Mondiali: la corsa verso la finale, al via i quarti – Mondiali 2026 – Ansa.it

Rimaste in otto, il Mondiale 2026 entra nella sua fase decisiva. Francia, Spagna, Inghilterra e Argentina erano tra le principali favorite della vigilia e hanno rispettato i pronostici, ma il cammino verso la semifinale passa ora attraverso quattro sfide che promettono spettacolo. A contendere loro un posto tra le migliori…

These ancient quasars shouldn't exist so soon after the Big Bang

Quasars rank among the brightest and most powerful objects in the universe. They are fueled by supermassive black holes that consume surrounding material at the centers of galaxies, producing so much energy that they can be seen across billions of light years. Now, an international team of researchers has identified…

This Mars rover could finally reveal whether life ever existed on Mars

Mars was not always the cold, dry world we see today. Billions of years ago, scientists believe it may have been warm, wet, and wrapped in a much thicker atmosphere, creating conditions that could have supported simple microbial life. Even so, proving that life ever existed there remains one of…

Arrivano Sol, Terra e Luna. I nuovi modelli IA di OpenAI – Notizie – Ansa.it

OpenAI, l’azienda madre di ChatGpt, renderà disponibile giovedì l’ultima serie di modelli di intelligenza artificiale, in una mossa che sembra avere l’approvazione del governo statunitense per un lancio su più ampia scala. La nuova proposta dell’azienda, GPT-5.6 Sol, insieme ad altri modelli di IA all’avanguardia — tra cui la serie…

Scientists finally solved a 150-year-old gallium mystery

Nearly 150 years after gallium was first discovered and added to the periodic table, scientists at the University of Auckland have uncovered previously unknown details about the metal’s atomic structure and behavior. Gallium was discovered in 1875 by French chemist Paul Émile Lecoq de Boisbaudran. It is best known for…

Trees keep absorbing carbon long after they stop growing

Trees do not necessarily keep growing for as long as they keep photosynthesizing, according to a new study published in Science Advances. Researchers found that oak trees continue absorbing carbon dioxide well after their annual growth has ended, suggesting forests may store less carbon in wood than many climate models…

A vitamin A discovery is changing what scientists know about vision

Scientists at Johns Hopkins University have uncovered how humans develop sharp central vision before birth, identifying a carefully timed interaction between a vitamin A derived molecule and thyroid hormones in the retina. The discovery challenges a decades old explanation for how key light sensing cells form and could guide future…

The Ozempic and Wegovy mistake sending thousands to poison control

The explosive growth in semaglutide (Ozempic and Wegovy) We use after its FDA approval for chronic weight management in 2021 was accompanied by another trend that drew researchers’ attention: a dramatic increase in calls to poison control centers across the United States. Jordan Miller, then an undergraduate student at UT…

Harvard scientists turn a silicon chip into a DNA writing machine

Silicon chips have been the foundation of modern computing for decades. Now, researchers are giving them an entirely new role in biotechnology. In addition to processing information, these chips are increasingly being used to study living systems by recording activity from neurons, reading DNA, and now even creating DNA. In…

Nel 2026 il giugno più caldo per l’Europa occidentale – Notizie – Ansa.it

Giugno 2026 è stato il giugno più caldo mai registrato per l’Europa occidentale e il secondo più caldo a livello globale. Ha registrato temperature quasi record, trainate da quelle superficiali del mare mai così alte per il mese. Lo afferma il programma di osservazione della Terra dell’Unione Europea, Copernicus Climate…

Tiny silica particles wiped out aggressive prostate cancer in mice

Researchers have developed tiny silica nanoparticles that can directly destroy prostate tumors while also awakening the body’s immune system to fight cancer, according to a new preclinical study led by scientists at Weill Cornell Medicine and the Cornell Duffield College of Engineering. In mouse models of aggressive prostate cancer, the…

Heidelberg physicists just united two opposing quantum theories

A new theory developed by physicists at Heidelberg University brings together two long competing ideas in quantum physics, offering a unified explanation for how an unusual particle behaves inside a crowded quantum environment. The work connects two seemingly opposite descriptions of a single impurity moving through or remaining nearly motionless…
