Scientists at the University of California, Berkeley, have created a new COVID-19 therapeutic that could one day make treating SARS-CoV-2 infections as easy as using a nasal spray for allergies. In a new study published online in the journal Nature Communications, the team shows that these short snippets, called antisense oligonucleotides (ASOs), are highly effective at preventing the virus from replicating in human cells. When administered in the nose, these ASOs are also effective at preventing and treating COVID-19 infection in mice and hamsters.

To help in the relief effort after the Russian occupation of the Chernobyl Nuclear Power Plant in Ukraine in spring 2022, nuclear engineers at UC Berkeley are testing and refurbishing critical pieces of equipment to send to their collaborators at Chernobyl, the site of a 1986 nuclear explosion that spread radioactive contamination throughout the region.

Using an inexpensive polymer called melamine — the main component of Formica — chemists have created a cheap, easy and energy-efficient way to capture carbon dioxide from smokestacks, a key goal for the United States and other nations as they seek to reduce greenhouse gas emissions.
