MIT researchers have found that online restaurant data can be used to accurately predict key socioeconomic factors for neighborhoods in China, reports the Xinhua news agency. The researchers found that “in nine Chinese cities, the presence of restaurants could effectively predict a neighborhood's daytime and nighttime population, the number of businesses and overall spending.”
WBUR’s Pamela Reynolds spotlights the new Becca Albee installation at the MIT List Visual Arts Center. “It's thinking about singular, intimate moments, somebody reflecting on a friendship or a relationship that was in the near past and then stepping back and thinking about time on a geologic scale,” says Yuri Stone, who curated the exhibit.
A new instrument device developed by MIT researchers improves the detection of gravitational waves by squeezing the vacuum of spacetime, reports Ryan Mandelbaum for Gizmodo. “The method enables us to increase the distance in the universe at which we can detect gravitational waves,” explains principal research scientist Lisa Barsotti.
Boston Globe reporter Martin Finucane writes that MIT researchers have built a new instrument that has increased the number of gravitational waves LIGO can detect. “With an accompanying increase in the power of the lasers used, the detectors have extended their range to more than 400 million light years, allowing it to detect about one wave a week,” Finucane explains.
