Brain and cognitive sciences

For Scientific American’s special section “The Young American Scientists,” Prof. Feng Zhang speaks with Tara Haelle about the importance of investing in science and education, noting that “American science has long been the strongest engine of discovery and innovation in the world.” Zhang shares: “I’m fortunate to work with extraordinary students and postdocs, but the infrastructure that lets them do their best work is under real stress: funding instability..., immigration uncertainty for international scientists and an erosion of public trust in expertise. We can lose the lead rapidly if we do not protect our innovation ecosystem.” 

Prof. Emery Brown speaks with Scientific American reporter Tara Haelle for Scientific American’s special “Young American Scientists” section, discussing the evolution of the field of neuroscience and why he is optimistic about the future of scientific research in the U.S. “I am optimistic because I see new and exciting findings being discovered every day,” says Brown. “With [MIT] President [Sally] Kornbluth’s support, [the university] has developed its Health and Life Sciences (HEALS) program to encourage MIT faculty to look more deeply into solving health care problems. The enthusiasm for HEALS has been contagious across the campus.” 

Visiting Scientist Alice Stanton speaks with Scientific American reporter Tanya Lewis about her work developing miBrain, a 3D model of the human aimed at helping scientists “better understand neurological diseases such as Alzheimer’s and Parkinson’s so researchers can develop personalized treatments for them.” Says Stanton of the need for stable support for scientific research: “When we have a loved one who gets sick, we want a treatment—we want something to cure them. It doesn’t come out of thin air.”

Forbes contributor Michael T. Nietzel spotlights the 120 new members and 25 international members elected by the National Academy of Sciences for 2026. Several MIT faculty members – including Professors Michale Fee, Gareth McKinley, Keith Nelson, Bengt Holmstrom and Catherine Wolfram – were selected. 

Researchers from MIT, Harvard and Yale have found “that people who meditate regularly show measurable increases in brain thickness in areas responsible for attention and sensory processing,” reports Luis Prada for Vice. “The research team plans larger studies to track changes over time and explore how meditation might influence neural connections and cognitive aging,” writes Prada. 

Chronicle reporter Jon Rineman spotlights Prof. Li-Huei Tsai’s work researching how stimulation via light and sound could one day potentially be used to help fight Alzheimer’s disease. “People who continued with this treatment, their memory capacity really has been maintained at a steady state level,” explains Tsai. “And in a couple of patients, their Alzheimer’s biomarkers actually significantly reduced.” 

A new study by researchers at MIT and elsewhere has found a correlation between addiction and eye care, reports Hadley Barndollar for MassLive. “The study found nearly half of the patients with opioid use disorder being treated for the eye infection were eligible to initiate medication-assisted treatment,” explains Barndollar. “But medications were only initiated when an addiction consult occurred, highlighting how much more eye doctors responding to emergency rooms can offer patients beyond vision care.” 

Prof. Rebecca Saxe speaks with GBH’s Morning Edition host Mark Herz about the importance of maintaining social commitments. “People who have community and social relationships have better physical and mental health,” explains Saxe. “It actually helps with mortality. You live longer if you have strong social relationships.” 

MIT researchers have developed “GelSight,” a system that provides robots with a sense of touch, reports Ben Guarino for Scientific American. “GelSight can identify by touch the tiny letters spelling out LEGO on the stud of a toy brick,” explains Guarino. 

Researchers at MIT studying amblyopia – commonly known as lazy eye – have found that anesthetizing the retina could restore visual responses, reports Emma Frederickson for Popular Mechanics. “Their recent findings could reshape the way we think about vision loss,” writes Frederickson. 

Two new research papers by scientists from MIT and other institutions find that AI chatbots are successful at shifting the political beliefs of voters, and that the “most persuasive chatbots are those that share lots of facts, although the most information-dense bots also dole out the most inaccurate claims,” reports Sarah Kuta for Smithsonian Magazine. “If you need a million facts, you eventually are going to run out of good ones and so, to fill your fact quota, you’re going to have to put in some not-so-good ones,” says Visiting Prof. David Rand. 

A new study by MIT researchers has found that “AI chatbots were surprisingly effective at convincing people to vote for a particular candidate or change their support for a particular issue,” reports Alex Wilkins for New Scientist. “Even for attitudes about presidential candidates, which are thought to be these very hard-to-move and solidified attitudes, the conversations with these models can have much bigger effects than you would expect based on previous work,” says Visiting Prof. David Rand. 

Prof. Earl Miller speaks with National Geographic reporter Dana Binfet about the impact of increased social media and digital platform use on the brain. “Brain rot is not really rotting our brains,” explains Miller. “It’s constantly creating an environment that our brains are not equipped to deal with—that's the real problem. We’re single-minded creatures and when all this information is coming at us, we want to consume everything and it’s hard to turn off that desire.”

Wired reporter Steven Levy spotlights Research Scientist Sarah Schwettmann PhD '21 and her work investigating the unknown behaviors of AI agents. Schwettmann has co-founded Transluce, a nonprofit interpretability startup “to further study such phenomena,” writes Levy.

In an effort to develop non-invasive ways to treat depression, PTSD, brain tumors and other conditions, researchers from MIT Lincoln Lab are looking to better understand human consciousness, reports Steph Solis for Axios. “There's the goal to analyze how it could help understand or treat PTSD and mood disorders in veterans,” says Solis of the inspiration for this research, “and then there's the existential question that stumps neuroscientists — how does our human experience arise from brain activity?”
