They held workshops and visited homes to get everyone's input. Afterward, they surveyed people to see who took
Scientists have come up with a clever way to detect tiny amounts of carbamate pesticides. They used a mix of natural ingredients to create special beads. These beads can soak up and concentrate the pesticides. This makes it easier to spot them in food and the environment. The process is called micro
In the heart of Southwest China, Panzhihua stands as a testament to large-scale mining and smelting. These activities have left an indelible mark on the city's atmosphere, with dust serving as a major carrier of heavy metals. Identifying the sources of these metals is a complex task, as various poll
Neopterin, or NPT, is a crucial signal in the body's immune response. It plays a big role in spotting and keeping an eye on various health issues. Scientists have come up with a new way to measure NPT in human blood and a lab-made fluid that mimics what's in our spinal cord. They used a special mate
The idea that large language models (LLMs) can stand in for humans in research is gaining traction. These models can produce responses that seem human-like, performing well in economic tests, surveys, and political discussions. This has sparked interest in using LLMs to simulate human behavior in so
Cancer can lurk in the body for years, often without any noticeable symptoms. This makes it difficult to catch early, when treatment is most effective. But recent studies have shown that blood tests might change the game. Scientists have been looking into ways to spot cancer before it shows any sign
