Writing for the Boston Business Journal, MITEI Director William Green emphasizes that in order to address the climate crisis, "we need to convene universities, industry, and government to address the challenges of every sector including construction, manufacturing, agriculture, and the electric grid." Green notes: "We at MIT are searching for real climate solutions that the public will adopt, and that merit the huge investments necessary for wide deployment. By working collaboratively to solve these complex issues we will successfully address the greatest threat facing humanity today." 

Researchers from MIT and elsewhere have developed a new technique that removes lead from water using repurposed beer yeast, reports Boston 25 News. The researchers “developed a hydrogel capsule to hold the yeast after it is cleaned, freeze-dried, and ground into a powder,” explains Boston 25. “Researchers said the yeast capsules could be modified to remove other dangerous contaminants from water, including PFAS and microplastics.” 

Prof. Sara Seager, Prof. Robert Langer and Prof. Nancy Kanwisher have been awarded the 2024 Kavli Prize for their work in the three award categories: astrophysics, nanoscience, and neuroscience, respectively, reports Michael T. Nietzel for Forbes. According to the Norwegian Academy of Science and Letters, this award honors scientists with outstanding research “that has broadened our understanding of the big, the small and the complex,” writes Nietzel. 

Prof. Kristala Prather, head of MIT's Department of Chemical Engineering, speaks with Nature reporter Alessio Lavino about what inspired her research on metabolic engineering and how her work in industry helped shape her career in academia. “The potential to educate, encourage and support the next generation of scientists and engineers in an educational setting gives me a chance to amplify my impact far beyond what I could ever personally do as an individual,” says Prather. “I cannot think of any higher honor than serving in a capacity that enables me to facilitate their emergence.”

Researchers at MIT have created a noise-blocking sheet of silkworm silk that could “greatly streamline the pursuit of silence,” reports Andrew Chapman for Scientific American. “The silk sheet, which is enhanced with a special fiber, expands on a technology also found in noise-canceling headphones,” explains Chapman. “These devices create silence by sampling the ambient noise and then emitting sound waves that are out of phase with those in the environment. When the ambient and emitted waves overlap, they cancel each other out.” 

Researchers at MIT and elsewhere have developed a filter from used brewery yeast capable of removing lead and other metals from water, reports Rich Johnson for NewsNation. “Through a process called biosorption, the yeast can bind to lead, as well as the metals commonly used in electronic components,” explains Johnson. “That, say the researchers, could be a game-changer when recycling those metals. But the more valuable impact may be the ability to filter drinking water, starting with home faucets, and eventually scaling up to serve municipal water systems.” 

Science reporter Jennifer Sills asked scientists to answer the question: “Imagine that you meet all of your research goals. Describe the impact of your research from the perspective of a person, animal, plant, place, object, or entity that has benefited from your success.” Xiangkun (Elvis) Cao, a Schmidt Science Fellow in the MIT Department of Chemical Engineering, shares his response from a photon’s perspective. “I am a photon,” writes Cao. “I started my journey entangled with my significant other at the beginning of the Universe. In the past, humans couldn’t understand me, but then physicists created a quantum computer. At last, I have been reunited with my life partner!”

Milena Pagán '11 speaks with Boston.com reporter Linda Laban about re-opening her bagel shop, Rebelle Bagels, in Kendall Square. Pagán, who earned a degree in chemical engineering before diving into the culinary world, explains that she felt it was a natural transition from engineering to food. “It’s not a traditional path, but they do have a lot in common,” Pagán explains. “Making bagels feels a lot like engineering.”

Prof. Gregory Rutledge speaks with The Ringer reporter Claire McNear about the science behind nanofibers and whether it's possible to create ultrathin and ultrastrong nanofibers that are invisible to the human eye, as shown in the science fiction series “3 Body Problem.” Rutledge explains that: “Given that a human hair is about 50 micrometers in diameter, a fiber 100 times smaller would be about 500 nanometers in diameter. Such fibers are routinely made by electrospinning, as well as by a couple of other technologies. Metal wires can also be drawn that small.”

Prof. Emeritus Donald Sadoway co-founded Boston Metal, an MIT startup that has developed a carbon-free steel manufacturing process, reports Amy Feldman for Forbes. “Boston Metal’s process – which uses an electricity conducting, molten-metal proof anode to liquify iron ore, separating the pure metal without harmful byproducts – allows factories to create carbon-free steel as long as they use a clean energy source, such as hydroelectric power,” explains Feldman. “It also can create steel from lower-grade ores rather than relying on scarce high-grade ones. That’s an important advantage in terms of both cost and availability compared to other methods of making green steel, according to the company.”

Priyadarshi Panda PhD '11 – founder of International Battery Company, a startup developing lithium-ion battery cells for electric vehicles – is working to “bridge the demand-supply gap in the growing EV market in India,” reports Jagmeet Singh for TechCrunch. “There is a lot of demand in the Indian market, which is satisfied through imports right now,” says Panda. “No cells are being manufactured in India. So, we want to participate in that journey in India.”

Forbes contributor William Haseltine spotlights how MIT researchers developed a biosensor ingestible capsule that can gather and transmit information on a patient’s condition to a physician. Haseltine notes that “aside from respiratory and heart rate monitoring, future applications for the pill could come from alterations in its design, leading to other avenues of health monitoring. These may include digestive health, blood sugar monitoring and cancer cell detection.” 

Researchers from MIT and elsewhere are developing an electronic pill that can “measure heart rate, breathing rate and core temperature – from inside a human stomach,” reports Celia Ford for Wired. “We have a solution that’s relatively simple and enables access broadly,” says Prof. Giovanni. “I think that can be really transformative.”

Prof. Brad Olsen speaks with Slate reporter Anna Gibbs about the use of bio-based polymers in place of plastics. Olsen says “for this approach to take off, though, the cost of bio-based polymers will need to go down. When you’re producing something that’s identical but charging more, really what you’re charging more for is the fact that it’s made with green carbon.” 

Forbes reporter Nancy Wang spotlights Tara Bishop '97 and Eileen Tanghal '97, co-founders of Black Opal Ventures, a venture capital firm focused on health tech. “Tara and Eileen’s story at Black Opal Ventures is a testament to how diversity and innovation can disrupt traditional landscapes,” writes Wang. “Their pioneering strategies and investments herald a new era for healthcare venture capitalism, where diversity and technology converge to create a more inclusive and impactful future.”
