Bloomberg reporter Akshat Rathi spotlights Sublime Systems, an MIT startup developing new technology to produce low-carbon cement. “Sublime’s solution involves splitting the cement-making process into two steps,” explains Rathi. “The first step is to make calcium—the key element in limestone—in a form that’s ready to chemically react with silicon—the key element in sand. Sublime reduces energy use and carbon emissions in this step by avoiding limestone and using electricity, rather than coal-fired heat.”

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.

Using statistical modeling, MIT researchers have found that the energy needed to power a fleet of fully autonomous EVs could generate as much carbon emissions as all the world’s data centers combined, reports Andrew Paul for Popular Science.

Washington Post reporter Pranshu Verma writes that a new study by MIT researchers finds the “future energy required to run just the computers on a global fleet of autonomous vehicles could generate as much greenhouse gas emissions as all the data centers in the world today.” 

Forbes reporter Stuart Anderson highlights Noubar Afeyan PhD ’87, a member of the MIT Corporation, and Prof. Hari Balakrishnan as two immigrants who have developed innovative technologies and startups.

Natalia Rodriguez ’09 speaks with Diverse Issues in Higher Education reporter Pearl Stewart about her work as a biomedical engineer focused on community healthcare. “I work to bring health technologies from the lab to the people, and I also work to bring the needs, the priorities and the strengths of communities back to engineers so they know who they’re designing for,” Rodriguez explains. 

Deepak Dugar MBA ’13, PhD ’13 founded Visolis, a biomanufacturing company developing carbon-negative, high-performance materials, reports John Cumbers for Forbes. “We use biology to make platform molecules. And then we use chemistry to turn them into a lot of different products. Because of this unique combination, we have an advantage both in terms of market as well as cost of technology development,” says Dugar.

On a recent episode of “Shark Tank,” Amrita Saigal '10 scored a $250,000 investment in her company Kudos, which is focused on making disposable diapers from sustainable and natural materials, reports Megan Sauer for CNBC. Saigal, who also founded a company called Saathi that makes sanitary napkins from banana peel fibers, notes she was inspired by seeing “just how much plastic we were putting into sanitary napkins and diapers.” 

Research Scientist Mary Knapp’s proposal for a Great Observatory for Long Wavelengths (GO-LoW), a space-based observatory consisting of thousands of satellites that could study the magnetic fields of distant and rocky exoplanets, has been selected for NASA’s Innovative Advanced Concepts programs, writes George Dvorsky for Gizmodo.

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.

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.
