Stanford Medicine is reported to have revealed that the human brain functions as two distinct organs rather than a single one. The claim was picked up by broadcaster KRON 4 and has drawn large public attention. Details of the research, its methods and peer review status have not been provided in the coverage seen so far, so the scientific basis of the claim remains to be confirmed.

Researchers report observing a deadly brain cancer physically remodel brain tissue as the tumor grows. The findings offer a rare real-time view of how glioblastoma-type cancers distort and reorganize the brain, potentially improving understanding of disease progression and treatment approaches.

New research reported by ScienceDaily suggests glucosamine, a widely used joint supplement taken by millions for arthritis and cartilage health, may be associated with faster progression of Alzheimer's disease. The finding is drawing attention because the supplement has long been viewed as safe and is commonly self-prescribed, raising questions about its effects on the ageing brain.

A news segment examines the state of scientific knowledge on chronic traumatic encephalopathy, the brain condition linked to repeated head impacts in contact sports. The report outlines what researchers have established so far and highlights the significant gaps that remain, including how to diagnose CTE in living patients and who is most at risk. The topic continues to draw attention amid ongoing concern over head injuries in football and other sports.

Researchers report identifying a molecular switch triggered by stress that appears to drive depression, according to a report by Bioengineer.org. The finding could shed light on how chronic stress produces changes in the brain that lead to depressive symptoms, potentially opening new avenues for treatment. Details of the underlying study, including the research team, publication venue and evidence, were not provided in available coverage.

New research suggests radiation exposure may trigger a key feature of Alzheimer's disease in the brain. According to ScienceAlert, the findings point to radiation potentially initiating one of the hallmark brain changes associated with the disease, adding to growing scientific interest in environmental factors that may contribute to Alzheimer's risk.

Scientists report identifying a previously unknown brain circuit that could explain why heart attacks often worsen after the initial event. The finding suggests the brain may trigger processes that compound damage to the heart in the hours and days following an attack. If confirmed, the discovery could open new avenues for treating patients after a heart attack and reducing long-term harm.

A new study reports that adults with higher levels of a particular vitamin showed healthier results on brain scans. The finding, highlighted by health news outlets, adds to ongoing research into how nutrition may influence brain health and could affect public guidance on diet and supplements as people age.

Scientists have produced a map of gene activity in the brain's prefrontal cortex, the region involved in decision-making, memory and personality. The work offers a detailed picture of which genes are switched on across cell types in this area, potentially aiding research into mental illness and neurological disease. Beyond the headline, no further details about the study, the research team or its publication are available.

A new study reports that autism is linked to two opposing molecular patterns in the brain, suggesting the condition may involve distinct biological profiles rather than a single underlying signature. Researchers say the findings could help explain why autism presents so differently across individuals and may guide more targeted approaches to studying and eventually treating the condition.

Radio-Canada reports on new research suggesting the brain may have evolved from the fusion of two ancestral organs. The idea, tied to studies of embryonic cells, challenges the classic view of how the brain developed over evolutionary time and is drawing attention among French-speaking science and neuroscience audiences discussing its implications for biology and evolution.

Researchers report a surprising connection between bone density and brain aging, according to a new study covered by SciTechDaily. The finding suggests skeletal health may be tied to how the brain ages, a link that could shape future research into dementia and osteoporosis. Science commentators are sharing the study, with many noting it challenges the usual separation between bone and brain research.

New research highlights a paradox in REM sleep: the brain's fuel supply appears to rise during dreaming, yet energy is still being drained. Scientists suggest that the intense neural activity behind vivid dreams may consume more energy than the increased supply can offset. The findings could reshape understanding of why sleep is restorative and how dreaming supports brain function.

Slime molds — single-celled organisms with no brain — can solve mazes, optimize networks and make decisions, reigniting scientific debate over whether 'intelligence' applies without neurons. The discussion touches on how biology should define cognition, with critics arguing the term is being stretched too far and others seeing slime molds as evidence that problem-solving exists well beyond animals.

Single-celled slime molds, which lack brains yet can solve mazes, optimize networks, and learn simple patterns, are at the center of a growing scientific dispute over how intelligence should be defined. Researchers disagree on whether such abilities reflect genuine cognition or simpler biological processes, a question with implications for neuroscience, philosophy, and artificial intelligence.
