Shaurya missile


Shaurya missile launched.

      WHY IN NEWS:

  • Recently, a successful trial of the nuclear-capable Shaurya missile was conducted by India.
  • Also, Brahmos land attack cruise missile was tested a few days before this testing.



Shaurya is a land variant of short-range Submarine Launched Ballistic Missile (SLBM) K-15 Sagarika.

  • It has a range of at least 750 kilometers.
  • It is a surface-to-surface tactical missile.
  • It is capable of carrying payloads of 200 kg to 1000 kg.

These ballistic missiles belong to the K missile family .

  • It is codenamed after late Dr. APJ Abdul Kalam – which are launched from Arihant class of nuclear submarines.
  • The missile is less vulnerable to anti-ballistic missile defence systems due to its high maneuverability.


  • The K family of missiles are primarily Submarine Launched Ballistic Missiles (SLBMs).
  • India has also developed and successfully tested multiple times the K-4 missiles from the family which has a range of 3500 km.

The early development trials of K-15 and K-4 missiles had begun in the early 2010s.

  • K-5 and K-6 with ranges of 5000 and 6000 km are also under development.


These have been indigenously developed by Defence Research and Development Organisation (DRDO).

  • The development of these missiles began in the late 1990s as a step towards completing India’s nuclear triad.
  • Nuclear triad is the capability of launching nuclear weapons from land, sea and air-based assets.
  • Because these missiles are to be launched from submarines, they are lighter, smaller and stealthier than their land-based counterparts – the Agni series of missiles.
  • Agni Missiles are medium and intercontinental range nuclear capable ballistic missiles.

      IASbhai WINDUP: 


  • The capability of SLMBs has great strategic importance in the context of achieving a nuclear triad.

Especially in the light of the ‘no first use’ policy of India which acts as a deterrent.

  • These submarines can not only survive a first strike by the adversary but also can launch a strike in retaliation thus achieving Credible Nuclear Deterrence.

SC against involuntary narco tests


SC against involuntary narco tests : Nation in shock

      WHY IN NEWS:

People protesting against the Hathras incident, in New Delhi on Sunday.
SYLLABUS COVERED: GS 2 : 3: Policies and Interventions


In 2010 judgment, it said such tests were an affront to dignity and liberty



  • Involuntary administration of narco or lie detector tests is an “intrusion” into a person’s “mental privacy”, a Supreme Court judgment of 2010 has held.
  • The consequences of such tests on “individuals from weaker sections of society who are unaware of their fundamental rights and unable to afford legal advice” can be devastating, the court said.

It may involve future abuse, harassment and surveillance, even leakage of the video material to the Press for a “trial by media.

  • Such tests are an affront to human dignity and liberty, and have long-lasting effects.
  • “An individual’s decision to make a statement is the product of a private choice and there should be no scope for any other individual to interfere with such autonomy,” the apex court had held.

      IASbhai WINDUP: 


  • The judgment in Smt. Selvi vs State of Karnataka observed that involuntary administration of these scientific tests was “sufficient to constitute a custodial environment”.
  • It amounted to a “restraint on personal liberty”.
  • “Law disapproves of involuntary testimony .It violates the prescribed boundaries of privacy.
  • It most certainly comes into conflict with the ‘right against self-incrimination’.

Forcible interference with a person’s mental processes is not provided for under any statute.

Xoo bacterium


Moving towards a vaccine to reduce yield loss due to diseases in rice

      WHY IN NEWS:

Dr Tayi Lavanya and her team is developing new disease control strategies which they can use as vaccines that activate the rice immune system.

MINISTRY? :-Ministry of Science & Technology
SYLLABUS COVERED: GS 3:Health:Diseases


A scientist has uncovered the mechanism by which a bacterium called Xoo (Xanthomonas oryzaepv. oryzae) that causes a serious bacterial leaf blight disease in rice interacts with rice plant and cause disease.


  • The research group is working to identify and develop few molecules which are derived from either the Xoo bacterium or from the infected rice cell walls.

The team is developing new disease control strategies which they can use as vaccines.

  • This can activate the rice immune system and provide resistance to rice plants from subsequent infections by pathogens.


  • Xanthomonas oryzaepv. oryzae, or commonly known as Xoo infection, cause huge yield losses to rice cultivation throughout the world.

Treatment of rice with cellulase, a cell wall degrading enzyme secreted by Xoo induces rice immune responses and protects rice from subsequent infections by Xoo.

  • The team carried out biochemical and functional studies on plant cell wall degrading enzymes secreted by Xoo.
  • This has provided key insights into the mechanisms by which the Xoo pathogen interacts with rice plant and cause disease.

      IASbhai WINDUP: 

We may be close to a vaccine to boost the immune system of rice !

  • Currently, the group is working on a cellulase protein secreted by Xoo.
  • This cellulase protein has the features of a typical vaccine as it is a potent elicitor of rice immune responses.
  • Pre-treatment of rice plants with this protein provides resistance to rice against subsequent Xoo infection.
