This is pretty amazing. The device you see there is a home genome sequencer. Like, for sequencing your genome. And it’s about the size of a big microwave.
What exactly will you do with it? You will sequence your genome. At home.
Whether that information is useful to your or not, I can’t say, but do you remember when it took the combined powers of like ten universities and a hundred researchers to sequence the human genome? And now you can get a complete genetic profile of yourself (or anyone you can get a tissue sample of) without leaving the den.
