The clones for the library were taken from Arabidopsis, a flowering plant related to cabbage and mustard seen here. “You can think of <em>Arabidopsis</em> as the mouse of the botanical world,” USC Dornsife Dean Steve Kay said. Photo by Dawn Nagel.

Kay Lab Creates First Vast Library of Master Genetic Switches in Plants

July 17, 2014

USC Dornsife Dean Steve Kay and his researchers have created the first comprehensive library of genetic switches in plants, which will be available for scientists to use around the globe. The collection contains about 2,000…

Breaking the Genetic Code

May 7, 2014

Scientists at USC Dornsife have definitively demonstrated that large sets of variations in the genetic code that do not individually appear to have much effect can collectively produce significant changes in an…

You Are as Old as You Eat

January 29, 2014

Your best friend swears by the Paleo Diet. Your boss loves Atkins. Your sister is gluten-free, and your roommate is an acolyte of Michael Pollan. So who’s right? Maybe all four. In new research published this month in…

By examining whole genome sequencing data of living Europeans in more than 40 populations, USC Dornsife’s Peter Ralph has found that the genetics of all human beings are linked more closely than previously believed. Photo by Susan Bell.

We Are Family

August 7, 2013

New research by Peter Ralph of USC Dornsife has confirmed that everyone on Earth is related to everyone else on the planet. So the Trojan Family is not just a metaphor. Turns out, we’re also linked by genetics more…
