A new study reveals that the brain clock itself is driven, in part, by metabolism.

The New England Banksia is largely restricted to the eastern edge of the New England Tableland, and is common in places along Waterfall Way. Researchers have raised this flowering plant, until now classified as a variety of the Hairpin, to the taxonomic level of a distinct species.
