Good Owners-dogGPT, a chatbot guide designed for dog parents that wasco-founded by alumni Darin Bellisario PhD ‘15 and Raja Rajcic ’20, is featured by The Boston Globe’s Marcela García. “What happens today when [dog owners] go looking for information? They go to Google,” says Bellisario. “You find dozens of videos and blog posts and articles that are either contradictory or outdated or inaccurate, or whatever the algorithm or the ranking wants to show you.” 

MIT researchers have discovered that peptides can remain stable and form into, reports Earth.com’s Eric Ralls. “First, we were astounded that peptides remain stable at all in concentrated sulfuric acid, for many weeks on end,” says Prof. Mei Hong, an author on the study. “Even more remarkable was that they adopt specific three-dimensional structures instead of random shapes.” 

MIT researchers have discovered that peptides “not only survive in highly concentrated sulfuric acid but take on stable 3D conformations too,” writes Chemical & Engineering News’ Fionna Samuels. “The project started with a new collaboration between [Prof. Sara] Seager and the MIT chemist [Prof.] Mei Hong,” notes Samuels. “In the years since finding phosphine signals in Venusian clouds, Seager had been working her way through the building blocks of life—nucleic acids, amino acids, and lipids—to see if any survived concentrated acid exposure.”  

Prof. Susan Solomon joins Cleo Abram’s “HUGE* If True,” to discuss her 1985 research uncovering how chlorofluorocarbons, were depleting the ozone layer, which led to the Montreal Protocol that banned the use of those chemicals. “It was an interesting feeling being under the ozone hole, knowing that half a world away an incredible change [the Montreal Protocol] had just occurred that really had a lot of potential to change things in the future—and indeed it did,” says Solomon.  

MIT researchers have developed a low temperature process to extract battery-grade lithium from spodumene, the most common type of mineral containing lithium, using a reusable liquid reagent, writes Electronic Design’s Lee Goldberg. “The new process uses a liquid reagent to dissolve the rock into the useful forms of its constituent parts — not just battery-ready lithium salts, but also smelter-grade alumina and cement-ready silica,” writes Goldberg. “After the minerals are extracted, the solvent and reagent can be recovered and used again so that waste levels approach zero.”  

Prof. Brett McGuire joins Peter O'Dowd, host of WBUR’s “Here & Now,” to discuss astronomers’ discovery of Erythrulose, the sugar found in raspberries, in clouds of gas about 25,000 light-years away from Earth. “By a chemist's formal definition this is a sugar—given its structure, the way its atoms are bonded together,” says McGuire. "It’s not the sort of sugar that we think of as involved in making things sweet for us. But it is still a sugar in that it is a compound that stores energy and is involved in biological processes that access that energy and allow it to be used by living organisms." 

A study by MIT researchers has found evidence that the first signs of ozone depletion appeared in 1957 in the upper tropical stratosphere, driven by carbon tetrachloride, an industrial chemical introduced in the 1930s and widely used as a dry-cleaning and degreasing agent, writes Gizmodo reporter Ellyn Lapointe. “This finding underscores the importance of long-term atmospheric monitoring so that we can fully understand how it responds to chemical pollution,” Lapointe notes.

MIT engineers have developed a new low-temperature process for extracting battery-grade lithium from hard rock, while also reducing waste, reports Gayoung Lee for Gizmodo. “Mining is essential to technology and therefore to society, yet it is perceived negatively by much of the public as a destructive, polluting industry, in some cases with good reason,” explains Prof. Yet-Ming Chiang. “We hope to help change that perception by showing that there are cleaner, more sustainable ways to do it.”

Forbes contributor Michael T. Nietzel spotlights the 120 new members and 25 international members elected by the National Academy of Sciences for 2026. Several MIT faculty members – including Professors Michale Fee, Gareth McKinley, Keith Nelson, Bengt Holmstrom and Catherine Wolfram – were selected. 

Prof. Susan Solomon joins Rachel Feltman on Scientific American’s Science Quickly podcast to discuss her experience researching the cause and solution for the Antarctic ozone hole in the 1980s. “Amazingly, we can show, with 95 percent confidence, now the Antarctic ozone hole is beginning to heal,” says Solomon, who published a paper on that topic last year. “That was a real incredible moment for me…I was there in 1986, and in 2026 I saw this paper appear that actually shows that we can be confident we’re seeing recovery.”

According to the 2026 QS World University Rankings, MIT has been earned a No. 1 global ranking in 12 subject areas, including chemical engineering; chemistry; civil and structural engineering; computer science and information systems; data science and artificial intelligence; electrical and electronic engineering; engineering and technology; linguistics; materials science; mechanical, aeronautical, and manufacturing engineering; mathematics; and physics and astronomy, reports Michael T. Nietzel for Forbes.

New York Times reporter Rebecca Elliott spotlights Phoenix Tailings, a startup co-founded by MIT alumni that is developing a sustainable process for refining rare-earth refining in the United States. Elliott notes that Phoenix Tailings created a closed-loop design for their manufacturing method that “distinguishes this process from the more energy-intensive techniques used in China, where workers scoop up molten metal with ladles.”

MIT is “taking a quantum leap with the launch of the new MIT Quantum Initiative (QMIT), reports State House News reporter Katie Castellani. “There isn't a more important technological field right now than quantum with its enormous potential for impact on both fundamental research and practical problems,” said President Sally Kornbluth during the launch event. “QMIT will help us to ask the right questions, identify the most critical problems and create a roadmap for developing quantum solutions that are both transformative and accessible.” 

Writing for Physics Today, Prof. Yang Shao-Horn, Research Scientist Sokseiha Muy and their colleagues explain the limitations and concerns surrounding lithium-ion battery technology while highlighting the potential of solid-state batteries as an alternative. “Although solid electrolytes can significantly boost a battery’s energy density by minimizing the battery’s volume, the greatest gains come from replacing conventional graphite anodes with higher-capacity, low-electric-potential alternatives,” they write. 

MIT researchers have developed a new AI tool, dubbed “DrugReflector,” aimed at speeding up the drug discovery process, reports William A. Haseltine for Forbes. The researchers used DrugReflector to test tested almost 9,600 drugs in different human cell types.“This system was 17 times more accurate than older computational methods and improved as it used honest lab feedback,” writes Haseltine.
