The past decade has revealed the diversity and ubiquity of archaea in nature, with a growing
number of studies highlighting their importance in ecology, biotechnology and even human …

Highlights•Different flagellar architectures enable different motility behaviors.•Strategies for
swimming and turning vary.•Flagella can push, pull, flick, and swing, roll, or wrap around the …

Sperm motility is crucial to reproductive success in sexually reproducing organisms.
Impaired sperm movement causes male infertility, which is increasing globally. Sperm are …

Direct interspecies electron transfer (DIET) between bacteria and methanogenic archaea
appears to be an important syntrophy in both natural and engineered methanogenic …

How can single cells without nervous systems perform complex behaviours such as
habituation, associative learning and decision making, which are considered the hallmark of …

All living cells interact dynamically with a constantly changing world. Eukaryotes, in
particular, evolved radically new ways to sense and react to their environment. These …

Archaea use a molecular machine, called the archaellum, to swim. The archaellum consists
of an ATP-powered intracellular motor that drives the rotation of an extracellular filament …

Evolution works by adaptation and exaptation. At an organismal level, exaptation and
adaptation are seen in the formation of organelles and the advent of multicellularity. At the …

Bacterial flagellar system (BFS) was the primary example of a purported 'rotary-
motor'functionality in a natural assembly. This mandates the translation of a circular motion …

Amongst the major types of archaeal filaments, several have been shown to closely
resemble bacterial homologues of the Type IV pili (T4P). Within Sulfolobales, member …
