Researchers at MIT have developed a soft robot that can be controlled by a weak magnetic field and travel through tiny spaces within the human body, reports Andrew Paul for Popular Science. “Because of their soft materials and relatively simple manipulation, researchers believe such mechanisms could be used in biomedical situations, such as inching through human blood vessels to deliver a drug at a precise location,” explains Paul.
Writing for Forbes, Prof. Daniela Rus, director of CSAIL, makes the case that liquid neural networks “offer an elegant and efficient computational framework for training and inference in machine learning. With their compactness, adaptability, and streamlined computation, these networks have the potential to reshape the landscape of artificial intelligence and drive further breakthroughs in the field.”
Sublime Systems, a startup founded by Prof. Yet-Ming Chiang and former MIT postdoc Leah Ellis, is working to decarbonize cement making – a process which currently accounts for eight percent of global carbon emissions. “The world has a huge appetite for cement, and Sublime is working to scale its production to meet it,” writes Casey Crownhart for The Spark, MIT Technology Review’s weekly climate newsletter.
MIT has been selected as the world’s best university in the 2024 QS World University Rankings, reports Cecilia Rodriguez for Forbes. MIT has secured “the top position for the 12th consecutive year,” writes Rodriguez.
Prof. Yang Shao-Horn spoke at the State of the Art Jewelry Summit to discuss the jewelry industry’s impact on carbon emissions and sustainability efforts, reports Caroline Palmer for the Financial Times. Shao-Horn's suggestions to tackle the problem involved a mix of a carbon tax, “which could encourage the use of new technology, including electric vehicles, as well as shifting mining practices away from open site to the development of mobile mining vehicles powered by renewable energy or hydrogen,” writes Palmer.
MIT researchers have discovered an RNA-guided DNA-cutting enzyme in eukaryotes, reports Science. “The researchers speculate that eukaryotic cells may have gained the newly identified editing genes from transposable elements—so-called jumping genes—they received from bacteria,” writes Science.
Former MIT Prof. Edward Fredkin, “a pioneer in artificial intelligence and a maverick theorist,” has died at 88, reports Alex Williams for The New York Times. Williams notes that Fredkin, who worked on Project MAC during his time at MIT, was “fueled by a seemingly limitless scientific imagination and a blithe indifference to conventional thinking.” Prof. Gerald Sussman recalls that “Ed Fredkin had more ideas per day than most people have in a month.”
MIT researchers have identified a new biological editing system that could “potentially be even more precise than CRISPR gene editing,” reports Laura Baisas for Popular Science. The new system, based on a protein called Fanzor, is “the first programmable RNA-guided system discovered in eukaryotes,” Baisas notes.
Researchers from MIT and BU developed the Cleana toilet seat, which is aimed at addressing poor toilet etiquette, reports Katie Thompson for WCVB. “One toilet seat lifts and stays in the up position after the seat is placed down is designed for a more high-traffic commercial space,” writes Thompson. “The residential version, meanwhile, includes a seat and lid that are both designed to automatically lower after use, helping protect the open toilet bowl from small children and pets — as well as creating a better aesthetic look.”
Researchers at MIT have developed an extra-absorbent hydrogel that can draw water from the air, reports Ross Cristantiello for Boston.com. The new hydrogel “could potentially help communities ravaged by drought and make air conditioners more energy-efficient,” writes Cristantiello.
Prof. Yet-Ming Chiang co-founded Sublime Systems, a company that has developed a new method for producing cement that is powered by electrochemistry instead of fossil fuel-powered heat, reports Catherine Clifford for CNBC. “I believe climate change has pushed all of us into an extremely fertile, creative period that will be looked back on as a true renaissance,” says Chiang. “After all, we're trying to re-invent the technological tools of the industrial revolution. There's no shortage of great problems to work on! And time is short.”
Ali Khademhosseini PhD ’05 founded Omeat, a cultivated meat startup that “enables the cultivation of any meat in a way that is orders-of-magnitude more sustainable and humane than the conventional approach,” reports Christine Hall for TechCrunch.
Prof. Marzyeh Ghassemi speaks with Yahoo News reporter Rebecca Corey about the benefits and risks posed by the use of AI tools in health care. “I think the problem is when you try to naively replace humans with AI in health care settings, you get really poor results,” says Ghassemi. “You should be looking at it as an augmentation tool, not as a replacement tool.”
MIT researchers have found that when enhanced with salt, a rubbery hydrogel commonly found in diapers can absorb record amounts of moisture from the air, reports Andrew Paul for Popular Science. “Across a wide variety of humidity conditions, the team’s enhanced hydrogel could swell and absorb impressive amounts of air moisture without leaking,” Paul notes.
MIT researchers have developed a new compact, lightweight design for a 1-megawatt electrical motor that “could open the door to electrifying much larger aircraft,” reports Ed Gent for IEEE Spectrum. “The majority of CO2 is produced by twin and single-aisle aircraft which require large amounts of power and onboard energy, thus megawatt-class electrical machines are needed to power commercial airliners,” says Prof. Zoltán Spakovszky. “Realizing such machines at 1 MW is a key stepping stone to larger machines and power levels.”
