Symbiotic relationships between legumes and the bacteria that grow in their roots are critical for plant survival. Without those bacteria, the plants would have no source of nitrogen, an element that is essential for building ...

Fuel cells in bacteria

The exchange of nitrogen between the atmosphere and organic matter is crucial for life on Earth because nitrogen is a major component of essential molecules such as proteins and DNA. One major route for this exchange, discovered ...

Blood molecule key to more efficient batteries

A molecule that transports oxygen in blood could be key to developing the next generation of batteries, and in a way that's environmentally friendly.

Heme channel found

In some ways a cell in your body or an organelle in that cell is like an ancient walled town. Life inside either depends critically on the intelligence of the gatekeepers.

Blood breakdown product commandeers important enzyme

The hemoglobin in the red blood cells ensures that our body cells receive sufficient oxygen. When the blood pigment is broken down, heme is produced, which in turn can influence the protein cocktail in the blood. Researchers ...
