Researchers from MIT and elsewhere have found that a sequence of rocks from the Usua Supracrustal Belt in Greenland contain “an ironclad record of the early Earth’s magnetic field,” reports Keith Cooper for Space.com. “The new results from the Greenland rocks are considered more reliable because, for the first time, they are based on entire iron-bearing rocks (rather than individual mineral crystals) to derive the primordial field strength,” explains Cooper. “Therefore, the sample offers the first solid measure of not only the strength of Earth's ancient magnetic field, but also of the timing of when the magnetic field originally appeared.”

Prof. Christopher Knittel speaks with The Hill reporters Rachel Frazin and Zack Budryk about the implications of the latest climate rule put in place to mitigate power plant emissions. “What we’ve seen, even without these rules, is that coal generation is failing,” says Knittel. “These new rules will certainly push to speed that transition up.”

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 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 “discovered hitherto unknown space molecule while investigating a relatively nearby region of intense star birth,” reports Robert Lea for Space.com. This discovery “revealed the presence of a complex molecule known as 2-methoxyethanol, which had never been seen before in the natural world, though its properties had been simulated in labs on Earth,” writes Lea.

Writing for Forbes, Prof. Christian Catalini makes the case that when it comes to today’s digital infrastructure, from AI and robotics to financial services and digital marketplaces, “if the United States wants to continue to lead, it needs to create the right conditions for competition to thrive. Like in the early days of the internet, this starts with policymakers embracing and nurturing a novel architecture based on open protocols.” 

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.

GiveDirectly, a nonprofit co-founded by MIT and Harvard alumni, works with “economists to identify the most efficient ways to reduce poverty,” reports Katharine Houreld for The Washington Post. “Lump sums are the most efficient way to give cash, according to a study of GiveDirectly programs released in December that compared the impact of three methods,” explains Houreld. “Two years in, recipients of the lump sum have spent more money on health care, and more of their children have scored better on school exams, according to the study by MIT economics professor Abhijit Banerjee and others." 

Prof. Jonathan Gruber speaks with Boston Public Radio hosts Jim Braude and Margery Eagan to explain the relationship between inflation and interest rates. “What’s driving the inflation recently is auto insurance prices,” says Gruber. “Why are insurance prices going up? It actually comes back to the Fed. Auto insurers make a profit in two ways. One is by charging you more than they’ll pay out and the other is investing money and getting rates of return on that money.”

Robert Stoner, interim director of the MIT Energy Initiative, speaks with Boston Public Radio hosts Jim Braude and Margery Eagan about how the Bipartisan Infrastructure Act provides funding for hydrogen hubs around the country to create networks of hydrogen fuel producers. “We're going to use hydrogen as a substitute for natural gas. In order for that to happen, we have to get the cost way down,” Stoner explains.
