Glymphatic system research highlights sleep and interventions
The glymphatic system clears brain waste via channels around blood vessels. Sleep boosts its flow, and researchers are testing drugs, red‑light therapy, carbon‑dioxide inhalation, exercise, breathing changes, and sleep position to enhance clearance.
Key points
Sleep reduces glymphatic flow by about 95 % when mice are awakened, compared to sleeping state.
Beta‑amyloid clearance is roughly twice as fast in sleeping mice versus awake mice.

Artificial upwelling, marine cloud brightening, and Terranova flood‑mitigation robot
Researchers propose large‑scale artificial upwelling and marine cloud brightening to cool Pacific sea‑surface temperatures and dampen El Niño. A California start‑up, Terranova, unveiled a robot that injects wood‑slurry to raise land elevation for flood protection. Both concepts remain experimental and lack deployed technology.
Key points
Artificial upwelling would need ~5.8 million km of pipe to cool the tropical Pacific, about twice all existing pipelines.
Terranova’s robot can lift a 4,000 m² area by ~30 cm per day using a 12–18 m deep well and wood‑slurry injection.
