When roots crack and worms crunch

Roots can be "listened to" while growing – and worms when burrowing. Researchers from ETH Zurich and the French National Institute for Agricultural Research present a new method for soil analysis.

Integrated sensor could monitor brain aneurysm treatment

Implantation of a stent-like flow diverter can offer one option for less invasive treatment of brain aneurysms—bulges in blood vessels—but the procedure requires frequent monitoring while the vessels heal. Now, a multi-university ...

A hydrogen sensor that works at room temperature

Researchers at TU Delft have developed a highly sensitive and versatile hydrogen sensor that works at room temperature. The sensor is made of a thin layer of a material called tungsten trioxide.

New nerve gas detector built with legos and a smartphone

Researchers at The University of Texas at Austin have designed a way to sense dangerous chemicals using, in part, a simple rig consisting of a smartphone and a box made from Lego bricks, which could help first responders ...

Biological light sensor filmed in action

Using X-ray laser technology, a team led by researchers of the Paul Scherrer Institute PSI has recorded one of the fastest processes in biology. In doing so, they produced a molecular movie that reveals how the light sensor ...

A new way to measure energy in microscopic machines

What drives cells to live and engines to move? It all comes down to a quantity that scientists call "free energy," essentially the energy that can be extracted from any system to perform useful work. Without this available ...
