When bacteria cells replicate, they do so a little differently than human cells do. They don't undergo mitosis, a splitting that involves construction of spindles to carefully separate the DNA after ...

Newly found giant DNA Ushikuvirus may offer clues to cell evolution
A giant DNA virus pulled from a Japanese freshwater pond is forcing scientists to rethink how complex cells first acquired their defining feature: the nucleus. Named ushikuvirus, the newly ...
By simulating the life cycle of a minimal bacterial cell — from DNA replication to protein translation to metabolism and cell division — scientists have opened a new frontier of computer vision into ...
The story of life’s beginnings gets stranger when you look closely at viruses. These tiny entities seem to sit at the edge of ...
Scientists developed Evo 2, a large biological foundation model trained on about 9 trillion DNA base pairs that can analyse ...
In the oceans and on land, scientists are discovering rare, transitional organisms that bridge the gap between Earth’s simplest cells and today’s complex ones. By Carl Zimmer A flurry of new studies ...
Breathe easy. It appears our microbial ancestors used oxygen, too. In December 2025, Brett Baker led a research cruise to collect microbial genomes off the coast of Uruguay. In this photo, Tyler Smith ...
In 1869, Swiss scientist Friedrich Miescher isolated a mysterious substance from cell nuclei—an overlooked finding that would later reshape biology and our understanding of life itself. A ...
DNA doesn’t just sit still inside our cells — it folds, loops, and rearranges in ways that shape how genes behave. Researchers have now mapped this hidden architecture in unprecedented detail, showing ...
Every human body is built from eukaryotic cells, which have a nucleus, DNA packaged into chromosomes, and internal compartments. In contrast, bacteria and archaea have simpler cells. For many years, ...
The DNA packed inside every human cell contains instructions for life, written in billions of letters of genetic code. Every time a cell divides, the complete code, divided among 46 chromosomes, must ...
