Researchers from MIT and elsewhere have developed a new vaccine that “could be potentially used against a broad array of coronaviruses like the one that causes Covid-19 and potentially forestall future pandemics,” reports Alex Knapp for Forbes. “The vaccine involves attaching tiny pieces of virus that remain unchanged across related strains to a nanoparticle,” explains Knapp.
MIT Profs. Angela Belcher, Emery Brown, Paula Hammond and Feng Zhang have been honored with National Medals of Science and Technology, reports Michael T. Neitzel for Forbes. Additionally, R. Lawrence Edwards '76 received a National Medal of Science and Noubar Afeyan PhD '87, a member of the MIT Corporation, accepted a National Medal on behalf of Moderna. The recipients have been awarded “the nation’s highest honors for exemplary achievements and leadership in science and technology,” explains Neitzel.
Researchers at MIT have developed a “new type of transistor using semiconductor nanowires made up of gallium antimonide and iridium arsenide,” reports Alex Knapp for Forbes. “The transistors were designed to take advantage of a property called quantum tunneling to move electricity through transistors,” explains Knapp.
Researchers at MIT have demonstrated “fully 3D-printed semiconductor-free resettable fuses,” reports Jesse Allen for Semiconductor Engineering. “The researchers plan to further develop the technology to print fully functional electronics and aim to fabricate a working magnetic motor using only extrusion 3D printing,” writes Allen.
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. Moungi Bawendi, a recipient of the 2023 Nobel Prize in Chemistry, speaks with Nobel Prize Conversations host Adam Smith about the joys of visualizing quantum mechanics, the inspiration for his Nobel-prize winning work and his love of music. “Being in a place like MIT and being exposed to engineering and other scientific fields and medicine across the river and Harvard Medical School and a lot of startups around here, you really are exposed to so many things that are so interesting and I love that,” says Bawendi. “Those things give me ideas of how to go back to the lab and take different directions.”
MIT scientists have discovered that metals become harder when heated under certain conditions, reports Isabelle Dume for Physics World. In an interview, Prof. Christopher Schuch says by bombarding metals with tiny bits of sapphire small enough to avoid shock waves, “the result is a clean and quantitative set of data that clearly reveals the counterintuitive ‘hotter-is-stronger’ effect.”
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.
A new study by MIT engineers finds that heating metals can sometimes make them stronger, a “surprising phenomenon [that] could lead to a better understanding of important industrial processes and make for tougher aircraft,” reports Karmela Padavic-Callaghan for New Scientist. “It was just so unexpected or backwards of what you might conventionally see,” explains graduate student Ian Dowding.
MIT physicists have “successfully placed two dysprosium atoms only 50 nanometers apart—10 times closer than previous studies—using ‘optical tweezers,’” reports Darren Orf for Popular Mechanics. Utilizing this technique can allow scientists to “better understand quantum phenomena such as superconductivity and superradiance,” explains Orf.
MIT researchers have uncovered the “photomolecular effect,” a process “that demonstrates for the first time that water can evaporate with no source of heat using light alone,” reports Anthony Cuthbertson for The Independent. The “discovery could impact everything from climate change calculations to weather forecasts, while also opening up new practical applications for things like energy and clean water production,” writes Cuthbertson.
Researchers at MIT have discovered that “light in the visible spectrum is enough to knock water molecules loose at the surface where it meets air and send them floating away,” reports Michael Franco for New Atlas. “While the distinction between light-caused evaporation and heat-caused evaporation might not seem like a big one, the researchers say it could not only have a big impact on the way future evaporative projects are executed, but that it could also explain a long-standing discrepancy involving clouds,” writes Franco.
Interesting Engineering reporter Rizwan Choudhury spotlights a new study by MIT researchers that finds light can cause evaporation of water from a surface without the need for heat. The photomolecular effect “presents exciting practical possibilities,” writes Choudhury. “Solar desalination systems and industrial drying processes are prime candidates for harnessing this effect. Since drying consumes significant industrial energy, optimizing this process using light holds immense promise.”
Writing for MIT Technology Review, Georgina Gustin chronicles the research journey of Polina Anikeeva, the MIT scientist and engineer who developed flexible brain probes to stimulate neurons and potentially treat neurological disorders. In 2017, Anikeeva became fascinated by the hypothesis that Parkinson’s might be linked to pathogens in the digestive system. Today she and her team use specialized devices to explore the brain-gut connection. “This is a new frontier,” Anikeeva says.
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.”
