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 ...

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 ...

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.
