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

Our single-celled ancestor lived in a world without plants, animals or oxygen-rich oceans. Yet, this seemingly simple microorganism took the first steps toward complex life. From this ancestor emerged ...

Ancient microbes tied to our earliest ancestors could use oxygen, reshaping ideas about how complex life began on Earth.

How does a single cell reliably build one of the most complex structures known in nature? New research suggests the answer ...

A microscopic creature from a boiling hot spring in Northern California has just reset the upper limit for how hot complex life can run. The newly described “fire amoeba” thrives at temperatures that ...

The origin of many diseases begins at the cellular level and involves multiple molecular interactions. However, previous methods have struggled to accurately observe changes in individual cells.

Every second, hundreds to thousands of molecules move through thousands of nuclear pores in each of your cells. A new high-definition view reveals the machine in action.

A giant virus discovered in Japan is adding fuel to the provocative idea that viruses helped create complex life. Named ushikuvirus, it infects amoebae and shows unique traits that connect different ...

Conventional studies on stem cell fates are primarily focused on transcription factors, with the limited consideration for 3D genome architecture. The cohesin complex dynamically restructures ...
