Effect of Sea Water on Concrete01:22

Effect of Sea Water on Concrete

1.1K
Concrete exposed to seawater can undergo degradation like the dissolution of ettringite and gypsum, increasing the material's porosity and decreasing its strength. In contrast, the crystallization of salts within the concrete's pores can cause expansion, particularly above the waterline where evaporation occurs. Nonetheless, this expansion only happens when seawater, enabled by the concrete's permeability, manages to infiltrate the structure.
Concrete in areas between tide marks,...

Keystone Species01:39

Keystone Species

24.9K
Measures of species biodiversity, such as richness (i.e., the number of species present) and evenness (i.e., their relative abundance), describe an ecological community’s structure. Many factors affect community structure, including abiotic factors (e.g., sunlight and nutrients), disturbances (e.g., fire or flood), species interactions (e.g., predation or competition), and chance events (e.g., foreign species invasion). Certain species—such as keystone species—also play a...

Sustainable Development

15.2K
As the human population continues to grow and use resources, we must be mindful of our planet’s natural limits. Sustainable development provides a pathway to maintain and improve human life now while also ensuring that future generations will have the resources that they need. The long-term success of sustainability efforts rests on understanding the interplay between human actions and ecological systems.

Development of the Lymphatic System01:15

Development of the Lymphatic System

2.1K
The development of lymphatic tissues and vessels in embryonic life begins around the fifth week. These structures originate from the mesoderm layer, with lymph sacs emerging from developing veins.
The first lymph sacs to form are the paired jugular lymph sacs located at the junction of the internal jugular and subclavian veins. From these sacs, lymphatic capillary plexuses extend to the thorax, upper limbs, neck, and head, eventually forming lymphatic vessels. Each jugular lymph sac maintains a...

Language Development01:22

Language Development

920
Children master language quickly and with relative ease, supported by both biological predisposition and reinforcement. B. F. Skinner (1957) proposed that language is learned through reinforcement, while Noam Chomsky (1965) argued that language acquisition mechanisms are biologically determined.
The critical period for language acquisition suggests that the ability to acquire language is at its peak early in life. As people age, this proficiency decreases. Language development begins very...

Development of Immunocompetence01:22

Development of Immunocompetence

918
The initiation of cell-mediated immunity can be observed as early as the third month of fetal growth, with active antibody-mediated immunity following approximately one month later.
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
Subsequent T...

Area of Science:

  • Developmental Biology
  • Marine Biology
  • Immunology

Background:

  • Larvae are distinct postembryonic life stages found across many animal phyla.
  • Echinoids, including sea urchins and sand dollars, possess transparent, rapidly developing larvae.
  • Sea urchin larvae are a well-established model system with extensive genomic and imaging resources.

Purpose of the Study:

  • To review literature on key postembryonic processes in sea urchin larvae.
  • To highlight the suitability of sea urchin larvae as experimental models.
  • To support the role of endocrine signaling, immunity, and host-microbe interactions in larval development.

Main Methods:

  • Literature review of existing research on sea urchin larval biology.
  • Analysis of studies focusing on endocrine signaling, immunity, and host-microbe interactions.
  • Synthesis of evidence supporting sea urchin larvae as model organisms.

Main Results:

  • Sea urchin larvae exhibit rapid development and transparency, ideal for observation.
  • Strong evidence indicates significant roles for endocrine signaling in larval development.
  • Emerging data highlights the importance of immunity and host-microbe interactions in larval physiology.

Conclusions:

  • Sea urchin larvae are highly valuable experimental systems for studying fundamental biological processes.
  • Endocrine signaling, immunity, and host-microbe interactions are critical components of larval development and physiology.
  • Future research should leverage sea urchin larvae to further investigate these complex interactions.
