American Bradley fighting vehicles were visible on the horizon as they raced towards the city. Smoke, deployed to conceal movement, curled around the outskirts. The assault forces, preparing to assault the enemy fortress, gathered at the northern end, avoiding barbed wire, cars and concrete blocks: enemy obstacles intended to slow the assault. The urban assault, … Read more
Deep in the Black Hills of South Dakota, USA, in a former gold mine, a tank of liquid xenon has been used to produce an unusual particle reaction that may be a link to “dark matter”. Scientists conducting an experiment there say they have found a single “unexplained particle interaction” that resembles a dark matter … Read more
Astronomers have used the MeerKAT radio telescope to detect hydrogen gas billions of light years away from us, from a period when the cosmos was billions of years younger than its current age of 13.8 billion years. The research may provide astronomers with a new way to map the large-scale structure of the universe. The … Read more
Miracinonyx trumani, an extinct big cat commonly known as the American cheetah, lived in North America during the Pleistocene. Its nickname comes from its resemblance to modern cheetahs, including physical traits suitable for high-speed pursuit. But scientists’ understanding of this ancient predator has changed in recent years and now researchers have discovered surprising new details … Read more
Scientists are closer than ever to understanding how stars forge the elements that make up our planet, our bodies, and virtually everything around us, and they’re getting a clearer picture of where stellar explosions fit into the story. New research published in two different papers looks at how stars forge elements as they explode, and … Read more
When Lilah Mehta entered a biomedical research laboratory at Yale University when she was 16, her main goal was to explore the biological questions that had interested her since her ninth-grade science classes. Two years later, the New Canaan resident and student at the King School in Stamford reached an academic milestone rarely achieved before … Read more
La brillante capa de nubes de Venus ha sido descrita durante casi medio siglo como gotas concentradas de ácido sulfúrico suspendidas en una atmósfera de dióxido de carbono. Un artículo de 2025 se pregunta si un experimento accidental durante el descenso de una sonda en 1978 registró algo mucho más complicado químicamente. El reanálisis revisado … Read more

When we imagine a glacier, we tend to imagine a huge chunk of ice spread over a mountain valley or descending from a snow-covered peak. But not all glaciers look as expected. Some are hidden beneath a jumble of rocks, with the ice buried out of sight. These formations, known as rock glaciers, can hide … Read more
CAPE CANAVERAL, Fla. (AP) — A private spacecraft that was supposed to provide a lifeline to NASA’s Swift Observatory managed to get close to the sinking telescope and even took photographs more than a week after the rescue was abandoned. But the three-armed robotic rescuer had to move away due to low fuel, according to … Read more
