Researchers at MIT have discovered the composition of primordial black holes, “potentially discovering an entirely new type of exotic black hole in the process,” reports Jacopo Prisco for CNN. “We were making use of Stephen Hawking’s famous calculations about black holes, especially his important result about the radiation that black holes emit,” says Prof. David Kaiser. “These exotic black holes emerge from trying to address the dark matter problem — they are a byproduct of explaining dark matter.”

MIT researchers have created an amber-like material that preserves DNA so it can store data, improving on current methods that use particles of silica or require freezing, reports Pandora Dewan for Newsweek. The team “demonstrated their material by embedding and subsequently removing a DNA sequence encoding the music for the Jurassic Park theme song,” Dewan explains. “Following this process, they sequenced the molecule and confirmed that no errors had been introduced into the DNA sequence.”

Researchers at MIT have “analyzed how primordial black holes with a trait known as color charge could have formed in the soup of particles that composed the early universe,” reports Leah Crane for New Scientist. “They’re not really colors,” explains Prof. David Kaiser. “If we zoomed in with a microscope we wouldn’t see colors with our eyes, but it’s a way of accounting for the fact that nature seems to only allow color-neutral combinations.” 

MIT scientists have discovered that metals become harder when heated under certain conditions, reports Isabelle Dume for Physics World.  In an interview, Prof. Christopher Schuch says by bombarding metals with tiny bits of sapphire small enough to avoid shock waves, “the result is a clean and quantitative set of data that clearly reveals the counterintuitive ‘hotter-is-stronger’ effect.”

Researchers at MIT have found that prospective job applicants who utilized basic AI modules in their application process were, on average, more likely to get hired and receive higher wages, reports Maria Gracia Santillana Linares for Forbes. “[Applicants] with access to the technology are more likely to get hired without any negative implications [from] employers,” says graduate student Emma Wiles.

MIT researchers used tools of computational complexity and mathematical concepts to prove that no analysis of the Super Mario Bros video game level “can say for sure whether or not it can ever be completed,” reports Matthew Sparkes for New Scientist. “The idea is that you’ll be able to solve this Mario level only if this particular computation will terminate, and we know that there’s no way to determine that, and so there’s no way to determine whether you can solve the level,” says Prof. Erik Demaine. 

Writing for the Boston Globe, graduate student Sophie Hartley spotlights researchers and arborists battling beech leaf disease  a highly infectious disease caused by microscopic roundworms that “can disrupt a tree’s ability to photosynthesize and therefore survive." “Over the past decade, federal, state, and private agencies have shown up en masse to learn all they can about beech leaf disease, resulting in an extensive body of knowledge to inform policy,” explains Hartley. “By matching the worms’ seemingly unstoppable push with equally relentless research, experimentation, and community support, the hope is that all is not lost. Not yet.” 

The MIT Haystack Observatory held its first open house since the Covid-19 pandemic, during which the general public was invited into the facility and offered a hands-on look at the work observatory scientists are conducting to investigate complex questions about our universe," writes Ava Berger for The Boston Globe. “It’s fascinating what is going on not that far away from where you were living your daily life,” said Sarah Erwin, an open house attendee. “People are actually grappling with what is happening in the universe.” 

Prof. Bob Langer and Prof. Giovanni Traverso have co-founded Syntis Bio, a biotech company that will use technology to “coat the stomach and potentially other organ surfaces, [change] the way that drugs are absorbed or, in the case of obesity, which hormones are triggered,” reports Allison DeAngelis for STAT. 

Prof. Netta Engelhardt talks to New Scientist’s Thomas Lawton about the possibility of singularities existing outside black holes. Theorists can now probe singularities from a deeper perspective, using insights into the possible quantum foundations of gravity. This new approach “flips the script” on how we think about singularities, says Engelhardt.

New York Times columnist Thomas Edsall spotlights recent research by Profs. Daron Acemoglu, David Autor and Simon Johnson, in which they explore whether artificial intelligence could be a beneficial tool for workers. “It is quite possible to leverage generative AI as an informational tool that enables various different types of workers to get better at their jobs and perform more complex tasks,” explains Acemoglu. However, he notes “to turn generative AI pro-worker, we need a major course correction.”

Researchers from MIT have discovered that integrating “Texas’ self-contained electrical grid with the broader national grid could prevent mass power outages,” reports Zack Budryk for The Hill. The researchers “modeled the effects of a bill introduced by Reps. Greg Casar (D-Texas) and Alexandria Ocasio-Cortez (D-N.Y.) that would connect the Electric Reliability Council of Texas (ERCOT) to the rest of the country,” explains Budryk. “They determined that if such a law had been enacted ahead of the 2021 event, Winter Storm Uri, up to 80 percent of the millions of blackouts caused by the storm could have been averted.”

Researchers from the MIT Climate Policy Center have shown increasing shared transmission reduces outage risk, writes Sara Dinatale for the Star-Telegram. The researchers found connecting the Texas power grid to neighboring systems could have reduced blackouts during Winter Storm Uri in 2021. “What we're trying to do is provide policymakers with data," explains Prof. Christopher Knittel. “We just want policymakers to know what the trade-offs are from interconnecting or not interconnecting. And hopefully they can make a better decision.” 

Reporting in Portuguese, Correio Braziliense highlights researchers at MIT who have developed a new technique that uses light stimuli to benefit people with paralysis or amputations. “Our work could help bring the use of optogenetics closer to humans in the realm of neuroprosthetics that control paralyzed muscles and other functions of the peripheral nervous system,” says graduate student Guillermo Herrera-Arcos. 

Boston Globe reporter Hiawatha Bray profiles Merlin, a startup aviation company working with researchers from MIT’s Lincoln Lab, the Federal Aviation Administration, and the US Air Force to test systems that could be used to help control a plane’s speed, altitude, and direction of flight. “Merlin has begun working with MIT’s Lincoln Lab to deploy technology that would let planes automatically avoid midair collisions,” Bray explains.
