Carbon dioxide emissions are fueling more verdant landscapes around the globe, but the potentially temporary greening doesn't mean global warming is good.
Cyanobacteria may use their whole body as a light-gathering apparatus, similar to a camera that helps the primitive organisms "see" and move toward light.

The Arctic's shrinking sea ice is reshaping the region's food web from the bottom up, a new study reports.
Gobs of microscopic organisms called algae may have met their match in viruses that can invade their cells, ultimately leading to death, new research suggests.
From microbes to plants and large predators, every organism on Earth has evolved unique survival mechanisms and research has shown us how this biodiversity can help society.
A new picture has emerged of the rise of oxygen on Earth. A growing body of data suggests the earliest photosynthesis evolved 600 million years before the Great Oxidation Event.
