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.
IMPORTANT SCIENCE QUESTIONS SSC CGL and Technology [Part- 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.
- 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.
- 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.
- 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.
- 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.
- Dark Sky Reserve
- China has installed Dark Sky Reserve for astronomical observation in Ngari, Tibet.
- 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
- ii) Food packaging, cosmetics and sunscreen.
iii) Desalinization of water.
- iv) Treat diseases and other vast medical uses.
- 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.
- 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%.
- 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.
- 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:
- Prithvi Air Defense / Pradyumna Ballistic Missile: For destroying missile in rage of 50-80 kms.
- Advanced Air Defense / Ashwin interceptor missile: For incoming missiles of range 20-40 kms.
