Tiger Woods probably wants to look away at this point

Bad news here for wannabe Casanovas: an Australian study has concluded that women can spot a dirty cheater just by looking at his face.

According to a paper in Biology Letters, the team led by Gillian Rhodes at the ARC Centre of Excellence in Cognition and its Disorders at the University of Western Australia in Perth, tended to judge faithfulness based on how “masculine-looking” the dude was. Whether the guys were deemed attractive or not was immaterial.

Researchers then compared the judgements (of 34 women) with the actual self-reported histories of the 189 men and women involved and found women called it better. That said, the women didn’t have a clue when it came to discerning women cheaters.

The 34 men who took part were rubbish, basing their judgement on whether the women were feminine and attractive. Some wishful thinking was probably involved, we reckon.

Meanwhile in Austria, researchers have noted that dogs can sniff out lung cancer. The test saw dogs achieve a 70 per cent success rate identifying cancer from 120 breath samples. Scientists believe that this will assist in developing an electronic nose which can detect early stage lung cancer. Great work, mutts!

And great work, Chinese boffins, too, if a little stinky on this particular occasion. A new study published in the journal Nature Methods postulates an alternative to the controversial embryonic stem cell harvesting. Stem cells have the ability to grow into most other kinds of cells in the human body, making them potentially useful for neurodegenerative diseases such as Parkinson’s. Aside from the morality of their harvesting, embryonic stem cells also do come with the risk of developing tumours.

So the researchers at China’s Guangzhou Institutes of Biomedicine and Health, part of the Chinese Academy of Sciences, decided to reprogramme cells from skin and blood – successfully. However, they found, there is a much more accessible source for the basic cells they need to complete this process and that is urine. Researchers say, rightly, that it’s a heck of a lot easier to get a kid to give a urine sample than a blood sample. And so science moves on its zigzag path to a better future.
