    WE ARE hallucinating all the time, according to neuroscience research. Our brains constantly tease comprehensible patterns out of a million sensory inputs – from buzzing bees to approaching animals. This isn’t reality, but a good prediction of what reality should be, informed by past experience. While it is an efficient way for the brain to generate the feeling of consciousness, it also means we are like passengers facing backwards on … More

    Was warfare responsible for the origin of complex civilisation?

    An effort to track global changes in human society over the past 10,000 years concludes that warfare drove an increase in social complexity – but others are unconvinced by the work

    Human societies have become incredibly big and complex over the past few thousand years, and they have done so primarily because of agriculture and warfare. That is the claim made by a large international collaboration that has spent more than a decade gathering data on the subject. But not everyone is convinced by these conclusions – or even by the starting assumptions.
    The way we live today is very different from the way humans have lived for most of our  history. For … More

    You're more likely to become friends with someone who smells like you

    We subconsciously sniff people when we first meet them and are more likely to become friends with those who have similar body odours to our own

    People with similar body odours are more likely to “click” and become instant friends, according to several experiments.
    When we first meet other people, we sometimes experience an “immediate strong click that makes us feel as if we have already been good friends for years”, says Inbal Ravreby at the Weizmann Institute of Science in Israel.
    She wondered if this may have something to do with body odour, because previous research has found that we subconsciously sniff each other on meeting – for example, by lifting our hand to our nose after shaking someone’s hand.Advertisement
    Ravreby and her colleagues recruited 20 pairs of same-sex, non-romantic friends – half female and half male – who said they clicked straight away on first meeting.
    An electronic nose – a device that senses the chemical components of odours – was used to sniff T-shirts that had been worn by each of the participants. The nose found that body odour was more similar between the friend pairs than between random pairs that were formed by shuffling the participants.
    A group of 25 independent adults who sniffed the participants’ T-shirts also reported that the friend pairs smelled more alike than random pairs did.

    Next, Ravreby and her colleagues recruited 17 people who had never met previously and used the electronic nose to analyse their body odours. Each individual then took turns playing a non-verbal game with other participants of the same sex.
    The results were consistent with the earlier experiments: the pairs that smelled more like each other were more likely to report feeling as if they clicked during this game.
    The findings makes sense because research shows that we tend to become friends with people who are like us, for example, in terms of age, ethnicity, education, religion, physical appearance, personality and values, says Ravreby.
    Other mammals also use smell to help decide who is friend or foe, such as dogs that sniff each other’s rear ends when they meet in a park, she says.
    In contrast, heterosexual people appear to be attracted to members of the opposite sex who smell different to them. One study, for example, has found that women were more attracted to odours of men who had different immune genes to them, possibly because their pairing would produce offspring with stronger immune systems.

    The Facemaker review: A powerful portrait of plastic surgery's pioneer

    Lindsey Fitzharris’s biography of Harold Gillies, who became the world’s pre-eminent specialist in plastic surgery during the first world war, depicts a forward-thinking, gifted man

    By Oliver-James Campbell

    AROUND 40 million people were wounded or killed in the first world war. “For the first time… Europe’s military technology had wildly surpassed its medical capabilities,” writes historian Lindsey Fitzharris in her informative book, The Facemaker.
    Fitzharris introduces us to New Zealand-born ear, nose and throat doctor Harold Gillies. By 1917, he had become the world’s pre-eminent specialist in plastic surgery, developing techniques still used today like the “bishop’s mitre flap” for the nose, or the “tubed pedicle” for severe burns.
    Plastic surgery in the 19th century was crude, with masks … More

    How to reap the benefits of crop rotation in your own garden

    Even the smallest vegetable patch can benefit from the principles of crop rotation, says Clare Wilson

    WHEN I finally reached the top of my local area’s long waiting list for allotments, one aspect of vegetable growing that seemed daunting to me was crop rotation. This means dividing your ground into a few different patches and changing where you grow your plant varieties year on year. The intention is to reduce the build-up of pests and diseases, while also improving soil fertility.
    Any guidance I could find on doing this seemed complicated, plus it required more ground than I initially had, since most of the new plot was badly overgrown. But as I learned, you don’t always … More
