    Insights

    Melioidosis, a pneumonia and sepsis cause, is underreported in Nigeria. A study found 30% of healthy Nigerians showed past exposure to Burkholderia pseudomallei, the bacteria causing melioidosis.

    Area of Science:

    • Infectious Diseases
    • Microbiology
    • Epidemiology

    Background:

    • Melioidosis is a significant, yet underreported, cause of community-acquired pneumonia and sepsis in Nigeria.
    • Early diagnosis and treatment are crucial for improving patient outcomes in melioidosis cases.

    Purpose of the Study:

    • To investigate the seroprevalence of melioidosis in a healthy Nigerian population.
    • To assess the extent of past exposure to Burkholderia pseudomallei in Nigeria.

    Main Methods:

    • A cross-sectional study was conducted involving 500 healthy participants from Nigeria.
    • A Burkholderia pseudomallei protein microarray was utilized to detect serologic responses.

    Main Results:

    • A significant serologic response, indicating past exposure to Burkholderia pseudomallei, was observed in 30% of the participants.
    • The findings suggest a higher prevalence of melioidosis exposure than previously recognized in Nigeria.

    Conclusions:

    • Melioidosis exposure is prevalent in the healthy Nigerian population.
    • Increased awareness and diagnostic efforts for melioidosis in Nigeria are warranted.

    The Evidence for Evolution02:55

    The Evidence for Evolution

    Genetic variations accumulating within populations over generations give rise to biological evolution. Evolutionary changes can result in the formation of novel varieties and entire new species. These changes are responsible for the diverse forms of life inhabiting the planet. The evidence for evolution suggests that all living organisms descended from common ancestors.

    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,...

    Confirmation Biases01:31

    Confirmation Biases

    The confirmation bias is the tendency to focus on information that confirms our existing beliefs and ignore information that is inconsistent with our expectations. For example, if you think that your professor is not very nice, you notice all of the instances of rude behavior exhibited by the professor while ignoring the countless pleasant interactions he is involved in on a daily basis. Have you ever fallen prey to the confirmation bias, either as the source or target of such bias?

    Stereotype Threat and Self-fulfilling Prophecies

    When we hold a stereotype about a person, we have expectations that he or she will fulfill that stereotype. A self-fulfilling prophecy is an expectation held by a person that alters his or her behavior in a way that tends to make it true. When we hold stereotypes about a person, we tend to treat the person according to our expectations. This treatment can influence the person to act according to our stereotypic expectations, thus confirming our stereotypic beliefs. Research by Rosenthal and...

    Routes of Persuasion

    Persuasion is the process of changing our attitude toward something based on some kind of communication. Much of the persuasion we experience comes from outside forces. How do people convince others to change their attitudes, beliefs, and behaviors? What communications do you receive that attempt to persuade you to change your attitudes, beliefs, and behaviors?

    What is Evolutionary History?

    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.
