The universal eukaryotic DNA replication kinetics is the consequence of simple physicochemical rules resulting from the localisation of potential replication origins at discrete sites and the diffusion of limiting origin firing factors in the nuclear space.
Advances in techniques for analysing single cells and tissues have inspired an international effort to create comprehensive reference maps of all human cells - the fundamental units of life - as a basis for both understanding human health and diagnosing, monitoring and treating disease.
Targeted SOCS3 null mice reveal that maturation of cortical bone comprises both pore closure and accumulation of high density bone, requiring local suppression of gp130-STAT3 in osteocytes and subsequent osteoclastogenesis.
Super-resolution microscopy sets a new strategy to comprehend the membrane organization of γ-secretase at single complex resolution identifying nanodomain associations and its diffusion in situ in the living membrane.
A gain-of-function in a new chemical defense resulted in no trade-offs and and independent evolution between novel and ancestral defenses, suggesting low redundancy among different defensive chemicals.
The gene Odd-paired is a late-acting regulator of zygotic gene expression, functioning coordinately with Zelda to influence chromatin accessibility and affecting genes expressed along both axes of Drosophila embryos.
