How exercise keeps our brains healthy as we age
There's growing evidence linking brain health with exercise. A new study from Victoria University (VU) strengthens the case for exercise as a critical part of protecting the brain from age-related decline like dementia and Alzheimer's disease.
Our brains predict the world—but learn most when they get it wrong
Few moments in a soccer game are more electrifying than the penalty kick. The goalkeeper stands, waiting for the kick—and even before the ball is struck, they must predict where it is going and spring into action.

Geometric neural 'map' may help bilingual brains navigate between languages
Anyone who speaks more than one language knows the feeling of expressing the same thought through entirely different linguistic lenses. A new study by researchers at Rice University and Baylor College of Medicine reveals that the key to this translation ability is a shared geomet
New mechanism found for neuronal death in Alzheimer's and frontotemporal dementia
New mechanism found for neuronal death in Alzheimer's and frontotemporal dementia
Markers of a new mechanism for cell death, called karyoptosis, have been found in the brains of patients with Alzheimer's disease and frontotemporal dementia (FTD).
How the brain's physical shape guides its internal wiring
A new study led by Monash University researchers has shed light on the factors shaping the intricate wiring of our brains. The research, published in the journal Cell, reveals that the brain's complex wiring diagram, known as the cortical connectome, does not form at random. Inst
Dementia-causing substance turns into a therapeutic 'switch' with new Alzheimer's drug str
A substance that worsens dementia has become a "switch" that initiates treatment. KAIST researchers have developed a new therapeutic approach that uses hydrogen peroxide (H₂O₂), a reactive oxygen species that damages cells and increases in the brains of patients with Alzheimer's
Zebrafish brains reveal alternate route for senses to the forebrain shared with mammals
Line up the brains of a fish, bird and a mammal, and something unexpected comes up. You do not see three different answers to the problem of making sense of the world. You see one answer, tilted three different ways. "You can really see it's almost like a continuum," says Emre Ya
Speaking another language could slow aging in the brain
Speaking another language could slow aging in the brain
People who speak more than one language seem to have younger brains, according to research presented at the Federation of European Neuroscience Societies (FENS) Forum 2026. Our brains are made up of billions of nerve cells that need to communicate with one another. As we age, con
PET scans reveal stage-linked tau signal in Huntington's disease brains
A study conducted by the Sant Pau Research Institute (IR Sant Pau) and Hospital de Sant Pau has identified for the first time in living individuals a brain pattern related to the tau protein that changes according to the stage of Huntington's disease. This discovery opens the doo
Babies' brains respond to music by three months of age—while moving to it begins by their
A study suggests babies' brains recognize music from as young as 3 months of age, while spontaneous movements to music emerge by their first birthday and their ability to match movements to it develops later.
Brainstem neurons map whisker touch into object distance, reveals mouse study
If you are crossing an unfamiliar room in the dark, you may grope around a bit to get a sense of your space. But for many animals, feeling out a space comes more naturally. A mouse, for instance, can efficiently navigate in the dark just by grazing its whiskers against walls and
Brains of teens with autism 'tune in' less to unfamiliar voices, study finds
Like other teenagers, teens on the autism spectrum are itching to exercise their social muscles. They hope for new friends, fun with people who share their interests, maybe even a romantic relationship.
