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.

Researchers develop painkiller with no side effects

Tests of a new painkiller, Tiovyurtsin, have shown that it works for longer, suppresses pain symptoms of various etiologies and has no toxic effects on the body. Prolonged use (28 days) of the drug does not induce drug dependence, so the drug could be used as a replacement for morphine.

New species of giant herbivorous dinosaur found in outback Australia

A new species of giant herbivorous dinosaur, called Savannasaurus elliottorum, has been found in outback Australia. The new specimen has led researchers to propose a new theory of how the species spread across the ancient megacontinent of Gondwana, which joined Australia, Africa, Antarctica and South America.

Our theory on how solar systems are formed might be wrong

The discovery of the first "binary–binary" – two massive companions around one star in a close binary system, one so-called giant planet and one brown dwarf, or "failed star" – has led a University of Florida astronomer to question whether what we understand about solar system formation is correct.

Nintendo's new console is a hit with fans but not with investors

Shares in Nintendo fell by as much as 7% following the release of a teaser video for its upcoming hybrid games console the Nintendo Switch. Despite a largely positive reception from fans and media alike, Switch failed to wow Japanese investors, with many, it seems, not ready to forgive Nintendo for the performance of the Wii U.

Tesla to make all its new cars self-driving

Electric carmaker Tesla has said all of its cars will have the hardware – basically a super-computer in a car – needed to drive completely on their own. But despite cameras, sensors and radars being introduced, it is still expected to be years before Tesla's vehicles become fully self-driving.

Factor Magazine Issue 29: The Future of Politics – Out Now

In a Venn diagram of politics and unbelievable events, 2016 represents the meeting point, where we finally acquiesced to madness and accepted that it is perfectly reasonable for Donald Trump to run for president.

But beyond Trump’s potential presidency there are loads of examples that prove 2016 is the maddest year in Western politics in living memory. Britain has voted to leave the European Union; the US Democratic nominee was investigated by the FBI and – I don’t know if we mentioned – the US Republican nominee is Donald Trump. Add the alleged Russian hack of the Democratic National Committee (DNC) and Recep Tayyip Erdoğan’s increasingly bizarre behaviour following the totally-not-fake Turkish coup, and you have a year where nothing, no matter how improbable, is definitely off the political table.

So in this, our politics issue, we attempt to make sense of the madness and find out how technology is turning the tables on “post-truth politics”.


With the presidential election just weeks away, we look at how technology has played a role on the campaign trail, and ask whether a growth in support for third-party candidates could ever one day lead to them being a viable alternative to president.

Plus with accusations of Russia ordering a state-sponsored cyber attack on the DNC, we hear from Shawn Henry, former executive assistant director of the FBI, to consider the impact hacking is having on democracy.

On the other side of the Atlantic, the European Union is in peril. We discover how Brexit is just the start, and find out what lies ahead for the stricken community. Plus we look at Turkey’s bizarre move to ban cloud-based file sharing services, and ponder the motives behind such a decision.


On both sides of the pond, truth has become highly mutable within politics this year. We look at whether automated fact checking could allow technology to bring truth back to politics, consider the statistics behind Trump and Clinton’s statements and find out how The Simpsons predicted Trump’s rise 16 years ago.

Plus, we look at how deep learning could be used to more accurately predict election results, and consider the technology being used to better engage voters. And if that wasn’t enough, we’ll also look at the UK financial system’s tentative embrace of cryptocurrencies.

And if you’re sick of politics, we also hear from ESA astronaut Tim Peake about his six-month stay on the International Space Station, and discover how a simple change of camera angle laid the foundations for the Total War games we know and love.

As well as this there’s all the latest news, reviews, and we’ll look at Marty McFly’s Nike Mags and see how the sewing industry is about to be automated in Issue 29 of Factor magazine – out now on iPad and online.

Scientists unlock wireless charging for airborne drones

Using inductive coupling, scientists have made a breakthrough that allows them to wirelessly transfer power to a drone while it is still flying. The technology could open up a host of possibilities, including allowing drones to fly indefinitely, simply hovering over a ground support vehicle when in need of a recharge.

Inductive coupling is a concept originally demonstrated over 100 years ago by Nikola Tesla, the principle being that by tuning two copper coils into each other with electronics, you can enable the wireless exchange of power at a certain frequency.

Inductive coupling has been experimented with for decades, but until now researchers have failed to utilise the technology to wirelessly power flying devices.

The researchers behind the breakthrough, from Imperial College London, demonstrated their method by altering the electronics and removing the battery of an off-the-shelf quadcopter drone.

A receiving antenna was made by encircling the drone’s casing with a copper foil ring, and a transmitter device on the ground was made out of a circuit board and connected to electronics and a power source, creating a magnetic field. The researchers believe that this is the first demonstration to show how this wireless charging method can be efficiently used with a flying object, and expect it to open up a range of potential applications.

“Imagine using a drone to wirelessly transmit power to sensors on things such as bridges to monitor their structural integrity,” explained Professor Paul Mitcheson, from the Department of Electrical and Electronic Engineering at Imperial College London. “This would cut out humans having to reach these difficult-to-access places to re-charge them.

“Another application could include implantable miniature diagnostic medical devices, wirelessly powered from a source external to the body. This could enable new types of medical implants to be safely recharged, and reduce the battery size to make these implants less invasive.”

Drones are currently limited in their commercial usage by the distance they can travel and the duration for which they can do so.

Despite growing possibilities for usage, the limited availability of power and re-charging requirements means that it is hard to make full use of drones in their capacity for roles such as surveillance or search and rescue. The development of efficient wireless power transfer technology would solve these endurance problems and enable a wide range of advancements.

“In the future, we may also be able to use drones to re-charge science equipment on Mars, increasing the lifetime of these billion dollar missions,” added Mitcheson.

“We have already made valuable progress with this technology and now we are looking to take it to the next level.”

For now, the technology is still very much in its infancy and the Imperial team’s technology only allows the drone to fly ten centimetres above the magnetic field transmission source.

However, they are now exploring collaborations with industrial partners, and have estimated that a commercially available product could be ready in a year.
