The CRISPR-Cas system, naturally found in many prokaryotes, is widely used for genome editing. CRISPR arrays in the bacterial genome, derived from the genome of invading viruses, are used to generate a CRISPR RNA that guides the Cas enzyme to destroy repeat viral invaders. Recently, an unexpectedly compact CRISPR-Cas system was identified in huge bacteriophages. Pausch et al . show that even…

Intrinsically safe designs and a staged transparent development process will be essential
Drugs of abuse are thought to promote addiction in part by “hijacking” brain reward systems, but the underlying mechanisms remain undefined. Using whole-brain FOS mapping…
To understand vulnerable glaciers, climate scientists extract ice from continent’s remote and stormy coast
The pursuit of artificial general intelligence (AGI) continuously demands higher computing performance. Despite the superior processing speed and efficiency of integrated photonic circuits, their capacity…
A novelist’s venture into nonfiction is filled with deep insights about life on Earth but may leave some wanting more
Division of labor among resident tissue macrophages is vital for proper tissue function during homeostasis.
Jupiter’s moon Io hosts extensive volcanism, driven by tidal heating. The isotopic composition of Io’s inventory of volatile chemical elements, including sulfur and chlorine, reflects…
