Researchers have found statistically significant links between a gene tied to schizophrenia risk and poorer cognitive performance in a large population sample, adding new evidence that genetic ...

A large-scale genomic study of koalas across eastern Australia has found that populations that went through severe ...

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 ...

Genetic variation in livestock is a critical area of research that underpins modern breeding practices and agricultural productivity. Differences in DNA sequences, including single nucleotide ...

Researchers have demonstrated a specific type of genetic variation in obsessive-compulsive disorder (OCD) for the first time using advanced DNA sequencing technology. The findings support previous ...

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 ...

Knowing how human DNA changes over generations is essential to estimating genetic disease risks and understanding how we evolved. But some of the most changeable regions of our DNA have been ...

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

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 ...

Some koalas may recover their genes after major population crashes. Growing koala populations may rebuild genetic strength over time.

If you follow media coverage of koalas, you could be forgiven for feeling confused. Recent stories describe a “koala paradox” ...
