University of Portsmouth researchers have been awarded a £654,625 grant from UK Research and Innovation (UKRI) to tackle a ...

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 ...

Hybridization of eggs and sperm from closely related species can give rise to genetic diversity, or can lead to embryo inviability owing to incompatibility. Although central to evolution, the cellular ...

Multicellular organisms develop with a remarkable consistency, maintaining a precise body plan in the face of genetic polymorphism or environmental fluctuations 1. Yet, size and shape differ ...

The African clawed frog, Xenopus laevis, is a palm-sized, greenish-gray animal that hails from the ponds and rivers of sub-Saharan Africa, where it lived for millions of years without anyone injecting ...

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 ...

This is a preview. Log in through your library . Abstract Components of the feeding behavioral repertoire of captive African clawed frogs were determined and described. Sequential transitional ...

This is a preview. Log in through your library . Abstract Model organisms are often assumed to be representative of some more inclusive taxon of which the species is a part. This assumption leads to ...

Neurons have the amazing ability to self-organize into highly refined networks. I am interested in how these networks form. I am especially interested in the molecular pathways underlying this process ...

Pregnancy tests did not always come in an easy-to-use, sterile kit that provided almost immediate results. Less than a century ago, women had to rely upon frogs instead. In 1938, Dr. Edward R. Elkan ...

A fungus that grows on the backs of frogs may be responsible for the extinction of dozens of species, say the authors of a study published in Thursday’s issue of Nature. Amphibian chytrid fungus seems ...
