Widening metal tolerance for hydrogels

Researchers seeking to develop self-healing hydrogels have long sought to mimic the natural ability of mussels to generate strong, flexible threads underwater that allow the mussels to stick to rocks.

Structures in seaweed shed light on sustainability

Brown algae are not just seaweed that float in the ocean and tangle swimmers' feet—they also contains a secret. In its cell wall, brown algae hold the polysaccharide alginate, one of the most abundant carbohydrates in the ...

Stabilizing a cliff using biomineral binders

EPFL spin-off Medusoil has successfully tested its ground-stabilization process on cliffs subject to surface erosion. The company's biomineral-based solution can be used to stabilize sandy and gravelly subsoils to safeguard ...

An ultrafast glimpse of the photochemistry of the atmosphere

Our lives are governed by submicroscopic processes in the nanocosmos. Indeed many natural phenomena begin with a minuscule shift in the states of atoms or molecules, triggered by radiation. One such process has now been elucidated ...

How changes in land use could reduce the browning of lakes

Over the past 50 years, the water in lakes and watercourses has turned increasingly brown. The so-called browning has a negative impact on both drinking water production and ecosystems. If nothing is done, the water is likely ...
