Mutations across animal kingdom shed new light on aging

The first study to compare the accumulation of mutations across many animal species has shed new light on decades-old questions about the role of these genetic changes in aging and cancer. Researchers from the Wellcome Sanger ...

Where on Earth did the water come from?

Earth's supply of water is incredibly important for its ability to sustain life, but where did that water come from? Was it present when Earth formed or was it delivered later by meteorites or comets from outer space?

Females supercharge sperm evolution in animals

Sperm size varies dramatically among different animal species. But why is sperm size so variable when they share the same job—to fertilize eggs? In a new article published in Nature Ecology and Evolution, researchers from ...

New algorithm uses online learning for massive cell data sets

The fact that the human body is made up of cells is a basic, well-understood concept. Yet amazingly, scientists are still trying to determine the various types of cells that make up our organs and contribute to our health.

Studies detail impact of mammal species decline in Neotropics

Mammal defaunation—the loss of mammals to extinction, extirpation and population decline—in the Neotropics and its adverse effects is the focus for two scientific papers produced recently by a group of scientists led ...
