Hotter temperatures may render natural insect repellents less effective against mosquitoes, according to a new study.

An aggregation of wood frog egg masses in a pond following spring breeding. Wood frogs are explosive, synchronous breeders that arrive at temporary freshwater ponds soon after snowmelt to reproduce ...

When Xenopus frog eggs are experimentally ruptured, their cytoplasm rearranges itself to form compartments similar to cells, according to a study published October 31 in Science. The researchers, led ...

Another focus of our lab is to analyze early frog development when fertilized frog eggs undergo developmental cell divisions that result in reduced cell and nuclear size. We will determine what ...

Frogs have thrived for hundreds of millions of years, spreading across virtually every corner of Earth, from tropical jungles ...

Hotter temperatures may render natural insect repellents less effective against mosquitoes, according to a new study.

Cells also differ in size. Although cells can be quite large — consider a frog's egg, for example — most are too small to see with the naked eye. Indeed, the development of light microscopy ...

Instead, the hollow interior fills with water and provides a home for new life to begin — via frog eggs. A new species of tree frog was discovered laying its eggs in the tiny bamboo shaft ...
