I don't understand this but it might be of interest to more knowledgeable people.
QuoteNanoscale circuits based on molecules used in sunscreen lotion have led to the discovery of the "missing link" of electronics engineering – a previously mythical device known as a "memristor".
First predicted in 1971, the memristor could help develop denser memory chips or even electronic circuits that mimic the synapses of the human brain, says Stan Williams who made the discovery with colleagues at Hewlett-Packard's lab in Palo Alto, California................

Intriguing, as far as I understand it, and with great potential for us all. Great link, Noreen. :thumb:
