Which is more efficient at harvesting the sun's energy, plants or solar cells? This salient question and an answer are the subject of an article published in the May 13 issue of the journal Science.Although both photosynthesis and photovoltaics harvest energy from the sun, they operate in distinctly different ways producing different fuels. It is not a simple task to find common ground between the two in order to compare energy conversion efficiency."In order to make meaningful...

New findings from UC Riverside-led team alter traditional ideas about ancient ocean chemistryGeologists at the University of California, Riverside have found chemical evidence in 2.6-billion-year-old rocks that indicates that Earth's ancient oceans were oxygen-free and, surprisingly, contained abundant hydrogen sulfide in some areas."We are the first to show that ample hydrogen sulfide in the ocean was possible this early in Earth's history," said Timothy Lyons, a professor of...

Persistent lack of oxygen in Earth's oceans affected animal evolutionThe oceans became oxygen-rich as they are today about 600 million years ago, during Earth's Late Ediacaran Period. Before that, most scientists believed until recently, the ancient oceans were relatively oxygen-poor for the preceding four billion years.Now biogeochemists at the University of California-Riverside (UCR) have found evidence that the oceans went back to being "anoxic," or oxygen-poor, around 499...

Crucial step toward turning water into hydrogen fuelA team of MIT researchers has found a novel way to mimic the process by which plants use the power of sunlight to split water and make chemical fuel to power their growth. In this case, the team used a modified virus as a kind of biological scaffold that can assemble the nanoscale components needed to split a water molecule into hydrogen and oxygen atoms.Splitting water is one way to solve the basic problem of solar energy: It's only...

The molecular secrets of a bacterium which produces its own oxygen to use the green house gas methane was unraveledA Dutch research team from the University of Nijmegen discovered bacteria that oxidize the methane without oxygen. Instead, these bacteria used nitrite, commonly available in freshwater sediments in agricultural areas. Methane is a very stable molecule and its degradation was generally believed to be impossible without oxygen (or sulfate). Now an international team from the The...

Even low concentrations of oxygen can have profound effects on ocean chemistryScientists 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...

A UC Riverside-led study reports on the effects of biological oxygen production nearly 100 million years before oxygen accumulated in the atmosphereScientists 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...
