Washing hands despite lack of water

Even though the water we've used for washing hands is barely contaminated, it usually goes down the drain. A newly developed system allows handwashing water to be recycled, thus not only saving water, but also helping to ...

Origami inspires highly efficient solar steam generator

Water covers most of the globe, yet many regions still suffer from a lack of clean drinking water. If scientists could efficiently and sustainably turn seawater into clean water, a looming global water crisis might be averted. ...

An atom-thick graphene membrane for industrial gas separation

Chemical engineers at EPFL have demonstrated for the first time that an atom-thick graphene membrane can separate gas mixtures with a high-efficiency. The "ultimate" membrane is scalable, making it a breakthrough for industrial ...

Protecting plants intelligently

We must reduce the environmental and health risks of pesticides. However, rather than banning them completely, Robert Finger advocates an intelligent approach to crop protection.
