Computer simulation discloses new effect of cavitation: Steam bubbles in fast flowing fluids obviously also result from chemical surface properties; use for reducing wear in pumps and plain bearings
A cavitation bubble is formed in the lubricant between the oil-attracting (yellow) and the oil-repellent surface (black). When used as a buffer, it might reduce wear.

Scientists Part the Clouds on How Droplets Form
Cloud droplets form when the amount of water vapor reaches a threshold value. Larger cloud droplets form when organic molecules (in red) are present on the surface instead of dissolving in the interior, or bulk, of the droplet.

Newly discovered organic nanowires leave manmade technologies in their dust
The discovery, featured in the current issue of Scientific Reports, describes the high-speed protein fiber produced by uranium-reducing Geobacter bacteria. The fibers are hair-like protein filaments called "pili" that have the unique property of transporting charges at speeds of 1 billion electrons per second.

Entanglement becomes easier to measure: New protocol to detect entanglement of many-particle quantum states
Quantum systems consisting of many particles can enter highly intricate states with strong so-called multiparticle entanglement. A new-found theoretical relation now allows extracting it with standard tools available in scattering experiments.
