This podcast is brought to you by the American Chemical Society. The global challenges chemistry solutions podcast from ACS discusses how chemistry researchers critical in solving some of the world's most daunting problems, concerning energy, food and water. Go to ACS.org for more information.
This is Scientific American's 60-Second Science. I'm Karen Hopkin. This will just take a minute.
Truth in advertising is a questionable concept, because it’s often self-serving to lie. Whether you’re talking about a used car salesman or a poisonous snake. No, they’re not the same thing.
In the natural world there are poisonous creatures that advertise their unpalatability with bright colors. Then there are other critters that try to protect themselves by merely mimicking the bright coloration of creatures that produce nasty toxins—but without actually expending the energy on making the toxins themselves. These mimics are hoping to get by by lying about being a bad meal. But what about the beasties that really are filled with poison. Can they lie, too? Maybe save a little energy by producing a less colorful display?
Well, scientists from the

Well, scientists in theUK say, it
looks like they can’t. See, when an animal makes a toxin, it also makes an antitoxin
to keep it from poisoning itself. And those antitoxins are usually antioxidants,
which also double as pigments. So the more toxic a critter is, the more antioxidants
it needs, and the more honestly flamboyant its outfit—results published by the
Royal Society on November 19th. So next time you run into a
yellow-banded and poison dart frog, remember, what you see is what you get.

Go to ACS.ORG for more information. This is the scietific Americans sixty seconds science. I am Karen Hopkin. This will just take a minute. Truth in advertising is a quesionable concept becouse it ofen self-serving to lie.Whether you will talking about used car sales, minoral poisonous snakes, no there are not the same thing. In the natral world there poisonous creatures that advertising their unparalled ability with bright colors. Then the other criters try to protect themselves by merely mimicing the bright color --the creatures that produce nasty toxins, but we now actrually spending energy and making the toxins themselves. This mimics are hoping to get by by lying being a bad meal. But what about beasties really are felt was poison can they lie to? May be save a little energy by producing a less colorful display? While saying from the UK say, it looks like the kent, see an animal makes a toxin, it also makes an antitoxin to keep it from poison itself. Those antitoxins are usually antioxidents which also double its pigments. So more toxincal creature is more antioxidents it needs and more honestly flatboy it is outfit.
