Gold nanoparticles unlock vibrant structural colors across the visible spectrum

A common explanation for why waste management sometimes fails is that carelessness breeds more carelessness. Now, research from the University of Gothenburg shows that dirty waste disposal rooms can evoke feelings of disgust that increase the risk of people disposing of their waste incorrectly.

Incorporating more plant-based proteins could help people save on their grocery bill, but new research has found that it's not so simple when it comes to choices at the supermarket. Simon Fraser University researchers peeked into more than 87,000 grocery carts in Canada and Finland to study how much price influenced the type of protein people bought: animal-based or plant-based. Researchers discovered that while the price had to be right, having a variety of options also played a role.

Biophotonics is a multidisciplinary field that involves the development and application of light-based technologies to study, monitor and treat biological systems. The ability to directly image cells and molecules has led to many fundamental discoveries in the past century. More recently, the terahertz (THz) region of the electromagnetic spectrum has attracted growing interest as a promising frontier for advancing biological research.

For millions of people, chatbots powered by large language models (LLMs) are now a key feature of everyday life. These AI systems are growing at a rapid pace, but scaling them up is becoming increasingly costly and resource-intensive.
