The DNA-cutting proteins central to CRISPR-Cas9 and related gene-editing tools originally came from bacteria, but a newfound variety of Cas proteins apparently evolved in viruses that infect bacteria. The new Cas proteins were found in the largest known bacteria-infecting viruses, called bacteriophages, and are the most compact working Cas variants yet discovered — half the size of today’s workhorse, Cas9.

A big advance in carbon capture technology could provide an efficient and inexpensive way for natural gas power plants to remove carbon dioxide from their flue emissions, a necessary step in reducing greenhouse gas emissions to slow global warming and climate change. Developed by researchers at the University of California, Berkeley, Lawrence Berkeley National Laboratory and ExxonMobil, the new technique uses a highly porous material called a metal-organic framework, or MOF, modified with nitrogen-containing amine molecules to capture the CO2 and low temperature steam to flush out the CO2 for other uses or to sequester it underground.

As the number of COVID-19 cases continue to escalate in the United States, healthcare providers across the country are dealing with a shortage of personal protective equipment, which has left many workers on the frontlines vulnerable to catching and transmitting the virus. In the Bay Area, an initiative called Shield the Bay is aiming to address this PPE crunch.

Thanks to Fast Grants, a rapid funding program activated six weeks ago, a group of seven COVID-19 research projects has started at UC Berkeley that could turn up new diagnostic and potential treatments for the infection within months. One project is being lead by Daniel Nomura, a professor of chemistry, molecular and cell biology, and nutritional sciences and toxicology. He is working with a group of investigators, and fellow professors, planning to use innovative chemical biology approaches to develop novel therapeutics against COVID-19.
