Tiny 'bridges' help particles stick together

It happens outside your window every time it rains: The soil gets wet and may form sticky mud. Then it dries. Later it might rain again. Each wetting and rewetting affects the structure and stability of the soil. These changes ...

Experts explain the effect of climate change on infrastructure

From fires in the Amazon and in Australia, to flash flooding in Europe, right across the globe we are witnessing the impact of climate change on the environment. But how does a changing climate affect key infrastructure? ...

Subtle changes, big effects

"Does the flap of a butterfly's wings in Brazil set off a tornado in Texas?," Edward Lorenz, once famously wondered at the 139th meeting of the American Association for the Advancement of Science. Scientists have recently ...

A more sustainable material to reinforce concrete structures

The next generation of ultra high-performance fiber-reinforced concrete (UHPFRC) has just been created at EPFL. The new material will be used to strengthen and to extend the life span of bridges and other structures—both ...

Ancient rhinos roamed the Yukon

In 1973, a teacher named Joan Hodgins took her students on a hike near Whitehorse in Canada's Yukon Territory. In the process, she made history for this chilly region.

Bridging the nanoscale gap: A deep look inside atomic switches

A team of researchers from Tokyo Institute of Technology has gained unprecedented insight into the inner workings of an atomic switch. By investigating the composition of the tiny metal 'bridge' that forms inside the switch, ...
