First new sound wave class in half a century to revolutionise stem cell therapy

A new class of sound wave has been developed for the first time in 50 years that looks set to revolutionise the use of stem cells in medical treatments.

Created by acoustics experts from RMIT University in Melbourne, Australia, the sound waves – known as “surface reflected bulk waves” – are gentle enough to manipulate stem cells without causing damage, something that has not previously been possible with sound waves.

The researchers have already used the technology to significantly improve the efficiency of an advanced nebuliser device developed at RMIT, which delivers medicine directly to the lungs.

“We have used the new sound waves to slash the time required for inhaling vaccines through the nebuliser device, from 30 minutes to as little as 30 seconds,” said study co-author Dr Amgad Rezk, from the Micro/Nano Research Laboratory at RMIT.

“But our work also opens up the possibility of using stem cells more efficiently for treating lung disease, enabling us to nebulise stem cells straight into a specific site within the lung to repair damaged tissue. This is a real game changer for stem cell treatment in the lungs.”

Surface reflected bulk waves are known as such due to their combination of bulk sound waves and surface sound waves.

Bulk sound waves cause an entire material to vibrate as one, an effect that the researchers liken to holding a carpet at one end and shaking it.

By contrast, surface sound waves only cause the surface of a material to vibrate, with the researchers comparing the effect to waves in an ocean.

By combining the two, the researchers have created a sound wave class that is far more powerful than its component wave types.

“The combination of surface and bulk wave means they work in harmony and produce a much more powerful wave,” said Rezk.

“As a result, instead of administering or nebulising medicine at around 0.2ml per minute, we did up to 5ml per minute. That’s a huge difference.”

The researchers have created a device to utilise surface reflected bulk waves in medical devices with the rather epic name HYDRA.

This passes electricity through a piezoelectric chip, converting it into mechanical vibration, or sound waves, that can break liquid into a spray so it can be inhaled.

“It’s basically ‘yelling’ at the liquid so it vibrates, breaking it down into vapour,” explained Rezk.

HYDRA has been used to improve RMIT’s advanced nebula, known as Respite, which can be used to deliver a wide range of drugs into the body without the need for pills or injections.

For sufferers of asthma and cystic fibrosis, the device can deliver highly precise drug doses, but it can also be used to provide diabetes patients with insulin, and give infants vaccines without an injection.

The details of the research have been published today in the journal Advanced Materials.

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.
