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.”
Kevin Hu SB ’13, SM ’15, PhD ’19 co-founded Metaplane, a startup aimed at providing users with data analytics-focused tools, reports Kyle Wiggers for TechCrunch. “Metaplane monitors data using anomaly detection models trained primarily on historical metadata. The monitors try to account for seasonality, trends and feedback from customers, Hu says, to minimize alert fatigue, “writes Wiggers.
Prof. Daron Acemoglu and his colleagues have found that “managers educated at business schools were more likely to favor shareholders over employees,” writes University of London Prof. André Spicer for the Financial Times. The researchers found that “employees working for companies run by a business school-educated manager earned, on average, 6 percent less in the US and 3 percent less in Denmark,” writes Spicer.
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.
Writing for the Daily News, Prof. Carlo Ratti and Harvard Prof. Edward Glaeser highlight a new report by the “New” New York Panel aimed at reimagining New York City. “This is the moment to embrace the ‘New’ New York Panel’s three-pronged approach of reducing the unnecessary regulations that limit entrepreneurship, investing in New York’s children and creating exciting, safe, walkable streetscapes,” Ratti and Glaeser write.
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.”
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.
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.
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.”
Prof. Alan Lightman hosts a new, three-part series titled “Searching, Our Quest for Meaning in the Age of Science,” reports Jane Levere for Forbes. Lightman “explores timeless and deep questions about man and the universe with ethicists, philosophers, faith leaders and Nobel Prize-winning scientists,” writes Levere.
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.”
Alex Westner SM ’98 founded Xander, a company that uses augmented reality in personalized glasses to provide real-time closed captions for people with hearing loss, reports Dalvin Brown for The Wall Street Journal. “The glasses have an embedded display on the right side, where text appears almost as quickly as it’s picked up by a built-in microphone,” writes Brown. “There’s no wireless connection – all processing happens within the glasses.”
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.
