"From the Ted Talk by Karen Lloyd: This deep-sea mystery is changing our understanding of life"

#### Unscramble the Blue Letters

So by combining measurements from many different places around the world, my ceaguoells at the University of Southern California, Doug LaRowe and Jan Amend, were able to ctllcaaue that each one of these deep-sea moarcibil clles requires only one ztteapwot of peowr, and before you get your pnohes out, a zepto is 10 to the minus 21, because I know I would want to look that up. Humans, on the other hand, require about 100 watts of power. So 100 watts is basically if you take a pineapple and drop it from about waist hghiet to the ground 881,632 times a day. If you did that and then linked it up to a trinbue, that would create enough power to make me hapepn for a day. A zeptowatt, if you put it in similar terms, is if you take just one grain of salt and then you imagine a tiny, tiny, little ball that is one thousandth of the mass of that one grain of salt and then you drop it one nanometer, which is a hundred times smaller than the wavelength of visible light, once per day. That's all it takes to make these microbes live. That's less energy than we ever thought would be capable of supporting life, but somehow, amazingly, buitlfaluey, it's enough.

So by combining measurements from many different places around the world, my __________ at the University of Southern California, Doug LaRowe and Jan Amend, were able to _________ that each one of these deep-sea _________ _____ requires only one _________ of _____, and before you get your ______ out, a zepto is 10 to the minus 21, because I know I would want to look that up. Humans, on the other hand, require about 100 watts of power. So 100 watts is basically if you take a pineapple and drop it from about waist ______ to the ground 881,632 times a day. If you did that and then linked it up to a _______, that would create enough power to make me ______ for a day. A zeptowatt, if you put it in similar terms, is if you take just one grain of salt and then you imagine a tiny, tiny, little ball that is one thousandth of the mass of that one grain of salt and then you drop it one nanometer, which is a hundred times smaller than the wavelength of visible light, once per day.

#### Original Text

So by combining measurements from many different places around the world, my colleagues at the University of Southern California, Doug LaRowe and Jan Amend, were able to calculate that each one of these deep-sea microbial cells requires only one zeptowatt of power, and before you get your phones out, a zepto is 10 to the minus 21, because I know I would want to look that up. Humans, on the other hand, require about 100 watts of power. So 100 watts is basically if you take a pineapple and drop it from about waist height to the ground 881,632 times a day. If you did that and then linked it up to a turbine, that would create enough power to make me happen for a day. A zeptowatt, if you put it in similar terms, is if you take just one grain of salt and then you imagine a tiny, tiny, little ball that is one thousandth of the mass of that one grain of salt and then you drop it one nanometer, which is a hundred times smaller than the wavelength of visible light, once per day. That's all it takes to make these microbes live. That's less energy than we ever thought would be capable of supporting life, but somehow, amazingly, beautifully, it's enough.
