Scientists reveal the world’s thinnest hologram that emerges from your phone

The day when holograms can pop out of electronic devices like smart phones, computers and TVs has moved a step closer thanks to the creation of the world’s thinnest hologram.

In a paper published in the journal Nature Communications, an Australian-Chinese research team led by professor Min Gu of RMIT University revealed a nano-hologram that is simple to make, can be seen without 3D goggles and is 1000 times thinner than a human hair.

Interactive 3D holograms have been often seen in science fiction and RMIT University’s version would look similar to the hologram that shoots out of R2-D2 as he delivers Princess Leia’s message in Star Wars: Episode IV.

“Conventional computer-generated holograms are too big for electronic devices but our ultrathin hologram overcomes those size barriers,” Gu said.

“From medical diagnostics to education, data storage, defence and cyber security, 3D holography has the potential to transform a range of industries and this research brings that revolution one critical step closer.”

Conventional holograms work by modulating phases of light to give the illusion of three-dimensional depth. But to generate enough phase shifts, those holograms need to be at the thickness of optical wavelengths.

However, The RMIT research team, broke this thickness limit by using a 25 nanometre hologram based on a topological insulator material.

The result is a hologram that is capable of leaping from devices’ screens regardless of their size.

“Integrating holography into everyday electronics would make screen size irrelevant – a pop-up 3D hologram can display a wealth of data that doesn’t neatly fit on a phone or watch,” said Gu.

Next, the research team hopes to shrink the hologram’s pixel sixe as well as making the hologram work on different surfaces.

“The next stage for this research will be developing a rigid thin film that could be laid onto an LCD screen to enable 3D holographic display,” said the paper’s co author Dr Zengyi Yue.

“This involves shrinking our nano-hologram’s pixel size, making it at least 10 times smaller.

“But beyond that, we are looking to create flexible and elastic thin films that could be used on a whole range of surfaces, opening up the horizons of holographic applications.”

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.
