Prof. Paulo Lozano has received funding from NASA’s University SmallSat Technology Partnership (USTP) to “explore integration of tiny electronic thrusters – a propulsion system using electrical power to propel spacecraft – onto satellites, reports Robin Roenker for USA Today. “We have many ideas (for application),” says Lozano. “One is to send tens or even hundreds of these small satellites to the asteroid belt to help study and characterize the asteroids’ surface structures.”
Writing for Bloomberg, Prof. Carlo Ratti explores how street configuration and design can help reduce traffic speeds. “In studies we have conducted at our Senseable City Lab, we found that the posted speed limits often have little effect on how fast people drive,” writes Ratti. “Instead, the policies that work involve the design of the street itself.”
A new study by researchers at MIT suggests that “the biggest and most computationally intensive AI models may soon offer diminishing returns compared to smaller models,” reports Will Knight for Wired. “By mapping scaling laws against continued improvements in model efficiency, the researchers found that it could become harder to wring leaps in performance from giant models whereas efficiency gains could make models running on more modest hardware increasingly capable over the next decade.”
Graduate student Chung-Tao (Josh) Chou speaks with Tech Briefs reporter Andrew Corselli about his work developing a magnetic transistor that could lead to more energy-efficient circuits. “People have known about magnets for thousands of years, but there are very limited ways to incorporate magnetism into electronics,” says Chou. “We have shown a new way to efficiently utilize magnetism that opens up a lot of possibilities for future applications and research.”
Researchers at MIT have developed a new method that can predict how plasma will behave in a tokamak reactor given a set of initial conditions, reports Gayoung Lee for Gizmodo. The findings “may have lowered one of the major barriers to achieving large-scale nuclear fusion,” explains Lee.
Using molecular evidence buried in rocks, researchers at MIT suggest that some of the Earth’s first living creatures are ancestors of the modern sea sponge, reports Ashley Fike for Vice. “The discovery suggests the earliest animals were simple, filter-feeding organisms that slowly cleaned the seas while the rest of the evolution was still figuring itself out,” says Fike. “These early sponges likely had no skeletons, nerves, or eyes – just porous bodies that absorbed water and nutrients. Yet they paved the way for everything that came next, from insects to mammals to us.”
Researchers at MIT have developed electron-conducting carbon concrete, a new kind of cement “that can store and release electricity like batteries,” reports Matthew Burgos for Design Boom. “MIT’s concrete battery shows a future where the material can be embedded into roads or parking areas to charge electric vehicles directly, or for off-grid homes that do not need external power,” Burgos explains.
Researchers at MIT have studied how chatbots perceived the political environment leading up to the 2024 election and its impact on automatically generated election-related responses, reports Patrick Kulp for Tech Brew. The researchers “fed a dozen leading LLMs 12,000 election-related questions on a nearly daily basis, collecting more than 16 million total responses through the contest in November,” explains Kulp.
Writing for the Financial Times, Principal Research Scientist Florian Berg explores “reasons to be hopeful about the resilience of efforts to tackle environmental issues at the corporate level.” Berg explains: “When looking at reporting on carbon emissions, ESG data and money invested in sustainable investment strategies, we can see big increases in recent years.”
George Smoot '66, PhD '70, the 2006 recipient of the Nobel Prize in Physics, has died at the age of 80, reports Kasha Patel for The Washington Post. Smoot’s work “helped take an image of the universe in its infancy, providing strong support for the Big Bang theory and new insight into the origins of the cosmos,” writes Patel.
MIT researchers have developed a new model that illustrates the chemical mechanisms underlying lithium-ion batteries, reports Gayoung Lee for Gizmodo. The findings could “lead to faster, more efficient batteries for electric vehicles, portable electronics, and more.”
Prof. Jonathan Gruber speaks with Newsweek reporter Jasmine Laws about the rise of health insurance premiums in the United States. “States with very active management and lots of competition on the exchanges will see the lowest increases,” says Gruber.
Prof. Canan Dagdeviren speaks with Bloomberg Businessweek Daily reporters Carol Massar and Tim Stenovec about her work developing conformable ultrasound technology aimed at enabling earlier breast cancer detection. “This technology can be a part of your personal bra, and you can wear it and while drinking your coffee within seconds, it can tell you [about] any anomaly with pinpoint accuracy,” Dagdeviren explains.
Researchers at MIT’s Lincoln Laboratory are developing “automated electric vessels to map the ocean floor and improve search and rescue missions,” reports Ramen Cromwell for Chronicle. "Ship-based echo sounders cover wide areas but with poor resolution, while undersea vehicles have resolution but search too slowly," says Andrew March, an assistant group leader in MIT Lincoln Laboratory’s Advanced Undersea Systems and Technology Group. "It's called a moonshot. We know less about Earth’s seabed than the moon's surface."
Prof. Steve Leeb and graduate student Daniel Monagle speak with Tech Briefs reporter Edward Brown about their work “designing an energy management interface between an energy harvesting source and a sensor load that will give the best possible results.” Monagle notes that in the future they hope to make the system “smaller so that it can fit in tight places like inside a motor terminal box. But beyond that we want to take advantage of AI tools to design techniques for minimizing the energy used by the system.”
