Hypercompact CRISPR enzyme from bacteriophages expands genome editing toolbox

A recently discovered hypercompact CRISPR enzyme found only in huge bacteriophages, and known as CRISPR-CasΦ, is functional, a new study by Patrick Pausch, Jennifer Doudna and colleagues reports, and it provides a powerful new tool in the CRISPR genome editing toolbox, including because it can target a wider range of genetic sequences compared to Cas9 and Cas12

Scientists gain insights into how parasitic bacterium gives rise to lesions

Bacteria of the genus Bartonella are parasites that can be transmitted to humans via insect bites and animal scratches, resulting in an infection known as "bartonellosis." Cat-scratch disease and trench fever are forms of bartonellosis caused by different Bartonella species infecting humans.
