Le pape Léon XIV imprime sa méthode, sans rupture avec l’héritage de François

Apaisant vis-à-vis de la curie, adepte d’un style plus formel sur la scène diplomatique, le souverain pontife américain renouera avec la tradition en passant par Paris et Lourdes, étapes boudées par son prédécesseur, avec qui il partage les mêmes vues sur l’environnement et les migrations.

While their husbands held talks at the White House, Melania Trump hosted Peng Liyuan at the Smithsonian National Museum of Asian Art on Thursday, where the famed Chinese soprano softly hummed along to a youth choir’s performance of a familiar classic. Footage shows the Hope Chinese School youth choir waving Chinese and American national flags during their rendition of the song “Jasmine Flower”, while Peng watches with a smile, her lips moving along to the lyrics. As the performance ends, she...

Trump autopen joke at Biden’s expense draws rare laugh from China’s Xi

Chinese President Xi Jinping broke into rare laughter as his US counterpart Donald Trump showed him a framed “autopen” displayed in place of the former American leader Joe Biden’s portrait during a White House tour. The viral moment stood out against the Chinese leader’s otherwise restrained demeanour during his first state visit to the United States in more than a decade. A video released by the White House on social media showed Trump taking Xi along the White House colonnade on Thursday...

De forma sorprendente, España es bastante más pro-IA que los países de su entorno

Ayer, mi compañero Jose García resumía en la newsletter de Xataka una de las contradicciones más llamativas del momento: "las empresas de IA han pedido frenar y, a los dos días, han lanzado tres modelos nuevos". La frase condensa bastante bien lo que estamos viendo. Mientras crecen las llamadas a ralentizar el desarrollo de los modelos más avanzados y aumenta la preocupación por sus riesgos , la industria sigue presentando nuevas herramientas y empujando sus capacidades un poco más lejos . La cuestión interesante aparece cuando trasladamos ese debate fuera de los laboratorios: ¿qué piensa la…

La URSS perforó un pozo de 12.262 metros en 1970: lo que detuvo las perforadoras no fue ni la roca ni el dinero

Sabemos bastante sobre lo que hay a miles de kilómetros sobre nuestras cabezas, pero llegar apenas unos kilómetros bajo nuestros pies sigue siendo extraordinariamente difícil. La Unión Soviética quiso comprobarlo de la manera más directa posible y en mayo de 1970 comenzó a perforar en la península de Kola con una meta que hoy todavía impresiona: descender unos 15 kilómetros dentro de la corteza terrestre . No era un pozo destinado a extraer petróleo ni a explotar una mina. Querían llegar donde nadie había llegado y observar directamente un mundo que, hasta entonces, conocíamos sobre todo…

Mexican EPICS in IEEE Team Builds Portable Educational Platform

In Guadalajara, Mexico, many high schools have motivated teachers and talented students with an interest in science, technology, engineering, and mathematics, but they lack access to advanced tools such as robotics laboratories. The resources shortfall limits the students’ opportunities for hands-on learning on cutting-edge applications. A team from ITESO, Universidad Jesuita de Guadalajara , is working to change that. Through the EPICS in IEEE initiative, a multidisciplinary group of 15 engineering students, faculty advisors, and IEEE Guadalajara Section volunteers developed RoboMeshA. The…

Measure Distant Asteroids With a DIY Rig

I’ve seen two total solar eclipses and have been duly impressed by what happens as the moon casts its shadow on Earth. But recently I’ve become even more intrigued by a similar phenomenon that doesn’t involve the sun or the moon—something called an asteroid occultation. That’s what happens when an asteroid orbits around the solar system and blocks the light of a distant star you’re viewing from Earth. Like the moon during a solar eclipse, the asteroid casts a predictable moving shadow on a swath of Earth’s surface—a small silhouette in the dim light bathing us from that one star. When such a…

Engineering the Substation Exit for Reliability, Capacity, and Expansion

This white paper gives distribution engineers and utility teams a practical overview of the substation exit, the short and high-consequence section where station capacity divides into individual feeders. It explains how covered, spacer-supported overhead construction can reduce common contact-driven faults while leaving room for future circuits. What you will learn about: Why a fault near the substation exposes more customers than one farther along the feeder, and why the first spans out of the station carry so much reliability weight. How covered conductors and spacer-cable systems differ…

Investigating brain stimulation as an alternative to medication in the treatment of epilepsy

Many treatments for drug-resistant epilepsy require surgical procedures that carry risks and do not guarantee success. Therefore, there is a growing need for less burdensome therapies that can be used at home. Steven Beumer explored this challenge as part of his Ph.D. research, which was conducted within the PerStim (Personalized NeuroStimulation) project.

Scientists gave worms magnetic bacteria. They lived 43% longer

Scientists discover an “impossible” cellular survival pathway that could help fight cancer

Scientists discovered a surprising backup system that lets mammalian cells make the essential amino acid cysteine even when the pathways once considered indispensable are disabled. The same survival mechanism may help cancer cells resist treatment, raising the possibility that shutting it down could make tumors easier to kill.

Scientists thought they knew how this 70-year-old leukemia drug worked

A 70-year-old leukemia drug is still revealing new secrets. Researchers found that removing a protein called NUDT5 protected cells from the drug, even though simply blocking the protein had little effect. The unexpected result points to a hidden cellular role that could help explain why people respond differently to certain leukemia treatments.
