Hydrothermal vents may add ancient carbon to ocean waters

Earth's oceans play a pivotal role in the global carbon cycle. As seawater moves and mixes, it stores and transports huge amounts of carbon in the form of dissolved organic and inorganic carbon molecules. However, the various ...

Rubisco proton production can enhance carbon dioxide acquisition

Rubisco is arguably the most abundant—and most important—protein on Earth. This enzyme drives photosynthesis, the process that plants use to convert sunlight into energy to fuel crop growth and yield. Rubisco's role is ...

Researchers trace path of light in photosynthesis

Three billion years ago, light first zipped through chlorophyll within tiny reaction centers, the first step plants and photosynthetic bacteria take to convert light into food.

Changing carbohydrates into lipids for microalgae biofuels

A cross-institutional collaboration has developed a technique to repartition carbon resources from carbohydrates to lipids in microalgae. It is hoped that this method can be applied to biofuel production. This discovery was ...

How 'great' was the great oxygenation event?

Around 2.5 billion years ago, our planet experienced what was possibly the greatest change in its history: According to the geological record, molecular oxygen suddenly went from nonexistent to becoming freely available everywhere. ...
