Racing success in a headwind
At the Aeolus-Race 2014, the World Championship for Ventomobiles (headwind vehicles), the students from Team InVentus from the University of Stuttgart were able to successfully defend their second place from the previous year at the weekend. At this year’s edition of the race from 18th until 24th August in the Dutch town of Den Helder there were once again top-class competitors with nine vehicles from five nations.
The fastest vehicle that could drive directly against the wind with the wind from the surrounding area as a source of energy was the winner. In so doing it was not permitted to drive in a zig-zag style or to traverse like when sailing. Instead of this the teams had to drive directly in the direction of the headwind.
After the gratifying result from the last year, the students wanted to replicate this success and make their vehicle more reliable and quicker. On the basis of the theory learnt in the lectures, they developed the vehicle further and often worked until late into the night on new components.
Initial test runs on the race course directly at the sea confirmed the expectations of the vehicle and therefore there was already a replay of last year’s duel with the Canadian Team Chinook from Montreal on the very first official competition day. After four races respectively in strong winds, InVentus was slightly ahead of the team from Canada, that had to battle sensory problems.
On the next competition day, however, the Canadians were able to solve their problems. They benefitted from the superior hull aerodynamics of their vehicle and secured the victory. The Team InVentus from the University of Stuttgart followed in second place with nearly 80 percent of the wind speed and therefore improved on their performance from the previous year by around 25 percent. The Team “Baltic Thunder” from Kiel secured third place.
Prof. Po Wen Cheng from the Stuttgart Chair for Wind Energy was particularly pleased about the strong result: "The consistent implementation of the theory into practice and the passion with which the students worked on solving complex and interdisciplinary problems is impressive. The clear improvement once again of the vehicle compared to the previous year is also a product of the quality of the teaching at the University of Stuttgart as well as the good framework conditions also outside of the lecture hall."
Since the return of the team after a one year break in 2012, the University of Stuttgart has entered the most successful team from recent years in the Aeolus Race with two second places in a row. For next year the team is pursuing the great objective of driving as the first team faster than the wind. Initial ideas are already in place: among others the aerodynamics are to be improved and the vehicle sensor technology is to become more reliable.

The University of Würzburg has two new space projects in the pipeline which are concerned with the observation of planets and autonomous fault correction aboard satellites. The German Federal Ministry of Economic Affairs and Energy funds the projects with around 1.6 million euros.

Physicists from Saarland University and the ESPCI in Paris have shown how liquids on solid surfaces can be made to slide over the surface a bit like a bobsleigh on ice. The key is to apply a coating at the boundary between the liquid and the surface that induces the liquid to slip. This results in an increase in the average flow velocity of the liquid and its throughput. This was demonstrated by studying the behaviour of droplets on surfaces with different coatings as they evolved into the equilibrium state. The results could prove useful in optimizing industrial processes, such as the extrusion of plastics.
The study has been published in the respected academic journal PNAS (Proceedings of the National Academy of Sciences of the United States of America).

Researchers at King’s College London and the Wellcome Trust Sanger Institute in the United Kingdom have for the first time demonstrated a direct link between the Wbp2 gene and progressive hearing loss. The scientists report that the loss of Wbp2 expression leads to progressive high-frequency hearing loss in mouse as well as in two clinical cases of children with deafness with no other obvious features. The results are published in EMBO Molecular Medicine.
The scientists have shown that hearing impairment is linked to hormonal signalling rather than to hair cell degeneration. Wbp2 is known as a transcriptional...
