A TINY peptide called nociceptin may play a key role in feeling pain. Makoto Inoue and his colleagues at Osaka University applied the peptide to the foot pads of lightly anaesthetised mice. They found that nociceptin was 10 000 times better at inducing muscle twitches that indicate pain sensation than another pain signalling molecule, “SP”. They then showed that nociceptin works by causing cells to release SP (Proceedings of the National Academy of Sciences, vol 95,
