What is Natural Selection?

What is Natural Selection?

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.

Nature and Nurture

Nature and Nurture

Many human characteristics, like height, are shaped by both nature—in other words, by our genes—and by nurture, or our environment. For example, chronic stress during childhood inhibits the production of growth hormones and consequently reduces bone growth and height. Scientists estimate that 70-90% of variation in height is due to genetic differences among individuals, and 10-30% of variation in height is due to differences in the environments that individuals experience,...

Intracellular Signaling Affects Focal Adhesions

Intracellular Signaling Affects Focal Adhesions

Integrins act both as extracellular input receivers and as intracellular processing activators. As their name suggests, integrins are entirely integrated into the membrane structure. Their hydrophobic membrane-spanning regions interact with the phospholipid bilayer's hydrophobic region. These membrane receptors provide extracellular attachment sites for effectors like hormones and growth factors. They activate intracellular response cascades when their effectors are bound and active.

Chirality in Nature

Chirality in Nature

Chirality is the most intriguing yet essential facet of nature, governing life’s biochemical processes and precision. It can be observed from a snail shell pattern in a macroscopic world to an amino acid, the minutest building block of life. Most of the snails around the world have right-coiled shells because of the intrinsic chirality in their genes. All the amino acids present in the human body exist in an enantiomerically pure state, except for glycine - the sole achiral amino acid.

The Wave Nature of Light

The Wave Nature of Light

The nature of light has been a subject of inquiry since antiquity. In the seventeenth century, Isaac Newton performed experiments with lenses and prisms and was able to demonstrate that white light consists of the individual colors of the rainbow combined together. Newton explained his optics findings in terms of a "corpuscular" view of light, in which light was composed of streams of extremely tiny particles traveling at high speeds according to Newton's laws of motion.

Limits to Natural Selection

Limits to Natural Selection

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:

Epidemiology
Infectious Diseases
Veterinary Public Health

Background:

Natural-focal infections (NFI) pose a significant public health concern.
Understanding the epizootiologic dynamics of NFI is crucial for effective disease control.

Purpose of the Study:

To analyze the epizootologic manifestations of natural-focal infections in Southern Russia during 2015.
To assess the prevalence and distribution of various NFI in the region.

Main Methods:

Utilized reports from governmental health surveillance agencies and research institutes.
Analyzed 37,738 samples of field material, with a focus on tularemia, Crimea hemorrhagic fever, and West Nile fever.
Employed Excel software for data processing.

Main Results:

Detected causative agents for 15 nosologic forms of NFI.
Positive samples were most frequent for tick-borne borreliosis (612), Crimea hemorrhagic fever (279), and tularemia (237).
Tularemia, Crimea hemorrhagic fever, and West Nile fever were among the most studied diseases.

Conclusions:

Observed an increased activity of natural foci for bacterial (tularemia, tick-borne borreliosis), rickettsial (tick-borne spotted fevers), and viral infections (Crimea hemorrhagic fever, West Nile fever, tick-borne viral encephalitis).
Highlighted the importance of prophylaxis and continuous monitoring of natural foci in Southern, North Caucasian, and Crimea federal districts.
