Researchers at MIT have discovered what makes ancient Roman concrete “exponentially more durable than modern concrete,” reports Jim Morrison for Wired. “Creating a modern equivalent that lasts longer than existing materials could reduce climate emissions and become a key component of resilient infrastructure,” writes Morrison.
MIT researchers have discovered that ancient Romans used calcium-rich mineral deposits to build durable infrastructure, reports Daniel Cusick for Scientific American. This “discovery could have implications for reducing carbon emissions and creating modern climate-resilient infrastructure,” writes Cusick.
Prof. Admir Masic speaks with NPR host Scott Simon about the concrete blend used by the ancient Romans to build long standing infrastructures. “We found that there are key ingredients in ancient Roman concrete that lead to a really outstanding functionality property in the ancient mortar, which is self-healing,” explains Masic.
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.”
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.
Prof. Diana Henderson, Prof. Daniel Jackson, Prof. David Kaiser, Prof. S.P Kothari, and Prof. Sanjay Sarma have released a new white paper “summarizing their ideas for a new type of undergraduate institution,” writes David Rosowsky for Forbes. “The authors have done a commendable job identifying and assembling some of the proven high-impact practices each of these types of higher educational institutions can offer,” writes Rosowsky.
Chancellor Melissa Nobles spoke at the launch of the Burnham-Nobles Digital Archive, a digital resource co-authored by Nobles and Northeastern Prof. Margaret Burnham aimed at identifying and documenting anti-Black killings in the mid-century South, reports Jessica Taylor Price for News @ Northeastern. “The archive seeks to right an egregious wrong in American history – the mass coverup of cases of lynching during the Jim Crow era," writes Price.
Prof. David Kaiser discussed the significance of Alain Aspect, John F. Clauser and Anton Zeilinger’s research conducting experiments concerning quantum entanglement, for which they were honored with the 2022 Nobel Prize in Physics. “Clauser got a lot of pushback from scientists who didn’t think this was even part of science,” said Kaiser. “He had to have a lot of stick-to-itiveness to publish his result.”
The new MIT Museum opens to the public this weekend in its new location in Kendall Square, which is “quite significant because this is the heart of innovation,” notes GBH’s Jared Bowen. Museum visitors will not only get a sense of MIT’s long history of innovation, but also get a sense of the scientific process, with exhibits featuring “part of the machinery that was used to help sequence the human genome, [and] the star shade petal that allowed NASA to photograph exoplanets,” Bowen explains.
Lecturer Mikael Jakobsson, Rosa Colón Guerra (a resident at MIT’s Visiting Artists program), and graduate student Aziria Rodríguez Arce have created a new board game, called Promesa, that more accurately reflects the reality of Puerto Rico’s history and people, reports Maria Parazo Rose for Popular Science. “The game is based on the real-life PROMESA act, which was established by the US government in 2016 in response to the island’s debt crisis, putting American lawmakers in charge of the country’s finances,” explains Rose. “To win, you must settle Puerto Rico’s bills and build up the country’s infrastructure, education, and social services.”
Prof. Craig Steven Wilder is a featured expert in a new documentary titled “Driving While Black: Race, Space and Mobility in America,” reports WBUR. “For me, the term ‘driving while black’ isn’t just a slogan, it isn’t just a part of our political rhetoric, it’s not just something we say to remind ourselves of the persistence of racism in the United States. It’s a very personal experience of remembering, in fact, the anxiety, the fear,” says Wilder.
