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. 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.”
Research affiliate Ramin Hasani speaks with Kimberly Adams of Marketplace about how he and his CSAIL colleagues solved a differential equation dating back to the early 1900s, enabling researchers to create an AI algorithm that can learn on the spot and adapt to evolving patterns. The new algorithm “will enable larger-scale brain simulations,” Hasani explains.
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.”
Writing for NBC Boston 10, Senior Lecturer Tara Swart highlights three exercises that can help reduce stress and anxiety. “While anxiety can be scary, understanding how our bodies and brains react during those moments can remove some of the pressure and help us take control of our nervous system," writes Swart,
Researchers at MIT have found “the brain is not wired to transmit a sharp ‘stop’ command in the most direct or intuitive way,” reports Kevin Hartnett for Quanta Magazine. The brain “employs a more complicated signaling system based on principles of calculus,” writes Hartnett.
Nature reporter Elie Dolgin writes that a new study by MIT researchers explores the role of the gene variant APOE4 in Alzheimer’s, and finds that the gene is linked with faulty cholesterol processing in the brain, impacting the insulation around nerve cells and potentially causing memory and learning deficits. “The work suggests that drugs that restore the brain’s cholesterol processing could treat the disease,” writes Dolgin.
A study by Prof. Emery Brown suggests that the combination of Covid-19 and anesthesia could prompt the human brain into a state of quiet that can last weeks or months, similar to how turtles quiet their neurons to survive winter, reports Carl Zimmer for The New York Times. The findings “might point to new ways to save people from brain damage: by intentionally putting people into this state, rather than doing so by accident.”
Prof. Matthew Wilson speaks with National Geographic reporter Brian Handwerk about his research exploring the science behind whether animals have dreams. “We have this idea of dreams being a confabulatory narrative with kind of crazy, vivid elements to it,” says Wilson. “But when we look into animal models, we’re simply trying to understand what goes on during sleep that might influence learning, memory, and behavior.”
Scientists at MIT have found that specific neurons in the human brain light up whenever we see images of food, reports Dr. Mallika Marshall for CBS Boston. “The researchers now want to explore how people’s responses to certain foods might differ depending on their personal preferences, likes and dislikes and past experiences,” Marshall.
MIT researchers have developed a new magnet-based system to monitor muscle movements that could help make prosthetic limbs easier to control, reports Brianna Silva for WHDH.
