Planning greener, healthier cities from the data up

A new study by the University of South Australia indicates important gaps in urban planning data need to be addressed to ensure key development decisions are evidence-based.

Ancient enzymes can contribute to greener chemistry

A research team at Uppsala University has resurrected several-billion-year-old enzymes and reprogrammed them to catalyze completely different chemical reactions than their modern versions can manage. The method can be used ...

Balancing the economy while saving the planet

If you make your bio-product 100% sustainable it may be way too expensive to produce. If you make it less environmentally friendly, you may, at some point, end up having a feasible product that can compete on market terms. ...
