Interesting Engineering reporter Rizwan Choudhury spotlights a new study by MIT researchers that finds light can cause evaporation of water from a surface without the need for heat. The photomolecular effect “presents exciting practical possibilities,” writes Choudhury. “Solar desalination systems and industrial drying processes are prime candidates for harnessing this effect. Since drying consumes significant industrial energy, optimizing this process using light holds immense promise.”

Writing for Project Syndicate, Institute Prof. Daron Acemoglu and Prof. Simon Johnson draw upon the work of economist David Ricardo and his insights on the Industrial Revolution to explore how to respond to the challenge posed by AI to good jobs. “It is still possible to have pro-worker AI, but only if we can change the direction of innovation in the tech industry and introduce new regulations and institutions,” they write.  

Writing for MIT Technology Review, Georgina Gustin chronicles the research journey of Polina Anikeeva, the MIT scientist and engineer who developed flexible brain probes to stimulate neurons and potentially treat neurological disorders. In 2017, Anikeeva became fascinated by the hypothesis that Parkinson’s might be linked to pathogens in the digestive system. Today she and her team use specialized devices to explore the brain-gut connection. “This is a new frontier,” Anikeeva says. 

MIT researchers have developed a machine-learning accelerator chip to make health-monitoring apps more secure, reports Aman Tripathi for Interesting Engineering. “The researchers subjected this new chip to intensive testing, simulating real-world hacking attempts, and the results were impressive,” explains Tripathi. “Even after millions of attempts, they were unable to recover any private information. In contrast, stealing data from an unprotected chip took only a few thousand samples.”

Researchers at MIT have developed a new measure called “outdoor days,” which describes the number of days per year in which temperatures are comfortable enough for outdoor activities in specific locations around the world, reports Lebawit Lily Girma for Bloomberg News. “Changes in the number of outdoor days will impact directly how people around the world feel climate change,” says Prof. Elfatih Eltahir.

Bloomberg Opinion columnist Parmy Olson spotlights a new study by MIT researchers that finds AI chatbots can be highly persuasive when reinforced with facts and could potentially be used to help tackle conspiracy theories. “The scientists invited more than 2,000 people who believed in different conspiracy theories to summarize their positions to a chatbot — powered by OpenAI’s latest publicly available language model — and briefly debate them with the bot,” Olson writes. “On average, participants subsequently described themselves as 20% less confident in the conspiracy theory; their views remained softened even two months later.” 

Prof. Esther Duflo will present her research on poverty reduction and her “proposal for a global minimum tax on billionaires and increased corporate levies to G-20 finance chiefs,” reports Andrew Rosati for Bloomberg. “The plan calls for redistributing the revenues to low- and middle-income nations to compensate for lives lost due to a warming planet,” writes Rosati. “It also adds to growing calls to raise taxes on the world’s wealthiest to help its most needy.”

MIT scientists have uncovered evidence that the different layers of the brain’s cortex generate different brain waves, reports Simon Makin for Scientific American. “The findings may have implications for understanding—and even treating—neuropsychiatric conditions,” Makin explains.

Prof. David Autor speaks with Nature reporter Dalmeet Singh Chawla about the long-term impact of his research on policy documents. Autor’s work from November 2003 “is now the third most cited in policy documents worldwide,” writes Chawla. “Autor thinks his study stands out because his paper was different from what other economists were writing at the time. It suggested that ‘middle-skill’ work, typically done in offices or factories by people who haven’t attended university, was going to be largely automated, leaving workers with either highly skilled jobs or manual work.”

Prof. Kieran Setiya speaks Sean Illing, host of Vox’s The Gray Area podcast, about how philosophy can be used as a tool when handling midlife crises. “There’s a real continuity between the literary and human description of phenomena like grief and philosophical reflection,” says Setiya. “Because often what philosophical reflection provides is less a proof that you should live this way and more concepts with which to articulate your experience and then structure and guide how you relate to reality. And seen that way, we can understand how philosophy can operate as self-help.”

Writing for The Wall Street Journal, Prof. S.P. Kothari and Senior Lecturer Robert Pozen explain why U.S. consumers “continue to feel they are suffering from inflation, although the annual rate of inflation dropped sharply during 2023.” “The answer is that consumers have a broader time horizon,” they write. “[Consumers] are looking at the rate of price increases over the past three years. From January 2021 to January 2024, the consumer price index for all items rose by 17.96%.”

Researchers at MIT have discovered that a previously witnessed supermassive black hole has “a smaller companion black hole zipping around it, kicking up dust every time it goes by,” reports John Wenz for Astronomy. This discovery “shakes up our thinking of what the environment at the core of the galaxy looks like,” explains Wenz. “Instead of a simple disk of matter surrounding the central black hole, steadily swirling across its event horizon, the centers of galaxies could host multiple black holes of different sizes, leading to more complex feeding behavior.”

Prof. Emeritus Olivier Blanchard speaks with New York Times reporter Peter Coy about the impact of wage increases on inflation. “Fundamentally, it is hard to believe that when the economy is overheating there is not going to be pressure of some sort on wages and prices,” says Blanchard.

MIT researchers have developed a new type of spring-like device that uses a flexible element to help power biohybrid robots, reports Brian Heater for TechCrunch. “The muscle fiber/flexure system can be applied to various kinds of robots in different sizes,” Heater writes, adding that the researchers are, “focused on creating extremely small robots that could one day operate inside the body to perform minimally invasive procedures.”

Researchers from MIT and elsewhere explored the effectiveness of climate commitments made by banks to mitigate the effects of climate change, reports Nicole Goodkind for CNN. “Our results cast doubt on the efficacy of voluntary climate commitments for reducing financed emissions, whether through divestment or engagement,” the researchers note.
