Researchers at the Washington School of Medicine were doing research with yeast, and noticed that two genes were more potent together than individually - in other words, the genes were strengthening each other.
Why this matters: Awhile ago, scientists were very taken aback to discover humans only had about 25,000 genes (it was a blow to the collective human ego). People had been expecting a much higher number because, frankly, we're a fairly complicated organism. This has led to a lot of research trying to work out how organisms get the most out of the genes they do have.
One way that this is speculated to happen is by genes interacting with each other. So gene A produces effect A, gene B produces effect B. But if you have both genes A and B then you get effect C. For instance, in the article I linked to, the effect is stronger expression of a trait than you would expect from simply combining the two genes.
There's a lot more to come from research like this; we know the DNA code, but we don't fully understand how it works.
Why is george washington university school of medicine ranked so low? is it not a good medical school?
