Epigenetic restriction of herpes simplex virus occurs in a biphasic manner, in which ATRX maintains viral heterochromatin after an initial phase of chromatin deposition.

ATR protects stem cell genomes by activating a transcriptional response mediated by totipotency genes, conferring trophoblast differentiation potential, the derepression of which in somatic cells might favour cancer features emergence.

ATR/Chk1 contribute to G2 arrest in developing tracheoblasts, and arrest in G2 facilitates cellular and hypertrophic organ growth.

ATM plays an important role in maintaining the fidelity of DNA repair through the regulation of ARP8 phosphorylation to prevent the chromosome abnormality.

During meiosis, budding yeast use a checkpoint involving the protein Mec1 to prevent the formation of double-strand breaks in DNA that has not completed replication.

Bumblebees use invisible temperature patterns on flowers to make foraging decisions.

Two recently discovered transcription factors stop cells from dividing when plants face extreme heat and DNA damage.

Simultaneous quantification of each of the main motor programs in the roundworm C. elegans yields new insights into the neural mechanisms that coordinate animal behavior.

Subterranean fossil bone hosts a living microbiome different from the surrounding sediment without evidence of original protein preservation.

GTP binding induces rearrangement of S-OPA1 assembly on membrane and thus triggers membrane remodeling with reduced curvature.
