Richard ("Rick") Young is a Professor of Biology at the Massachusetts Institute of Technology and a member of the Whitehead Institute. His area of expertise is the regulation of gene expression in eukaryotes.
He was interviewed by Jorge Conde and Hanne Winarsky on a recent podcast (Feb. 1, 2021) where the main topic was "From Junk DNA to an RNA Revolution." They get just about everything wrong when they talk about junk DNA including the Central Dogma, historical estimates of the number of genes, confusing noncoding DNA with junk, alternative splicing, the number of functional RNAs, the amount of regulatory DNA, and assuming that scientists in the 1970s were idiots.
In this episode, a16z General Partner Jorge Conde and Bio Eats World host Hanne Winarsky talk to Professor Rick Young, Professor of Biology and head of the Young Lab at MIT—all about “junk” DNA, or non-coding DNA.
Which, it turns out—spoiler alert—isn’t junk at all. Much of this so-called junk DNA actually encodes RNA—which we now know has all sorts of incredibly important roles in the cell, many of which were previously thought of as only the domain of proteins. This conversation is all about what we know about what that non-coding genome actually does: how RNA works to regulate all kinds of different gene expression, cell types, and functions; how this has dramatically changed our understanding of how disease arises; and most importantly, what this means we can now do—programming cells, tuning functions up or down, or on or off. What we once thought of as “junk” is now giving us a powerful new tool in intervening in and treating disease—bringing in a whole new category of therapies.
Here's what I don't understand. How could a prominent scientist at one of the best universities in the world be so ignorant of a topic he chooses to discuss on a podcast? Perhaps you could excuse a busy scientist who doesn't have the time to research the topic but what excuse can you offer to explain why the entire culture at MIT and the Whitehead must also be ignorant? Does nobody there ever question their own ideas? Do they only read the papers that support their views and ignore all those that challenge those views?
This is a very serious question. It's the most difficult question I discuss in my book. Why has the false narrative about junk DNA, and many other things, dominated the scientific literature and become accepted dogma among leading scientists? Soemething is seriously wrong with science.
