    Emma Raducanu loses to Barbora Krejcikova in Korea Open last 16

    Emma Raducanu missed three match points as former Wimbledon champion Barbora Krejcikova fought back to reach the Korea Open quarter-finals.

    British number one Raducanu will be left to rue a missed opportunity after losing 4-6 7-6 (12-10) 6-1 in two hours and 52 minutes.

    Raducanu served for the match at 5-3 in the second set, having led it 4-1, and held a match point in that game.

    However, Krejcikova broke Raducanu back and forced a tie-break – which Raducanu initially seemed to have dominated.

    After racing out to a 5-2 lead, Raducanu found herself with two match points on the Krejcikova serve, but could not convert and the former world number two held firm to force a decider.

    Krejcikova, ranked 39th in the world, saved two break points in the third game of the deciding set before reeling off five successive games to secure victory.

    The Czech will face world number two Iga Swiatek of Poland in the quarter-finals.

    Reigning Wimbledon champion and top seed Swiatek was a 6-3 6-2 winner against Romania’s Sorana Cirstea earlier on Thursday.

  • ‘Cataclysmic’ situation in Gaza City, UN official says, as Israeli tanks advance

    ‘Cataclysmic’ situation in Gaza City, UN official says, as Israeli tanks advance

    Reuters Smoke rises following Israeli strikes in Gaza City (18 September 2025)Reuters

    The situation in Gaza City is “nothing short of cataclysmic”, a UN official has told the BBC, as Israeli tanks and troops continue to advance on the third day of a ground offensive.

    Olga Cherevko, a spokeswoman for the UN’s humanitarian office, said she had seen a constant stream of Palestinians heading south during a recent visit to the city, but that hundreds of thousands remained.

    The World Health Organization (WHO) warned that overwhelmed hospitals were on the brink of collapse because it was being prevented from delivering lifesaving supplies.

    The Israeli military said its forces were “dismantling terror infrastructure and eliminating terrorists” in Gaza City.

    It has said its objectives are to free the hostages still held by Hamas and defeat up to 3,000 fighters in what it has described as the group’s “main stronghold”.

    However, the offensive on Gaza’s biggest urban area, where one million people were living and a famine was confirmed last month, has drawn widespread international condemnation.

    The UN and its humanitarian partners have recorded at least 200,000 people crossing from northern to southern Gaza since mid-August, when Israel announced its intention to conquer Gaza City. Around 55,000 have made the journey since Sunday.

    Cherevko, who works for the UN humanitarian office in the central city of Deir al-Balah, told the BBC she travelled to Gaza City two days ago – a 29km (18 mile) round-trip that took 14 hours.

    “The things there, and the scenes on the way to Gaza City, are nothing short of cataclysmic,” she recalled.

    “A constant stream of people [are] crossing from the north to the south, many on foot. Inside Gaza City, it’s very crowded still because there are hundreds of thousands of civilians still remaining there.”

    She said she also witnessed multiple Israeli strikes “very close” to the UN convoy while in Gaza City, adding: “It was really just a constant hit after hit while we were there.”

    On Thursday morning, witnesses told Reuters news agency they had seen Israeli tanks in the northern Sheikh Radwan neighbourhood and the southern neighbourhood of Tal al-Hawa, which have come under heavy bombardment in recent days.

    They also reported that Israeli forces had blown up remotely driven vehicles laden with explosives in both areas, destroying many houses.

    Local hospitals said at least 14 people had been killed by Israeli fire across the Gaza Strip on Thursday, including nine in Gaza City.

    The Israeli military said in a statement that its troops were “expanding” their operations in the city, without giving any details about their movements.

    At the start of the ground assault on Tuesday, the military’s chief of staff, Lt Gen Eyal Zamir, told troops to “intensify the blows against Hamas and to decisively defeat the Gaza City brigade, in order to carry out the most moral and important duty – the return of all the hostages home and the dismantling of Hamas’s military and governing capabilities”.

    Cherevko warned that many people were unable to comply with the Israeli military’s order to evacuate to its designated “humanitarian area” in the south.

    “The expense of moving your belongings, if you are lucky enough to find a vehicle that will move them, is exorbitant. It’s not affordable for many people. And that’s why many are doing this on foot, with barely a mattress in their hands and maybe a plastic bag.”

    And once they arrived there were no guarantees of shelter or safety, she added.

    “I spoke to a lot of people who have recently arrived in Deir al-Balah and [the southern city of] Khan Younis. Many of them are sitting on the side of the street, with nothing. They don’t have any shelter. They don’t know where to go.

    “Yesterday, I met a family who had been walking around for four days, trying to find space to sleep and they didn’t manage,” she said.

    Many displaced families who have fled southwards are having to sleep on roadsides

    The WHO’s chief, Dr Tedros Adhanom Ghebreyesus, said the Israeli offensive was “forcing traumatised families into an ever-shrinking area unfit for human dignity”.

    “The injured and people with disabilities cannot move to safety, which puts their lives in grave danger,” he wrote on X.

    “Hospitals, already overwhelmed, are on the brink of collapse as escalating violence blocks access and prevents [the] WHO from delivering lifesaving supplies.”

    The UN says there are currently about 1,790 in-patient hospital beds for the 2.1 million population of Gaza, resulting in occupancy rates of 180 to 300% across the 17 hospitals that remain partially functional across the territory.

    Ten of those hospitals are in Gaza City and one is elsewhere in northern Gaza.

    On Tuesday, al-Rantisi children’s hospital in Gaza City – the only specialised paediatric hospital left in the territory – was hit by three Israeli strikes, causing damage to rooftop water tanks, electrical and communication systems and some medical equipment, according to Gaza’s Hamas-run health ministry.

    Forty patients fled for safety following the attack, while 40 others, including four children in the intensive care and eight newborn babies, remain inside.

    The Israeli military has not yet commented.

    The UN Population Fund meanwhile warned that women were being forced to give birth in the streets, without hospitals, doctors or clean water.

    The Israeli military launched a campaign in Gaza in response to the Hamas-led attack on southern Israel on 7 October 2023, in which about 1,200 people were killed and 251 others were taken hostage.

    At least 65,141 people have been killed in Israeli attacks in Gaza since then, according to the territory’s health ministry.

    The ministry says another 435 people have so far died during the war as a result of malnutrition and starvation, including four over the past 24 hours.

  • ‘New Journey of Healing’ for Traumatic Injury Patients

    ‘New Journey of Healing’ for Traumatic Injury Patients

    LOS ANGELES (Sept. 18, 2025) — Danielle Brown lay crumpled on Sunset Boulevard with a brain injury, no memory, no teeth, two broken arms, a broken leg and multiple other fractures.

    After her moped was mowed down by an SUV 14 years ago, Cedars-Sinai trauma surgeons spent weeks rebuilding her body. As for rebuilding her life, Brown continues to do that on her own. Brown’s role as a peer support volunteer in Cedars-Sinai’s new Trauma Survivors Network, helping others healing from physical trauma, is the newest part of that recovery.

    The Trauma Survivors Network, a program of the American Trauma Society, connects survivors and educates and empowers patients and their families during recovery. At Cedars-Sinai, Brown and a team of other volunteers connect with patients to listen, share, encourage and reassure.

    “It’s a community,” said trauma educator Gregory Jones, RN, injury prevention and outreach coordinator for the Cedars-Sinai Trauma Program. “Going through physical trauma can feel isolating. We wanted to have Trauma Survivors Network programming here so patients can feel a broader range of support as they navigate healing and recovery, and to help them feel more connected.”

    Cedars-Sinai is one of only four Level I adult trauma centers in Los Angeles County, which means it provides the highest-quality care for every aspect of injury—from prevention and emergency lifesaving surgeries and clinical care, to rehabilitation. In 2024, more than 1,600 patients were treated at the medical center for traumatic injuries.

    A 2023 paper published in Trauma Surgery & Acute Care Open noted that while trauma care has significantly improved survival over the past 50 years, continued struggles with disabilities, emotional challenges and brain injuries are common for many.

    With this in mind, Jazmin Perez, a clinical social worker in the Jim and Eleanor Randall Department of Surgery, ensures trauma patients and survivors are aware of Trauma Survivors Network resources—information about recovery, inpatient and outpatient support groups, and peer visitation opportunities.

    “We also check in with patients after they’ve been discharged from the hospital to see how we can continue to help,” Perez said. “Healing continues long after they get home, so making sure they feel supported and a sense of belonging is vital.”

    Improving the patient experience and fostering a sense of community is a key goal of the Trauma Survivors Network; another, Jones said, is connecting survivors with the providers who cared for them.

    “We want to introduce survivors to their first responders, as well as reconnect them with their trauma team,” Jones said. “We want these providers to be reminded of how much what they do matters.”

    More Awareness for Trauma

    Trauma Survivors Network volunteer Louise Lund experienced debilitating injuries in 2024.

    One minute she was driving home from work; the next, emergency responders were removing her through her car’s roof. Lund was unconscious, with a shattered hip, pelvis and sternum, 12 broken ribs, and a paralyzed leg. A driver had sped through a red light at more than 90 miles per hour, hitting Lund directly in the driver’s side.

    She had five nine-hour surgeries in five weeks and was at Cedars-Sinai nearly three months. As her body healed, there were unexpected symptoms to manage—hair loss, which she learned is normal after trauma, and the more common signs of post-traumatic stress disorder.

    She recalls a lonely road to recovery filled with uncertainty and sorrow, as well as a realization that the road also represented a path toward healing and hope. Today Lund is eager to assure patients they are not alone.

    “I want to bring more awareness to what happens to a person not only physically, but mentally,” Lund said. “Being able to say to people recovering, ‘Your resilience is your superpower,’ is part of my new journey of healing.”  

    Representation for Survivors

    It was a full-circle moment when Corentin Villemeur, another Trauma Survivors Network volunteer, recently picked up his official volunteer jacket. He was hospitalized in 2018 after he was hit by a drunk driver while walking across the street. He felt well-supported during recovery, but at the same time, no one had been through what he had.

    “It’s comforting to know you’re not the only one,” he said.

    The Trauma Survivors Network also gives Villemeur the opportunity to express gratitude.

    “I’ve struggled with how to say thank you to Cedars-Sinai in a meaningful way,” Villemeur said. “The providers don’t always get to see all the good work they’ve done. I’m back to nearly 100%, and I want them to see how my hard work and their hard work paid off.”

    Jones commended the Trauma Survivors Network volunteers, saying, “They had a dynamic life before their injury, and they’re able to share how they’ve reclaimed that life. They’re even stronger now, and they’ve opted to come back and help us help others—which is what Cedars-Sinai is all about.”

    Stronger now, Villemeur—who once feared he would no longer be able to stand—is back to Latin dancing and distance running.

    Stronger now, Lund is walking on her own again.

    Stronger now, Brown can enjoy playtime with her young daughter.

    “For a long time,” Brown said, “I was trapped in a body and life I didn’t recognize. Now I’m passionate about helping others also find the strength to keep going and come out on the other side with a life they love.”

  • NBA Fantasy: Rookies preview for 2025-26

    NBA Fantasy: Rookies preview for 2025-26

    Dylan Harper and Cooper Flagg headline the top NBA rookies entering the 2025-26 season.

    The 2025-26 crop of new players has numerous players who could pave their way into fantasy relevancy right away. Cooper Flagg is the jewel of the crown in this group, but there are several other first-year players bound to deliver strong fantasy value in 2025-26.

    Let’s discuss which rookies will emerge as fantasy contributors ahead of the 2025-26 NBA season.


    Cooper Flagg – Dallas Mavericks

    38th in Top 150 rankings

     

    Is there any other name to headline this list? Flagg is not only head and shoulders above the rest of the rookie class in terms of talent and upside, but he’s also expected to have sizable fantasy value from Day 1. Slated to open the season as the starting small forward for Dallas and with a proven ability to do a little bit of everything on both ends of the court, the sky is the ceiling for the former Duke standout.

    The numbers speak for themselves, as Flagg averaged 19.2 points, 7.5 rebounds and 4.2 assists while shooting 48.1% from the field and 38.5% from 3-point range during his lone season at Duke in 2024-25. Even though he’ll play in a loaded roster alongside Anthony Davis and Kyrie Irving (knee), Flagg should rack up defensive statistics and be a solid contributor across the board as a rookie, with the upside of becoming one of the NBA’s premier two-way players sooner rather than later. No other rookie in this class comes close to him in upside.


    Ace Bailey – Utah Jazz

    149th in Top 150 rankings

     

    A dynamic scorer who will hope to translate his offensive ability to the next level, Bailey is perhaps the most polarizing prospect in this class. Bailey played for Rutgers during the 2024-25 season and posted outstanding numbers, averaging 17.6 points, 7.2 boards, 1.3 assists, 1.3 blocks and 1.0 steals while shooting 46% from the floor and 34.6% from 3-point range over 30 games while featuring alongside Dylan Harper, who went second overall to the Spurs.

    No one doubts Bailey’s ability to score at will, and while he should eventually adjust and be a competent scorer at the NBA level, he needs to improve his decision-making in order to fully reach his potential. Fortunately for fantasy managers who decide to target Bailey, the Jazz are projected to be at the bottom of the Western Conference and should be fully committed to playing their young players through growing pains, meaning Bailey is likely to handle a big workload right out of the gate. That kind of floor and scoring upside makes him a valuable fantasy option in most formats, though in redraft leagues, he should be a mid-to-late-round pick at best.


    Kon Knueppel – Charlotte Hornets

     

     

    If Bailey is a polarizing prospect, Knueppel is one of the safest bets for sustained production outside of Flagg. The former Duke prospect averaged 14.4 points, 4.0 rebounds and 2.7 assists per game while shooting 40.6% from deep in his lone season in college. Knueppel is one of the best shooters in the draft and is considered to have an extremely high feel for the game, which should offset some of the defensive concerns around him.

    Still, most of the fantasy value he’ll provide will come from his excellent shooting ability, and he’s one of the best long-range shooters in this class. He figures to be a superb connector piece at the three between Brandon Miller and Miles Bridges, and his 3-point ability should allow him to thrive in fantasy regardless of the format.

    Fantasy managers would be wise to target Knueppel in late rounds, as he figures to be a starter right away on a rebuilding Charlotte team that could be on the rise in 2025-26. Knueppel has already demonstrated his potential, having been the MVP of the NBA 2K26 Summer League.


    Dylan Harper – San Antonio Spurs

    139th in Top 150 rankings

     

    From a talent perspective, Harper is considered the second-best player in this class behind Cooper Flagg, and it’s not even close. The Rutgers star averaged 19.4 points, 4.6 rebounds and 4.0 assists while shooting 48.4% from the floor and 33.3% from 3-point range in his lone year at the college ranks — and this was featuring Ace Bailey, who also had an extremely high usage rate. However, Harper might not find himself in the Spurs’ starting lineup right away, and even if he does, he’ll play alongside the two latest winners of the Kia Rookie of the Year award: Victor Wembanyama (2023-24) and Stephon Castle (2024-25).

    With De’Aaron Fox and Castle set to start in the backcourt, Harper might operate as a sixth man early on, but he might miss the start of the season while recovering from left thumb surgery. He’s still expected to have one of the best careers among rookies in this class, but in the 2025-26 season, he’s not going to be a steady fantasy option right away. He might be worth a flier in late rounds and deep formats, though he should have far more upside in dynasty formats.


    Khaman Maluach – Phoenix Suns

     

     

    A true seven-footer who still has room to grow and get stronger as he develops, Maluach is widely seen as one of the most high-risk, high-reward prospects in this class. Some believe he has All-Star upside, but if his offensive game doesn’t develop, he might end up being a situational rim protector.

    He’s going to open the season as a high-impact shot-blocker and a strong rebounder, but he’s not expected to begin his career in a starting role after the Suns acquired Mark Williams before the 2025 NBA Draft. If he develops a steady role in the rotation and manages to see close to 20 minutes per game, Maluach could be a solid fantasy option in category-based leagues and dynasty formats.

     

    Other rookies to consider:

    Egor Dëmin (Nets)

    Colin Murray-Boyles (Raptors)

    Noa Essengue (Bulls)

    Hugo González (Celtics)

  • NBA Birthdays: Players born on July 13

    NBA Birthdays: Players born on July 13

    Neemias Queta is among NBA players born on July 13.

    With over 5,000 players in NBA history, at least one player was born on every day of the calendar year – including four leap day ballers. Our day-by-day breakdown of the players born on each day of the year continues.

    Below are the most notable NBA players born on July 13.

    Frank Ramsey (1931)

    “The Kentucky Colonel” earned that nickname after a stellar collegiate career at the University of Kentucky, parlaying that into the sixth overall pick in the 1953 NBA Draft by the Boston Celtics. Ramsey spent his entire nine-year career with that organization, as he took one year off for military service in 1955, but that didn’t slow him down. Ramsey helped the Celtics win seven titles throughout his nine professional campaigns, averaging 13.4 points, 5.5 rebounds and 1.8 assists per game. That earned Ramsey a Hall of Fame induction in 1982.

    David Thompson (1954) 

    Many consider Thompson the greatest player out of NC State, carrying them to a 57-1 record and a national championship during his time there. That’s why he was the first pick in the 1975 NBA Draft by the Atlanta Hawks. However, he ended up signing with the Denver Nuggets of the ABA after the draft and transferred to the NBA with the Nuggets in 1976-77. Thompson was a presence immediately in his pro career, finishing second in MVP voting and winning ABA Rookie of the Year in his debut campaign while making his first of five All-Star appearances.

    Thompson finished top-ten in MVP voting in each of his first four seasons, making First-Team All-NBA in two of those. His best season was in 1978, averaging a career-high 27.2 points and 4.5 assists with 4.9 rebounds, 1.2 steals and 1.2 blocks per game. He closed his career with two years in Seattle before officially retiring in 1984. Thompson averaged 22.7 ppg, 4.1 rpg, 3.3 apg, 1.0 spg and 0.9 bpg throughout his nine-year career, earning him a Hall of Fame induction in 1996.

  • Read backs Black Ferns to tap into New Zealand’s ‘DNA and history’ in semi-final against Canada

    Read backs Black Ferns to tap into New Zealand’s ‘DNA and history’ in semi-final against Canada

    Kieran Read has backed the Black Ferns to tap into New Zealand’s ‘history and DNA’ ahead of their huge Rugby World Cup 2025 semi-final against Canada on Friday.

    The Black Ferns are on an unbeaten streak in Rugby World Cups that dates back to a pool-stage loss to Ireland in 2014. Since then they have swept all before them, winning the 2017 and 2021 tournaments. The New Zealanders are gathering the kind of momentum that saw them win four tournaments on the bounce between 1998 and 2010. 

    This year’s crop has their work cut out in a last-four clash with the best Canadian side ever assembled, but former All Blacks captain Read is backing his compatriots to take confidence from their previous victories.

    “The fact the history’s there now makes it something you want to live up to,” Read said. “That’s always been in the New Zealand rugby teams.

    “For them it’s making sure you can turn up and perform on the biggest stage. That requires a lot of skill but more so a lot of work on the mental game and handling what a World Cup does to you in terms of pressure.”

    The Black Ferns came into the tournament ranked third in the world, and as such had slightly less of a spotlight on them than usual. They started their Rugby World Cup 2025 campaign with solid victories over Spain and Japan, but since then have played some of their best rugby.

    A comfortable victory over Ireland in the final outing of the pool stage was followed by a slick quarter-final win against South Africa in Exeter – and Read says the way the Black Ferns are going about their business is cause for them to head into the semi-finals high on confidence.

    “They’ve improved from last year and even from the start of this year, watching them in the pool games,” he said. “Even in the quarter-final where they got put under a bit more pressure.

    “There’s certainly some great signs in there. Our DNA, the willingness to score some amazing tries has been evident. Man, they’ve scored some great tries.”

    While the razor-sharp focus of the team has impressed Read, so has the way they’ve conducted themselves on and off the field when interacting with opponents and fans alike.

    “You always see that from the women, it’s great,” he said. “I’ve got two daughters and it’s cool for them to see the girls out there playing with smiles on their faces.

    “Still going hard obviously and giving it their all on the field, but doing it with a smile on their face. It’s really inspiring actually.”

    Read and the rest of New Zealand will be hoping their players have more reason to smile than the Canadians come full-time at Ashton Gate. The 39-year-old knows all about these big games, having won back-to-back Rugby World Cups with the All Blacks in 2011 and 2015. 

    The legendary number eight says he hopes the Black Ferns are able to enjoy the special occasion and “embrace” the pressure of making it all the way to a sold-out final at Allianz Stadium next week.

    “Embrace the opportunities,” he said. “One reason you go over to World Cup is to give yourself a chance.

    “Right now there’s no point in holding anything back, it’s going out there and enjoying it the best you can and trying to earn yourself another chance at the next week.”

  • One Battle After Another Reflects World’s Extremism

    One Battle After Another Reflects World’s Extremism

    Paul Thomas Anderson‘s “One Battle After Another” has been met with some of the highest acclaim of the year. But the feature — described in Variety‘s review as a “mesmerizing vision of police-state America” — is more than just a crowd and critic pleaser.

    According to star Leonardo DiCaprio, who plays a paranoid ex-revolutionary living off the grid, the film reflects the increasingly polarized nature of today’s society.

    “It holds a mirror up to society and talks about the divisiveness in our culture and the fact that there’s so much polarity,” he told the BBC, adding that, while he didn’t think “One Battle After Another” has a central message, it features as “interesting undercurrent about extremism” and was “political without making it feel like medicine.”

    Also starring Sean Penn, Benicio del Toro, Chase Infiniti, Regina Hall and Teyana Taylor, the film is a black comic satire-meets-action blockbuster. The story is set in a U.S. that’s become a fascist police state where immigrants are rounded up and placed in detention centers and where a group of ragtag guerrillas attempt to disrupt the authoritarian regime.

    For DiCaprio, marking his first collaboration with Anderson, it also “finds the humanity in all the central characters,” despite their marked differences. “It’s about the people in the film and the characters — I’m a flawed protagonist — you can relate to them and their struggles and that’s not an easy thing to do.”

    Such has been the response, “One Battle After Another” has raced into contention for many as a sure-fire Academy Awards contender, following in the footsteps of Anderson’s previous films “Licorice Pizza,” which was nominated for three Oscars in 2022 and “Phantom Thread,” which landed six nominations in 2018, winning for best costume design.

    Of his director, DiCaprio said Anderson had “done a lot of films but in this one, he really went for it.”

  • Scientists create eco-friendly non-stick material for safer cookware

    Scientists create eco-friendly non-stick material for safer cookware

    From frying pans to raincoats, oil-repelling surfaces are everywhere. But the chemicals that make them slick, known as PFAS (per- and polyfluoroalkyl substances), have come under fire for their environmental and health risks. Now, a team of researchers at the University of Toronto Engineering may have found a cleaner way forward.

    Their newly developed material repels both water and grease just as effectively as traditional non-stick coatings, but with far less PFAS involved. That’s a big deal, considering PFAS are often called “forever chemicals” for their tendency to linger in the environment and accumulate in living organisms.

    Oil repellency isn’t just about keeping your shirt stain-free. It’s key to self-cleaning surfaces, anti-soiling fabrics, and protective coatings in industries like textiles, healthcare, and electronics. PFAS have long been the go-to for these jobs, especially the long-chain versions, which are now banned or restricted due to links with cancer, congenital disabilities, and other health issues.

    Short-chain PFAS are considered less harmful, but even they are under scrutiny. The problem? Few alternatives match their oil-repelling power.

    Scientists created an ultimate non-stick coating that can repel all forms of bacteria

    The Toronto team turned to polydimethylsiloxane (PDMS), a silicone-based material known for its biocompatibility. It’s often used in medical implants, but until now, it couldn’t match PFAS in repelling oil.

    To change that, PhD student Samuel Au developed a clever new technique called nanoscale fletching. Think of it like crafting a microscopic brush: short PDMS chains are bonded to a surface like bristles. Then, each bristle tip gets a tiny PFAS molecule, just one carbon and three fluorines.

    Zoom in to the nanometre scale, and the structure resembles the feathers at the back of an arrow, which inspired the name “fletching.”

    Oil-droplets
    This piece of fabric is coated with the new non-stick material made via the nanoscale fletching technique. The droplets being repelled are all low surface tension oils: from left to right: hexadecane, tetradecane, dodecane and decane. (photo by Samuel Au)

    To test their creation, the team coated fabric with the new material and dropped various oils on it. The result? A grade of 6 on the American Association of Textile Chemists and Colorists scale: matching many standard PFAS coatings.

    And because the PFAS used is so short, it doesn’t bioaccumulate like its longer cousins. That means similar performance with significantly lower risk.

    The researchers believe this hybrid material could be a game-changer for industries looking to ditch harmful chemicals without sacrificing performance. They’re open to working with manufacturers to scale up the process and are already exploring even safer alternatives.

    Their ultimate goal? A material that outperforms Teflon, without any PFAS at all. While that dream isn’t a reality yet, this breakthrough brings it much closer.

    In the world of non-stick science, tiny bristles and smart chemistry might be the key to a cleaner, safer future.
