Australian scientists have developed a new system for catching drug cheats in sport which they say could be available in time for the 2020 Tokyo Olympics.
Scientists at the Australian National University in Canberra have worked with a commonly occurring bacterial enzyme that detects a range of drugs not regularly tested for.
Researchers said it could detect drugs in an athlete's system well after the point at which other methods could not pick them up.

ANU chemistry researchers have been awarded for their work on an important milk protein, which is leading to a better understanding of the biochemical processes underlying diseases such as Alzheimer's and Parkinson's diseases.

International research led by The Australian National University (ANU) has found how plants, such as rice and wheat, sense and respond to extreme drought stress, in a breakthrough that could lead to the development of next-generation drought-proof crops.
Lead researcher Dr Kai Xun Chan from the ANU Research School of Biology said the team discovered an enzyme that senses adverse drought and sunlight conditions, and how it works from atomic to overall plant levels.
