A spike in ancient marine phosphorus concentrations from 750 to 635 million years ago is linked to emergence of complex life, UC Riverside researchers say A team of scientists, led by biogeochemists at the University of California, Riverside, has found new evidence linking "Snowball Earth" glacial events to the rise of early animals. The controversial Snowball Earth hypothesis posits that the Earth was covered from pole to pole by a thick sheet of ice lasting, on several occasions, for...

Rice researchers find metallacarboranes may meet DOE storage goals New research by Rice University scientists suggests that a class of material known as metallacarborane could store hydrogen at or better than benchmarks set by the United States Department of Energy (DOE) Hydrogen Program for 2015. The work could receive wide attention as hydrogen comes into play as a fuel of the future for cars, in fuel cells and by industry. The new study by Rice theoretical physicist Boris Yakobson and his...

Human impact is causing lower oxygen and higher carbon dioxide levels in coastal water bodies. Increased levels of carbon dioxide cause the water to become more acidic, having dramatic effects on the lifestyles of the wildlife that call these regions home. The problems are expected to worsen if steps aren't taken to reduce greenhouse emissions and minimize nutrient-rich run-off from developed areas along our coastlines. The ocean is filled with a soup of bacteria and viruses. The animals...

Call it the anti-sunscreen. That's more or less the description of what many solar energy researchers would like to find -- light-catching substances that could be added to photovoltaic materials in order to convert more of the sun's energy into carbon-free electricity. Research reported in the journal Applied Physics Letters, published by the American Institute of Physics (AIP), describes how solar power could potentially be harvested by using oxide materials that contain the element...

By swapping out one specific hydrogen atom for an isotope twice as heavy, researchers have increased the shelf life and detection ability of fluorescent probes that are essential to studying a variety of inflammatory diseases, including cancer and atherosclerosis. The probes detect and measure reactive oxygen species, which play an important role in disease processes. "By replacing a hydrogen atom with a deuterium atom during the synthesis of several fluorescent probes, we increased the...

Mice at altitude save oxygen during exercise by using more carbohydrates rather than fat, Canadian and Peruvian scientists reveal This fuel-preference represents an adaptation in high altitude mice to use oxygen more efficiently than their low-altitude counterparts. "Andean mouse species have independently evolved a strategy to maximize energy yield when little oxygen is available" explain lead researchers Marie-Pierre Schippers and Grant McClelland from McMaster University. It is very...

Hydrogen is the most abundant element in the universe and is a major component of giant planets such as Jupiter and Saturn. But not much is known about what happens to this abundant element under high-pressure conditions when it transforms from one state to another. Using quantum simulations, scientists at the Lawrence Livermore National Laboratory, the University of Illinois at Urbana-Champaign and the University of L'Aquia in Italy were able to uncover these phase transitions in the...

In a paper in Nature Chemistry, Vivek Shenoy and colleagues pinpointed noncarbon atoms that create defects when graphene is produced through a technique called graphene-oxide reduction. The researchers also propose how to make that technique more efficient by precisely applying hydrogen "“ rather than heat "“ to remove the impurities. Graphene, a carbon sheet that is one-atom thick, may be at the center of the next revolution in material science. These ultrathin sheets hold great...

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...
