SEATTLE, June 11 /PRNewswire/ -- How is it that some people who apparently freeze to death, with no heart rate or respiration for extended periods, can be brought back to life with no long-term negative health consequences? New findings from the laboratory of cell biologist Mark B. Roth, Ph.D., of Fred Hutchinson Cancer Research Center, may help explain the mechanics behind this widely documented phenomenon. Reporting online ahead of the July 1 print issue of Molecular Biology of the Cell,...

Stratified marine basin sheds new light on early animal evolution, UC Riverside scientists say A research team led by biogeochemists at the University of California, Riverside has developed a detailed and dynamic three-dimensional model of Earth's early ocean chemistry that can significantly advance our understanding of how early animal life evolved on the planet. Working on rock samples from the Doushantuo Formation of South China, one of the oldest fossil beds and long viewed by...

NEEDHAM, Mass., Nov. 24 /PRNewswire/ -- Environmental Health & Engineering Inc. (EH&E), a leading Massachusetts-based engineering consulting firm, has completed a major indoor air quality study for the U.S. government which found a strong association between the presence of Chinese drywall, low level concentrations of hydrogen sulfide, and corrosion of metals in homes. The drywall issue has affected thousands of homes in the United States for more than two years. The five-month...

A new study showed a significant link between indoor pollution in homes with drywall imported from China, leading U.S. officials to take a deeper look at the affect that the product has on health. According to the Consumer Product Safety Commission (CPSC), it will be heading up an investigation into finding the origin and distribution of the drywall as well as the connection between the drywall and the reported health symptoms, and electrical and fire safety issues that some home owners...

Even low concentrations of oxygen can have profound effects on ocean chemistry Scientists widely accept that around 2.4 billion years ago, the Earth's atmosphere underwent a dramatic change when oxygen levels rose sharply. Called the "Great Oxidation Event" (GOE), the oxygen spike marks an important milestone in Earth's history, the transformation from an oxygen-poor atmosphere to an oxygen-rich one, paving the way for complex life to develop. Two questions that remain unresolved in studies...

A UC Riverside-led study reports on the effects of biological oxygen production nearly 100 million years before oxygen accumulated in the atmosphere Scientists widely accept that around 2.4 billion years ago, the Earth's atmosphere underwent a dramatic change when oxygen levels rose sharply. Called the "Great Oxidation Event" (GOE), the oxygen spike marks an important milestone in Earth's history, the transformation from an oxygen-poor atmosphere to an oxygen-rich one paving the way for...

Garlic provides cardioprotection, but freshly crushed garlic has more potent heart-healthy effects, U.S. researchers found. Researchers at the University of Connecticut School of Medicine in Farmington also challenge the widespread belief that most of garlic's benefits are due to its rich array of antioxidants. Dipak K. Das and colleagues point out that raw, crushed garlic generates hydrogen sulfide through a chemical reaction. Although best known as the stuff that gives rotten eggs their...

A new study reports what scientists term the first scientific evidence that freshly crushed garlic has more potent heart-healthy effects than dried garlic. Scheduled for the Aug. 12 issue of the Journal of Agricultural and Food Chemistry, it also challenges the widespread belief that most of garlic's benefits are due to its rich array of antioxidants. Instead, garlic's heart-healthy effects seem to result mainly from hydrogen sulfide, a chemical signaling substance that forms after garlic is...

University of Leicester researcher probes role of hydrogen sulphide Scientists at the University of Leicester are investigating how the stuff of stink bombs and flatulence could play a critical role in the human reproductive system. Hydrogen sulphide "“partially responsible for the foul odor of stink bombs- is also a toxic gas and has been used for chemical warfare. But research at the University of Leicester is now looking at beneficial effects it has in the body- and the potentially...

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,...
