Rosenior, 41, parted company with the Blues following a fifth straight Premier League defeat where the team had failed to score.

The former Hull and Strasbourg boss signed a six-and-a-half-year deal in January, midway through the season, but his reign at Stamford Bridge has been cut short after less than four months - including seven losses in the last eight matches.

He started brightly, winning his first four Premier League games in charge and leading the team to the last 16 of the Champions League.

But the side have dropped down the table and are at risk of missing out on Champions League qualification for next season.

A 3-0 loss at Brighton on Tuesday made it five consecutive Premier League losses without scoring, for the first time since 1912.

Rosenior leaves Chelsea seventh in the table, seven points off Liverpool in fifth, who have a game in hand.

Calum McFarlane, who led the team for two matches following the departure of Enzo Maresca in January, will take charge as interim head coach until the end of the season, starting with Sunday's FA Cup semi-final against Leeds at Wembley.

Chelsea FC said in a statement that Rosenior "has always conducted himself with the highest integrity and professionalism".

"This has not been a decision the Club has taken lightly, however recent results and performances have fallen below the necessary standards with still so much more to play for this season. Everyone at Chelsea FC wishes Liam every success in the future."

Rosenior called his side's performance "indefensible" on Tuesday after a poor result at the Amex Stadium.

During the game, he was subjected directly to chants from supporters urging him to leave.

"I understand their frustration," he said of the fans.

"The buck stops with me."

The club are not in active discussions with candidates and intend to take their time over the next appointment, with no decision expected before the end of the season.

Rosenior had been appointed as a surprise replacement for Maresca.

Rosenior had signed a six-year contract with Chelsea when he moved from Strasbourg, owned by the Blues' parent company BlueCo.

Chelsea's collapse under Rosenior started with a 5-2 thrashing away to Paris St Germain on 11 March and from there the rot set in.

The team have since dropped down the league table, having not picked up a point since a win against Aston Villa on 4 March.

The robotic arm, built by Japanese electronics giant Sony, is a paddle-wielding robot by the name of Ace.

Ace was pitted against professional athletes and was found to have given them a real challenge with its nine camera eyes positioned around the court.

The robot, which also has eight joints that direct its movements, learned how to play the sport using the AI method known as reinforcement learning.

"There's no way to program a robot by hand to play table tennis. You have to learn how to play from experience," said Sony AI researcher Peter Dürr, co-author of the study published in the science journal Nature.

Sony said it is the "first time a robot has achieved human, expert-level play in a commonly played competitive sport in the physical world - a longstanding milestone for AI and robotics research".

Michael Spranger, president of Sony AI, said: "Speed is really one of the fundamental issues in robotics today, especially in scenarios or environments that are not fixed.

"We see a lot of robots that are in factories that are very, very fast.

"But they're doing the same trajectory over and over again. With this technology, we show that it's actually possible to train robots to be very adaptive and competitive and fast in uncertain environments that constantly change."

An Olympic-size table tennis court was built at Sony's headquarters in Tokyo to conduct the experiments, so professional and other highly skilled athletes had a "level playing field" with the robot, Mr Dürr said.

Mr Spranger said it was important the robot didn't have too unfair of an advantage - its speed, arm's reach and performance were made comparable with a skilled athlete who trains at least 20 hours a week.

It plays by official table tennis rules on a typically sized court.

"It's very easy to build a superhuman table tennis robot," Mr Spranger said.

"You build a machine that sucks in the ball and shoots it out much faster than a human can return it.

"But that's not the goal here. The goal is to have some level of comparability, some level of fairness to the human, and win really at the level of AI and the level of decision-making and tactics and, to some extent, skill."

That means, he said, that "the robot cannot just win by hitting the ball faster than any human ever could, but it has to win by actually playing the game".

Saffie Sandford was the first to be given the cutting edge treatment that involved injecting a copy of the gene straight into her eye.

The schoolgirl, from Stevenage in Hertfordshire, has the rare inherited condition Leber's Congenital Amaurosis (LCA), which stops cells in the eye from making a specific protein needed for normal vision.

Babies and children with the condition have low vision in daylight and no vision in reduced light. They can lose their sight entirely in adulthood.

Doctors said that without the treatment, Saffie would be blind by the age of 30.

Spider-Man fan, Saffie, was diagnosed at Moorfields Eye Hospital in London when she was five after her parents noticed she was finding it hard to see in the dark.

She was then transferred to Great Ormond Street Hospital (Gosh) to have the gene therapy, called Luxturna.

The one-off therapy is a first-of-its-kind treatment for one of the genetic causes of LCA, containing a healthy copy of the eye gene.

Saffie's mother Lisa said: "Saffie's diagnosis came as a huge shock to us as we'd never heard of the condition or knew me and her dad Tam were carriers.

"It was such a rollercoaster of a journey, but we were so relieved and grateful when we heard there was a treatment available on the NHS for Saffie."

She described her condition as "really life-limiting" before the treatment, adding that she was blind in the dark, which made daily activities challenging.

Saffie underwent eye gene therapy in her first eye in April last year and in her second eye in September.

She already wore glasses, having been diagnosed as short-sighted at the age of two.

"Having the gene treatment has been life-changing, it's like someone waved a magic wand and restored her sight in the dark," Lisa said.

"We've been able to take her trick-or-treating and out to restaurants in the evening - something that was impossible before."

She said Saffie's peripheral sight in the daylight has also improved and she's now able to spot hazards and has improved at school.

Her mother said she is now thriving and you wouldn't be able to tell she has the condition, adding that she can take part in normal activities that a six-year-old enjoys, such as playing on a climbing frame.

Lisa said the results have been "incredible", noting they are "eternally grateful that our little girl has been given her sight back".

"We know it might not last forever, but we feel fortunate every day that she has been given this chance," she said.

It comes as recently published research by researchers at Gosh and University College London (UCL) showed that Luxturna can improve sight and strengthen visual pathways at a critical stage of brain development.

That's changing. Now, fully commercial sites are springing up all over the open web.

The Internet Watch Foundation, the organisation charged with removing child sexual abuse material (CSAM) from the internet, has seen the number of commercial sites double in the past year alone.

Some of them are hidden behind apparently innocent website fronts, others are just sitting in the open, just a few clicks away from your social media feeds.

The criminals running these sites aren't selling access to one or two videos of 'category A' material - the worst level of designation content assigned by police.

They're encouraging users to download - and pay for - terabytes of content at a time. But like any business, they need a marketing strategy. They've chosen word of mouth.

"[They're using] 'refer-a-friend' schemes whereby if you view the content and you want more, you can spread that link around your social media accounts, and then the more clicks that content gets," according to Mabel, an anonymous analyst at the IWF.

"That's new. We never used to see that at all."

Mabel is one of the few people in the world who is legally allowed to hunt down and remove CSAM from the internet. She's also a grandmother.

She added: "I worry that my grandchildren will be presented with these sites in their feeds on their social media, not realise what they are and click on them."

Nearly every refer-a-friend scheme was reported to the IWF by a member of the public, rather than a trained analyst.

That worries analysts like Mabel because it suggests ordinary people are now stumbling across this extreme abuse material in a way they never have before.

"I come into work every day and I know what I'm going to see. I'm expecting to see the content that I see on the internet," she said.

"But can you imagine if you turned on your phone, turned on the computer, and within a few clicks you saw category A content? You can't unsee that once you've seen it."

A lot of tech firms, like social media companies, have recognised the harm that seeing such extreme content can do to their employees. Social media moderators are routinely exposed to CSAM, extreme violence and death. It has an impact.

Two years ago, moderators from Meta began legal action against the company after more than 140 of them were diagnosed with severe PTSD.

Other major social media sites like TikTok are also facing legal action over their treatment of moderators and, as a result, many companies are turning to AI to deal with the majority of extreme content.

They say it will help ease the severe mental load for their human workers.

Even the Metropolitan Police announced last week that it will begin exploring how AI could help the force analyse large volumes of CSAM, leaving officers free to "focus human expertise where it is needed most".

So what about the IWF, where analysts are dealing with more content than ever before? They've seen a 6% increase in the amount of CSAM online in the last year alone.

"Artificial intelligence tools are a supplement, right?" IWF chief executive Kerry Smith said.

"They're a supplement to human intelligence. They aren't a replacement."

She believes her human analysts are worth the cost of the mandatory monthly counselling, stringent recruitment process and ongoing psychological care, because of their "offline understanding" of the internet's underbelly.

"[They have an] understanding of how abuse occurs, what exploitation looks like, how you find particular indicators within those images and within those videos that can help identify an individual," Ms Smith said.

"So I think artificial intelligence is a weapon that we could use to prevent online child sexual abuse and exploitation, but it's not a replacement for human intelligence and human insight."

Christopher Trybus, of Swindon, Wiltshire, stood trial accused of causing the death of Tarryn Baird, who died aged 34 in November 2017.

The 44-year-old defendant also faced charges at Winchester Crown Court of controlling and coercive behaviour and two charges of rape.

He has been cleared of all charges.

Speaking outside court and accompanied by his current wife, Mr Trybus said: "After three police investigations over the course of 10 years, I'm relieved that the jury has carefully considered the evidence and reached the correct verdict today.

"I want to thank my wife, my family, and my friends for their unwavering support - and my legal team for their hard work and dedication throughout the process.

"This has had a profound impact on my life and on those closest to me. It's been an incredibly difficult experience.

"I would also like to acknowledge that domestic abuse is a very real and serious issue, and victims must always be supported.

"Right now, I'll focus on moving forward and rebuilding my life with my family."

It was the first case of its kind in England and Wales.

Mr Trybus, who denied the offences, claimed his wife made the allegations as a result of mental health issues, including a probable diagnosis of post-traumatic stress disorder (PTSD) after she witnessed violent car-jackings in South Africa, where the couple grew up.

The defendant, who runs an IT business, also said he was out of the country when some of the incidents were alleged to have taken place.

The judge, Mr Justice Linden, thanked the jurors for their service and told them: "It was a difficult and sad case and the stakes were high for the families involved so we understand your task has not been an easy one and no one should underestimate your role in these proceedings."

Describing how he felt about Ms Baird in light of the allegations, Mr Trybus told the court: "It's such a complex feeling, I loved her dearly and she has gone and said all of these things.

"At no point has this ever happened, it's such a mix of emotions, I am upset that she said these things but she is not here so I can't be upset with her, it's not something I can put into words."
