If the trends of population growth and richer diets continue, experts say that by 2050 we will need to double the amount of crops we grow. Jonathan Foley, author of “Food: Feeding Nine Billion” in the May edition of National Geographic is director of the Institute on the Environment at the University of Minnesota.

Go back a few generations and odds are that your family lived and worked on a farm. We’re going to go back to our roots with USU professors Joyce Kinkead, Evelyn Funda, and Lynne McNeill, authors of “Farm: A Multi-Modal Reader,” which explores what farms, farming, and farmers mean to us as a culture.

The $1,000 genome has long been considered a milestone—the price at which sequencing can finally go mainstream. Companies such as 23andMe provide inexpensive consumer tests that examine about half a million points of a person’s DNA sequence. But until now investigating all 3 billion base pairs that make up a human’s genome cost $10,000 or more.
