DNA dumpster diving

Since the 1960s, it's largely been assumed that most of the DNA in the human genome was junk. It didn't encode proteins—the main activity of our genes— so it was assumed to serve no purpose. But Assistant Professor of ...

Origins of genomic 'dark matter' discovered

A duo of scientists at Penn State University has achieved a major milestone in understanding how genomic "dark matter" originates. This "dark matter"—called non-coding RNA—does not contain the blueprint for making proteins ...

Microbial genomes help propose phylum name

At the phylum level, the number and diversity of unknown microbes still far outnumber those being studied. Metagenomics and single-cell genomics are tools helping researchers learn more about the "biological dark matter" ...
