    Fighters On The Rise | Noche UFC

    A teammate and training partner of headliner Diego Lopes, the 29-year-old Brazilian earned a victory on Season 6 of Dana White’s Contender Series, edging out Juan Andres Luna by split decision in the opening week, which is better known as the “Be Joe Pyfer!” Week. After another regional circuit win, “Nono” was called up on short notice to face Amir Albazi, giving a good account of himself before getting stopped in the third, and has been on the roster ever since. He’s gone 2-1 over his last three fights, sandwiching a decision loss to Steve Erceg between stoppage wins over Jimmy Flick and Kevin Borjas to elevate his record to 14-4 overall.

    Costa is one of those fighters whose talents far exceed what his UFC record may otherwise suggest, as a quick glance shows you a .500 fighter, but losing to a pair of Top 10 mainstays — including one that gave the champ a real run for his money last year — speaks volumes about his overall skills and place in the divisional hierarchy.

    Tune-In Information For Noche UFC And Canelo vs Crawford

    Coria steps up to replace Edgar Chairez, carrying a 10-3 record with one no contest and a four-fight unbeaten streak into his promotional debut on Saturday in San Antonio. He trains out of the 4oz. Fight Club in Houston, home base for UFC veteran Daniel Pineda and top flyweight contender Joshua Van, so you know he’s had some quality rounds in preparation for this moment.

    Things feel more wide open in the flyweight division at the moment than they have in a while, and Costa has an opportunity to make a further push towards the rankings if he can add another victory to his resume this weekend in Texas. We’ve seen a host of names force their way into the Top 15 over the last year and a third win in four outings might just be enough to get Costa into position to face someone with a number next to their name next time out.

    Daniil Donchenko

    Though he’s had to wait almost a month to finally step into the Octagon for the first time, Donchenko remains someone to watch as he faces off with Rodrigo Sezinando in the finals of the Ultimate Fighter 33 welterweight tournament.

  • ‘Microbial piracy’ uncovers new way to fight drug-resistant infections

    Researchers have discovered how ‘pirate phages’ hijack other viruses to break into bacteria, sharing new genetic material for dangerous traits.

    Imperial scientists have uncovered how bacteriophages are able to hijack other viruses to break into bacterial cells and spread, through an act of microbial piracy which could potentially be harnessed for medicine.

    The discovery, published in the journal Cell, reveals a major route by which bacteria are able to acquire new genetic material, including traits that can make them more virulent or more resistant to antibiotics. The researchers believe it could also open the door to new ways of tackling the global threat of antimicrobial resistance (AMR) and developing rapid diagnostic tools.

    Phages (or bacteriophages) are viruses that infect and kill bacteria. They are among the most abundant organisms on Earth and are often highly specific, each tailored to attack just one bacterial species. Structurally, they resemble microscopic syringes: with a ‘head’ section packed with DNA and a tail section tipped with spiky fibres that latch onto bacteria and inject their genetic payload.

    But phages themselves are not safe from parasites. They can be targeted by small genetic elements known as phage satellites that hijack the phage’s own genetic machinery to propagate.

    In the latest study, Imperial researchers focused on a powerful family of phage satellites called capsid-forming phage-inducible chromosomal islands (cf-PICIs). These genetic elements can spread genes for antibiotic resistance and virulence, and are found across more than 200 bacterial species. Exactly how they managed to move so efficiently, however, was unclear.

    First discovered by the team in 2023, cf-PICIs can build their own capsids (the viral ‘heads’), but they lack tails, meaning on their own they produce non-infective particles – i.e. they are not able to infect phages. In their latest work, researchers at Imperial’s Centre for Bacterial Resistance Biology discovered the missing piece of the puzzle: cf-PICIs hijack tails from unrelated phages, creating hybrid “chimeric” viruses. The result is a chimeric phage carrying cf-PICI DNA inside their own capsids but a phage-derived tail attached.

    Crucially, some cf-PICIs can hijack tails from entirely different phage species, effectively broadening their host range. Because the tail decides which bacteria are targeted, this piracy gives cf-PICIs the ability to infiltrate new bacterial species, explaining their great abundance in nature.

    According to the researchers, the implications could be important for science. By understanding and harnessing this molecular piracy, researchers believe they could re-engineer satellites to target antibiotic-resistant bacteria, overcome stubborn bacterial defences such as biofilms, and even develop powerful new diagnostic tools.

    “These pirate satellites don’t just teach us how bacteria share dangerous traits,” explains Dr Tiago Dias da Costa, from Imperial’s Department of Life Sciences. “They could inspire next-generation therapies and tests to outmanoeuvre some of the most difficult infections we face.”

    The Imperial team has successfully filed patents to further develop the work and hopes to begin testing the translational applications of the technology.

    Professor Jose Penades, from Imperial’s Department of Infectious Disease, said: “Our early work first identified these odd genetic elements, where we found they are effectively a parasite of a parasite. We now know these mobile genetic elements form capsids which can swap ‘tails’ taken from other phages to get their own DNA into a host cell. It’s an ingenious quirk of evolutionary biology, but it also teaches us more about how genes for antibiotic resistance can be spread through a process called transduction.”

    Dr Dias da Costa, added: “This experimental work sheds more light on a crucial method of gene transfer in bacteria. If we can harness and engineer cf-PICIs it could provide us with a valuable new tool in the fight against antimicrobial resistance.”

    AI co-scientist tool
    In a linked project, coordinated through the Fleming Initiative – a partnership between Imperial College London and Imperial College Healthcare NHS Trust – researchers used their experimental work to validate a groundbreaking AI platform developed by Google.

    Dubbed the ‘co-scientist’, the platform is designed to help scientists develop smarter experiments and accelerate discovery.

    To test the platform, the Imperial team posed the same basic scientific questions that had driven their own work: How do cf-PICIs spread across so many bacterial species?

    Armed with this starting point, and drawing on web searches, research papers, and databases, the AI independently generated hypotheses that mirrored the team’s own experimentally proven ideas – effectively pointing to the same experiments that had taken years of work to establish, but doing so in a matter of days.

    The researchers say this shows the extraordinary potential of AI systems to ‘super-charge science’, not by replacing human insight, but by accelerating it. They are now working with Google to further develop the platform and explore how it could transform the pace of biomedical research.

  • Why humans matter most in the age of AI: Jacob Taylor on collaboration, vibe teaming, and the rise of collective intelligence

    Why humans matter most in the age of AI: Jacob Taylor on collaboration, vibe teaming, and the rise of collective intelligence

    Artificial intelligence dominates today’s headlines: trillion-dollar productivity forecasts, copyright lawsuits piling up in court, regulators scrambling to tame frontier models, and warnings that white-collar work could be next. Yet behind the headlines sits a bigger question: not what AI replaces, but what it can amplify.

    Jacob Taylor, once a professional rugby player and now a Brookings CSD fellow, argues that the 21st century may be less about machines outpacing us, and more about how humans and digital algorithms learn to work together. In this conversation, we explore how pairing human insight with artificial intelligence could reshape collaboration and help organizations large and small—from the World Bank to local NGOs—tackle complex global issues. And we ask, at the end, what it means to be human in the age of AI.

    Frankly, I think we’ll see that being human is going to matter more than ever in an age of AI. It’s going to force us to really clarify what being human really means. For the hopeful among us, it’s time to really speak out for what those human characteristics are.


    Jacob Taylor


    From the rugby scrum to the policy scrum

    Junjie Ren: Jacob, you’ve had one of the more interesting career arcs I’ve seen, from pro rugby to cognitive anthropology. Now you’re shaping how we think about collaboration itself. Let’s start with the thread that ties together performance, teams, and meaning. Tell us more about that.

    Jacob Taylor: I’m someone who’s been on an endless search for the holy grail of team performance. Athletes and other elite performers can feel when something bigger than them is happening, when the team is producing what no individual could achieve alone. I’ve also been in teams where the opposite has been true when performance has completely fallen apart.

    These experiences have driven my research into the science of team performance and collective intelligence. I spent several years doing ethnographic research with professional rugby teams in China, trying to figure out if and how formal models of group performance hold across cultures. Rugby served as a controlled field experiment. Watching vastly different teams across cultures playing the same game taught me a lot about constant and variable ingredients of human behavior and performance.

    Junjie Ren: How did that experience in China shape your view of how humans coordinate meaning across context, whether these teams are on the field, in policy rooms, or in digital ecosystems?

    Jacob Taylor: I learned that teams are ultimately very similar in their structure, but that structure plays out in different shapes and sizes in different cultures or contexts. Following my PhD research, my interest in China led me to do some policy work in Australia on multilateral trade and security cooperation in Asia. That all sounds a bit wonky, but for me, intuitively it became a question of: Where is the “team” in Asia? How can different countries in the region collaborate toward shared outcomes that align with—and maybe even exceed—the self-interest of all countries?

    One way to pair it back is to think about a canonical experiment in social psychology called the hidden profile task. In a small team of four to six people, each individual has a unique piece of information needed to solve a shared puzzle. For the team to solve the puzzle, each person must bring their piece forward into the team context, thereby surfacing the team’s “hidden profile.” International cooperation is rarely framed so explicitly in terms of performance or collective intelligence, but I believe this “hidden profile” logic of performance applies across scales, from sports teams to policymaking bodies to digital networks.

    Junjie Ren: What sparked your interest in AI and team collaboration?

    Jacob Taylor: In my PhD research, I applied new algorithms for understanding brain activity to model team interaction and performance. From there, I went to work on a DARPA (Defense Advanced Research Projects Agency) program developing an AI teammate, which drew me deep into the technical side of artificial intelligence and how it could be designed to enhance team performance and collaboration. That work shaped many of my current ideas on how to design both the technical systems and policy incentives needed to strengthen collective intelligence across scales.

    The hour of collective intelligence

    Junjie Ren: You’ve said that if the 20th century was the economists’ hour, the 21st may be the hour of collective intelligence. What do you mean by that?

    Jacob Taylor: It’s an idea that builds on a great book called The Economists’ Hour by New York Times journalist Binyamin Appelbaum. He charts how, in the second half of the 20th century, economists went from being largely absent from political conversations in the 1950 to becoming the primary evidence base for policymaking by the century’s end. That expertise was well-suited to the challenges nations and firms were facing then.

    But today, the issues we face are multidimensional and span communities of every scale. They can’t be solved by economics alone. Nor by law alone. Nor by any single discipline. What’s needed is a collective, transdisciplinary effort that draws on multiple evidence bases and scientific approaches. And that’s where the emerging science of collective intelligence comes in. It’s an unusually diverse field that includes computer scientists, social scientists, behavioral scientists, anthropologists, working together to understand how different mechanisms of collaboration and collective action can produce outcomes greater than any individual or institution could achieve alone.

    I see a real opportunity to pull these insights and innovations together, not only to inform policy and accelerate progress on issues embodied in the Sustainable Development Goals (SDGs), but also to advance other areas of human flourishing and societal value creation.

    Junjie Ren: You have been a driving force in the 17 Rooms initiative at Brookings. Tell us about the 17 Rooms approach, and specifically, how the “teams of teams” approach shifted your focus toward collective intelligence as a framework, or even a new science for solving global problems?

    Jacob Taylor: The basic premise embedded in 17 Rooms is that the world’s toughest challenges—from eliminating extreme poverty to preserving ecosystems, advancing gender equality, and ensuring universal education—are problems no single actor can solve alone.

    17 Rooms is a practical response to this challenge of how to catalyze new forms of collaboration that cut across institutions, sectors, and silos. It uses the SDGs to create a “team of teams” problem-solving methodology: Participants first gather into small teams, or “Rooms,” to collaborate on ideas and actions within an issue area. Proposals are then shared across Rooms to spot opportunities for shared learning and—where appropriate—shared action.

    So, 17 Rooms aligns perfectly with my intuition that change often boils down to people collaborating and connecting in small, mission-driven teams. And with the right infrastructure, it might be possible to scale teaming as a powerful unit of action for driving societal-scale outcomes.

    Why AI alone won’t save us

    Junjie Ren: AI now sits at the center of how we think about scaling ideas, innovations, decisions, or even creativity. How do you see AI both amplifying and complicating our ability to solve problems collectively?

    Jacob Taylor: Generative AI is exciting because it combines generalized intelligence with natural language capability. You can now just talk or type to a generative AI system and expect a legible response. This has drastically reduced the friction of human-machine interaction and massively lowered the barrier to human participation in AI systems. And because these models are generalizable, they can be applied to many different problems at once, offering huge potential for a full range of challenges facing people and planet.

    But there’s a big “but.” Realizing the positive societal impact of these technologies will depend a lot on how we design these systems and to what end. As I’ve written recently with Tom Kehler, Sandy Pentland, and Martin Reeves, for AI to work for people and planet—and not the other way around—we need to talk about AI as social technology built and shaped by humans and figure out how to use AI to amplify—rather than extract—human agency and collaboration.  The design choices we make today will determine whether AI strengthens collective problem-solving or deepens existing divides.

    Junjie Ren: Could you tell us more about the schisms or gaps you see in current AI discourse?

    Jacob Taylor:  Current AI conversations tend to split in two. One side is tech-first—focused on algorithms, frontier model capabilities, and conjecture around Artificial General Intelligence (AGI) and whether it will save us or take all our jobs. The other is policy-first—centered on risk and rights, aimed at protecting humans from AI’s harms. Both leave out the bigger question—and the bigger opportunity—which is how to combine human and artificial intelligence to unlock new forms of collective intelligence.

    Some colleagues of mine have suggested reframing generative AI as “generative collective intelligence,” or GenCI, because at its core, there’s a human story throughout. Foundation models are trained on the human collective intelligence embedded across the internet. They’re refined through reinforcement learning with human feedback, hours of human labor spent curating data, training, and conditioning these systems. Even after deployment, much of their improvement comes from ongoing human user feedback. At every stage, humans are part of the value chain.

    Yet, that story is not being elevated and articulated in public discourse or policy debate. If we position these frontier AI systems correctly, they can elevate and amplify human potential in teams, in organizations, and in communities. Yes, there may be labor market disruptions and creative destruction, but there’s also the possibility of new ways of working and expanding human potential. That’s the part of the conversation we need to develop and elevate with innovative approaches and the right policy incentives.

    When humans and AI team up: Vibe teaming defined

    Junjie Ren: Let’s shift to vibe teaming, a term you coined with Kershlin Krishna. What is it? How does it work in practice, and how does it differ from traditional prompt and response or copilot models?

    Jacob Taylor: Vibe teaming is a new approach to what we call human-human-AI collaboration. It’s a way to combine AI tools with human teamwork to create better outputs. In our case, we’ve been exploring its application to challenges embedded in the SDGs, asking: How could a new model of human-AI teaming help advance progress on something like ending extreme poverty globally?

    The idea came from “vibe coding,” a term popularized earlier this year by software engineer Andrej Karpathy. He described a workflow where he talks to an AI model describing the “vibe” of an idea for a software product and the model produces the first draft. The human expert then iterates on the first draft with the model—giving feedback on bugs or tweaks—until the product is complete. The process is quick, conversational, and low-friction, with the AI handling much of the lower-level work.

    We wondered: What if we did this collaboratively? So Kershlin and I sat down together in front of a phone, talked through what we wanted to create (in this case, a PowerPoint presentation) and ended up with a 20-minute transcript. We fed that into our AI model, and it quickly produced a draft presentation. That was the starting point for vibe teaming, and it felt like we were onto something.

    Pairing decades of human expertise with AI’s speed feels like a special sauce worth understanding.

    When world-class strategy takes hours, not years

    Junjie Ren: Walk us through a concrete use case—like the SDG 1.1 experiment with Homi Kharas?

    Jacob Taylor: We wanted to test vibe teaming on a real outcome, and we brought in our colleague Homi—a leading expert on global poverty eradication—and asked: What if we used this approach to design a global strategy for ending extreme poverty by 2030?

    In a single 90-minute session, we produced what we considered a “Brookings-grade” strategy—high enough quality to publish, which we did, along with a related blog. Our 17 Rooms team spent a fair amount of time thinking about what sequence of questions might get the most out of an expert conversation. Then the process was straightforward: start with rich human input, in this case a 30-minute recorded conversation with one of the world’s leading thinkers on global poverty. Feed that transcript into our customized AI models. Then engage in a careful, iterative process of human review and validation—you were part of that, Junjie—to refine the output for publication.

    The AI played a supportive role, handling tasks like transcription and first-draft generation, but the quality came from the depth of the human input and the decades of expertise behind it. Homi has been working in this space for over 40 years; we were drawing on his lifetime of insight and combining it with our own. Pairing that kind of wisdom with AI’s speed in iterating, automating, and structuring outputs feels like a “special sauce” worth understanding.

    Junjie Ren: What’s next for vibe teaming? Is it validation or scaling?

    Jacob Taylor: So far, we’ve had positive engagement with the approach—from AI teams at major U.S. automakers to government agencies around the world, and of course our colleagues here at Brookings, who are excited to experiment with this approach. We think it could become a practical tool for helping people integrate AI into the knowledge work they’re already doing.

    Since these initial tests, we’ve been exploring how to scale up and validate the approach in different contexts. On one hand, that means bringing more people into policy conversations to inform the strategies and outputs that come from processes like this. On the other, it means testing whether the method itself can be validated as a source of enhanced collaboration, creativity, and even team flow—relative to more individual work or other team formats.

    Why ‘team human’ still matters

    Junjie Ren: In policymaking spaces, where AI can already synthesize, summarize, and even simulate, what exactly is the role of humans?

    Jacob Taylor: There are a few parts to that. Big picture, what we were able to produce in 90 minutes (or a few hours total) was, by all accounts, world-class work. One of our Brookings colleagues thought it compared favorably with anything the World Bank has published on the topic. That raises big questions: If a small group of humans, plus AI, can produce something like this so quickly, what does that mean for large institutions and the traditional process of knowledge creation?

    This could signal an early disruption to policymaking. AI isn’t replacing knowledge creation, it’s an amplifier handling lower-level work (transcribing, drafting) so humans can focus higher up the value chain: judgment, collaboration, decisionmaking, brainstorming, creativity.

    That shift frees up capacity for the real game, which is building the architectures that let people work across silos, translate between institutional languages, and act collectively on big challenges. In our team’s anecdotal experience, through vibe teaming, we’re already spending less time buried in spreadsheets or documents and more time in conversation and quality control.

    Junjie Ren: What does success look like in practice when AI is a cognitive amplifier and not a replacement of humans?

    Jacob Taylor: Success is when we can measure human-AI collaboration actually improving collective intelligence. The science here is advancing fast. We can now identify causal mechanisms of collective intelligence in groups, ecosystems, and organizations.

    One simple framework breaks it into three components: collective memory (what we know together), collective attention (what we’re focused on together), and collective reasoning (what we have the potential to act on together). The question is: Can we use these factors to assess the outputs of human-AI systems? Can we say, “this collaboration increased our collective attention on a problem” or “this process expanded what we know together”?

    That’s the next frontier: tying experiments with these tools directly to measurable outcomes, especially on real-world challenges like the SDGs, so it’s not just novel process, but progress we can track and prove.

    Human embodiment and cognitive atrophy

    Junjie Ren: You’ve talked about cognitive atrophy as a risk. How do we guard against this trend in high-AI environments?

    Jacob Taylor: Obviously, with any new technology like this, humans and technology co-evolve, and cognition co-evolves. We are going to see atrophy in certain skills overall, and this is a particular risk for younger staff entering the workforce, or younger folks who are earlier in their skill development for knowledge work.

    But there’s also the opportunity to develop new cognitive competencies, skills, and attributes. Human-AI interaction—vibe coding, vibe teaming—is, over time, going to become a new muscle in itself, a bit like writing or reading, with its own set of commands. So there’s a balance to strike here: What needs protecting, and what we should lean into. In that spirit, I’m very much a “team human” kind of guy in the age of AI, and what is most human, meaningful, and core to us is our embodiment.

    Junjie Ren: Do you see embodied practices (such as Tai Chi, which you are known to lead at our staff retreats) having an active role in shaping how we design and interact with technologies like AI?

    Jacob Taylor: You know, the fact is that we’re in a physical body, and we use that to navigate the world, relate to others, and cultivate energy, creativity, and connection. I think that coming back, literally, to the in-breath and the out-breath that we as biological creatures have uniquely, and can share with others, is key to grounding the human ingredients in the AI story.

    Frankly, I think we’ll see that being human is going to matter more than ever in an age of AI. It’s going to force us to really clarify what being human really means. For the hopeful among us, it’s time to really speak out for what those human characteristics are. I think a lot of them are embodied in our most visceral, grounded practices that we enjoy together in community with others.

    One big takeaway

    Junjie Ren: Last question, if you were talking to a policymaker or an NGO leader or a CEO tomorrow, what is the one principle of vibe teaming you think they should try?

    Jacob Taylor: Yeah, there’s no free lunch. It’s the basic upshot with AI, I think. Humans shape the inputs and outputs of AI systems at every step. With this in mind, it’s so important to capture and elevate what makes us human—ingredients of shared purpose, story, motivation, and priorities—and build hybrid human-AI systems and tools with these ingredients as starting points.

  • Common Bathroom Habit Linked to 46% Higher Risk of Hemorrhoids, Study Finds

    Common Bathroom Habit Linked to 46% Higher Risk of Hemorrhoids, Study Finds

    If you like to bring your phone to the bathroom, you might be more likely to develop hemorrhoids. That’s according to a new study published in PLoS One, which found that people who used their phones on the toilet were 46% more likely to have this gastrointestinal condition based on colonoscopy results.

    Spending extra time sitting can restrict blood flow and compress the veins, increasing the risk of hemorrhoids.

    “The study is very timely, as cell phone use appears to be ubiquitous,” said Brian C. Jacobson, MD, MPH, a gastroenterologist with Massachusetts General Hospital and a spokesperson for the American Gastroenterological Association who wasn’t involved in the research. “It should be noted, reading any material on the toilet was also highly associated with hemorrhoids, so the issue is not smartphones per se, but spending additional time on the toilet,” he told Health.

    While you might think of hemorrhoids as something people develop, hemorrhoidal tissue is actually something everyone has. Made up of blood vessels, this tissue lines the anus and helps you sense pressure from gas or a bowel movement. 

    Hemorrhoids only become problematic when they swell, which can cause pain and bleeding. While some are external, occurring outside the anus, most are internal. Overall, hemorrhoids are common, with about 75% of Americans experiencing them at some point in their lives.

    Constipation was once thought to be the main culprit behind hemorrhoid disease, said Trisha Pasricha, MD, MPH, the new study’s senior author and a gastroenterologist at Beth Israel Deaconess Medical Center. Now, researchers believe the condition is more linked to straining and changes in pressure that affect hemorrhoid veins.“Over the last several years, our thinking about hemorrhoids has really evolved,” she told Health.

    While previous studies have examined how activities such as reading a newspaper on the toilet might affect hemorrhoid risk, the impact of cellphone use had remained an open question.

    To explore this, researchers analyzed the cellphone habits of patients visiting the Beth Israel Deaconess Medical Center for a colonoscopy. They surveyed 125 people, each at least 45 years old, about how often they used their phones while on the toilet, and then compared this to their colonoscopy results.

    The survey showed that 83 participants, or 66%, reported using smartphones on the toilet. This group was nearly seven years younger, on average, than those who didn’t use their phones, and they were less physically active overall. During colonoscopy, 43% of all participants had a visible hemorrhoid.

    After analyzing the data, researchers found that smartphone users and non-users had the “same levels of constipation, straining, and other factors, [but] the amount of time they’re spending [on the toilet] is very different,” Pasricha explained.

    While only 7.1% of participants who didn’t use smartphones spent over five minutes on the toilet, that was true for 37.3% of smartphone users.

    After accounting for risk factors like sex, constipation, straining, and BMI, the researchers concluded that smartphone users had a 46% higher chance of having hemorrhoids compared to non-users.

    The findings obviously have nothing to do with using cell phones—more to do with sitting on the toilet for long periods of time,” Waqar Qureshi, MD, a gastroenterologist and professor at Baylor College of Medicine, told Health

    But because the study wasn’t a carefully controlled clinical trial, it can’t determine whether this behavior—or something specific about cellphone use—actually causes hemorrhoids.

    The researchers say their findings should be validated in larger studies including people of different ages, especially since younger people appear to use cellphones the most. “We’re also planning a clinical trial where we’re trying to see how smartphone use actually impacts your physiology” and affects bowel movements, said Pasricha.

    Whether you’ve made a habit of scrolling while on the toilet, it’s important to pay attention if you notice blood in your stool or while wiping. It could be a sign of internal hemorrhoids—and it’s a reason to get checked out by a doctor.

    “Blood in the stool is something we never ignore in medicine, and so we want to make sure it’s not something else,” said Pasricha, such as more serious conditions like anal fissures or colorectal cancer. 

    Doctors use an endoscope to examine the inside of the anus and confirm whether someone has hemorrhoids. Internal ones can often be treated easily at the doctor’s office, while external ones may require surgery.

    To help prevent hemorrhoids, experts recommend:

    • Drinking lots of water
    • Getting enough fiber in your diet
    • Limiting straining on the toilet

    They also suggest trying to cut back on toilet time, period. “Leave the phone, and books and magazines, outside the bathroom,” Jacobson said. “Get back to them when you’re done.”

    WCH Tokyo 25 preview: men’s triple jump | News | Tokyo 25

    • Andy Diaz Hernandez seeking to add world outdoor gold to world indoor title
    • Olympic champion Jordan Diaz targets second successive global gold
    • In-form Jordan Scott and multiple medallists Pedro Pichardo and Hugues Fabrice Zango ready to challenge

    Italy’s Andy Diaz Hernandez will seek to add gold at the World Athletics Championships Tokyo 25 to the world indoor title he earned in Nanjing in March.

    The portents could hardly be better for him, as the national record of 17.80m he set to win in China is comfortably the best mark of the year so far.

    More recently, the 29-year-old won the Diamond League Final for a third time, jumping 17.56m in Zurich.

    Diaz Hernandez will know, however, that he can take nothing for granted against a field stacked with major medallists – some highly experienced, some swiftly up-and-coming.

    Diaz Hernandez took bronze at the Paris Olympics last year in a final won by the then 23-year-old Jordan Diaz, who won world U20 and Youth Olympic Games titles in 2018.

    By way of a Paris 2024 warm-up, Jordan Diaz won the European title in Rome with 18.18m, which put him third on the world all-time list behind Great Britain’s Jonathan Edwards on 18.29m and USA’s Christian Taylor on 18.21m. That eclipsed the challenge of Pedro Pichardo, who set a Portuguese record of 18.04m.

    Two months later in Paris, the Olympic final saw the two athletes occupying the same respective places.

    At 32, Tokyo Olympic champion Pichardo is seeking to add another world medal to gold he won in 2022 and his silvers from 2013 and 2015.

    Jordan Diaz has had a relatively quiet season so far and stands 15th on the world top list on 17.16m.

    In contrast, multiple Jamaican champion Jordan Scott has been in the form of his life this season. He has won at four Diamond League meetings, setting personal bests in three of them as he registered 17.27m in Xiamen, 17.34m in Oslo and 17.52m in Monaco, and he currently stands joint third on the 2025 top list.

    It is Melvin Raffin who shares that No.3 spot following the 17.52m PB he achieved at the French Championships last month. That mark added 32cm to his previous PB that was set indoors back in 2017 and will have been a big confidence boost from his final competition before heading to Tokyo.

    Second place on the 2025 top list is occupied by China’s Wu Ruiting, ninth at the 2017 and 2019 World Championships, who produced a huge personal best of 17.68 in Quzhou last month.

    Wu’s teammate Zhu Yaming – the Tokyo Olympic silver medallist, 2022 world bronze medallist and this year’s world indoor silver medallist – is joint eighth on the list with the mark of 17.37m he set in Quzhou.

    The gold, silver and bronze medallists in Budapest – respectively Burkina Faso’s Hugues Fabrice Zango and Cuba’s Lazaro Martinez and Cristian Napoles – all return.

    Like his contemporary Pichardo, Zango has been winning medals over a long span. Bronze medallist at the Tokyo Olympics, he completed his world medal set in Budapest having won bronze in 2019 and silver in 2022. This year he took world indoor bronze and he has a season’s best of 17.21m.

    Martinez and Napoles have respective 2025 bests of 17.12m and 16.90m, but have personal bests of 17.64m and 17.40m.

    Other contenders are Algeria’s Yasser Mohammed Triki, last year’s world indoor silver medallist, and Germany’s Max Hess.

    USA’s three-time Olympic and four-time world medallist Will Claye, who also has two world indoor titles on his CV, will compete at his eighth consecutive edition of the World Athletics Championships.

  • Strictly’s Thomas Skinner leaves press event early

    Strictly’s Thomas Skinner leaves press event early

    Skinner is known for signing off social media posts with “Bosh!”

    Strictly Come Dancing contestant Thomas Skinner has walked out of a press conference early ahead of the show’s launch later this month.

    The former Apprentice star and social media personality left the Elstree Studios event after talking to a group of journalists who were interviewing him alongside fellow 2025 contestant, Jimmy Floyd Hasselbank.

    Remaining journalists waiting to interview Skinner, including BBC News, did not get a chance to speak to the entrepreneur.

    Skinner has become a somewhat divisive figure – his motivational videos have attracted hundreds of thousands of followers since he left the Apprentice, but he has also attracted criticism in recent months.

    Some have taken issue with Skinner’s recent social media posts including one with a photo of himself meeting US Vice President JD Vance, and another of him wearing a Make America Great again cap.

    But many of his fans praise Skinner for what he describes as “standing up for traditional, hard-working, family values”, his patriotism, and campaigning on issues such as knife crime.

    Skinner and other Strictly contestants were taking part in a series of roundtable interviews, where celebrities meet with groups journalists for a few minutes at a time, in a style similar to speed-dating, to take questions.

    It’s unclear why Skinner made a quick exit before the session had ended, when he had not yet completed the full press circuit.

    Representatives for Skinner and Strictly Come Dancing have been contacted for comment.

    On Monday, Skinner took to X to had the “best day” after his first full day of rehearsals.

    One of the journalists at the table Skinner left told the BBC that the businessman had been fine when a fellow journalist asked him if JD Vance would be coming to watch him, jokingly responding that he thought the Vice President had more pressing things to do.

    All the contestants were interviewed in pairs or threes, with the exception of former Chelsea footballer Jimmy Floyd Hasselbaink, who was interviewed solo once Skinner had departed.

    Skinner first hit TV screens on The Apprentice in 2019, and has since appeared on shows including 8 Out of 10 Cats, The Wheel, Michael McIntyre’s Big Show, Good Morning Britain and Faking It, as well as Celebrity Masterchef.

    He is also known for his social media videos which encourage people to think positively, runs a number of small businesses, including a gym, and is a regular on TalkSport Radio.

    In response to criticism from some quarters, Skinner told The Daily Mail last month: “I’m not right wing.

    “People are like sheep and just started saying it because I got invited to go to BBQ with JD Vance and I posted a picture with him.

    “Who is gonna turn down an opportunity to meet the second most powerful man in the world?”

    ‘Beyond the pale’

    Earlier on Tuesday, BBC director-general Tim Davie defended the decision to cast former Skinner in Strictly, which starts later this month.

    Speaking to MPs from the Culture, Media and Sport committee, Davie said: “That was not my decision, that was the production team looking for those people … who want to do Strictly, and those people they thought would be interesting to the audience.”

    Davie added: “Clearly, we wouldn’t take anyone whose views are just beyond the pale, or we would see as completely unacceptable or not suitable, racist views, all those things, we wouldn’t accept them.

    “But that’s not the case here, from what I know, I’m not an expert on the individual, per se.”

    Earlier this week, the BBC announced premium-rate phone voting on Strictly would end, with viewers invited only to cast their votes for contestants online.

    Brian Lewis obituary | Publishing

    My friend Brian Lewis, who has died aged 88, was the founder in 1980 of Yorkshire Art Circus, a community publisher and arts organisation based in a converted school in Glasshoughton in West Yorkshire.

    Until 1997 Brian was also its full-time coordinator, leading a team of writers and community “enablers” who encouraged ordinary Yorkshire folk to value their own experiences and to commit them to print. Many of its scores of books were collections of memories and photographs from various contributors, but others were by lone authors, such as The Bus to Barnsley Market by Ian Clayton (1989), On Earth to Make the Numbers Up by Evelyn Haythorne (1990) and Chapati and Chips by Almas Khan (1993).

    Under the motto “Everyone has a story to tell. We find ways of helping them tell it”, the Art Circus often took a bold, experimental approach to assembling its publications. In 1988, for example, Brian and a team of writers based themselves in Scarborough library, where they asked borrowers for their memories of seaside holidays. They started collecting material in the morning, edited the interviews, and had The Bumper Book of Beanos ready for publication by the time the library closed. Apart from making books, the Art Circus also arranged art and photography exhibitions.

    Brian himself was an accomplished artist, with his mainly figurative painting often focusing on trade union events and history. His work was regularly exhibited at solo and group exhibitions across West and South Yorkshire and found its way into private collections in Canada, the US, Germany and India.

    In addition he wrote poetry that was published in three books, The Waters of Birmingham (1997), The Flight to Derry (2002) and The Ghost Walk (2006), as well as two novels, The Sexy Bits of Lady C (2015) and A Hesitant Woman (2016). He was Birmingham’s first poet laureate from 1996 to 1997, helping to raise the profile of poetry across the city, running workshops and mentoring other would-be and existing poets.

    Born in Smethwick in the West Midlands to Ernest, a poster writer, and Ada (nee Lines), a shopworker, Brian left James Watt technical school to become an apprentice in a foundry, before doing national service at RAF Topcliffe near Thirsk in North Yorkshire.

    After moving to Pontefract with his first wife, Jean Barker, in the early 1960s, he did teacher training at Dudley Training College for Teachers and then worked as an English teacher at Royds school in Leeds. He later moved into teacher training at Scawsby College near Doncaster, High Melton College in Doncaster, Bretton Hall in Leeds and Sheffield University’s extramural department, before setting up Yorkshire Art Circus.

    After the Art Circus, he set up the Pontefract Press publishing company and was self-employed, editing and producing books – often on the interplay between art and economic development – for local authorities, housing associations and government agencies.

    He and Jean divorced in 1982 and he married the textile artist Reini Schühle the following year.

    She survives him, as do his six children, John, Vicki and Rachel with Jean, and Jake, Jess and Hannah with Reini, six grandchildren and a great-granddaughter, Rowan, who was born in the early hours of the day Brian died.

    WCH Tokyo 25 preview: women’s triple jump | News | Tokyo 25

    • World record-holder Yulimar Rojas entered to defend her title in first triple jump competition since 2023
    • Leyanis Perez-Hernandez tops world list in 2025
    • Thea LaFond, Shanieka Ricketts and Jasmine Moore on the hunt for more major medals

    From 2017 to 2023, the women’s triple jump was dominated by Venezuela’s Yulimar Rojas. The world record-holder is entered to defend her title at the World Athletics Championships Tokyo 25, but the past two years have not gone to plan for the eight-time global gold medallist.

    Rojas claimed a record fourth world triple jump crown in Budapest thanks to a last-gasp leap beyond 15 metres, but she was unable to compete at last year’s Olympic Games in Paris due to an achilles injury. She was also forced to withdraw from her planned comeback meeting last month, but seems determined to line up in Tokyo – in what would be her first triple jump competition since winning her third Wanda Diamond League title in Eugene in September 2023.

    Her return is highly anticipated, as it would see her compete back in the stadium in which she won her Olympic title in 2021, getting gold in Tokyo with a then world record of 15.67m.

    But right now, her competitive form is unknown, and while Rojas sits 62cm ahead of her rivals when it comes to personal bests – her world record now standing at 15.74m from 2022 – it’s Cuba’s Leyanis Perez-Hernandez who leads this year’s world top list.

    Perez-Hernandez, who claimed world bronze in Budapest, jumped 14.93m to win the world indoor title in Nanjing in March – a mark just five centimetres off her PB set in San Salvador in 2023. She has also jumped 14.92m and 14.91m outdoors this year and has achieved five of the top six winning marks. Her victories have included Diamond League meeting wins in Oslo and Brussels and at the Diamond League Final in Zurich.

    Her compatriot Liadagmis Povea has a PB – set in 2021 – that matches Perez-Hernandez’s 2025 best and Povea sits second on the world top list with 14.84m jumped in Brescia in July. The Olympic fourth-place finisher – who finished one spot ahead of her compatriot in Paris – will be looking to go at least one place better and make the podium in Tokyo.

    Three other athletes with 15-metre-plus PBs star on the entry list, and they filled the podium places in Paris.

    Thea LaFond became Dominica’s first Olympic medallist when she got gold in Paris with a national record of 15.02m. Jamaica’s Shanieka Ricketts secured silver and USA’s Jasmine Moore claimed bronze, five days before earning a medal of the same colour in the long jump. They will all clash again in Tokyo.

    Ricketts is second on the world rankings behind Perez-Hernandez, with her results including Diamond League wins in Doha and Rome, where she finished ahead of LaFond and Perez-Hernandez, respectively. Her season’s best of 14.64m was set in Rome.

    Moore also has a Diamond League win to her name, but that came in the long jump in Silesia. She was third in the triple jump in Oslo and Brussels and has a season’s best of 14.68m, set when retaining her US title. Tokyo will be the first global outdoor championship in which Moore has focused on a single event – rather than doubling in the long jump and the triple jump – since the Tokyo Olympics.

    LaFond, who added her Olympic title to the world indoor gold she won in 2024, has a season’s best just two centimetres off that mark – 14.62m. She was second in Doha and finished fourth at the Diamond League Final.

    Others to watch include Jamaica’s three-time NCAA gold medallist Ackelia Smith, Slovenia’s Neja Filipic and Germany’s Caroline Joyeux, who has added 68cm to her PB this year, surpassing 14 metres for the first time in Essen in June, when she soared 14.45m. She has broken the barrier in three competitions since, her performances including 14.42m in Madrid.

  • Lithium levels tied to Alzheimer’s disease and dementia

    Lithium levels tied to Alzheimer’s disease and dementia

    September 9, 2025

    At a Glance

    • Levels of lithium were significantly reduced in the prefrontal cortex of people with mild cognitive impairment and Alzheimer’s disease (AD).
    • In a mouse model of AD, a low-dose lithium salt in the diet reversed memory loss and prevented cognitive decline in aging mice.
    • While more study is needed, lithium replacement could be a potential approach to prevent and treat AD.

    Compared to mice with normal levels of lithium in the brain (left column), mouse models of Alzheimer’s disease have increased levels of amyloid beta deposits (top right) and tangled tau protein (bottom right).

    Yankner Lab

    The brains of people with AD have abnormal protein deposits called amyloid plaques and tau tangles. Despite much progress in understanding AD, there is still uncertainty about how the disease develops. Previous research has found that the balance of metals in the brain may play a role, but the nature of this role has been unclear.

    A research team led by Dr. Bruce Yankner at Harvard Medical School set out to explore how metal ions—charged atoms of metals—might affect brain function and AD. The researchers first looked at whether metals in the brain differed in those who have mild cognitive impairment (MCI) or AD. In MCI, which precedes AD, people have more difficulty thinking, remembering, and reasoning than normal for people their age.

    The scientists analyzed post-mortem brain samples to quantify 27 metals in certain parts of the brain. They compared levels from dozens of people with AD, with MCI, and with no cognitive impairment. The results were published in Nature on August 6, 2025.

    The team found significantly lower levels of naturally occurring lithium in the prefrontal cortex of people with MCI and AD. The prefrontal cortex, which controls memory and decision-making, is prominently affected in AD. None of the other metals were significantly altered in people with MCI.

    Prior studies suggested that metal ions may interact with amyloid plaques. So the researchers compared lithium in plaques with plaque-free regions in human brain samples. They found that lithium was highly concentrated in amyloid plaques, and that the amount of lithium in the plaques increased from MCI to AD. Lithium levels in plaque-free regions were also significantly reduced in AD samples. These results suggest that lithium is sequestered by amyloid plaques.

    The researchers next explored how lithium in the brain affected AD pathogenesis in mouse models by depleting it from the diet. AD mice fed a reduced lithium diet had significantly more amyloid plaque and tau tangles along with impaired learning and long-term memory. In aged mice without AD pathology, those fed a low-lithium diet showed increased levels of the plaque-forming amyloid protein and developed significant memory loss. Lithium depletion affected gene activity in major brain cell types.

    Next, the researchers tested whether replacing lithium might influence AD pathology. Lithium carbonate is used as a mood stabilizer to treat bipolar disorder. But the researchers found that it is highly attracted to negatively charged amyloid plaques. The team tested 16 different lithium salts to find an alternative and settled on the organic salt lithium orotate.

    The researchers tested lithium carbonate and lithium orotate in AD mouse models at low doses in drinking water. Treatment with lithium carbonate had little effect. But lithium orotate significantly reduced amyloid plaque burden and tau tangle accumulation. Lithium orotate also restored synapses and reversed memory loss in AD mice, yet lithium carbonate did not.

    Finally, the team evaluated whether dietary lithium could have a protective effect in normal brain aging. They found that low-dose lithium orotate prevented synapse loss and reversed cognitive decline in aging mice. Long-term treatment with lithium orotate did not show toxicity.

    “The idea that lithium deficiency could be a cause of Alzheimer’s disease is new and suggests a different therapeutic approach,” Yankner says. But, he cautions, “Before recommending lithium orotate, we need to determine the effective and safe dose range in people. We are planning a clinical trial of lithium orotate that will hopefully begin in the near future.”
