Scientists create super stretchy, strong and sustainable artificial spider silk that works like a “miniature bungee cord”

A team of architects and chemists from the University of Cambridge have created a super stretchy, strong and sustainable artificial spider silk.

Spider silk is one of nature’s strongest materials, and scientists have long been attempting to mimic its properties for a range of applications, with varying degrees of success.

Described as a  “miniature bungee cord” because of its ability to absorb large amounts of energy, the new artificial spider silk is ‘spun’ from a material that is 98% water and could be used to make textiles and sensors.

The technique used to create the new silk improves upon earlier methods of making synthetic spider silk because it doesn’t require high-energy procedures or extensive use of harmful solvents, and it could substantially improve methods of making synthetic fibres of all kinds, since other types of synthetic fibres do rely on high-energy, toxic methods.

“Although our fibres are not as strong as the strongest spider silks, they can support stresses in the range of 100 to 150 megapascals, which is similar to other synthetic and natural silks,” said Dr Darshil Shah from Cambridge’s Department of Architecture.

“However, our fibres are non-toxic and far less energy-intensive to make.”

The fibres designed by the Cambridge team are “spun” from a material constructed from naturally available materials called hydrogel, which is 98% water and 2% silica and cellulose.

By combining the different components, the scientists are able to pull long spider silk-like fibres from the gel.

After roughly 30 seconds, the water evaporates, leaving extremely thin threads behind – a few millionths of a metre in diameter – which are both strong and stretchy.

The strength of the fibres exceeds that of other synthetic fibres, such as cellulose-based viscose and artificial silks, as well as natural fibres such as human or animal hair.

In addition to its strength, the fibres also show very high damping capacity, meaning that they can absorb large amounts of energy, similar to a bungee cord.

There are very few synthetic fibres which have this capacity, but high damping is one of the special characteristics of spider silk. The researchers found that the damping capacity in some cases even exceeded that of natural silks.

“We think that this method of making fibres could be a sustainable alternative to current manufacturing methods,” said Shah. The researchers plan to explore the chemistry of the fibres further, including making yarns and braided fibres.

Scientists implant device to boost human memory

Scientists have enhanced human memory for the first time with a “memory prosthesis” brain implant. The team behind the device say it can boost performance on memory tests by up to 30%, and a similar approach may work for enhancing other brain skills, such as vision or movement.

Astronomers discover Earth-sized world 11 light years away

A planet, Ross 128 b, has been discovered in orbit around a red dwarf star just 11 light years from the Sun. The planet is 35% more massive than Earth, and it likely exists at the edge of the small, relatively faint star's habitable zone even though it is 20 times closer to its star than the Earth is to the Sun.

An algorithm can see what you've learned before going to sleep

Researcher fed the brain activity from sleeping subjects to a machine learning algorithm, and it was able to determine what the subject had learned before falling asleep. In other words, an algorithm was able to effectively ‘read’ electrical activity from sleeping brains and determine what they were memorising as a result.

Elon Musk unveils Tesla Truck and Tesla Roadster

Elon Musk has unveiled the long-anticipated 'Tesla Semi' – the company's first electric articulated lorry. The vehicle has a range of 500 miles on a single charge, and will go into production in 2019. Unexpectedly, Tesla also revealed a new Roadster, which will have a range of close to 1,000km (620 miles) on a single charge and will do 0-100mph in 4.2 seconds.

Arrivo plans to build 200mph hyperloop-lite track

Arrivo, the company founded by former Hyperloop One engineer Brogan BamBrogan, has announced a partnership with Colorado’s Department of Transportation. Arrivo will now build a magnetised track to transport existing vehicles, cargo sleds and specially designed vehicles alongside preexisting freeways at 200mph in the city of Denver.

Boston Dynamics' Atlas robot can now do backflips

It's been a busy week for Boston Dynamics, first the company revealed it SpotMini robot dog was getting an upgrade, and now the company has shared a video of its Atlas humanoid robot leaping from platforms and doing a backflip. It seems like an obvious thing to say, but it's not easy to make a robot do a backflip, so how Boston Dynamics has managed it is anyone's guess.

The all new Factor Magazine is here – your guide to how today, tomorrow and beyond are being shaped

Guess who’s back, back again.

It’s been a few months, but Factor has returned with a bigger and better format, bringing the same future news and discussion, but on a platform that you can read on any device.

We’ve been working towards this for a long, long time: this is how we’ve always wanted the magazine to look, and we’re so happy to share this with you. It can be viewed on any web browser, on anything from a mobile to a monster PC, and if you’re on a desktop or laptop, click the button in the bottom right-hand corner for the ultimate shiny reading experience. A digital magazine has never looked this good. Probably.

Unfortunately that means no more iPad app, but as you can easily read the magazine from an iPad web browser, we hope you’ll agree that what we’ve gained is so much better than what’s been lost.

So anyway, here it is: the Winter 2017 issue of Factor, the first issue of the quarterly version of the magazine.

In case any of you are worrying about us publishing the magazine quarterly, trust us you don’t need to. We’ve produced the biggest issue of Factor ever, so packed with futuristic awesomeness, that we’ve had to divide it into three sections: Today, Tomorrow and Beyond.

Today deals with the futuristic present, as much of what we think of as ‘the future’ already exists today. We look at how humanoid robots are being employed as co-workers, hear from the legendary Richard Stallman about the vanishing state of privacy and discover how automation is already taking jobs. Plus, we take a light hearted look at the futuristic world of Mr Tesla, Elon Musk, and provide our festive present suggestions in a bumper futuristic gift guide.

Moving on to Tomorrow, and it’s all about the world of the next few decades, as technologies that are in development now reach fruition and seep into our everyday lives. We consider how flying cars are inching towards reality, with a look at both Lilium and the newly announced UberAir, and find out how driverless delivery may be the first true instance of the self-driving future.  Plus, we also look at the Christmas dinners of the future, because why the hell not.

Finally, in Beyond we look at the way-out future that many of us probably won’t live to see, but is supremely cool to think about. We ask leading futurists to predict what’s in store in the 22nd century – not the most positive of pictures, unfortunately – and consider what jobs will remain in a post-automation world. Plus, we look at the potential first homes of the human race beyond the solar system, and check out how asteroid mining is set to shape off-earth development.

Take a look, and if you like what you see and read, please share the magazine with your friends, or tell us what you think. This is a completely free magazine, with not an ad in sight, so it’s always good to know that it’s worth the effort.
