The team found the world’s largest mammal pushes its heart to its limits

Thanks to the ubiquity of electric light, less and less of the planet falls genuinely into darkness any more.

How Cities and Lights Drive the Evolution of Life

Urbanization and the spread of artificial light are transforming all of earth’s species, bringing about a host of unintended consequences

Heliconius charithonia is one of the species of butterflies whose wing patterns scientists scrutinized to better understand the evolutionary process. This butterfly is wild-type; the genetically edited H. charithonia wings have wider swathes of yellow.
