Scientists have developed a CRISPR-based gene-drive system that inactivates a gene rendering bacteria antibiotic-resistant. The new system leverages technology developed by UC San Diego biologists in insects and mammals that biases genetic inheritance of preferred traits called “active genetics.”
A multi-institutional research team has been awarded a $2 million National Science Foundation grant to build an interdisciplinary research program that explores how the brain learns and stores information.
Scientists have found the most effective CRISPR shield ever discovered in viruses. They discovered a remarkable new strategy that some bacteria-killing viruses, or phages, employ: after they infect bacteria, these phages construct an impenetrable “safe room” inside of their host.
Scientists thought they knew everything there was to know about how and why bacterial cells moved around, but back-to-back articles in Nature by UC San Diego’s Terence Hwa reveal how little they understood bacteria movement en masse.
At the start of the day, we all do it. We reflexively reach for our phones. As the day winds down, many of us can’t help but do the same. We lie in bed as the luminous glow of our phones—along with TVs and tablets, in many cases—shines into our eyes.
Liz Specht, Ph.D.’ 14, Biological Sciences, is the associate director of science and technology at the Good Food Institute, a non-profit organization that supports plant-based and cultivated alternatives to conventional meat products.
Scientists have gained a new understanding of how ultra-resilient tardigrades, or “water bears,” are protected in extreme conditions. The researchers discovered that a protein named Dsup binds and forms a protective cloud against extreme survival threats such as radiation damage.
Studying natural defenses in maize, a staple of diets around the world, UC San Diego biologists describe how they combined an array of scientific approaches to clearly define six genes that encode enzymes responsible for the production of key maize antibiotics known to control disease resistance.
Biologists have provided the first example of cargo within bacteriophage cells transiting along treadmill-like structures. The discovery demonstrates that bacteria have more in common with sophisticated human cells than previously believed.
