Stanford Medicine is being widely cited for a claim that the human brain is actually two organs rather than one. The finding, reported by KRON 4, has drawn large public attention as audiences debate what a two-organ model would mean for neuroscience and medicine. Details of the underlying research have not been made available in the coverage cited.

Chronic traumatic encephalopathy is back in the news, with coverage examining the current state of scientific knowledge about the degenerative brain disease linked to repeated head impacts. Reports emphasise that while researchers have documented CTE in athletes and others with head trauma histories, key questions remain open, including how widely it occurs, how to diagnose it in living people, and how repeated hits translate into disease.

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.

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 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.

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.

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.
