A paralysed man has been able to walk again after communication was re-established between his brain and spinal cord using a wireless “digital bridge”.

The so-called brain computer interface is made up of two electronic implants, one each in the brain and spinal cord.

The former is placed above the region of the brain responsible for controlling leg movements, and can decode the electrical signals generated when we think about walking.

Similarly, the other implant is positioned over the part of the spinal cord that controls the legs.

Working together, scientists say the groundbreaking technology “transforms thought into action” – repairing the broken connection between the brain and the region of the spinal cord that controls movement.

The first patient was a 40-year-old Dutchman, engineer Gert-Jan Oskam, who suffered a spinal cord injury in a bike accident while working in China in 2011.

It had left him paralysed, but he noticed improvements within days of surgeons calibrating the implants.

Rediscovering simple pleasures

“The most surprising thing I think happened after two days,” Mr Oskam said.

“Within five to minutes, I could control my hips.”

Since then, after “a long journey” of training, the patient has been able to walk, climb stairs and navigate ramps.

He has also rediscovered the “simple pleasure” of standing with friends at a bar.

The implants remained effective after a year, including when Mr Oskam was unsupervised at home.

He was treated by neuroscientists and neurosurgeons from Switzerland’s Lausanne University Hospital and the University of Lausanne, and the Swiss Federal Institute of Technology Lausanne.

The implants themselves were developed by the French Atomic Energy Commission.

How does the technology work?

Guillaume Charvet, head of the project at the commission, said the implants use “adaptive artificial intelligence” to decode movement intentions from the brain in real time.

Once AI identifies the relevant signals, they are converted into sequences of electrical stimulation for the spinal cord, which activate the leg muscles and prompt the desired movement.

Remarkably, the patient experienced improvements in his sensory perceptions and motor skills that were maintained even when the digital bridge was switched off – allowing him to walk with crutches.

Professor Gregoire Courtine said this suggests the digital bridge not only repaired the man’s spinal cord, but also “promotes the growth of new nerve connections”.

AI THE KEY TO ASTONISHING BREAKTHROUGH

It’s artificial intelligence that is key here.

More than a decade ago, I spent some time in a lab with US researchers that were trying to decode brain signals from a monkey feeding itself with a robotic arm that it controlled with the power of thought.

Hundreds of signals jumped across a computer screen – and it was clear that the challenge would be detecting patterns in the data to gauge the intent.

The Swiss researchers have cracked that by carefully training the computer to pick out the signals that matter while Gert-Jan thinks about a very specific muscle movement.

The technology has clearly been transformational for one man. But now it needs to be rolled out to many more people paralysed by accidents and, the researchers hope, strokes.

It won’t be cheap, so access will be an issue. Will it just be the rich, or those with insurance payouts, who benefit?

But that’s for the future. Take nothing away from the breakthrough itself. It is astonishing. And the implications for people living with paralysis are huge.

Mr Oskam is the only patient who the digital bridge has been tested on, but it is hoped the technology could be used to restore arm and hand functions in future.

It could also be applied following other causes of paralysis, such as a stroke.

The findings have been detailed in the journal Nature.

Why Ukraine’s European allies will be nervously watching VE Day events in Red Square

Why Ukraine's European allies will be nervously watching VE Day events in Red Square

Donald Trump has a soft spot for military spectacles and autocrats.

He will be looking on with envy as Vladimir Putin parades both in Moscow today, with Chinese leader Xi Jinping flying in to join Victory Day events in Red Square.

European allies of Ukraine will be watching nervously, wary of anything that could upturn the delicate quest for peace.

President Trump‘s patience with peddling his much vaunted “peace deal” has been wearing thin and allies had feared Ukraine could be punished for it.

That would have been grotesquely unfair, of course. Ukraine has bent over backwards to accommodate Mr Trump’s one-sided diplomacy that has so far seemed to favour the aggressor in this obscene war.

True, the Trump proposal does not agree to Russian annexation of all the land already taken by force and stops short of ordering the complete demilitarisation of Ukraine, but otherwise the proposals are pretty much everything that Moscow has asked for.

The deal is being pushed by Steve Witkoff, Mr Trump’s golf partner turned chief negotiator, a man regarded by diplomats as out of his depth and lost in the rough when it comes to the arts of statecraft.

More on Donald Trump

Like his president, Mr Witkoff has a history of doing business with Russian oligarchs, an apparently starry-eyed view of the Russian leader and has called Ukraine a “false country”.

Moment of truth approaching

Mr Witkoff and Mr Trump have so far given Mr Putin the benefit of the doubt, but a moment of truth is approaching. While Ukraine has agreed to a longer ceasefire in principle, Mr Putin will not.

Ukraine’s European allies feared that Mr Trump was about to despair of progress, blame Ukraine and take US military support with him.

Then came the minerals agreement between the US and Ukraine. The breakthrough gave the US president something to show for his efforts and assuaged his desire for some kind of deal. He seems to have moved on for now, at least, and approved the first $50m of arms sales to Ukraine.

But these remain a tense few days ahead with plenty at stake.

Mr Putin’s self-declared three-day ceasefire raises the spectre paradoxically of escalation if either side breaks it.

The Russian lull is seen here in Kyiv as little more than a ploy.

If the Russian leader was serious about giving peace a chance, they say, he would have signed up to the permanent ceasefire being proposed by the Trump team.

Besides, Russia broke the last truce in Easter as soon as it had begun and used it to carry out surveillance and reinforcement operations says Kyiv. Why risk another pointless pause that is exploited by the invaders?

Escalation possible

If Russia plays the same games this time and Ukraine retaliates, there could be a significant escalation. Likewise, with any Ukrainian drone attack on Moscow during Victory Day.

Any major flare-up will not be looked on favourably by the US president if it upstages his first trip abroad this presidency, a three-day tour of the Middle East.

For now, his attention is not so much on the Ukraine conflict and he is no longer issuing threats to walk away and stop supporting the Ukrainians.

That will be a relief here in the Ukrainian capital. They would be unwise to do anything to reengage him, for now at least.

Their European allies, though, know American involvement in this war appears to be receding.

Can they fill the vacuum?

This week, they remember the sacrifices made to bring peace and security to their continent 80 years ago.

Can they find the political will and unity to do so again, even without America?

Astonishingly, given all we have been through, that is still an open question.

India will respond ‘in exactly the same light’ if Pakistan retaliates, high commissioner tells Sky News

India will respond 'in exactly the same light' if Pakistan retaliates, high commissioner tells Sky News

India will respond to any escalation from Pakistan “proportionally and in exactly the same light”, the country’s high commissioner has told Sky News.

Weeks after 26 tourists were shot dead by gunmen in Indian-controlled Kashmir last month, India carried out missile strikes in Pakistan and Islamabad-administered parts of the disputed region.

On Wednesday, India said it hit nine “terrorist infrastructure” sites, while Pakistan said it was not involved in the April attack and the sites were not militant bases.

Pakistan’s Prime Minister Shehbaz Sharif has since vowed that India will “now have to pay the price” for their “blatant mistake,” and skirmishes have also been reported along the Line of Actual Control (LAC).

Speaking to Sky’s The World with Yalda Hakim on Thursday, India’s high commissioner to the UK, Vikram Doraiswami, said “the original escalation is Pakistan’s sponsored terror groups’ attack on civilians”.

India strikes ‘reasonable,’ says high commissioner

He then insisted India’s strikes in Pakistan and Kashmir were “precise, targeted, reasonable and moderate,” adding: “It was focused principally and solely on terrorist infrastructure.

“We made it abundantly clear that the object of this exercise was clearly to avoid military escalation.

“A fact that was actually acknowledged – in a left-handed way of course – by the Pakistani side in terms of their own statements, which said the airspace hadn’t been violated.”

India awaits Pakistan’s response

Pakistan chose ‘to escalate the matter’

The high commissioner also said about claims Pakistan shot down Indian aircraft with Chinese-made fighter jets: “If it satisfies Pakistan’s ego to say that they’ve done something, they could have used that as an off-ramp to move on.

“Clearly they’ve chosen not to, and they’ve chosen to escalate the matter.”

And when asked about Pakistan’s threats of retaliation, Mr Doraiswami said: “We’re not looking for an escalation, but if Pakistan responds, as we have done, we will respond proportionally and in exactly the same light.”

He then referenced the border skirmishes, saying: “I do want to remind everybody: For the last 15 days, they’ve also opened artillery fire along the Line of Actual Control… That’s led to civilian casualties.”

The demands and challenges facing the new pope

There is a long list of demands in the new pope’s in-tray, ranging from the position of women in the church to the ongoing fight against sexual abuse and restoring papal finances.

People both inside the Catholic Church and around the world will be watching how the new pontiff deals with them.

US Cardinal Robert Francis Prevost was elected as the new pope on Thursday after just two days of conclave.

The 69-year-old, who becomes the first American pope, will take the name Leo XIV.

‘Evil will not prevail, we are all in the hands of God’, the new American Pope told the crowd.

On Friday, Pope Leo will lead his first holy mass as pontiff after already paying a surprise visit to see staff at his former residence.

Here, Sky News Europe correspondent Siobhan Robbins takes an in-depth look at the challenges facing the new pontiff.

Sexual abuse

Many Catholic insiders credit Pope Francis with going further than any of his predecessors to address sexual abuse.

He gathered bishops together for a conference on the issue in 2019 and that led to a change that allows cooperating with civil courts if needed during abuse cases.

But it didn’t go as far as forcing the disclosure of all information gathered in relation to child abuse.

Any abuse allegations must now be referred to church leaders, but reformers stopped short of decreeing that such cases should also be automatically referred to the police.

Clerical abuse victim says church still has ‘so much to do’

While many abuse victims agree they saw progress under Pope Francis, who spent a lot of time listening to their accounts, they say reforms didn’t go far enough.

The next pope will be under pressure to take strong action on the issue.

Women

Pope Francis also did more to promote women in the Vatican than any other pontiff.

Two years ago, he allowed women to vote in a significant meeting of bishops.

While he was clear he wanted women to have more opportunities, he resisted the idea that they needed to be part of the church hierarchy and didn’t change the rules on women being ordained.

His successor will need to decide if they push this agenda forward or rein it back in.

It’s a pressing concern as women do a huge amount of the work in schools and hospitals, but many are frustrated about being treated as second-class citizens. 10,000 nuns a year have left in the decade from 2012 to 2022, according to Vatican figures.

Inclusion

“Who am I to judge?” Pope Francis famously said when asked about a gay monsignor in 2013.

His supporters say he sought to make the church more open, including allowing blessings for same sex couples but while critics argue he didn’t go far enough, some conservatives were outraged.

African bishops collectively rejected blessings for same sex couples, saying “it would cause confusion and would be in direct contradiction to the cultural ethos of African communities”.

How welcome LGBTQ+ people feel in the church will depend partly on decisions made by the pontiff.

Conversely, the Pope must also bring together disparate groups within the Catholic faith.

Many are demanding a leader who can unite the various factions and bring stability in an increasingly unstable world.

The global south

While the Catholic church is losing members in its traditional base of Europe, it’s growing rapidly in the global south.

The area has become the new centre of gravity for Catholicism with huge followings in countries like Brazil, Mexico and the Philippines.

Pope Francis tried to expand representation by appointing more cardinals from different areas of the world, and the new Pope will be expected to continue this.

Finance

The Vatican is facing a serious financial crisis.

The budget deficit has tripled since Pope Francis’s election and the pension fund has a shortfall of up to €2bn (£1.7bn).

These money worries, which were compounded by COVID-19 and long-standing bureaucratic challenges, represent a major concern for the next pope.
