I always say that, you know, if you hire people just because they can do a job, they'll work for your money, but if they believe what you believe, they'll work for you with blood and sweat and tears.

The people who believed in the Wright brothers' dream worked with them with blood and sweat and tears.

It's got this sort of soap opera-like lifestyle; they have sex, they burrow into your liver, they tunnel into your blood cells ... it's an incredibly complicated disease, but that's actually one of the things we find interesting about it and why we work on malaria: There's a lot of potential ways in.

One does an automatic malaria diagnosis in the same way that a diabetic's glucose meter works: You take a drop of blood, you put it in there and it automatically tells you.

The other thing is, you know, it would be even better if you didn't have to draw the blood.

And if you look through the eye, or you look at the vessels on the white of the eye, in fact, you may be able to do this directly, without drawing any blood at all, or through your nail beds.

Because if you actually look through your fingernails, you can see blood vessels, and once you see blood vessels, we think we can see the malaria.

So here's an image of red blood cells, and now we can actually map where the hemozoin and where the malaria parasites are inside those red blood cells.

We also have another hemozoin-oriented therapy for malaria: a way, in acute cases, to actually take the malaria parasite and filter it out of the blood system.

Mosquitoes only drink blood to lay eggs.

The revolution is called angiogenesis, and it's based on the process that our bodies use to grow blood vessels.

So why should we care about blood vessels?

The smallest blood vessels are called capillaries.

Now, the remarkable thing about blood vessels is that they have this ability to adapt to whatever environment they're growing in.

For example, in the liver, they form channels to detoxify the blood; in the lungs, they line air sacs for gas exchange.

We get most of these blood vessels when we're actually still in the womb.

And what that means is that as adults, blood vessels don't normally grow.

In women, blood vessels grow every month, to build the lining of the uterus.

And after injury, blood vessels actually have to grow under the scab in order to heal a wound.

And this is actually what it looks like, hundreds of blood vessels, all growing toward the center of the wound.

So the body has the ability to regulate the amount of blood vessels that are present at any given time.

It does this through an elaborate and elegant system of checks and balances, stimulators and inhibitors of angiogenesis, such that, when we need a brief burst of blood vessels, the body can do this by releasing stimulators, proteins called angiogenic factors, that act as natural fertilizer, and stimulate new blood vessels to sprout.

But what we now know, is that for a number of diseases, there are defects in the system, where the body can't prune back extra blood vessels, or can't grow enough new ones in the right place at the right time.

And under the microscope, you can see hundreds of these brown-stained blood vessels, capillaries that are feeding cancer cells, bringing oxygen and nutrients.

But cancers don't start out like this, and in fact, cancers don't start out with a blood supply.

Then they can't get any larger because they don't have a blood supply, so they don't have enough oxygen or nutrients.

Yet, without a blood supply, most of these cancers will never become dangerous.

So the body's ability to balance angiogenesis, when it's working properly, prevents blood vessels from feeding cancers.

In fact, if you actually block angiogenesis and prevent blood vessels from ever reaching cancer cells, tumors simply can't grow up.

Cancer cells mutate, and they gain the ability to release lots of those angiogenic factors, natural fertilizer, that tip the balance in favor of blood vessels invading the cancer.
