CGS-7: Science-Tech Bits

CTR-17 and CTR-20

Researchers from the Rajiv Gandhi Proudyogiki Vishwavidyalaya (RGPV), Bhopal have applied for the US patent of the discovery of the anti-cancer molecules code-named CTR-17 and CTR-20.These two anti-cancer molecules are discovered from the turmeric and they are found to be killing the cancel cells without any side effects.The two molecules are effective against multi-drug resistant cancer cells and studies have also shown that the molecules increase the life-span of lab animals affected with the tumours.

National Biotechnology Development Strategy (NBDS) 2015-2020

Union Government has unveiled National Biotechnology Development Strategy (NBDS) 2015-2020 to establish India as a world-class bio-manufacturing hub.

Double Sulphitation Method

SO2 is added in sugar manufacturing process because at initial stage it converts the basic character of treated sugar cane juice to neutral in character. During second time treatment of juice with SO2, it is used as a bleaching agent and leads to purification and responsible for white colour of sugar. The added sulphur leads to formation of hydrogen sulphides (H2S) which is a poisonous gas and is responsible for producing foul smell in industry.

World’s first biologically powered chip

Scientists from Columbia Engineering have harnessed the molecular machinery of living systems to power an integrated circuit. In living systems, adenosine triphosphate (ATP) transfers the energy from where is generated to where it is consumed in the cell. Scientists have isolated this biological process and used it to power an integrated circuit. To achieve this, a CMOS IC chip is connected with an artificial lipid bilayer membrane containing ATP-powered ion pumps.

Rotavirus vaccination project

Himachal Pradesh has become the first state in the country to start Rotavirus vaccination project under the Universal Immunisation Programme (UIP). The project is based on the analogy of the polio vaccine and will help in controlling the deaths amongst small children due to Diarrhoea.

Biodiesel for Trains in SWR Zone

The South Western Railways (SWR) Zone with headquarters in Hubli, Karnataka has introduced biodiesel for trains, operating under its zone. Recently, the SWR’s first train Hubballi- Bengaluru Janshatabdi Express powered by five per cent biodiesel blended with High Speed Diesel was flagged off from Hubli. The main aim of the initiative is to reduce greenhouse gases (GHGs) emission and carbon footprint and also to make fuel consumption more efficient. To meet its biodiesel demand, SWR zone has set up Biodiesel filling centres at Hubli, Bengaluru and Hospet. In next one year all the 13 railway depots within the zone will have their own filling units and the biodiesel blending will be gradually increased to ten percent.

Inactivated Polio Vaccine (IPV) injection

The Union Government has launched inactivated polio vaccine (IPV) injection as part of the global polio endgame strategy in New Delhi. It was launched as part of India’s next step in Universal Immunization Programme (UIP) to fight against polio virus in the country.

Regional Centre for Biotechnology Bill, 2015

The Union Cabinet chaired by the Prime Minister Narendra Modi has given its approval for introduction of Regional Centre for Biotechnology Bill, 2015. The bill aims for establishment of a Regional Centre for Biotechnology (RCB) in Faridabad, Haryana and provide a legal status to the Centre.

Dengvaxia: first Dengue fever vaccine

Mexico Government has approved world’s first-ever Dengue fever vaccine branded as Dengvaxia for the public use. Key facts Dengvaxia has been manufactured by French pharmaceutical manufacturer Sanofi Pasteur.Philippines became the first Asian country to approve the sale of the world’s first ever dengue vaccine Dengvaxia in the country.


ISRO’s Polar Satellite Launch Vehicle PSLV-C29 has successfully launched six commercial satellites from Singapore into their orbit from Satish Dhawan Space Centre (SDSC) at Sriharikota, Andhra Pradesh. Of the six satellites, the 400 kg earth observation satellite called TeLEOS-1 is the main passenger for the PSLV rocket. Thus, the mission is called TeLEOS mission by ISRO.TeLEOS-1 is Singapore’s first commercial earth observation satellite designed and developed by ST Electronics. The other five co-passenger satellites are VELOX-C1 (123 kg), VELOX-II (13 kg), Kent Ridge-1 (78 kg), Galassia (3.4 kg) and Athenoxat-1. This is the 32nd flight of PSLV and 11th flight of the launch vehicle in ‘core-alone’ configuration, which is without the use of solid strap-on motors.

Gene Modification to fight Malaria

Scientists have genetically modified malaria-causing mosquito Anopheles gambiae species to fight the deadly disease of malaria. They have genetically modified the mosquito species so that they carry a modified gene disrupting egg production in female mosquitoes.
