Researchers at MIT and elsewhere have developed a swallowable electronic capsule that can be used to help diagnose sleep apnea and other sleep disorders, reports Ian Randall for Newsweek. “Conventional laboratory and home sleep studies require the patient to be attached to many different sensors,” says Prof. Giovanni Traverso. “As you can imagine, trying to sleep with all of this machinery can be challenging. [The] ingestible capsule just requires that the patient swallow the vitamin-sized pill. It's easy and unobtrusive and can accurately measure both respiratory rate and heart rate while the patient sleeps."

George Hadjigeorgiou MSc '98 co-founded Zoe, a personalized nutrition program that “aims to improve gut and metabolic health,” reports Julia Kollewe for The Guardian. “Zoe has identified almost 5,000 never-before-seen gut bacteria,” writes Kollewe. “Of those, 100 were strongly associated with health across all 35,000 participants – 50 good and 50 bad. This feeds into the app and members’ personalized scores will be updated over time”

President Biden has awarded Prof. Emeritus Subra Suresh ScD '81, the former dean of the MIT School of Engineering, the National Medal of Science for his “pioneering research across engineering, physical sciences, and life sciences,” reports Alexa Gagosz for The Boston Globe. Prof. James Fujimoto '79, SM '81, PhD '84, research affiliate Eric Swanson SM '84, and David Huang '85, SM '89, PhD '93 were awarded the National Medal of Technology and Innovation, “the nation’s highest award for technical achievement.”

A number of MIT spinouts and research projects – including the MOXIE instrument that successfully generated oxygen on Mars, a new solar-powered desalination system and MIT spinout SurgiBox – were featured on TIME’s Best Inventions of 2023 list.

Researchers at MIT have developed a conceptual design for a system that can efficiently produce “solar thermochemical hydrogen,” reports Xinhua. “The system harnesses the Sun's heat to directly split water and generate hydrogen -- a clean fuel that can power long-distance trucks, ships, and planes, while in the process emitting no greenhouse gas emissions.”

Insider reporter Katie Hawkinson explores how MIT researchers developed a new solar-powered desalination system that can remove the salt from seawater for less than the cost of U.S. tap water. Creating a device that relies on solar power, “eliminates a major financial barrier, especially for low-income countries experiencing water scarcity,” Hawkinson explains.

MIT researchers have developed a new desalination system that uses solar energy to convert seawater into drinkable water, reports Tony Ho Tran for the Daily Beast. The device could make it possible to, “make freshwater that’s even more affordable than the water coming from Americans’ kitchen faucets.”

The Hill reporter Sharon Udasin writes that MIT researchers have developed a new solar-powered desalination device that “could last several years and generate water at a rate and price that is less expensive than tap water.” The researchers estimated that “if their model was scaled up to the size of a small suitcase, it could produce about 4 to 6 liters of drinking water per hour,” writes Udasin.

Maria Telleria ’08, SM’10, PhD ’13 speaks with Forbes contributor Stuart Anderson about her experience immigrating to the U.S. as a teenager, earning her PhD at MIT, and co-founding a company. “I don’t think I would have had these opportunities if I could not have come to the United States,” said Telleria. “I think it helped me grow by being exposed to two cultures. When you have had to think in two different ways, I think it makes you better understand other people and why they’re different. Coming to America has been an amazing opportunity.”

MIT researchers have developed a new underwater system that could enable long-range and low-power underwater communication, reports Edd Gent for IEEE Spectrum. “The reason why this is really exciting is because now you start opening up many of the coastal monitoring applications,” says Prof. Fadel Adib. “It’s a turning point from this being a technology that is intellectually super interesting that we hope will work, to saying we know that this works and we have a path to deployment.”

MIT researchers have devised a new carbon capture system that “relies on the reaction between CO2 in flue gas and a fine mist of electrically charged particles,” reports Karmela Padavic-Callaghan for New Scientist. The researchers believe their design could be “95 per cent efficient at capturing carbon dioxide, while measuring less than 4 meters long,” Padavic-Callaghan notes. “Their analysis also showed that the approach would reduce capital costs of adding carbon capture to power plants by about 2.6 times compared with current technology.”

Researchers at MIT and elsewhere have developed a medical device that uses AI to evade scar tissue build up, reports Andrew Paul for Popular Science. “The technology’s secret weapon is its conductive, porous membrane capable of detecting when it is becoming blocked by scar tissue,” writes Paul. 

Graduate student Turga Ganapathy is studying the best ways to grow spirulina at home so that the microalgae can be used as a food source, reports WCVB-TV. Spirulina “are complete proteins, meaning that they produce amino acids that the human body cannot synthesize that we usually get from animals or a combination of different plant-based proteins,” says Ganapathy.

Researchers at MIT have developed a supercapacitor, an energy storage system, using cement, water and carbon, reports Macie Parker for The Boston Globe. “Energy storage is a global problem,” says Prof. Franz-Josef Ulm. “If we want to curb the environmental footprint, we need to get serious and come up with innovative ideas to reach these goals.”

Researchers from MIT and BU have developed the Cleana toilet seat, a set of non-electric automatic lifting and lowering toilet seats that aim to make bathrooms more sanitary, reports Rob Way for WHDH.
