  6. D. Pep-I
    Researchers from Indian Institute of Technology (IIT) Roorkee have discovered a small molecule named 'Pep-I' that exhibits good antiviral activity against chikungunya virus.
  7. Which of the following plans to launch a slew of important satellites?
    A. IISc
    B. ISRO
    C. NASA
    D. SpaceX
  8. B. ISRO
    Indian Space Research Organisation is gearing up to launch a slew of important satellites in the coming months. Some of these satellites are significant as they will help military keep an eye on our neighbors & safeguard our land & sea borders. ISRO will launch a dedicated satellite, Gsat-7A, for Indian Air Force & an advanced remote sensing satellite, Risat-2A, for surveillance purpose.
  9. A scientists from this country have formulated world's first ayurvedic drug to cure dengue.
    A. China
    B. India
    C. United Kingdom
    D. United States
  10. B. India
    Indian scientists have formulated world's first ayurvedic drug to cure dengue, which is likely to be available in the market by 2019. The first Ayurvedic drug to cure Dengue has been made with seven herbal ingredients which are in use in Ayurveda system of medicine. Pilot studies of this drug (in highly concentrated liquid form) which have proved the clinical safety and efficacy of the drug were already conducted by Central Council for Research in Ayurvedic Sciences (CCRAS), an autonomous body under the Ministry of AYUSH and Indian Council of Medical Research (ICMR's), regional research center in Belgaum in Karnataka.
  11. Who Launched Navigation Satellite IRNSS-1L recently?
    A. ISRO
    B. Japan Aerospace Exploration Agency
    C. NASA
    D. Space Studies Institute
  12. A. ISRO
    The Indian Space Research Organisation(ISRO) launched the Indian Regional Navigation Satellite System-1L, the eighth such satellite to be a part of a constellation. It was launched from the first launch pad at the Satish Dhawan Space Centre in Sriharikota, Andhra Pradesh. IRNSS-1L is expected to replace IRNSS-1A, the first of the seven navigation satellites that were rendered ineffective after its three rubidium atomic clocks failed. The seven satellites are part of the NavIC navigation satellite constellation.
  13. ISRO launched sounding rocket for atmospheric studies, what is the name of the rocket?
    A. Agni - IV
    B. Brahmos - II
    C. CartoSat
    D. RH300
  14. D. RH300
    The RH-300 MKII sounding rocket developed by IRSO's Vikram Sarabhai Space Centre (VSSC) was successfully launched from Thumba Equatorial Rocket Launch. The rocket was launched by VSSC under Sounding Rocket Experiment (SOUREX) programme for atmospheric studies. It utilizes this rocket to study the Equator.
  15. Who developed an atomic clock to be used in navigation satellites?
    A. Bhabha Atomic Research Centre
    B. Hindustan Aeronautics Limited
    C. Indian Space Research Organization
    D. Space Applications center
  16. C. Indian Space Research Organization
    The Indian Space Research Organization developed an atomic clock to be used in navigation satellites. It is supposed to measure precise location data. Once it successfully clears all tests, the desi atomic clock will be used in an experimental navigation satellite to test its accuracy and durability in space. At present, ISRO imports atomic clocks from European aerospace manufacturer Astrium (EAMA) for its navigation satellites. With the development of indigenous atomic clocks, the space agency sure gets a mark of technological advancement.
  17. The name of the new element that has been found with magnetic properties by the researchers of University of Minnesota is:
    A. Ruthenium (Ru)
    B. Titanium (Tu)
    C. Vibranium (Vb)
    D. Zylanium (Zy)
  18. A. Ruthenium (Ru)
    The name of the chemical element is Ruthenium (Ru). It is the fourth such element to have magnetic properties. So far, Iron (Fe), cobalt (Co) and Nickel (Ni) has these similar properties. They are ferromagnetic at room temperature. These elements can be used for their magnetic properties for better sensors, in the computer memory and logic industry and other devices using magnetic materials.
  19. ISRO scientists are developing a green propellant to replace which conventional rocket fuel?
    A. Hydrazine
    B. Liquid Hydrogen
    C. Liquid Nitrogen
    D. Liquid Oxygen
  20. A. Hydrazine
    Scientists at the Indian Space Research Organisation have reported progress in the development of an environment-friendly propellant to power satellites and spacecraft. The effort is to replace the conventional hydrazine rocket fuel, a highly toxic and carcinogenic chemical, with a greener propellant. ISRO has started working on propellant blend based on hydroxylammonium nitrate.
