From the Ted Talk by Cynthia Kenyon: Experiments that hint of longer lives

Unscramble the Blue Letters

If you look at birds, which live a long time, clles from the birds tend to be more resistant to a lot of different environmental stresses like high temperature or hdyoregn peroxide, things like that. And our long-lived mutants are too. They're more resistant to these kdins of steresss. So it could be that the pathways that I've been talking about, which are set to run really quickly in the worm, have a different normal set ponit in something like a bird, so that a bird can live a lot longer. And maybe they're even set really difenefrtly in animals with no senescence at all — but we don't know.

If you look at birds, which live a long time, _____ from the birds tend to be more resistant to a lot of different environmental stresses like high temperature or ________ peroxide, things like that. And our long-lived mutants are too. They're more resistant to these _____ of ________. So it could be that the pathways that I've been talking about, which are set to run really quickly in the worm, have a different normal set _____ in something like a bird, so that a bird can live a lot longer. And maybe they're even set really ___________ in animals with no senescence at all — but we don't know.

Original Text

If you look at birds, which live a long time, cells from the birds tend to be more resistant to a lot of different environmental stresses like high temperature or hydrogen peroxide, things like that. And our long-lived mutants are too. They're more resistant to these kinds of stresses. So it could be that the pathways that I've been talking about, which are set to run really quickly in the worm, have a different normal set point in something like a bird, so that a bird can live a lot longer. And maybe they're even set really differently in animals with no senescence at all — but we don't know.
