In chapter 8, we talk about the frequencies used by different regions of the brain to communicate with each other in processing sound and music. In particular we noted "two particular frequency regions, the theatre (4-8 Hz) and the alpha (8-13 Hz) were found to activate" (173) in music processing. But what about the noise that neuroscientists have to sift through to discern these frequencies? Increasingly in new studies, neuroscientists are discovering fluctuations in the noise that are meaningful and found throughout nature, even in pieces of music: https://www.quantamagazine.org/brains-background-noise-may-hold-clues-to-persistent-mysteries-20210208/ (a number of academic sources are cited in the article detailing current study of this subject).

A fascinating new article in Science News that posits that "A magnetic field reversal 42,000 years ago may have contributed to mass extinctions." The article also suggests that the sudden appearance of red ochre handprints in caves may have come about due to ochre being used as a protective sun screen to shield against large-scale changes in weather patterns and ultraviolet radiation causes by a reversal of the earth's magnetic poles.
