It was during this time that I attended a seminar conducted by Dr Bonnie Bassler from Princeton University, where she talked about how bacteria cells communicate with each other, based on their population density, and perform a specific action.
It was at this moment that a light bulb went off in my head, and I thought, "Wow, I see this in my cancer cells every day, when it comes to their movement."
I hypothesized that cancer cells are able to communicate with each other and coordinate their movement, based on how closely packed they are in the tumor microenvironment.
After years of conducting experiments together and merging different ideas and perspectives, we discovered a new signaling pathway that controls how cancer cells communicate with each other and move, based on their cell density.
My work shows that even cancer cells use collaboration to invade our bodies and spread their wrath.
Researchers recently have looked at the question of biopsies, cancerous biopsies, and they've asked the computer to identify by looking at the data and survival rates to determine whether cells are actually cancerous or not, and sure enough, when you throw the data at it, through a machine-learning algorithm, the machine was able to identify the 12 telltale signs that best predict that this biopsy of the breast cancer cells are indeed cancerous.
They said, "We'll be out by Christmas," and Christmas would come and Christmas would go, and then it would be Christmas again, and when they didn't get out, they became disappointed, demoralized and many of them died in their cells.
So almost all the biology that we observe can be thought of as a series of problems and their corresponding solutions, and the first problem that every organ must solve is a continuous supply of nutrients to fuel all those cells of the body.
It takes up proteins and other waste from the spaces between the cells, it collects them, and then dumps them into the blood so they can be disposed of.
Instead, the CSF was pumped back into and through the brain along the outsides of the blood vessels, and as it flushed down into the brain along the outsides of these vessels, it was actually helping to clear away, to clean the waste from the spaces between the brain's cells.
If you think about it, using the outsides of these blood vessels like this is a really clever design solution, because the brain is enclosed in a rigid skull and it's packed full of cells, so there is no extra space inside it for a whole second set of vessels like the lymphatic system.
And what's amazing is that no other organ takes quite this approach to clearing away the waste from between its cells.
Yet in the same animal, if we wait just a little while until it's gone to sleep, what we see is that the CSF is rushing through the brain, and we discovered that at the same time when the brain goes to sleep, the brain cells themselves seem to shrink, opening up spaces in between them, allowing fluid to rush through and allowing waste to be cleared out.
Our own research, now it's 2,000 years later, suggests that what's happening is that when the brain is awake and is at its most busy, it puts off clearing away the waste from the spaces between its cells until later, and then, when it goes to sleep and doesn't have to be as busy, it shifts into a kind of cleaning mode to clear away the waste from the spaces between its cells, the waste that's accumulated throughout the day.
But in patients with Alzheimer's disease, amyloid-beta builds up and aggregates in the spaces between the brain's cells, instead of being cleared away like it's supposed to be, and it's this buildup of amyloid-beta that's thought to be one of the key steps in the development of that terrible disease.
To explain what microRNAs are and their important role in cancer, I need to start with proteins, because when cancer is present in our body, protein modification is observed in all cancerous cells.
And this plant, in fact, is giving the cosmetic chemists very important ingredients that are actually finding ways to slow down the aging process and at the same time reinforce the cells against the onslaught of environmental toxins.
So now, everybody here knows that the body is made up of cells.
But it actually turns out that your cells sit in this mesh of complicated fibers, proteins and sugars known as the extracellular matrix.
So now, the ECM is actually this mesh that holds the cells in place, provides structure for your tissues, but it also gives the cells a home.
So as you see, your cells sit in this complicated mesh and as you move throughout the tissue, the extracellular matrix changes.
In this pathology case, the computer system actually discovered that the cells around the cancer are as important as the cancer cells themselves in making a diagnosis.
It's nothing but using sensors to read the electrical brainstorms that a brain is producing to generate the motor commands that have to be downloaded to the spinal cord, so we projected sensors that can read hundreds and now thousands of these brain cells simultaneously, and extract from these electrical signals the motor planning that the brain is generating to actually make us move into space.
Imagine a world where people with diabetes do not have to rely on insulin after every meal because we can provide them with good pancreatic cells that can produce insulin on their own.
Is it our cells?
Well, each of us consists of about 10 trillion human cells, but we harbor as many as 100 trillion microbial cells.
They lived in cubicles the size of prison cells covered with chicken wire so you couldn't jump from one room into the next.
And, of course, it's the first satellite to go beyond the orbit of Jupiter on solar cells.
Our ability to program bacteria and program life opens up new horizons in cancer research, and to share this vision, I worked with artist Vik Muniz to create the symbol of the universe, made entirely out of bacteria or cancer cells.
Now, bees are the most sensitive when they're developing inside their brood cells, and I wanted to know what that process really looks like, so I teamed up with a bee lab at U.C. Davis and figured out how to raise bees in front of a camera.
