Metallic materials used in extremely cold environments must maintain high strength, ductility and fracture toughness to support applications in aerospace, clean energy, superconducting systems and deep-space exploration. However, traditional alloys often suffer performance degradation at ultralow temperatures because of the long-standing trade-off between strength, ductility and toughness. Although metals may become stronger at lower temperatures, they can also become more brittle and prone to fracture.

Newly identified protein pathway helps HIV stay hidden despite treatment

Current HIV medicines are effective at suppressing the virus in the blood. However, HIV can remain "asleep" or dormant inside certain immune cells and in the brain. These hidden pockets of virus, called HIV reservoirs, are the main reason HIV cannot be cured with today's treatmen

Scientists discover ghostly, eyeless creature hidden in Chinese cave

Deep inside a high-altitude Chinese cave, scientists discovered a ghostly, eyeless freshwater snail that has evolved to live entirely in darkness, marking the first recorded discovery of its kind in China. Named after a faceless mythical creature, the rare species may already be
