The CRISPR technology has already been used to change the DNA in the cells of mice and monkeys, other organisms as well.
And scientists in Philadelphia showed they could use CRISPR to remove the DNA of an integrated HIV virus from infected human cells.
The opportunity to do this kind of genome editing also raises various ethical issues that we have to consider, because this technology can be employed not only in adult cells, but also in the embryos of organisms, including our own species.
It's a mechanism that allows cells to record, over time, the viruses they have been exposed to.
And importantly, those bits of DNA are passed on to the cells' progeny, so cells are protected from viruses not only in one generation, but over many generations of cells.
This allows the cells to keep a record of infection, and as my colleague, Blake Wiedenheft, likes to say, the CRISPR locus is effectively a genetic vaccination card in cells.
As I'm going to tell you now, we recognized that that activity could be harnessed for genome engineering, to allow cells to make a very precise change to the DNA at the site where this break was introduced.
The reason we envisioned using the CRISPR system for genome engineering is because cells have the ability to detect broken DNA and repair it.
So if we have a way to introduce double-stranded breaks into DNA at precise places, we can trigger cells to repair those breaks, by either the disruption or incorporation of new genetic information.
So if we were able to program the CRISPR technology to make a break in DNA at the position at or near a mutation causing cystic fibrosis, for example, we could trigger cells to repair that mutation.
I actually think that the first applications of the CRISPR technology are going to happen in the blood, where it's relatively easier to deliver this tool into cells, compared to solid tissues.
And here we find that we can use these systems to test the application of this technology in particular tissues, for example, figuring out how to deliver the CRISPR tool into cells.
You could be attacked by white blood cells in the arteries.
And this is why I have been looking into solar cells and solar panels.
That's why it is possible to use existing solar cells on the roof of a hut to act as a broadband receiver from a laser station on a close by hill, or indeed, lamp post.
And the same is true for translucent solar cells integrated into windows, solar cells integrated into street furniture, or indeed, solar cells integrated into these billions of devices that will form the Internet of Things.
Since females only have X's to pass on in their egg cells, and males can give either an X or a Y in their sperm cells, the sex is determined by the father and the chance of producing a male or a female is 50/50.
These detectors are specialized nerve cells called nociceptors that stretch from your spinal cord to your skin, your muscles, your joints, your teeth and some of your internal organs.
Just like all nerve cells, they conduct electrical signals, sending information from wherever they're located back to your brain.
But, unlike other nerve cells, nociceptors only fire if something happens that could cause or is causing damage.
You'll feel the metal, and those are your regular nerve cells.
When cells are damaged, they and other nearby cells start producing these tuning chemicals like crazy, lowering the nociceptors' threshold to the point where just touch can cause pain.
When cells are damaged, they release a chemical called arachidonic acid.
Cortisol is a major stress hormone involved in making skin cells churn out oily lipids from special glands called sebaceous glands.
Then that cell divides and we are two cells, then four, then eight.
These cell divisions, by which we go from a single cell to 100 trillion cells, are called growth.
And growth seems like a simple thing because when we think of it, we typically think of someone getting taller or, later in life, wider, but to cells, growth isn't simple.
And in a neighborhood of 100 trillion cells, some times things go wrong.
At every stage, the incorrect instructions are passed along to the cells' offspring.
Or, a routine blood test might count too many white cells or elevated liver enzymes.
