For biology:

- Various advancements in stem cell research. Eg: skin cells into stem cells. - The creation of a living organism with a completely synthetically constructed genome. - The sequencing of the human genome. - Nearly all of neuroscience.

Those example are all technology. Astounding technology, sure, but still technology. They're not great theories or discoveries. (And by "discovery" I mean a discovery of something that exists in nature -- like plate tectonics -- not discovering a way to make something.)

Neuroscience is a biggie. Finally getting much closer to really understanding consciousness.
