The probe, which launches Sunday, will attempt to solve enduring mysteries about the sun

The corn variety Sierra Mixe grows aerial roots that produce a sweet mucus that feeds bacteria. The bacteria, in turn, pull nitrogen out of the air and fertilize the corn. If scientists can breed this trait into conventional corn, it could lead to a revolution in agriculture.

The Corn of the Future Is Hundreds of Years Old and Makes Its Own Mucus

This rare variety of corn has evolved a way to make its own nitrogen, which could revolutionize farming

More like not-so-great white shark. Like today's sharks, prehistoric sharks sported a vast array of body sizes, shapes, and ornamentations.

Birds don’t fly across wide Amazonian rivers like the Rio Negro.

How Amazon Rivers Play a Role in the Evolution of Birds

Rivers are natural boundaries for evolving populations. But scientists don't agree whether they create new species or just help maintain them.

Deciding what, exactly, constitutes a wilderness in the ocean is not completely figured out, though some researchers are trying to find an answer.
