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

In addition to the nucleus, eukaryotic cells may contain several other types of organelles, which may include mitochondria, chloroplasts, the endoplasmic reticulum, the Golgi apparatus, and lysosomes.

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

In a new study, published in Cell, researchers describe a newfound mechanism for creating proteins in a giant DNA virus, comparable to a mechanism in eukaryotic cells. The finding challenges the dogma ...

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.

This study provides novel insights into the elongation dynamics of eukaryotic cells and the counteracting mechanisms in place to reduce translation defects during protein synthesis. "Understanding the ...

Mouse embryonic stem cells differentiated into motor neurons after a GFP tag was inserted in frame with the motor-neuron-specific transcription factor HB9, using CRISPR/Cas9 engineering. The Patent ...

For billions of years after the origin of life, the only living things on Earth were tiny, primitive cells resembling today’s bacteria. But then, more than 1.5 billion years ago, something remarkable ...

Since the bacterial-origin CRISPR-Cas system rose to popularity as a genome editing tool, scientists have wondered whether other genome editors exist in nature. Now, two independent research teams ...

Genetics tools have advanced significantly in recent decades, and have allowed scientist to sequence all of the genetic ...

A new study challenges a popular scenario put forward to explain the arrival of the first eukaryotic organisms. In the beginning, there was boredom. Following the emergence of cellular life on earth, ...
