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 ...

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 ...

Scientists are uncovering the surprising ways bacteria and archaea differ — and how these differences could be turned into weapons against dangerous infections. From bacteria’s peptidoglycan walls to ...

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 ...

Following the drive to understand and control bacteria, it’s becoming clear that our methods have changed the very organisms we aim to understand, increasing resistance to tried-and-true antimicrobial ...

"Hearst Magazines and Yahoo may earn commission or revenue on some items through these links." Around four billion years ago, prokaryotes (which include the simple-cell domains of archaea and bacteria ...

Archaea, once thought to only survive in extreme environments, are now recognized as vital players in ecosystems from soil to sea. They drive key nutrient cycles, help plants grow, and even produce ...

There are few hard and fast rules in the study of life, but perhaps the closest we get is the central dogma of molecular biology: DNA is transcribed to RNA, which gets translated into proteins. The ...

At first sight, stromatolites may seem unremarkable. The stromatolite formations found in Shark Bay, Western Australia, do resemble dark, sediment-covered stones resting in shallow waters.
