Vaccine hesitancy reflects concerns about the decision to vaccinate oneself or one’s children. There is a broad range of factors contributing to vaccine hesitancy, including the compulsory nature of vaccines, their coincidental temporal relationships to adverse health outcomes, unfamiliarity with vaccine-preventable diseases, and lack of trust in corporations and public health agencies. Vaccine hesitancy is … Read more

  Seeker Technology :The seeker technology is a critical technology that determines the accuracy of a missile. So far, the seeker technology had come from Russia.   The technology is a closely guarded secret.  Mastering it is a significant milestone in missile technology and would reduce import dependence.  The seeker was developed by Research Centre Imarat … Read more

A fuel cell is a device which produces electric energy, through a chemical reaction. Fuel cells use positively charged ion(Hydrogen) and an oxidising agent (oxygen).There are many types of fuel cells, but they all consist of a cathode,an anode, and an electrolyte that allows positively charged( hydrogen) ions to move between the two sides of … Read more

Uranium is one of the fissile material which is used for power generations. But All isotopes are not categorised as fissile. The certain minimum standards have to be met to qualify as fissile material: It should be able to sustain the chain reaction. It should have a high probability of fission when bombarded with slow/fast … Read more

Pathogenic Bacteria These bacteria cause great losses to plant and animal popula­tion by causing several diseases. Reduction of Soil Fertility Some facul­tative anaerobic bacteria are available mostly in the oxygen deficient soil which reverse the nitrifying process, thereby causing the loss of a part of its combined nitrogen. They break down the nitrates in a … Read more

. Important tools which come under Biotechnology are as follows: Genetic engineering Genetic engineering is the process of using recombinant DNA (rDNA) technology to alter the genetic makeup of an organism. Traditionally, humans have manipulated genomes indirectly by controlling breeding and selecting offspring with desired traits. Genetic engineering involves the direct manipulation of one or … Read more

Steps of photosynthesis  Carbon dioxide in the atmosphere enters the plant leaf through stomata, i.e., minute epidermal pores in the leaves and stem of plants which facilitate the transfer of various gases and water vapor.  Water enters the leaves, primarily through the roots. These roots are especially designed to draw the ground water … Read more

. Metagenomics is the study of a collection of genetic material (genomes) from a mixed community of organisms. Metagenomics usually refers to the study of microbial communities. “Metagenomics” is the two words “meta” and “genomics”. So genomics is obtaining the DNA sequence, but meta implies that we’re doing it of many organisms together. And metagenomics … Read more

:  Nitrogen is the most abundant gas in the atmosphere and it is in inert form. But when it converts into reactive form like ammonia, nitrous oxide and nitrogen di oxide, it become dangerous for the ecosystem in many ways. Nitrogenous gases also play an important role in global climate change. Nitrous oxide is a particularly … Read more
