A remarkable robot, capable of solving a Rubik’s cube single-handedly, has demonstrated just how far robotics has advanced - but at the same time, experts say, how far we still have to go.OpenAI’s system used a computer simulation to teach the robot hand to solve the cube, running through routines that would take a single human some 10,000 years to complete.Once taught, the robot was able to solve a cube that had been slightly modified to help the machine tell which way up it was being held.Completion time varied, the research team said, but it generally took around four minutes to complete the task.Using machine-learning and robotics to solve a Rubik’s cube has been achieved before. Notably, in March 2018, a machine developed by engineers at MIT managed to solve a cube in just 0.38 seconds.What’s significant with OpenAI’s effort is the use of a multi-purpose robot, in this case a human-hand-like design, rather than a machine specifically designed to … [Read more...] about Robot hand solves Rubik’s cube, but not the grand challenge

A Viagra user says he is now impotent after doctors 'mutilated' his penis to fix his 'month-long' erection. Nat Thind, 26, bought Viagra over-the-counter in June, having previously used the drug several times in the past without any issues. But the electrician rushed straight to hospital when his erection wouldn't subside and became painful, a condition known as priapism. Mr Thind, from Hampshire, claims doctors tried a number of methods to relieve him of his erection over three days - but none worked. Eventually, surgery using a blade to drain the blood was the only option. But Mr Thind claims doctors 'didn't really know what they were doing'. Mr Thind's erection finally went away naturally, but he has been left with possible permanent damage. Nat Thind, 26, bought a Viagra pill over the counter in June and now says he is impotent after doctors 'mutilated' his penis to fix a month-long erection Mr Thind, from Hampshire, claims doctors tried a number of methods … [Read more...] about Viagra user says his ‘month-long’ erection left him impotent after doctors ‘mutilated’ his penis to fix side effect caused by the drug

Every day, salmon farmers across the world walk into steel cages – in the seas off Scotland or Norway or Iceland – and throw in food. Lots of food; they must feed tens of thousands of fish before the day is over. They must also check if there are problems, and there is one particular problem they are coming across more and more often. Six months ago, I met one of these salmon farmers, on the Isle of Skye. He looked at me and held out a palm – in it was a small, ugly-looking creature, all articulated shell and tentacles: a sea louse. He could crush it between his fingers, but said he was impressed that this parasite, which lives by attaching itself to a fish and eating its blood and skin, was threatening not just his own job, but could potentially wipe out a global multibillion-dollar industry that feeds millions of people. “For a wee creature, it is impressive. But what can we do?” he asks. “Sometimes it seems nature is against us and we are fighting … [Read more...] about Salmon farming in crisis: ‘We are seeing a chemical arms race in the seas’
