Inhibition of movement of trition-demembranated sea-urchin sperm flagella by Mg2+, ATP4-, ADP and P1 [PDF]

open access: yes, 1979
Three clinical patterns of inhibition of MgATP2--activated flagellar motility have been found by measuring the motility of Triton-demembranated sea-urchin spermatozoa beating with their heads attached to a glass surface.

Adaptive locomotion of artificial microswimmers

open access: yes, 2019
Bacteria can exploit mechanics to display remarkable plasticity in response to locally changing physical and chemical conditions. Compliant structures play a striking role in their taxis behavior, specifically for navigation inside complex and structured

Animal emergence during Snowball Earths by thermosynthesis in submarine hydrothermal vents [PDF]

open access: yes, 2009
Darwin already commented on the lateness in the fossil record of the emergence of the animals, calling it a valid argument against his theory of evolution^1^.

Gene clusters reflecting macrodomain structure respond to nucleoid perturbations

open access: yes, 2010
Focusing on the DNA-bridging nucleoid proteins Fis and H-NS, and integrating several independent experimental and bioinformatic data sources, we investigate the links between chromosomal spatial organization and global transcriptional regulation.

\u3cem\u3eChlamydomonas\u3c/em\u3e mutants display reversible deficiencies in flagellar beating and axonemal assembly [PDF]

open access: yes, 2010
Axonemal complexes in flagella are largely prepackaged in the cell body. As such, one mutation often results in the absence of the co-assembled components and permanent motility deficiencies.

Olfaction in mosquitoes [PDF]

open access: yes, 2007
Female mosquitoes are vectors of diseases, affecting both livestock and humans. The host-seeking and identification behaviors of mosquitoes are mediated mainly by olfactory cues. The peripheral olfactory organs of mosquitoes which perceive olfactory cues
