Alice Roberts: 'We are fundamentally, at the end of the day, animals'

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.

Colloidal photonic glasses offer an appealing way to produce vivid colors without any chemical dyes—but so far, a stubborn optical effect has long prevented them from generating a true red color. Now, Yuwon Jeon and colleagues at KU-KIST in Seoul have developed a new approach that overcomes this limitation, producing bright, stable colors spanning the full visible spectrum. The research has been published in Proceedings of the National Academy of Sciences.

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.
