Prof. Tom Leighton, CEO of Akamai, speaks to Fast Company reporter Victor Dey about his vision for a faster and cheaper AI grid that could serve as an alternative to large data centers, and more effectively route inference workloads. “Many inference tasks do not need the largest model or the largest cluster or the most expensive compute,” says Leighton. “What they need is the ability to marry the right model, in the right place, data and moment, at the most effective cost.” 

By studying ‘smears’ in fast radio bursts, fleeting flashes of radiation, MIT researchers discovered diffuse clouds of baryonic gas may contain the missing ordinary matter in the universe, writes Gizmodo’s Gayoung Lee. “These diffuse clouds may be flung outside galaxies through black hole jets,” Lee explains. 

Prof. Sebastian Lourido speaks to Boston Globe reporter Lindsay Crudele about the safety of local produce amidst the current cyclospora outbreak. “There are many features of local agriculture that are less susceptible to the spread of these kinds of diseases,” says Lourido. 

The life and work of the late Nobel laureate Prof. Susumu Tonegawa, founding director of MIT’s Picower Institute for Learning and Memory, is spotlighted by The New York Times’ Dylan Loeb McClain. “Few scientists have reshaped our understanding of biology as profoundly,” says Prof. Myriam Heiman, director of the Picower Institute. “His intellectual fearlessness, extraordinary creativity and relentless pursuit of fundamental questions opened entirely new frontiers in both immunology and neuroscience.” 

A new study by MIT researchers finds high-fat, low-carbohydrate ketogenic diets may increase the risk of certain intestinal cancers, writes Newsweek’s Daniella Gray. “The researchers say future studies will be needed to better understand how specific dietary fats influence cancer risk and whether modifying the composition of ketogenic diets could reduce potential harms while preserving any health benefits,” writes Gray.  

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." 

MIT researchers found that the keto diet, which emphasizes low carbs and sugar, could increase the risk of tumors in the small intestine, explains New York Post reporter Allie Yang. The researchers found that “cells burning fat (from ketosis) start a chain reaction which leads to stem cells multiplying rapidly, increasing the chance they go out of control and become cancer,” Yang explains.  

The Guardian’s David Kohn points to a study by Prof. Siniša Hrvatin that proposes targeting the preoptic area of the brain to induce torpor (a hibernation-like state) as a solution for astronauts to survive long term space travel. “Key aspects of the circuit appear to be conserved across different animals,” says Hrvatin. “I think we can use it to modify metabolism.” 

GBH Curiosity Desk host Edgar B. Herwick III comes to MIT for a scoop of science, daring Prof. Pablo Jarillo-Herrero to embark on a twisty challenge: describing his work in the field of twistronics in the amount of time it takes to eat a soft serve outside the Eastern Edge Food Hall. “We were just curious,” says Jarillo-Herrero of the inspiration for his work. “We have never been able to change the angle between materials. Whenever you explore or look at something where you’ve never been able to do it, interesting things are going to happen.” 

After analyzing data from the LIGO, Virgo and KAGRA gravitational wave detectors, MIT researchers have found that 14% of black holes may be second-generation, formed by the merger of two smaller black holes, writes Gayoung Lee for Gizmodo. The scientists “created an analytic model to capture the kind of wobble that would have emerged from second-generation black holes. Around 14% of merging black holes followed this pattern, and the second-generation black holes identified had a very specific range of masses, at around 20 solar masses or 40 solar masses and above,” Lee explains.  

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 researchers have found that colon cancer cells can “change their identity, allowing them to travel through the body and form new tumors,” reports Daniella Gray for Newsweek. The findings could point to future treatments that can prevent metastasis—the leading cause of death for colorectal cancer patients, Gray explains. 

For Axios Boston, reporter Steph Solis highlights “Anita,” a solar-electric boat created by alumnus James Worden ‘89 that is due to launch this year. The boat was previewed at the 80th anniversary Charles River sail-a-thon. “The prototype, named ‘Anita’ after Worden's late wife, moves silently with no fumes or exhaust and uses LiFePO4 battery cells with a battery management system (it lets you charge the batteries while they're in use),” writes Solis. 

Prof. David Kaiser joins GBH “Particles of Thought” podcast host Dr. Hakeem Oluseyi to discuss his hunt for primordial black holes. “It’s a lot easier to find stuff coming off of a very bright, hot source, than a cold, dim one. So, the Hawking temperature of a black hole that has the same mass as our sun, or a little bigger would be so cold we would literally never be able to measure [its] radiation,” says Kaiser. “You’ll never see it [Hawking Radiation] from stellar collapse black holes, you’ll never see it from supermassive black holes, or even colder. The only hope to ever see it would be a smaller mass black hole.”

For Scientific American’s special section “The Young American Scientists,” Prof. Feng Zhang speaks with Tara Haelle about the importance of investing in science and education, noting that “American science has long been the strongest engine of discovery and innovation in the world.” Zhang shares: “I’m fortunate to work with extraordinary students and postdocs, but the infrastructure that lets them do their best work is under real stress: funding instability..., immigration uncertainty for international scientists and an erosion of public trust in expertise. We can lose the lead rapidly if we do not protect our innovation ecosystem.”
