The alternative to active transport is passive transport, which uses kinetic energy only to move the molecules. Passive transport can only move molecules from a region of higher concentration to lower ...

Inspired by micro-scale motions of nature, a group of researchers has developed a new design for transporting colloidal particles, tiny cargo suspended in substances such as fluids or gels, more ...

(Nanowerk Spotlight) Nanofluidic channels feature a unique unipolar ionic transport when properly designed and constructed. Recent research in nanofluidics has adopted reconstructed layered ...

Defying one of biology’s more persistent dogmas, a potassium channel combines functions once thought to be invariably asunder. This channel, which is found in common bacteria, incorporates a subunit ...

Lin Yang, Liang Hu, J Aaron Hipp, Kellie R Imm, Rudolph Schutte, Brendon Stubbs, Graham A Colditz and Lee Smith BackgroundTo investigate associations between active transport, employment status and ...
