Summary
Transport networks in eukaryotes adapt to environmental changes, developing hierarchical structures and a system-spanning backbone. Their dynamics resemble glassy systems with slow changes and bursts of reorganization.
Area of Science:
- Biology
- Complex Systems
- Network Science
Background:
- Transport networks are crucial for eukaryotic life (fungi, plants, animals, slime molds).
- These networks exhibit adaptive strategies to respond to environmental stimuli and damage.
Purpose of the Study:
- To model adapting network architectures using a generic dynamical system.
- To investigate the emergent properties of these networks under dynamic conditions.
Main Methods:
- Utilized a generic dynamical system model on weighted graphs.
- Conducted simulations to observe network evolution and equilibration dynamics.
Main Results:
- Observed the development of hierarchical organization in weighted network architectures.
- Identified the formation of a system-spanning backbone in simulated networks.
- Characterized long-term dynamics as glassy, with slow changes and bursts of reorganization.
Conclusions:
- Adapting transport networks naturally evolve towards hierarchical structures with a central backbone.
- The dynamics of these adaptive networks mirror behaviors seen in glassy systems, highlighting complex temporal organization.

01:32Assembly of Complex Microtubule Structures
2.8K
Complex microtubule structures are present in resting cells and in dividing cells. In resting cells, they are responsible for maintaining the cellular architecture, tracks for intracellular transport, positioning of organelles, assembly of cilia and flagella. They mediate the bipolar spindle assembly for chromosomal segregation and positioning of the cell division plate in dividing cells. The formation of microtubule complex structures depends on the cell type, cell stage, and cell function.

01:18Assembly of Cytoskeletal Filaments
28.4K
Cytoskeletal filaments are polymeric forms of smaller protein subunits. However, individual cytoskeletal filaments may easily disassemble or associate with other similar filaments to form rigid structures. Microfilaments, made of actin monomers, rely on actin-binding proteins to form bundles and create networks of individual actin filaments. Microtubules rely on microtubule-associated proteins (MAPs) to form sturdy cylindrical structures. However, the proteins involved in forming complex...

3.3K
Neural circuits and neuronal pools are two of the main structures found in the nervous system. Neural circuits are networks of neurons that work together to carry out a specific task or process. They consist of interconnected neurons and glial cells, which provide structural and metabolic support.
Neuronal pools are collections of nerve cells with similar functions and interact through chemical and electrical signals. These pools include both interneurons (the central neural circuit nodes that...

7.2K
Actin is a family of globular proteins that are highly abundant in eukaryotic cells. It makes up approximately 1-5% of total cell protein concentration. Actin monomers polymerize to form a complex network of polarized filaments, the actin cytoskeleton, that plays a crucial role in many cellular processes, including cell motility, division, endocytosis, and metastasis of cancer cells.

01:11Formation of Higher-order Actin Filaments
3.8K
The polymerization of G-actin monomers into filamentous F-actin is a multi-step process. Once the F-actins are formed, they can bundle together in different arrangements to form higher-order networks and regulate cellular functions. Common examples include the formation of lamellipodia and filopodia at the cell's leading edge by actin reorganization in a migrating cell. The microvilli on the brush border epithelial cells are also formed through the F-actin network.

01:14Stability of structures
609
In mechanical engineering, the stability of systems under various forces is critical for designing durable and efficient structures. One fundamental way to explore these concepts is by analyzing systems like two rods connected at a pivot point, O, with a torsional spring of spring constant k at the pivot point. This system is similar in appearance to a scissor jack used to change tires on a car. In this case, the arms of the linkage (equivalent to the rods in this system) are entirely vertical,...
