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.

Scientists are trying to understand how complex life emerged on Earth about 2 billion years ago. Our microbial ancestors could be the key.

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 ...

The sun has just set on a quiet mudflat in Australia’s Northern Territory; it’ll set again in another 19 hours. A young moon looms large over the desolate landscape. No animals scurry in the waning ...

This article was originally featured on Knowable Magazine. More than 1.5 billion years ago, a momentous thing happened: Two small, primitive cells became one. Perhaps more than any event—barring the ...

An international collaboration between four senior scientists from Mainz, Valencia, Madrid, and Zurich has published groundbreaking research in the journal PNAS, shedding light on the most significant ...

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 ...

How did life leap from simple microbial cells to the complex, structured cells that make up animals, plants, and fungi? A new study in The EMBO Journal by researchers at the Indian Institute of ...

The story of life’s beginnings gets stranger when you look closely at viruses. These tiny entities seem to sit at the edge of biology.

Approximately four billion years ago, the first forms of life emerged on Earth. For eons, biological life consisted of prokaryotic organisms, either early bacteria or archaea. Determining when ...
