Researchers have identified indole metabolites from the human blood bacterium Paracoccus sanguinis that showed anti-aging activity in laboratory-grown human skin cells. The compounds reduced oxidative stress, inflammation and collagen-degrading activity in cell experiments, according to findings published in the Journal of Natural Products.
New findings challenge the traditional view of five senses, proposing that humans could have between 22 and 33 distinct ones. These senses blend to create our perception of the world, influencing everything from taste to balance. Experts at the University of London highlight how everyday experiences reveal this complexity.

A systematic review led by Edith Cowan University has found that increasing muscle temperature through warm-up routines can significantly enhance performance in rapid, high‑power movements. The study estimates that for every 1°C rise in muscle temperature, speed- and power-related performance improves by around 3.5%, while maximum strength remains largely unchanged.
