Microbes Produced Oxygen Well Before Great Oxidation Event
2012-09-25 06:15:10

Brett Smith for redOrbit.com - Your Universe Online Life on earth began in the oceans, but it would eventually spread to land and a new study suggests that land-dwelling bacteria could have covered large swaths of territory about 2.7 billion years ago, despite a thin ozone layer that would have offered little protection against the sun´s ultraviolet radiation. According to astrobiologists at the University of Washington, these earliest microbes produced oxygen and broke down...

The study of an oxygen-sensing bacterial regulatory protein by chemistry researchers at the University of Georgia has provided molecular insight into the oxygen sensing mechanism, which could ultimately lead to a better understanding of the ageing process and new treatments for human diseases such cancer, Parkinson's and Alzheimer's. Michael Johnson, a distinguished research professor of chemistry in the UGA Franklin College of Arts and Sciences, and Bo Zhang, a UGA chemistry doctoral...

Rice University physicists find reversible way to alter VO2“²s unique electronic about-face If you are not a condensed matter physicist, vanadium oxide (VO2) may be the coolest material you´ve never heard of. It´s a metal. It´s an insulator. It´s a window coating and an optical switch. And thanks to a new study by physicists at Rice University, scientists have a new way to reversibly alter VO2“²s electronic properties by treating it with one of the...

New Study May Hold Clue To Proving the Gaia Theory
2012-05-18 04:30:16

The Gaia Hypothesis proposes that the Earth is actually a giant living organism, and a University of Maryland (UMD) study might have found the key to unlocking this mystery, and this discovery could lead to an improved understanding of the climate and changes that occur within it. The key is sulfur, and researchers hope to find the relationships between the atmosphere, ocean organisms, and land, using sulfur in order to prove the Gaia Theory. The Gaia Theory was first introduced in the...

Sulphur And Iron Commonly Found In Old Shipwrecks
2012-05-16 08:47:46

Sulphur and iron compounds have been found in shipwrecks off the coast of Sweden and in the Baltic Sea, according to a new study. The group behind the results includes scientists from the University of Gothenburg and Stockholm University. The results were presented recently in the Journal of Archaeological Science. Scientists reported large quantities of sulphur and iron compounds in the salvaged 17th century warship Vasa a few years ago. This resulted in the development of sulphuric acid...

It may seem counterintuitive, but one way to reduce carbon dioxide emissions to the atmosphere may be to produce pure carbon dioxide in powerplants that burn fossil fuels. In this way, greenhouse gases – once isolated within a plant – could be captured and stored in natural reservoirs, deep in Earth's crust. Such "carbon-capture" technology may significantly reduce greenhouse gas emissions from cheap and plentiful energy sources such as coal and natural gas, and help minimize...

A detailed description of development of the first practical artificial leaf – a milestone in the drive for sustainable energy that mimics the process, photosynthesis, that green plants use to convert water and sunlight into energy – appears in the ACS journal Accounts of Chemical Research. The article notes that unlike earlier devices, which used costly ingredients, the new device is made from inexpensive materials and employs low-cost engineering and manufacturing processes....

How hydrogen--the most abundant element in the cosmos--responds to extremes of pressure and temperature is one of the major challenges in modern physical science. Moreover, knowledge gleaned from experiments using hydrogen as a testing ground on the nature of chemical bonding can fundamentally expand our understanding of matter. New work from Carnegie scientists has enabled researchers to examine hydrogen under pressures never before possible. Their work is published online in Physical Review...

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...

  • Nautical, the visiting and carousing of sailors in the Greenland ships.
This word is apparently from a confusion of two similar Dutch words: 'mallemerok,' a foolish woman, and 'mallemok,' a name for some persons among the crew of a whaling vessel.
