Gestational age estimation models derived from newborn screening bloodspot samples are effective on data obtained from both heel prick and cord blood samples in low-resource settings.

Ignoring the probability of species variation when reporting observations about biological processes leads to misinterpretation of the experimental data.

Guidelines governing research into embryos need to be updated in a way that reflects the moral status of synthetic human entities generated using the methods of synthetic biology.

Studies of the house mouse Mus musculus have provided important insights into mammalian biology, and efforts to study wild house mice and to create new inbred strains from wild populations have the potential to increase its usefulness as a model system.

Wild baboons are an excellent model to study complex evolutionary processes such as speciation and hybridization, as well as the links between sociality, longevity and reproductive success.

The deer mouse (Peromyscus) has emerged as a model system for studying many aspects of biology, supported by extensive historical knowledge of its fascinating and varied natural history.

A text-mining study suggests that about half of the papers reporting the results of experiments on mice do not report the sex and age of the mice.

Establishment of the acinar lineage in the salivary gland requires SOX2 and parasympathetic nerves.

A combination of genetic and molecular assays revealed that transcription factor Tfcp2l1 provides the basis for cell patterning and physiologic coordination in kidney collecting ducts.
