A routine experiment with a new single-cell DNA sequencing method turned into a surprising scientific twist when researchers ...

From the first unzip of the double helix to the final joining of DNA fragments, replication is a carefully coordinated process. Understanding it helps explain how life preserves its genetic code with ...

DNA replication is one of life’s most precise and essential processes, ensuring genetic information is faithfully passed from cell to cell and generation to generation. This remarkable molecular ...

In biology you must have come across the two types of cells, the prokaryotic and eukaryotic cells. These two are the most fundamental forms of life on earth. Everything living from the bacteria on ...

"If it ain't broke, don't fix it," goes the old adage, which Rice University professor James Chappell completely ignored in a recent Nature Communications publication. In the study, Chappell describes ...

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, ...

The world of science has been stuck in an existential crisis over whether we actually know the things we thought we knew. Re-running an old study today doesn't always yield the same result. Same with ...

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 many submerged regions, murky mud shelters strange life-forms that seem to be the key to one of the biggest mysteries of life on Earth. These creatures belong to a domain of life called the archaea ...
