Super-sleepers could help super-sizers!
Many species of animals go through a period of torpor to conserve energy when resources are scarce. But when it comes to switching to energy-saving mode, the champion by far among vertebrates is the burrowing frog (Cyclorana alboguttata), which can survive for several years buried in the mud in the absence of any food or water. How do they accomplish this feat? A team of scientists at the University of Queensland have discovered that the metabolism of their cells changes radically during the dormancy period allowing the frogs to maximise the use of their limited energy resources without ever running on empty. This discovery could prove to have important medical applications in the long term. "It could potentially be useful in the treatment of energy-related disorders such as obesity", explains Ms. Sara Kayes who will present her findings at the Society of Experimental Biology Annual Meeting in Glasgow on Monday...
