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 man, Gert-Jan, who suffered a spinal cord injury in a bike accident 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,” Gert-Jan 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 Gert-Jan 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.

Read Thomas Moore’s full analysis here.

Gert-Jan 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.

‘We’ll be back tomorrow’: The migrants risking it all – and the ‘rubber bullets’ – to get to the UK

'We'll be back tomorrow': The migrants risking it all - and the 'rubber bullets' - to get to the UK

If you want to understand why people are still risking everything to cross the Channel, let me take you to a quiet street near Dunkirk, where chaos is in the air.

A group of around 40 or 50 people – migrants who have just failed in their latest attempt to cross the Channel – are being corralled down the road. They are tired and bruised. The police are around them, like teachers trying to take control of an unruly school trip.

Behind, police officers on foot, shouting instructions in French that almost nobody can understand. The group turns, as one, and heads down a side road that leads to a field.

“Non, non,” shouts the policeman, exasperated. His head rolls back. “NON,” he bellows, then runs after them.

These people are mostly strangers to each other, united by the single aim of reaching Britain. We had seen the group 12 hours earlier, crossing another field, clearly on their way to a nearby beach, but then they disappeared from our sight, heading off down an alleyway between houses.

Like so many people, they had attempted to make the crossing, and failed. This time, according to one of those we spoke to, the cause was the police, patrolling these beaches throughout the night.

As the group tried to take a boat to the shore, the police punctured it, rendering the vessel useless.

But that’s not all. They also claimed the police had used rubber bullets to disperse them.

Bich, a Vietnamese woman who we find sitting on the ground, tearfully exhausted, rolls up her trouser to expose a nasty, vivid bruise.

“We went towards the boat but the police shot at us. They destroyed the boat and it sank. And then they shot me.”

“Plastic pistols,” is how another man described the weapons, showing me a much bigger bruise on his thigh. A third has a circular bruise, with a dot in the middle, as if he has been hit by the top of a canister.

Some of the migrants claimed they were shot with 'plastic pistols'.

The group was a varied bunch. Very often, over the years of talking to migrant groups of northern France, they have been united by background – one boat is full of Iraqi Kurds, say, while another is packed with Afghans.

But here, we found an international group.

Yes, Kurds, Iraqis and Afghans, but also Syrians, Vietnamese, Sudanese and, hidden behind a cap and jumper pulled over his mouth and nose, a man who told me he was from Morocco.

Some have been determined to reach Britain ever since they left their home countries. Others are more pragmatic. One more told me he had wanted to stay in France but had just been told he was going to be deported.

“We have problems but we are being deported, so we want to go to Britain for a better life,” says one. “Deport, deport,” shouts another man.

So Britain may represent his last chance at asylum as a host of European nations start to increase the number of deportation orders they issue.

The European Union has just concluded a long-debated agreement on migration, intended to toughen both its borders and its resolve.

Sweden, France, Italy and plenty of others are using much tougher rhetoric about removing people from their territory who have been refused asylum. And the results are beginning to be seen.

Germany, which opened its doors to more than a million people fleeing Syria, is among those increasing its number of deportations, with 20% more migrants sent away in the first two months of this year compared with the same period of 2023.

And then, of course, there is the UK’s Rwanda plan, designed to deter people from making these crossings, backed by the prime minister’s unequivocal promise to bring down the number of small boats crossing the Channel.

If they knew about the Rwanda plan, and certainly some did, then they shrugged it off as either ineffective, unjust or simply untrue.

“The UK cannot send me to Africa after what you have done to my country and my area,” said one Syrian man. He knew about the Rwanda policy and said it was “not true”.

“It is not safe in Rwanda so you cannot send people there,” insisted another person, perhaps unwittingly getting to the nub of so many parliamentary exchanges.

“There are people who are trying to escape from Rwanda because of what is happening there. So you cannot say it is safe.”

There is a great deal stacked up against these groups of migrants. The British government doesn’t want them to come, they claim the police in the Dunkirk area have attacked them, the crossing is dangerous and expensive and there is a growing tide of antipathy towards migrants across much of Europe.

Yet none of these people seem deterred, promising to persevere, resolutely sure that reaching British shores will be a panacea to their woes.

“We will be back tomorrow,” says a young man with a wispy beard and a wide smile. “We want to get to the UK.”

His friend next to him simply grinned at me. “UK is good,” he said, with a thumbs-up.

The group amble off, back towards their camp near Grande-Synthe, a town that has become a magnet for migrants. They are exhausted and, in some cases, battered. But they will try again. Soon.

Major General Aharon Haliva: Israeli intelligence chief quits IDF over 7 October attack

The Israeli military intelligence chief has resigned after failures that led to the deadly 7 October Hamas attack on Israel.

Major General Aharon Haliva was one of several senior commanders who said they failed to predict and prevent the most devastating attack in the country’s history.

He is the first senior figure to quit the IDF since the assault.

In his resignation letter, he said the intelligence division under his command “did not live up to the task we were entrusted with”.

Major General Haliva, who has served 38 years in the IDF, added: “I carry that black day with me ever since, day after day, night after night. I will carry the horrible pain of the war with me forever.”

Lower-level intelligence officials reportedly had information that Hamas was hatching a plan to launch an attack, but Israel did not foresee the group’s surprise attack when militants stormed the Gaza border and rampaged through Israeli communities, military bases and a music festival.

Some 1,200 Israelis and foreigners were killed, mostly civilians, while about 250 were taken as hostages in Gaza.

Hours after the assault, Israel declared war on Hamas – which is now into its seventh month – with the aim of eradicating the militant group and rescuing the hostages.

More than 34,000 Palestinians have been killed since, mostly women and children, according to the Hamas-run health ministry.

Other IDF chiefs were expected to resign after 7 October as some acknowledged the failures involved, including Lieutenant-General Herzi Halevi, and the head of the domestic intelligence agency Shin Bet Ronen Bar, but both have remained as the war continues.

On the failures, Israeli Prime Minister Benjamin Netanyahu previously said “everyone will have to give answers” including himself, but he has so far not accepted direct responsibility.

The IDF said its chief of general staff had thanked Major General Haliva for his service where he made “significant contributions to the security of the State of Israel as both a combat soldier and commander”.

Israeli opposition leader Yair Lapid welcomed the resignation on X, saying it was “justified and dignified” adding: “It would be appropriate for Prime Minister Netanyahu to do the same.”

‘We will make our own decisions’

Netanyahu ‘will fight’ IDF sanctions

Meanwhile, the US is set to impose sanctions against the IDF battalion Netzah Yehuda for alleged human rights violations while operating in the occupied West Bank, the US-based Axios news site reported on Saturday.

The IDF said it was not aware of such measures as Mr Netanyahu added: “If anyone thinks they can impose sanctions on a unit of the IDF – I will fight it with all my strength.”

Washington had called for a criminal investigation after the battalion’s soldiers were accused of being involved in the death of Palestinian American, Omar Assad, who died of a heart attack in 2002 after he was detained and later found abandoned at a building site.

A battalion commander was reprimanded and two officers were dismissed, but Israel did not seek criminal charges.

There have been other incidents more recently, some captured on video, where Netzah Yehuda troops were accused of, or charged with, abusing Palestinian detainees.

US President Joe Biden said an announcement could be made “very soon”.

China floods: Four dead as cities submerged after days of record breaking rainfall

Footage from China shows rescuers racing to evacuate trapped residents and streets inundated with water after the country was hit by intense floods and record-breaking rainfall.

Southern cities in China have been battered as heavy rainfall has flooded cities on the Pearl River Delta – once dubbed the “factory floor of the world”.

The downpours have killed four people in Guangdong province as of Monday, according to state-owned Xinhua News Agency. Ten others are still missing.

The severe weather also threatens to overflow major rivers, waterways and reservoirs, leading China’s water resource ministry to issue an emergency advisory, according to state media.

Since Thursday, 36 homes have been destroyed in the province, home to more than 127 million people, while 48 were left severely damaged.

The north of Guangdong’s capital Guangzhou, as well as the cities of Shaoguan, Zhaoqing and Jiangmen have been left half-submerged in floodwater.

Pictures also show residents of Qingyuan, a city of four million, using boats to cross flooded roads.

As of Sunday afternoon, a total of 82,559 people had been evacuated across the province.

Meteorologists have blamed the extreme downpours on global warming, noting that weather events have become more unpredictable.

Qingyuan resident Lin Xiuzheng, an online retail sales worker, told Reuters that before 2022 the flood-waters were never as high as they have been in recent years.

Guandong province was also hit with severe flooding two years ago.
