Ancient Egyptian physicians used a grain-based method to test for pregnancy by exposing barley and emmer wheat to urine samples. If the seeds germinated, pregnancy was considered likely. This early diagnostic practice, recorded in texts such as the Ebers Papyrus, has drawn modern scientific interest due to its possible biological basis.
The ThyRed Base is a newly launched wearable neck-mounted device designed to deliver red and near-infrared light therapy in a hands-free format. Using wavelengths of 630nm, 660nm, and 830nm, it falls within the photobiomodulation category, a field that studies how specific light frequencies interact with biological tissue. The device is designed to provide consistent, localized exposure to the neck area, aiming to support at-home use of low-level light therapy technology in a portable and user-friendly form factor.
Memory is no longer understood as a process confined to the brain alone. Emerging research across neuroscience, biology, and medicine reveals that memory is distributed across neural networks, cells, and even systems like the immune system and gut.
For decades, human language has been seen as a defining feature separating us from other animals. Recent research on Japanese tits, small songbirds of East Asia, challenges this view in surprising ways. Over twenty years of careful observation reveal that these birds combine calls in specific sequences, and that the order of these calls affects how other birds respond.
