MIT scientists are working to fortify coastlines with “architected” reefs that can also provide habitats for fish and marine life, reports Ed Brown for TechBriefs. “We looked at the structure of these reefs and we found some similarities to what we had been doing in fluid mechanics. That led us to the idea of trying to make artificial reefs that we could architect and build in a very directed way,” says Prof. Michael Triantafyllou.
MIT engineers have developed a new adhesive, low-cost hydrogel that can stop fibrosis often experienced by people with pacemakers and other medical devices, reports for Maria Bolevich Interesting Engineering. “These findings may offer a promising strategy for long-term anti-fibrotic implant–tissue interfaces,” explains Prof. Xuanhe Zhao.
MIT researchers have developed a wearable backpack with spider-like limbs to help astronauts maintain stability in space, reports Jess Thomson for Newsweek. The new technology, called Supernumerary Robotic Limbs (SuperLimbs), “could be crucial in future missions to the moon, where gravity is only a sixth of that on Earth and astronauts may struggle to clamber up again after a fall due to their unwieldy space suits,” explains Thomson.
Researchers at MIT have developed SuperLimbs, a pair of wearable robotic limbs that “can physically support an astronaut and lift them back on their feet after a fall,” reports Brain Heater for TechCrunch. “The system, which is still in the prototype phase, responds directly to the wearer’s feedback,” writes Heater. “When sitting or lying down, it offers a constructive support to help them get back up while expending less energy — every extra bit helps in a situation like this.”
Prof. Asegun Henry founded Fourth Power, a startup using new technology to cut the cost of storing renewable energy, reports Adele Peters for Fast Company. The technology is designed “to tap into excess renewable energy,” explains Peters. “That energy heats up liquid tin, which flows down carbon pipes to heat up the blocks. When the grid needs electricity again, the system generates it using special solar panels that run on the white-hot light from the pipes rather than sunshine. Because the system was designed for durability, the team expects it to last for three decades—far longer than lithium-ion batteries, which quickly degrade.”
Prof. Kripa Varanasi and Vishnu Jayaprakash SM '19, PhD '21 co-founded AgZen, an MIT spinoff that is developing new technologies to improve the performance and effectiveness of pesticide treatments, reports The Economist. The new technologies “could reduce the total amount of fungicides and insecticides sprayed over complete crops by some 90%, as well as cutting the amount of adjuvants required,” writes The Economist.
Prof. Giovanni Traverso and colleagues have developed a new ingestible sensor that could be used to help diagnose gastrointestinal conditions, reports Jeremy Hsu for New Scientist. “Eventually, the futuristic device could provide treatments for gut illnesses through electrical stimulation via additional electrodes embedded in the sensor,” Hsu notes.
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.”
MIT researchers have developed a new type of spring-like device that uses a flexible element to help power biohybrid robots, reports Brian Heater for TechCrunch. “The muscle fiber/flexure system can be applied to various kinds of robots in different sizes,” Heater writes, adding that the researchers are, “focused on creating extremely small robots that could one day operate inside the body to perform minimally invasive procedures.”
Prof. Kripa Varanasi co-founded Alsym Energy, a startup “developing rechargeable batteries that won’t be based on lithium or cobalt,” reports Hiawatha Bray for The Boston Globe. “The founders said they expect to build batteries that match the performance of today’s lithium-ion cells but at about half the cost,” writes Bray.
NASA astronaut Christopher Williams PhD '12 shares his excitement over the upcoming solar eclipse with Space.com Elizabeth Howell, noting he is most excited that the celestial event will provide unique views of the sun’s outer atmosphere. Williams previously conducted radio astronomy research and helped build the Murchison Widefield Array in Australia during his time at MIT. "It was an incredible experience, because I got to both work on the cosmology and the science behind that,” recalls Williams.
Prof. Emeritus Donald Sadoway co-founded Boston Metal, an MIT startup that has developed a carbon-free steel manufacturing process, reports Amy Feldman for Forbes. “Boston Metal’s process – which uses an electricity conducting, molten-metal proof anode to liquify iron ore, separating the pure metal without harmful byproducts – allows factories to create carbon-free steel as long as they use a clean energy source, such as hydroelectric power,” explains Feldman. “It also can create steel from lower-grade ores rather than relying on scarce high-grade ones. That’s an important advantage in terms of both cost and availability compared to other methods of making green steel, according to the company.”
TechCrunch reporter Haje Jan Kamps spotlights AgZen, an MIT startup that has developed a new tool that optimizes the use of pesticides to avoid over application. “The real winner in all of this may prove to be public health and the environment,” writes Jan Kamps. “By reducing foliar pesticide usage by 30% to 50%, AgZen’s technology might help mitigate [environmental] impacts, aligning with the critical need for improved spray efficiency highlighted in recent reports.”
