Zebra finches alter song to eggs during hot periods to repress heat production in embryo cells

[PhysOrg]

A team of researchers from Deakin University in Australia and Clemson University in the U.S. has found that female finches change the song they sing to their eggs when temperatures rise. This results in hatchling mitochondria producing more ATP and less heat. In their paper published in Proceedings of the Royal Society B, the group describes experiments they conducted with captive zebra finches.
