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.

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.

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 ...

Complex cells are thought to be the result of a union between two ancient microorganisms, but scientists have long been ...

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 ...

Scientists propose that eukaryotes formed when an Asgard archaeon entered into a close partnership with an alphaproteobacterium. Over time, the two organisms became permanently linked. 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 ...

Eukaryotic cells grow and divide through a specific series of cellular events. These events are tightly controlled, ensuring that the resultant daughter cells are free of DNA errors, and subject to ...

For decades, scientists have believed that complex life began when two very different microbes joined forces, eventually ...
