Nano-style sheets may aid health, shield ecosystem

Microscopically, "nanomembrane" sheets made from nylon resemble a tangled web. The tiny iron oxide particles on the fiber surfaces can help clean toxic chemicals from water, but if the particles get separated from the web, ...

Deep-sea rocks point to early oxygen on Earth

Red jasper cored from layers 3.46 billion years old suggests that not only did the oceans contain abundant oxygen then, but that the atmosphere was as oxygen rich as it is today, according to geologists.

Biological wires carry electricity thanks to special amino acids

Slender bacterial nanowires require certain key amino acids in order to conduct electricity, according to a study to be published in mBio, the online open-access journal of the American Society for Microbiology, on Tuesday, ...

A role for meteoritic iron in the emergence of life on Earth

Researchers from the Max Planck Institute for Astronomy and Ludwig Maximilians University Munich have proposed a new scenario for the emergence of the first building blocks for life on Earth, roughly 4 billion years ago.

Hydrogen from water in iron nanotruss structures

Swedish researchers have discovered a new and efficient way to use electrocatalysis to produce hydrogen gas from water. Instead of using expensive and difficult-to-obtain platinum electrodes, the new method uses electrodes ...

Light amplification accelerates chemical reactions in aerosols

Aerosols in the atmosphere react to incident sunlight. This light is amplified in the interior of the aerosol droplets and particles, accelerating reactions. ETH researchers have now been able to demonstrate and quantify ...
