It comes from the Mumbai-based company, Gangabishan Bhikulal Investment and Trading Limited (GBIT). What is the new gene? Diseases such as Zika, dengue and […]
RNA INTERFERENCE (RNAi)
RNAi is a gene silencing technology that inhibits protein synthesis in target cells using double-stranded RNA. Same result is achieved by Antisense technology through single-stranded RNA. RNAi technologies are now known to formulate drugs capable of reducing cholesterol levels by half. The technology also finds immense importance in treating acute viral infections like acquired immunodeficiency […]
CHINA’S GENE EDITING RULES
China has decided to introduce new Gene-editing rules. Rules require researchers to obtain prior approval from the government before undertaking clinical trials. Those found violating the rules will be punished and this includes a lifetime ban on research. The rules would also require all future trials to be approved by administrative authorities as well as ethical committees. Background Last year, […]
STEM CELL
Stem cells are the body’s raw materials — cells from which all other cells with specialized functions are generated. Under certain conditions in the body or a laboratory, stem cells divide to form more cells called daughter cells. These daughter cells either become new stem cells (self-renewal) or become specialized cells (differentiation) with a more specific function, such as blood cells, […]

INS VISHAL:
INS Vishal, also known as Indigenous Aircraft Carrier 2(IAC-2), is a planned aircraft carrier to be built by Cochin Shipyard Limited for the Indian Navy. It is intended to be the second aircraft carrier to be built in India after INS Vikrant(IAC-1), and the first supercarrier to be built in India. The proposed design of the second carrier class will be a new design, featuring significant changes […]
India’s Aircraft Carrier
Currently, Indian Navy opera only a single carrier, the 44,000-tonne INS Vikramaditya bought from Russia. INS Vikrant, is an indigenous aircraft carrier being built in Cochin Shipyard. It is a 40, 000 tonne carrier and expected to join service by 2021. INS Vishal, proposed to be India’s 2nd indigenous aircraft carrier has stalled since 2017 awaiting […]
INS Nilgiri
INS Nilgiri is the first ship of the Project-17A. Project 17A frigates is a design derivative of the Shivalik class stealth frigates with much more advanced stealth features and indigenous weapons and sensors. The P17A frigates incorporate new design concepts for improved survivability, sea keeping, stealth and ship manoeuvrability. These frigates are being built using integrated construction methodology.
INS Tarkash
It is a state-of-the-art stealth frigate of the Indian Navy. It is the 5th Talwar-class frigate constructed for the Indian Navy, built at the Yantar shipyard in Kaliningrad, Russia. It is equipped with a versatile range of weapons and sensors capable of addressing threats in all three dimensions.
