MIT researchers and two high school seniors have developed DualFair, a new technique for removing bias from a mortgage lending dataset, reports Hiawatha Bray for The Boston Globe. “When a mortgage-lending AI was trained using DualFair and tested on real-world mortgage data from seven US states,” writes Bray, “the system was less likely to reject applications of otherwise qualified borrowers because of their race, sex, or ethnicity.”
MIT startup ReadySet, co-founded by Alana Marzoev PhD ’18 and Jon Gjengset PhD ’20, provides database infrastructure to help developers build real-time applications, reports Kyle Wiggers for TechCrunch. “Rather than rebuilding these same broken systems, developers need solutions that slot into their existing infrastructure and achieve limitless read scaling,” says Marzoev. “With ReadySet, we aim to make the process of globally caching… query results as streamlined and automated as caching images in a content delivery system.”
Writing for The Los Angeles Times, Prof. Simon Johnson makes the case for imposing more stringent sanctions on Russia. “The war crimes committed by Russian forces at Bucha in Ukraine have brought greater clarity to economic sanctions,” writes Johnson. “What is in place now is insufficient and needs to be expanded.”
Prof. Jackson G. Lu co-authored a research article which suggests “East Asian students are also struggling in classrooms where assertiveness is expected but not necessarily encouraged within their cultures,” reports Katherine Mangan for The Chronicle of Higher Education.
Prof. Jessika Trancik speaks with Wall Street Journal reporter Nidhi Subbaraman about the dramatic drops in costs to manufacture and sell renewable technologies. Subbaraman notes that Trancik’s research shows that “the steep drop in solar and lithium-ion battery technology was enabled by market expansion policies as well as investment in research and development by governments and the private sector.”
MIT researchers have found five main predictors of attrition: toxic work culture, job insecurity, stressing innovation, not being recognized for performance, and poor response to Covid-19, reports Meghan M. Biro for Forbes. “Everything boils down to valuing your people – and possibly undertaking a bout of serious self-assessment,” writes Biro.
New research by Professor Erik Demaine, lecturer Zachary Abel, robotics engineer Martin Demaine and their colleagues explores whether it is possible to “take any polyhedral (or flat-sided) shape that’s finite (like a cube, rather than a sphere or the endless plane) and fold it flat using creases," writes Rachel Crowell for Quanta Magazine. “By moving finite to infinite ‘conceptual’ slices, they created a procedure that, taken to its mathematical extreme, produced the flattened object they were looking for,” Crowell explains.
The MIT AI Hardware Program seeks to bring together researchers from academia and industry to “examine each step of designing and manufacturing the hardware behind AI-powered technologies,” reports Emily Bamforth for EdScoop. “This program is about accelerating the development of new hardware to implement AI algorithms so we can do justice to the capabilities that computer scientists are developing,” explains Prof. Jesús del Alamo.
Using cellulose nanocrystals found in trees, MIT researchers have developed a new material that is both tough and strong, reports Kathryn Hulick for Science News for Students. Abhinav Rao PhD ’18 explains that he was inspired to create the material “by looking at what nature has to teach us.”
A study conducted by Prof. Susan Solomon and her colleagues has found that unlike CFCs, smoke destroys the ozone in a more roundabout way, creating concerns due to the impact of the Australian bushfires of 2019-2020, reports Krystal Vasquez for EOS. “Because of the sheer scale of the event [the Australian bushfires] massive amounts of smoke penetrated the normally pristine upper stratosphere,” writes Vasquez.
FTX CEO Sam Bankman-Fried ‘14 speaks with Bloomberg reporter Zeke Faux about his work in cryptocurrency and the influence of the effective-altruism movement in his philanthropic work. Bankman-Fried explains that he plans to “keep enough money to maintain a comfortable life," writes Faux. “Other than that, he still plans to give it all away – every dollar, or Bitcoin, as the case may be.”
Amazon workers from Staten Island have become the first group to vote in favor of unionizing, reports Ari Levy and Annie Palmer for CNBC. “I would expect now that there is this first victory on the part of a union that Amazon is going to have to reassess its labor relations strategy and begin to negotiate in good faith to reach an agreement,” says Prof. Tom Kochan.
MIT researchers have developed reconfigurable, self-assembling robotic cubes embedded with electromagnets that allow the robots to easily change shape, reports John Koetsier for Forbes. “If each of those cubes can pivot with respect to their neighbors you can actually reconfigure your first 3D structure into any other arbitrary 3D structure,” explains graduate student Martin Nisser.
To celebrate the list of known exoplanets topping 5,000, New York Times reporter Becky Ferreira spoke with astronomers, actors and astronauts about their favorite exoplanets or exoplanetary systems. “TOI-1233 is an outstanding planetary system with its high number of transiting planets, sunlike host star and its proximity to the solar system,” says postdoc Tansu Daylan of the system he detected along with two high school students he was mentoring.
Educators from the Asia School of Business and MIT have developed a course aimed at teaching central bankers how the market is impacted by bottlenecks and how monetary policy can help, reports Enda Curran for Bloomberg. “The curriculum covers topics that include crisis prevention, behavioral finance, cybersecurity, digital currencies, and ethics,” writes Curran.
