Why the Greatest Mass Extinction Made Modern Mammals
A new study shows that the closest ancient relatives of mammals not only survived the greatest known mass extinction in Earth's history, they also thrived in its aftermath.
Seeing Photosynthesis from Space
NASA scientists have found a new way to use satellites to measure what's occurring inside plants at a cellular level.
The Greening of Earth
A new study suggests that life on land is four times as old as previously believed. Researchers have discovered a 2.2 billion year old fossil microorganism in South Africa that could be the oldest known eukaryote.
An Infinity of Plankton
The first global atlas of marine plankton reveals remarkable underwater world.
A 'Perfect Storm' for Life
As the Earth warmed following the last Ice Age, biological productivity in the North Pacific Ocean suddenly increased, and then quickly dropped. A new study could help explain how this mysterious event occurred.
Toxic Oceans May Have Delayed Spread of Complex Life
A new model suggests that inhospitable hydrodgen-sulphide rich waters could have delayed the spread of complex life forms in ancient oceans.
How Extinction Influences Biodiversity
A new study shows that Australia's rich plant diversity was wiped out by the ice ages.
The Carbon Cycle is a War Without End
Scientists have uncovered a war in the oceans that has been going on for hundreds of millions of years. The battle is between SAR11 bacterium and the Pelagiphage viruses that infect them, and the results of this microscopic war have profound effects on Earth's carbon cycle.
Did Ancient Ecosystems Work Like Modern Ones?
A new study is helping scientists understand whether or not the relationship between animals and lush vegetation was the same in ancient ecosystems as it is today.
Do Palm Trees Hold the Key to Immortality?
A new study shows that the unique cellular structure and function of palm trees may contribute to their long life-span.
