Discovery could reshape RNA editing with DNA-guided CRISPR

A team of engineers at the University of Florida has developed a new form of CRISPR technology that could make diagnostics and treatments safer, more precise, and more affordable, while opening the door to entirely new ways ...

Early human embryonic cells may be vulnerable to SARS-CoV-2 infection

A University of California, Riverside study reports that cells in the earliest stages of human development could be susceptible to infection by SARS-CoV-2, which causes COVID-19, offering new insight into how the virus interacts ...

No brain required: This is how the single-celled Stentor learns

Scientists have known for more than a century that a single-celled organism with no nerve cells—much less a brain—can behave in ways that resemble learning. But those observations only went so far. How the organism did that ...

AI-designed miniproteins switch key cell receptors on and off

G protein-coupled receptors, or GPCRs, sit in the plasma membrane, the boundary that defines the inside and outside of a living cell. They communicate with nearly every physiological process in our bodies—from the ability ...
