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...
HOUSTON, May 29, 2012 /PRNewswire/ -- The International Fuel Quality Center (IFQC) has ranked the Top 100 countries based on sulfur limits in on-road diesel and found that 44 countries can now boast that their on-road diesel fuel is the cleanest in the world. "Sulfur reduction remains essential and unique, as it is the only component of the refining process for petroleum fuels that lowers all airborne pollutants from the transport sector. This is why there is added pressure and a...
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 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 fossil...
In the continual quest for better thermoelectric materials—which convert heat into electricity and vice versa—researchers have identified a liquid-like compound whose properties give it the potential to be even more efficient than traditional thermoelectrics. Thermoelectric materials have been used to power spacecraft ranging from Apollo to the Curiosity rover now headed for Mars. Recently, however, scientists and engineers have been turning to these materials to use wasted...
Spanish and Danish researchers have developed a method for the in vivo study of the unknown metabolism of selenium, an essential element for living beings. The technique can help clarify whether or not it possesses the anti-tumor properties that have been attributed to it and yet have not been verified through clinical trials. "It is vox populi that doctors around the world recommend selenium supplements to complement traditional therapy against cancer and the AIDS virus but the truth is...
University of Illinois research reports that swine producers can feed distiller's dried grain with solubles (DDGS) to their pigs without concern for sulfur content. "When you buy DDGS, you don't have to be concerned about the level of sulfur it contains because there doesn't appear to be any impact on pig performance," said U of I animal sciences professor Hans Stein. According to the researcher, DDGS, a co-product of the ethanol industry, is used as a feed ingredient in diets fed to...
