The "mineral-breathing" bacteria found in many oxygen-free environments may be "carbon-breathing" as well. Oxygen-free, or anaerobic, environments contain microbes sometimes described as "mineral-breathing" because they use iron oxides and other minerals in the same way we use oxygen. According to a study published online May 23 in the journal Nature Geoscience, this bacterial respiration may be accelerated by solid organic compounds in the soil. Led by University of Wisconsin-Madison...

The evolution of complex life forms may have gotten a jump start billions of years ago, when geologic events operating over millions of years caused large quantities of phosphorus to wash into the oceans. According to this model, proposed in a new paper by Dominic Papineau of the Carnegie Institution for Science, the higher levels of phosphorus would have caused vast algal blooms, pumping extra oxygen into the environment which allowed larger, more complex types of organisms to thrive....

A new form of platinum that could be used to make cheaper, more efficient fuel cells has been created by researchers at the Department of Energy's SLAC National Accelerator Laboratory and the University of Houston. The process, described in the April 25th issue of Nature Chemistry, could help enable broader use of the devices, which produce emissions-free energy using hydrogen. "This is a significant advance," said scientist Anders Nilsson, who conducts research at the Stanford Institute for...

Montana State University chemists have determined the structure of an intermediate form of a unique enzyme that participates in some of the most fundamental reactions in biology. The discovery could lead to understanding life in ancient ecosystems. It could also play a role in producing alternate fuels and fighting pollution, according to MSU researchers who published their findings April 25 in the advance online publication of the journal Nature. Lead author David Mulder, a doctoral student...

Dust may be a nuisance around the house but it plays a vital role in the formation of the key ingredient for life on Earth "“ water "“ according to researchers at Heriot-Watt University.  The results from pioneering experiments to solve one of the mysteries of the interstellar space, where did all the water come from, will be presented by Victoria Frankland at the RAS National Astronomy Meeting in Glasgow on Wednesday April 14th. "We think that the Earth's water was delivered...

Crucial step toward turning water into hydrogen fuel A team of MIT researchers has found a novel way to mimic the process by which plants use the power of sunlight to split water and make chemical fuel to power their growth. In this case, the team used a modified virus as a kind of biological scaffold that can assemble the nanoscale components needed to split a water molecule into hydrogen and oxygen atoms. Splitting water is one way to solve the basic problem of solar energy: It's only...

Research by astrobiologist William Bains suggests that if life has evolved on the frozen surface of Saturn's moon, Titan, it would be strange, smelly and explosive compared to life on Earth. Dr Bains will present his work at the National Astronomy Meeting in Glasgow on Tuesday April 13th. "Hollywood would have problems with these aliens" says Dr. Bains. "Beam one onto the Starship Enterprise and it would boil and then burst into flames, and the fumes would kill everyone in range. Even a tiny...

The role of selenium in diabetes has been controversial, with some studies suggesting that it raises diabetes risk and others finding that it is protective. Now, research published in BioMed Central's open access journal Nutrition and Metabolism, has shown that, for men, high plasma selenium concentrations are associated with a lower occurrence of dysglycemia. Tasnime Akbaraly, from the University of Montpellier, worked with a team of researchers to follow 1162 healthy French men and women...

Stratified marine basin sheds new light on early animal evolution, UC Riverside scientists say A research team led by biogeochemists at the University of California, Riverside has developed a detailed and dynamic three-dimensional model of Earth's early ocean chemistry that can significantly advance our understanding of how early animal life evolved on the planet. Working on rock samples from the Doushantuo Formation of South China, one of the oldest fossil beds and long viewed by...

Acid Rain
2013-04-01 10:21:17

Acid rain is any form of precipitation that is unusually acidic, meaning that is possesses high levels of hydrogen ions. It can have harmful effects on aquatic animals, plants, and infrastructure. Acid rain is caused by emissions of sulfur dioxide and nitrogen oxide, which react with the water molecules within the atmosphere to produce acids. Nitrogen oxides can be produced naturally by lightening strikes. Sulfur dioxide can be produced naturally by volcanic eruptions. The chemicals that are...
