Scientists have uncovered an early brain mechanism that may help explain why people carrying the APOE4 gene face a higher risk of Alzheimer’s disease. For millions of people who carry the APOE4 gene, the strongest known genetic risk factor for Alzheimer’s disease, changes in brain activity may start years before memory problems become noticeable. Researchers [...]A new study challenges the long-held idea that habits form only through slow, gradual repetition. What if your habits don’t form through countless repetitions over months or years? What if the brain can decide, almost instantly, that a behavior is no longer worth thinking about? That possibility is at the center of a new Johns [...]A rescued sea lion is shaking up what scientists thought they knew about rhythm and the brainBrain scans suggest long COVID’s biggest clues may lie in the brain’s emotion centers, not widespread inflammation. A new brain imaging study suggests that persistent symptoms of long COVID may not be driven by ongoing brain inflammation, as many researchers have suspected. Scientists in Finland used advanced imaging techniques to examine the brains of people [...]Researchers suggest that old psychoanalytic ideas and modern brain science may be describing the same mental processes from different angles. More than a century after Sigmund Freud developed his influential theories of the mind, some researchers believe modern neuroscience may be arriving at surprisingly similar conclusions. A new paper published in the neurocognitive journal Entropy [...]Volcano Hazards • Lahars • Rain + Ash = Mudflow • Go back to Strange Sounds Heavy rain on Mount Merapi triggered a “cold lava” flood — a lahar — surging downriver, killing people and dragging vehicles. When intense rainfall hits ash-covered slopes, loose volcanic debris turns into a fast-moving slurry that can carry boulders, […]
