A new ‘molecular lantern’ detects brain metastasis in mice by inserting a probe thinner than a hair into the brain

A new technique detects brain metastasis in mice by inserting a thin probe into the brain, providing information on chemical composition. The technique uses vibrational spectroscopy and has the potential to analyze molecular changes caused by tumors or injuries without altering the brain beforehand.

Sleep apnea linked to changes in the brain

A recent study published in Neurology has found that people with sleep apnea tend to have a larger hippocampus, a region crucial for memory and thinking. The study, which included mostly Latino participants, also discovered that lower oxygen levels during sleep were associated with increased brain volume and white matter hyperintensities.
