Over 160,000 new viruses discovered by AI

Science Daily: Pharmacology News

161,979 new RNA viruses have been discovered using a machine learning tool that researchers believe will vastly improve the mapping of life on Earth and could aid in the identification of many millions more viruses yet to be characterized.

RNA for the first time recovered from an extinct species

Science Daily: Pharmacology News

A new study shows the isolation and sequencing of more than a century-old RNA molecules from a Tasmanian tiger specimen preserved at room temperature in a museum collection. This resulted in the reconstruction of skin and skeletal muscle transcriptomes from an extinct species for the first time.

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. By Sarah C.P. They also delivered prime editors to the mouse brain, and did not detect any off-target editing.

Evolved prime editors are smaller and more efficient for therapeutic applications

Broad Institute

We hope these new prime editors will become an integral part of the gene editing field, which has created so much promise and progress in the life sciences and in medicine.” Reverse transcriptase proteins that copy RNA templates into strands of DNA are found naturally in all plant and animal cells and in many viruses.
