"Japanese To Patent Transparent Frog":

So reports The Register (U.K.). "The scientists reckon this will make biological research -- not to mention school biology lessons -- signifcantly less messy and traumatic, as it will no longer be necessary to cut the slime-filled creatures up in order to examine their innards."

By the way, while some frogs' skin might feel slimier than ours, aren't we all "slime-filled"?

Thanks to Michael Barclay for the pointer.
