A study published in the Journal of Gerontology examines the relationship between napping characteristics and the onset of dementia, finding that how long and how often people nap may be associated with their risk of developing the condition. The findings are drawing attention as readers discuss what the results suggest about sleep and brain health in older adults.

Tennessee is drawing attention on two fronts. In the Chattanooga area, local media are publishing voter guides ahead of Tuesday's polls, telling residents what to know before casting ballots. Separately, national coverage is following the case of Christa Pike, whose attorneys said she was believed to be brain-dead before she woke up unexpectedly, a development described as a shock to everyone involved.

X Square co-founder and COO Yang Qian said the company wants robots to shift from being driven by code to being driven by common sense. The comments come amid a wider push in China's robotics industry, where manufacturers have demonstrated impressive physical capabilities and are now competing to develop smarter, more autonomous robot brains.

New research reported by Science Daily finds that children who consume more ultra-processed foods show a troubling brain response. The findings add to growing concern about how heavily processed diets may affect children's neurological development, though details of the study, including its size and methods, are not yet clear from the available report.

A peer-reviewed Nature study analysed 2,357 human neurons and found that widespread genomic copy-number changes are common before birth but become far rarer afterward. Researchers interpret this as evidence of a perinatal quality-control process in which the developing brain removes neurons carrying heavily altered genomes, offering new insight into how genomic integrity is maintained during human brain development.

New reporting highlights growing research suggesting frequent or extended daytime napping may be tied to a higher risk of developing dementia, or could serve as an early warning sign of cognitive decline. Researchers are still weighing whether long naps cause harm, reflect underlying brain changes, or both, and experts caution more study is needed before drawing firm conclusions.

A new report suggests the brain contains a previously little-understood fear mechanism that could help explain how anxiety disorders and PTSD develop. The finding, covered by Science Daily, points to new research into how fear responses are generated and stored in the brain. Researchers hope a clearer picture of this mechanism could eventually guide better treatments for people living with trauma-related conditions.

Researchers at the Max Planck Florida Institute for Neuroscience have published findings on how neural circuits reorganise after the onset of visual experience. The work, announced via EurekAlert, offers new insight into how the developing brain adapts its wiring in response to sensory input, a process relevant to understanding developmental neuroscience and plasticity.

The Fisher Center for Alzheimer's Research Foundation reports that more years spent in education are linked to a lower risk of developing Alzheimer's disease. The finding adds to evidence that education builds cognitive reserve, which may help the brain compensate for damage associated with dementia. Researchers and health commentators have long debated how schooling, lifestyle and genetics interact to shape dementia risk.

A new study published in Developmental Cell reports that ASPM mutations known to cause microcephaly disrupt mitotic spindle orientation and delay the specification of human outer radial glia cells. The finding offers mechanistic insight into how these genetic defects impair expansion of the neural progenitor population during cortical development, a key step in normal brain growth.

Researchers have published a comparative study of brain development in humans and great apes, aiming to identify what biologically distinguishes the human brain from that of our closest relatives. The findings are being shared via EurekAlert! as part of ongoing scientific coverage of human evolution and neuroscience.

A new study of 113 Japanese preschoolers suggests that children who blink more often may be better at switching between mental rules, a sign of cognitive flexibility. Researchers link blink rate to brain systems involved in shifting attention. The findings could help identify how young children develop executive function and problem-solving skills.
