Molecular motors are cellular nanomachines that convert the energy from nucleotide binding, hydrolysis, and product release into mechanical work. Because molecular motors contribute to fundamental processes in all living organisms, includin...

This paper extends previous work on the Darwinian evolutionary fitness effect of the fixation of deleterious mutations by incorporating compensatory mutations, which are mutations (deleterious by themselves) that ameliorate other deleteriou...

Our visual system can operate at fascinating speeds. Psychophysical experiments teach us that the processing of complex natural images and visual object recognition require a mere split second. Even in everyday life, our gaze seldom rests f...

Since the discovery of gene products oscillating during the formation of vertebral segments, much attention has been directed toward eluciating the molecular basis of the so-called segmentation clock. What research has told us is, that even...
Forward locomotion of the nematode C. elegans is achieved through modulation of a single gait [0.03%]

The ability of an animal to locomote through its environment depends crucially on the interplay between its active endogenous control and the physics of its interactions with the environment. The nematode worm Caenorhabditis elegans serves ...

Biomolecular motors have inspired the design and construction of artificial nanoscale motors and machines based on nucleic acids, small molecules, and inorganic nanostructures. However, the high degree of sophistication and efficiency of bi...

Lamellipodia are broad actin-based structures that define the protruding edge of many motile animal cells. Here we identify a Drosophila homolog of the p21-activated kinases (Paks) as a novel inhibitor of Rac-mediated lamellipodial formatio...

Sensory maps in the nervous system often connect to each other in a topographic fashion. This is most strikingly seen in the visual system, where neighboring neurons in the retina project to neighboring neurons in the target structure, such...
Highly thermosensitive Ca dynamics in a HeLa cell through IP(3) receptors [0.03%]

Intracellular Ca(2+) distribution and its dynamics are essential for various cellular functions. We show with single HeLa cells that a microscopic heat pulse induces Ca(2+) uptake into intracellular stores during heating and Ca(2+) release ...
