Why do animals sleep? This is a question with many potential answers. It is known that birds and mammals experience slow-wave and rapid eye movement (REM) sleep patterns. During the first pattern, slow waves with high amplitudes can be seen if measuring electrical activity (EEG) in the cortex.…

He's certainly not the only person to have discovered a flash insight after waking from a good sleep. In science alone, many breakthroughs were apparently borne of a decent snooze, including Mendeleyev's creation of the Periodic Table and Loewi's experiments on the transmission of nervous signals through chemical messengers.
Most of us have tried sleeping on a difficult problem before and using…
