Eliminating cracks in 3D-printed metal components
Eliminating cracks in 3D-printed metal components
Researchers at EPFL have developed a new laser 3D-printing technique to manufacture metal components with unprecedented resistance to high temperature, damage and corrosion. The method has applications in fields ranging from aerospace to power-generating turbines. 3D printing, also known as additive manufacturing, has revolutionized the way components are made, setting new standards in terms of production speed when geometric complexity is high.

Gummy-like robots could help prevent disease
Gummy-like robots could help prevent disease
EPFL scientists have developed microscopic, hydrogel-based muscles that can manipulate and mechanically stimulate biological tissue. These soft, biocompatible robots could be used for targeted therapy and to help diagnose and prevent disease. Human tissues experience a variety of mechanical stimuli that can affect their ability to carry out their physiological functions, such as protecting organs from injury.

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.

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.

A nano car with molecular 4-wheel drive
A nano car with molecular 4-wheel drive
Reduced to the max: the emission-free, noiseless 4-wheel drive ca represents lightweight construction at its most extreme. The nano car consists of just a single molecule and travels on four electrically-driven wheels in an almost straight line over a copper surface. A number of chemists aim to use similar principles and concepts to design molecular transport machines, which could then carry out specific tasks on the nano scale.

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.
