In April, Australian researchers delivered a cutting blow to hairy male hipsters – their research found that beards are only attractive to women if they’re a rarity. The bald truth is that, when too many people conform to bristly non-conformism, it quickly becomes a turn-off. But there was good news for men who’ve resisted rejecting their razors in the current sea of beards – a smooth chin is considered more attractive when everyone else is sporting facial fuzz. The researchers said their findings reflect patterns seen in other animals – females tend to find rare features attractive in potential mates.
July brought abominable news for mythical animal fans; a detailed analysis of 30 tufts of hair from around the world thought to be from yetis, bigfoot and other extraordinary ape-like creatures showed they all came from ordinary, decidedly non-mythical animals. Ten samples turned out to be bear hair, while others were from dogs, cows, horses, and there was even one from a person. However, some of the results were out of the ordinary; two of the samples – from the mountains of India and Bhutan – didn’t match any living animals, but did match an extinct species of polar bear thought to have died out around 40,000 years ago.
Watch out under the mistletoe this year – in November, Dutch researchers took bacterial samples from the mouths of 21 canoodling couples and found that a ten second snog transfers as many as 80 million bacteria. They also noticed that partners who kiss nine times a day or more share similar communities of mouth microbes. But don’t be too grossed out – a regular game of tonsil tennis is good for our health, priming our immune systems to fight off any infections we pick up from our partners later, they say.
Scientists announced the first example of an animal where the female has a ‘penis’ and the male a ‘vagina’ – the bizarre Brazilian cave insect Neotrogla – in April. During sex, the aggressive female penetrates a vagina-like opening on the male’s back with a barbed penis-like organ, grappling the couple together. You might want to cross your legs for this next gory detail – the pair bond so tightly that, when separated by the scientists, the male’s body ripped apart, leaving his genitals behind. And, to top it all off, these females put male lovers to shame – mating can last up to 70 hours. I think we all know who wears the trousers in that relationship.
In February, German doctors who were stumped by a tricky case were struck by some remarkably familiar symptoms while watching an episode of US TV medical drama ‘House’. Their patient was suffering from seemingly inexplicable severe heart failure, as was the fictional physician’s. The medical misanthrope diagnosed his patient as suffering from cobalt poisoning caused by a metal hip implant, and when the real-life doctors replaced their own patient’s metal hip implant with a ceramic one, he rapidly recovered.
WOW. An interesting year. Stay tuned later in the week for PART 2!
