Exploring your DNA // Cellular Innards Revealed

Genomic exploration by Carl Zimmer
Genomic exploration by Carl Zimmer
This week on How on Earth we speak with 2 notables. NY Times columnist Carl Zimmer describes his exploration of his genome sequence, yes all 3 billion bases! See the series he has produced detailing this journey at https://www.statnews.com/feature/game-of-genomes/season-one/. Then, local cell biologist Gia Voeltz studies how the endoplasmic reticulum (ER) is formed. It is a large continuous structure in the cell, with many different functions and an elaborate shape. The ER was long thought to be the site of synthesis of proteins and other large biologically important molecules. Work in the Voeltz lab has expanded its role considerably. Visit her website to see beautiful moving pictures of ER in action: http://www.voeltzlab.org/#!research-projects/c10g1

The Universe Within // De-Extinction

The Universe Within (starts at 4:40) Within each and every one of us is the history of life on this planet, the planet itself and the entire universe.  This is the theme of a new book “The Universe Within.”  The author, Neil Shubin, is a professor of Paleontology and Evolutionary Biology at the University of Chicago.  Starting with what physically constitutes a human being and what makes a human life possible, Shubin surveys many domains of science to find out what we can learn about what’s out there from what’s inside of us.   It’s a fantastically broad scope, bringing together the common history of Rocks, Planets and People.  As professor Shubin explains to How On Earth’s Chip Grandits, it is the very concept of this common history that binds all of these topics, which are normally found scattered throughout disparate domains of science and academia.

De-Extinction (starts at 14:15) You may think that when a species dies, it’s gone forever.  But with enough motivation, scientists might be able to return some species to life.  Popular science writer Carl Zimmer has written about “de-extinction” in the cover story of April’s issue of National Geographic magazine. So, is the movie Jurassic Park a good primer on de-extinction?
