Investigating Life In Extreme Environments Report Gives Hints On Facts Of Life
Environments labelled as extreme are numerous on Earth and they present a wide variety of features and characteristics.

Bacteria Grown In Simulated Martian Environment
A University of Arkansas researcher has become the first scientist to grow methane-producing microorganisms under some of the conditions found on Mars.

Life Cycle Mapped Of Unique Organism In Extreme Environments
Microorganisms that thrive under extreme conditions, such as hot acid, not only can be used as a model for how life got started on earth or can emerge on other planets but can also provide knowledge about humans.

Africa and the global carbon cycle
The African continent has a large and growing role in the global carbon cycle, with potentially important climate change implications.

Planet Earth, getting too hot for health?
Global warming — an increase in the average temperature of the planet because of human activities that are raising greenhouse gas levels in the atmosphere

Contributions of nitrogen deposition and forest regrowth to terrestrial carbon uptake
This study shows that elevated nitrogen deposition would not significantly enhance land carbon uptake unless we consider its effects on re-growing forests.

The planetary biology of cytochrome P450 aromatases
Joining a model for the molecular evolution of a protein family to the paleontological and geological records (geobiology)

Marine geochemical data assimilation in an efficient Earth System
The authors have extended the 3-D ocean based “Grid ENabled Integrated Earth system model” (GENIE-1) to help understand the role of ocean biogeochemistry and marine sediments in the long-term

Did you know? The oldest organisms live in waste repositories
Some of the oldest organisms - Archaea - live in waste repositories.

Marine scientists determine how chemistry keeps weird worms out of hot water
A research team has determined that water chemistry controls the location and distribution of two species of weird worms that inhabit deep-sea hydrothermal vent sites.

Geologist suggests water may reside as ice deep in planets' interior
Water may be transported into the interior of planets as a high-pressure form of ice...

Increasing production of economically valuable limestone through paleontological interpretation of the fossil Record.
Paleobiology: stratigraphic interpretation of the fossil record of Pleistocene south central Florida.

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.
