In an Alzheimer’s care unit, a striking scene unfolds time and again. A person who no longer recognizes their loved ones, who struggles to find words or remains silent, suddenly begins to sing. The singing is not always accurate or entirely faithful, but the melody, the rhythm, and sometimes even the lyrics emerge with unsettling…
We spend a large part of our days not entirely where we are. While our eyes are fixed on a screen, a book, or a conversation partner, the mind often drifts toward thoughts that have no immediate connection with the situation at hand. This discreet but pervasive phenomenon is so common that researchers estimate it…
Each new year acts as a signal. It invites reflection, projection, and a reconsideration of what once seemed firmly established. Biologically, however, nothing distinguishes the brain from one day to the next. The same neural circuits remain active, the same habits continue to shape behavior, and the same constraints weigh on decision making. Despite this…
For a long time, schooling was conceived within four walls. Protective, structured, reassuring walls. Over the past decade, however, a quiet shift has been taking place in schoolyards, public parks, and sometimes at the edge of forests. What if learning outdoors were not a pedagogical whim, but a science based response to some of the…
Remembering a place, a route, or a familiar event feels effortless. However, beneath this apparent simplicity lies a highly complex orchestration of electrical signals. A study published in Nature Communications in 2025 by a research team from the University of Freiburg reveals that human memory partly relies on a rhythmic coordination mechanism between neurons, comparable…
It often begins harmlessly. A few videos to soothe a child after a difficult day, a cartoon to prepare dinner in peace, an app said to boost language development. Gradually, and almost without noticing, the screen slips into every moment of daily life. The evening routine turns into a struggle. Sleep becomes possible only after…
For decades, brain aging has been investigated mainly through hormonal, metabolic and inflammatory lenses. A recent discovery suggests that part of the answer may lie deeper, within the genome’s structural organisation itself. Researchers at the University of California San Francisco have shown that in females, the inactive X chromosome, normally silenced to prevent double gene…
Fear is a vital instinct. It alerts, protects, and ensures survival. When this mechanism becomes dysregulated, fear can persist long after the threat has disappeared. The memory of danger remains active even in safety. This pattern is seen in certain phobias and in post-traumatic stress disorder (PTSD), where the brain continues to react to cues…
Forgetting a painful memory on purpose has been a dream as old as memory itself. Since antiquity, humanity has sought in forgetfulness a way to ease its inner wounds. In Greek mythology, the souls descending into the Underworld would drink the waters of the river Lethe to erase their memories before being reborn into a…
Long regarded as mere support cells, astrocytes are now emerging as key players in the orchestration of sleep. Recent studies reveal that these glial cells do far more than accompany neurons they actively regulate sleep cycles, especially slow-wave sleep, which is vital for recovery and memory consolidation. From the ventrolateral preoptic nucleus (VLPO) a crucial…
