Writing for Bloomberg, Prof. Carlo Ratti and Arianna Salazar-Miranda SM '16, PhD '23 explore the possibility and potential of developing 15-minute cities in America. “If implemented correctly, the 15-minute city can be an agent of freedom: freedom from traffic jams, freedom to live in a healthy environment and freedom to be outside,” they write. “It is not a one-size-fits-all solution, but our research shows that almost every community in America could benefit from a few more well-placed amenities.”

Researchers from MIT have developed liquid metal printing, a new technique that can be used to quickly 3D print large-scale objects such as furniture, reports Designboom. The researchers say this technique can enable 3D printing, “ten times faster than a comparable metal additive manufacturing process, and the process of melting the metal may be more efficient than some other methods, given that metal is also more accessible with the abundance of scraps that can be recycled,” writes Designboom.

MIT researchers have developed a 3D printing technique called liquid metal printing (LMP) that capable of printing large aluminum parts at least 10 times faster than a comparable metal additive manufacturing process, reports Brian Heater for TechCrunch. LMP “utilizes a bed of 100-micron glass beads to create a structure into which molten aluminum is deposited — a process not entirely dissimilar from injection molding,” explains Heater. “The beads are capable of standing up to the intense temperature, while allowing the heat to quickly dissipate as the metal solidifies.”

Writing for Financial Times, Prof. Carlo Ratti examines recent attempts to shorten journeys between major cities, such as a hyperloop system that would transport passengers via giant vacuum tubes from London to Paris in about 20 minutes. “Customers clearly prefer a smooth experience to maximum speed,” writes Ratti. “They might also be choosing the Eurostar for having a carbon footprint that is about 95 per cent less than that of aircraft. While the hyperloop might have emitted less per journey than a plane, and perhaps even a high-speed train, its construction would have had a huge environmental cost.”

Popular Mechanics reporter Jill Waldbieser spotlights Prof. Hugh Herr and his work developing prosthetic limbs that integrate with their human hosts using a surgical technique that preserves the sensation in artificial limbs. “In the future, on the order of five years or so, we’ll be so good at this, we’ll completely restore the signals from the prosthetic to the brain and from the brain to the prosthetic, like the limb was never amputated,” says Herr.

Lecturer James Aloisi and several students from his urban planning and policy course write for Commonwealth Beacon about their proposals for creating a better public transportation connection between Kendall Square and Logan Airport. “It should not be acceptable that, in greater Boston in the 21st Century, a traveler cannot easily and conveniently connect by transit from one of the nation’s most important innovation and academic centers to the international airport, a mere three miles away,” writes Aloisi. “We can do better, and we must do better if we want to do more than just pretend that we live in a livable, sustainable region.”

David Zipper, a senior fellow at the MIT Mobility Initiative, speaks with Kai Ryssdal of Marketplace about how cars in the U.S. are getting heavier and larger, and the environmental and safety costs associated with larger vehicles. “For decades, people who buy enormous, very heavy cars have been creating societal costs that they aren’t paying for. That’s what’s called a market failure,” said Zipper. “So if you want the market for automobiles to succeed, we need to make sure that when people are shopping for their next car, they are considering the societal costs of their purchase.”

Prof. Canan Dagdeviren and her team have developed a wearable ultrasound patch that can be used to screen for breast cancer at home, reports Grace Browne for Wired. “Dagdeviren wants to give people the opportunity to know what’s happening inside their bodies every day, the same way we check the weather forecast,” writes Browne.

Writing for The New York Times, Prof. Carlo Ratti and Harvard Prof. Edward L. Glaeser make the case that “the Bay Area needs a lot more housing, and we may need privately built cities to get there.” Ratti and Glaeser note, “building in the Bay Area will enable America to continue its history of allowing people to relocate to more productive places.”

La Biennale di Venezia’s Board of Directors has named Prof. Carlo Ratti as the curator for the 19^th International Architecture Exhibition, reports DesignBoom. “Recognized as one of the leading scholars in urban planning, Ratti has co-authored more than 750 publications,” notes DesignBoom, adding that his, “involvement in curatorial projects spans various countries and prestigious platforms.”

Prof. Carlo Ratti has been named curator of the 2025 International Architecture Exhibition, the Biennale Architettura, reports Maria-Cristina Florian for ArchDaily. “We architects like to think we are smart, but real intelligence is everywhere,” says Ratti. “The disembodied ingenuity of evolution, the growing power of computers, and the collective wisdom of the crowd. To face a burning world, architecture must harness all the intelligence around us. I am honored and humbled to have the opportunity to curate the Biennale Architettura 2025.” 

Researchers from MIT have developed, “nanoelectronics they hope can one day enter the brain and treat conditions like Alzheimer’s by monitoring some of these brain patterns,” reports Elizabeth Hlavinka for Salon. “Their device, which they call Cell Rover, serves as a sort of antenna that can help external devices monitor cells.”

Joy Buolamwini PhD '22 joins Tonya Mosley on NPR’s Fresh Air podcast to discuss her new book, Unmasking AI: My Mission to Protect What Is Human in a World of Machines. "With the adoption of AI systems, at first I thought we were looking at a mirror, but now I believe we're looking into a kaleidoscope of distortion," Buolamwini says. "Because the technologies we believe to be bringing us into the future are actually taking us back from the progress already made."

Four faculty members from across MIT - Professors Song Han, Simon Johnson, Yoon Kim and Rosalind Picard - speak with Curiosity Stream about the opportunities and risks posed by the rapid advancements in the field of AI. “We do want to think about which human capabilities we treasure,” says Picard. She adds that during the Covid-19 pandemic, “we saw a lot of loss of people's ability to communicate with one another face-to-face when their world moved online. I think we need to be thoughtful and intentional about what we're building with the technology and whether it's diminishing who we are or enhancing it.”

New York Times reporter Conor Dougherty spotlights DUSP graduate student Nick Allen MS '17 and his work advocating for Land-value taxes (LVT) in distressed US cities.
