A team of researchers at IOCB Prague headed by Dr. Tomáš Slanina has developed a new method for labeling molecules with fluorescent dyes that surpasses existing approaches in both precision and stability. The new fluorescent label remains covalently bonded to its target molecule and does not fall apart even under demanding conditions inside living cells. This allows scientists to track labeled molecules over long periods with high reliability – an advantage for research in biology, chemistry, and medicine. The study was published in Angewandte Chemie International Edition.

Excessive screen use among school-aged children has been linked to sleep disturbances and behavioral problems, but its effects on brain development have remained unclear. Now, researchers from Japan have examined data from over 11,000 children to explore the relationship between screen time, attention-deficit/hyperactivity disorder (ADHD) symptoms, and brain structure. Their findings reveal that longer daily screen exposure is linked to increased ADHD symptoms and measurable changes in brain development.
