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.

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.

Researchers investigating the origin of complex life on Earth might have just made a major breakthrough. The origin of humanity and the planet Earth is probably debated more than whether the chicken ...

Researchers investigating the origin of complex life on Earth appear to have solved a longstanding mystery at the heart of how animals, plants, and fungi evolved. To understand the conundrum, you must ...

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 ...

A study on worms led by researchers from Vanderbilt University School of Medicine in the US has uncovered a previously unknown adaptation to aging that actively remodels one of the largest and most ...

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 ...

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 ...

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 ...
