A Quote by James Rothman
I became aware of the very complex internal organization in a cell from the basic science classes, and it made me think about how all that could work. It seemed like a great mystery, especially how organelles in the cell can be arranged in three dimensions, and how thousands of proteins could find their way to the right location in the cells.

In science there is something known as a stem cell. A stem cell is an undifferentiated cell which has not yet decided whether it's gonna be a cell of your brain or a cell of your heart or of your finger nail. But science is learning how to coax, how to manipulate, the raw material of life that we call stem cell to become any cell of the body. I think that God is the stem cell of the universe.
Although a biologist, I must confess I do not understand how life came about... I consider that life only starts at the level of a functional cell. The most primitive cells may require at least several hundred different specific biological macro-molecules. How such already quite complex structures may have come together, remains a mystery to me. The possibility of the existence of a Creator, of God, represents to me a satisfactory solution to this problem.
The need for a quick, satisfactory copying machine that could be used right in the office seemed very apparent to me-there seemed such a crying need for it-such a desirable thing if it could be obtained. So I set out to think of how one could be made.
It is easy to make out three areas where scientists will be concentrating their efforts in the coming decades. One is in physics, where leading theorists are striving, with the help of experimentalists, to devise a single mathematical theory that embraces all the basic phenomena of matter and energy. The other two are in biology. Biologists-and the rest of us too-would like to know how the brain works and how a single cell, the fertilized egg cell, develops into an entire organism
There are thousands of proteins in the cells, some of them very large chains of molecules. And the cell doesn't function if one of those chains of molecules isn't there, and you start looking at the complexity of life and the mystery of life, and then start thinking about things like the twenty universal constants, that if any one of them from Plank's minimum to the mass of a proton, if one of them is the tiniest bit off, there would be no life or possibility of it in the universe.
Inside of a living cell there are thousands of proteins that enable it to make more of itself and make your malaria drug, for instance. We don't understand those. We don't understand how they work together.
The number of cells in our bodies is defined by an equilibrium of opposing forces: mitosis adds cells, while programmed cell death removes them. Just as too much cell division can lead to a pathological increase in cell number, so can too little cell death.
Every time I see a film or TV show, I think about how that composer made those choices and how that director envisioned music and how that could work onstage or in a film and how you could support that even further by putting lyrics to it.
It's actually very surprising how little we think about the quality of our decision-making and how we could improve it. How absent decision-making classes are from educational curricula. How little we think about how it is we think.
If we could take one of my skin cells and turn it into an embryo-like cell and turn it back into a skin cell, it has reset almost all of the developmental indications of age.
We're all one thing, like cells in a body. 'Cept we can't see the body. The way fish can't see the ocean. And so we envy each other. Hurt each other. Hate each other. How silly is that? A heart cell hating a lung cell.
A stem cell is essentially a blank cell capable of becoming another, more differentiated cell-type in the body, such as a skin cell, a muscle cell or a nerve cell.
Every cell in your body is totally aware of how you think and feel about yourself.
The way I work is I like to immerse myself in the world of the film and in the character's lives, and then from that, I get a lot of ideas of how the film could be made, how it could be told.
Hello, cell. How are you? Still dank and dirty? Me? I've taken up a new habit: talking to my cell. It's like talking to myself but slightly more pathetic.
Biology is a science of three dimensions. The first is the study of each species across all levels of biological organization, molecule to cell to organism to population to ecosystem. The second dimension is the diversity of all species in the biosphere. The third dimension is the history of each species in turn, comprising both its genetic evolution and the environmental change that drove the evolution. Biology, by growing in all three dimensions, is progressing toward unification and will continue to do so.
