Important Science Questions SSC CGL,UPSC Board May Ask In Prelims

We have been trying to bring you some IMPORTANT SCIENCE QUESTIONS SSC CGL,UPSC May asks in prelims as these questions were in the news.And our team has tried our best,hope being a reader you will surely appreciate out efforts.


  1. Light Detection and Ranging (LIDAR)
  • It’s a method of remote sensing which make use of light to measure variable distances (range) to the earth. It provides highly accurate data on topology (surface).
  • It is composed of a Laser, a GPS receiver and a scanner.
  • In 2015 Telengana Government used it to survey River Godavari.
  • Currently Telengana Government is planning to use the same technology for high resolution maps of the state. This will help them in various engineering and other project planning.
  1. Bionic Leaf 2.0
  • Bionic leaf uses the sunlight to split water molecules into oxygen and hydrogen.
  • Hence this technology has ability to convert solar energy into biomass with 10% efficiency which is higher than even photosynthesis.
  • It has been invented by Harvard University scientists.

  1. KBr Banned
  • Potassium Bromate has been banned as food additives after a CSE (centre for Science & Environment) test proved that KBr in breads may cause cancer.
  • KI (Potassium Iodate) has also been referred for tests as they might also be carcinogenic.
  1. Maltitol for bone construction
  • Indian Institute of Science (IISc) have developed a method to use maltitol (derived from the carbohydrate Maltose) for reconstruction of bones.
  • This can be used for fractures instead of metal rods.
  • Traditional use of rods prevents growth of bones in infants but Maltitol is poised to remove the disadvantage.
  1. Bio-Ink in 3D Printer
  • This will allow 3D printer to print complex living tissue for implants with the help of bio-ink.
  • Bio-ink has two polymers, a natural (from seaweed) and one sacrificial.
  • It can be used in knee or hip surgery and many other bone or cartilage implants. It uses patient’s own stem cell.
  1. Dark Sky Reserve
  • China has installed Dark Sky Reserve for astronomical observation in Ngari, Tibet.
  1. Nano Mission
  • The Department of S&T has come up with guidelines best suited for safe handling of Nano materials.
  • It was introduced by GoI in 2007 with an allocation of Rs. 1000 crore for 5 years then.
  • Applications of Nano Technology:

i)Treatment of waste water

  1. ii) Food packaging, cosmetics and sunscreen.

iii) Desalinization of water.

  1. iv) Treat diseases and other vast medical uses.
  2. Zika
  • Cause: Aedes Mosquito
  • Symptoms : Muscle weakness, Headache, nerve problems or paralysis
  • The DNA Vaccine: GLS-5700, the vaccine for zika virus has completed phase I of tests on animals. This will also be tested on Humans soon.
  1. PSLV-C34
  • ISRO launched its 35th consecutive successful PSLV launch vehicle into earth’s orbit carrying a record (for ISRO) 20 satellites from Satish Dhawan Space Centre, Sriharikota.
  • ISRO’s last big satellite launch was in 2008 when it launched 10 satellites in 1 rocket.
  • It carried satellites from USA, Germany, Canada and Indonesia. It also launched 3 satellites from India.
  • Cartosat-2, one of the three satellites will have uses in geology, disaster management, border management etc. The other two were made by college students.
  • This launch open doors for India in new avenues of $300 Billion space market in which India is still a small player.
  • With recent testing of Reusable Launch Vehicle, the cost of launch may be further reduced by 80%.

  1. Draft on Drones (Civilian Application)
  • It was announced by DGCA (Director General of Civil Aviation) for civil UAV (Unmanned aerial Vehicle) operations.
  • Civilian use of UAV/drones has huge potential on safety but also poses few security threats.
  • Airspace over any cities is already crowded and unregulated use of drones may cause threat of air collisions.
  • Karnataka Police Depart is first to use Drones. They have at present 20 trained police officers for handling of drones, which can be a sure shot question and very IMPORTANT SCIENCE QUESTIONS SSC CGL,UPSC board may ask in prelims.
  1. DRDO tests Advanced Air Defense (AAD)
  • Ashwin, an indigenously made new AAD tested from Abdul Kalam Island (Wheeler Island) by DRDO.
  • It was launched from a mobile launcher, targeted towards nuclear cpapble-Danush ballistic missile at endo-sphere altitude of 25-40 kms.
  • India started building BMD (Ballistic Missile Defense) from 1999 after Kargil war when Pakistan attacked under the protection of nuclear umbrella.
  • India already has six regiments of Russian S-300 and negotiating for another five S-400s.
  • India’s BMD shield is two-tiered:
  1. Prithvi Air Defense / Pradyumna Ballistic Missile: For destroying missile in rage of 50-80 kms.
  2. Advanced Air Defense / Ashwin interceptor missile: For incoming missiles of range 20-40 kms.
