Sperm and egg cells, or gametes, are unusual. Egg cells are some of the largest cell types, and sperm are some of the smallest. In humans, these haploid cells come together to form diploid cells. It's ...

Life is not possible without nitrogen. There are many ways for organisms to acquire nitrogen. For example, humans eat proteins for their high nitrogen content. Most microorganisms take up nitrogen ...

Scientists have been trying to learn more about archaea since these microbes were discovered in the 1970s. Their DNA is not contained in a nucleus, so they are a type of prokaryote, and were initially ...

Researchers have succeeded in cultivating a special archaeon and characterizing it more precisely using microscopic methods. This member of the Asgard archaea exhibits unique cellular characteristics ...

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 ...

Study of Asgard archaea reveals insights into the evolution of cellular complexity through analysis of cytoskeletal proteins.

The 12-year-long endeavor reveals Prometheoarchaeum as a tentacled cell, living in a symbiotic relationship with methane-producing microbes. Elusive Asgard Archaea Finally Cultured in Lab Elusive ...
