Detection of Black Holes01:10

Detection of Black Holes

2.6K
Although black holes were theoretically postulated in the 1920s, they remained outside the domain of observational astronomy until the 1970s.
Their closest cousins are neutron stars, which are composed almost entirely of neutrons packed against each other, making them extremely dense. A neutron star has the same mass as the Sun but its diameter is only a few kilometers. Therefore, the escape velocity from their surface is close to the speed of light.
Not until the 1960s, when the first neutron...

What is Natural Selection?01:32

What is Natural Selection?

129.0K
Natural selection is an evolutionary process in which individuals with survival-promoting traits reproduce at higher rates. These favorable traits become more common within a population or species. Naturally selected traits initially arise via random genetic mutations. In order for selection to occur, there must be variation within a population, the trait controlling the variation must be heritable, and there must be an evolutionary advantage for variation in the trait.

Types of Selection

45.0K
Natural selection influences the frequencies of particular alleles and phenotypes within populations in several different ways. Primarily, natural selection can be directional, stabilizing, or disruptive. Directional selection favors one extreme trait and shifts the population towards that phenotype while selecting against individuals displaying alternate traits. Stabilizing selection favors an intermediate trait with a narrow range of variation. Deviation from the optimal phenotype towards an...

Frequency-dependent Selection01:21

Frequency-dependent Selection

24.0K
When the fitness of a trait is influenced by how common it is (i.e., its frequency) relative to different traits within a population, this is referred to as frequency-dependent selection. Frequency-dependent selection may occur between species or within a single species. This type of selection can either be positive—with more common phenotypes having higher fitness—or negative, with rarer phenotypes conferring increased fitness.

Limits to Natural Selection

34.9K
Organisms that are well-adapted to their environment are more likely to survive and reproduce. However, natural selection does not lead to perfectly adapted organisms. Several factors constrain natural selection.

Area of Science:

  • Ophthalmology
  • Glaucoma Research
  • Laser Therapy

Background:

  • Primary open-angle glaucoma (POAG) management typically begins with medical therapy.
  • Alternative or complementary treatments are considered when medical therapy is insufficient.
  • Selective laser trabeculoplasty (SLT) benefits in Black African populations with POAG remain understudied.

Purpose of the Study:

  • To evaluate the efficacy of selective laser trabeculoplasty in reducing intraocular pressure (IOP).
  • To assess SLT outcomes specifically in African Black patients diagnosed with POAG.

Main Methods:

  • A retrospective study included 44 Black patients (82 eyes) with POAG treated between March 2010 and March 2011.
  • All patients had accessible trabecular meshwork for 360° treatment.
  • Treatment involved two 180° sessions of SLT, 15 days apart; success was defined as ≥3mm Hg IOP reduction without additional medication.

Main Results:

  • Mean IOP reduction ranged from 3.81mm Hg (20.67%) at 15 days to 4.95mm Hg (26.86%) at 6 months.
  • Success rates varied, with a high of 83.78% at 1 month and 72.09% at 3 months.
  • The mean age of participants was 55.94±11.66 years, with an initial mean IOP of 18.43±4.81mm Hg.

Conclusions:

  • Selective laser trabeculoplasty demonstrates effectiveness in African Black patients with POAG.
  • SLT efficacy appears comparable to carbonic anhydrase inhibitors or prostaglandin analogs.
  • SLT presents a potential complementary or alternative treatment option to POAG medications for this demographic.
