Scientists identify a plant molecule that sops up iron-rich heme

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 ...

Unraveling the initial molecular events of respiration

Respiration is a fundamental process of all living things, allowing them to produce energy, stay healthy, and survive. In cells, respiration involves what are known as "respiratory proteins," e.g. hemoglobin in the blood ...

Taming electrons with bacteria parts

Electrons are tough to pin down in biology. Learning how to harness electrons is no fool's errand because, when electrons move, they are the electricity that powers life.

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.
