Researchers from MIT and elsewhere published a paper exploring the abilities of language models and how they differ from those of humans, reports Will Knight for Wired. Prof. Josh Tenenbaum says “GPT-4 is remarkable but quite different from human intelligence in a number of ways,” writes Knight. “It lacks the kind of motivation that is crucial to the human mind.”
Researchers at the McGovern and Broad Institutes have developed a bacterial "nanosyringe" that can inject large proteins into specific cells in the body, which could lead to safer and more effective treatments for a variety of conditions, including cancer, reports Michael Le Page for New Scientist. “The fact that this can load a diversity of different payloads of different sizes makes it unique amongst protein delivery devices,” says graduate student Joseph Kreitz.
Ingrid Wickelgren at Scientific American highlights a new study from researchers at the McGovern and Broad Institutes, in which they used a bacterial ‘nanosyringe’ to inject large proteins into human cells. “The syringe technology also holds promise for treating cancer because it can be engineered to attach to receptors on certain cancer cells,” writes Wickelgren.
IEEE Pulse reporter Leslie Mertz spotlights Prof. Ed Boyden’s work on refining expansion microscopy. “My hope for expansion, looking 5 or 10 years out, is that it could help produce a map of molecules that is detailed enough to help us understand life itself,” says Boyden.
Prof. Li-Huei Tsai and Prof. Ed Boyden co-founded Cognito Therapeutics after their research found that gamma waves could help clear amyloid plaques, which are known to appear in Alzheimer’s patients, reports Ryan Cross for The Boston Globe. “It was the most surprising result I’ve ever got in my life,” says Tsai. “When we published our first paper, most people said, ‘I don’t believe it. This is too good to be true. How can something this simple have this kind of effect?’”
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.”
