Using 60% less water in paper production

An EPFL researcher has developed a mathematical model for optimizing heat transfer in factories and dramatically reducing water and energy consumption. The model could, in theory, cut water use by 60 percent at a Canadian ...

Comparing the world's mega-canals

There are more and more big canals and pipelines transporting fresh water from places where it is abundant to places where it is needed for drinking—or for industry and agriculture. Thirty-four such mega-systems are already ...

New science helps put spotlight on unseen global impacts

As the world grows more connected, "out of sight, out of mind" looms as a perilous consequence of globalization. A sustainability scholar presents an integrated way to track the many footprints that are made in global transactions ...

Novel algorithm simulates water evaporation at the nanoscale

We are all familiar with boiling a pot of water—flame from a stove heats the base of a metal pot, the metal transfers the heat to the water, and the temperature goes up and up until the water boils. Professor Shalabh Maroo ...

Measuring the pulse of trees

I read many years ago that if you wanted a tree to recognise you, you would need to sit quietly at its base for a week. Very Zen!

Efficient thermal cooling and heating

Thermal systems use heat to produce cold, and vice versa. To do so, a material is needed that can dissipate water vapor particularly well and quickly. A new method simply applies this property as a layer onto the components.

Study explores atmospheric impact of declining Arctic sea ice

There is growing recognition that reductions in Arctic sea ice levels will influence patterns of atmospheric circulation both within and beyond the Arctic. New research in the International Journal of Climatology explores ...
