An ancient system that could bring water to dry areas (DownToEarth)

  • 18 Jan 2024

Why is it in the News?

Some of Africa’s dry areas face serious water shortages due to minimal rainfall. An ancient system of drawing water from aquifers, the “qanat system”, could help.

What is the Qanat system?

  • The qanats have been used for centuries in arid and semi-arid parts of North Africa, the Middle East and Asia, where water supplies are limited.
  • It’s known by a variety of names, “foggara” in North Africa, “falaj” in Oman and “qarez” in parts of Asia.
  • It’s thought to have been developed in Persia in the first millennium BC.
    • As the Islamic Empire spread across the Arabian Peninsula, the Levant, north Africa and parts of Europe from 661 to 750 CE, so did knowledge about qanats.
  • Today, some of the region’s qanat systems, like those in Iran, are protected under heritage status.
  • Some of these qanats, although declining in number, are still used.
    • They are largely protected for historical and cultural reasons.

How does the qanat system work?

  • There are bodies of water underground known as aquifers, some of which can be found at the tops of valleys or near mountains.
    • A qanat system taps these aquifers and, using underground tunnels, moves the water, using gravity, over many kilometres.
    • The tunnel then exits at a lower-lying area.
  • When the water exits the tunnel, farmers can use it to irrigate their crops.
    • People can also access the water along the stretch of the tunnel using wells.
  • It’s a system that’s managed by everyone and its benefits are shared.
    • Everybody has a vested interest and a role to play and community bonds can be strengthened.

Advantages of qanat systems:

  • Efficient use of water: Qanats allow for the extraction and transport of groundwater from deep underground sources to the surface.
    • This allows for a more efficient use of water resources, as the water is extracted and transported to the surface for irrigation and other purposes.
  • Sustainable water supply: Qanats can provide a reliable and sustainable source of water for communities, even in arid regions where surface water is scarce.
  • Cool and humid air supply: The cool and humid air that flows through the qanat can be used to provide a natural air conditioning system for buildings, as well as to irrigate crops and orchards.
  • Low maintenance: Qanats require minimal maintenance once they are constructed, making them a cost-effective and long-lasting water supply solution.
  • Disaster resilience: Qanats are resilient to natural disasters such as earthquakes and floods, as they are located underground and protected from damage.

What are Oxbow Lakes?

  • Oxbow lakes are crescent-like water bodies formed due to erosion and deposition in meanders of rivers.
  • Meanders are loops or curved structures formed in the course of a river due to friction or tectonic activity.
  • The speed of water flow in the outer section of this meander is more than the inner part causing its neck to become narrower over time.
  • Eventually, the size of this loop increases making it harder for the river to flow through it so it opts for a straight path.
  • Finally, the ends of this meandered loop are separated by deposition of sediments or silt separating the river and a horseshoe-like structure called oxbow lake.

Microalgae are Adapting to Warming Climate (DownToEarth)

  • 18 Oct 2023

Why in the News?

A recent study finds microalgae are firing up a light-responsive protein to use sunlight for growth.

What is the Microalgae?

  • Microalgae are microscopic algae prevalent in freshwater and marine environments, consisting of unicellular species that can exist independently or in chains and groups.
  • Comprising unicellular algal varieties such as green algae, diatoms, and dinoflagellates, these organisms exhibit sizes ranging from a few micrometres to several hundred micrometres.
  • Their colour, determined by predominant pigments, categorizes them into groups like green, red, or brown.
  • Unlike higher plants, microalgae lack roots, stems, or leaves, and they predominantly engage in photosynthesis, fueled by photosynthetic pigments.
  • Heterotrophic microalgae, lacking these pigments, rely on other organisms for sustenance.

Significance:

  • Microalgae play a foundational role in the aquatic food chain, offering vital nutrients for zooplankton, small fish, and various aquatic organisms.
  • They serve as a primary food source for filter-feeding organisms.
  • Moreover, photosynthetic microalgae contribute significantly to global carbon and oxygen cycles, absorbing carbon dioxide and generating oxygen through photosynthesis.
  • Approximately half of atmospheric oxygen is produced by these organisms.
  • Microalgae can also establish symbiotic relationships, as seen in their association with corals (zooxanthellae), providing nutrients through photosynthesis.
  • Certain microalgae, like Nostoc, Anabaena, and Oscillatoria, exhibit nitrogen-fixing capabilities.
  • Additionally, microalgae are rich in nutrients and can be consumed by humans. Notable examples like Spirulina and Chlorella are often utilized as dietary supplements.

What are Macroalgae?

  • Macroalgae, commonly known as seaweeds, are marine plants engaging in photosynthesis but reproducing without flowers.
  • Visible to the naked eye, in contrast to microalgae, they typically grow attached to the seabed or reef substrate.
  • These macroscopic algae play crucial roles in reef ecosystems, providing both food and habitat for a diverse array of species while contributing significantly to nutrient dynamics.

“FLip” mutations of SARS-COV-2 may be evading immunity and leading to a surge in COVID cases, suggest researchers (DownToEarth)

  • 25 Dec 2023

Why is it in the News?

The omicron subvariant JN.1. is likely to soon become the dominant lineage of the SARS-CoV-2 virus worldwide, according to researchers at the University of Tokyo. The subvariant has a mutation in its spike protein, L455S, also called a “FLip” mutation.

Context:

  • The mutations denoted as L455S and L455F are termed "FLip" mutations due to their role in interchanging the positions of amino acids F and L within the spike protein.
  • These mutations enhance the virus's transmissibility.
  • The substitution associated with these mutations reduces the receptor binding capacity of angiotensin-converting enzyme 2 (ACE2), a protein present in epithelial cells across various body parts, including the lungs, heart, and kidneys.
  • ACE2 serves as a crucial entry point for the SARS-CoV-2 virus, binding through its spike-like protein on the virus's surface.
  • The FLip mutations, specifically L455F and F456L, are characterized by the swapping of positions between two amino acids, F and L, within the spike protein.

What is Flip Mutation?

  • A flip mutation, also known as bit flip mutation, is a genetic operator used in evolutionary algorithms, particularly genetic algorithms (GAs).
  • It works by randomly flipping the values of individual genes (bits) within a chromosome, introducing small changes to the genetic makeup of an individual.
    • Imagine a chromosome as a string of 0s and 1s, representing the genetic code for a specific trait or characteristic.
  • A flip mutation randomly selects one or more of these bits and changes their values.
    • For example, a 0 might be flipped to a 1, or vice versa.
  • The following image depicts flip mutation:

How does it work:?

  • Individual selection: An individual is selected from the population.
  • Gene selection: One or more genes (bits) within the individual's chromosome are randomly chosen.
  • Bit flipping: The value of each selected gene is flipped. This means that a 0 is changed to a 1, and vice versa.

  • Its feeding habits often leave the field resembling it has been grazed by cattle.
  • During an outbreak, the pest multiplies rapidly and moves in swarms from one field to another, similar to an army, causing harm to crops.
  • The pest population tends to increase under favorable conditions, particularly when there is a rise in temperatures coupled with dryness.

State of the Cryosphere Report 2023 (DownToEarth)

  • 18 Nov 2023

Why in the News?

As per the 2023 State of the Cryosphere report, the anticipated disappearance of almost all tropical glaciers, a significant majority of mid-latitude glaciers, and polar regions is expected, even if global efforts successfully limit the rise in temperatures to 2 degrees Celsius above preindustrial levels.

About the State of the Cryosphere Report 2023:

  • The State of the Cryosphere Report annually assesses the condition of Earth's snow and ice regions, and has been reviewed and endorsed by over 60 leading cryosphere scientists.
  • This report is published by The International Cryosphere Climate Initiative (ICCI.)
  • The cryosphere is a term for the regions of our globe that are covered in ice and snow – either seasonally or year-round.
  • The Report describes how a combination of melting polar ice sheets, vanishing glaciers, and thawing permafrost will have rapid, irreversible, and disastrous impacts worldwide.

Key findings in the report on the impact of 2°C of warming include:

  • Ice sheets: nearly all of Greenland, much of West Antarctica, and even vulnerable portions of East Antarctica will be triggered to very long-term, inexorable sea-level rise.
  • Glaciers: extensive, irreversible ice loss from the world’s glaciers in many major river basins, with some disappearing entirely.
  • As glaciers melt, risks of catastrophic events such as landslides, sudden ice shears, and glacial lake outburst floods increase.
  • Sea ice: extensive sea ice loss at both poles, with severe feedback to global weather and climate.
  • By 2°C, the Arctic Ocean will be sea ice-free in summer every year, potentially for several months.
  • Permafrost: extensive permafrost thaw and resulting greenhouse gas emissions will cause temperatures to continue to rise, even once human emissions reach zero.
  • At 2°C, annual total permafrost emissions (both CO2 and methane) would total the size of the entire European Union’s emissions from 2019.
  • Polar ocean acidification: year-round, permanent corrosive ocean acidification conditions in many regions of Earth’s polar and near-polar seas.
  • Shell-building animals and commercial fisheries that rely on them in the food chain may not survive.

About International Cryosphere Climate Initiative (ICCI):

  • It was formed in 2009 following COP-15 in Copenhagen
  • ICCI is a network of senior policy experts and researchers working with governments and organizations to create, shape, and implement initiatives designed to preserve as much of the Earth’s cryosphere as possible.
  • ICCI programs target the unique climate dynamics at work in the cryosphere, while at the same time lending increased urgency to global climate efforts aimed at CO2 and other greenhouse gases by communicating the unexpected rapidity and global implications of cryosphere warming.

What is ‘noma’, the latest addition to WHO’s list of neglected tropical diseases (DownToEarth)

  • 18 Dec 2023

Why is it in the News?

The World Health Organization (WHO) on December 15, 2023, added one of the world’s most under-recognised health challenges, noma, to its official list of neglected tropical diseases (NTD).

About the Noma disease:

  • Noma is a severe gangrenous disease of the mouth and face with a mortality rate of approximately 90 per cent.
  • It is also known as cancrum oris or gangrenous stomatitis and is often associated with extreme poverty, malnutrition and poor access to sanitation and oral hygiene.
  • The name of the disease comes from the Greek word “nom?”, meaning “to devour”, as noma eats away facial tissue and bones if not treated early.
  • Noma mainly affects children aged 2-6 years old and is found most commonly among those living in poor communities.
  • The illness’s ‘hidden’ or neglected nature is most likely due to the fact that it affects the world’s most marginalised children.
  • Noma is associated with a number of risk factors, including poor oral hygiene, malnutrition, weakened immune systems, infections, and extreme poverty.
    • While the disease is not contagious, it prefers to attack when the body’s defences are weak.
  • The NTD often starts as an ulcer on the mucous membrane lining, commonly after a bout of measles or other diseases, stated another 2003 study.
    • “It quickly develops into a massive necrosis, moving from the inside outward, often involving major portions of the face.
  • Treatment: “Early treatment with antibiotics, rehydration, correction of electrolytic imbalances, and administering nutritional supplements will halt the disease.
  • The patients who survive face many consequences, like significant facial disfigurement, spasms of the jaw muscles, oral incontinence and speech problems.
  • The disease is also called the ‘face of poverty’, as effective drugs like sulfonamides and penicillin and adequate surgical treatment for the effects remain inaccessible for many due to extreme poverty.
  • “The recognition of noma as an NTD aims to amplify global awareness, catalyse research, stimulate funding, and boost efforts to control the disease through multisectoral and multi-pronged approaches.

CHD1L gene (DownToEarth)

  • 04 Aug 2023

Why in the News?

A new study indicates that some individuals of African descent have a CHD1L gene variant that may be involved in controlling the human immunodeficiency virus (HIV).

What is the CHD1L gene?

  • The CHD1L gene encodes proteins that aid in repairing DNA damage within the body.
  • A specific variant of the CHD1L gene is found predominantly in the African population and has been associated with a decreased viral load (amount of HIV in the blood) of HIV-1, the most common and severe type of HIV compared to HIV-2.
  • Through the analysis of DNA from nearly 4,000 people of African descent living with HIV-1, researchers identified the presence of a gene variant of CHD1L located on chromosome 1.
  • Individuals carrying this particular gene variant exhibited a low viral load, reducing their risk of transmitting the virus and slowing the progression of their own HIV-related illness.
  • The study suggests that between 4% and 13% of people with African origins could be carrying this specific CHD1L gene variant.
