The genome sequence of the most common laboratory frog reveals that it originated when different frog species hybridized and the genome doubled, paralleling events that led to the origin of ...

Pregnancy tests today are as simple as peeing on a toothbrush-size stick and waiting a few minutes. Chemicals in the sticks can detect a key pregnancy hormone: human chorionic gonadotropin (hCG). Back ...

Researchers have used mRNA sequences, rather than DNA, to more efficiently create a reference database that can be used for proteomic analysis of Xenopus frogs. The researchers used their reference ...

Because of its large eggs, Xenopus laevis -- the African clawed frog -- has become a popular model for studying embryo development and cell biology. It's smaller cousin, X. tropicalis, is now gaining ...

During the genome-assembly process for a diploid organism (one, like humans, that has two sets of chromosomes), a single reference chromosome sequence is generated to correspond to each chromosome ...

The number of clawed frogs used worldwide in research could soon be a fraction of the current number, following new research at the University of Portsmouth. Xenopus are aquatic frogs native to ...

A female African clawed frog, Xenopus laevis, was housed at the Biological Resources Facility of North Carolina State University in a tank with two other females. The frog was ∼1.5 years old and was ...

The development of hair was of central importance for the evolution of mammals and, thus, also of humans. However, the evolutionary origin of the genetic program of hair was previously unknown. An ...
