The first great branching of the evolutionary tree, between bacteria and archaea, may have happened before either of them ...

The genetic code appeared on Earth at the origin of life, and the codes of culture arrived almost four billion years later. For a long time it has been assumed that these are the only codes that exist ...

The DNA foundation model Evo 2 has been published in the journal Nature. Trained on the DNA of over 100,000 species across the entire tree of life, Evo 2 can identify patterns in gene sequences across ...

Methane-producing archaea from the species Methanosarcina acetivorans. The microbes are stained with a fluorescent dye that specifically binds to the membranes of archaea. The beauty of the DNA code ...

The genetic building blocks of life—formed from the four nucleotides adenine (A), cytosine (C), guanine (G), and thymine (T)—are read in groups of three known as codons. While some codons (known as ...

DNA or deoxyribonucleic acid it the blueprint for all life on Earth. From the colour of your hair to the size of your nose, DNA instructs your body on how to grow, develop and produce the proteins ...

Scientists have pushed back LUCA’s origin by hundreds of millions of years.

James Dewey Watson, who died on Nov 6, was one of the most famous names in modern science. He was an American biologist best known for discovering the double-helix structure of DNA, the molecule that ...
