New method preserves viable fruit fly embryos in liquid nitrogen

Cryopreservation, or the long-term storage of biomaterials at ultralow temperatures, has been used across cell types and species. However, until now, the practical cryopreservation of the fruit fly (Drosophila melanogaster)—which ...

Tarantula's ubiquity traced back to the cretaceous

Tarantulas are among the most notorious spiders, due in part to their size, vibrant colors and prevalence throughout the world. But one thing most people don't know is that tarantulas are homebodies. Females and their young ...

A ribosome odyssey in mitochondria

Proteins make life and are made by ribosomes. In mitochondria, the repertoire of the mitoribosomal architectures turns out to be much more diverse than previously thought.

Novel major locus regulates beak evolution of ground tit

Classical quantitative genetics has found that most phenotypes are polygenic traits. Under this polygenic model, natural selection often acts on many loci simultaneously, resulting in the combination of a few loci with major ...
