In an interview with Smithsonian Magazine’s Diane Tedeschi, alumnus Mike Massimino SM ’88, PhD ’92 discusses working on NASA’s space shuttle as a mission specialist and repairing the Hubble Space Telescope. “Nothing can really prepare you, though, for the overwhelming beauty that you see—the emotion of it [space],” says Massimino. “When you see the beauty of Earth and the stars and the Moon and everything around you, it’s so inspiring. But as far as your job goes, you’re 100-percent ready.”  

Hertha Metals, a startup founded by alumna Laureen Meroueh SM ’18, PhD ’20, “has developed a way to produce high-purity iron needed in the magnets used in everything from electric vehicles to humanoid robots,” writes reporter Stephanie Findlay for the Financial Times. “Hertha is breaking ground on a 10,000-tonne-a-year commercial facility today on the outskirts of Houston to produce the metal,” Findlay highlights. “The company plans to produce the first steel-grade iron in the fourth quarter of next year and start producing the high-purity iron by 2028.” 

MIT startup Alsym Energy, cofounded by Prof. Kripa Varanasi, has developed an alternative to lithium-ion batteries using sodium ions, writes Morgan Clendaniel for Fast Company. “The battery is nonflammable and nontoxic, allowing it to be placed in more sensitive areas and saving money on cooling systems that often have to be co-installed with large lithium batteries,” explains Clendaniel.  

VulcanForms, a 3-D printing manufacturer that produces “complicated metal parts for a variety of industries, at speed and at scale,” founded by Martin C. Feldmann ’14 and Prof. John Hart, is expected to double its workforce within the next year, reports Jon Chesto for The Boston Globe. “We were born out of MIT, we’ve kind of got our DNA here,” says Kevin Kassekert, chief executive of VulcanForms. “Massachusetts is a place where you can attract the best talent in the world.” 

MIT researchers have developed a paper-thin biohybrid robot “capable of swimming that is powered by living muscle cells instead of a traditional motor,” writes Forbes’ Conor Murray. The muscle cells are engineered to respond to flashes of light, allowing the robot to swim through mazes. The researchers believe that in the future biohybrid robots could eventually be used for everything from precision microsurgery to exploring fragile environments.  

MIT researchers have invented a digestible, bioresorbable battery that can deliver drugs directly to the GI tract, reports Smithsonian Magazine’s Sara Hashemi. Prof. Giovanni Traverso and his colleagues “made two versions of the battery of different sizes and voltages,” writes Hashemi. “Exposing them to an acidic liquid similar to gastric fluid revealed they would function normally in the stomach for about three days.” 

The Economist highlights MIT researchers’ new “paper-based battery whose components are safely absorbed by the body,” to help deliver drugs to the GI tract more effectively. “The new battery is a stack of magnesium, gel and chemically active paper—all coated in wax to protect it from the harsh environment of the gut. It is also compact, taking up only about a quarter of the space inside a standard gelatine capsule, leaving plenty of room for the device it is to power, as well as other useful payloads, such as a drug.”  

MIT researchers have developed an ingestible battery that could be used to monitor drug delivery and avoid the need for surgery; a “milestone towards potential human use for health monitoring and treatments,” writes Michael Peel for the Financial Times. Improving the effectiveness of therapies “moves the technology beyond a materials demonstration toward an integrated biomedical system,” says Prof. Giovanni Traverso, senior author of the study.  

Prof. Anette “Peko” Hosoi, co-founder of the MIT Sports Lab, and Andrew Byron, assistant coach for the MIT Football team, join Edgar B. Herwick III, host of GBH’s “The Curiosity Desk,” to discuss athletic intelligence and football IQ. “One of the special things about football is that it’s an incredibly complicated game compared to other games because there are very specialized positions,” says Hosoi. “Everybody has a very special role and there are a lot of players on the field at once.”  

MIT researchers have developed an AI-powered robotic therapy system that combines wearable force sensors and camera recordings of physical therapists’ movements to provide personalized therapy to patients, writes Newsweek’s Claudia Tanner. “Robotic assistance will allow patients to practice exercises more often while still receiving support tailored to their abilities,” says Johannes Lachner, who completed this work as a postdoctoral fellow at MIT. “Our goal is to take a step toward more accessible and personalized physical rehabilitation, giving more patients the opportunity to regain movement and independence.” 

Prof. Raphael Zufferey and his research group developed a winged robot that can swim underwater and fly through the air like a diving bird and “could one day be used to monitor and ultimately help protect the ocean,” reports Tom Page for CNN. “We’re really trying to understand better how birds do this,” says Zufferey. “The other reason we’re doing this is we’re hoping that this becomes (a) future tool for oceanography.” 

MIT spinoff Found Industries’ new Cambridge headquarters and metals processing development center is highlighted by Boston Business Journal's Lucia Maffei. “We are developing electrochemical processes to recover gallium and, in time, indium, and germanium, and antimony and other critical metals directly from existing industrial streams,” says Peter Godart PhD ‘21, Found Industries CEO.  

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.  

Principal Research Scientist John Liu speaks to Manufacturing Dive’s Nathan Owens about MIT’s Technologist Advanced Manufacturing Program (TechAMP), a 12-month-long certificate program designed to "bring experienced technicians into leadership roles with a focus on advanced manufacturing needs.” Says Liu: "We’re looking at developing this elite workforce who bridges the gap. What we’re trying to do is upskill the technician.”
