Google Home’s latest update will make it easier to decide who in your household can control your smart home. It comes with a new feature, which Google first started testing last year, that will let you assign people “Admin” and “Member” roles.
People with Admin status have full control of all the devices, services, and users within their smart home, while Members can only use “basic” device controls, like watching the live view of a security camera. However, admins can grant Members additional privileges by giving them “Settings” access, allowing for control over device and home-wide settings. Admins can also turn on “Activity” access so Members can keep tabs on device history and recent events, such as a visitor picked up by a doorbell camera.
Google is also simplifying the process of adding a child under 13 to the Home app. Once you set up your kid with a Google account through Family Link, you can invite them to your Google Home, which will add them as a Member by default.
The previous process involved using either Family Link, Google Home, or Google Assistant settings to add your child’s voice to your smart home before inviting them to your home, and many users struggled to get it to work. It seems Google is now streamlining the process by letting you invite a child to your home through the Google Home app, so long as you add them to your Google family group.
The former Irish national swimming coach George Gibney has been arrested in the United States.
Mr Gibney is wanted in the Republic of Ireland to face more than 50 historical sexual abuse charges.
He left Ireland more than 30 years ago and has not been back since.
He was arrested in Florida on Tuesday afternoon by US Marshals on foot of an Irish extradition warrant, according to Irish broadcaster RTÉ.
He is being detained pending a court appearance in the US. He can decide whether to accede or contest his extradition.
In a statement to BBC News NI, An Garda Síochána (Irish police) said it is “aware of the arrest of a male aged in his 70s in the United States on foot of an Irish international arrest warrant”.
“As this is currently a matter for the US authorities, An Garda Síochána will not be commenting further at this time.”
RTÉ is reporting that gardaí reopened an investigation into Mr Gibney after a number of people made allegations against him on the BBC podcast Where is George Gibney five years ago.
The criminal investigation was commenced in 2020 by a specialist team within the Garda National Protective Services Bureau. A file was sent to the Director for Public Prosecutions (DPP) three years later.
The DPP examined the file and recommended that Mr Gibney be charged with more than 50 alleged offences.
RTÉ also reported that An Garda Síochána secured an extradition warrant in the High Court seeking Mr Gibney’s extradition. Gardaí have been working with US authorities for more than six months.
Mr Gibney was a coach at Trojan swimming club in Dublin.
He was also a former Irish national swimming coach.
Maigret is the first contemporary television adaptation of Georges Simenon’s beloved novels about the streetwise Parisian Chief Inspector Jules Maigret.
Benjamin Wainwright (Belgravia: The Next Chapter, Lord of the Rings: War of the Rohirrim) stars as Jules Maigret, who heads the elite police unit known as La Crim, responsible for investigating all serious crime in and around Paris. Maigret is an unconventional young detective with something to prove, relentless in his investigations, chasing and a matchless knowledge of Paris and its inhabitants.
Stefanie Martini (The Gold, Last Kingdom, Emerald City) stars as Madame Louise Maigret. Blake Harrison (World on Fire, I Hate Suzie Too), Reda Elazouar (Sex Education, Pirates), Kerrie Hayes (The Responder, Criminal Record), Shaniqua Okwok (The Flatshare, It’s a Sin) and Rob Kazinsky (Star Trek: Section 31, Eastenders) make up the “Les Maigrets,” Maigret’s loyal team of detectives, with Nathalie Armin (Showtrial, Juice) as Prosecutor Mathilde Kernavel.
Maigret premieres on Sunday, October 5, 2025 at 9/8c on MASTERPIECE on PBS.

An enormous shadow hovers over the characters in “Jurassic World: Rebirth,” and it’s the same one that has been dogging composer Alexandre Desplat ever since he was a teenager in Paris.
That shadow? The music of John Williams.
“He’s such a legend for all of us,” says Desplat, 63, on a Zoom call from London, where he’s been burning the midnight oil on the score for Guillermo del Toro’s upcoming “Frankenstein.” “He’s just the only one to follow.”
Like Williams, Desplat is now a grizzled (though painterly handsome) veteran himself, with hundreds of films to his name. He’s already completed three scores this year alone — for the French-Swedish Palme d’Or nominee “Eagles of the Republic,” Wes Anderson’s “The Phoenician Scheme” and this week’s “Jurassic” heavyweight.
He’s also making his North American conducting debut on July 15 in a grand survey of his film career at the Hollywood Bowl, a fitting, if overdue, coronation of his two-decade reign as an A-list composer in America.
When Desplat began scoring Hollywood films in the early 2000s, his music swept in like a breath of fresh French air — elegant, restrained, melodic, idiosyncratic — and the list of filmmakers who sought him out reads like a sizable section of the Criterion Closet: Terrence Malick, Ang Lee, Kathryn Bigelow, David Fincher, Jonathan Glazer, Greta Gerwig.
“He’s the last tycoon of American movie music,” Desplat said in 2010 of his idol John Williams. “He drew a line and we just have to be brave and strong enough to try and challenge this line. With humility, but with desire. It’s a kind of battle.”
(Jennifer McCord / For The Times)
His ride-or-die partner is Anderson, who first employed him on “Fantastic Mr. Fox” in 2007 and who teed up Desplat’s first Oscar win with “The Grand Budapest Hotel.” (He’s been nominated eleven times.) May’s “The Phoenician Scheme” marked their seventh collaboration.
“As I started being a film composer, I had my idols in sight — of course Hitchcock and Herrmann, David Lean and [Maurice] Jarre, [François] Truffaut and Georges Delerue,” Desplat told me in 2014. “All these duets were strong and they showed how important the intimacy between a director and a composer would be for both of them. It’s not only good for the film, it’s good for the composers, because these composers actually developed their own style by doing several movies with the same director.”
In a town too often filled with generic, factory-farmed scores, his were like a gourmet French meal, even though he grew up on the same diet of American movies and their iconic scores. The young Desplat was obsessed with U.S. culture — listening to jazz, watching baseball and the Oscars — and he decided he wanted to score movies after he heard “Star Wars” in 1977. Emblazoned on the cover of that iconic black album were the words “Composed and Conducted by John Williams.”
“That,” Desplat told his friend at the time, “is what I want to do.”
It’s fitting and kind of funny that two decades after charming audiences with a delicate, waltzing score for the 2003 Scarlett Johansson prestige picture “Girl with a Pearl Earring,” the composer is now promoting a stomping monster score for a blockbuster behemoth starring Johanssson and a bunch of CGI dinosaurs — and tampering with John Williams’ sacred musical DNA.
“Jurassic World: Rebirth” isn’t the first time he’s had to brave the T-rex-sized footprints of his hero: Desplat scored the final two films in the “Harry Potter” series, and he was also the first composer on “Rogue One: A Star Wars Story.” He left the latter when Tony Gilroy took over the project from original director Gareth Edwards, and before composing any notes.
“I went as far as the change of directors and change of plans,” Desplat explains, “and the weeks passing by, and then I had to move on because I wanted to work with Luc Besson” (on 2017’s “Star Wars”-esque “Valerian and the City of a Thousand Planets”).
“I dreamed of writing for symphonic scores,” Desplat says, “but for many years there was no way I could do it in French cinema, because the movies didn’t offer that, or the producer didn’t offer that. I had to learn how to sound big with very little amount of musicians.”
(Jennifer McCord / For The Times)
Much like his work on “Harry Potter,” Desplat’s odes to Williams in “Rebirth” are more whispers than shouts — though there are a handful of overt declarations of both the iconic anthem and hymn for Steven Spielberg’s 1993 dino-masterpiece. More subtle homages arrive in his use of solo piano and ghostly choir, and in the opening three notes of his motif for the team led by Johansson’s character — a tune that almost begins like Williams’ “Jurassic” hymn.
“So there’s a connection,” Desplat says. “I take the baton and I move away from it.”
He composed new leitmotifs for wonder, for adventure, for danger. His score, much like the original, is an amusement park ride full of sudden drops, humor and family-friendly terror, with a few moments of cathartic, introspective relief.
Mostly, Edwards kept pushing him for more hummable motifs.
“When I was tempted to go back to something more abstract — you know, French movie,” Desplat says, winking — “he would just ask me to go back towards John Williams’ inspiration of writing great motifs that you can remember and are catchy.”
Desplat worries this is becoming an extinct art in Hollywood. “I don’t hear much of that in many movies that I watch,” he says. “It’s kind of an ambient texture — which is the easiest thing to create.”
In college, he would listen to the “Raiders of the Lost Ark” score on a loop, and as his own scoring career developed, he was paying keen attention to John Williams’ more intimate chamber scores like “The Accidental Tourist” and “Presumed Innocent” — as well as juggernauts like “Jurassic Park.” Besides the music itself seeping in, he learned that it was important to score every kind of film, no matter how big or small. Williams’ work also taught him “that I could have something elegant, classical, but with some seeds of jazz in the chords or in the way the melody evolves.”
Whenever he hears someone talking dismissively about Williams, Desplat gets defensive. “I want to punch them,” he says, only half kidding.
“He’s the master, what can I say?” Desplat told me in 2010. “He’s the man. He’s the last tycoon of American movie music. So that’s everything said there. He drew a line and we just have to be brave and strong enough to try and challenge this line. With humility, but with desire. It’s a kind of battle.”

When Desplat received his first Academy Award nomination, for “The Queen” in 2007, the one person who called from Los Angeles to congratulate him was Maurice Jarre, composer of “Lawrence of Arabia” and “Doctor Zhivago.”
Desplat had met the French legend a few times over the years, including an early invitation to a mixing session for the 1990 film, “After Dark, My Sweet.” Desplat was aghast when he saw director James Foley taking away Jarre’s melody and all the various musical elements on the mixing board, save for a simple electronic thump.
The young composer expressed his dismay and Jarre calmly said: “It’s his film. I have to accept that.”
“That’s a lesson that I learned very early on,” Desplat says. “I’ve never forgotten that, because it’s still the same,” he laughs.
He was also warmly received as a young man by Georges Delerue, the great serenader of the French New Wave in films like “Jules and Jim” and “Contempt.” “They were so kind,” Desplat says, “such sweet men, both of them.” (Michel Legrand? Not so much, Desplat says: “He said awful things about me in books.”)
What they all have in common — besides a penchant for composing beautiful music — is the defiant, transatlantic leap from the French film industry where they started to the highest perch in Hollywood. Jarre left Paris in the early 1960s after the enormous success of “Lawrence” and never looked back, forging meaningful partnerships with directors like Peter Weir and Adrian Lyne. Delerue uprooted from Paris to the Hollywood Hills after winning his first Oscar in 1980 and scored a few hits including “Steel Magnolias” and “Beaches.”
“I really think that people who work a lot are lazy,” says Desplat, who has already completed three scores this year. “That’s why they work a lot — otherwise they wouldn’t work at all.”
(Jennifer McCord / For The Times)
Desplat started professionally in France in 1985 and wrote roughly 50 scores before “Girl with a Pearl Earring,” the English-language film that put him on Hollywood’s radar. He continues to do French films amid the summer blockbusters and American art house pictures.
“I dreamed of writing for symphonic scores,” Desplat says, “but for many years there was no way I could do it in French cinema, because the movies didn’t offer that, or the producer didn’t offer that. I had to learn how to sound big with very little amount of musicians.”
He enjoys the freedom of a big-budget project. “To be able to have a studio say, ‘Go, write what you need to write.’ The director, he wants an orchestra, he wants 95 musicians. Great! They don’t even say anything. You just go and you record. They book the studio. They book the musicians.”
Still, the limitations he trained under gave Desplat some of his greatest strengths: creativity, resourcefulness, speed. He had to orchestrate everything himself, which means his music bears a distinctive fingerprint. And composing for small, sometimes unorthodox ensembles gave his music a clean, transparent signature as opposed to the all-too-typical wall of mud.
He can’t say much about his 100-minute score for “Frankenstein,” which he just finished recording with a giant orchestra and choir at both Abbey Road and AIR Studios, and which comes out on Netflix in November. The reason he does so many films, Desplat proposes, is because he’s lazy.
“I really think that people who work a lot are lazy. That’s why they work a lot — otherwise they wouldn’t work at all.”
USD/JPY hits four-week low of 142.68, but rebounds as US jobs and ISM data support the Greenback.
Powell keeps hawkish tone, saying July rate cut not guaranteed; RSI signals limited bullish momentum.
Key support lies at 143.00 and 142.11; resistance capped near 144.50–145.35 Ichimoku cloud zone.
The USD/JPY posted mild losses of 0.17% after hitting a new four-week low of 142.68, sponsored by upbeat economic data in Japan. However, good US jobs and business activity data, along with a hawkish Fed Chair Jerome Powell, lent a lifeline to the US dollar, which staged a comeback versus the Japanese Yen (JPY). At the moment, the pair trades at 143.77.
USD/JPY Price Forecast: Technical outlook
The USD/JPY remains neutral-to upward biased if the pair remains above the May 27 swing low of 142.11. However, upside movements could be capped by strong resistance at the bottom of the Ichimoku Cloud (kumo) at around 144.25-50. This, along with the Relative Strength Index (RSI) remaining bearish, suggests that consolidation lies ahead.
For a bullish case, the USD/JPY must clear 144.50, and the confluence of several moving averages, such as the 20- and 50-day SMAs. Once surpassed, the next area of interest would be the Kijun-sen at 145.07, ahead of the Tenkan-sen at 145.35. A breach of the latter will expose the 100-day SMA at 146.32, followed by the June 23 high of 148.02.
On the other hand, if USD/JPY falls below 143.00, a further downside is expected to occur, with a potential target of 142.00.

Today, Crucial has sent over their brand new T710 2TB Gen5 NVMe SSD for review. This is the successor to the very fast Crucial T705 that I previously reviewed. Like that drive, the T710 is making a play for the high-end Gen5 SSD market and intends to push the limit of the Gen5 interface, and Crucial is claiming some big performance uplifts from the T705. The high-end market space now has ample competition, so I am interested to see how the T710 holds up. Let us get to the review!
Crucial T710 2TB PCIe Gen5 NVMe SSD
The Crucial T710 2TB comes in a single-sided M.2 2280 (80mm) form factor.
Crucial T710 2TB Front
The T710 is available both with and without a heatsink, and as you can see my test drive is the bare drive. The controller is a key difference compared to the T705. The T710 includes a Silicon Motion SM2508 controller, whereas the T705 was based on a Phison chip. This controller is paired with Micron TLC and a 2GB DRAM cache.
Crucial T710 2TB Back
The backside of the Crucial T710 2TB contains nothing but labels.
Crucial T710 2TB SSD Specs
The Crucial T710 2TB is available between 1TB and 4TB capacity points.
Crucial T710 2TB Specs
This 2TB model is rated for 14500 MB/s sequential reads and 13800 MB/s writes. These numbers put the T710 at the top-end of claimed Gen5 performance and outpace both the T705 and the Samsung 9100 PRO, at least on paper. Endurance sits at 600TBW per 1TB of capacity, or 1200TBW for my 2TB drive which is perfectly in line with my expectations. And the warranty is the industry standard 5-years for a top-end drive. All of the specs position the T710 at the very top-end of Gen5 drives, and Crucial is also a very long-lived and respected brand.
Crucial is claiming 42% higher random writes, 28% higher random reads, and 9% higher sequential write performance compared to the T705. They are also claiming a 24% reduction in average power use. When we get to testing we will see how the two stack up.
Crucial T710 2TB CrystalDiskInfo
CrystalDiskInfo can give us some basic information about the SSD and confirms we are operating at PCIe 5.0 x4 speeds using NVMe 2.0.
Test System Configuration
We are using the following configuration for this test:
Motherboard: MSI MAG X670E Tomahawk
CPU: AMD Ryzen 9 7900X (12C/24T)
RAM: 2x 16GB DDR5-6000 UDIMMs
Our testing uses the Crucial T710 2TB as the boot drive for the system, installed in the M.2_1 slot on the motherboard. This slot supports up to PCIe Gen 5 x4. The drive is filled to 85% capacity with data, and then some is deleted, leaving around 60% used space on the volume.
Next, we are going to get into our performance testing.

The dates for the Clásicos in La Liga for 2025/26 have been revealed after the league calendar was revealed on Tuesday 1 July. The games in the league will take place on 25/26 October and 9/10 May as part of the 38 game La Liga season and are always the most eagerly awaited clashes of the campaign.
The first game between FC Barcelona and Real Madrid will take place at the Santiago Bernabéu on the weekend 25/26 October, following a fixture against Girona in week 9 of the league campaign and before a clash with newly promoted Elche in week 11.
The return fixture will take place on the weekend of the 9/10 May.
4 Clásico wins last season
Barça took victories in all four Clásicos last season on their way to the domestic treble. The first win came 4-0 away at the Santiago Bernabéu in the league, the second a 5-2 victory in the Spanish Super Cup, the third a famous 3-2 extra time win in the Copa del Rey final and the quarter was rounded off by a vital 3-2 at Montjuïc in La Liga.
On November 14, 2003, astronomers spotted what was at the time the most distant known object orbiting the Sun. They called it Sedna after the Inuit goddess of the ocean. It’s a cold, reddish dwarf planet that drifts billions of miles away from the Sun during its 10,000-year orbit before coming in for a relatively close approach to our star. Its next perihelion is happening in July 2076, and astronomers want to take advantage of this rare encounter by flying a mission to the mysterious object.
A team of researchers from Italy suggests mission concepts that could reach Sedna in seven to 10 years using cutting-edge technology. In a paper available on the pre-print website arXiv, they illustrate two experimental propulsion concepts that involve a nuclear fusion rocket engine and a new take on solar sailing technology. The propulsion technologies could cut down travel time to Sedna by more than 50% compared to traditional methods of space travel, allowing scientists a unique opportunity to gather clues about the early formation of the solar system and probe the theoretical Oort Cloud.
When it was discovered, Sedna was around 8 billion miles (13 billion kilometers) from the Sun. (Pluto, the most famous dwarf planet, has an average distance of 3.7 billion miles from the Sun.) Sedna is known as a Trans-Neptunian object, a group of objects that orbit the Sun farther out than Neptune. It has an extremely eccentric orbit: at its farthest distance, Sedna is 84 billion miles away from the Sun, or 900 times the distance between Earth and our star. During its closest approach, Sedna will be around 7 billion miles away from the Sun, nearly three times farther than Neptune. That’s still far, but it’s close enough for a spacecraft to reach the celestial object before it fades back into ultra-distant darkness.
Spacecraft have traveled farther distances before. Voyager 1 and 2 started their interstellar journey in 1977 and have traveled 15 billion miles and 12.7 billion miles thus far. It took Voyager 2 around 12 years to reach Neptune. Based on current technology, scientists estimate it would take around 20-30 years to reach Sedna during its closest approach, while using Venus, Earth, Jupiter, and Neptune as gravity assists. That would mean the launch window to reach Sedna is fast approaching, with no clear plans yet in place.
Instead, the researchers behind the new study suggest alternative methods to get us there faster. The first is the Direct Fusion Drive (DFD) rocket engine, which is currently under development at Princeton University’s Plasma Physics Laboratory. The fusion-powered rocket engine would produce both thrust and electrical power from a controlled nuclear fusion reaction, providing more power than chemical rockets.
“The DFD presents a promising alternative to conventional propulsion, offering high thrust-to-weight ratio and continuous acceleration,” the researchers write in the paper. “However, its feasibility remains subject to key engineering challenges, including plasma stability, heat dissipation, and operational longevity under deep-space radiation.” They add that, while advances are being made for fusion-based propulsion, it’s still unclear whether it can support long-duration missions and provide power for onboard instruments.
The second concept builds on existing solar sail technology, which is still experimental in its own right. Solar sails are powered by photons from the Sun, harnessing energy produced by light and using it to propel spacecraft forward. The researchers suggest coating the solar sails with material that, when heated, releases molecules or atoms and provides propulsion in a process known as thermal desorption.
The solar sail, assisted by Jupiter’s gravity, could reach Sedna in seven years due to its ability to continuously accelerate without the need to carry heavy fuel, according to the paper. The idea does come with its own set of challenges. “While solar sailing has been extensively studied for deep-space applications, its feasibility for a Sedna mission requires assessment in terms of long-duration structural integrity, propulsion efficiency, and power availability for science operations,” the paper reads.
Despite a slight time advantage, the solar sail mission would only allow for a flyby of Sedna, while the DFD engine could insert a spacecraft into the dwarf planet’s orbit for a longer mission. Either mission would provide us with the first direct observations of the previously unexplored region and help scientists better understand the larger boundary that houses the solar system.
