Recognizing the crucial role of technology and innovation in economic development, India’s policy makers have taken several initiatives to promote science, technology and innovation. Various schemes have been launched to attract, nurture and retain young researchers and women scientists in the field of scientific research. Some important achievements in the field of science and technology … Read more

Cloud seeding is the process of spreading either dry ice, or more commonly, silver iodide aerosols, into the upper part of clouds to try to stimulate the precipitation process and form rain. There are three cloud seeding methods– Hygroscopic cloud seeding disperses salts through flares or explosives in the lower portions of clouds. The salts grow in size as … Read more

Genetic recombination is the process by which two DNA molecules exchange genetic information, resulting in the production of a new combination of alleles. In eukaryotes, genetic recombination during meiosis can lead to a novel set of genetic information that can be passed on to progeny. Most recombination is naturally occurring. During meiosis in eukaryotes, genetic … Read more

  Medical microbiology basically deals with the study of microorganisms that are both beneficial and harmful to both human and animal majorly. Branches of medical microbiology include Virology, Bacteriology, Parasitology and Mycology etc. Following are some of the major important features of the medical microbiology. The major importance of medical microbiology is that it helps … Read more

. Today, satellites are launched into orbit by multi-staged satellite launch vehicles that can be used only once (expendable). These launch vehicles carry oxidiser along with the fuel for combustion to produce thrust. Launch vehicles designed for one time use are expensive and their efficiency is low because they can carry only 2-4% of their … Read more

1) GSAT-7A:    GSAT-7A with a lift-off mass of 2250 kg, is a geostationary satellite carrying communication transponders in Ku-band. The Satellite is built to provide communication capability to the users over the Indian region. It was launched by the GSLV-F11 launchpad.  It is ISRO’s 7th flight with indigenous upper stage cryogenic engine.  The four liquid … Read more

While proposing the double helical structure for DNA, Watson and Crick had immediately proposed a scheme for replication of DNA. The scheme suggested that the two strands would separate and act as a template for the synthesis of new complementary strands. After the completion of replication, each DNA molecule would have one parental and one … Read more

Many somatic plant cells, including some fully differentiated types (e.g. leaf mesophyll),provided they contain intact nuclear, plastid and mitochondrial genomes, have the capacity to regenerate into whole plants. This phenomenon is totipotency.Totipotent cells from plants have been used in tissue-culture techniques to produce improved plant materials that are pathogen-free and disease-resistant. Totipotent cells fromanimals are … Read more

Rocket engine needs enormous amount of thrust to escape Earth’s gravitational pull. However the chemicals used for engines are Hydrogen and Oxygen (Hydrogen used as a fuel, while Oxygen as a oxidiser) that produces a good thrust, found in Earth in the form of gas. Carrying hydrogen and oxygen in their gaseous form will require … Read more
