Scientists found DNA-like molecule that assemble itself

Chemists say they have found a way to make a DNA-like molecule assemble itself in a pond-like setting—potentially suggesting a key step in how life originated. The researchers actually worked with a simpler molecule, called pre-RNA. It’s hypothesized to have eventually evolved into DNA—one stopping point along the way having been the creation of a third substance, RNA, still used in the body to translate the code inscribed in DNA.

Study : Matching brain rhythms are used to process music

Scientists say they have found how brain rhythms are used to process music, a finding that shows how our perception of notes and melodies can be used to better understand the hearing system. The study, which appears in the journal Proceedings of the National Academy of Sciences this week, points to a new role for “cortical oscillations,” or rhythmic repetitions of nerve cell activity in the brain.
