The beauty of the DNA code is that organisms interpret it unambiguously. Each three-letter nucleotide sequence, or codon, in a gene codes for a unique amino acid that’s added to a chain of amino acids ...

Scientists filmed ancient relatives of complex cells crawling across surfaces, revealing how movement may have evolved ...

Ten years ago, nobody knew that Asgard archaea even existed. In 2015, however, researchers examining deep-sea sediments discovered gene fragments that indicated a new and previously undiscovered form ...

Originally discovered in extreme environments such as hydrothermal vents, archaea, a single-celled microorganism, can also be found in the digestive systems of animals, including humans in which they ...

The results provide insight into the behavior of Asgard archaea and may offer clues to how complex life arose. Current models suggest that the first eukaryotes emerged around 2 billion years ago from ...

The previous installment of The Mitochondria Compendium received a great response.The three parts covered so far have dealt ...

An artist’s depiction of an Asgard archaeon, based on cryo-electron tomography data: the cell body and appendages feature thread-like skeletal structures, similar to those found in complex cells with ...

Issue No. 6Your body, as well as the grass on the roadside, is made of tiny "cells." So, how did complex cells come to be? We ...

Two archaeal strains that belong to a lineage closely related to the ancestor of eukaryotic cells (complex cells with membrane-bound organelles) have been brought into culture. Their simple internal ...

A first look into the molecular defenses of archaea highlights the importance of surveying diverse microbes to discover new types of antimicrobials As bacteria become increasingly resistant to ...
