flag Sleep boosts puzzle-solving, babies predict rhythms, and some reptiles lack hunger gene, study finds.

flag A new study finds that sleeping on a difficult puzzle can improve problem-solving, as sleep helps the brain reorganize and process information, leading to insights upon waking. flag Researchers also discovered that newborns can predict complex musical rhythms, likely due to innate sensitivity to biological rhythms like heartbeats, but do not show the same ability to anticipate melodies. flag Meanwhile, scientists found that some snakes and chameleons have lost the gene for ghrelin, a hunger-signaling hormone in humans, which may explain their ability to survive months without eating. flag The findings, published in the Royal Society journal, highlight how biological rhythms and genetic adaptations influence cognition and survival.
