Over millions of years of evolution, nature has worked out solutions to many problems. Humans have arrived late in the day and pinched them. For example, Velcro was invented<\/a> after a Swiss engineer marvelled at the burdock burrs that got stuck to his dog\u2019s fur; the idea for robotic arms came from the motion and gripping ability of elephant trunks and the front of Japan\u2019s bullet trains were redesigned to mimic a kingfisher\u2019s streamlined beak, reducing the sonic boom they made exiting tunnels.<\/p>\n

There are different types of mimicry, the most straightforward is the simple idea of copying something that exists in nature. Buildings are an obvious example, as outlined by research published in Nature<\/a>. The Beijing national stadium is inspired by a bird\u2019s nest, the Lotus Temple in India is shaped, unsurprisingly, like a lotus and the Palm Jumeirah in Dubai is shaped like a palm tree.<\/p>\n

Next, there is mimicry of both design and function, such as camouflage dress being inspired by nature\u2019s ability to disguise itself. Then there is mimicry solely for function, for example the blades in noiseless fans are modelled on whale fins and gecko tape on the lizard\u2019s sticky feet.<\/p>\n<\/div>\n

\n

Our ability to copy nature is becoming more sophisticated thanks to advances in nanotechnology. The atomic force microscope, invented in the 1980s, uses a probe with a very sharp tip 1,000 times smaller than a width of hair and can closely scan sample materials. This has facilitated the development of biomimicry, which allows better replication of natural materials than ever before.<\/p>\n

Saurav Goel, a professor in manufacturing at London South Bank University, is working to engineer materials that decompose, as sustainable alternatives to ones currently being used. \u201cPlastics, glass, cement and alloys are common engineering materials and their recycling consumes a lot of energy. It means that their natural decomposition will take several decades. This is a primary roadblock to sustainability,\u201d he says.<\/p>\n

His team is trying to replicate dragonfly wings<\/a>, which are naturally antibacterial, for use in artificial body parts because they could be more hygienic than current materials. His aim is to create a \u201cbio-robot\u201d in the next 50 years which has soft tissues that resemble those of a human. \u201cTo us, our human body is the perfect biological machine,\u201d he says.<\/p>\n<\/div>\n

Five cool ideas from nature for the future<\/h2>\n

1. Scientists have long been impressed at how well mussels cling to rocks underwater. Now, they are working out how to replicate their sticky proteins<\/a> to create a non-toxic glue that instantly sticks materials together, even underwater. It could be used to close wounds after surgery.<\/p>\n

2. Watching how ducks swim in a row is providing clues to shipping goods around the world<\/a> in more energy efficient ways. When a duckling finds the \u201csweet spot\u201d behind its mother, something called \u201cdestructive wave interference\u201d occurs: instead of the drag holding the duckling back, it actually pulls it forward so it uses less energy to paddle along. Other ducklings in the line benefit too. If ships travelled as part of \u201cwater-trains\u201d they could carry more cargo with no additional fuel.<\/p>\n<\/div>\n

3.<\/strong> Plant roots are able to selectively suck up water and specific nutrients needed for growth. Scientists are trying to mimic them to create better water purification<\/a> techniques.<\/p>\n

4.<\/strong> The chameleon\u2019s colour-changing skin contains little crystals, which reflect light differently depending on how big they are, or how they are arranged \u2014 to change colour they simply tense or relax their skin. Scientists are working out how to copy the way they adjust their colours based on their environment to make artificial \u201csmart skins\u201d<\/a> which could be used as camouflage or signalling over long distances.<\/p>\n

5.<\/strong> Plants produce food by photosynthesis, and when they do this they suck carbon dioxide out of the atmosphere. For decades, scientists have been trying to replicate this process as a way to produce energy and tackle the climate crisis. Researchers in California<\/a> have now managed to turn carbon dioxide into ethanol (which can be used as fuel) using a makeshift solar-powered cell.<\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
