The Economist highlights several studies by MIT researchers on income inequality and wages in the U.S., noting that “Clem Aeppli of Harvard and Nathan Wilmers of MIT found that earnings inequality basically reached a plateau after 2012.” Additionally, Prof. David Autor and his colleagues have found that wages for the bottom half of workers have been growing roughly two percentage points faster than for the upper half of workers.
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.”
Prof. Joshua Tenenbaum speaks with Wired reporter Will Knight about AI image generators and the limitations of AI tools. “It's amazing what they can do,” says Tenenbaum, “but their ability to imagine what the world might be like from simple descriptions is often very limited and counterintuitive.”
Graduate student Matthew Groh discusses Detect Fakes, a research project he co-created aimed at teaching people how to detect deepfakes, with Wall Street Journal reporter Ann-Marie Alcántara. Groh recommends people pay attention to the context of an image or video, noting that people can “pay attention to incentives and what someone is saying and why someone might be saying this.”
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.
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.
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.
