PINPRICK tests for blood sugars in diabetics could become a thing of the past, after a breakthrough by scientists in South Korea who have developed a sweat sensor.
The team from the Seoul National University don't need a gym-soaked T-shirt, reports the BBC, but rather just one thousandth of a millilitre of perspiration to measure blood sugar via the gadget which also analyses sweat humidity and acidity to come up with a result.
The electronics are encased in a porous layer (pictured) which allows the sweat to soak through, with trial results showing the results from the sensor "agree well" with those from blood tests.
archaeologists working on a site in northern Spain are thanking their lucky stars that Neanderthal Man had poor dental hygiene.
They have managed to figure out lots of interesting information on how our antecedents lived - by analysing DNA found in the tooth plaque of the former inhabitants of El Sidron Cave.
Intriguingly, the scientists from the University of Adelaide, South Australia and the University of Liverpool in the UK have concluded the Neanderthals possibly used plants to self-medicate, with DNA from poplar trees (a source of salicylic acid) and penicillium mould (used to make penicillin) found in the teeth.
