Researchers should consider stress as a potential variable in studies 7, and environmental enrichment can reduce stress in laboratory rats and mice. Measurable parameters considered to be linked ...

A breakthrough was achieved in 1909 when researchers managed for the first time to mate mice with each other over many generations. The animals from this inbred line were homogeneous, so that the ...

We’re finally realising that many species are Now, Li Zhang at the University of Southern California (USC) and his colleagues have filmed what happened when they presented laboratory mice with a ...

President Joe Biden’s former director of the National Institutes of Health said that the institutes never funded “transgender ...

A new Cedars-Sinai study demonstrates how gut bacteria can influence the development of blood vessel inflammation in ...

Mounting scientific evidence indicates that environmental enrichment improves the welfare of laboratory mice, but most facilities worldwide still use standard housing (i.e., mostly barren “shoebox” ...

Led by Alexandros Vezyrakis, with Anja Guenther and Valeria Mazza, the team tested over 100 mice both in semi-natural enclosures (mimicking their wild habitats) and later in controlled lab arenas. The ...

What Are Humanized Mice? Humanized mouse models are mice that scientists modify in the laboratory to host human cells, tissues, or genes, or portions of a person’s microbiome. Researchers use ...

Researchers at Cold Spring Harbor Laboratory have discovered a way to target proteins in human cells that lead to pancreatic ...

Inter-male aggression in mice continues to challenge laboratory animal husbandry personnel, as intervention strategies are typically applied at the cage level without a good understanding of how ...

head of the Stem Cell Biology Developmental Genetics Laboratory at London's Francis Crick Institute, told CNN. "As it is, we ...
