3D printing to revolutionise surgery

By Enda Brady, Sky News correspondent

Transplant surgery in the UK could soon be transformed thanks to 3D printing that helps doctors practice operations in advance and spot any issues before they happen.

Each machine costs £250,000 but surgeons say the device could save them costly time in operating theatres and ultimately help speed up patient recovery.

"This is a very clever use of technology because it allows us to effectively create scale size replicas of the organ being transplanted and the abdomen that it's going into," consultant transplant surgeon Nicos Kessaris told Sky News.

"In a small number of cases there's a complexity, whether it's with the size of the organ being transplanted or with the vessels, so if there is a complexity this allows us to practise the operation in advance."

Three-year-old Dexter Clark from Reading was one of the first patients to benefit after his father Brendan donated one of his kidneys, which turned out to be larger than average.

"It's just amazing that they were able to do this," said Dexter's mother Emily. "If they hadn't been able to perform the operation Dexter would have had to go on dialysis and wait until he got bigger."

The 3D work is being pioneered in London by Guy's and St Thomas' NHS Foundation Trust and could eventually be rolled out nationwide.

"If we can take one or two hours off each procedure, that's a serious saving in terms of theatre time," said Phil Reeves from Stratasys, the firm behind the technology.

"It would also be hugely beneficial for patients in terms of their recovery, so there's a huge economic argument there for the health service and the use of 3D printing."

Branson’s astronaut training as space race hots up

Sir Richard Branson has said he is undergoing astronaut training and is just months away from being catapulted into space.

The 67-year-old Virgin boss has set his sights on turning commercial space travel into a reality since he founded Virgin Galactic and hopes to be among the first space tourists.

"We're talking about months not years – so it's close. There are exciting times ahead," he told BBC Radio 4's You And Yours, to be broadcast on Monday.

"I'm going for astronaut training, I'm going for fitness training, centrifuge and other training so that my body will hopefully cope well when I go to space."

He said he has increased his fitness training by playing tennis four times a day.

"Instead of doing one set of tennis every morning and every evening I'm doing two sets. I'm going kiting and biking – doing whatever it takes to make me as fit as possible."

Sir Richard is also taking part in gruelling centrifuge training which recreates the pressures the human body experiences during space flight.

All astronauts endure G-force training which simulates the experience of take-off and travel through the earth's atmosphere.

Earlier this year Virgin Galactic completed a supersonic test flight of its SpaceShipTwo passenger rocket ship.

It was the first return to the air for the company since a crash in the Californian desert in 2014 in which one pilot was killed and another was injured.

Sir Richard, tech entrepreneur Elon Musk and Amazon founder Jeff Bezos are in a race to get tourists into space.

While Sir Richard believes Mr Musk is "doing fantastically well" in getting cargo into space and building bigger and bigger rockets, the real tussle is between the Virgin boss and Mr Bezos.

"I think we're both (Sir Richard and Mr Bezos) neck and neck as to who will put people into space first," he said.

"Ultimately we have to do it safely. It's more a race with ourselves to make sure we have the craft that are safe to put people up there."

‘Unlikely’ string of events sees Alexa go rogue

An American woman says she feels "invaded" after an Amazon Alexa device recorded a private conversation and sent it to a random contact without being asked to.

US news outlet KIRO 7 reported that a woman, identified only as Danielle from Portland, Oregon, had been unaware of what happened until she received a phone call from her husband's employee.

The employee said that Alexa, Amazon's popular voice assistant, had recorded the family's conversation and sent it to him.

Luckily, the conversation was not too personal – it was about hardwood floors.

Nonetheless, Danielle said she felt "invaded".

She added: "Immediately I said: 'I'm never plugging that device in again, because I can't trust it'."

Amazon confirmed the woman's conversation had been inadvertently recorded and sent, blaming an "unlikely" string of events for the error.

Alexa starts recording after hearing its name or another "wake word" chosen by users, meaning that even having a TV switched on can result in the device being activated.

Amazon said this was what happened to Danielle, adding: "The subsequent conversation was heard as a 'send message' request.

"At which point, Alexa said out loud 'To whom?' At which point, the background conversation was interpreted as a name in the customer's contact list.

"We are evaluating options to make this case even less likely."

Amazon wants Alexa to become a popular home accessory, used for everything from dimming the lights to ordering a pizza, but to achieve this, it must be able to assure users of the device's security.

There were fears raised after US researchers found in 2016 that sounds unintelligible to humans could set off voice assistants.

According to The New York Times, the group showed that they could hide commands in white noise played over loudspeakers and through YouTube videos to get smart devices to turn on flight mode or open a website.

In May, some of those researchers went further, saying they could embed commands directly into recordings of music or spoken text.

This would mean that, while a human listener hears an orchestra, the voice assistant might hear an instruction to add something to your shopping list.

Govt facial recognition delays ‘unacceptable’

By Alexander J Martin, technology reporter

The government's approach to a High Court ruling regarding facial recognition technology has been slammed as "unacceptable" by MPs.

As revealed by Sky News last year, police in the UK have amassed the facial images of more than 20 million people, including hundreds of thousands of innocent citizens.

These images have been used to automatically scan crowds across the country despite questions over whether this constitutes illegal mass surveillance.

The activity has also been challenged by a High Court ruling in 2012 which said that retaining the pictures of innocent people on the custody images database was unlawful.

Despite this ruling, the government said it would be too expensive to delete innocent people's images and told police forces only to consider whether to delete images if the innocent individuals themselves complained.

This was slammed as "unacceptable" by the MPs, who explained that "unconvicted individuals may not know that they can apply for their images to be deleted".

The committee noted a report by Associated Press that only 67 of hundreds of thousands of innocent individuals had applied to police forces to have their images deleted.

In a report published on Friday, MPs on the science and technology committee criticised the government for being four years late in producing the biometrics strategy it had promised would address these issues.

The biometrics strategy is now technically five years overdue as it was originally to be published as a joint biometrics and forensics strategy in 2013.

Although the government said it would be publishing separate strategies in 2014, the publication date for the biometrics strategy has still not been confirmed.

MPs have demanded that it must be published by June of this year.

A Home Office spokesperson said: "Analysis of images plays a critical role in helping the police to protect the public. When doing so it is important that the police act legally, ethically, and transparently.

"We are examining whether, with new police IT systems, it will be technically feasible to link custody images to conviction status as is the case with fingerprints and DNA."

The Home Office say they are now considering the Select Committee's report and are "committed to publishing the Biometrics Strategy in June".

The forensics strategy was two years late when it was published in 2016, although it was still criticised as "inadequate" and "vague and incoherent".

A series of scandals have since rocked police handling of forensic evidence, prompting the MPs to demand a rewrite of the strategy.

The report published on Friday states that police are "unduly focusing on cutting costs" which is causing damage to producing evidence.

Their criticism comes as an urgent review is being conducted into the Metropolitan Police amid allegations that 33 cases were affected by forensics mishandling.

Last November, Sky News reported that rogue laboratory staff at the outsourced forensics firm Randox Testing Services may have tampered with evidence in more than 10,000 cases, including murders and sex crimes.

A Home Office spokesperson said: ""The majority of forensic services are being delivered to a higher-quality standard than ever before and are closely scrutinised.
