Scientists overturn idea racehorses can't get any faster

Racehorses are reaching faster and faster speeds, scientists have found, overturning research which suggested they had reached their galloping limit.

A team from the University of Exeter studied a total of 616,084 races run by more than 70,000 horses, with a broader focus on sprint races.

Previous research, which suggested speeds had reached a plateau, had largely concentrated on a small number of middle- to long-distance races.

It is not yet known whether the faster pace is down to breeding, better training, better jockeys, or a combination of these.

Researcher Dr Patrick Sharman said:

There has been a general consensus over the last 30 years that horse speeds appeared to be stagnating.

Our study shows that this is not the case and, by using a much larger dataset than previously analysed, we have revealed that horses have been getting faster. Interestingly, both the historical and current rate of improvement is greatest over sprint distances.

The challenge now is to find out whether this pattern of improvement has a genetic basis.

Fish genetically mutated by Cornish mining

Research at Exeter University has linked the evolution of fish to pollution from Cornwall's mining boom.

Scientists have found that pollution from historic mines in the South West has "severely affected" the genetic diversity of local populations of brown trout.

The report highlights the difference between so-called clean rivers like the Camel and the Fal, with more contaminated rivers such as the Hayle.

Tin mine clean-up could reap rewards

Researchers at Exeter University are hoping to use algae to clean up water from a tin mine.

The project is taking place at Wheal Jane in Cornwall. Scientists hope the work will have extra benefits in that the algae will harvest precious metals at the same time.
