How Lyhanna’s murder case is shedding light on child abuse in France | Child Rights News

How Lyhanna’s murder case is shedding light on child abuse in France | Child Rights News

Published by Sam Flores

This article contains details some readers may find distressing. The case of Lyhanna, an 11-year-old girl raped and killed in the southwestern town of Fleurance, has shaken France for more than a month, leading to protests calling for the protection of children and forcing the government to promise sweeping reforms on the issue. Lyhanna went missing on May 29 after getting into a car with a man prosecutors claim was Jerome Barella, the 41-year-old father of one of her schoolmates. Her body was found six days later in an abandoned grain silo. Barella has been charged with abduction and unlawfully confining a minor and remains in pre-trial detention, though the cause of death has not been officially confirmed. He denies the charges. What turned grief into national outrage was the revelation that Barella had already faced two prior accusations of raping minors – both dropped or stalled. A third complaint, filed in August 2025 by the mother of a 10-year-old girl, accused him of repeatedly raping her daughter at his home. That case bounced between …

CurrentBody Multi Light Therapy LED mask review: hands down the best I’ve tested | Skincare

CurrentBody Multi Light Therapy LED mask review: hands down the best I’ve tested | Skincare

Published by Sam Flores

I’ve been testing LED masks for a couple of years now, and the CurrentBody Series 2 red-light face mask has long been my favourite option for anti-ageing. It’s comfortable, offers excellent coverage and powerful deep near-infrared treatments. Sadly, it doesn’t work for other skin concerns. It’s a one-trick pony. The Guardian’s journalism is independent. We will earn a commission if you buy something through an affiliate link. Learn more. So, when I heard that CurrentBody had launched its Multi Light Therapy mask with five different modes, I was interested to see how it would stand up to the stellar performance of its predecessor. As someone with hormonal acne, I was especially keen to try the mask’s “clearing” mode, but it also offers a calming “restoring” mode, a pigmentation-reducing “brightening” mode, and a distinctive “complete” mode, as well as the “anti-ageing” mode. That’s enough versatility to satisfy even the most temperamental skin, but it comes at a price. At a penny shy of £500, you could afford a short European getaway or luxury spa trip instead. So …

Resuscitated human retinas respond to light 10 hours after death

Resuscitated human retinas respond to light 10 hours after death

Published by skeptic

Keeping the retina working while out of the body is a step towards effective transplants Michael Lutz/Alamy Human eyes have been kept active outside the body for up to 10 hours after death, double the length of time that had previously been achieved. Supplying donor eyes with blood and oxygen meant they continued to respond to light, while also preserving their structure and overall health for 24 hours. “This work undoubtedly represents an important step towards the possibility of whole-eye transplantation,” says Thomas Johnson at Johns Hopkins University in Baltimore, Maryland, who wasn’t involved in the research. “Maintaining light responses outside of the body is a tremendous feat.” More than a million people in the UK are blind or partially sighted because of an irreversible eye condition, such as age-related macular degeneration, which affects the retina, the light-sensing tissue at the back of the eye. Some advances have been made. For instance, corneal transplants, which replace the clear “window” in front of the eye with donor tissue, can improve vision in people with damaged corneas. …

Empire State Building Light Blue for Taylor Swift-Travis Kelce Wedding

Empire State Building Light Blue for Taylor Swift-Travis Kelce Wedding

Published by Daniella Wilson

Taylor Swift’s something blue theme for her glitzy wedding to Travis Kelce on Friday became an Empire State Building lit blue over the New York City skyline. The glow up came as the power couple tied the knot as part a multi-day Madison Square Garden wedding celebration, reportedly stretching from Thursday night into Saturday morning. Leading up to the event, Manhattan’s popular skyscraper on its website said the light blue sparkle glow up was “in celebration of Taylor Swift and Travis Kelce’s wedding at Madison Square Garden.” That continues a tradition of the Empire State Building and its Art Deco façade lighting its spire to mark major occasions in the city. That includes the spire and its LED lighting system set to glow red, white and blue on Saturday to mark the 4th of July celebrations. And for Swift, the blue color is a shout out to the Old English rhyme, “Something Olde, Something New, Something Borrowed, Something Blue, A Sixpence in your Shoe,” meant to offer protection to a bride on their wedding day. A giant lighting …

Beaten Briton Choinski rages at ‘impossible’ Wimbledon light

Hello and welcome to coverage from Wimbledon as Great Britain’s Jacob Fearnley takes on Jaume Munar. Fearnley needed a wild card to get into the tournament after a difficult 12 months so fighting back from two-sets down to beat American Alex Michelsen was a real shot in the arm for the Scotsman. “I have practised with him a lot,” said the 24-year-old. “It is not an easy match, but there are worse draws out there. Two years ago, I drew Novak [Djokovic]. “You do kind of go into the match thinking you’re in it, where sometimes when I have drawn [Alexander] Zverev second round, you kind of just go in thinking, ‘Well, I’ll try and get some games’.” Munar, the world No 44, beat Queen’s Club champion Francisco Cerundolo in the second round. Fearnley could receive a visit from the Princess of Wales, who is at the All England Club today. Dressed ‌in ‌a ⁠blue outfit, the 44-year-old made her way to Court 18 to watch Arthur Fery and was seated ​beside British former ‌semi-finalist …

New ultra-black, carbon and nanotube car paint absorbs 99.90% of visible light

New ultra-black, carbon and nanotube car paint absorbs 99.90% of visible light

Published by Jenni Sidey

A car painted in deep black already carries a certain message, sleek, expensive, a little intimidating. Now researchers say they have found a more practical way to push that look even further, creating an ultra-black automotive coating that absorbs almost all visible light while still holding up under tests that matter to carmakers. The new coating combines carbon black pigment with carbon nanotubes, producing a finish that absorbed an average of 99.90% of visible light in the team’s measurements. Just as important, the material was designed to work in a form that can actually be processed into automotive paint, rather than remaining a striking but impractical lab demonstration. “In China, car color has become a key selling point,” said Zhiwei Liu, a research chemist with Color Technology, Group Core R&D Shanghai, Nipsea Group. “Deep black finishes have long been the premium choice and signature color for luxury cars due to their elegant appearance, powerful visual impact, and luxurious undertone.” That appetite for darker and more dramatic finishes has grown in the years since a 2019 …

Strange beads of light on Ganymede look strikingly like Earth’s auroras

Strange beads of light on Ganymede look strikingly like Earth’s auroras

Published by Jenni Sidey

Ganymede’s auroras have always stood apart for one simple reason: this is a moon, not a planet, and yet it carries its own magnetic field. Now, close-range observations from NASA’s Juno spacecraft have revealed something even more surprising. The team saw bright auroral patches that closely resemble the bead-like structures seen in Earth’s polar skies. That similarity matters because those beads on Earth are tied to violent magnetic disruptions that release large amounts of energy. On Ganymede, the finding suggests the same basic physics may be at work far from home. This would occur in a vastly different environment shaped not by the solar wind alone but by Jupiter’s immense magnetosphere.
