Bioterrorism is the use of bacteria, viruses, or germs to purposely harm large quantities of people or communities. These “weapons” are spread through air, water, or food sources. Bioterrorism is rare and is used to threaten people, governments, and countries. In bioterrorist attacks, usually only a small number of people may be injured or affected. … Read more
In plate tectonics, Convergent boundary is a region where two or more tectonic plates of the lithosphere move towards one another and collide. There are 3 types of Convergence: Ocean-Continental Continent-Continent Ocean-Ocean Features associated with ocean continental convergence: In this type of boundary, the oceanic lithosphere will always sub duct below the continental lithosphere. This … Read more
Gravitational Lensing is a natural phenomenon that magnifies light around galaxies. The phenomenon occurs when a huge amount of matter, such as a massive galaxy or cluster of galaxies, creates a gravitational field that distorts and magnifies the light from objects behind it, but in the same line of sight. This makes dim, faraway objects … Read more
A reusable launch system (RLS, or reusable launch vehicle, RLV) is a system capable of launching apayload into space more than once. Features RLV-TD is part of a series of technology demonstration missions that have been considered as a firststep towards realizing a Two Stage To Orbit (TSTO) fully re-usable vehicle. The configuration of RLV-TD … Read more
Robotics is a branch of engineering that involves the conception, design, manufacture, and operation of robots. This field overlaps with electronics, computer science, artificial intelligence, nanotechnology and bioengineering. Application in agriculture: Robots can be used to farming on a large scale, with efficiency and in lesser time. Helps in extensive farming. Robots make it … Read more
. Photonics is the science of light. It is the technology of generating, controlling, and detecting light waves and photons, which are particles of light. The characteristics of the waves and photons can be used to explore the universe, cure diseases, and even to solve crimes. Scientists have been studying light for hundreds of years. … Read more
As genetic research becomes more sophisticated, so does our ability to use plants and animals to develop new drugs or modify crops to meet food security needs. Often, in the search for new bio resources, researchers draw on local people’s traditional knowledge about the properties of a particular plant, animal or chemical compound. When researchers … Read more
Hydroponics, or growing plants in a nutrient solution root medium, is a growing area of commercial food production and also is used for home food production by hobbyists. Learn about the state-of-the-art techniques for producing food in a controlled, soilless setting. Major factors to ensure the successful hydroponics practice are as follows: Ensuring water quality … Read more
Cloning is the process of generating a genetically identical copy of a cell or an organism. Cloning happens often in nature—for example, when a cell replicates itself asexually without any genetic alteration or recombination. Prokaryotic organisms (organisms lacking a cell nucleus) such as bacteria create genetically identical duplicates of themselves using binary fission or budding. … Read more
A biometric system is a technology which takes an individual’s physiological, behavioral, or both traits as input, analyzes it, and identifies the individual as a genuine or malicious user. Basic Components of a Biometric System Input Interface (Sensors) It is the sensing component of a biometrics system that converts human biological data into digital form. … Read more
