The findings offer a new clue to a phenomenon geochemists have documented for years: heavy metal concentrations in streams and rivers tend to spike after nearby wildfires.

Democritus believed that light refracting through atoms caused the phenomenon that we perceive and describe conventionally, or by mutual agreement, as color.

"We were able to isolate the synaptic mechanisms that drove this and also show that this same phenomenon can be manipulated or blocked by using systemically available drugs."

The material, based on a framework of ruthenium, fulfils the requirements of the 'Kitaev quantum spin liquid state' -- an elusive phenomenon that scientists have been trying to understand for decades.

To dig deeper, the scientists focused on a species with naturally occurring red or yellow forms, a phenomenon that is extremely rare in nature.
