Deep insights. Simply put

Carefully curated. Deeply researched. Free of ads and shackles.

There are brilliant content producers with the finger on the pulse. So we won’t regurgitate the news just to keep up with the crowd, except if the news needs an urgent second opinion. And this is not a rarity. We take our time to see through commercial biases, and noodle on the nuances behind the headlines. Always in an easily digestible form. An individual human may be pear-shaped but is never bell-shaped - meaning, statistical evidence for whole populations may not fit well with you if you’re an edge case or working in extremes. Like many of our patients. While on the programme or alumni membership we’ll take the topics you ask us about and tailor what it means to those like you. And while we use AI tools to help us search and type faster, rest assured, we don’t rely on anyone except the experts.

Rapid amyloid clearance in hours: what this 2025 mouse study shows us

Could the fastest way to treat Alzheimer’s disease be not to attack plaques in the brain, but to restore the brain’s clearance plumbing?

Alzheimer’s disease has long been one of medicine’s most stubborn challenges. For decades, scientists have approached this battle on two fronts: stopping the buildup of amyloid plaques in the brain, and getting drugs past the brain’s ultra-strict protective barrier, the Blood-Brain Barrier (BBB).

A recent 2025 paper in Signal Transduction and Targeted Therapy reported a striking finding in an Alzheimer’s mouse model: using nanotechnology, they were able to half brain amyloid within 2 hours, and importantly, restored spatial learning and memory in the mice, comparable to their normal peers.
