Lithios, a startup cofounded by Mohammad Alkhadra PhD '22 and Prof. Martin Bazant, is developing “a clean and relatively cheap way to access vast amounts of lithium,” reports Hiawatha Bray for The Boston Globe. “Lithios has developed a lithium-absorbing material that can be made into electrodes using the same technologies created to make electrodes for lithium-ion batteries,” explains Bray.
The Boston Globe’s Angelina Parrillo interviews Jasmina Aganovic ’09 about her beauty company Arcaea, which reconstructs data from extinct flowers to produce fragrances. “I viewed fragrance as this remarkable emotional storytelling category and people don’t view science as being associated with creativity, emotion, or storytelling,” Aganovic says. “I think that that’s very far from the truth.”
Prof. Michael Strano joins “Somewhere on Earth” podcast host Gareth Mitchell to discuss how he and his colleagues developed tiny batteries that could be used to power cell-sized robots. Roughly the thickness of a human hair, the new battery can create a current by capturing oxygen. “I would say we're making the LEGOs, the building blocks that go into robots,” Strano says. “We’re building the parts and it's an exciting time for the field.”
Falmouth’s Ben & Bill’s Chocolate Emporium has unveiled a new chocolate candy named Dr. Bob’s Dark Chocolate Maple Syrup Cream – inspired by Prof. Bob Langer’s love of maple, reports Jon Chesto in The Boston Globe. “To make the Dr. Bob’s candy, the staff takes the maple cream chocolates and then drizzles maple syrup over them as a topping,” writes Chesto.
Researchers at MIT have developed tiny batteries capable of powering cell-sized robots that can “execute tasks as varied as targeting drug delivery inside the human body to checking pipelines for gas leaks,” reports Brian Heater for TechCrunch. “Despite the barely visible size, the researchers say the batteries can generate up to 1 volt, which can be used to power a sensor, circuit or even a moving actuator.”
Prof. Martin Bazant speaks with Wired reporter Emily Mullin about the importance of proper battery disposal to reduce waste and ensure the materials can be reused. “What we don’t want is to be losing critical minerals from the supply chain,” explains Bazant. “We have to be able to recycle them.”
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 have developed a fiber capable of suppressing sound that is made up of “silk, canvas and other common materials,” reports Charlie McKenna for MassLive. “The silk is barely thicker than human hair and is made by heating the materials and drawing them into a fiber,” explains McKenna. “Since each material flows at the same temperature, they can be pulled into a fiber while maintaining their structure.”
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.”
MIT researchers have developed “an ultra-thin silk fabric embedded with a special piezoelectric fiber that can vibrate to cancel out noise in a room,” reports Bob McDonald for CBC. “The researchers want to further study how changing elements of the fabric — such as the number of piezoelectric fibers and the voltage they apply to it, the direction they're sewn into the fabric, and the size of the pores in the fabric — can improve on their findings,” writes McDonald.
Interesting Engineering reporter Sujita Sinha spotlights how MIT researchers crafted a special silk fabric capable of blocking sound. “Inside this special material is a fiber that springs to life when an electrical charge is applied,” explains Sinha. “The fabric starts shaking when it hears sound, which helps stop noise in two different ways.”
