Prof. Desirée Plata speaks with C&EN reporter Prachi Patel about her work “trying to make our chemical processes and industries compatible with human and ecological health.” Says Plata of what she is most proud of in her work: “As professors, we produce papers and patents, but people are the most important thing we produce. The faculty of the world are training the next generation of researchers. There’s a perception right now that AI is going to solve all of our problems, but it cannot without good physical science information. We need a trained workforce. We need patient chemists who want to solve important problems.”

Shiv Bhakta MBA '24, SM '24 and Richard Swartwout SM '18, PhD '21 co-founded Active Surface, a solar tech company that has developed “a new kind of solar collector so thin and flexible it can be attached to anything under the sun,” reports Hiawatha Bray for The Boston Globe. “The company prints solar cells onto a plastic sheet, using methods not too different from those used to print newspapers,” explains Bray. “The resulting cells can generate electric power nearly as efficiently as today’s heavy, thick silicon panels.” 

Inspired by his daily walks, Prof. Elfatih Eltahir and his colleagues have developed a new way to measure how climate change is likely to impact the number of days when it is comfortable to be outdoors, reports Maddie Browning for WBUR. “I find people walking, jogging, cycling and enjoying the outdoors,” says Eltahir. “That's what motivated me to start looking at how climate change could really constrain some of those activities.”

Financial Times reporter Clive Cookson spotlights how MIT researchers have developed a “new filtration material based on natural silk and cellulose that removes a wide range of PFAS, while having antimicrobial properties that prevent fouling by bacteria and fungi.” 

MIT researchers developed a new method to model how climate change will impact the number of “outdoor days” and found that Southern states in the U.S. will lose a significant number of outdoor days, reports Kristin Toussaint for Fast Company. Prof. Elfatih Eltahir explains that the concept of outdoor days is, “an attempt for me to bring the issue of climate change home. When someone tells you global temperatures are going to increase by 3 degrees, that’s one thing. If someone tells you that your outdoor days will be dropping by 20% or 30%, that’s another thing.”

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. Yossi Sheffi, director of the MIT Center for Transportation and Logistics, has been named to the top spot in the Supply Chain Digital list of the top 10 supply chain influencers. Sheffi’s “expertise in systems optimization, risk analysis and supply chain management is covered in his extensive body of work,” writes Libby Hargreaves for Supply Chain Digital. “His consultancy with top enterprises cements him as the leading voice in shaping modern supply chain strategies and addressing emerging industry challenges.” 

Prof. Yossi Sheffi speaks with Boston Globe reporter Hiawatha Bray about the challenges and risks posed by implementing automation, amid the dockworkers strike. Sheffi emphasized the importance of gradually introducing new technologies and offering workers training to work with AI. “There will be new jobs,” says Sheffi. “And we want the current workers to be able to get these new jobs.” 

Prof. Yossi Sheffi speaks with Associated Press reporter Cathy Bussewitz about how automation could impact the workforce, specifically dockworkers. “You cannot bet against the march of technology,” says Sheffi. “You cannot ban automation, because it will creep up in other places... The trick is to make it over time, not do it haphazardly.” 

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. 

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. Charles Harvey is among the scientists who “warn that [carbon] removal technologies aren’t sophisticated enough nor coming online fast enough to reduce emissions to the level we need them to,” reports Tristram Korten for Fast Company. 

Prof. Desirée Plata and her research team have designed “a kind of clay that mimics the behavior of underwater microorganisms to break down methane into water and carbon dioxide,” reports Ivy Scott for The Boston Globe. “The estimates are that you could save a half a degree of warming by 2100 if you cut human-made methane emissions in half, so that’s a pretty big deal,” says Plata. “It’s the only greenhouse gas that can do that. It’s just a question of whether or not we’ll start to see people doing that ... [regionally] and in Massachusetts.”

MIT engineers have developed a new adhesive, low-cost hydrogel that can stop fibrosis often experienced by people with pacemakers and other medical devices, reports for Maria Bolevich Interesting Engineering. “These findings may offer a promising strategy for long-term anti-fibrotic implant–tissue interfaces,” explains Prof. Xuanhe Zhao. 

Researchers at MIT have developed a new measure called “outdoor days,” which describes the number of days per year in which temperatures are comfortable enough for outdoor activities in specific locations around the world, reports Lebawit Lily Girma for Bloomberg News. “Changes in the number of outdoor days will impact directly how people around the world feel climate change,” says Prof. Elfatih Eltahir.
