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."

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
Theoretical physicists propose to use negative interference to control heat flow in quantum devices. Study published in Physical Review Letters
Quantum computer parts are sensitive and need to be cooled to very low temperatures. Their tiny size makes them particularly susceptible to a temperature...
Let’s say the armrest is broken in your vintage car. As things stand, you would need a lot of luck and persistence to find the right spare part. But in the world of Industrie 4.0 and production with batch sizes of one, you can simply scan the armrest and print it out. This is made possible by the first ever 3D scanner capable of working autonomously and in real time. The autonomous scanning system will be on display at the Hannover Messe Preview on February 6 and at the Hannover Messe proper from April 23 to 27, 2018 (Hall 6, Booth A30).
Part of the charm of vintage cars is that they stopped making them long ago, so it is special when you do see one out on the roads. If something breaks or...
