropolis about the Civic Data Design Lab’s Motivational Tapestry, a large woven art piece that uses data from the United Nations World Food Program to visually represent the individual motivations of 1,624 Central Americans who have migrated to the U.S. “By allowing a dialogue to open up and be less defensive, art allows us to understand and conceptualize an issue from a different vantage point,” explains Williams.
Prof. Jessika Trancik speaks with Bloomberg reporter Kyle Stock about the carbon impact of electric vehicles. “On average, your emissions are substantially lower if you go for the full electric [vehicle],” says Trancik. “But we could probably think of extreme edge cases where a hybrid is just as good.”
The Verge reporter Justine Calma writes that a new study by MIT researchers finds that while wind energy has measurably improved air quality, only 32% of those benefits reached low-income communities. “The research shows that to squeeze out the greatest health benefits, wind farms need to intentionally replace coal and gas power plants,” writes Calma. “And to clean up the most polluted places — particularly those with more residents of color and low-income households — those communities need to be in focus when deploying new renewable energy projects.”
A new study by MIT researchers finds that increased usage of wind power is improving air quality in parts of the U.S., however only a third of the health benefits are being seen in disadvantaged communities, reports Alan Mozes for HealthDay. "Going forward," explains Prof. Noelle Selin, "more targeted policies are needed to reduce the disparities at the same time, for example by directly targeting [fossil fuel] sources that influence certain marginalized communities."
Increased usage of wind energy has led to health benefits, but does not affect all communities equally, reports Saul Elbein for The Hill. The researchers found that in order to increase the benefits of wind energy, “the electricity industry would have to spin down the most polluting plants at times of high wind-supply — rather than their most expensive ones,” writes Elbein.
Prof. Jessika Trancik speaks with Science Friday host Ira Flatow about the future of electric vehicles. “I think there is a lot happening in this space both coming from the private sector and then also from these government incentives coming in to accelerate that process,” says Trancik.
Prof. Jessika Trancik says that the tax incentive in the Inflation Reduction Act may help encourage the transition to electric vehicles due to the income cap for people to qualify, reports Lily Jamali for Marketplace. “I think it’s really important to structure them in such a way that the benefits are equitably distributed across the population,” says Trancik.
Loh Down on Science host Sandra Tsing Loh spotlights Prof. Cathy Wu and graduate student Vindula Jayawardana and their work developing a new method for self-driving vehicles that would help minimize idling at red lights. “In their method, self-driving can be taught to minimize stops at red lights. To make this work, traffic lights and self-driving cars would have sensors. This would let them check in with each other on their surroundings,” says Loh.
