A major study on the once critically endangered pink pigeon says a high load of bad genetic mutations puts it at considerable risk of extinction in the wild within 100 years without continued conservation actions.

Using a molecular probe capable of deep-tissue imaging, researchers have discovered that a high-fat diet is linked to nitric oxide levels and an increase in nitric oxide can exacerbate the development of cancer.

Scientists reveal how commensal fungi establish a symbiotic relationship that provides them a home while protecting most people from severe infections.

A new role for the fragile X protein has been identified in a new study that shows the protein can regulate a receptor in the memory center of the brain, influencing learning.

Researchers have discovered how Type I interferon stops the immune system from "going rogue" and attacking the body’s own tissues when fighting viral infections.

A new method has been developed that enables analysis of the spatial patterns of gene expression in three dimensions, permitting greater understanding of how a cell's environment can impact gene expression.

The mechanism by which the vaccinia virus repairs its DNA has been revealed – it is able to use its DNA polymerase as a multifunctional tool.

Researchers showed that inflammatory reactions of an important sensor protein proceed in a specific spatial direction, potentially enabling them to stop inflammation at the "growing end", and thus bring chronic inflammatory diseases to a halt.

A 3D organoid model of the cervix has been created, opening up opportunities for researchers to study cervical infections and cancer development more easily.

Following a heart attack, the human body is incapable of repairing lost tissue due to the heart’s inability to generate new muscle. However, treatment with heart progenitor cells could result in the formation of functional heart cells at injured sites. This new therapeutic approach is introduced by an international team in Nature Cell Biology.
