Behind the Scenes With the Spacecraft That Will Soar Through the Sun’s Atmosphere

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.
