Only the third, which left him half-paralysed, prevents him climbing. Another Briton, Joe Simpson, still returns to the mountains, despite having almost died twice – once after breaking his leg descending a remote Chilean peak (an experience recounted in his best-seller Touching The Void), and again after snapping an ankle in a similar situation. Alan Hinkes was lucky to live last week after breaking his elbow in a fall into a crevasse while descending alone from Kanchengjunga, the third-highest mountain in the world. He says he’ll go back next year.You might wonder what keeps people like that returning They can’t usually put it into words All they know is that they feel an absence.
Jochen Hemmleb, a 28-year-old German climber and geologist, who organised the expedition which last year found the remains on Everest of George Mallory, put it best at a recent conference for climbers. They had been talking about how they wanted their non-climbing partners to enjoy their experiences, even if just vicariously “That’s fine,” said Hemmleb. “But let me ask you: what is there of their experiences which you take on board in the same way, that you want them to do with climbing?” Nobody answered.You can contact Jamie Andrew at jamie bennevis2000.fsnet.co.uk. Scientists think they have worked out how geckos walk on ceilings: it appears they use the one billion hair-like fringes, called setae, on their feet to produce a force that can attach them to the smoothest surfaces.

Kellar Autumn, who led a team from Lewis and Clark College, Portland, Oregon, whose findings appeared in the science journal Nature, suggested the discovery about the lizards could lead to new adhesives, although “engineering a structure as exquisite as the foot of the gecko is probably beyond human technology”.A common gecko’s foot has 500,000 setae, each a tenth the diameter of a human hair. Each seta splays into hundreds of finer, spatula-shaped structures which, at 0.3 microns (micrometres) long, are only 1,000 times bigger than the simplest atom, hydrogen.At such scales, an attractive force called Van der Waals comes into play when two small objects move together.
These can be very powerful: the scientists estimated that if a gecko stuck all the setae on one foot on to a surface, it would generate a force equivalent to 10 times atmospheric pressure.The final key to the gecko’s success is orientation of the setae, which point towards the heel: as the animal takes a step, the setae and spatulas are pushed against the surface and pulled backwards parallel to it, producing the best means of getting the microfilaments in ideal contact with the surface. They then take them off by lifting their feet up – rather like peeling off adhesive tape.. As a cure for post-natal depression it might not be the most obvious solution. But for one woman, the sight of Keith Chegwin prancing around au naturel on her television was enough to make her laugh for the first time in six months.
As a cure for post-natal depression it might not be the most obvious solution. But for one woman, the sight of Keith Chegwin prancing around au naturel on her television was enough to make her laugh for the first time in six months.
Chegwin, whose previous career highs have included Cheggers Plays Pop and knocking on strangers’ doors at 7am for The Big Breakfast, was hosting Naked Jungle on Channel 5. Everyone in the game show performed nude in a season of shows for Naturism Week Not all Channel 5 viewers were amused. One man lodged “an official complaint about Keith Chegwin’s ginger willy” which he found to be “one of the most disturbing things ever shown on British television”.The station logged 50 calls after the programme on Tuesday night. A spokesman said: “We had a call from one woman who thanked us for snapping her out of her post-natal depression.
