Nanotechnology has the potential to completely revolutionise all the three key aspects of healthcare sector-Diagnosis, prevention and Treatment. It can completely change the healthcare sector for the next generation. Nanotechnology will help medical professionals in today’s most excruciating medical issues, such as repairing of damaged organs, diagnosis and treatment of cancer cells, removal of obstruction … Read more DMPQ: Applications of Nanotechnology in Health care sector. Discuss ( SCIENCE)

  Miniaturisation of the transistor size. Smaller, faster and better transistors may mean that soon your computer’s entire memory may be stored on a single tiny chip. Using magnetic random access memory (MRAM), computers will be able to “boot” almost instantly. MRAM is enabled by nanometer‐scale magnetic tunnel junctions and can quickly and effectively save … Read more DMPQ: Application of nanotechnology in the field of electronics and IT application. Discuss. (SCIENCE)

Captive breeding is the process of breeding animals outside of their natural environment in restricted conditions in farms, zoos or other closed facilities. The choice of individual animals that are to be part of a captive breeding population, and the mating partners within that population, are controlled by humans. Advantages: • Endangered animals have a … Read more DMPQ: What is captive breeding programme? Discuss its advantage(SCIENCE)

  Nanotechnology is improving the efficiency of fuel production from raw petroleum materials through better catalysis. It is also enabling reduced fuel consumption in vehicles and power plants through higher-efficiency combustion and decreased friction.  carbon nanotube “scrubbers” and membranes to separate carbon dioxide from power plant exhaust. Development of wires containing nano tube that will … Read more DMPQ: . Application of nanotechnology in the field of Energy application. (SCIENCE)

Low Pollution: Nuclear power also has a lot fewer greenhouse emissions. It has been determined that the amount of greenhouse gases have decreased by almost half because of the prevalence in the utilization of nuclear power. Nuclear energy has the least effect on nature since it doesn‘t discharge any gasses like methane and carbon dioxide, … Read more DMPQ: Discuss the points in favour of nuclear energy.

:  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 DMPQ: Nitrogen pollution is more dangerous than carbon pollution. How nitrogen affects our ecosystem. (Science)

.   CRISPR stands for Clustered regularly interspaced short palindromic repeats it is in the series of molecular scissors which is used for deletion, insertion and replacement of genome to achieve the desired result. It is latest technology of gene editing. Cas-9 is an enzyme. It use a synthetic guide RNA to introduce a double strand … Read more DMPQ: What is CRISPR-Cas9 and explain the process involved in using it. (Science)

It is a technology to bring the changes in the phenotype(the way we appear) by altering the genome. The insertion of foreign gene and thus creating new gene is called recombinant gene. The technology involved in the process is called rDNA technology. Steps in the rDNA technology are: Identification Of donor DNA and Plasmid DNA. … Read more DMPQ: What is recombinant DNA technology? Mention the steps involved in rDNA technology? (Science)

Hydroponics is a subset of hydroculture, the method of growing plants without soil, using mineral nutrient solutions in a water solvent.With hydroponics the plants are grown in an inert growing medium and a perfectly balanced, pH adjusted nutrient solution is delivered to the roots in a highly soluble form. Advantages of hydroponics: No soil is … Read more DMPQ: What is hydroponics? What are its advantages? (Science)What is hydroponics? What are its advantages? (Science)
