MIT researchers have developed a biosensor “the size of a stick of gum that can be implanted under the skin and deliver naloxone if vital signs indicate an overdose,” reports David Ovalle and Elana Gordon for The Washington Post. 

Researchers at MIT and elsewhere have developed a 3D printing method that allows “precise control over color, shade, texture, all with just a single material,” reports Vanesa Listek for 3Dprint.com. This technique “promises a faster and more sustainable solution than traditional approaches relying on multiple materials and nozzle changes,” explains Listek.

Researchers at MIT have developed a “set of wearable robotic limbs to help astronauts recover from falls,” reports Amy Gunia for CNN. “The so-called ‘SuperLimbs’ are designed to extend from a backpack containing the astronauts’ life support system,” explains Gunia. “When the wearer falls over, an extra pair of limbs can extend out to provide leverage to help them stand, conserving energy for other tasks.”

Researchers at MIT and elsewhere have developed “a new method of 3D printing that uses heat-responsive materials to print multi-color and multi-textured objects in one step,” reports Laura Griffiths for TCT Magazine. “The method has so far been tested using three heat-responsive filaments including a foaming polymer with particles that expand as they are heated, and wood and cork fiber-filled filaments,” explains Griffiths.  

Wired reporter Parker Hall spotlights Lila Snyder SM '96, PhD '98 and her impact as CEO of Bose. Snyder  "helped turn a rickety start in the wireless earbud and Bluetooth speaker space into some of the sleekest, best-sounding models on the market," explains Hall. "In a world where management consultants and tech executives are known for stripping companies for parts and raising prices, Snyder and a slimmed-down Bose have maintained the brand’s noise-canceling superiority in the face of stiff competition from Apple, Sony, and others.”

Yamilée Toussaint '08 has founded STEM From Dance – a dance program that combines STEM education and the performing arts as part of an effort to make STEM fields more accessible and engaging. The program currently works with girls of color in cities around the country. “I believe that the solution to some of the world’s most pressing problems relies on these girls being in the room because they have a different set of life experiences,” says Toussaint. “They’re creative, they’re intellectual, they’re curious, they’re artistic, and they’re going to bring a different set of ideas to the table, so we must make sure that they are included.”

Seonghoon Woo PhD '15, Jongwon Choi PhD '17, Young Suk Jo SM '13, PhD '16, and Hyunho Kim SM '14, PhD '18 have co-founded Amogy – a startup company that is using ammonia produced by renewable energy as a carbon-free way to fuel a tugboat, report Jennifer McDermott and Michael Hill for The Associated Press. “Without solving the problem, it’s not going to be possible to make the planet sustainable,” says Woo. “I don’t think this is the problem of the next generation. This is a really big problem for our generation.”

MIT researchers have developed “a new type of reconfigurable masonry using 3D-printed recycled glass,” reports Srishti Gupta for Interesting Engineering. “The team has developed robust, multilayered glass bricks shaped like figure eights,” explains Gupta. “These bricks are designed to interlock seamlessly, similar to LEGO pieces, making them versatile and easy to assemble.” 

Designboom reporter Matthew Burgos spotlights how MIT engineers “3D printed recycled glass and produced robust LEGO-like bricks for buildings and facades.” The researchers found that “in mechanical testing, a single 3D printed recycled glass brick can withstand pressures similar to those of a concrete block,” Burgos explains. “This means that the material can be just as robust as concrete, making it ideal for construction.”

Researchers at MIT have developed “3D-printed glass blocks shaped like a figure eight that snap together like LEGOs,” reports Brian Heater for TechCrunch. “The team points to glass’ optical properties and its ‘infinite recyclability’ as reasons for turning to the material,” writes Heater. 

Writing for Nature, Prof. Ritu Raman explores how she drew upon her childhood experiences attending different schools across three continents to inform her teaching practices. “Although my pedagogy is still very much a work in progress, my current philosophy involves three main factors: pipettes (knowing when to put on some gloves and teach hands-on); practice (learning when to step aside and enable independent exploration); and patience (centering optimism in my view of students and science),” writes Raman. “With pipettes, practice and patience, I hope to embrace and enjoy the nonlinear nature of teaching and learning.”

Boston Globe columnist Scott Kirsner spotlights Prof. Mitchel Resnick, Prof. Neil Gershenfeld, and the late Prof. Emeritus Woodie Flowers and their work developing programs that “get kids excited about, and more proficient in, STEM.” Kirsner underscores: “Each of the initiatives brings some of the hands-on problem solving, messiness, and collaborative prototyping elements of MIT’s culture into the wider world. And they’ve all had a big impact on the way kids learn about technology.”

Prof. Asegun Henry has been named a 2024 Grist honoree for his work developing a “sun in a box,” a new cost-effective system for storing renewable energy, reports Grist. Based on his research, Prof. Henry has founded Fourth Power, a startup working to build a prototype system that will hopefully “allow us to decarbonize electricity,” says Henry. 

During an interview with Lisa Mullins of WBUR’s Here & Now, graduate student Emelie Eldracher '22 shares the excitement she felt after winning the 2024 Paralympics silver medal win in the mixed-four crew and delves into her research at MIT focused on developing a low-cost system to gather biomechanical feedback for athletes and help improve their performance. “I really hope to contribute to the sphere and hopefully we can use AI in a way that influences athletes to help them get that one-hundredth of a second, as our coach likes to say,” Eldracher explains. “Because if you add up all the one-hundredths of a second in a race, that could be the difference between a medal or not.” 

Graduate student Emelie Eldracher '22 has won a silver medal in the Mixed PR3 Coxed Four A Final at the 2024 Paris Paralympics, reports Brendan Kurie for The Boston Globe. “It was the third consecutive silver medal for the United States in the event, but this year’s boat was filled with first-time medalists,” explains Kurie.
