Live vaccines are derived from “wild,” or disease-causing, viruses or bacteria. These wild viruses or bacteria are attenuated, or weakened, in a laboratory, usually by repeated culturing. For example, the measles virus used as a vaccine today was isolated from a child with measles disease in 1954. Almost 10 years of serial passage using tissue … Read more

Conventional breeding, especially of crops, livestock and fish, focuses principally on increased productivity, increased resistance to diseases and pests, and enhanced quality with respect to nutrition and food processing. Advances in cellular genetics and cell biology methods in the 1960s contributed to the so-called ‘green revolution’ that significantly increased varieties of staple food crops containing … Read more

An expedition, to promote the maritime heritage of India and spread awareness about Coastal Security amongst the coastal communities in Maharashtra, was launched by the Indian Navy on 05 January 2020 from the Naval Dockyard, Mumbai. The expedition extends from Arnala fort, Northernmost fort of Maharashtra to Sindhudurg fort, the southernmost fort of Maharashtra, covering … Read more

The DNA Technology (Use And Application) Regulation Bill, 2019 was introduced in the Lok Sabha. The bill which is also known as the DNA profiling bill, tries to check use of DNA technology to establish the identity of a person. According to the government, the DNA technology bill aims to establish the identity of missing … Read more

  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

DMH-11 is a Genetically Modified (GM) mustard hybrid. Hybrids are normally obtained by crossing 2 genetically diverse plants from the same species. The 1st-generation offspring resulting from it has higher yields than what either of the parents is individually capable of giving. But there is no natural hybridization system in mustard, unlike in, say, cotton, … Read more

Project Beehive was launched by the Army’s Corps of Electronics and Mechanical Engineers(EME) on September 1,2019. The project seeks to achieve greater automation of the Corps and connect all its workshops to an integrated smart network with real-time data analytics capabilities.The centralised network would allow Indian army to access data about any equipment across the … Read more

When there are changes in the condition like temperature, light or nutrients the symbiotic linkage between algae and zooxanthellae gets deteriorated, causing them to turn white. In coral bleaching the density of zooxanthellae decline and the concentration of photosynthetic pigment decline which lead to decline in color. 20% of the coral reefs have already been … Read more

IRS-1A, the first of the series of indigenous state-of-art operating remote sensing satellites, was successfully launched into a polar sun-synchronous orbit on March 17, 1988 from the Soviet Cosmodrome at Baikonur. The successful launch of IRS-1A was one of the proudest moments for the entire country, which depicted the maturity of satellite to address the … Read more

In zigzag kilns, bricks are arranged to allow hot air to travel in a zigzag path. The length of the zigzag air path is about three times that of a straight line, and this improves the heat transfer from the flue gases to the bricks, making the entire operation more efficient. In addition, better mixing … Read more
