  • The Karolinska Institute confers the prize for physiology or medicine and the Swedish Academy confers the prize for literature.
  • The Norwegian Nobel Committee based in Oslo confers the prize for peace.



  • A MoU was signed between ISRO and the Federal Space Agency of Russia ROSCOSMOS on joint activities in the field of the human spaceflight programme Gaganyaan.
  • If successful, India would be the fourth nation to send a human in space after the US, Russia and China.
  • Gaganyaan is India’s maiden human spaceflight programme scheduled for completion by 2022.
  • GSLV Mk-III launch vehicle, which has the necessary payload capability for this mission, will be used to launch Gaganyaan.

China’s Artificial Moon

  • China has planned to launch an artificial moon over the city of Chengdu, in Sichuan province, by 2020 to provide an alternative means of street lighting and save on electricity.
  • As per preliminary reports the artificial moon would be a mirror orbiting Chengdu at a height of 500 km. It would reflect the sun’s light at night, and supplement street lighting in Chengdu, which has a population of 1.6 million.
  • China is not the first country to try beaming sunlight back to Earth. In the 1990s, Russian scientists reportedly used giant mirrors to reflect light from space in an experimental project called Znamya or Banner.

Andhra, West Bengal withdraws CBI power to investigate

  • Section 5 of the Delhi Special Police Establishment Act (DSPEA) gives powers to the CBI over all areas in the country, but Section 6 states that without the consent of the state concerned, it cannot enter that state’s jurisdiction.
  • Apart from Mizoram, West Bengal and Andhra Pradesh, the agency has consent in one form or the other for carrying out investigations across the country.

Kilogram re-defined

  • At the 26th CGPM, General Conference on Weights and Measures, in Versailles, Paris more than 60 nations came together to vote unanimously for a new system that redefines the kilogram.
  • kilogram, the ampere (electrical current), the kelvin (thermodynamic temperature) and the mole (amount of a substance) were redefined at the conference.
  • The kilogram has been defined since 1889 by a shiny piece of platinum-iridium kept in a special glass case, the International Prototype of the Kilogram (IPK), also known as Le Grand K (The Big K). It is housed at the headquarters of the International Bureau of Weights and Measures (BIPM), just outside Paris.
  • Now the kilogram will be defined by the Planck Constant, denoted as h, is a physical constant that is the quantum of action, which relates the energy carried by a photon with the frequency of its electromagnetic wave.

SpiNNaker (Spiking Neural Network Architecture) Supercomputer

  • designed and built to work in the same way a human brain does, has been fitted with its landmark one-millionth processor core and has been switched on for the first time.
  • The SpiNNaker is capable of completing more than 200 million actions per second, with each of its chips having 100 million transistors.
  • Biological neurons are basic brain cells present in the nervous system that communicate primarily by emitting spikes of pure electro-chemical energy.
  • Neuromorphic computing uses large scale computer systems containing electronic circuits to mimic these spikes in a machine.
  • One billion neurons is one per cent of the scale of the human brain, which consists of just under 100 billion brain cells, or neurons, which are all highly interconnected via approximately one quadrillion synapses.

European Human Brain Project

  • The HBP Flagship was launched by the European Commission’s Future and Emerging Technologies (FET) scheme in October 2013

HysIS (Hyper Spectral Imaging Satellite)

  • ISRO has successfully launched the PSLV-C43 mission that carried HysIS (Hyper Spectral Imaging Satellite) as part of its payload.

GSAT 29 launched

  • ISRO’s GSAT-29 communication satellite recently launched successfully by the second developmental flight of Geosynchronous Satellite Launch Vehicle Mark III (GSLV Mk III-D2) from the Satish Dhawan Space Centre, Sriharikota.

GSAT 29 – weighing 3,423 kg at lift-off, GSAT-29 is the heaviest satellite to be launched from India.

GSLV Mk III –  three-stage heavy lift launch vehicle developed by ISRO. The vehicle has two solid strap-ons, a core liquid booster and a cryogenic upper stage.

Earth BioGenome Project

  • with an ambitious objective was recently announced to map the entire genome of every known animal, plant, fungus and protozoan on earth.
  • A decade-long experiment to map the genomes of roughly 1.5 million species — all the complex life forms known to man

China unveils heavenly palace space station ‘Tiangong’

  • a replica of its first permanently crewed space station, which would replace the international community’s orbiting laboratory and symbolises the country’s major ambitions beyond Earth.

The International Space Station – a collaboration between the US, Russia, Canada, Europe and Japan, has been in operation since 1998 but is due to be retired in 2024.

INS Arihant

  • INS Arihant, India’s first nuclear ballistic missile submarine, has completed its first deterrence patrol.
  • With the induction of INS Arihant, India is ready with its nuclear triad – the capability of firing nuclear weapons from land, air and sea.
  • India has now become part of an elite club of countries – Russia, the US, China, France and the UK that possess nuclear ballistic missile submarines – the only non-Permanent member of UNSC having a sea-based nuclear deterrent.


India’s Nuclear Doctrine

  • made in 2003.
  • The basic principle of India’s nuclear doctrine is “No First Use”.
  • Nuclear weapons will only be used in retaliation against a nuclear attack on Indian Territory or on Indian forces anywhere.

10th Indian Ocean Naval Symposium

  • 26 of the 32 countries that constitute the membership of the Indian Ocean Naval Symposium (IONS) are participating in the 10th edition of the event that commenced in Kochi
