As the Cheltenham Festival gets under way researchers reveal that a great racehorse is more than just quick footed

15.03.2006


The first day of racing at the Cheltenham Festival, the Olympics of steeplechasing, gets under way today. There will be many betting tips offered over the next few days, and advice given on how to back a winner. However, Royal Veterinary College researchers reveal that a great racehorse is more than just quick footed - it must also be rather average.



The Royal Veterinary College research reveals the secret to what makes a fast thoroughbred. Some 80 percent of modern thoroughbred racehorses have in their pedigree the undefeated 18th Century horse Eclipse – now a racing legend. Yet, until recently, scientists haven’t been able to figure out what makes some horses faster than others.
The work combined what was known about Eclipse with data on the shape and structure of modern horses to develop mathematical and computer models of their movement.

Using portraits of Eclipse and contemporary accounts of the horse running the researchers reconstructed one of its legs and have discovered that its legendary speed may have been due to its ‘averageness’.



The research involved analysing Eclipse’s skeleton to develop models of horse movement. Using the models the research team built ‘theoretical limbs’ on a computer and tested 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 of the Royal Veterinary College 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. 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.”

Dr Wilson added: “Analysis shows that Eclipse’s body shape and everything about him seems to have been right in the middle of the normal range, suggesting that all the factors for speed were perfectly matched.”

Im Focus: LaserTAB: More efficient and precise contacts thanks to human-robot collaboration

At the productronica trade fair in Munich this November, the Fraunhofer Institute for Laser Technology ILT will be presenting Laser-Based Tape-Automated Bonding, LaserTAB for short. The experts from Aachen will be demonstrating how new battery cells and power electronics can be micro-welded more efficiently and precisely than ever before thanks to new optics and robot support.

Fraunhofer ILT from Aachen relies on a clever combination of robotics and a laser scanner with new optics as well as process monitoring, which it has developed...

Im Focus: The pyrenoid is a carbon-fixing liquid droplet

Plants and algae use the enzyme Rubisco to fix carbon dioxide, removing it from the atmosphere and converting it into biomass. Algae have figured out a way to increase the efficiency of carbon fixation. They gather most of their Rubisco into a ball-shaped microcompartment called the pyrenoid, which they flood with a high local concentration of carbon dioxide. A team of scientists at Princeton University, the Carnegie Institution for Science, Stanford University and the Max Plank Institute of Biochemistry have unravelled the mysteries of how the pyrenoid is assembled. These insights can help to engineer crops that remove more carbon dioxide from the atmosphere while producing more food.

Im Focus: Highly precise wiring in the Cerebral Cortex

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.

The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...

Im Focus: Ultrafast snapshots of relaxing electrons in solids

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!

When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
