Year in review: Life’s complexity recoded
New genetic letters in bacteria and a simplified yeast chromosome showcase scientists' advances in understanding the simplicity and complexity of life.
- Life
First chromosome made synthetically from yeast
Work with yeast marks the first time scientists have synthesized a chromosome from organisms with complex cells and represents a major step toward lab-created eukaryotic life.

Alga borrows genes to beat the heat, acid and toxic metals
Such genetic theft from bacteria and archaea is unusual among eukaryotes.
- Microbes
The vast virome
When it comes to the microbiome, bacteria get all the press. But virologists are starting to realize that their subjects also do a lot more than make people sick.

African fossils suggest complex life arose early
Researchers find evidence that Earth’s earliest multicellular life got going 2.1 billion years ago.
- Life
All present-day life arose from a single ancestor
A major tenet of evolutionary theory — that all life stems from a common source — passes a statistical test.
