So in other words, as long as our cells are wearing a thick coat of sialic acid, they look fabulous, right?
So in closing, let me just remind you again: your cells are coated with sugars.
The sugars are telling cells around that cell whether the cell is good or bad.
And that's important, because our immune system needs to leave the good cells alone.
And now that we understand how those sugars mesmerize the immune system, we can come up with new medicines to wake up those immune cells, tell them, "Ignore the sugars, eat the cell and have a delicious snack, on cancer."
Second, we're going to need to scan individual human brains in fine spatial and chemical detail, to see exactly what cells are where, connected to what, of what type.
If we have good enough models of all the kinds of brain cells and a good enough model of the brain, we can put it together to make a good enough model of an entire brain, and that model would have the same input-output behavior as the original.
Now, for me, this little pond scum critter Tetrahymena was a great way to study the fundamental mystery I was most curious about: those bundles of DNA in our cells called chromosomes.
It was important when cells divide.
Four becomes eight, and on and on to form the 200 million billion cells that make up our adult body.
And some of those cells have to divide thousands of times.
In fact, even as I stand here before you, all throughout my body, cells are furiously replenishing to, well, keep me standing here before you.
So every time a cell divides, all of its DNA has to be copied, all of the coding DNA inside of those chromosomes, because that carries the vital operating instructions that keep our cells in good working order, so my heart cells can keep a steady beat, which I assure you they're not doing right now, and my immune cells can fight off bacteria and viruses, and our brain cells can save the memory of our first kiss and keep on learning throughout life.
And those keep the shoelace, or the chromosome, from fraying, and when that tip gets too short, it falls off, and that worn down telomere sends a signal to the cells.
The craziest thing was, Tetrahymena cells never got old and died.
My skin cells start to die and I start to see fine lines, wrinkles.
Hair pigment cells die.
Immune system cells die.
Somehow they were able to experience their circumstances not as a threat day in and day out but as a challenge, and this has led to a very important insight for all of us: we have control over the way we age all the way down into our cells.
We can program rules for pattern formation, how cells in a tissue determine what role they're going to take on and set the patterns of our bodies.
(Machine buzzes) Now, in the real-world gene therapy and gene therapy research, healthy genes are being administered to unhealthy cells using viruses.
DNA is the long, string-like molecule that winds up inside our cells.
You can think of it like this: inside our cells, there's different contraptions building things, connecting circuits, doing all the things they need to make life happen.
One of the stunning things about our cells is that the components inside them are actually biodegradable.
A big difference between our cells and the traveling carnival is that in the carnival, there are skilled craftsmen that rebuild the rides each day.
In our cells, there are no such skilled craftsmen, only dumb builder machines that build whatever's written in the plans, no matter what those plans say.
The instructions for every nook and cranny inside our cells.
If everything in, say, our brain cells dissolves almost every day, then how can the brain remember anything past one day?
What it has is water inside the cells and when the voltage hits it, it opens up, releases the water, changes the shape of the cells, and the leaf falls.
In your lab there are 36 habitat cells, arranged in an inverted pyramid, with 8 cells in the top row.
