“Antelope Perfume” Keeps Flies Away From Cows

In Africa, tsetse flies transfer the sleeping sickness also to cattle. This leads to huge losses in milk, meat and manpower. The damage in Africa is estimated to be about 4.6 billion US dollars each year. Prof. Dr. Christian Borgemeister from the Center for Development Research (ZEF) at the University of Bonn and his colleagues from Kenya and the UK have developed an innovative way of preventing the disease. The scientists took advantage of the fact that tsetse flies avoid waterbucks, a widespread antelope species in Africa. The scientists imitated the smell of these antelopes. If the cattle were equipped with collars containing the defense agent, more than 80 percent of the cattle were spared from the feared infection. This research results are presented in "PLOS Neglected Tropical Diseases".

Real-time feedback helps save energy and water

Those who take long showers use a great deal of water and energy. Yet people who enjoy taking long showers do not usually realize to what extent they are damaging the environment. However, if a clever measuring system shows current consumption, this immediately leads to increased efficiency. The consumption information available on the display is incentive enough to reduce water and energy consumption when showering on average by 22 per cent. This was shown by a study conducted by the Universities of Bonn and Bamberg, as well as ETH Zurich. The results have initially been published online in the journal Management Science. The print edition will be published soon.

Climate change could trigger strong sea level rise

About 15,000 years ago, the ocean around Antarctica has seen an abrupt sea level rise of several meters. It could happen again. An international team of scientists with the participation of the University of Bonn is now reporting its findings in the magazine Nature Scientific Reports.
