Genes are made of deoxyribonucleic acid (DNA), which contains sequences of four nucleotide bases (adenine, cytosine, guanine, and thymine) that act as biological instructions for making proteins.
Life’s story may stretch further back than scientists once thought. Some genes found in nearly every organism today were already duplicated before all life shared a common ancestor. By tracking these ...
Lurking within the genomes of nearly all species--including plants, fungi, and even humans--are genes that are passed from generation to generation with no clear benefit to the organism. Called ...
Most genes are ancient and shared across species. But a small subset of genes are relative newcomers, spontaneously emerging from stretches of DNA that once encoded nothing at all. Together, the ...
An estimated 170,000 Australians were diagnosed with cancer in 2025. Many people know the causes of cancer are partly genetic. But how do your genes, which contribute so much of what makes you you, ...
De novo genes are evolution’s magic trick—new genes appearing from non-coding DNA, much like a rabbit pulled from a hat. Once considered impossible, de novo genes have been identified in Drosophila ...
Differences between men and women in intelligence and behaviour have been proposed and disputed for decades. Now, a growing body of scientific evidence shows hundreds of genes act differently in the ...
