Predator-Prey Interactions

Predator-Prey Interactions

Predators consume prey for energy. Predators that acquire prey and prey that avoid predation both increase their chances of survival and reproduction (i.e., fitness). Routine predator-prey interactions elicit mutual adaptations that improve predator offenses, such as claws, teeth, and speed, as well as prey defenses, including crypsis, aposematism, and mimicry. Thus, predator-prey interactions resemble an evolutionary arms race.

Chromatin Packaging

Each human somatic cell contains 6 billion base-pairs of DNA. Each base-pair is 0.34 nm long, which means that each diploid cell contains a staggering 2 meters of DNA. How is such a long DNA strand packed inside a nucleus measuring only 10 - 20 microns in diameter?
The chromatin
In combination with specialized DNA binding protein called Histones, the DNA double helix forms a compact DNA: protein complex called chromatin. The chromatin itself is further compacted into higher-order...

The Nucleosome

The Nucleosome

DNA in a human cell is almost 2m long and it is packed inside a tiny nucleus that is only a few microns in diameter. The level of compaction of DNA inside the nucleus is astonishing. It is organized into several sequentially higher levels of compaction to fit into such a tiny space. The most compact form of DNA is a chromosome that can be seen under a microscope in a dividing cell.
DNA is wound twice around a protein complex called histone core, that consist of 8 histone proteins. This complex...

Background:

Microswimmers are model systems for cell migration and artificial micromachines.
A common model is a linear three-bead swimmer with active forces generating propulsion.

Purpose of the Study:

To extend the linear microswimmer to a triangular configuration.
To explore the dynamics and control of this new microswimmer geometry.
To identify minimal parameters for arbitrary trajectory control.

Main Methods:

Analytical exploration of microswimmer dynamics.
Modeling active oscillatory forces on springs in a triangular configuration.

Main Results:

The triangular microswimmer exhibits diverse motion: straight translation, rotation, and combined translation-rotation.
Complex curved trajectories are achievable through autonomous steering.
Identified minimal operating parameters for precise trajectory control.

Conclusions:

The triangular microswimmer provides insights into natural and artificial microswimmer mechanics.
Potential applications include targeted drug delivery and autonomous underwater vehicles requiring intricate path planning.
