First solid evidence that the study of music promotes intellectual development

A study published in Psychological Science found that extra-curricular music lessons significantly improved IQ scores and academic performance in six-year-old children. The research, led by Dr. E. Glenn Schellenberg, showed that music lessons had a more pronounced effect on cognitive development than drama lessons or no lessons at all.

Study of obscure Amazon tribe sheds new light on how language affects perception

Researchers found that adult members of the Pirahã tribe performed accurately with small sets of objects but struggled with larger numbers, indicating that their language lacks precise numerical representation. The study suggests that having the right linguistic resources can carve out one's reality and influence perception.

Scientists reinvent DNA as template to produce organic molecules

Researchers at Harvard University have developed a technique to produce organic molecules by attaching them to single DNA strands, which can then be used as a sequence-programmable assembly line for chemical synthesis. This method enables the selection and amplification of molecules with desired functional properties.

Muscles are smarter than you think

Researchers discovered that muscles use acidosis to maintain proper nerve signal response, avoiding fatigue. By peeling away the muscle fiber's surface membrane, the team studied the effects of acidity on force response, finding it counteracts fatigue at a critical step in excitation-contraction-coupling.
