The Carbon Cycle01:14

The Carbon Cycle

43.7K
Carbon is the basis of all organic matter on Earth, and is recycled through the ecosystem in two primary processes: one in which carbon is exchanged among living organisms, and one in which carbon is cycled over long periods of time through fossilized organic remains, weathering of rocks, and volcanic activity. Human activities, including increased agricultural practices and the burning of fossil fuels, has greatly affected the balance of the natural carbon cycle.

Ecological Succession02:17

Ecological Succession

21.5K
Ecological succession is influenced by the processes of facilitation, inhibition, and toleration. Facilitation occurs when early successional species create more favorable ecological conditions for subsequent species, such as enhanced nutrient, water, or light availability. In contrast, inhibition happens when early successional species create unfavorable ecological conditions for potential successive species, such as limiting resource availability. In some cases, later successional species...

What is Evolutionary History?

43.4K
Scientists record evolutionary history by analyzing fossil, morphological, and genetic data. The fossil record documents the history of life on Earth and provides evidence for evolution. However, both fossil and living organisms offer evidence that outlines Earth’s evolutionary history.

Stereotypes, Prejudice, and Discrimination

95.4K
Humans are very diverse and although we share many similarities, we also have many differences. The social groups we belong to help form our identities (Tajfel, 1974). These differences may be difficult for some people to reconcile, which may lead to prejudice toward people who are different. Prejudice is a negative attitude and feeling toward an individual based solely on one’s membership in a particular social group (Allport, 1954; Brown, 2010). Prejudice is common against people who...

Electromotive Force02:36

Electromotive Force

30.2K
Electricity is generated by either electrons or ions flowing through a solution or a conducting medium. This flow of electrons or specifically electrical charge is defined as an electric current. When electrons move through a wire, they generate an electric current. It can be recalled  that in a redox reaction, electrons are lost and gained. In the spontaneous redox reaction of zinc  with copper, when zinc is immersed in a copper ion solution, a transfer of electrons from one substance to...

Area of Science:

  • Dermatology
  • Parasitology
  • Pediatric Medicine

Background:

  • Scabies is a contagious skin infestation caused by the mite Sarcoptes scabiei.
  • Nodular scabies represents a delayed hypersensitivity reaction to mite antigens.
  • It is characterized by persistent, intensely pruritic nodules, often on typical scabies sites.

Observation:

  • A case of nodular scabies in an infant is presented.
  • The infant exhibited persistent, pruritic nodules.
  • This presentation occurred despite treatment for the initial scabietic infestation.

Findings:

  • Nodular scabies can manifest as a prolonged dermatological condition.
  • The hypersensitivity reaction may persist long after the mites are eradicated.
  • Infants are susceptible to this atypical presentation of scabies.

Implications:

  • Nodular scabies requires prolonged management strategies beyond standard scabicide therapy.
  • Recognition of this entity is crucial for appropriate diagnosis and treatment in infants.
  • Further research into the immunopathogenesis of nodular scabies is warranted.
