| Two groups of scientists have developed tests for gene doping in what the World Anti-Doping Agency hailed on Friday as a major breakthrough in fighting the next frontier in cheating in sports. |
Scientists in Germany said they have come up with a blood test that can provide "conclusive proof" of gene doping, even going back as far as 56 days from when the doping took place.
And a US-French research team has devised its own method for detecting genetic doping in muscles.
The discoveries raise the possibility that a valid gene-doping test can be implemented across the sports world by the 2012 London Olympics.
