Prof. David Kaiser and graduate student Alexandra Klipfel speak with New York Times reporter Dennis Overbye about their theory that a neutrino detected zipping through the Mediterranean Sea in February 2023 may have come from an exploding primordial black hole. Kaiser and Klipfel "concluded that if primordial black holes were the explanation for long-sought dark matter, scientists should expect about 40 black-hole explosions to occur each year in every cubic light-year near the Milky Way,” Overbye notes. 

Prof. Salvatore Vitale and graduate student Jack Heinzel speak with Scientific American reporter K.R. Callaway about the LIGO-Virgo-KAGRA (LVK) Collaboration’s latest catalog of gravitational wave detections, which “more than doubles the number of gravitational-wave candidate events—and reveals unexpected complexities of merging black holes.” Says Heinzel: “We’re learning a lot of things that are qualitative and phenomenological from the catalog. Starting to see all these different structures emerge is pretty fascinating.”

Prof. Nergis Mavalvala, dean of the MIT School of Science, and Prof. Salvatore Vitale join Edgar B. Herwick III of GBH’s Curiosity Desk to discuss the science behind the Laser Interferometer Gravitational-wave Observatory (LIGO) and how close we are to unraveling the secrets of the early universe. LIGO has provided the ability to “observe the universe in ways that have never been done before,” says Mavalvala. 

Researchers at MIT have developed “mini livers” that “can be injected into the body to help take over the functions of a failing liver,” reports Ian Randall for Newsweek. “If realized clinically, the development could provide a lifeline for many of the more than 10,000 Americans with chronic liver disease currently waiting for a transplant,” writes Randall. 

A study by researchers at MIT has found that high levels of greenhouse gas emissions in the atmosphere is impacting the satellite orbits that typically force objects back to Earth, leading to an increased amount of space junk, reports Sachi Kitajima Mulkey for The New York Times. “[W]e’re losing this cleaning force that we rely on” says William Parker PhD '25. 

Graduate student Yi-Hsuan (Nemo) Hsiao and his colleagues have developed insect-sized robots to assist with artificial pollination as bee populations decline, reports Maria Simon Arboleas for Euractiv. “The tiny drones, lighter than a paperclip, can fly at speeds of up to two meters per second for more than 1,000 seconds, while performing complex maneuvers such as repeated backflips,” writes Arboleas.

Researchers at MIT have developed a wearable breast cancer ultrasound device that could be used to detect breast cancer earlier, reports Amerigo Allegretto for AuntMinnie.com. “The device can image as deep as 15 cm into breast tissue and can image the entire breast from two or three locations,” explains Allegretto. “The team described the technology as an end-to-end system ultrasound architecture consisting of a novel sparse array geometry and a codesigned data acquisition system.” 

Prof. Kevin Chen and his colleagues have developed a bee-like robot that can assist with farming practices, such as artificial pollination without damaging crops, reports Claire Turrell for Offrange. “Chen’s robot bee, which is tethered to a power source, is currently limited to flying between plastic flowers in the lab, but the robot engineer can see its potential,” explains Turrell. “Bees are doing great in terms of open-field farming,” says Chen. “But there is one potential type of pollination I think we can consider in the longer term, which is indoor farming,” 

Quanta Magazine reporter Jonathan O’Callaghan spotlights Prof. David Kaiser and graduate student Alexandra Klipfel, and their work searching for evidence of primordial black holes. “Very little mass gets radiated over the majority of the black hole’s lifetime,” explains Klipfel. “But then, right at the end, it emits a majority of its mass in a very rapid explosion. It heats up really, really quickly, a runaway process that ends in a big explosion of ultra-high-energy particles.”

Prof. Jonathan How and graduate student Yi-Hsuan (Nemo) Hsiao speak with Tech Briefs reporter Andrew Corselli about their latest work developing an aerial microrobot that is “agile enough complete 10 consecutive somersaults in 11 seconds, even when wind disturbances threatened to push it off course.” Hsiao explains that: “This work demonstrates that soft and microrobots, traditionally limited in speed, can now leverage advanced control algorithms to achieve agility approaching that of natural insects and larger robots, opening up new opportunities for multimodal locomotion.” 

In a roundup of the biggest tech breakthroughs of 2025, Forbes reporter Alex Knapp spotlights how MIT engineers developed magnetic transistors, a “discovery [that] could enable faster and more energy-efficient semiconductors.”

Researchers at MIT have developed a new physical model that can help “improve predictions of proton mobility across a wide range of metal oxides,” reports Ameya Paleja for Interesting Engineering. “This can help develop new materials and technologies powered by protons as charge carriers, rather than relying on lithium, which is widely used now,” explains Paleja. 

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.” 

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.” 

Researchers at MIT have developed “artificial tendons made from tough, flexible hydrogel,” reports Neetika Walter for Interesting Engineering. “These rubber band–like connectors dramatically boost the speed, strength, and durability of muscle-powered robots,” explains Walter.
