Around 1.7 billion years ago, eukaryotes—the building blocks of complex life—first appeared on Earth, and now scientists have ...

The most widely accepted scientific explanation for the arrival of all complex life on Earth has had an unsolved mystery at its heart. According to the theory, all plants, animals and fungi, known ...

Late in 2025, we covered the development of an AI system called Evo that was trained on massive numbers of bacterial genomes. So many that, when prompted with sequences from a cluster of related genes ...

The newly described archaeon Sukunaarchaeum mirabile carries the smallest known genome among Archaea and blurs life’s limits.

For decades, scientists have believed that complex life began when two very different microbes joined forces, eventually giving rise to plants, animals, and fungi. But one major puzzle remained: how ...

Scientists have developed Evo 2, a powerful AI model that can analyze and generate DNA sequences across all domains of life.

The origin of the nucleus remains hotly debated among scientists, but new imaging and genomic data are shedding light on this billion-year-old mystery.

A new study suggests that ancient microbes once cast as oxygen haters may have actually learned to use the gas, offering a clue to how the first complex cells — and, eventually, all plants and animals ...

By Hugo Francisco de Souza Trained on genomic data spanning the tree of life, Evo 2 reveals how artificial intelligence can ...
