Prof. Giovanni Traverso and colleagues have developed a new ingestible sensor that could be used to help diagnose gastrointestinal conditions, reports Jeremy Hsu for New Scientist. “Eventually, the futuristic device could provide treatments for gut illnesses through electrical stimulation via additional electrodes embedded in the sensor,” Hsu notes.  

Writing for STAT, Prof. Kevin Esvelt explores how, “the immense potential benefits of biotechnology are profoundly vulnerable to misuse. A pandemic caused by a virus made from synthetic DNA — or even a lesser instance of synthetic bioterrorism — would not only generate a public health crisis but also trigger crippling restrictions on research.” Esvelt adds: “The world has too much to gain from the life sciences to continue letting just anyone obtain DNA sufficient to cause a pandemic.” 

Professor Jacopo Buongiorno talks with Steve Curwood of Living on Earth about new investments in nuclear power generation, advanced reactors and waste disposal. He notes roughly half the clean energy in the U.S. comes from nuclear, with great potential due to its adaptability. “The nice thing about nuclear is that it’s a fairly versatile energy source,” explains Buongiorno. “It can give you heat, if you want heat. It can give you electricity if you want electricity. It can give you hydrogen if you need hydrogen, or some kind of synthetic fuel for transportation." 

Prof. John Sterman speaks with New York Times reporter Susan Shain about the effectiveness of flight offsets. Sterman explains that few offset project results are verifiable, immediate and durable, part of his criteria for legitimacy. Better recommendations include insulating your home or buying an electric car.

Boston Globe reporter Mark Feeney spotlights “Drawing After Modernism,” a new exhibit at the MIT Museum that showcases various architectural sketches in different mediums. “There are some 50 items on display, not just artworks but also colored pencils, an airbrush, and exhibition cards for a 1977 exhibition at New York’s Leo Castelli gallery,” explains Feeney. “The MIT show is pretty much an ideal size: small enough for a visitor to comfortably take everything in, big enough to be varied and wide-ranging.” 

Prof. Carlo Ratti and the WeBuildGroup have developed a proposal to help rebuild the Francis Scott Key Bridge in Baltimore, Maryland, reports Anna Cooban for CNN. Ratti explained that the blueprint was designed to “produce a safer bridge by widening the channels through which ships can pass, among other measures.” The design will help prevent “the risk of a tragedy such as the one of March 26 happening again,” Ratti explains. 

Prof. Yoon Kim speaks with USA Today reporter Eve Chen about how AI can be used in everyday tasks such as travel planning. “AI is generally everywhere,” says Kim. “For example, when you search for something – let’s say you search for something on TripAdvisor, Hotels.com – there is likely an AI-based system that gives you a list of matches based on your query.” 

Researchers from MIT and elsewhere have used an AI model to develop a “new approach to finding money laundering on Bitcoin’s blockchain,” reports Andy Greenberg for Wired. “Rather than try to identify cryptocurrency wallets or clusters of addresses associated with criminal entities such as dark-web black markets, thieves, or scammers, the researchers collected patterns of bitcoin transactions that led from one of those known bad actors to a cryptocurrency exchange where dirty crypto might be cashed out,” explains Greenberg. 

Writing for Project Syndicate, Institute Prof. Daron Acemoglu and Prof. Simon Johnson draw upon the work of economist David Ricardo and his insights on the Industrial Revolution to explore how to respond to the challenge posed by AI to good jobs. “It is still possible to have pro-worker AI, but only if we can change the direction of innovation in the tech industry and introduce new regulations and institutions,” they write.  

Prof. Earl K. Miller speaks with CBS News host Susan Spencer about  multitasking, fear of laziness, and the importance of downtime. “A lot of times some of your best thoughts come to you when your conscious mind is out of the way, when you allow the unconscious thoughts to bubble up,” says Miller. “And sometimes it’s good to be lazy – not lazy, but to tune out a bit and let these thoughts bubble up.”
