The common laboratory frog Xenopus laevis has puzzled researchers because it has twice the normal number of genes. A newly published genome sequence shows why: between 15 and 20 million years ago ...

Xenopus, meaning "strange foot," is a genus of more than 20 frog species native to sub-Saharan Africa. When biologists discovered in the early 20th century that these frogs were unusually ...

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 ...

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 ...

African clawed frogs used to be the best human pregnancy tests in the world. Doctors would inject a woman's urine into the back of a female frog; if positive, the frog would lay eggs. Frog or ...

Can scrambled eggs unscramble themselves? Well, sort of. The cytoplasm of ruptured Xenopus frog eggs spontaneously reorganizes into cell-like compartments, according to a study by researchers at ...

When a Xenopus frog is deeply wounded, its skin can regenerate without scarring. Researchers have found that cells under the skin contribute to this regeneration after an excision injury.

The frog test works because a pregnant woman’s urine contains a hormone called human chorionic gonadotropin, or hCG. Most modern pregnancy tests rely on the detection of hCG using other means ...

These xenobots, named for the African frog Xenopus laevis from which they are made, could already move around, display collective behavior and heal themselves.

"It is known that patients with mutations in the Hoxc13 gene have defects in the growth of hair and nails. In our study, we were able to block the formation of claws in the clawed frog by ...

Meet Xenopus, the African Clawed Frog: a strange creature that has opened a window into understanding ourselves in unexpected ways. Join Shane in this episode of Human Footprint as he talks to ...
