  • What is the drug Captagon?

    Why in the News?

    Captagon, the “poor man’s cocaine,” has become increasingly popular among young adults in the Middle East and North Africa.

    What is the Drug Captagon?

    • Captagon is a synthetic drug that was originally developed in Germany in the 1960s and 1970s.
    • It was initially created as a pharmaceutical treatment for attention deficit disorders, narcolepsy, and sometimes depression.
    • The primary active ingredient in Captagon is fenethylline, a compound that, once ingested, is metabolized into two powerful stimulants: amphetamine and theophylline.
    • These substances stimulate the central nervous system, leading to increased alertness, reduced fatigue, and a sense of euphoria.

    How Addictive is Captagon?

    • Captagon is highly addictive due to its powerful effects on the brain and body.
    • As a psychostimulant, Captagon significantly impacts the central nervous system, leading to a range of effects that can make it very difficult for users to stop taking the drug once they start.
    • It is also reportedly used by fighters in conflict zones to enhance their endurance and suppress fatigue.
    • The primary effects of Captagon include:
    1. Euphoria: Users often experience an intense feeling of happiness or well-being.
    2. Increased Wakefulness: The drug reduces the need for sleep, keeping users awake and alert for extended periods.
    3. Enhanced Physical and Mental Performance: Users may feel stronger, more focused, and more capable of performing both physically and mentally demanding tasks.
    • However, the heavy use of Captagon comes with serious risks such as cognitive impairment, cardiovascular issues, and risk of addiction.

    Where is Captagon Made?

    • In recent years, Syria the “narco state” of Middle East has emerged as the largest producer of Captagon.
    • Its production increased after 2011 Arab Spring protests, which led to civil unrest and conflict in the region.

    PYQ:

  • Extremophile bacteria have learnt to survive microwaves

    Why in the News?

    Researchers have isolated extremophile bacteria from harsh environments like volcanic vents, permafrost, acid mines, deep-sea hydrothermal vents, and lakes beneath polar ice caps.

    What are Extremophiles?

    • Extremophiles are microorganisms that thrive in extreme environmental conditions where other life forms typically cannot survive.
    • For example: Volcanic vents, Permafrost, Acid mines, Deep-sea hydrothermal vents, dark lakes buried beneath polar ice caps, on the exteriors of spacecraft, around nuclear waste storage sites.

    Adaptation and Evolution:

    • Extremophiles have developed unique biological and biochemical processes over millions of years to adapt to diverse habitats.
    • Unlike more complex life forms, which have one set of proteins, extremophiles have multiple sets of proteins, each adapted to specific environmental conditions.
    • These proteins are ‘activated’ based on the surrounding environment, enabling survival during extreme conditions like high temperatures, lack of water, or high acidity.
    • Significance: Some scientists believe that life on Earth may have begun as an extremophile in extreme environmental niches before spreading and adapting to more temperate ecosystems.

    About the ‘Earth Microbiome Project’

    • It is a global initiative aimed at mapping, organising, and understanding the diversity of microbial life across different environmental niches on Earth.
    • The project was founded in 2010.
    • Objective: 
      • To sequence 200,000 genetic samples from diverse environments.
      • To assemble 500,000 microbial genomes, creating a comprehensive map of microbial diversity on Earth.
    • Significance:
      • The project is part of broader efforts to understand the microbial world, which is still in its infancy.
      • It is related to other significant projects like the ‘Earth Biogenome Project,’ which aims to sequence the genomes of all eukaryotic organisms on the planet.
      • Understanding microbial diversity has numerous biological and industrial applications, such as developing new enzymes for molecular biology or finding new ways to adapt organisms to challenging environments.
