Ever wondered why you aren’t able to swat a fly? The fly’s secret in avoiding death in this way lies in its decision to jump rather than to fly out of the way. “This kind of low-power decision-making could be of interest to those building autonomously navigating robots", according to Gwyneth Card of the California Institute of Technology, who will be presenting her work on triggered escape response at the Society for Experimental Biology Annual Main Meeting in Barcelona, on Wednesday 13th July [session A7.15].
To investigate responses in Drosophila melanogaster, she performed experiments dropping black discs from different angles, on a collision course with the flies. Capturing the responses on video, she showed that flies escaped by means of jumping in a forward fashion and directly away from the object, in addition to using their wings. Her results suggest that signals in the brain transferred via the ‘giant fibre pathway’, initiate a “take-off” sequence, involving stretching of the legs and depression of the wings that can move the fly in a specific direction.
Previous studies did not detect directional jumping1, but observations were made in conjunction with non-directional stimuli such as switching lights on and off. Card’s results imply that there could be a simple neural solution that "answers" questions within what is essentially a reflex arc.

In a recent publication in the renowned journal Optica, scientists of Leibniz-Institute of Photonic Technology (Leibniz IPHT) in Jena showed that they can accurately control the optical properties of liquid-core fiber lasers and therefore their spectral band width by temperature and pressure tuning.
Already last year, the researchers provided experimental proof of a new dynamic of hybrid solitons– temporally and spectrally stationary light waves resulting...

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.
Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...
The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.
Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.
An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.
Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...
