While visiting a house that was under renovation when Mount Vesuvius erupted, MIT researchers were able to confirm the tools and ingredients used by ancient Romans to create long-lasting concrete, reports Humberto Basilio for Scientific American. “The hot mixing method creates fragmented, highly porous lime clasts within the mortar that allow calcium to easily travel through the material and recrystallize to fill cracks,” Basilio explains. “Understanding and mastering this “self-healing” technology will allow engineers to use the technique in modern construction.” 

Prof. Admir Masic and his colleagues have confirmed that ancient Romans utilized “hot-mixing,” a technique that combines quicklime with volcanic rock, volcanic ash, and water, to create concrete that has lasted for thousands of years, reports Margherita Bassi for Gizmodo. “The team also discovered weights and measurement tools, which they propose may have been used to maintain concrete pouring ratios and build straight, even walls,” writes Bassi. “In short, the site revealed the clearest evidence yet of the ancient Roman use of hot-mixing in concrete.” 

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.” 

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.” 

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.” 

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.” 

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. 

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. 

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. 

Researchers at MIT have developed a noninvasive, light-based blood-glucose monitoring system capable of replacing finger pricks and under-the-skin sensors used by patients with diabetes, reports Andrew Paul for Popular Science. The approach could “even fit on a device the size of a watch,” explains Paul. “Each measurement scan takes slightly more than 30 seconds to complete. The device also shows an accuracy comparable to two commercially available, wearable glucose monitors.” 

Prof. Kevin Chen and his colleagues have designed a tiny, insect-sized aerial microrobot that is “faster and more acrobatic than any of its predecessors,” reports Phie Jacobs for Science. The device, “which measures just 4 centimeters across and weighs less than a paperclip, flies almost five times faster and accelerates twice as quickly as existing microrobots,” explains Jacobs. “It can also execute sharp turns while enduring 160-centimeter-per-second wind gusts and—perhaps most impressively—can complete 10 consecutive somersaults in 11 seconds.” 

Luana Lopes Lara ’18 and Tarek Mansour ’18, MNG ’19 co-founded Kalshi, a company that allows “users to bet on the outcome of future events such as elections, sports games and pop culture happenings,” reports Alicia Park for Forbes. Lopes Lara chronicles her journey from her time on stage as a professional ballerina in Austria to her years as a student at MIT to her entrepreneurial ambitions.
