Pygmy hog

  • Recently, eighteen captive-bred pygmy hogs were released in western Assam’s Manas National Park and Tiger Reserve.

About Pygmy hog:

  • It is the smallest and rarest species of wild pig in the world.
  • It is one of the very few mammals that build its own home, or nest, complete with a ‘roof’.
  • It is an indicator species as its presence reflects the health of its primary habitat, tall and wet grasslands.
  • Habitat: It prefers undisturbed patches of grassland dominated by early succession riverine communities, typically comprising dense tall grass intermixed with a wide variety of herbs, shrubs and young trees.
  • Currently, the viable population of this pig in the wild is in the Manas Tiger Reserve in Assam.

Conservation status:

  • IUCN: Critically Endangered
  • The Wildlife Protection Act, 1972: Schedule I

Key facts about Manas National Park

  • It is located in the state of Assam. It is contiguous with the Royal Manas National Park in Bhutan.
  • It is a national park, UNESCO Natural World Heritage site, a Project Tiger reserve, an elephant reserve and a biosphere reserve.
  • Flora: It contains some of the largest remaining grassland habitats in the sub-Himalayan grassland ecosystems.
  • Fauna: The Park is known for its rare and endangered endemic wildlife such as the Assam roofed turtle, hispid hare, golden langur and pygmy hog.
  • The Manas River is a major tributary of Brahmaputra River, which passes through the Manas National Park.


  • Researchers detected senescent macrophages in the lung that not only remained but also supported tumour growth in a recent Cancer Cell study.

About Macrophages:

  • Macrophages are a type of white blood cell that plays an important role in the human immune system.
  • They are involved in the detection, phagocytosis, and destruction of bacteria and other harmful organisms.
  • The term macrophage is formed by the combination of the Greek terms “makro” meaning big, and “phagein” meaning eat.
  • They are essential for the maintenance and defence of host tissues, doing so by sensing and engulfing particulate matter and, when necessary, initiating a pro-inflammatory response. 
  • They can modify themselves to form different structures in order to fight various different microbes and invaders. In this way, macrophages provide the first line of defense in protecting the host from infection.
  • They are also involved in the development of non-specific or innate immunity.
  • Macrophages produce a variety of cytokines, which are signaling molecules that communicate with other cells of the immune system. Cytokines play a role in inflammation, tissue repair, and the adaptive immune response.
  • They migrate to and circulate within almost every tissue, patrolling for pathogens or eliminating dead cells.
  • Macrophages may have different names according to where they function in the body. For example, macrophages present in the brain are termed microglia and in the liver sinusoids, they are called Kupffer cells.

What is Cellular Senescence?

  • It refers to a state of stable cell cycle arrest in which proliferating cells become resistant to growth-promoting stimuli, typically in response to DNA damage. 
  • During this phase, the cell undergoes numerous phenotypic and metabolic changes.
  • Senescent cells accumulate during ageing and have been implicated in promoting a variety of age-related diseases.
  • Cellular senescence can compromise tissue repair and regeneration, thereby contributing towards ageing.
  • Removal of senescent cells can attenuate age-related tissue dysfunction and extend the health span.
  • Senescence can also act as a potent anti-tumour mechanism by preventing the proliferation of potentially cancerous cells.

Sela Tunnel Project

  • The BRO officials recently said that nearly 96 percent of the work on the strategically crucial Sela Tunnel is complete, and it is likely to be inaugurated by year-end.
