A duplicated gene evolved into a switch that determines sex in frogs, revealing how evolution can safely reshape critical ...

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 ...

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 "Hogben" ...

Behavioral Ecology and Sociobiology, Vol. 62, No. 11 (Sep., 2008), pp. 1821-1829 (9 pages) We examined the behavioral and developmental responses of Xenopus laevis larvae to their mirror images in ...

WOODS HOLE, Mass.— Proteomics, the study of large groups of proteins, can enhance our understanding of a wide range of organisms, with applications in medicine and developmental biology. Such analyses ...

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 ...

Proceedings of the National Academy of Sciences of the United States of America, Vol. 82, No. 16 (Aug. 15, 1985), pp. 5413-5417 (5 pages) DG81 is a cDNA clone derived from a subtracted library ...

Scientists have used Xenopus laevis tadpoles to tease out the genetic and biological mechanisms that enhance disease tolerance, and have identified drugs that can keep the tadpoles alive even in the ...

African clawed frogs have more in common with humans than you might think, according to their newly sequenced genome, which shows a surprising number of commonalities with the human genome. The frog ...
