Found Energy, co-founded by Peter Godart '15, SM '19, PHD '21, has developed a method for transforming aluminum scrap metal into energy, reports Hiawatha Bray for The Boston Globe. “The Found Energy system could replace fossil fuel with aluminum-generated hydrogen, a gas that burns at up to 4,000 degrees Fahrenheit, but produces no waste carbon,” writes Bray. 

Chanyeol Choi MS '19, PhD '21 and Subeen Pang MS '21, PhD '24 cofounded Linq, an AI startup that “helps hedge funds speed up their research into thousands of listed companies worldwide,” reports John Kang for Forbes. The company’s software “automates time-consuming equity research tasks, such as scanning for company announcements and news, building financial models and summarizing earnings reports and call transcripts,” explains Kang. 

Amrita Saigal '10 is the founder and CEO of Kudos, a company that has developed a “sustainable diaper that uses some plastic but is 100% lined with cotton and incorporates other degradable materials like sugarcane and trees,” reports Gabrielle Fonrouge for CNBC. “I care so much about being premium, but accessible,” says Saigal. “That is exactly what I want to do, so that we are accessible to as many people, and cleaner materials are not out of reach.”

Prof. Kripa Varanasi and Vishnu Jayaprakash SM '19, PhD '22  founded AgZen, a company aimed at reducing pesticide use by employing a feedback-optimized spraying system, reports Steven Savage for Forbes. Savage notes that for the researchers behind AgZen, “MIT turned out to be a good place to work on the specific imaging technology and on the AI needed to translate that into a practical solution for farmers.”

Prakash Govindan PhD '12 and Anurag Bajpayee SM '08 PhD '12 co-founded AlkaLi, a startup working to extract lithium from brine and process it for use in batteries, reports Amy Feldman for Forbes. AlkaLi uses resins and membranes to more easily extract the lithium from brine, then relies on its own technology to concentrate the mineral, which ultimately is precipitated into a solid for use in batteries,” writes Feldman. 

Researchers from MIT have developed “sustainable, offshore, hydrodynamic,” artificial reef structures capable of dissipating “more than 95% of an incoming wave’s total energy,” reports Nick Warburton for Materials World. The design “comprises vertical cylinders with four rudder-like slats attached to them, so that water can flow through the structure to generate 'swirling masses of water' or large eddies,” explains Warburton. 

Prof. Bob Langer and Prof. Giovanni Traverso have co-founded Syntis Bio, a biotech company that will use technology to “coat the stomach and potentially other organ surfaces, [change] the way that drugs are absorbed or, in the case of obesity, which hormones are triggered,” reports Allison DeAngelis for STAT. 

Prof. Seth Lloyd and other physicists have begun to show that in the quantum realm, theoretical routes to the past called time loops might be closer to reality, writes New Scientist’s Miriam Frankel. When first publishing his ideas about quantum time loops, Lloyd says he “probably wouldn’t have done it” given all the questions received about time travel, but now testing time loops is experimentally feasible.

MIT have developed a new ingestible vibrating capsule that could potentially be used to aid weight loss, writes Newsweek’s Robyn White. Prof. Giovanni Traverso said the capsule “could facilitate a paradigm shift in potential therapeutic options for obesity and other diseases affected by late stomach fullness.”

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.”
