Functional definition of NrtR and the discovery of its acetylation represents a first paradigm for linking protein acetylation to bacterial central NAD⁺ metabolism.

Mitochondrial fusion enables a metabolic transition during spermatogenesis.

Population response magnitude predicts how well an image will be remembered, in both monkey inferotemporal cortex and neural networks trained to categorize objects.

AurkA is imported into mitochondria at interphase, and it induces organelle elongation and enhances ATP production when over-expressed.

SPIN1, a nucleolar protein, plays an oncogenic role by suppressing the tumor suppressor p53's function via regulation of the uL18-MDM2-p53 pathway.

Meiotic cells inhibit two distinct steps of replisome assembly with multiple kinases to prevent DNA replication between Meiosis I and Meiosis II.

Visualization of the sliding clamp in DNA mismatch repair shows how a transient complex is activated.

The interplay between the cytokine TGFβ and the PD-1/PD-L1 pathway promotes CD8+ T cell anergy and tolerance towards transplanted tissues.

Tertiary folding of the Rev-response element (RRE) in HIV RNA ensures the rapid formation of the Rev-RRE viral ribonucleoprotein particle via a two-step process.

Building on previous work (Jinek et al., 2013), we report a simple and robust system to achieve high fidelity and high efficiency (30% of homologous recombination) genome engineering by homology-directed repair pathway in human cells using cell cycle synchronization and timed delivery of Cas9 ribonucleoprotein complexes.
