Latest Hydrogen sulfide Stories
Heart rate and metabolism drop, while blood pressure and oxygen levels maintained
The greatest mass extinction in Earthâ€™s history also may have been one of the slowest, according to a study that casts further doubt on the extinction-by-meteor theory.
This summer, a science team set out on a two-week expedition of Earth's own little version of Jupiter's moon Europa -- the Borup Fiord Pass at Ellesmere Island, a place hidden high above the rest of the world in the Canadian High Arctic.
Sustained elevation of the suicide rate in a North Carolina county may be linked to releases of hydrogen sulfide and other airborne chemicals from a nearby paper mill and possibly other industrial sites, a new study led by a University of North Carolina at Chapel Hill psychiatrist indicates. The findings are being presented today (Nov. 7) to the 18th Annual U.S. Psychiatric and Mental Health Congress in Las Vegas.
NASA exobiology researchers confirmed Earth's oceans were once rich in sulfides that would prevent advanced life forms, such as fish and mammals, from thriving. The research was funded in part by NASA's exobiology program
Scientists at Fred Hutchinson Cancer Research Center have, for the first time, induced a state of reversible metabolic hibernation in mice. This achievement, the first demonstration of "hibernation on demand" in a mammal, ultimately could lead to new ways to treat cancer and prevent injury and death from insufficient blood supply to organs and tissues.
If you've tried mints, mouthwash and toothpaste but your breath still offends, maybe you should skip the oral hygiene aisle. Next time, try the dairy case. In a small study, Japanese researchers have found that eating traditional, sugarless yogurt reduces the malodorous compounds that cause bad breath.
Volcanic eruptions in Siberia 251 million years ago may have started a cascade of events leading to high hydrogen sulfide levels in the oceans and atmosphere and precipitating the largest mass extinction in Earth's history, according to a Penn State geoscientist.
Sulfur (or Sulphur; see spelling below) is the chemical element in the periodic table that has the symbol S and atomic number 16. It is an abundant, tasteless, odorless, multivalent non-metal. Sulfur, in its native form, is a yellow crystaline solid. In nature, it can be found as the pure element or as sulfide and sulfate minerals. It is an essential element for life and is found in several amino acids. Its commercial uses are primarily in fertilizers but it is also widely used in gunpowder,...
- The act of burning, scorching, or heating to dryness; the state or being thus heated or dried.
