When scientists from the Leibniz Institute of Plant Genetics and Crop Plant Research in Germany sequenced the genome of barley, they were thinking primarily about the impact on food. Understanding the genetics behind certain traits could help us breed barley varieties that have built-in resistance against disease, or that contain more fiber. (Contrary to popular understanding, there's actually a lot of overlap between what we might think of as genetic engineering and what we might think of as breeding. Crop researchers can use genome maps to select specific plants to cross pollinate, enabling them to reliably breed a trait into a new variety much faster than was previously possible.)
But, this is barley. And we don't just eat barley. With this plant, sequencing the genome also has implications for the way we brew beer. At Popular Science, Martha Harbison explains what we're learning about barley's genetic code and why it matters in beer making. In particular, she says it's significant that the researchers sequenced the genomes of more than one variety of barley.
Why should aspiring homebrewers care? Because two-row and six-row barley behave slightly differently in the mash, which can have profound effects on brewing efficiency and characteristics of the finished beer (a complex phenomenon I'll get into in a future column). I figured anyone nerdulent enough to want to know about genetic differences of cultivars would be curious as to which kind of barley was used in the single-nucleotide-variation study.

NASA today announced that astronomers studying data from NASA’s Great Observatories have found the best evidence yet for “cosmic seeds in the early universe that should grow into supermassive black holes.”
Could you recover a murder victim’s last sight of their killer by extracting it from the retina? Little more than a century ago, forensic scientists thought it might be possible. After all, in 1877 physiologist Wilhelm Friedrich Kühne was able to develop a simple image from an albino rabbit’s dissected eyeball. (Above, the two images […]
