Cerebral small vessel disease Alzheimer's link revealed in new early-stage study
Researchers discovered that blood vessel damage in genetic Alzheimer's occurs well before traditional amyloid plaques form. Mouse models with a specific PSEN1 mutation showed leaky blood-brain barriers and twisted microvessels early on, pointing to vessel health as a primary target.

Did Ancient Farmers Accidentally Hack Maize Crop Yield?
Modern corn allocates significantly more energy directly to its grain than its wild ancestors thanks to a specific DNA modification. Scientists have mapped a genetic loop that directs nutrients straight into the kernels, sustaining grain output even in poor soil.
Did Chemists Just Capture Elusive Gold Nitrenes?
Chemists have successfully isolated gold nitrenes, highly reactive gold-nitrogen species previously thought impossible to catch. By using light to trigger a reaction, the team trapped the molecule in crystalline form to analyse its structure. The findings establish a brand-new framework for gold-mediated nitrogen-atom transfer chemistry.
How Restoring Cerebrospinal Fluid Clearance Could Transform Brain Health
Researchers mapped a vital drainage pathway for brain waste in mice and monkeys. Delivering targeted proteins via the nose restored impaired cerebrospinal fluid clearance in aged mice, offering new targets for neurodegenerative research.
