Lee Kuan Yew explica como llevó a cabo un cambio cultura a la fuerza en Singapur: "fue dificil cambiar a una población que estaba acostumbrada a portarse como el tercer mundo...no podes mear y escupir en todos lados como hacias en la villa..."

If a vaccine injures your child, you can't sue the company that made it. They have a special legal shield no one voted for. My End the Vaccine Carve Out Act changes that.

Amazing! 😍 And that deep bass voice was the biggest surprise—so rich and powerful. #vocals #seashanty #acapella

Yale researchers have successfully restored cellular activity in mammalian brain hours after death. It challenges long-held assumptions about the finality of brain expiration. Yale University researchers have pioneered a groundbreaking system known as BrainEx, capable of restoring cellular activity in pig brains hours after blood flow ceases. By utilizing a specialized chemical cocktail and a dialysis-like machine, the team successfully revived neural and vascular integrity, demonstrating that cellular death is a gradual process rather than an instantaneous event. This discovery suggests the brain possesses a surprising level of resilience to oxygen deprivation, offering an entirely new perspective on biological preservation and the potential to protect tissue long after the heart stops. The research reached a new milestone by integrating a healthy liver into the system, which allowed brains to regain electrical activity 50 minutes after oxygen loss. While the study emphasizes that no consciousness, thought, or awareness was restored, the ability to maintain tissue functionality raises profound ethical questions regarding the clinical definition of death. These findings provide a critical foundation for future advancements in organ transplantation and neuro-resuscitation, though experts clarify that sensational claims of fully reviving consciousness or frozen brains remain unsubstantiated by current science. source: YaleNews.

A 2025 Nature study revealed a surprisingly simple way aspirin might help fight cancer metastasis. Researchers discovered that cancer cells trick blood vessels into releasing a substance called thromboxane A2 (TXA2). This chemical then sends a signal that basically tells our immune system’s T-cells to “stand down,” making it easier for cancer to spread. Science nugget: In mouse models of breast, skin, and bowel cancer, aspirin blocked TXA2 production. This freed up the T-cells to attack more effectively, resulting in significantly fewer metastases. When scientists genetically removed the key protein (ARHGEF1) that receives the signal, metastasis dropped sharply — and aspirin had no extra effect, proving this is the main pathway. The study helps explain why some earlier human observational data showed potential protective effects (especially for colorectal cancer). However, these promising results are still from mice, and experts stress that we need proper clinical trials in humans to confirm who might benefit and what the risks are. Any use of aspirin for cancer-related reasons should only happen after talking to your doctor, due to side effects like increased bleeding risk. It’s a fascinating reminder that an old, cheap drug might still have hidden powers we’re only beginning to understand. Does this aspirin-cancer connection surprise you, or does it make you curious about what other everyday medicines might have undiscovered effects?

🚨Japón 🇯🇵 Los ciudadanos japoneses quedaron atónitos cuando NHK, la emisora ​​nacional más grande de Japón, transmitió un informe completo de una hora de duración sobre los daños de la vacuna de ARNm contra la COVID-19. 🔥

Do you know about the Winny case in Japan? Isamu Kaneko, arrested in 2004, was not just the developer of a file-sharing program. He was one of Japan’s brilliant programmers. Winny was an advanced decentralized P2P network, far ahead of its time in Japan. While the world later embraced similar ideas in distributed systems, anonymous networks, and blockchain-era thinking, Japan focused only on its illegal use. Kaneko was dragged into a long legal battle and was finally acquitted in 2011. But by then, Japan had already lost the chance to protect and develop its own innovation. What Japan treated as dangerous, the rest of the world turned into value. If people like Kaneko had been protected instead of crushed, Japan might have become a global leader in decentralized technologies. Even after his acquittal, there was no visible accountability from the authorities who destroyed his future. Kaneko’s loss was not just the loss of one genius. It was Japan losing part of its future. #Japan #Winny #IsamuKaneko #Innovation #Technology #P2P #Decentralization

It doesn’t really matter who cleared the Amazon rainforest of its precious cargo of biological wonder, or why. What matters is the wave of destruction happening right now. We should care. Whether it’s illegal logging, cash crops or land-clearing for cattle - the biological result is the same: fragmented forests and stalled succession. The renewables industry likes to talk about PET foam and carbon fibre as a 'cure-all,' but the engineering reality is more graphic. PET often lacks the specific 'shear' strength and stiffness needed for the massive 100-metre blades deployed in harsh offshore environments. These blades are the size of a Boeing 747 - some are even longer. For these gargantuan structures, balsa remains the 'white gold' backbone of a crooked trade. In the 1970s, environmentalists would have gone bananas over this kind of industrial incursion into the Amazon. Now, they're largely silent - perhaps they are dazzled in the headlights of global warming ideology. They've forgotten what they once stood for. Sometimes, money and subsidies aren't the only things that matter. Orchestrated gangs and drug cartels are clearing the lungs of the earth to build turbine blades or carve secretive tracks through the jungle. Is this what today's silent environmentalist movement calls 'progress'?

She was elected to lead the Olympics as its first female president. Her first major decision: ban transgender women from women's events. Kirsty Coventry, a two time Olympic gold medalist in swimming from Zimbabwe, became the first woman to lead the International Olympic Committee in its 132 year history when she was elected president in June 2025. One of her first major decisions was launching a review of female category protections in Olympic sport. On March 26, 2026, the IOC Executive Board approved a 10 page policy banning transgender women from all female events at the Olympics starting with the 2028 Los Angeles Games. Eligibility is now limited to biological females verified by a one time SRY gene screening. Athletes who test negative are permanently eligible. The policy also restricts most athletes with differences in sex development, including two time Olympic champion Caster Semenya. Coventry said the policy protects fairness, safety, and integrity, adding that "even the smallest margins can be the difference between victory and defeat."

La biblioteca de la abadía de Admont, situada en Austria, es la biblioteca monástica más grande del mundo, una joya del arte barroco tardío terminada en 1776 por el arquitecto Joseph Hueber.

A newborn rhino calf named Daisy was found alone, just hours old, trembling and weak. Rescuers rushed her to intensive care, where she received round-the-clock treatment—but she was still missing something vital: a companion. Then came Modjadji, a tiny zebra foal rescued after storms left her barely alive. Both orphans had lost their mothers far too soon, but together they found comfort. What began as cautious curiosity grew into inseparable friendship. Now Daisy and Modjadji eat, play, and even sleep side by side—two survivors healing through each other’s presence. One day they’ll return to the wild, but for now, they’ve chosen each other as family. Sometimes, the family you choose is the one that saves you.

Rubén Blades, en una reciente entrevista con Mayka Navarro para La Vanguardia, cuenta que decidió escribir sus memorias por consejo de Gabriel García Márquez. Investigando un poco, encontré que efectivamente el libro ya está listo, Rubén plasmó parte de sus memorias en esta obra que él mismo escribió durante la pandemia y que originalmente tenía más de 500 páginas, las cuales tuvo que ir ajustando por solicitud de la editorial. Finalmente, el libro, que lleva el título ‘Life's Little Surprises: A Memoir’ (Las Pequeñas Sorpresas de la Vida: Unas Memorias), se encuentra en preventa en la página oficial de Amazon. Será publicado oficialmente por el Grupo Editorial Random House, uno de los más grandes del mundo, el próximo año, el 8 de junio de 2027. Hasta ahora, no se ha mencionado si habrá una versión en español; esperemos que sí. ¿Lo comprarás? 📚

This isn't just about just losing balsa trees, it's about illegal loggers dismantling the world's most precious biological architecture. Every tree is a self-contained ecosystem that evolved 350 million years ago, long before grass or flowers. Insects, birds and dinosaurs all relied on trees as the foundation of life on land. Luckily, Earth’s life-support system is vast. Between 50% and 70% of our photosynthesis takes place in the oceans via phytoplankton. But this oceanic engine room is not an excuse to justify the staggering cost of land-clearing for industrial-scale renewables, cash crops, farming or urban growth. You cannot protect the future by erasing the biological past. We must have climate policy rooted in reality, and not treat the Amazon wonderland as a hardware store for turbine parts.

Cuando era adolescente, esperaba con impaciencia el día en que llegaba a la biblioteca de mi barrio el nuevo número de mi revista favorita, @muyinteresante. Como no podía permitirme comprarla, la leía allí, página a página, saboreando cada artículo. Mentiría si dijera que soñé con escribir algún día un artículo para MUY, pero seguro que me habría hecho ilusión saberlo. Con la divulgación han llegado varios artículos, y el último me ha hecho especial ilusión: "La guerra de las corrientes: Edison contra Tesla", dentro de una edición monográfica de coleccionista dedicada al genio de Thomas Alva Edison. No os la perdáis, porque está repleta de artículos fascinantes y muy interesantes (valga la redundancia).

Chicago just opened a school with zero teachers. Not reduced. Eliminated. An AI teaches reading, writing, math. Two hours a day. One-on-one with a machine. Second graders spend the rest of the day running businesses. No teaching degree required. Bachelor’s minimum. Tuition: $55,000 a year. Your kid’s public school still can’t agree on homework policy. Who’s obsolete — the students, or the system?
