Nine of 16 trials found that extracts from the aerial parts of the plant Echinacea purpurea could reduce the symptoms of colds in adults if started early enough. One further trial showed a trend towards this effect. This was the conclusion of an updated systematic Review published in the latest update of The Cochrane Library.
While there are signs of promise, the Authors sound a note of caution. “Our systematic review found some evidence that preparations based on the aerial part of Echinacea purpurea might be effective for the early treatment of colds in adults, but results are not fully consistent,” says lead author Dr Klaus Linde, who works at the Centre for Complementary Medicine Research in Munich, Germany.
Preparations of the plant are widely used in some European countries and in North America for common colds.

At the 2018 ILA Berlin Air Show from April 25–29, the Fraunhofer Institute for Laser Technology ILT is showcasing extreme high-speed Laser Material Deposition (EHLA): A video documents how for metal components that are highly loaded, EHLA has already proved itself as an alternative to hard chrome plating, which is now allowed only under special conditions.

At the ILA Berlin, hall 4, booth 202, Fraunhofer FHR will present two radar sensors for navigation support of drones. The sensors are valuable components in the implementation of autonomous flying drones: they function as obstacle detectors to prevent collisions. Radar sensors also operate reliably in restricted visibility, e.g. in foggy or dusty conditions. Due to their ability to measure distances with high precision, the radar sensors can also be used as altimeters when other sources of information such as barometers or GPS are not available or cannot operate optimally.
Drones play an increasingly important role in the area of logistics and services. Well-known logistic companies place great hope in these compact, aerial...
