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.”
Prof. Daron Acemoglu speaks with Financial Times reporters Claire Jones and Melissa Heikkilä about the economic implications of the AI boom. “There is a lot of pressure on managers to do something with AI… and there is the hype that is contributing to it,” says Acemoglu. “But not many people are doing anything super creative with it yet.”
A new study by MIT researchers suggests sea sponges may have been the “first animals to inhabit the Earth,” reports Maria Azzura Volpe for Newsweek. “In their work, the researchers linked so-called ‘chemical fossils’ found in ancient rocks to the ancestors of a class of modern-day sea sponges known as demosponges,” explains Volpe. “These chemical fossils—the molecular remnants of once-living organisms that have been buried, transformed, and preserved in sediment over time—were discovered in rocks that date back to more than 541 million years ago, during the Ediacaran Period.”
MIT researchers have uncovered new evidence that suggests some of Earth’s first living creatures are ancestors of the modern sea sponge, reports Andrew Paul for Popular Science. The researchers identified 541 million-year-old chemical fossils embedded in sediment that they believe may indicate that some of Earth’s earliest creatures were the ancient relatives of today’s sea sponges.
George Smoot '66, PhD '70, a recipient of the 2006 Nobel Prize in Physics for his work “finding the background radiation that finally pinned down the Big Bang Theory,” has died at age 80, reports the Associated Press.
In an effort to better understand how protein language models (PLMs) think and better judge their reliability, MIT researchers applied a tool called sparse autoencoders, which can be used to make large language models more interpretable. The findings “may help scientists better understand how PLMs come to certain conclusions and increase researchers’ trust in them," writes Andrea Luis for The Scientist.
New Yorker reporter Julian Lucas spotlights Prof. Emeritus Tim Berners-Lee’s role in the creation of the world wide web and his current focus on online data protection and regulation. The creation of the web “took companies giving up their patent rights, it took individuals giving up their time and energy, it took bright people giving up their ideas for the sake of a common idea,” says Berners-Lee.
Writing for The Guardian, Prof. Emeritus Tim Berners-Lee describes his original concept for the world wide web as a platform for everyone, and his current efforts aimed at online data protection and regulation. “I gave the world wide web away for free because I thought that it would only work if it worked for everyone,” explains Berners-Lee. “Today, I believe that to be truer than ever. Regulation and global governance are technically feasible, but reliant on political willpower. If we are able to muster it, we have the chance to restore the web as a tool for collaboration, creativity and compassion across cultural borders. We can re-empower individuals, and take the web back. It’s not too late.”
Researchers at MIT have developed magnetic transistors, “which could enable faster and more energy-efficient semiconductors,” reports Alex Knapp for Forbes. “Researchers have been trying to use magnets this way for years, but the materials used so far haven’t been optimal for computing functions,” explains Knapp. “That changed after experimenting with chromium sulfur bromide, which replaces the silicon in a conventional microchip and enables the transistors to be switched on and off with an electric current.”
Prof. Pierre Azoulay speaks with WBUR’s Martha Bebinger about a new study examining the potential impact of NIH budget cuts on the development of new medicines. Azoulay and his colleagues found that “more than half of drugs approved by the FDA since 2000 used NIH-funded research that would likely not have happened if the NIH had operated with a 40% smaller budget,” Bebinger explains.
Fierce Biotech reporter Darren Incorvaia writes that a new study by MIT researchers demonstrates how potential NIH budget cuts could endanger the development of new medications. The researchers found that if the NIH budget had been 40% smaller from 1980 to 2007, the level of NIH cuts currently being proposed, “the science underlying numerous drugs approved in the 21st century would not have been funded,” Incorvaia explains. The findings suggest that “massive cuts of the kind that are being contemplated right now could endanger the intellectual foundations of the drugs of tomorrow,” explains Professor Pierre Azoulay.
