Gangetic River Dolphin

Recently, National Dolphin Research Centre (NDRC) was inaugurated in Patna in Bihar.

  • It is India’s 1st centre for research on conserving the Gangetic river dolphin.
    • Scientific name – Platanista gangetica gangetica
    • Common name – Susu, Shushak, Side-swimming Dolphin
  • Distribution – They are endemic to River Ganga.
  • Ganges-Brahmaputra-Meghna and Karnaphuli-Sangu river systems of Nepal, India, and Bangladesh.

Bihar has around 50% of the estimated 3,000 Gangetic dolphins in India.

  • Habitat – Only freshwater and prefer deep water, live in a zone of little or no current.


The Gangetic river dolphin is one of 4 freshwater dolphin species in the world. The other 3 are found in the Yangtze River in China (now extinct), the Indus River in Pakistan and the Amazon River in South America.

  • Features – It is functionally blind and finds its way and prey in river waters through echolocation.
  • Being a mammal, it cannot breathe in water so it surfaces above the water every 30-40 seconds to breathe with a slit similar to a blowhole on top of its head acts as a nostril.
  • They are frequently found alone or in small groups, and generally a mother and calf travel together.
  • Calves are chocolate brown at birth and then have grey-brown smooth, hairless skin as adults.
  • Females are larger than males.
  • Major Threats – Unintentional killing through entanglement in fishing gear, pollution and overexploitation of prey.
  • Poaching for dolphin oil, used for medicinal purposes.
  • Habitat destruction due to development projects like dams.
  • Protection status
    • IUCN – Endangered
    • Wild Life (Protection) Act, 1972 – Schedule I
    • CITES – Appendix I

Quick Facts

  • Gangetic River Dolphin – It is India’s national aquatic animal.
  • It is state aquatic animal of Uttar Pradesh.
  • It was recently rescued in Jalaka River of Odisha, which indicates that there is presence of more freshwater dolphins in the river.
  • Project Gangetic Dolphin was launched in 2016 for conserving it.

Rajya Sabha Elections

In a recent ruling, the Supreme Court said that the elections to the Rajya Sabha required ‘utmost protection’ and the right to vote should be carried out freely without fear.

  • Rajya Sabha –It is the Upper House of the Indian Parliament, also called as Council of States

Article 80 of the Constitution lays down the maximum strength of Rajya Sabha as 250, where 12 members are nominated by the President and 238 are representatives of the States and of the 3 Union Territories.

  • QualificationArticle 84 of the Constitution lays down that
    • He/ She must be a citizen of India
    • He/ She must be not less than 30 years of age
    • He/ She must possess such other qualifications as may be prescribed in that behalf by or under any law made by Parliament.
  • Election – Members are elected by the method of indirect election in accordance with the system of proportional representation by means of the single transferable vote.
  • Electoral CollegeElected members of the Legislative Assembly of all the States.
  • Elected members of the legislative assembly of UT of Puducherry, Jammu & Kashmir and National Capital Territory of Delhi.

Rajya Sabha being a permanent house is not subject to dissolution. However one-third Members retire after every 2nd year. A member who is elected for a full term serves for a period of 6 years and on the expiration of this term retires from the membership.

  • Biennial/Bye-election – It is the election, to fill a vacancy arising otherwise than by retirement of a member.
  • Vacancy may be due to either resignation or death or disqualification of members under the 10th Schedule.
  • A member elected in a bye-election remains a member only for the remainder of the term of the member.
  • Supreme Court – It declared that Rajya Sabha elections are within the remit of Article 194(2) of the Constitution, clarifying its 2006 Kuldip Nayar judgment.

In 2006 kuldip Nayar case, Supreme Court ruled that Rajya Sabha elections were not proceedings of the legislature within the meaning of Article 194 but a mere exercise of franchise.

  • Parliamentary privileges under Articles 105(2) and 194(2) extends to other powers of elected members taking place in the legislative body even when the house is not in session.
  • Thus the members of parliament and legislative assemblies cannot claim immunity from prosecution on charges of bribery related to votes or speeches in the legislature.

Volcanic winter

Researchers from NASA used advanced computer modelling to simulate super-eruptions like the Toba event and found that volcanic winter would probably not exceed 1.5 degrees Celsius.

To qualify as a super eruption, a volcano must release more than 1,000 cubic kms of magma. These eruptions are extremely powerful and rare. The most recent one was around 22,000 years ago in New Zealand.

  • Volcanic winter – A climatic cooling effect caused by large-scale volcanic eruptions.
  • Previous studies agreed that some planet-wide cooling would occur and estimates have ranged from 2 to 8 degrees Celsius.
  • Occurrence – A massive volcanic eruption can deposit enormous amounts of ascending light coloured volcanic ash and sulphur aerosols above the troposphere and into the lower stratosphere.
  • Global cooling – These erupted particles reflect incoming solar radiation, resulting in cooler temperatures on the earth below.
  • They can remain there for 2 years causing global cooling.
  • The air between the troposphere and the stratosphere eventually mixes causing these particles to fall into the troposphere and wash down on the earth through precipitation.


One of the most severe volcanic winters occurred between 74,000 and 71,000 years ago following the eruption of the Mount Toba volcano on the island of Sumatra.

  • Challenges – The ash produced from the eruption of Mount Etna in 44 B.C. was described to have dimmed the Sun's rays and the resulting cooling caused crops to shrivel and produce famine in ancient Rome and Egypt.

Stratospheric Aerosols Injection (SAI) involves spraying large quantities of tiny particles like Sulphur dioxides or finely powdered calcium carbonate into the earth’s stratosphere to reflect sunlight and thereby reducing Earth’s temperature.

Zombie Deer Disease

Zombie deer disease is spreading and rising in USA and scientists are concerned that it could jump to humans.

  • It is a contagious degenerative disease, also known as chronic wasting disease (CWD).

The 1st case of chronic wasting disease (CWD) was discovered in Colorado in 1967.

  • Caused byA prion.

Prions are misfolded proteins that can cause normal proteins in the brain to misfold as well, leading to neurological degeneration.

  • As the degeneration continues, the afflicted animal's brain cells die, ultimately resulting in its death.
  • Vulnerable species – deer, elk, reindeer, sika deer, and moose.
  • Spread – So far in Canada, the US, Norway, Sweden and South Korea.
  • Transmission – They are reportedly spread via bodily fluids like saliva, urine, blood, or feces.
  • Symptoms – It is characterised by myriad symptoms, such as drooling, lethargy, stumbling and a vacant gaze.
  • It progressively deteriorates the brains of these animals, leading to dementia-like symptoms and eventual death.
  • Diagnosis – It can only be confirmed by testing brain or lymph node samples from dead animals.
  • There is no reliable test for live animals yet.
  • Prevention – By reducing the contact and transmission of prions among cervids and their environment.
  • Treatment – There are no treatments or vaccines available.
  • Challenges – Prions can persist in the environment for extended periods and are resisting traditional disinfection methods such as formaldehyde, radiation and incineration at extreme temperatures.
  • In Humans – While there is no conclusive evidence that CWD can directly infect humans, the possibility remains a point of concern.

Quick Facts

  • Prion diseases, such as Creutzfeldt-Jakob disease (CJD) in humans and “mad cow disease” in cattle, have shown that they can cross the species barrier with devastating consequences.
  • The outbreak of mad cow disease in Britain, for instance, resulted in the slaughter of millions of cattle and led to 178 human deaths attributed to the human variant of the disease since 1995.
