A surprising new discovery suggests that fear may cause the brain to blur the line between danger and safety rather than distinguish them more clearly. By observing brain activity in mice using augmented reality, scientists found that memories of threatening and harmless environments began to overlap, potentially allowing faster responses to danger. This "better safe than sorry" survival mechanism could help…

Scientists identify two overlooked skills that predict reading success
A massive new study reveals that intelligence plays a surprisingly limited role in children's reading success, while visual processing showed no meaningful connection at all. Instead, the strongest predictors are sound recognition, vocabulary, and background knowledge, offering new clues about how to help struggling readers.
