Thought for the month

“There is nothing noble in being superior to some other man. The true nobility is in being superior to your previous self.” Probably W.L. Sheldon, US lecturer on ethics (1858 – 1907) rather than Ernest Hemingway.

Rubber dub - tweet, tweet

A simple rubber device that replicates complex bird songs has been developed by a team of US researchers.
The song is produced by blowing air through the device, which mimics a bird's vocal tract, the team explained.
The findings appear to challenge the idea that birds had to learn complicated neurological controls in order to produce distinctive calls.
