As koalas in southern Australia have grown from a few hundred to almost half a million, the marsupials show signs of regaining lost genetic variation.

Population crashes are dangerous and can be irreversible. But new research shows they are not always an evolutionary dead end.

Koalas’ population comeback may be doing more than boosting numbers—it could also be rebuilding their lost genetic diversity.

A new study published in Science is challenging long-held assumptions about how we measure genetic risk in endangered species. Researchers analyzed whole genomes from hundreds of koalas, finding that ...

The study of genetic variation and growth traits in tree species is crucial for understanding the mechanisms that underpin forest productivity, resilience and adaptation. Recent advances in molecular ...

The human genome is organised in 46 chromosomes, where all but the x and y chromosomes in men are present in two copies. This means that a person with a faulty gene on one chromosome most often has a ...

A study expands the list of known genes with circadian variation and provides the first comprehensive list of genes with seasonal variation in each tissue. Tissues in the thoracic cavity, such as the ...

Structural variants (SVs) are alterations in the DNA sequence that involve large-scale changes, typically longer than 50 base pairs. Advances in long-read sequencing have significantly increased ...

Are human beings as unique as snowflakes? Not quite, but new research shows humans may have a lot more individuality than originally thought -- in fact, the genetic codes of people can vary by as much ...
