What’s the use of flying? Recently as a model for high-performance plastics. Researchers have discovered how to make the silk protein of lacewings in a big way biotechnologically. The resulting fibers are highly rigid and are ideal for lightweight automotive, aerospace and medical applications.

A lacewing with a spider-shaped spot on its wings was designed by the University of Arizona at Tempe (USA) selected for the list of the most bizarre discoveries of 2012.

Why do Stradivarius sound so special and unique? Researchers from Taiwan have revealed another secret of the famous violin maker Antonio Stradivari: The wood of his instruments has traces of metals, suggesting a chemical pretreatment. Maybe this was just a coincidence.

Even people who are not fans of classical music, this name is a term: Antonio Stradivari. The world-famous violinmaker lived in the Italian city of Cremona at the end of the 17th and beginning (more…)

The world’s largest biotechnology plant is being built in Hungary, where it produces methane from electricity, hydrogen and carbon dioxide. The process has been developed by a company from Planegg near Munich.

Methane production by microorganisms in the laboratory: The German company Electrochaea builds in Hungary the largest power-to-gas plant in the world, built in producing natural gas from hydrogen, carbon dioxide and electricity from renewable sources.

This wooden pavilion fascinates the senses. It consists of beech elements, which are sewn with strings. It lets the sun through, offers an unusual spatial experience and shows that you can make buildings in sewing technique. The model for the unusual pavilion was the sand dollar, a sea urchin.

The new research pavilion at the University of Stuttgart sets aesthetic standards: the wooden roof construction is connected by stitched Kevlar threads. The prototype is the structure of the shell of the sand dollar, a subspecies of the sea urchin.

A filter system that transforms salty seawater into drinking water is being put through its paces as the container ship MSC Texas travels from Hamburg to India. The trick: as an energy source, the system uses the waste heat of the ship’s engines.

MSC New York in the Port of Felixstone: The sister ship, the MSC Texas, is currently on its way from Hamburg to India with a novel filter system for drinking water. The plant only needs the waste heat of the marine engines to filter drinking water from salt water. The demonstration plant of the TU Hamburg can produce 6000 liters of drinking water daily.

Warka Water is the name given to towers made of nets that harvest water from the air in three ways: collecting rainwater, catching drops of mist and harvesting condensation , The tower is named after an Ethiopian fig tree. It is intended to improve the supply of drinking water in countries such as Ethiopia. The invention has now been awarded a prize.

Warka Water: The Water Harvesting Tower has now been awarded the World Design Impact Prize. Every two years, it honors design projects that add social value.

Offshore wind turbines are exposed to enormous loads: wind, waves and salt water shake masts and attack the welds of the foundations. At regular intervals, these welds are extensively studied by divers for defects. Now the robot should take over. And they should also be faster and more reliable.

Storm is picking up: Offshore wind turbines are exposed to enormous forces from wind and waves. Therefore, the welds must be checked frequently. This happens under water very expensive by divers. Now Fraunhofer researchers have developed a robot and a sensor system that could take on this task.

No more snow chaos on motorways? No flight cancellations due to snowfall? No frozen bridges? An invention by the American engineer Chris Tuan could ensure that roads, paths and bridges in the future always remain dry and ice-free. At the same time, the material can even be used to counter espionage.

Winter at Frankfurt Airport: at present, the runways and traffic routes still have to be freed of ice and snow with machines and sometimes by hand. An American engineer has now developed a conductive concrete that warms up.

Happiness in bad luck for the ski racer Matthias Mayer: During his fall in Val Gardena on Saturday, a ski airbag for the first time prevented the worst injuries. Read here how the airbag works for the ski slope.

Flight of the ski racer Matthias Mayer to the Innsbruck hospital: Mayer crashed heavily at the World Cup downhill in Val Gardena and broke two thoracic vertebrae. For the first time in a World Cup race an airbag was triggered, which protects the upper body. Probably Mayer would have suffered even worse injuries.

In order to withstand the rigors of operation for years on highly stressed components, the surfaces are hardened with carbon and nitrogen atoms. With a new procedure, this is faster and better. This facilitates the further development of drives.

In the beginning was the fire: working on the blast furnace is a first step in steel production. The material and its processing continues to be researched. Now, the Karlsruhe Institute of Technology has developed a new method for hardening steel.
