Writing for Bloomberg, David Zipper, senior fellow at the MIT Mobility Initiative, highlights the impact of the robotaxi industry on public transportation. “Transit-robotaxi synergy is an enticing message at a time when public transportation agencies face a dire funding shortage, and it could especially resonate among left-leaning residents in places like the Bay Area who value buses and trains even if they seldom use them,” writes Zipper. “But caveat emptor: The robotaxi industry’s embrace of public transportation conceals a wolf in sheep’s clothing.” 

Prof. Admir Masic speaks with New York Times reporter Amos Zeeberg about his research studying the benefits of lime clasts – a material used in ancient Roman infrastructure. According to Masic’s research, “these lime clasts were actually reservoirs of calcium that helped fill in cracks, making the concrete self-healing,” writes Zeeberg. “As cracks formed, water would seep in and dissolve the calcium in the lime, which then formed solid calcium carbonate, essentially creating new rock that filled in the crack.”

Prof. Jessika Trancik speaks with BBC reporter Isabelle Gerretsen about the future of electric vehicles and  how shifting to EVs can help reduce carbon emissions. Trancik and her research lab developed an online tool, dubbed Carboncounter, that can analyze the climate impact of different vehicles. “A shift to an electric vehicle is one of the single most impactful decisions that someone can make if they want to reduce their own emissions," explains Trancik. 

MIT researchers have developed “a new type of reconfigurable masonry using 3D-printed recycled glass,” reports Srishti Gupta for Interesting Engineering. “The team has developed robust, multilayered glass bricks shaped like figure eights,” explains Gupta. “These bricks are designed to interlock seamlessly, similar to LEGO pieces, making them versatile and easy to assemble.” 

Designboom reporter Matthew Burgos spotlights how MIT engineers “3D printed recycled glass and produced robust LEGO-like bricks for buildings and facades.” The researchers found that “in mechanical testing, a single 3D printed recycled glass brick can withstand pressures similar to those of a concrete block,” Burgos explains. “This means that the material can be just as robust as concrete, making it ideal for construction.”

Researchers at MIT have developed “3D-printed glass blocks shaped like a figure eight that snap together like LEGOs,” reports Brian Heater for TechCrunch. “The team points to glass’ optical properties and its ‘infinite recyclability’ as reasons for turning to the material,” writes Heater. 

MIT researchers have developed a new filtration material, created from natural substances, that could be used to remove “forever chemicals” like PFAS and heavy metals from drinking water, reports Matt Fortin for NBC Boston. "That's a huge advantage of our system, which is that we are using fully renewable, biodegradable and compatible material to resolve this long-lasting problem," explains postdoc Yilin Zhang. 

Los Angeles Times reporter Rosanna Xia spotlights Prof. Susan Solomon’s new book, “Solvable: How We Healed the Earth, and How We Can Do It Again,” as a hopeful remedy to climate anxiety. “An atmospheric chemist at MIT whose research was key to healing the giant gaping hole in our ozone layer, Solomon gives us much-needed inspiration — and some tangible ways forward,” explains Xia. 

Writing for Forbes, Peter Evans PhD '05 identifies used electric vehicle (EV) batteries as the next billion-dollar circular marketplace, noting the possibility of significant search, bargaining and enforcement cost savings. Given large volumes of used batteries won’t be available soon, he acknowledges risk, but “creating a successful national circular EV battery marketplace can be not only a billion-dollar opportunity but an important step toward a more sustainable and resource-efficient future,” he argues.

MIT researchers have developed a new filtration material capable of removing PFAS and heavy metals from water while possessing “antimicrobial properties that prevent the filters from becoming fouled over time,” reports Sujita Sinha for Interesting Engineering. “By combining silk and cellulose and using a method that aligns the silk molecules into nanofibrils, [the researchers] created a hybrid material with unique properties perfect for water filtration,” explains Sinha. 

Prof. Asegun Henry has been named a 2024 Grist honoree for his work developing a “sun in a box,” a new cost-effective system for storing renewable energy, reports Grist. Based on his research, Prof. Henry has founded Fourth Power, a startup working to build a prototype system that will hopefully “allow us to decarbonize electricity,” says Henry. 

A Nature editorial discusses the live music industry’s increasing commitment to sustainability, going beyond actions such as bottle recycling to addressing band travel, equipment shipping and set construction. Researchers from MIT’s Environmental Solutions Initiative have “undertaken a project co-funded by the Warner Music Group, Live Nation and Coldplay to analyze the carbon footprint of the live music industry, initially in the United Kingdom and United States, and suggest practical mitigating measures.”

Anurag Bajpayee MS '08, PhD '12 and Prakash Govindan PhD '12 founded Gradiant, an MIT startup “trying to reduce both costs and energy while eliminating chemicals” in water, reports Diana Olick for CNBC. “We take highly contaminated wastewater which contains solvents, which contains dissolved salt, which contains organics, and we eliminate the entire liquid waste,” says Govindan.

Found Energy, co-founded by Peter Godart '15, SM '19, PHD '21, has developed a method for transforming aluminum scrap metal into energy, reports Hiawatha Bray for The Boston Globe. “The Found Energy system could replace fossil fuel with aluminum-generated hydrogen, a gas that burns at up to 4,000 degrees Fahrenheit, but produces no waste carbon,” writes Bray. 

Plonts, a plant-based cheese company co-founded by Nathaniel Chu PhD '19, uses microbes to develop “nutritious, inexpensive and sustainable” cheese alternatives, reports Christine Hall for TechCrunch. Chu says “microbes, whether mold, bacteria or yeast, are important to create that flavor. The microbes themselves are tiny sacs of hundreds of different enzymes with many different combinations,” writes Hall.
