Detection of Black Holes

Detection of Black Holes

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...

Epistasis

Epistasis

In addition to multiple alleles at the same locus influencing traits, numerous genes or alleles at different locations may interact and influence phenotypes in a phenomenon called epistasis. For example, rabbit fur can be black or brown depending on whether the animal is homozygous dominant or heterozygous at a TYRP1 locus. However, if the rabbit is also homozygous recessive at a locus on the tyrosinase gene (TYR), it will have an unshaded coat that appears white, regardless of its TYRP1...

Molecular Models

Molecular Models

Physical models representing molecular architectures of chemical compounds play essential roles in understanding chemistry. The use of molecular models makes it easier to visualize the structures and shapes of atoms and molecules.

Area of Science:

Gastroenterology
Internal Medicine
Emergency Medicine

Background:

Upper gastrointestinal bleeding is a common medical emergency.
Esophageal pathology can present with severe bleeding and hemodynamic instability.

Observation:

An 85-year-old male presented with hematemesis (black fluid) and melaena.
The patient was hypotensive and severely anemic upon arrival.

Findings:

Gastroscopy revealed extensive necrosis of the entire esophagus.
The patient succumbed to hypovolemic shock within 24 hours of admission.

Implications:

Esophageal necrosis is a critical condition with high mortality.
Prompt diagnosis and management are crucial for upper GI bleeding patients.
This case highlights the severity of esophageal necrosis and its rapid progression.
