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 ...

Digital penicillin production

TU Wien and Sandoz GmbH have successfully implemented a real-time computer simulation of the complex growth behaviour of penicillin producing organisms. This simulation now helps to keep the production process under control.

Shaken, and stirred: Scaling up bioreactors' fluid dynamics

Bioreactors are widely used to produce different therapeutics in the biopharmaceutical and regenerative medicine industries. Drug development relies on small multi-well plates shaken around an orbital diameter, while production-scale ...

Upstream trenches, downstream nitrogen

Water quality scientist Laura Christianson is working on a solution to the "dead zone"—an area with dangerously low levels of oxygen— in the Gulf of Mexico. Christianson lives over a thousand miles north of the Gulf in ...
