"Active sleep" only lasted 40 seconds but cycled after 30 to 40 minutes of "quiet sleep". These patterns are similar pattern to how mammals experience rapid eye movement (REM) sleep.

Like Humans and Mammals, Octopuses May Have Two Stages of Sleep

Scientists do not know if octopuses dream in color, but they do change color while sleeping

Damages wrought by climate change and deforestation have transformed the Amazon rainforest. New research suggests the changes to this icon of the natural world caused by human activity may mean the Amazon now emits more greenhouse gases than it absorbs.

The Amazon Rainforest Now Emits More Greenhouse Gases Than It Absorbs

Climate change and deforestation have transformed the ecosystem into a net source of planet-warming gases instead of a carbon sink

Bald eagle populations have been steadily recovering since their all-time low in the 1960s when fewer than 500 nesting pairs were left.
