Context: Peru has declared health emergency over dengue outbreak.

About Dengue

  • Dengue fever is a mosquito-borne tropical disease that can provoke a high fever, headache, vomiting, muscle and joint pain, and sometimes death.
  • It is a viral infection transmitted to humans through the bite of infected mosquitoes.
  • Primary vectors: Aedes aegypti mosquitoes and, to a lesser extent, Ae. albopictus.
  • Serotypes: The virus responsible for causing dengue is called dengue virus (DENV).
    • Dengue infections are caused by four antigenically distinct serotypes, DENV-1, DENV-2, DENV-3 and DENV-4.
  • Severe dengue is a leading cause of serious illness and death in some Asian and Latin American countries.
  • Treatment: There is no specific treatment for dengue/severe dengue.


Solar Geo-engineering

Context: Scientists around the world agree that solar geo-engineering technique will be a possible key to tackle global warming.

About Solar Geo-engineering

  • Geo-engineering means manipulating the earth’s climate to lower its temperature in a bid to counter global warming.
  • Solar geo-engineering (solar radiation modification): It involves cooling the earth by radiating absorbed sunlight back into space.
    • It is a subset of geo-engineering.

Idea behind solar geo-engineering 

  • The temperature of the earth’s surface rises by absorbing heat energy from the sun (short wave radiation).
    • The warm surface of the earth emits part of this heat back as infrared radiation (long wave radiation). This outgoing radiation heats the atmosphere.
  • Greenhouse gases like carbon dioxide make it difficult for infrared radiation to escape the earth’s atmosphere, causing an imbalance between the incoming and outgoing energies.
    • As the total incoming energy exceeds the total outgoing energy, the surface of the earth warms up.
  • Solar geo-engineering aims at increasing the amount of heat radiated back into the space using artificial methods.
    • This will, in turn, reduce the temperature of the earth’s surface.

Types of Solar Geo-engineering 

  • Stratospheric Aerosol Injection (SAI): It includes spraying large quantities of tiny particles into the earth’s stratosphere to reflect sunlight and keep the earth cooler.
    • Compounds with reflective properties, like sulphur dioxides or finely powdered calcium carbonate, can be used as aerosols.
  • Marine Cloud Brightening: It proposes spraying sea salt into low-lying clouds to increase their brightness.
    • This could increase the concentration of droplets at the base of a cloud, which in turn will reflect more sunlight before it reaches the surface of the earth.

Anopheles Stephensi

Context: Anopheles Stephensi, a deadly malaria vector from Asia, has been detected in Kenya.

What is Anopheles stephensi?

  • Origination: Anopheles stephensi originated in Southeast Asia, West Asia and the Arabian Peninsula.
    • It was Africa first reported in Djibouti (2012).
    • Since then, this species has been expanding its geographic range in Ethiopia and Sudan, Somalia, and Nigeria.
  • Parasites: Anopheles stephensi is capable of transmitting both Plasmodium falciparum and P. vivax malaria parasites.
  • Spread: The species is reported to spread faster in different climatic conditions, especially in countries experiencing rapid urban development through devolution, like Kenya.
    • Unlike other main malaria-causing mosquito vectors that primarily breed in rural areas, Anopheles stephensi is highly adaptive and can thrive in urban environments.
    • Anopheles stephensi exploits several larval habitat types. The habitat types range from human-made water containers such as plastic tanks, cisterns, barrels, discarded tyres and plastic containers, to freshwater pools.


  • Malaria is an acute illness caused by Plasmodium parasites, which spreads to people through the bites of infected female Anopheles mosquitoes.
  • There are 5 parasite species that cause malaria in humans, and 2 of these species: P. falciparum and P. vivax pose the greatest threat.
  • P. falciparum is the deadliest malaria parasite and the most prevalent on the African continent.
  • P. vivax is the dominant malaria parasite in most countries outside of sub-Saharan Africa.


Chicago Convention

Context: The Union Cabinet has approved the ratification of three Protocols relating to amendments in the convention on International Civil Aviation (Chicago Convention), 1944.

What is the Chicago Convention?

  • The Convention on International Civil Aviation, also known as the Chicago Convention was drafted in 1944.
  • The agreement laid the foundation for the standards and procedures for peaceful global air navigation.
  • It set out as its prime objective the development of international civil aviation in a safe and orderly manner and such that air transport services would be established on the basis of equality of opportunity and operated soundly and economically.
  • As of March 2019, the Chicago Convention had 193 state parties, which includes all member states of the United Nations except Liechtenstein.
  • The Chicago convention set forth the purpose of International Civil Aviation Organization (ICAO).
    • ICAO is a specialized agency of the United Nations linked to Economic and Social Council (ECOSOC).

What are the amendments of the Chicago Convention ratified by the Cabinet?

  • Cabinet has ratified the following three protocols relating to amendments in the Chicago Convention:
    • Article 3: It refrains member States from resorting to the use of weapons against civil aircraft in flight.
    • Article 50(a): It raises the strength of the ICAO Council from 36 to 40
    • Article 56: It raises the strength of the Air Navigation Commission from 18 to 21.

What is the significance of ratification of these amendments by India?

  • The ratification would affirm India’s commitment to the principles enshrined in the Convention on International Civil Aviation.
  • The ratification would also provide better chances and opportunity for India to become more instrumental in matters pertaining to international civil aviation.


Revised Guidelines on MPLADs

Context: Recently, the Minister of State (Independent Charge) of the Ministry of Statistics and Programme Implementation (MoSPI) released the Revised Guidelines on Members of Parliament Local Area Development Scheme (MPLADS)-2023.

About MPLAD Scheme

  • The MPLADS is a Plan Scheme fully funded by Government of India, which was announced in December 1993.
  • Each year, MPs receive Rs. 5 crore in two installments of Rs. 2.5 crore each. Funds under MPLADS are non-lapsable.
  • Objective:
    • To enable MPs to recommend works of developmental nature with emphasis on the creation of durable community assets in the areas of drinking water, primary education, public health, sanitation and roads, etc. primarily in their Constituencies.
  • Implementation:
    • The Nodal District concerned is responsible for implementing the eligible works recommended by the Members of Parliament and maintaining the details of individual works executed and amount spent under the Scheme.
  • Functioning:
    • Lok Sabha MPs have to recommend the district authorities projects in their Lok Sabha constituencies, while Rajya Sabha MPs have to spend it in the state that has elected them to the House.
    • Nominated Members of both the Rajya Sabha and Lok Sabha can recommend works anywhere in the country.
  • Special focus:
    • MPs are to recommend every year, works costing at least 15 per cent of the MPLADS entitlement for the year for areas inhabited by Scheduled Caste population and 7.5 per cent for areas inhabited by S.T. population.

Context: A study in Japan has failed to find evidence if neutrinos are their own anti-particles.

About Neutrinos

  • Protons, neutrons, and electrons are tiny particles that form atoms.
  • The neutrino is also an elementary particle, but is not part of the atom. Such particles also exist in nature.
  • Neutrinos have a very tiny mass, no electric charge and a half spin. It interacts very weakly with other matter particles and hence difficult to detect.
  • Neutrinos are usually produced in high-energy processes such as within stars and supernovae. They are produced by particle accelerators and nuclear power plants on earth.

Applications of neutrinos:

  • Medical imaging
  • Detecting nuclear proliferation
  • Detecting mineral deposits
  • Faster global communication
  • Inter-stellar communication


  • Every elementary particle has an anti-particle. Both will destroy each other in a flash of energy, if they meet.
  • The electron’s anti-particle is the positron, which can be distinguished from each other as they have opposite charges.
  • Similarly, neutrinos have anti-neutrinos. However, neither neutrinos nor anti-neutrinos have electric charge, or any other properties to really differentiate them.
