Scientists enrich nitric oxide-reducing microbes in bioreactor

Nitric oxide (NO) is a fascinating and versatile molecule, important for all living things as well as the environment. It is highly reactive and toxic, organisms use it as a signaling molecule, it depletes the ozone layer ...

Bioreactors chip away at nitrogen pollution

Bioreactors are underground trenches filled with woodchips. They have been gaining traction as a tool to remove nitrogen from the water in agricultural settings.

How the humble woodchip is cleaning up water worldwide

Australian pineapple, Danish trout, and Midwestern U.S. corn farmers are not often lumped together under the same agricultural umbrella. But they and many others who raise crops and animals face a common problem: excess nitrogen ...

A decade-long quest to build an ecosystem in a room

Yesterday the MELiSSA pilot plant at the University of Barcelona celebrated 10 years spent demonstrating the ideal technologies to recycle waste from space missions into air, water and food.

Bioreactor device helps frogs regenerate their legs

A team of scientists designed a device that can induce partial hindlimb regeneration in adult aquatic African clawed frogs (Xenopus laevis) by "kick-starting" tissue repair at the amputation site. Their findings, appearing ...
