NASA Scientists Find Primordial Organic Matter In Meteorite
NASA researchers at Johnson Space Center, Houston have found organic materials that formed in the most distant reaches of the early Solar System preserved in a unique meteorite.

Study: Temperate Forests Could Worsen Global Warming
Growing a forest might sound like a good idea to combat global warming, since trees draw carbon dioxide from the air and release cool water from their leaves.

Scientists Find Clue To Blindness In Cavefish
In dark pools in Mexican caves, the blind cavefish survives just fine without eyesight, finding food in an environment of low productivity, swimming without bumping into the sides of the rock walls.

NASA Unveils New "Natural Hazards" Web Site
NASA has unveiled a new Web site in which it publishes satellite images in near real time over natural hazards around the world.

How Bacteria Appear To Affect Arsenic Concentrations In Groundwater
To see if bacteria affect arsenic concentration, groundwater samples were taken from two high-arsenic areas in Maine, and water chemistry and two bacterial populations were measured

Equatorial Water May Have Provided Means Of Survival
Sudden warming trends melted ice, providing refuge for multi-celled animals while the rest of the Earth was frozen

Melting The Snowball Earth
Scientists believe that during the Neoproterozoic era 750 million years ago, a severe ice age occurred that almost completely froze Earth's oceans.

Solving Darwin's Dilemma: Oxygen May Be The Clue To First Appearance Of Large Animals
New findings reported today shed light on why, after three billion years of mostly single-celled evolution, these large animals suddenly appeared in the fossil record.

150 Million-Year-Old Sunken Slab Beneath Siberia
Scientists have located a piece of Earth's ancient history buried 1,550 miles below its surface.

Study Casts Doubt On 'Snowball Earth' Theory
A study that applied innovative techniques to previously unexamined rock formations has turned up strong evidence on the "Slushball Earth"side of a decades-long scientific argument.

Geobiologists Solve 'Catch-22 Problem' Concerning The Rise Of Atmospheric Oxygen
Two and a half billion years ago, the process known as photosynthesis suddenly gained the ability to release molecular oxygen into Earth's atmosphere, causing one of the largest environmental changes in the history of our planet.
