How long can a Bull shark survive without any blood in the brain aka hypoxia?
The remarkable resilience of bull sharks has sparked considerable debate, particularly concerning their capacity to maintain neurological function—and jaw movement—following significant blood loss. Observations of post-mortem jaw snapping, as reported by /u/Anxious-Ad7993, have prompted questions regarding survival time under hypoxic conditions. While mammalian brains typically cease function within minutes of oxygen deprivation, shark neurobiology exhibits unique adaptations. Empirical data suggests bull sharks, and similar species, may exhibit neurological activity for significantly longer—potentially exceeding 5 minutes—due to differences in metabolic rate and oxygen utilization.

A new sort of Alzheimer’s drug shows glimmers of promise
Early clinical trial data indicates a novel Alzheimer’s drug demonstrates promising, albeit complex, therapeutic potential. The experimental treatment demonstrably lowered tau protein levels—a key pathological indicator—within the brains of participants, correlated with a measurable slowing of memory decline. Notably, the study revealed an unexpected, and as yet unexplained, association between drug response and a specific genetic biomarker. Further longitudinal research is critical to validate these findings and fully characterize the drug’s efficacy and safety profile.
