Nanorobot hand made of DNA grabs viruses for diagnostics and blocks cell entry

Science Daily: Pharmacology News

A tiny, four-fingered 'hand' folded from a single piece of DNA can pick up the virus that causes COVID-19 for highly sensitive rapid detection and can even block viral particles from entering cells to infect them, researchers report.

Engineering viruses to kill deadly pathogens

Science Daily: Pharmacology News

In the new study, researchers successfully modified DNA from four types of phages to kill a deadly pathogen. Antimicrobial resistance is an urgent and growing global crisis. Researchers are exploring phages, viruses that infect bacteria, as a possible solution.

Researchers engineer in vivo delivery system for prime editing, partially restoring vision in mice

Broad Institute

Williams January 8, 2024 Credit: Susanna Hamilton, Broad Communications Researchers have developed virus-like particles that can deliver gene-editing cargo to cells, including those in the mouse brain. Prime editing, described in 2019 by Liu’s group, can make longer and more diverse types of DNA changes than other types of editing.

Can Global Genomic Surveillance Forecast the Next Pandemic?

PLOS: DNA Science

These factors are converging to enable both identification of novel infectious diseases as well as microbial resistance, before these threats can impact public health, write a team from the European Society for Clinical Microbiology and Infectious Diseases in Frontiers in Science. Work on vaccines ensued too.

Evolved prime editors are smaller and more efficient for therapeutic applications

Broad Institute

Their new editors are more efficient and specialized than previous versions, and are able to modify DNA in cultured cells and in animals that have been difficult to edit, including in immune system cells and inside the brain. In the new work, they focused on improving the heart of the prime editing system—the reverse transcriptase.
