So your blood cells, your red blood cells, are coated with sugars, and the chemical structures of those sugars determine your blood type.
But for those of you who share the blood type O with me, what this means is that we have this chemical structure on the surface of our blood cells: three simple sugars linked together to make a more complex sugar.
And the typical scenario is a patient would have a tumor detected, and the tissue would be removed in a biopsy procedure and then sent down to a pathology lab where that tissue would be analyzed to look for chemical changes that might inform the oncologist about the best course of treatment.
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.
While the exact cause of depression isn't clear, research suggests that most mental disorders develop, at least in part, because of a chemical imbalance in the brain, and/or an underlying genetic predisposition.
That could be a chemical process."
When a virus invades a bacterium, Cas proteins cut out a segment of the viral DNA to stitch into the bacterium’s CRISPR region, capturing a chemical snapshot of the infection.
We see it either as sound, or we see it as video, or we see it as photographs, or we see it as chemical sensors, but we never have yet put it all together into one interesting picture.
So here, you've got this valley with this incredible alien landscape of pillars and hot springs and volcanic eruptions and earthquakes, inhabited by these very strange animals that live only on chemical energy coming out of the ground.
About half the chemical energy is converted into electricity, and the remainder into heat, which is used to break down limestone into lime and carbon dioxide.
Radiochemists at the hospital can use a series of chemical reactions to attach the radioactive fluorine to different molecules, creating radiotracers.
Scientists have found that music causes our brains to release a natural painkiller known as oxytocin and a feel-good chemical, dopamine.
Nowadays, any species of venomous snakes, any species of spider, any species of scorpion, has its own venom signature, if you will, made out of dozens, if not hundreds, of chemical compounds.
You see, venom is that kind of huge library of chemical compounds that are available to us, that are produced by hundreds of thousands of live creatures.

To those disabled CRISPR scissors, shown in blue, we attached a second protein in red, which performs a chemical reaction on the DNA base C, converting it into a base that behaves like T. Third, we had to attach to the first two proteins the protein shown in purple, which protects the edited base from being removed by the cell.
