  • Novak Djokovic wins 99th match at Wimbledon, ladies’ champion Barbora Krejčíková progresses

    Novak Djokovic wins 99th match at Wimbledon, ladies’ champion Barbora Krejčíková progresses

    Novak Djokovic has shown signs he is easing into the old routine at Wimbledon, with the seven-time champion sauntering into the third round, while defending women’s champion Barbora Krejčíková has also made it through. 

    This year’s Championships have been littered with seeds biting the dust early, but day four offered some big statements from those fancied for deep runs on the lawns.

    • Day four Aussie wrap: Aussie caught up in Wimbledon farce, as Kasatkina and de Minaur win

    Former women’s champion Elena Rybakina may have arrived very much under the radar but has reached the third round for the loss of a mere seven games, the 11th seed destroying Greece’s Maria Sakkari 6-3, 6-1 in 62 minutes.

    Five-time grand slam champion Iga Świątek, surprisingly yet to go past the quarterfinals at Wimbledon, is another who will quietly fancy her chances and the Pole looked impressive as she hit back from a set down to beat Caty McNally 5-7, 6-2, 6-1.

    Djokovic struggled past Alexandre Müller on Tuesday when he struggled with stomach issues. Two days later, however, he was at his ruthlessly efficient best in a 6-3, 6-2, 6-0 thrashing of popular Briton Dan Evans on Centre Court.

    The 38-year-old is bidding to equal Roger Federer’s men’s record eight titles and claim an unprecedented 25th grand slam crown and, while the talk is of top seed Jannik Sinner and defending champion Carlos Alcaraz disputing the final, the Serb should be dismissed at your peril.

    He has reached the last six Wimbledon finals and clearly believes he will still be around on July 13.

    “Technically, tactically, I knew exactly what I needed to do and I executed perfectly,” Djokovic said after his 99th match win at Wimbledon since making his debut in 2005.

    “Sometimes you have these kind of days, where everything goes your way, everything flows and it’s good to be in the shoes and holding a racket on a day like this.”

    Czech Krejčíková, a surprise winner last year, found herself out on court two where the 17th seed produced a typically businesslike display as she battled past American Caroline Dolehide, winning 6-4, 3-6, 6-2.

    She will face a much more dangerous American next in the form of Emma Navarro after the 10th seed crushed Veronika Kudermetova 6-1, 6-2.

    With four of the top five women’s seeds already gone, the draw looks wide open for the likes of seventh seed Mirra Andreeva who beat Italian Lucia Bronzetti 6-1, 7-6(4).

    Nearly half of the 32 men’s seeds have perished before the third round with 13 failing to clear the first hurdle.

    Czech teenager Jakub Menšík, the men’s 15th seed, beat American Marcos Giron 6-4, 3-6, 6-4, 7-6 (7-4) to underline his credentials.

    Bulgarian Grigor Dimitrov, playing in his 59th successive grand slam, may no longer be considered a genuine title threat but more than a decade since reaching his sole Wimbledon semifinal showed he is still a class act as the 19th seed beat tricky Frenchman Corentin Moutet 7-5, 4-6, 7-5, 7-5.

  • Hong Kong Intervenes to Defend FX Peg for Third Time in a Week

    Hong Kong Intervenes to Defend FX Peg for Third Time in a Week

    Hong Kong’s de-facto central bank bought the city’s dollar again to defend its foreign-exchange peg, as two previous rounds of intervention failed to send funding costs high enough to dampen bearish currency bets.

    The Hong Kong Monetary Authority bought HK$29.6 billion ($3.8 billion) of the currency in New York trading Thursday, a move which drains liquidity from the financial system and can increase borrowing costs. The amount was higher than the HK$20 billion it purchased earlier this week and more than triple the HK$9.4 billion it purchased last week.

    The Motorola Razr Ultra 2025 is the company’s competitively priced foldable phone. You can pick one up with 1TB of storage for $1,300, which is $200 off the regular price and available in a variety of colors and finishes. If you prefer the Motorola Razr Plus 2024 model instead, you’ll find that starting at $799, again $200 less than the typical retail price. We spotted this same deal at Amazon right now as well, if you prefer to shop there.

    Hey, did you know? CNET Deals texts are free, easy and save you money.

    If the Motorola Edge lineup is more your style for a limited time, you can get the Motorola Edge 2024 for just $350 and the Motorola Edge Plus 2023 for $400, both deals reflecting a $400 savings. We also spotted the Edge 2024 for the same price of $350 at Best Buy.

    And for the most wallet-friendly phones, the Moto G phones make a great option. These already super-affordable phones are now even less, including the Moto G Power 5G 2024, which is $210 at Amazon or at Motorola, a price that falls $90 below the regular cost.

  • Wimbledon 2025: Why have record number of seeded players been eliminated?

    Wimbledon 2025: Why have record number of seeded players been eliminated?

    In a quarter of the women’s draw which included the eliminated Paolini and Chinese fifth seed Zheng Qinwen, American Amanda Anisimova has perhaps benefited most.

    The 13th seed would not face anyone ranked higher than 30th seed Linda Noskova until the semi-finals, where she could meet world number one Sabalenka – although the unseeded Naomi Osaka, a four-time major winner, remains in her quarter.

    In the men’s singles, Russian Karen Khachanov can reach the quarter-finals without facing a fellow seed, following defeats for Zverev, ninth seed Daniil Medvedev, 16th seed Francisco Cerundolo and former runner-up Matteo Berrettini.

    Norrie could also make it to the quarter-finals without encountering another seed, with Brazilian teenager Joao Fonseca or qualifier Nicolas Jarry awaiting in the fourth round if the Briton can first overcome Mattia Bellucci.

    Between 2002 and 2019, men’s singles seedings were determined by a surface-based formula reflecting recent grass court achievements, before it aligned with the world rankings used for the women’s draw.

    On whether the amount of early shocks this year provides a case for bringing that back, former world number five Durie said: “I do think there should be a consideration because grass is really unlike all the other surfaces. I think it was a good thing at the time. It would be interesting if they brought that back.”

  • New loofah-like polymer kills viruses, stronger than plastic

    New loofah-like polymer kills viruses, stronger than plastic

    A team of researchers at the University of Tokyo has created a new synthetic polymer inspired by the natural loofah sponge.

    The material is strong when dry, flexible when wet, and responds to pH changes, making it suitable for filtration and structural applications.

    Designed with sustainability in mind, this loofah-like polymer could transform how lightweight materials are used in electronics, construction, and medical devices.

    Filters viruses, responds to pH

    The porous material resembles a natural loofah in structure, but it wasn’t intended to look that way.

    “We developed a lightweight yet mechanically robust porous polymer, which resembles the fiber network of a natural loofah sponge. Though we did not set out to create something with such an appearance, it was a pleasant surprise,” said Associate Professor Yoshimitsu Itoh from the Department of Chemistry and Biotechnology at the University of Tokyo.

    The polymer’s pore network is fine enough to allow fluids to pass through while blocking bacteria and viruses. Importantly, it also kills the viruses it filters.

    That functionality, combined with its responsiveness to pH, becoming more rigid or flexible depending on acidity, makes it versatile.

    Some of the properties were inspired by real loofahs, which are dried plant husks, not plastic, as many assume.

    Like their natural counterparts, the synthetic version is stiff when dry and softens when wet.

    Itoh said the team aimed to mimic some of nature’s materials but with synthetic control to allow more functional variations. “So-called polymer materials like this already exist in nature, but we wanted to create something synthetic as it affords us control over its properties such that we can give it various useful functions.”

    The new polymer achieves impressive stiffness, up to 11 gigapascals, despite its low density of only 0.5 grams per cubic centimeter. According to Itoh, that’s four times stronger than typical polymers.

    “One drawback of lightweight polymers is their mechanical weakness — they tend to be very soft,” he said. “But ours is low density… but has a stiffness of 11 gigapascals.”

    This strength, paired with low weight and environmental safety, opens the door to using the material in devices where durability is crucial but mass must be minimized.

    The team says it’s made from a substance similar to lignin, a natural component found in wood.

    The polymer can also be coated onto other surfaces, expanding its use in manufacturing, especially where minimal raw material use is essential for sustainability.

    Thin films, zero post-processing

    The polymer’s production is simple. It uses pure water, applied voltage, and a mixture of resorcinol and an aldehyde. These ingredients combine to spontaneously form an ultrathin, porous membrane, with no extra processing needed.

    “One big advantage of this membrane is that there is no need for post-processing,” said Itoh. “Usually, thin films are made by first synthesizing the bulk polymer and then processing it into a film. Our method can directly give the product the form of a thin film and is, in principle, applicable to roll-to-roll processing.”

    The team is also experimenting with baking the membrane in an inert atmosphere to create a porous carbon version. This could pave the way for nanoscale electronic components like microcapacitors.

    While industrial use may still be years away, the low-cost and scalable nature of the process makes the innovation promising for future sustainable technologies.

    The study is published in the journal Science.

    Tennis, Wimbledon 2025: Exclusive – Brandon Nakashima finds rhythm on grass in pursuit of the next step

    Nakashima has beaten Bu Yunchaokete of the People’s Republic of China and fellow USA player Reilly Opelka, both in four sets, to make it to the round of 32. His previous best result came three years ago with a run to the fourth round in 2022.

    It helps that he feels right at home in London, making the most of his preparation week in the capital to walk the streets and explore. “I have a lot of close friends that live around here, so it’s always nice to see them,” he explains.

    Now firmly in his stride and with the all-important self-confidence, what else can the San Diego man produce in south-west London?

    Wimbledon 2025 – Brandon Nakashima’s growing grass game

    Growing up with Japanese and Vietnamese heritage in California, Nakashima has spent the last 20 years of his life on the tennis courts; naturally in the States, that means his favoured hard courts, but Wimbledon is his favourite tournament.

    The world number 34 went into the Championships 2025 with a 4-2 record on the surface this year, managing the rapidly forced adaptation from the classy clay swing into the condensed grass season.

    “It’s two completely different surfaces,” Nakashima explains, “the footwork, the speed at which you play, the tactics out there on the court too. I feel like we’ve handled the transition pretty well, I’m feeling more and more comfortable on the grass.”

  • Is Biometric Verification Must for Easypaisa, JazzCash transactions after new changes?

    Is Biometric Verification Must for Easypaisa, JazzCash transactions after new changes?

    ISLAMABAD – Biometric verification is becoming important for online transactions in Pakistan with rising concerns over identity theft, fraud, and misuse of government aid. Pakistanis using mobile wallet services need to make this from now onwards.

    State Bank of Pakistan rolled out new mechanism towards enhancing security of digital financial services, and all cash transactions must be conducted through mobile wallet platforms like Easypaisa and JazzCash. The new rule came into effect on July 1, 2025.

    EasyPaisa and JazzCash users will need to verify their identity via biometric authentication when making cash deposits or withdrawals at retail outlets across Pakistan to prevent fraud, strengthen user protection, and ensure that all transactions are safely and accurately processed.

    Is Biometric Verification Must For Easypaisa Jazzcash Transactions After New Changes

    The news sparked concerns among users as authorities clarified that no user accounts will be blocked and all funds remain secure. The biometric requirement solely applies to physical cash transactions conducted through authorized agents and has no impact on existing accounts or balances.

    Easypaisa and JazzCash agents are already in place to assist customers with their transactions. Any deposit or withdrawal made without biometric verification will not be processed under new rules.

    Biometric rule is said to introduce secure digital banking in Pakistan as Biometric verification not only adds an extra layer of security but also builds greater trust among users. The move could further accelerate Pakistan’s transition toward a more secure and cashless economy, especially as mobile wallet adoption continues to rise across urban and rural areas.

    With over 50 million active mobile wallet users in Pakistan, the implementation of biometric verification marks a significant milestone in the country’s digital financial landscape.
