Latest Hydrogen sulfide Stories

University of Oxford Tiny 1,900 million-year-old fossils from rocks around Lake Superior, Canada, give the first ever snapshot of organisms eating each other and suggest what the ancient Earth would have smelled like. The fossils, preserved in Gunflint chert, capture ancient microbes in the act of feasting on a cyanobacterium-like fossil called Gunflintia – with the perforated sheaths of Gunflintia being the discarded leftovers of this early meal. A team, led by Dr David Wacey of...

Brett Smith for redOrbit.com – Your Universe Online Hydrogen sulfide, known to many as ‘sewer gas,’ is a deadly substance that many evolutionary biologists blame for several mass extinction events throughout Earth’s history. However, according to a new study in the open access journal PLOS ONE, very low doses of the pungent compound spur plant growth. The study’s lead researcher Frank Dooley, a University of Washington doctoral student, said he stumbled upon the beneficial...

Doctors Health Press, a division of Lombardi Publishing Corporation, and publisher of various natural health newsletters, books, and reports, including the popular online Doctors Health Press e-Bulletin, is reporting on a new study, published in Molecular and Cellular Biology, finding that hydrogen sulfide can offer a wide scope of anti-aging benefits. Boston, MA (PRWEB) February 10, 2013 Doctors Health Press, a division of Lombardi Publishing Corporation, and publisher of various natural...

Max-Planck-Gesellschaft Trees do not grow in the deep sea, nevertheless sunken pieces of wood can develop into oases for deep-sea life - at least temporarily until the wood is fully degraded. A team of Max Planck researchers from Germany now showed how sunken wood can develop into attractive habitats for a variety of microorganisms and invertebrates. By using underwater robot technology, they confirmed their hypothesis that animals from hot and cold seeps would be attracted to the wood due...

University of Illinois University of Illinois researchers developed mats of metal oxide nanofibers that scrub sulfur from petroleum-based fuels much more effectively than traditional materials. Such efficiency could lower costs and improve performance for fuel-based catalysis, advanced energy applications and toxic gas removal. Co-led by Mark Shannon, a professor of mechanical science and engineering at the U. of I. until his death this fall, and chemistry professor Prashant Jain, the...

Max-Planck-Gesellschaft Researchers uncover how microorganisms on the ocean floor protect the atmosphere against methane Microbiologists and geochemists from the Max Planck Institute for Marine Microbiology, along with their colleagues from Vienna and Mainz, show that marine methane oxidation coupled to sulfate respiration can be performed by a single microorganism, a member of the ancient kingdom of the Archaea, and does not need to be carried out in collaboration with a bacterium, as...

Multicellular bacteria transmit electrons across relatively enormous distances A multinational research team has discovered filamentous bacteria that function as living power cables in order to transmit electrons thousands of cell lengths away. The Desulfobulbus bacterial cells, which are only a few thousandths of a millimeter long each, are so tiny that they are invisible to the naked eye. And yet, under the right circumstances, they form a multicellular filament that can transmit...

Japanese scientists have recently discovered that hydrogen sulfide (H2S) – the chemical responsible for such malodorous phenomena as human flatulence, bad breath and rotten eggs – can be used to efficiently convert stem cells from human teeth into liver cells. While the fetid chemical compound is produced in small quantities by the human body for use in a variety of biological signaling mechanisms, at high concentrations it is highly poisonous and extremely flammable. A team of...

Discovery is designed to allow inexpensive detection of poisonous industrial gases by workers wearing small sensor chips filled with gold nanowires Researchers at the University of Pittsburgh have coaxed gold into nanowires as a way of creating an inexpensive material for detecting poisonous gases found in natural gas. Along with colleagues at the National Energy Technology Laboratory (NETL), Alexander Star, associate professor of chemistry in Pitt's Kenneth P. Dietrich School of Arts and...

Scientists at The City College of New York Report Nitrogen Contained in Caffeine Enhances Odor-Adsorbing Properties of Carbons For coffee lovers, the first cup of the morning is one of life’s best aromas. But did you know that the leftover grounds could eliminate one of the worst smells around – sewer gas? In research to develop a novel, eco-friendly filter to remove toxic gases from the air, scientists at The City College of New York (CCNY) found that a material made from used...
