Liquid shock absorbers
Liquid shock absorbers
Researchers have determined how certain liquids stiffen in response to powerful impacts. At first glance, colloids resemble homogeneous liquids such as milk or blood plasma. But in fact they consist of particles in suspension. Some colloids have remarkable properties: they may stiffen following an impact and absorb surface shocks.

Hydroelectric power plants have to be adapted for climate change
Hydroelectric power plants have to be adapted for climate change
Of all the electricity produced in Switzerland, 56% comes from hydropower. The life span of hydroelectric plants, which are massive and expensive to build and maintain, is measured in decades, yet the rivers and streams they depend on and the surrounding environment are ever-changing.

Scientists solve a long-standing mystery about wear
Scientists solve a long-standing mystery about wear
17.06.16 - It generates particulate-matter air pollution and degrades mechanical parts. Adhesive wear a major, yet poorly understood problem. Using simulations, researchers from EPFL offer new insights into what happens when seemingly smooth surfaces rub against each other. Adhesive wear can cause machine failure, particulate-matter air pollution, and many other societal woes.

The ductility of magnesium explained
The ductility of magnesium explained
22.10.15 - Zhaoxuan Wu and William Curtin of the Laboratory for Multiscale Mechanics Modeling (LAMMM) have solved the 40-year-old scientific riddle of the low ductility magnesium. Magnesium is the lightest metal found on earth; it is four times lighter than steel and a third lighter than aluminum.

A brain area responsible for grasping
A brain area responsible for grasping
A research has shown that limb motor control is regulated by a selective synaptic connectivity matrix between the brainstem and the spinal cord. In particular, the researchers have pinpointed a brainstem area responsible for the control of grasping. This is the first time it has been possible to link defined neuronal circuit elements unequivocally to a specific phase of movement.

X-rays film inside live flying insects  in 3D
X-rays film inside live flying insects in 3D
Scientists have used a particle accelerator to obtain high-speed 3D X-ray visualizations of the flight muscles of flies. The team developed a groundbreaking new CT scanning technique at the PSI's Swiss Light Source to allow them to film inside live flying insects. 3D movies of the blowfly flight motor offer a glimpse into the inner workings of one of nature's most complex mechanisms, showing that structural deformations are the key to understanding how a fly controls its wingbeat.

Turbulence ahead
Turbulence ahead
Although the wind may blow smoothly onto a wind turbine, it comes out the other end shredded into a complex collage of whorls, large and small. In a wind farm, the turbulent wake generated by the first row of turbines drives the turbines in the next rows, which produce up to 40% less power and suffer more from bumpier winds.

New-generation sensor combines lasers and mechanics
New-generation sensor combines lasers and mechanics
Scientists have developed a rapid, precise opto-mechanical measurement system that can be embedded into a silicon chip. This new technology could revolutionize the domain of sensors and atomic force microscopy. Resonators are used to detect infinitesimal quantities of matter in the atmosphere. Here's how it works: when a microscopic string comes into with a particle or a gas molecule, it vibrates.

Bridges get a quick check-up
Bridges get a quick check-up
Engineers have developed a new imaging technique that lets them see the insides of massive concrete bridges. Much like a sonogram, this technique provides quick, easy-to-interpret images, so that the health of these expensive structures can be assessed and monitored. The patient weighs several tons and is hundreds of meters long.

Testfahrten eines Marsmobils im High-Tech-Sandkasten
Oerlikon Space is currently testing an autonomous robotic vehicle for Mars; in the year 2015, as part of its ExoMars scientific mission, the European Space Agency (ESA) plans to land an autonomous robot of this type on the Red Planet to search for signs of life there.
