<p>The worm Caenorhabditis elegans has just 300 neurons and around 1,000 cells - and now a robot has been created that mimics the actions of this simple organism. The OpenWorm team from California is making a 'digital' worm. Their project is recreating the neurons and cells in C. elegans, the simplest organism we know of. By making a digital worm the team hope to create artificial life. They have implanted the digital 'mind' of the worm into a Lego machine.</p>

<div>The OpenWorm team from California is making a 'digital' worm. Their project is recreating the neurons and cells in C. elegans, the simplest organism we know of. By making a digital worm the team hope to create artificial life. They have implanted the digital 'mind' of the worm into a Lego machine.&nbsp;The OpenWorm project, a global effort including researchers from the US and UK, is attempting to create the world&rsquo;s first digital animal.&nbsp;Earlier this year they ran a successful Kickstarter campaign to fund the creation of a worm you can download onto your computer.</div>

<div>The Caenorhabditis elegans nematode is only around 0.04 inches (1mm) in length, is transparent and feeds on bacteria, such as E. coli. It moves around in water at a rate of about 0.04 inches (1mm) per second.&nbsp;Despite being composed of just 1,000 cells, the creature exhibits relatively advanced behaviour such as finding a mate and avoiding predators.&nbsp;The worm has been the focus of huge amounts of research and was the first multi-celled organism to have its entire genome mapped.&nbsp;And they have also created a robot that mimics the actions of a real-life worm.&nbsp;C. elegans is one of the simplest forms of life we know, thanks to its limited neurons and cells, and thus researchers have been able to accurately map its body.&nbsp;The worm, though simple, contains 80 per cent of the same genes as humans and can be studied as a more basic version of complex life.&nbsp;With a brain, stomach and bodily functions, the worm has provided scientists with a way to study life on a much smaller and more manageable scale.&nbsp;In this latest project the researchers mapped the entire physiology of a C. elegans organism.&nbsp;They then recreated the worm&rsquo;s brain, cells and more in digital form, complete with neurons &lsquo;firing&rsquo; to make decisions.&nbsp;Scientists re-create worm brain with Lego machine</div>

<div>In a recent comment on futrology site Edge, SpaceX and Tesla Motors chief Elon Musk warned of the dangers of artificial intelligence. &nbsp;In his comment he feared that the risk of &lsquo;something seriously dangerous happening&rsquo; could be in as few as five years.&nbsp;Although he doesn&rsquo;t go into detail, he alludes to &lsquo;digital superintelligences&rsquo; and internet bots as being among the potential problems facing humanity.&nbsp;In the comment he says the pace of progress in AI is &lsquo;incredibly fast&rsquo;.&nbsp;He continued: &lsquo;I am not alone in thinking we should be worried.&nbsp;&lsquo;The leading AI companies have taken great steps to ensure safety.&nbsp;&lsquo;They recognise the danger, but believe that they can shape and control the digital superintelligences and prevent bad ones from escaping into the internet. That remains to be seen&hellip;&rsquo; &nbsp;The ultimate goal of the project is to give people access to their own digital worm called WormSim to study on their computers through the OpenWorm project.&nbsp;Following the successful Kickstarter campaign, this should be available next year.&nbsp;But they have also inserted the artificial brain of the worm into a Lego machine, specifically a Lego Mindstorms EV3 robot.&nbsp;By recreating the 302 neurons and 959 cells of this tiny nematode worm, the robot can then be left to &lsquo;mimic&rsquo; the actions of a real-life worm.&nbsp;This means it moves around, runs into obstacles like walls and also turns.&nbsp;The robot is very basic for now, and does not possess the ability to perform more complex functions such as eating.&nbsp;It&rsquo;s an important step, though, to creating artificial life that can think for itself.&nbsp;While this worm is a very basic form of life, it may be a precursor to making much more complex animals.&nbsp;This will be a huge undertaking, though - even a mouse has 22 million neurons in its brain.&nbsp;&lsquo;The mere act of trying to put a working model together causes us to realise what we know and what we don't know,&rsquo; John Long, a roboticist and neuroscientist at Vassar College in New York State, told New Scientist.</div>
