Optical fibers are already the backbone of global communication systems. Recently, however, physicists have started to explore how their functionality could be boosted further by conveying information via entangled quantum ...

A new study published in Science Advances takes a closer look at how AI agents' choices are influenced by their peers. The team found that more advanced models tend to follow the majority when shown other agents' choices, ...

Volcanoes emit smoke. Beneath a volcano lies a huge chamber filled with liquid magma. A series of earthquakes means an eruption is imminent. And if a "supervolcano" like Yellowstone were to awaken, a global catastrophe would ...

A team of researchers reports that they may have found rock containing some of the earliest forms of microbial life on Earth. Their study, published in the Proceedings of the National Academy of Sciences, describes the biosignatures ...

States are moving faster and further than federal regulators to get kratom off store shelves, with some banning the herb outright while a pending federal rule targets only one of its chemicals.

As we age, the skin loses part of its ability to regenerate, heal wounds and maintain an effective barrier against the outside world. Among the causes of this deterioration is low-grade, persistent age-associated inflammation, ...

Upadacitinib is a medication widely used for the treatment of rheumatoid arthritis that works by inhibiting Janus kinase (JAK) enzymes, which are involved in signaling pathways that regulate immune responses. Now, scientists ...

Today, most of us interact with AI assistants—reactive bots that wait for human instructions. Yet AI assistants are rapidly being replaced by agentic AI agents that can interact with external tools, browse the web, generate ...

So far, most of the minerals found on Mars tell a story of lava poured out by ancient volcanoes, followed by long stretches in which water trickled through and slowly reshaped the rock. However, some rocks scattered across ...

Between 29,000 and 19,000 years ago, the planet experienced some of its coldest temperatures and drastic landscape changes at the peak of the Ice Age, during the Last Glacial Maximum (LGM), the period of most extensive global ...

Quantum sensors, devices that collect measurements by exploiting quantum-mechanical phenomena, could potentially detect extremely weak magnetic, gravitational and electromagnetic signals with greater sensitivity than classical ...

Recent advances in our understanding of human evolution challenge the way we currently name and classify our ancestors, according to new research from Monash University. The study, published in the American Journal of Biological ...
