Amazon mollies don't need a man, and never will. A new study finds they can purge and repair genetic mutations that would otherwise plague a self-cloning species.

The tiny Amazon molly (Poecilia formosa) has always fascinated researchers because, according to the rules of evolution, it shouldn't have survived as a species, let alone thrive as a species for over ...

After cold winters, invertebrates such as honeybees and paper wasps seem to disappear and then suddenly return in large ...

Even in the ultra-dry Atacama Desert, tiny soil-dwelling nematodes are thriving in surprising diversity. Scientists found ...

Scientists uncover hidden life thriving beneath the surface of the driest desert, revealing how soil ecosystems survive ...

The Atacama Desert is one of the driest places in the world. Some areas get very little rain each year. The soil is salty, and in some places it even contains harmful elements like arsenic.

We report on a new study from France, which indicates that dogs and cats may help to spread invasive flatworms.

A rare Japanese ant is the only species known to lack female workers and males; all of its young develop into parasitic queens that try to take over other colonies.

The Amazon molly reproduces without sex. A genomic copy-and-paste trick called gene conversion may explain how it avoids evolutionary meltdown.

The kick-off signal for puberty begins in the brain. Specifically, in the hypothalamus, where specific neurons release a ...

Not all animals have brains, and all of them happen to be sea creatures. From the man-o-war to the sea cucumber, here are 12 animals that don’t have a brain and a quick look at how the heck they ...
