Hot Spot is an image sensing system which makes use of infra-red cameras to find out if the batsman has nicked the ball. This technology was first introduced in cricket by a Melbourne based company, BBG Sports. Although two infrared cameras are enough, generally four infrared cameras are used to record the game continuously. The … 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

Reflex action is an immediate involuntary response to a stimulus. In an involuntary response, a sensory impulse on reaching central nervous system is itself returned to a specific effector as a motor impulse without neuronal analysis and integration. Reflex responses occur below the level of consciousness. Reflex actions are sudden and autonomic. For instance, if … Read more

Real time RT-PCR (reverse transcription–polymerase chain reaction) is now one of the most accurate laboratory methods for detecting, tracking, and studying the coronavirus. RT-PCR is a nuclear-derived method for detecting the presence of specific genetic material from any pathogen, including a virus. In order for a virus like the coronavirus to be detected early in … Read more

GP-write will include whole genome engineering of human cell lines and other organisms of agricultural and public health significance. Thus, the Human Genome Project-write (HGP-write) will be a critical core activity within GP-write focused on synthesizing human genomes in whole or in part. It will also be explicitly limited to work in cells, and organoids derived … Read more

An electric car is an automobile that uses an electric motor as it’s primary source of propulsion. Electric vehicles (EVs) use electrical energy which is stored in rechargeable batteries. One of the primary benefits of an EV is the lack of tailpipe emissions. The term electric vehicle (EV) is commonly used to refer to three main types of automotive drivetrains. These are Battery … Read more

Applications of tissue culture Rapid Clonal Propagation A clone is a group of individuals or cells derived from a single parent individual or cell through asexual reproduction. All the cells in callus or suspension culture are derived from a single explants by mitotic division. Therefore, all plantlets regenerated from a callus/suspension culture generally have the … Read more
