In an excerpt from “Your Brain on Art” published in Fast Company, Susan Magsamen and Ivy Ross spotlight Prof. Li-Huei Tsai research exploring whether gamma oscillations from light and sound could help ease Alzheimer’s symptoms. “Li-Huei believes that increased gamma oscillations in the brain engage many different systems and cell types,” write Magsamen and Ross. “Because of this, the gamma waves may help with amyloid removal.”
Prof. Josh McDermott co-authored a study that explores how music and podcasts can impact a person’s mood, reports Charlotte Hu for Popular Science. “There’s this big cultural shift in the way that we consume music and other audio that really happened over the last decade,” says McDermott. “It’s just changed the way that people live and probably has a lot of important effects.”
Prof. Feng Zhang founded Aera Therapeutics, a startup working to deliver curative genetic medicine to hard-to-reach parts of the body, reports Ryan Cross for The Boston Globe. “If Aera’s approach works in people, it could broaden the reach of genetic therapies, which currently have limited clinical applications – partly because there aren’t enough methods for getting those medicines to hone in on the right cells,” writes Cross.
Boston Globe reporter Aaron Pressman spotlights several MIT startups that are using AI to generate 3-D environments. Common Sense Machines, an MIT startup, is “trying to enhance the creativity of its app by adding a bit of, well, common sense,” writes Pressman. “Human babies form an understanding of the world by developing abstract models. Common Sense Machines is trying to add similar models to its 3D world builder.”
Researchers at MIT have developed a drone that can be controlled using hand gestures, reports Mashable. “I think it’s important to think carefully about how machine learning and robotics can help people to have a higher quality of life and be more productive,” says postdoc Joseph DelPreto. “So we want to combine what robots do well and what people do well so that they can be more effective teams.”
Researchers from MIT and elsewhere have studied the mind of polyglots and uncovered how language-specific regions of the brain respond to different and familiar languages, reports Natalia Mesa for Science. The researchers found that “the activity in the brain’s language network fluctuated based on how well participants understood a language. The more familiar the language, the larger the response,” writes Mesa. “There was one exception to the rule: when participants heard their native tongue, their language networks were actually quieter than when they heard other familiar languages.”
Writing for CNBC, senior lecturer Tara Swart shares four tips to avoid brain fog and forgetfulness. “By articulating your goals to yourself out loud, you can start to be more intentional about changing your habits,” writes Swart. “And through that repetition, your brain and body will start to follow suit.”
National Geographic reporter Maya Wei-Haas explores how the ancient art of origami is being applied to fields such a robotics, medicine and space exploration. Wei-Haas notes that Prof. Daniela Rus and her team developed a robot that can fold to fit inside a pill capsule, while Prof. Erik Demaine has designed complex, curving fold patterns. “You get these really impressive 3D forms with very simple creasing,” says Demaine.
Researchers from MIT and Harvard have developed “a new type of electrically conductive hydrogel ‘scaffold’ that could eventually be used to create a soft brain-computer interface (or BCI) that translates neural signals from the brain into machine-readable instructions,” reports Adam Bluestein for Fast Company.
Prof. Joshua Tenenbaum speaks with Wired reporter Will Knight about AI image generators and the limitations of AI tools. “It's amazing what they can do,” says Tenenbaum, “but their ability to imagine what the world might be like from simple descriptions is often very limited and counterintuitive.”
Prof. Evelina Fedorenko speaks with Atlantic reporter Matteo Wong about her research exploring how “the brain behaves when an individual speaks different languages.” Fedorenko explains that “it seems like languages provide us with mappings between forms and meanings.”
Researchers at MIT have found that those with an E4 variant display abnormalities in cholesterol metabolism, reports William A. Haseltine for Forbes. “The MIT team suggest that the disruption of cholesterol metabolism could be a fundamental reason why those with the E4 variant are more likely to develop Alzheimer’s disease symptoms,” writes Haseltine.
MIT scientists have found that silent synapses - a type of memory-forming synapse - are present in the adult brain, reports The Economist. The discovery of these silent synapses, explains Prof. Mark Harnett, “is a lever for us to get into understanding learning in adults and how potentially we can get access to make it not degrade over the course of aging or disease.”
The Atlantic highlights a section of Prof. Alan Lightman’s forthcoming book, “The Transcendent Brain: Spirituality in the Age of Science.” Lightman writes, “I call myself a spiritual materialist. As a scientist, I’m a materialist. Not in the sense of seeking happiness in cars and nice clothes, but in the literal sense of the word: the belief that everything is made out of atoms and molecules, and nothing more. Further, I believe that the material stuff of the universe is governed by a small number of fundamental laws. Yet I have had transcendent experiences.”
An MIT research study suggests that those with the E4 variant of the APOE gene are more likely to develop Alzheimer’s symptoms, reports William A. Haseltine for Forbes. The variant “disrupts how fat molecules are processed in the brain,” writes Haseltine. “It appears that the disruption of these fat molecules could be the fundamental reason why those that contain the E4 variant are more likely to develop Alzheimer’s symptoms.”
