Grow and eat your own vaccines?
September 16, 2021
The future of vaccines may look more like eating a salad than getting a shot in the arm. Scientists at UC San Diego, UC Riverside and Carnegie Mellon University are studying whether they can turn edible plants like lettuce into mRNA vaccine factories.

UC San Diego NanoEngineers to lead MRSEC research thrust on Predictive Assembly July 8, 2020
In some ways, the field of materials science is where the pharmaceutical sciences were twenty years ago. A team of University of California San Diego researchers is working to change that. The team makes up the "predictive assembly" research thrust of the new $18M Materials Research Science and Engineering Center (MRSEC) funded by the National Science Foundation (NSF). Today, computational and predictive tools are used in the pharmaceutical industry in order to design "small molecule" drugs with particular properties and behaviors. The challenge is that the design-before-you-synthesize approach hasn't worked for the larger-scale materials that are critical for many applications beyond small-molecule drugs. That's the work that will be done by the team led by nanoengineering professors Andrea Tao and Tod Pascal from the UC San Diego Jacobs School of Engineering. Full Story
UC San Diego NanoEngineers to lead MRSEC research thrust on Living Materials July 8, 2020

The team's big idea is to incorporate living organisms, either from plants or microbes, into their new materials. Living organisms have evolved over billions of years to perform complex functions and to sense the environment around them. Synthetic materials still lag far behind what biological systems can accomplish. The UC San Diego researchers are asking: why not use biology to program materials? Full Story
