TOKYO (AFP) - Japanese researchers have succeeded in producing see-through frogs, letting them observe organs, blood vessels and eggs under the skin without performing dissections.
"You can see through the skin how organs grow, how cancer starts and develops," said the lead researcher Masayuki Sumida, professor at the Institute for Amphibian Biology of state-run Hiroshima University.
"You can watch organs of the same frog over its entire life as you don't have to dissect it. The researcher can also observe how toxins affect bones, livers and other organs at lower costs," he told AFP.
Dissections have become increasingly controversial in much of the world, particularly in schools where animal rights activists have pressed for humane alternatives such as using computer simulations.
