Prof. Earl K. Miller speaks with CBS News host Susan Spencer about multitasking, fear of laziness, and the importance of downtime. “A lot of time some of your best thoughts come to you when your conscious mind is out of the way, when you allow the unconscious thoughts to bubble up,” says Miller. “And sometimes it’s good to be lazy – not lazy, but to tune out a bit and let these thoughts bubble up.”
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.
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.”
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. Roger Levy, Prof. Tracy Slatyer and Prof. Martin Wainwright are among the 2024 John Simon Guggenheim Foundation Fellowship recipients, reports Michael T. Nietzel for Forbes. “The new fellows represent 52 scholarly disciplines and artistic fields and are affiliated with 84 academic institutions,” writes Nietzel.
Prof. Roger Levy, Prof. Tracy Slatyer and Prof. Martin Wainwright have been awarded John Simon Guggenheim Foundation Fellowships, reports Mark Feeney for The Boston Globe. A Guggenheim fellowship “is one of the most sought-after honors in academe, the arts, and culture,” explains Feeney. “It helps underwrite a proposed art or scholarly project.”
Prof. Tali Sharot speaks with Washington Post reporter Kristyn Kusek Lewis about how to spark happiness and embrace novelty. “The neurons in our brains stop responding to things that don’t change,” says Sharot. “We need to make room for the new and unexpected, so our brain filters out the old and expected. We’ve all experienced this physically when jumping in a pool: The water feels cold at first, but then your body acclimates. In the case of a negative emotion, like grief, it’s good that we habituate, because the feelings lessen over time. But when it comes to positive things, we actually enjoy them less as we get used to them.”
Writing for The Next Big Idea Club, Prof. Tali Sharot and Harvard Law School Professor Cass Sunstein cite their new book “Look Again: The Power of Noticing What Was Always There,” to share five insights on how to incorporate more joy into life. “If you need to complete an unpleasant task (household chores, administrative work) complete them in one go,” they write. “Habituation will help you motor through the yukky bits of life, making them feel less unpleasant. Swallow the bad whole but insert short breaks into pleasant experiences to increase pleasure.”
Research Scientist Robert Ajemian, graduate student Greta Tuckute and MIT Museum Exhibit Content and Experience Developer Lindsay Bartholomew appear on The Economist’s Babbage podcast to discuss the development of generative AI. “The way that current AI works, whether it is object recognition or large language models, it’s trained on tons and tons and tons of data and what it’s essentially doing is comparing something it’s seen before to something it’s seeing now,” says Ajemian.
Alumnus Benjamin Rapoport co-founded Precision Neuroscience, a brain-computer interface company, that is developing technology that will allow “paralyzed patients the ability to operate a computer with their thoughts,” reports Jo Craven McGinty for The Wall Street Journal. “In order to be a citizen of the world in 2024, to communicate with loved ones, to make a living, the ability to work with a digital system is indispensable,” says Rapoport. “To operate a word processor is totally transformative.”
Will Dunham at Reuters writes about new research from Prof. Evelina Fedorenko and others, which found that polyglots “who spoke between five and 54 languages” used less brain activity when processing their native language. "We think this is because when you process a language that you know well, you can engage the full suite of linguistic operations - the operations that the language system in your brain supports," says Fedorenko.
MIT scientists have found that a potential treatment for Alzheimer’s disease involving flickering lights and low-pitched sound could also help prevent cognitive problems after cancer treatment, reports Clare Wilson for New Scientist. The treatment is aimed at stimulating 40 Hz brainwaves, which are linked to memory processing. The results suggest targeting such “brainwaves may result in broader benefits for the brain, including increasing the activity of immune cells and, most recently, boosting its drainage system, which could help clear a toxic protein called beta-amyloid.”
Cognito Therapeutics, an MIT startup co-founded by Prof. Li-Huei Tsai and Prof. Ed Boyden, has developed a headset that uses light and sound to slow the cognitive decline in Alzheimer’s patients, reports Emily Mullin for Wired. “Cognito’s headset, dubbed Spectris, delivers flashing lights and sounds through a pair of connected glasses and headphones to stimulate gamma waves in the brain” writes Mullin. “Different types of brain waves have different paces, or frequencies. Gamma waves are fast-frequency brain waves associated with thinking skills and memory, and people with Alzheimer’s are known to have fewer of these fast brain waves.”
A new study by MIT researchers finds that an experimental Alzheimer’s treatment involving sound and light stimulation at a frequency of 40 Hz is associated with, “an increase in activity of the brain's own cleanup crew; the glymphatic system,” reports Pandora Dewan for Newsweek. The findings offer an, “exciting, non-invasive potential treatment option for patients with neurological disorders in the future,” Dewan notes.
MIT scientists have found that an experimental treatment for Alzheimer's disease involving sounds and flickering lights appears to “ramp up the brain’s waste disposal networks, which boosts the clearance of beta-amyloid and other toxic proteins that contribute to memory and concentration problems,” reports Clare Wilson for New Scientist. “Once we understand the mechanism, we can probably figure out how to further optimize this whole concept and improve the efficacy,” explains Prof. Li-Huei Tsai.
