Biochemists found that as active transporters in cell membranes undergo conformational changes to allow their main substrates to pass through through, small molecules like water slip through as well.

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 ...

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 ...

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 ...

(Nanowerk News) Inspired by micro-scale motions of nature, a group of researchers at the Indian Institute of Technology Madras and the Institute of Mathematical Sciences, in Chennai, India, has ...
