Thanks to a collaboration between scientists in San Sebastian and Japan, a relay reaction of hydrogen atoms at a single-molecule level has been observed in real-space. This way of manipulating matter could open up new ways to exchange information between novel molecular devices in future electronics. Dr. Thomas Frederiksen, presently working in the Donostia International Physics Center (DIPC) is one of the scientists that has participated in this research project. The results have been...

The appearance of oxygen in the Earth's atmosphere probably did not occur as a single event, but as a long series of starts and stops, according to an international team of researchers who investigated rock cores from the FAR DEEP project. The Fennoscandia Arctic Russia - Drilling Early Earth Project -- FAR DEEP -- took place during the summer of 2007 near Murmansk in the northwest region of Russia. The project, part of the International Continental Scientific Drilling Program,...

Much of our knowledge about past life has come from the fossil record — but how accurately does that reflect the true history and drivers of biodiversity on Earth? "It's a question that goes back a long way to the time of Darwin, who looked at the fossil record and tried to understand what it tells us about the history of life," says Shanan Peters, an assistant professor of geoscience at the University of Wisconsin—Madison. In fact, the fossil record can tell us a great...

If we could make plant food from nitrogen the way nature does, we'd have a much greener method for manufacturing fertilizer — a process that requires such high temperatures and pressures that it consumes about 1.5 percent of the world's energy. Now scientists working at the Department of Energy's SLAC National Accelerator Laboratory have taken an important step towards understanding how nature performs this trick, by identifying a key atom that researchers had sought for more than a...

Sweet Spots For The Formation Of Complex Organic Molecules In The Galaxy
2011-11-03 04:54:28

Scientists within the New York Center for Astrobiology at Rensselaer Polytechnic Institute have compiled years of research to help locate areas in outer space that have extreme potential for complex organic molecule formation. The scientists searched for methanol, a key ingredient in the synthesis of organic molecules that could lead to life. Their results have implications for determining the origins of molecules that spark life in the cosmos. The findings will be published in the Nov. 20...

Journal of Biological Chemistry: Oxygen inactivates the enzyme function in three phases Scientists from the Faculty of Biology and Biotechnology at the RUB have published a report in the Journal of Biological Chemistry explaining why enzymes used for the production of hydrogen are so sensitive to oxygen. In collaboration with researchers from Berlin, they used spectroscopic methods to investigate the time course of the processes that lead to the inactivation of the enzyme's iron center....

Law enforcement may have a new crime-solving tool, courtesy of geoscientists. About five years ago, scientists coined the word "isoscape" to describe a new kind of map: a spatial distribution of stable isotope ratios (from elements such as carbon, hydrogen, oxygen, nitrogen and strontium) in different parts of the world, based on known ways that these isotopes behave in the environment. Different isotopes tell different stories – carbon can help identify diet, whereas hydrogen and...

Image 1 - Evidence For Iron-Rich Ancient Ocean Changes View Of Earth's Early History

  Discovery challenges previous models for environment in which early life evolved Over the last half-billion years, the ocean mostly has been full of oxygen and teeming with animal life. But earlier, before animals evolved, oxygen was harder to come by. Now a new study, led by researchers at the University of California, Riverside (UCR), reveals that the ancient deep ocean was not only devoid of oxygen but also rich in iron, a key biological nutrient for nearly a billion years...

Researchers from the University of Western Australia and the University of Oxford have unearthed what they believe are the oldest fossils ever discovered-single-celled organisms that are thought to be 3.4 billion years old, according to a Sunday article by Nicholas Wade of the New York Times. The discovery, which is detailed in the latest edition of the journal Nature Geoscience, took place in a remote location known as Strelley Pool, which is located in Western Australia. The team that...

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...
