MIT researchers have designed a recyclable elastic yarn, made from polyethylene, that mimics the stretchiness of spandex-polyester and spandex-nylon blends, the Anthropocene team writes. “[T]he researchers spun a spool of yarn, melted it, and re-spun it into new yarn several times. Even after 10 cycles, the yarn was as strong and flexible as conventional blended fibers,” explains Anthropocene.
MIT researchers have developed a new, breathable hydrogel material that is “packed with microscopic air tunnels inspired by the way human lungs move oxygen” and allows heat and sweat to escape, reports Luis Prada for VICE. “The material proved to be about 10 times more breathable than conventional hydrogels and retained about 95 percent of its airflow even after being stretched 10,000 times,” explains Prada.
MIT researchers have developed a low temperature process to extract battery-grade lithium from spodumene, the most common type of mineral containing lithium, using a reusable liquid reagent, writes Electronic Design’s Lee Goldberg. “The new process uses a liquid reagent to dissolve the rock into the useful forms of its constituent parts — not just battery-ready lithium salts, but also smelter-grade alumina and cement-ready silica,” writes Goldberg. “After the minerals are extracted, the solvent and reagent can be recovered and used again so that waste levels approach zero.”
Smithsonian Magazine’s Sarah Kuta highlights Lecturer Franco Rossi’s work identifying the name of ancient Maya mathematician Sak Tahn Waax, or “White-chested fox,” inscribed in a chamber with murals, hieroglyphs and mathematical texts. One of Waax’s equations, linking the cycles of Mars and Venus to units of time in the Maya calendar, is “meant to concisely and meaningfully show the relationship between these two planets and human counts of time in ways that could then be applied to political ceremony, predictive astronomy and understandings of seasonality,” says Rossi.
GBH Curiosity Desk host Edgar B. Herwick III comes to MIT for a scoop of science, daring Prof. Pablo Jarillo-Herrero to embark on a twisty challenge: describing his work in the field of twistronics in the amount of time it takes to eat a soft serve outside the Eastern Edge Food Hall. “We were just curious,” says Jarillo-Herrero of the inspiration for his work. “We have never been able to change the angle between materials. Whenever you explore or look at something where you’ve never been able to do it, interesting things are going to happen.”
Lecturer Franco Rossi is spotlighted by National Geographic reporter Taylor Mitchell Brown for deciphering the name of ancient Maya mathematician, Sak Tahn Waax, or “White-Chested Fox,” found inscribed in the mural room at the Maya site of Xultún in Guatemala. “You can look at some of these texts forever, and it won't click,” says Rossi. “Then, one day you see it, and it just clicks.”
In a Science article by reporter Laura Martín Agudelo, Lecturer Franco Rossi delves into the discovery of the autograph of the ancient Maya mathematician, Sak Tahn Waax, or “White-Chested Fox” in Xultun, Guatemala. “[T]here’s good evidence for codex book production [at Xultun],” says Rossi. “So if there’s going to be a name … this would be the most logical place.”
Scientific American’s Joseph Howlett highlights how Lecturer Franco Rossi helped discover the name of ancient Maya mathematician, Sak Tahn Waax, or “White-Chested Fox,” which was inscribed in a 1,000-year-old chamber beneath Guatemala. “Rossi showed how the markings on a particular scrap of plaster could be seen as a sort of celestial chronology; the team then reconstructed how the scraps’ symbols tabulated the time it took for planets such as Mars and Venus to come back to the same position, relative to the sun,” writes Howlett.
MIT researchers have created a new building design model that could enable engineers to construct buildings and bridges that use less materials, writes Tech Briefs’ Andrew Corselli. “Traditional topology optimization essentially starts with a blank space and tries to figure out at each point in this blank space: ‘Should there be material,’ ‘should there not be material’ from an efficiency standpoint,” says Prof. Josephine Carstensen. “Our approach populates the space with a bunch of lines that are instead candidates for ‘should there be material’ or ‘should there not be material.’ By using this line approach, we have the opportunity to have more control.”
Using an ordinary fridge magnet to control a microrobot might sound like fiction, but a team of MIT researchers engineered a technique to 3D-print magnetically activated robots and other materials that could be used in medicine and more. MIT graduate students Andrew Chen and Rachel Sun joined Edgar B. Herwick III of GBH’s Curiosity Desk to discuss their work and inspiration. Sun explains that ultimately, they’re “trying to develop these materials for everyday uses that push the frontiers of what’s possible and how we can help people in society.”
MIT engineers have developed a new low-temperature process for extracting battery-grade lithium from hard rock, while also reducing waste, reports Gayoung Lee for Gizmodo. “Mining is essential to technology and therefore to society, yet it is perceived negatively by much of the public as a destructive, polluting industry, in some cases with good reason,” explains Prof. Yet-Ming Chiang. “We hope to help change that perception by showing that there are cleaner, more sustainable ways to do it.”
MIT researchers have developed a new method for precisely moving columns of individual atoms within a material, which could give rise to exotic quantum properties and shed light on quantum behavior, reports Tim Wogan for Physics World. “I’m excited because of the scalability of this that allows us to look at the interactions between the defects rather than just creating a defect itself,” explains Prof. Frances Ross.
Scientific American reporter Bob Henderson spotlights how graduate student Jiaruo Li and Prof. Riccardo Comin are developing a new device for storing digital data using “an exotic kind of magnetism discovered in the same lab the previous year to make the device faster and more energy-efficient than any competing technology.”
According to the 2026 QS World University Rankings, MIT has been earned a No. 1 global ranking in 12 subject areas, including chemical engineering; chemistry; civil and structural engineering; computer science and information systems; data science and artificial intelligence; electrical and electronic engineering; engineering and technology; linguistics; materials science; mechanical, aeronautical, and manufacturing engineering; mathematics; and physics and astronomy, reports Michael T. Nietzel for Forbes.
Researchers at MIT have developed a new 3D printing platform that can “produce a fully functioning linear motor in about three hours,” reports Justin Caffier for Gizmodo. The research team “explained how by retrofitting a printer with enough extruders to handle the various materials needed to make a working motor, they decimated the usual production time for such a device and brought the material costs down to around $0.50,” writes Caffier.
