NASA Artemis II Crew Rings Nasdaq Closing Bell 🇺🇸 NASA Artemis II Crew Rings Nasdaq Closing Bell NASA's Artemis II crew rang the Nasdaq closing bell on April 30, 2026. The event included astronauts from both NASA and the Canadian Space Agency. Jeremy Hansen, Reid Wiseman, Christina Koch, and Victor Glover stood together with Nasdaq's Chair and CEO Adena T. Friedman. This was not just a publicity stunt. They are set to fly around the Moon soon—though there's no exact date yet—and ringing the bell symbolized more than just marking time. There's this connection between space exploration and economic engines like stock markets which is strange if you think about it. 🇪🇸 El equipo de Artemis II toca la campana de cierre en Nasdaq El equipo de Artemis II de la NASA tocó la campana de cierre del mercado en Nasdaq el 30 de abril de 2026. Este evento reunió a astronautas tanto de la NASA como de la Agencia Espacial Canadiense. Allí estuvier...

18th-century mechanical volcano roars to life 250 years later 🇺🇸 Reviving Hamilton's Mechanical Volcano Picture this: two students at the University of Melbourne digging through dusty archives and stumbling upon an 18th-century watercolor. In it, a mechanical volcano imagined by Sir William Hamilton in 1775. Fast forward to today and these students have brought that very idea to life. Using LED lights and electronic systems, they've made Hamilton's vision erupt in glowing reds and explosive flashes. It's like Vesuvius without the danger or lava but with all the drama. Who knew old volcanic drawings could lead to such a show? This unexpected revival is not just about nostalgia; it's a nod to historical curiosity meeting modern technology. 🇪🇸 Renace el volcán mecánico de Hamilton Imagínate esto: dos estudiantes de la Universidad de Melbourne buceando en archivos viejos y encontrando una acuarela del siglo XVIII. En ella, un volc...

Deadly feline coronavirus variant has been present in the US for more than a decade 🇺🇸 Feline Coronavirus Variant Surfaces in the US Researchers at Cornell University stumbled upon something unsettling. Thousands of cats were dying due to a lethal variant of feline coronavirus over in Cyprus, but now it turns out that same strain has been lurking in the US for way longer. More than a decade. Which is strange if you think about it because no one noticed until all these cats started dying halfway around the world. How could something this deadly go undetected for so long? It raises questions about our surveillance on animal diseases right here. 🇪🇸 Variante de coronavirus felino detectada en EE.UU. Algo inquietante surgió del trabajo de investigadores en la Universidad de Cornell. Resulta que una variante letal del coronavirus felino, responsable por miles de muertes en Chipre, ha estado presente en Estados Unidos desde hace más de diez años. Nadie habí...

A Bit of Data Center Heat Can Be Turned Back into Electricity 🇺🇸 Turning Heat to Electricity Michael Abdelmaseh had this kinda wild idea. He looked at the heaps of heat spewed out by data centers and thought: hey, why not convert some of it into electricity? It sounds a bit like science fiction, if we're honest. But this is real stuff. Using the thermoelectric effect, he's trying to trap some of that waste heat and turn it back into something useful. I know it seems simple when you put it that way, but seriously, it's a whole process that involves specific materials and conditions. A discovery like this could actually change how we look at energy waste in tech. 🇪🇸 Convertir el calor en electricidad Michael Abdelmaseh apareció con la idea de convertir el exceso de calor de los centros de datos en electricidad reutilizable. Eso suena a ciencia ficción, ¿verdad? Pero es una propuesta real y concreta que utiliza el efecto termoeléctrico p...

NASA Kennedy Center Director Announces Plans to Retire [TITLEEN]Janet Petro's Retirement Announcement[/TITLEEN] NASA dropped some big news. Janet Petro, the woman at the helm of Kennedy Space Center for a while now, is stepping down. It's not every day you hear about someone with such a diverse background in military and industry making waves at NASA. This is the same Janet who started with them back in 2007. And then rose through the ranks to become center director. She's not leaving just yet, but announcing her plans to retire. You've got to wonder what sparked this decision — something personal or just time for a new chapter? [TITLEES]Anuncio de retiro de Janet Petro[/TITLEES] La noticia que arrojó la NASA es algo impactante: Janet Petro, quien ha liderado el Centro Espacial Kennedy, se retira. No todos los días se escucha sobre alguien con un trasfondo tan diverso en el ámbito militar e industrial causando impacto en la NASA. Ella come...

This “Pink Floyd” spider hunts prey 6x its size and lives in walls 🇺🇸 Pikelinia floydmuraria Meets the World Imagine naming a spider after Pink Floyd. The Pikelinia floydmuraria, it’s not your average wall-dweller. Researchers stumbled upon this tiny arachnid by observing its preference for urban walls, which is strange, if you think about it because why would a spider hang out there? Well, they don’t just hang out. They hunt and use those walls as strategic spots to catch prey much larger than themselves. Ants are their go-to meal—up to six times their size! Maybe it’s the lights nearby that attract the bugs they feast on, but no one's totally sure yet. 🇪🇸 Llega al Mundo la Pikelinia floydmuraria Imagina ponerle el nombre de Pink Floyd a una araña. Parece raro al principio, pero esa es la historia de la Pikelinia floydmuraria. Los investigadores la encontraron en las paredes urbanas y se sorprendieron de su habilidad para cazar insectos much...
