Gregg Popovich shares his final message and it has nothing to do with wins and losses. "The wins and losses are all crap. The highs and lows are all crap. It's illusory. It doesn't really exist." "What exists is seeing these guys and their kids. Those relationships with your assistant coaches - everybody else you're with - your colleagues, your friends." "'Cause that's what you take with you as you move along." The best leaders and coaches invest in people. "All those wins or losses - they fade away. They fade away." "But those relationships stick with you forever. And that's where the self-esteem and the self-satisfaction comes." A must-listen message for all coaches, players, parents, and teach out there. Great leadership isn't one style. It's knowing your people well enough to give them what they need. Invest in the relationships. Care about people, hold them to their potential, and lead in your style. (🎥NBA )

Sequential radiotherapy and immunotherapy (#iRT) provided longer overall survival than concurrent iRT for newly diagnosed advanced non–small cell lung cancer, with additional benefit from chemotherapy. ja.ma/4egGKt6

Never been diagnosed with terminal cancer? Then listen before you speak. Too often, people rush to offer advice, reassurance, or explanations for an experience they’ve never lived. Some realities cannot be understood from the outside looking in. Abigail (@AMJohnston1315) captured this truth beautifully: “People who have never carried that weight should approach it with great care and humility, not instruction manuals. Sometimes the kindest thing a person can offer is not advice, positivity, or correction, but silence sturdy enough to hold another person’s fear without trying to reorganize it into something more comfortable.” #WellMeaningAdvice #SilenceIsGolden #TerminalCancer #metastaticbreastcancer #bcsm

BREAKING🚨: A growing body of intelligence and law enforcement investigations suggests that Russia and Iran are increasingly recruiting teenagers across Europe to carry out acts of sabotage, espionage, and antisemitic violence. According to multiple reports, young people—some as young as 11—have been approached through Telegram, TikTok, Discord, gaming platforms, and other social media channels, often lured by cryptocurrency payments and promises of quick money rather than ideology. European security services describe the tactic as a new form of “hybrid warfare,” exploiting vulnerable youth as disposable proxies. Investigators have linked a series of attacks on Jewish schools, synagogues, charities, and community organisations across Europe to Iranian-backed networks and the militant group Harakat Ashab al-Yamin al-Islamia (HAYI), which is alleged to operate as a front for Iran’s Islamic Revolutionary Guard Corps (IRGC). Authorities believe many of the perpetrators were local teenagers or young criminals recruited online with little understanding of the wider geopolitical operation they were serving. Recent investigations have connected these networks to attacks in the UK, the Netherlands, Belgium, France, and elsewhere, while intelligence agencies warn that similar recruitment methods are also being used by Russian operatives. The concern has become so significant that the United States, Australia, the United Kingdom, and several European allies recently issued a joint condemnation of Iran’s alleged “lethal plotting” and covert operations on foreign soil. Security officials warn that hostile states are increasingly outsourcing terrorism, intimidation, and political violence to digitally recruited local actors, creating plausible deniability while spreading fear and instability. The message from counterterrorism experts is clear: modern conflict is no longer confined to battlefields—it is increasingly being fought through social media, criminal networks, and the manipulation of young people.

Civil disobedience: 1) Non-violently transgress a law you believe unjust 2) Accept the legal consequences 3) A public shocked by the harshness of the punishment forces changes in the law. Palestine Action: 1) Smash property and hurt people 2) Demand to be exempted from legal consequences 3) A public shocked by the violence of the crimes committed thinks, "actually these sentences seem rather light under the circumstances."
UK government's ban on Palestine Action is lawful, Court of Appeal says, overturning earlier ruling bbc.in/4uMempi

Everyone has been so impressed by Japanese fans cleaning up after themselves but most probably missed this beautiful moment at the post-game (🇳🇱2 - 2🇯🇵) press conference. Toward the end after reporters were done asking questions, 🇯🇵head coach, Hajime Moriyasu, asked to speak one more time. 🗣️ “May I speak?” He turned to the Dutch reporters in the room. 🗣️ “I think there are many Dutch reporters here as well, so I’d like to take this opportunity to express my gratitude to the people of the Netherlands once again.” Moriyasu explained that when he became part of the Japan national team, Japanese football still had no professional league. 🗣️ “I was trained by a Dutch coach named Hans Ooft. It wasn’t just me. Japanese coaches in general were greatly influenced by him, which has led to the development of Japanese soccer today.” He also mentioned another Dutch figure who shaped his career. 🗣️ “The legendary Dutch coach Wim Jansen served as the manager for J.League’s Sanfrecce Hiroshima and also as a coach for Urawa Reds, contributing to Japanese soccer.” 🗣️ “It’s not just those two. Many other coaches and players have contributed to raising the level of Japanese soccer, so I want to express my thanks. Thank you very much.” What a masterclass in graciousness and gratitude. Imagine after a high-stakes match, instead of basking in glory and bravado (well-deserved in my opinion), the coach took to the microphone to... thank his opponents publicly and sincerely. Japan's cultural operating system prizes harmony (wa), respect for precedent, and gratitude as a form of strength, not weakness. Japanese sports culture reflects its broader society where you'll see athletes bow to their opponents, thanking referees, and even crediting rivals or mentors. Think of sumo wrestlers, Olympic athletes, or even bullet-train staff apologizing for a 30-second delay. The Japanese have this concept of On (恩) - it is the sense of indebtedness to those who came before or helped you. It's what you'd expect from a culture that truly prizes continuity. Moriyasu was acknowledging a real debt to Dutch coaches like Hans Ooft (who coached Japan in the early 90s and helped professionalize the game) and Wim Jansen. Japanese football openly credits foreign influences - Dutch "Total Football" philosophy, German organization, Brazilian flair - while building something distinctly their own. Few nations do this with such little ego. Japan is pure class

In the 1980s, Massachusetts was headed for a water crisis. Through leak repairs, pipe replacement, efficient fixtures & public outreach, the MWRA cut water use dramatically. Today, Quabbin withdrawals average ~200mgd, the same as 1950. Boston uses less water than it did in 1900.

Karl Popper’s, ‘Open Society and Its Enemies’ remains one of the most compelling defences of open discourse as a civilisational mechanism of error correction. For Popper, Truth is never possessed in its entirety. It can only be understood through a logical process of criticism, disagreement, and the continual testing of ideas. A society that is capable of correcting its mistakes entirely depends upon the freedom to question prevailing assumptions and to expose falsehood through reasoned debate. It is therefore entirely regrettable that one of the more insidious realities of our age is that certain individuals and institutions invoke the language of the open society while inverting its essential principles. Under the banner of tolerance, safety, equity or consensus, group-think, they have deliberately narrowed the range of permissible inquiry and badly damaged the very processes through which truth is discovered. Popper understood that certainty is the enemy of progress. Indeed, a civilisation that loses its capacity for honest discourse loses its principal means of self-correction. Once criticism is treated as heresy and dissent as a threat rather than a necessity, the foundations of the open society begin to crumble from within. beg you to read Popper. To read @DavidDeutschOxf. To listen to and absorb the work of @ToKTeacher @naval @ConjectureInst and the many other great critical rationalists. We ought to understand the great peril we face.

Discovery of a 14-protein biomarker that predicts lung cancer 5.6 years before it is diagnosed, even in non-smokers, and an anti-inflammatory medicine that prevents its progression. And, challenging dogma, the proteins are not coming from cancerous cells!

1/5 An open letter to @TheLancet from an Iranian-Jewish cardiologist. Today, one of the world's most prestigious medical journals published a campaign to suspend the Israeli Medical Association from the World Medical Association — the body founded after WWII to ensure physicians would never again be weaponized by political ideology. I'm a cardiologist. I'm an Iranian Jew who grew up under a regime where medicine was subjugated to the state. What The Lancet just did is a disgrace to my profession. Here's what they published — and what they deliberately left out.

💭We treated the cancer. Now what? 📊 Long-term follow-up of 782 men ≤59 years treated with LDR brachytherapy demonstrated outstanding oncologic outcomes: ✅ 15-year biochemical failure: 4.9% ✅ 15-year prostate cancer-specific mortality: 1.8% Yet of the 114 deaths observed, only 14 (12%) were due to prostate cancer. ❤️ Cardiovascular disease (32%) and 🎗️ other malignancies (30%) accounted for most deaths. Notably, 🍬diabetes nearly doubled the risk of death, while current smokers🚬 had ~3x higher mortality than non-smokers. As prostate cancer outcomes improve⬆️, survivorship, cardiovascular health🫀, smoking cessation🚭, and management of comorbidities may be just as important as cancer control itself. advancesradonc.org/article/S… @ASTRO_org

Researchers increasingly believe the 40s, 50s and 60s represent a critical window for protecting cognitive health later in life, suggesting dementia is driven by years of metabolic stress, inflammation and vascular damage accumulating across the body. wapo.st/4ehdfaz
