Writing for CNBC, Senior Lecturer Tara Swart explains how an unexpected financial windfall can impact the brain. Swart says there, “are three remarkable things that happen to your brain when you unexpectedly receive a large sum of money overnight,” a dopamine deluge, the five stages of grief and a shift in perspective and social dynamics.
Prof. David Rand speaks with Wall Street Journal reporter Christopher Mims about the impact of generative AI on the spread of misinformation. “When you show people deepfakes and generative AI, a lot of times they come out of the experiment saying, ‘I just don’t trust anything anymore,’” says Rand.
Cognito Therapeutics, founded by Prof. Ed Boyden and Prof. Li Huei Tsai, has developed a “specialized headset that delivers 40Hz auditory and visual stimulation” to the brain, which could potentially slow down the cognitive decline and neurodegeneration in Alzheimer’s disease, reports William A. Haseltine for Forbes. Prof. Li-Huei Tsai “and her team speculated that if gamma wave activity is reduced in Alzheimer’s disease, perhaps, artificially stimulating the brain may enhance synchronized firing and restore cognition,” writes Haseltine.
Researchers from MIT and Harvard have found that an adult’s ability to “parse the early attempts of children to talk may also help the children learn how to speak properly faster,” reports Jess Thomson for Newsweek. “These adult listening abilities might help children communicate very early and highlight that speech is a good way to share information with others," says postdoctoral associate Stephan Meylan. "That said, there is a lot of diversity in how adults and children interact across the world, both within and across different social and cultural contexts. This means that there are very likely many pathways to understanding language."
Cognito Therapeutics, founded by Prof. Ed Boyden and Prof. Li-Huei Tsai, is using a 40 Hzlight-flickering and auditory headset to help slow the progression of Alzheimer’s and restore cognition, reports William A. Haseltine for Forbes. “A recent pilot clinical trial found that this technology is not only safe and tolerable for home use, but also has a positive impact on reducing symptoms associated with age-related neurodegeneration,” writes Haseltine.
Researchers at MIT and elsewhere have identified key cell types that may protect the brain against Alzheimer’s symptoms, reports Sara Reardon for Nature. “Most Alzheimer’s research has focused on excitatory neurons, which relay electrical signals to activate other neurons,” explains Reardon. “But the authors found that the cells with reelin or somatostatin were inhibitory neurons, which halt neuronal communication. These inhibitory cells might therefore have a previously unknown role in the types of cognitive function that are lost during Alzheimer’s.”
Sloan Senior Lecturer Tara Swart Bieber speaks with Newsweek reporter Pandora Dewan about exercises that can help improve memory. "Memory is something that can be trained using neuroplasticity, which is the brain's ability to be malleable throughout life," said Bieber.
Adjunct Prof. Tali Sharot speaks with NPR Life Kit host Marielle Segarra about how lying impacts the brain. Sharot refers to an experiment she conducted that used brain imaging technology to monitor how the brain reacts to lying and found that as adults “grew more comfortable lying, the emotional response decreased – meaning that the players became more and more desensitized to their dishonesty with each subsequent lie.”
MIT scientists have developed a new brain “atlas” and computer model that sheds insight into the brain-body connections in C. elegans worms, reports Lauren Leffer for Scientific American. “Through establishing those brain-behavior links in a humble roundworm,” writes Leffer, “neuroscientists are one step closer to understanding how all sorts of animal brains, even potentially human ones, encode action.”
Researchers from MIT and Harvard have explored astrocytes, a group of brain cells, from a computational perspective and developed a mathematical model that shows how they can be used to build a biological transformer, reports Kyle Wiggers for TechCrunch. “The brain is far superior to even the best artificial neural networks that we have developed, but we don’t really know exactly how the brain works,” says research staff member Dmitry Krotov. “There is scientific value in thinking about connections between biological hardware and large-scale artificial intelligence networks. This is neuroscience for AI and AI for neuroscience.
A number of MIT alumni including Elaheh Ahmadi, Alexander Amini, and Jose Amich have been named to the Forbes 30 Under 30 Local Boston list.
Prof. Ev Fedorenko has been studying the differences in “the neural architecture of speakers who speak languages with different properties,” reports Sofia Quaglia for Wired. “Her studies suggest that the core features of language systems in the brain seem similar across the board,” explains Quaglia.
MIT researchers have found that lawyers prefer, and better understand, simplified texts, rather than legalese, reports Jesse Greenspan for Scientific American. “The researchers presented 105 U.S. attorneys with contract excerpts written in both “legalese” and plain English and tested their comprehension and recall for each,” explains Greenspan. “While the attorneys outperformed laypeople overall, they still found the legalese contracts harder to grasp than those written in plain English.”
Researchers at MIT have developed a soft robot that can be controlled by a weak magnetic field and travel through tiny spaces within the human body, reports Andrew Paul for Popular Science. “Because of their soft materials and relatively simple manipulation, researchers believe such mechanisms could be used in biomedical situations, such as inching through human blood vessels to deliver a drug at a precise location,” explains Paul.
MIT researchers have discovered an RNA-guided DNA-cutting enzyme in eukaryotes, reports Science. “The researchers speculate that eukaryotic cells may have gained the newly identified editing genes from transposable elements—so-called jumping genes—they received from bacteria,” writes Science.
