Summary
This study introduces a new information theory-based method to quantify biological symmetry. This approach accurately measures dynamic symmetries in living organisms and patterns, offering a rigorous and efficient tool for scientific analysis.
Area of Science:
- * Biological Sciences
- * Mathematical Biology
- * Developmental Biology
Background:
- * Symmetry is a fundamental property of life, observed across all organisms.
- * Quantifying biological symmetry is challenging due to its dynamic and transient nature.
- * Existing mathematical and physical measures often fail to capture biological complexities.
Purpose of the Study:
- * To develop a novel, information theory-based measure for quantifying biological symmetry.
- * To enable the identification and measurement of approximate symmetries in biological systems.
- * To provide a rigorous and unbiased method for symmetry analysis.
Main Methods:
- * Application of information theory concepts to develop a new symmetry quantification measure.
- * Testing the measure on patterns from Turing models and natural objects (algae, flowers, leaves).
- * Evaluation of rotation, reflection, and translation symmetries.
Main Results:
- * The novel measure successfully quantifies degrees of symmetry in diverse biological patterns.
- * The method is unbiased, rigorous, and requires minimal manual processing.
- * Demonstrated applicability to both model-generated patterns and natural specimens.
Conclusions:
- * The proposed method offers a robust tool for comparing and identifying symmetries in biological systems.
- * Potential applications include analyzing developmental processes and patterns from mathematical models.
- * Facilitates a deeper understanding of symmetry in morphogenesis and biological organization.

Gastrulation
61.0K
Gastrulation establishes the three primary tissues of an embryo: the ectoderm, mesoderm, and endoderm. This developmental process relies on a series of intricate cellular movements, which in humans transforms a flat, “bilaminar disc” composed of two cell sheets into a three-tiered structure. In the resulting embryo, the endoderm serves as the bottom layer, and stacked directly above it is the intermediate mesoderm, and then the uppermost ectoderm. Respectively, these tissue strata...

Sutures of the Skull
8.4K
The human skull is composed of several bones that come together to protect the brain and support the structures of the face. The junctions where these bones meet are called sutures.
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...

Determination
19.6K
During embryogenesis, cells become progressively committed to different fates through a two-step process: specification followed by determination. Specification is demonstrated by removing a segment of an early embryo, “neutrally” culturing the tissue in vitro—for example, in a petri dish with simple medium—and then observing the derivatives. If the cultured region gives rise to cell types that it would normally generate in the embryo, this means that it is specified. In...

Synteny and Evolution
3.4K
John H. Renwick first coined the term “synteny” in 1971, which refers to the genes present on the same chromosomes, even if they are not genetically linked. The species with common ancestry tend to show conserved syntenic regions. Therefore, the concept of synteny is nowadays used to describe the evolutionary relationship between species.
Around 80 million years ago, the human and mice lineages diverged from the common ancestor. During the course of evolution, the ancestral...

Determining the Plane of Cell Division
3.5K
Positioning the cell division plane is a critical step during development and cell differentiation, particularly during mitosis when the plane is essential for determining the size of the two daughter cells. The cell division plane is perpendicular to the plane of chromosome segregation, but different types of organisms have different cell division mechanisms to suit their morphology and function.
