Around 80 per cent of modern thoroughbred racehorses have in their pedigree the 18th century horse Eclipse, which went its entire racing career unbeaten. 200 years later the question of what makes a fast racehorse still perplexes trainers and racing fans but researchers at The Royal Veterinary College may have found the answer to this and other questions on animal locomotion.
The research, funded by the Biotechnology and Biological Sciences Research Council (BBSRC), has combined data about the length, shape and structure of horses with analysis of horses in the field to develop mathematical and computer models of horse movement. Using the models the research team can then build ’theoretical limbs’ on a computer and use them to test answers to questions on not only why Eclipse was so fast but also why horses can remain balanced when each leg is off the ground for 80 per cent of the ground during gallop and what limits a horse’s maximum gallop speed.
Dr Alan Wilson, leader of the research group, said, "A horse’s leg resembles a pogo stick that uses energy stored in the muscles and tendons to propel the animal forwards and upwards. We have found that the stiffer a horse’s leg restricts how quickly it can transmit force to the ground and bounce back up again and also increases the chances of injury. The team has also found that fast horses can bring their legs forward quickly in preparation for the next stride but that this is more difficult and therefore slower for large and long-legged horses."

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.
