A new paper by Prof. Admir Masic and his colleagues reinforces his theory that the ancient Romans used a technique called “hot-mixing” to create concrete, reports Andrew Paul for Popular Science. “The evidence resides at an ancient Roman construction site preserved in great detail by the Mount Vesuvius eruption,” explains Paul. “Isotopic analysis confirmed that the workers in Pompeii relied on hot-mixing when making their concrete.”
Visiting Scientist Judah Cohen speaks with USA Today reporter Doyle Rice about how the polar vortex could send a blast over cold air to areas of the central and eastern United States. “I believe that the entire cycle of a weak or disrupted polar vortex that began at the end of November is coming to its conclusion by the end of next week,” explains Cohen. “Clearly, the polar vortex is strengthening and some period of milder weather in the central and eastern U.S. looks inevitable to me.”
President Sally Kornbluth is honored by The Boston Globe as one of the Bostonians of the Year, a list that spotlights individuals across the region who, in choosing the difficult path, “showed us what strength looks like.” Kornbluth was recognized for her work being of the “most prominent voices rallying to protect academic freedom.”
While analyzing samples from a newly-discovered construction site in Pompeii, researchers at MIT confirmed the ingredients and methods behind the ancient Romans’ durable and self-healing concrete, reports Will Dunham for Reuters. "Modern concretes generally lack intrinsic self-healing capability, which is increasingly important as we seek longer-lasting, lower-maintenance infrastructure," explains Prof. Admir Masic. "While the ancient process itself is not a direct replacement for modern standards, the principles revealed can inform the design of next-generation durable, low-carbon concretes."
A new report co-authored by Prof. Dava Newman and Lindy Elkins-Tanton '87, SM '87, PhD '02 explores the highest-priority science objectives for the first human missions to Mars, reports Eric Berger for Ars Technica. “We’re searching for life on Mars. The answer to the question ‘are we alone’ is always going to be ‘maybe,’ unless it becomes yes,” explains Newman.
Prof. Carlo Ratti speaks with Reuters reporter Catherine Early about the growing number of initiatives aimed at creating more walkable neighborhoods in urban cities. “Small, tangible changes – like pedestrianizing a block, repainting a square, or hosting a street festival – help people understand what proximity feels like in practice,” Ratti explains. “When people are involved in shaping their environment, skepticism often turns into ownership.”
Researchers at MIT have developed a device that can measure blood glucose levels through the skin. The team used “Raman spectroscopy to measure blood glucose because of the method’s ability to identify the chemical composition of samples noninvasively,” writes Sneha Khedkar for The Scientist. “The approach involves shining monochromatic light on samples and analyzing how the light scatters.”
In an opinion piece appearing in Wired, Prof. Elfatih Eltahir and postdoctoral researcher Yeon-Woo Choi examine the “ongoing water scarcity crisis” in Tehran. “With dry soils and high evaporation, rivers and wetlands shrank. Falling reservoir levels led to disruptions in hydropower generation, and water shortages prompted strict saving measures across parts of the capital,” they write. “These cascading impacts exposed how vulnerable Tehran’s infrastructure, economy, and communities have become under compounding heat and drought stress.”
A 1927 argument between Albert Einstein and Niels Bohr regarding “one of the core mysteries of quantum physics,” has led multiple scientists, including Prof. Wolfgang Ketterle, to conduct the thought experiments the two scientists developed a century ago to determine if “light [is] really a wave, a particle or a complex mixture of the two,” writes Karmela Padavic-Callaghan for New Scientist.
Addis Energy, a startup co-founded by Prof. Yet-Ming Chiang is using the earth “as a chemical reactor to make ammonia in a cleaner way,” reports Alex Knapp for Forbes. The team identifies “rocky formations underground with large amounts of iron,” explains Knapp. “Then they inject those rocks with water, nitrogen and a chemical catalyst. That causes the oxygen in the water to bind with the iron in the rocks—making rust—freeing the hydrogen, which reacts with nitrogen to form ammonia.”
A new study by MIT researchers has found that “AI chatbots were surprisingly effective at convincing people to vote for a particular candidate or change their support for a particular issue,” reports Alex Wilkins for New Scientist. “Even for attitudes about presidential candidates, which are thought to be these very hard-to-move and solidified attitudes, the conversations with these models can have much bigger effects than you would expect based on previous work,” says Visiting Prof. David Rand.
Prof. Karrie Karahalios has been named to Fast Company’s 2025 “AI 20” list for her work empowering individuals and communities to take a stand against algorithmic overreach, reports Mark Sullivan for Fast Company. “As we build these systems, and they seem to be permeating our society right now, one of my big goals is not to ignore human intuition and not to have people give up agency,” says Karahalios.
Researchers at MIT and elsewhere “examined how popular chatbots could change voters’ minds about candidates in the United States, Canada and Poland,” reports Will Oremus for The Washington Post.
Fortune reporter Orianna Rosa Royle spotlights Luana Lopes Lara '18, co-founder of Kalshi, a company that allows users to bet on the outcome of events, such as “elections, sports matches, and pop culture happenings.” Rosa Royle details Lopes Lara’s journey establishing Kalshi with her co-founder Tarek Mansour ’18, MNG ’19.
Fox Business host Stuart Varney spotlights MIT’s new Artificial Intelligence and Decision Making (AI+D) major, which has quickly become, “the second most popular undergrad major at MIT.”
