Reuters reporter Will Dunham writes that a new study by MIT researchers uncovers the secret ingredient that made ancient Roman concrete so durable and could “pave the way for the modern use of a replicated version of this ancient marvel.” Prof. Admir Masic explains that the findings are “an important next step in improving the sustainability of modern concretes through a Roman-inspired strategy.”
A review led Prof. Marzyeh Ghassemi has found that a major issue in health-related machine learning models “is the relative scarcity of publicly available data sets in medicine,” reports Emily Sohn for Nature.
Researchers from the MIT-IBM Watson AI Lab and the Harvard Natural Language Processing Group developed the Giant Language model Test Room (GLTR), an algorithm that attempts to detect if text was written by a bot, reports Megan Morrone for Fast Company. “Using the ‘it takes one to know one’ method, if the GLTR algorithm can predict the next word in a sentence, then it will assume that sentence has been written by a bot,” explains Morrone.
Astronauts aboard the International Space Station completed an experiment to test a system developed by researchers from MIT’s Space Exploration Initiative that would allow astronauts to build parts in space, reports Pranshu Verma for The Washington Post. The new system could allow astronauts to build and modify space stations “quicker, cheaper and with less complexity,” explains Ariel Ekblaw, director and founder of the Space Exploration Initiative. “It starts to unlock more opportunities for exploration.”
Wall Street Journal reporter David Wainer spotlights a 2021 study conducted Prof. Andrew Lo and his colleagues that investigated “what happened to innovation when drug companies were no longer able to resort to one of their favorite tactics: paying generic makers to stay off the market.”
MIT researchers have discovered that ancient Romans used lime clasts when manufacturing concrete, giving the material self-healing properties, reports Katie Hunt for CNN. "Concrete allowed the Romans to have an architectural revolution," explains Prof. Admir Masic. "Romans were able to create and turn the cities into something that is extraordinary and beautiful to live in. And that revolution basically changed completely the way humans live."
Scientists from MIT and other institutions have uncovered an ingredient called quicklime used in ancient Roman techniques for manufacturing concrete that may have given the material self-healing properties, reports Jacklin Kwan for Science Magazine. When the researchers made their own Roman concrete and tested to see how it handled cracks, “the lime lumps dissolved and recrystallized, effectively filling in the cracks and keeping the concrete strong,” Kwan explains.
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.
Asimov - an MIT spinout co-founded by Prof. Christopher Voigt, Alec Nielsen PhD ’16, Raja Srinivas PhD ’16, and Boston University Prof. Douglas Densmore - is a biotechnology company developing tools to design living systems, reports John Cumbers for Forbes. “Every cell is capable of computing. Perceiving environmental signals, information processing, turning genes on and off,” says Nielsen. “The ability to engineer this gift of evolution is, in my view, going to be the most meaningful and impactful technology that humans have ever developed.”
New research by Prof. David Autor finds that in the U.S. the fast wage growth underway likely reflects a more competitive labor market for workers, writes Martin Sandbu for the Financial Times. “If more workers than before are shifting from worse-paid to better-paid jobs, then wage acceleration is a welcome indicator of an equally welcome reallocation of labor towards more productive activities,” Sandbu writes.
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.
MIT researchers developed a new system to build gravity-defying spare parts in space that is currently being tested aboard the International Space Station, reports Rahul Rao for Popular Science. “The MIT group’s process involves taking a flexible silicone skin, shaped like the part it will eventually create, and filling it with a liquid resin,” writes Rao. “These are going to be our first results for a really novel process in microgravity,” explains Ariel Ekblaw SM ’17, PhD ’20, director of the Space Exploration Initiative.
Prof. Evelina Fedorenko speaks with Atlantic reporter Matteo Wong about her research exploring how “the brain behaves when an individual speaks different languages.” Fedorenko explains that “it seems like languages provide us with mappings between forms and meanings.”
