Dogs’ excellent sense of smell can help us find people after a disaster or sniff out a landmine. Now researchers at the University of Waikato are training dogs to detect lung cancer using breath and saliva samples.
Many lung cancer patients only see their doctor when they experience symptoms, but by this stage the disease may be advanced. Researcher Tim Edwards hopes the findings may contribute to the development of a scent-detection system for early lung cancer screening.
And the discovery of a huge lake of liquid water under the southern icecap of Mars has scientists excited, as Jonti Horner writes, and again raises the question of whether life exists on the red planet.
