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 ...

Juvenile African clawed frogs, Xenopus laevis, were exposed to commercial formulations of THX and CLO at high (100 ppm) and low (20 ppm) concentrations of the active ingredient. Mortality, growth, ...

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 ...

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 ...

A team of scientists led by the Department of Energy's Joint Genome Institute (JGI) and the University of California, Berkeley, is publishing this week the first genome sequence of an amphibian, the ...

A 3D anatomical atlas of the model organism Xenopus laevis (the African clawed frog) is now available to aid researchers in understanding embryonic development and metamorphosis—the intriguing process ...

Xenopus laevis tadpoles were held in 4 replicate vivaria for each of 4 treatments of neonicotinoid pesticides and one control treatment for at least one month (Control media, thiamethoxam high ...

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 ...
