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.”

Prof. Jessika Trancik speaks with Bloomberg reporter Kyle Stock about the importance of scrappage programs, especially those that incentivize electrifying the current fleet of vehicles in the United States. “At any given point in time, you care about the composition of the fleet,” says Trancik. “Funding programs that would help turn over the fleet more rapidly makes a lot of sense.”

Principal Research Scientist Emre Gençer speaks with The Independent reporter Louise Boyle about natural hydrogen and its potential as a future renewable energy source. “There is a ‘mismatch’ where natural hydrogen is being discovered and where it could be used, which would require massive investments in completely new infrastructure,” says Gençer. “I think it will be part of the solution but we need to take it with a grain of salt.”

MIT researchers have developed a supercapacitor comprised of concrete and charcoal, that can store electricity and discharge as needed, reports Aleks Phillips for Newsweek. Researchers hope the device can provide “a cheap and architectural way of saving renewable energy from going to waste,” writes Phillips.

Jasmina Aganovic '09 speaks with MSNBC reporter Daniela Pierre-Bravo about her mission to transform the beauty industry by creating more sustainable products through her startup Arcaea. “The way that I’ve always viewed this industry is that it touches almost every single human being on this planet every single day,” says Aganovic. The beauty industry also, “plays such an important emotional role in our day-to-day lives in terms of self-expression and self-care, the ability to escape when things are a little bit tough, those like little small indulgences.”

Postdoctoral associate Milan Klöwer shares how large conferences can impact air travel and personal carbon footprints, reports Sydney Johnson for KQED. “Flying is one of the sectors where there are enormous inequalities,” says Klöwer. “The people that earn the most [money] fly the most, and therefore have personal carbon footprints that are thousands of times larger than the poorest people on the planet. There is a responsibility for people to understand that problem about how they are personally emitting.”

Prof. Kerry Emanuel speaks with Living on Earth host Jenni Doering about the future of extreme weather forecasting. “We have to do a much better job projecting long term risk, and how that's changing as the climate changes so that people can make intelligent decisions about where they're going to live, what they're going to build, and so on,” says Emanuel. “We need better models, we need better computers, so that we can resolve the atmosphere better, we need to make better measurements of the ocean below the surface, that's really tough to do.”

A number of MIT spinouts and research projects – including the MOXIE instrument that successfully generated oxygen on Mars, a new solar-powered desalination system and MIT spinout SurgiBox – were featured on TIME’s Best Inventions of 2023 list.

Researchers at MIT have developed a conceptual design for a system that can efficiently produce “solar thermochemical hydrogen,” reports Xinhua. “The system harnesses the Sun's heat to directly split water and generate hydrogen -- a clean fuel that can power long-distance trucks, ships, and planes, while in the process emitting no greenhouse gas emissions.”

WBUR reporter Daniel Ackerman spotlights Sublime Systems, an MIT startup working to develop “construction-ready, emissions-free cement.” Ackerman explains that: “Sublime’s new approach uses electricity instead of heat. That means the process can be powered with renewable energy rather than fossil fuels. The method also prevents carbon dioxide from escaping the carbon-rich limestone during combustion.”

Insider reporter Katie Hawkinson explores how MIT researchers developed a new solar-powered desalination system that can remove the salt from seawater for less than the cost of U.S. tap water. Creating a device that relies on solar power, “eliminates a major financial barrier, especially for low-income countries experiencing water scarcity,” Hawkinson explains.

In an article about how researchers are exploring why ancient Roman and Mayan buildings are still standing, AP reporter Maddie Burakoff highlights how researchers from MIT found that an ancient Roman technique for manufacturing concrete gave the material “self-healing” properties. “We don’t need to make things last quite as long as the Romans did to have an impact,” says Prof. Admir Masic. “If we add 50 or 100 years to concrete’s lifespan, “we will require less demolition, less maintenance and less material in the long run.”

MIT researchers have developed a new desalination system that uses solar energy to convert seawater into drinkable water, reports Tony Ho Tran for the Daily Beast. The device could make it possible to, “make freshwater that’s even more affordable than the water coming from Americans’ kitchen faucets.”

The Hill reporter Sharon Udasin writes that MIT researchers have developed a new solar-powered desalination device that “could last several years and generate water at a rate and price that is less expensive than tap water.” The researchers estimated that “if their model was scaled up to the size of a small suitcase, it could produce about 4 to 6 liters of drinking water per hour,” writes Udasin.

Boston Globe reporter Macie Parker spotlights the new John A. Volpe National Transportation Systems Center in Kendall Square, the first building to open in MIT’s redevelopment of the 14-acre Volpe site that will ultimately include “research labs, retail, affordable housing, and open space, with the goal of not only encouraging innovation, but also enhancing the surrounding community.” Parker highlights the green technology included in the new Volpe Center: solar panels; triple-paned glass; electric vehicle charging stations; a rainwater reclamation and reuse system; and green and cool roof technology to lower energy use.
