  1. BIS-Care

Why in News

Recently, the Union Minister for Consumer Affairs, Food and Public Distribution has launched the Bureau of Indian Standard (BIS) Mobile App ‘BIS-Care’ and three portals namely the Standardization, Conformity Assessment and Training Portals of e-BIS for consumers.

  • BIS is the National Standard Body of India for the harmonious development of the activities of standardization, marking and quality certification of goods.

Key Points

BIS-Care App:

  • The app can be operated on any Android phone and is operational in Hindi and English
  • Consumers can check the authenticity of the ISI-marked and hallmarked products and lodge complaints using this app.
  • It is important to ensure that consumers are aware of the standards and quality products and help in eliminating the supply of sub-standard products.


  • e-BIS is an integrated portal covering all functions of BIS, enlisting the services of outside agencies for factory and market surveillance and development of mobile app-based and Artificial Intelligence (AI) enabled surveillance methods.

Other Steps Taken:

  • BIS has been playing an important role in the formulation of Quality Control Orders (QCO) to make the standards mandatory.
  • BIS is developing a portal on Consumer Engagement, which will facilitate the online registration of Consumer Groups, submission of proposals and approval thereof and complaint management.
  • BIS plans to implement One Nation, One Standard which is under examination and will be launched soon.
  • The Standard National Action Plan has been approved and important sectors of the economy for the development of standards have been identified. BIS developed Covid-19 standards for Cover-all and Ventilators and issued norms for grant of licence for N95 Masks, surgical masks and eye protectors which has resulted in an increased production of ISI-marked Personal Protection Equipment (PPE) items.
  • BIS has expanded and modernised its labs and has been creating testing facilities for drinking water and assaying of gold jewellery.

Way Forward

  • To achieve the objectives of Atmanirbhar Bharat Abhiyan and protect the interests of consumers, BIS had to further strengthen its efforts to formulate standards in the areas important for boosting India’s exports and regulating the import of cheap and sub-standard products.

  1. Risk of Interplanetary Contamination on Mars

Why in News

  • Recently, astrobiologists have expressed concerns about possible ‘interplanetary contamination’ on Mars as ambitious space missions are proliferating the space along with advances in commercial flight. Interplanetary contamination refers to biological contamination of a planetary body by a space probe or spacecraft, either deliberate or unintentional.

Key Points


  • In the past several missions have launched to Mars e.g. China’s Tianwen-1 which aims to land on the Red Planet’s surface, and the UAE’s Al Amal (Hope) which does not involve a landing, but an orbital mission that will study the Martian atmosphere.
  • The USA will soon launch its Perseverance mission, which would be the National Aeronautics and Space Administration’s (NASA) 10 successful Mars landing since
  • The Perseverance is a rover name for NASA’s Mars 2020 mission. It will seek signs of ancient life and collect rock and soil samples from the planet.
  • In the past, space missions have established physical contact with astronomical bodies such as comets and asteroids, and crewed missions have landed on the Moon.
  • since these bodies are known to be hostile to life, the possibility of their contamination has not been a pressing issue.

Type of Contamination:

  • There are two types of contamination i.e. forward and backward contamination.
  • Forward Contamination: It means the transport of Earth-based microbes to other celestial bodies.
  • Since, presence of liquid water was already discovered on Mars there is a chance that Mars has life and it is an ethical obligation on humanity to ensure that microbes from Earth do not disturb a possible Martian biosphere, allowing it to evolve in its own
  • Secondly, Earth-based organisms could spoil the integrity of the Red Planet’s samples that rovers want to study – a highly disruptive concept for scientists who are looking for signs of native Martian life.
  • Back Contamination: It is the transfer of extraterrestrial organisms (if they exist) into the Earth’s biosphere.
  • The scientists rule out back contamination with respect to Mars sample-return mission as their biochemistry would be markedly different from that on Earth.

Planetary Protection:

  • United Nations Outer Space Treaty of 1967: It serves as a defence mechanism against the militarisation of space and also requires nations to worry about contamination risks. Its 110 state parties include the USA, Russia, China, and India.
  • To ensure compliance with the Treaty, the Committee on Space Research (COSPAR) lays down a ‘planetary protection policy’ that aims to limit the number of microbes sent to other planets, as well as ensuring that alien life does not cause havoc on Earth.


  • Spacecraft Sterilisation: To prevent forward contamination, space missions take care to ensure that spacecraft are sterilised.
  • Previous Mars missions, such as NASA’s Viking landers of the 1970s, were all sterilised before being launched into space.
  • Containment: In the case of back contamination, sterilisation would not be an option–as this would ruin the extraterrestrial samples.
  • Containment would be the only option to break the chain of contact between possible alien microbes and life on Earth.


  1. New Research on Smallpox About its Origins

Why in News

  • Recently, a new study carried out by an international team of researchers provides fresh insight into the origins of the Smallpox disease. It suggested that the smallpox was in existence as early as during the Viking age in the 8 century CE.
  • The Viking Age was the period during the Middle Ages when the Norsemen (name given to the Scandinavian Vikings) undertook colonizing, conquest and trading throughout Europe, and reached North America in the 9 and 10 century.


  • About: Smallpox is a contagious disease, caused by the Variola Virus (VARV).
  • Transmission: It transmits through the droplets released from coughing, sneezing, and face to face contact with an infected person.
  • Eradication: One of the deadliest diseases known to mankind, it is also the only one to have been eradicated by vaccination.
  • In 1980, this was declared as completely eradicated after the global immunization campaign led by the World Health Organization (WHO) with the help of the smallpox vaccine.
  • Vaccine: The first effective vaccine was discovered by Edward Jenner in 1796.

Key Points

  • Origin: The origins of smallpox have always been unclear. Until now, the earliest confirmed case of the disease was found in the mummified remains of a 17 century Lithuanian child, even though written records suggest that it is much older.

Major Findings:

  • Finding Virus Sequence: The Variola virus sequence was recovered from 13 Northern European individuals including 11 dated to 600–1050 CE, overlapping the Viking Age.
  • Genetic Makeup: It also suggests that the genetic makeup of the viral strain recovered from the 11 individuals is different from the modern version which was eradicated in 1979-80.
  • Course of Evolution: It was suggested as a benign disease (less dangerous) considering that smallpox may have in the past been a mild. In the course of evolution, the active gene count of the virus is shown to have reduced due to mutation.
  • Therefore, the researchers speculated that smallpox became more deadly over time.

Implications of the New Research:

  • Information about the Viruses: The results of the study does not have any impact on the current spread of the Covid-19 pandemic.
  • However, it does provide important information on how a virus may become deadlier over time.

Ways of Spread:

  • These findings would help to understand the ways in which diseases have affected human populations in the past. The DNA evidence suggests that diseases such as plague and hepatitis B are associated with major prehistoric migrations — something that seems now to be true of variola too.
  • It would also help to seek answers of whether migrations brought the diseases to new areas or the emergence of disease triggered people to move.
