When antibiotics attack microbes, their stressed neighbors ship them proteins to help them survive, new work suggests.

Scientists built a synthetic cell that combines more lifelike properties than ever before — proof of concept that it’s possible to bring nonliving materials to life, or something close to it, in the ...

Thymine metabolism in prokaryotes encompasses both de novo synthesis of deoxythymidine triphosphate (dTTP) via the reductive branch of pyrimidine biosynthesis and salvage pathways that recover ...

In prokaryotes, DNA replication initiates at a single defined origin and proceeds bidirectionally via a multiprotein replisome that unwinds the duplex and synthesises new strands. Elongation is ...

Here’s what you’ll learn when you read this story: The first eukaryotes—the cells that form complex life—likely originated when two microscopic entities merged via a process called endosymbiosis, ...

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 ...

When cells proliferate, genomic DNA is precisely duplicated once per cell cycle. Abnormalities in this DNA replication process can cause alterations in genomic DNA, promoting cellular ageing, cancer, ...

The Age of AI will rely on massive volumes of data that can be easily stored and retrieved—and bioscience may have an ingenious solution. A scientist examines a DNA (deoxyribonucleic acid) profile on ...
