Microbial and hydrothermal aspects of ferric oxyhydroxides and ferrosic hydroxides: the example of Franklin Seamount, Western Woodlark Basin, Papua New Guinea
This paper presents mineralogical, chemical and morphological information on the oxyhydroxides from Franklin Seamount...

The effect of adsorbed lipid on pyrite oxidation under biotic conditions
This investigation reports on the growth of this bacterial species on the pyrite surface and in the aqueous phase at a pH close to 2 as well as the role of adsorbed lipid in preventing pyrite dissolution.

Influence of ancient glacial periods on the Andean fauna: the case of the pampas cat (Leopardus colocolo)
In this study, the genetic structure of the pampas cat (Leopardus colocolo), a widely distributed felid, was determined and linked to ancient climate fluctuations on the Andean region.

Deep Sea Algae Connect Ancient Climate, Carbon Dioxide And Vegetation
Assistant Professor Mark Pagani in the Department of Geology and Geophysics at Yale and his colleagues mapped the first detailed history of atmospheric carbon dioxide between 45 - 25 million years ago based on stable isotopes of carbon...

Carbon Dioxide Helped Ancient Earth Escape Deathly Deep Freeze
The planet’s present day greenhouse scourge, carbon dioxide, may have played a vital role in helping ancient Earth to escape from complete glaciation

Cleaning The Atmosphere Of Carbon: African Forests Out Of Balance
Tropical forests hold more living biomass than any other terrestrial ecosystem.

Atmosphere Threatened By Nitrogen Pollutants Entering Ocean
A large quantity of nitrogen compounds -- emitted into the atmosphere by humans through the burning of fossil fuels and the use of nitrogen fertilizers -- enters the oceans and may lead to the removal of some carbon dioxide from the atmosphere...

Tropical Rainforest Nutrients Linked To Global Carbon Dioxide Levels
Extra amounts of key nutrients in tropical rain forest soils cause them to release more carbon dioxide into the atmosphere, according to research conducted by scientists at the University of Colorado (CU) - Boulder.

How Humans Have Disrupted The Nitrogen Cycle
More and more, scientists are getting a better grip on the nitrogen cycle.

Global Warming's Ecosystem Double Whammy
Plants and soils act like sponges for atmospheric carbon dioxide, but new research finds that one abnormally warm year can suppress the amount of carbon dioxide taken up by some grassland ecosystems for up to two years

Study casts doubt on 'Snowball Earth' theory
Remains of photosynthesizing microbes in prehistoric rocks suggest Earth was not ice-bound

Paired microbes eliminate methane using sulfur pathway
Anaerobic microbes in the Earth's oceans consume 90 percent of the methane produced by methane hydrates - methane trapped in ice - preventing large amounts of methane from reaching the atmosphere.

Tiny bubbles a storehouse of knowledge
Fluid inclusions - tiny bubbles of fluid or vapor trapped inside rock as it forms - are clues to the location of ores and even petroleum; and they are time capsules that contain insights on the power of volcanoes and hints of life in the universe.

Hot springs microbes hold key to dating sedimentary rocks, researchers say
Scientists studying microbial communities and the growth of sedimentary rock at Mammoth Hot Springs in Yellowstone National Park have made a surprising discovery about the geological record of life and the environment.

Rocks could reveal secrets of life on Earth - and Mars
A new UK project could help detect evidence for life on Mars, as well as improve our understanding of how it evolved on Earth.

Dinosaur Deaths Outsourced to India?
A series of monumental volcanic eruptions in India may have killed the dinosaurs 65 million years ago, not a meteor impact in the Gulf of Mexico.

Seismic images show dinosaur-killing meteor made bigger splash
The most detailed three-dimensional seismic images yet of the Chicxulub crater, a mostly submerged and buried impact crater on the Mexico coast, may modify a theory explaining the extinction of 70 percent of life on Earth 65 million years ago.

Mass extinction's cause: 'Sick Earth'
USC earth scientists turn up clues to explain disappearance of 90 percent of ancient species

Plant A Tree And Save The Earth?
Can planting a tree stop the sea level from rising, the ice caps from melting and hurricanes from intensifying?

Tropical Forests -- Earth's Air Conditioner
Planting and protecting trees--which trap and absorb carbon dioxide as they grow--can help to remove carbon dioxide from the atmosphere.
