Johns Hopkins scientists uncovered microscopic “nanotube” channels that neurons use to transfer toxic molecules. While this process clears waste, it can also spread harmful proteins like amyloid-beta. Alzheimer’s-model mice showed more nanotubes early on, hinting at a link to disease development. Researchers hope to one day control nanotube formation as a potential therapy.

CO₂ ice blocks on Mars may dig gullies as they slide and sublimate in the thin atmosphere. In lab experiments, scientists recreated these eerie, worm-like movements under Martian conditions. The findings help explain unusual dune formations and deepen our understanding of how alien landscapes evolve.
