Rock-water reactions can produce hydrogen when temperatures are far too hot for living things to survive, such as near hydrothermal vent systems on the ocean floor. However, a new study reports that the same hydrogen-producing reaction can also occur at more hospitable temperatures, like those found on the ocean floor or even Mars.
Duke University engineers have developed a novel method for producing clean hydrogen, which could prove essential to weaning society off of fossil fuels and their environmental implications.
A research team of biogeochemists at the University of California, Riverside has provided a new view on the relationship between the earliest accumulation of oxygen in the atmosphere, arguably the most important biological event in Earth history, and its relationship to the sulfur cycle.
Software builds "library" of millions of small, carbon-based molecules chemists might synthesize.
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.
A research team at the University of Leeds may have solved the question of how objects from space could have kindled life on Earth.
An international research group led by biogeochemists at the University of California, Riverside has filled a billion-year gap in our understanding of conditions in the early ocean during a critical time in the history of life on Earth.
A new study focusing on the mineral molybdenite could provide new insight into the way that various geological and biological processes have resulted in changes to the Earth’s chemistry over the years.
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...
