Fast Company reporter Adele Peters writes that researchers from MIT and other institutions have found that a technique employed by ancient Romans for manufacturing concrete contains self-healing properties and could be used to help reduce concrete’s global carbon footprint. The ancient concrete method could open the “opportunity to build infrastructure that is self-healing infrastructure,” explains Prof. Admir Masic.
Researchers at MIT and elsewhere have found that using ancient Roman techniques for creating concrete could be used to create buildings with longer lifespans, reports Nicola Davis for The Guardian. “Roman-inspired approaches, based for example on hot mixing, might be a cost-effective way to make our infrastructure last longer through the self-healing mechanisms we illustrate in this study,” says Prof. Admir Masic.
Researchers at MIT have found that applying ancient Roman techniques for developing concrete could be used to reduce concrete manufacturing emissions, reports Saul Elbein for The Hill. “Researchers said blocks treated with the method — in which concrete was mixed with reactive quicklime under continuous heat — knit themselves back together within a few weeks after being fractured,” writes Elbein.
MIT researchers have developed paper-thin solar cells that can adhere to nearly any material, reports Elissaveta M. Brandon for Fast Company. “We have a unique opportunity to rethink what solar technology looks like, how it feels, and how we deploy it,” says Prof. Vladimir Bulović.
Writing for The Hill, President L. Rafael Reif emphasizes the importance of “enabling universities to undertake the use-inspired research that will seed future innovations.” He adds: “To secure national leadership and prosperity over time, the U.S. needs to be the birthplace of the new ideas that will determine the future — including the future of semiconductor technology, design, and manufacturing.”
Prof. Kripa Varanasi and Vishnu Jayaprakash PhD ’21, MS ’19 have launched AgZen, a company that is trying to reduce pesticide use through the development of additives that allow more pesticide droplets to stick to plants, reports Ian Mount for Fortune. “Globally, farms are spending about $60 billion a year on these pesticides, and our goal is to try to get them to cut that down while still not compromising on pest control,” says Jayaprakash.
MIT researchers have developed an ultra-thin solar panel that can adhere to any surface for access to immediate power, reports Jules Suzdaltsev for Mashable. “These ultra-portable panels can make the difference in remote regions where emergencies require more power,” writes Suzdaltsev.
Researchers at MIT have developed a new ultrathin solar cell that can adhere to different surfaces providing power on the go, reports Clara McCourt for Boston.com. “The new technology surpasses convential solar panels in both size and ability, with 18 times more power per kilogram at one-hundredth the weight,” writes McCourt.
Popular Science reporter Andrew Paul writes that MIT researchers have developed a new ultra-thin solar cell that is one-hundredth the weight of conventional panels and could transform almost any surface into a power generator. The new material could potentially generate, “18 times more power-per-kilogram compared to traditional solar technology,” writes Paul. “Not only that, but its production methods show promising potential for scalability and major manufacturing.”
Physics World has named two research advances by MIT researchers to its list of the Top 10 Breakthroughs of the Year. Prof. Gang Chen and his colleagues were selected for their work “showing that cubic boron arsenide is one of the best semiconductors known to science.” Prof. Asegun Henry, grad student Alina LaPotin and their colleagues were nominated for “constructing a thermophotovoltaic (TPV) cell with an efficiency of more than 40%.”
MIT scientists have developed a miniature antenna that could one day be used to help safely transmit data from within living cells “by resonating with acoustic rather than electromagnetic waves,” reports Andrew Chapman for Scientific American. “A functioning antenna could help scientists power, and communicate with, tiny roving sensors within the cell,” writes Chapman, “helping them better understand these building blocks and perhaps leading to new medical treatments.”
Washington Post reporter Pranshu Verma spotlights Prof. Kevin Chen’s research creating flying lightning bug robots that could be used to pollinate crops in vertical farms or even in space. “If we think about the insect functions that animals can’t do,” says Chen, “that inspires us to think about what smaller, insect-scale robots can do, that larger robots cannot.”
MIT researchers have developed a new hardware that offers faster computation for artificial intelligence with less energy, reports Kyle Wiggers for TechCrunch. “The researchers’ processor uses ‘protonic programmable resistors’ arranged in an array to ‘learn’ skills” explains Wiggers.
NBC News reporter Kimmy Yam notes that months after having all charges he faced under the “China Initiative” dismissed, Prof. Gang Chen and his colleagues have discovered a new material that can perform better than silicon. "The discovery could have far-reaching effects, as silicon is currently among the most widely used semiconductors, making up the foundation of modern technology from computer chips to smartphones," writes Yam.
Researchers at MIT believe they have found a new semiconductor that's better than silicon, which could open the doors to potentially faster and smaller computer chips in the future, reports Rachel Cheung for Vice. “Cubic boron arsenide has significantly higher mobility to both electronics and their positively charged counterparts than silicon, the ubiquitous semiconductor used in electronics and computers,” explains Cheung.
