2011-12-21 04:54:27

Researchers of the Max Delbrück Center for Molecular Medicine (MDC) Berlin-Buch have found out why the African naked mole-rat (Heterocephalus glaber), one of the world´s most unusual mammals, feels no pain when exposed to acid. African naked mole-rats live densely packed in narrow dark burrows where ambient carbon dioxide (CO2) levels are very high. In body tissues, CO2 is converted into acid, which continuously activates pain sensors. However, naked mole-rats are an...

Naked mole rats (Heterocephalus glaber) live in a 'hive' society with one reproducing queen and between one and three reproducing males. The rest of the mole rats in the colony are workers either defending the burrow or finding food — not an easy task when you are virtually blind and all the tunnels smell of mole rat. New research published in BioMed Central's open access journal BMC Evolutionary Biology shows that mole rat sperm has become simple and degenerate, probably due to...
