We can do genetics. We can do experiments on fruit flies. We can do experiments on yeast. It's not so easy to do experiments on humans. So, in fact, it helps us, to interpret our own genetic code, to have the genetic code of the other species.
Well, we can study aging in people, but of course those studies take decades. So what we try to do is we use simpler organisms to try and understand the basic mechanisms and so in my laboratory, for example, we use things like simple baker's yeast that we use to make bread.
It's been known since 1916 that cutting back calories is beneficial in every organism it's been tested on - from yeast to worms to mice to monkeys. I think it would be a surprise if we are an exception to that rule.
A bad act done will fester and create in its own way. It's not only goodness that creates. Bad things create. They have their own yeast.
Microbes such as bacteria and yeast use enzymes to make fuels from biomass. We use directed evolution to perfect those enzymes and make new fuels efficiently.
Coproporphyrin in particular is widespread; traces are present in normal urine and also in yeast. In special cultures, yeast can be made to produce considerable quantities of coproporphyrin.
Enthusiasm is the yeast that makes your hopes shine to the stars. Enthusiasm is the sparkle in your eyes, the swing in your gait. The grip of your hand, the irresistible surge of will and energy to execute your ideas.
You can't just leave out one part; the bread won't rise if the yeast isn't there.
Jellyfish serve as a model for bioengineers for the same reason yeast were once so valuable to geneticists: they're simple to deconstruct.
I only take vitamin B complex. Before World War II, I used to take ionized yeast, because in the pre-war era we never heard about vitamins.
