    A Neighborhood On A Crayfish

    If you're a crayfish, North Carolina is where it’s at. In general, the state is among the most biologically-diverse for several reasons. Additionally, there are a couple of thoughts as to why we live in the Mudbug Mecca. In a way, crayfish are islands unto themselves. Most species carry with them Branchiobdellida, a species of worm that live life on the clawed critter.

    The Predictive Power Of The Junk In Your Genome

    You are you because of a unique combination of your parents’ genes, coded into the strands of DNA molecules, coiled tightly around an “X-shaped” structure. This is a chromosome, and you have 23 pairs of them, deep down in the nucleus of all 37 trillion cells in your body.

    Dr. Beth Sullivan, Associate Professor of Molecular Genetics and Microbiology at Duke University, studies chromosome rearrangements in her lab and how they may cause disease.

    Preserved Paleo Protein Provides Perspective on Dino Family Tree, and Maybe Life in Space. Wait. What?

    You are a paleontologist on expedition hunting dinosaur fossils.  For all your efforts, you’ve unearthed just a few bone fragments. Back at the lab, you and your team determine that, based on their shape and size, you’re looking at a colossal waste of time and resources. But a new tool is emerging which allows us to use dinosaur DNA to better understand prehistoric evolutionary trees. It may also help to find life on Mars, or treat human diseases.
