Quantum Technology in India

Quantum Technology Part of: GS Prelims and GS-III- S&T  (Editorial plus) What is this technology? Quantum computers perform calculations based on the probability of an object's state before it is measured - instead of just 1s or 0s - which means they have the potential to process exponentially more data compared to classical computers. Classical computers carry out logical operations using the definite position of a physical state. These are usually binary, meaning

Genome Sequencing

Genes Gene is a sequence of DNA or RNA that codes for a molecule that has a function.  They are made of DNA and is a subdivision of DNA. They are packed in Chromosomes. Genes contain the bio-information that defines any individual. Physical attributes like height, skin or hair colour, more subtle features and even behavioural traits can be attributed to information encoded in the genetic material. A genome is the DNA or sequence of genes in a cell. Human geno

Analysis of Indian Genes

Analysis of Indian Genes What is the news? Recently, the results from the computation analysis of the 1029 sequenced genomes from India were published in the scientific journal, Nucleic Acid Research. The analysis has found that out of 55,898,122 single nucleotide variants in India 18,016,257 (32.23%) variants are unique and found only in the samples sequenced from India. This emphasizes the need for an India centric population genomic initiative. The analysis was carried out by C


PLACID Trials Recently, the PLACID Trial, a multicentre randomized controlled trial, has shown that the use of convalescent plasma (CP) as a therapeutic for Covid-19 patients showed no positive effects and did not improve the outcome of the patients.

It has thus influenced even the basic values of life, and given to civilization a new vitality and a new dynamism.” The resolution said the aim of the scientific polic

How Neutrinos help in the death of massive stars?

How Neutrinos help in the death of massive stars? Many stars, towards the end of their lifetimes, form supernovas - massive explosions that send their outer layers shooting into the surrounding space. Most of the energy of the supernova is carried away by neutrinos – tiny particles with no charge and which interact weakly with matter. Researching the mechanisms of the so called Type II supernovas, a team from IIT Guwahati has come up with new insights into the part played by n

Syn gas

Synthesis gas (syngas) is a combustible mixture of hydrogen and carbon monoxide, often containing carbon dioxide and methane. It's primarily used to produce methanol or ammonia, and can also be used as a fuel. Syngas is derived from carbon-containing feedstocks like biomass, natural gas, heavy oil, and coal.

FLip mutation

JN.1 subvariant has a mutation in its spike protein, L455S, also called a “FLip” mutation. L455S and L455F are called “FLip” mutations because they switch the positions of amino acids F and L on the spike protein, increasing their transmissibility. This type of mutation is performed we use binary crossover.

Ground frost

Ground frost is a covering of ice that forms on objects, trees, or the ground when their surfaces are below the freezing point of water. It can also refer to a temperature that drops below freezing at or near ground level and damages vegetation. Ground frost can occur when the ground cools faster than the air. It can also occur when water vapor directly deposits on objects and trees with surfaces colder than 0°C.

DFRP and Nuclear Energy

Prime Minister dedicated to the nation, indigenously developed Demonstration Fast Reactor Fuel Reprocessing Plant (DFRP) at the Indira Gandhi Centre for Atomic Research (IGCAR), Kalpakkam, Tamil Nadu. The plant - It is a pilot for the bigger facility that would come up to reprocess the fuel that would come out of the two more 500 MW Prototype Fast Breeder Reactors (PFBR) that would come up later. A fast breeder reactor is one, which breeds more material for a nuclear fission reac

The program aims to promote robust clinical studies in priority areas of Ayurveda with Ayurveda academic institutions/hospitals across the country through mutual collaboration.

Fog Pass Device

A Fog Pass Device is a GPS-based navigation device that helps train loco pilot navigate through dense fog. It provides on-board real-time information (Display as well as voice guidance) to Loco Pilots. It gives information regarding location of fixed landmarks such as Signal, Level Crossing gate (Manned & Unmanned), Permanent Speed Restrictions, Neutral Sections etc.


Starlink is a satellite internet network operated by SpaceX, an American aerospace company. It provides coverage to over 70 countries and aims to provide high-speed internet coverage to every part of the world. It also aims to provide global mobile phone service after 2023.

North India's 1st Biotech Industrial Park

North India’s 1st industrial biotech park inaugurated in Jammu and Kashmir’s Kathua recently. Biotech Parks offer facilities to scientists and small and medium-sized enterprises (SMEs) for technology incubation, demonstration, and pilot plant studies. The parks are established to facilitate product advancement and innovation through the development of biotechnology industrial clusters.


The Union Cabinet Chaired by the Prime Minister of India has approved the overarching scheme ‘PRITHvi Vigyan’ (PRITHVI). Implemented by – Ministry of Earth Sciences (MoES). The research & development and operational (services) activities of MoES are carried out by 10 Institutes of MoES. Timeline – 2021-26, at an overall cost of Rs. 4,797 crore. It encompasses 5 ongoing sub-schemes namely ACROSS – A

Square Kilometre Array (SKA) Observatory

India had decided to formally join the Square Kilometre Array (SKA) project, an international scientific collaboration working to build the world’s largest radio telescope. What is SKA? SKA – It will be the world's biggest and most advanced radio telescope ever constructed. It will not be a single large telescope, but a collection of thousands of dish antennas operating as a single unit. SKA Observatory Convention – The interna

Light Detection and Ranging – LiDAR

Lidar, which stands for Light Detection and Ranging, is a remote sensing method that uses light in the form of a pulsed laser to measure ranges (variable distances) to the Earth. These light pulses—combined with other data recorded by the airborne system — generate precise, three-dimensional information about the shape of the Earth and its surface characteristics. A lidar instrument principally consists of a laser, a scanner, and a specialized GP

Thirty Meter Telescope (TMT)

Recently, an official delegation from the Department of Science and Technology visited Mauna Kea to discuss “challenges” to the Thirty Meter Telescope (TMT) project. Thirty Meter Telescope (TMT) It has been conceived as a 30-metre diameter primary-mirror optical and infrared telescope that will enable observations into deep space. It is proposed as a joint collaboration involving institutions in the U.S., Japan, China, Canada, and India. It will b

Light-emitting diodes (LEDs)-FACTS

Light-emitting diodes (LEDs) succeed the incandescent bulbs and fluorescent lamps of previous centuries as the world’s light-source of choice. About Light-Emitting Diodes A diode is an electronic component which has two points of contact, or terminals, called its anode and cathode. A diode’s primary purpose is to allow current to flow in only one direction. An LED is a semiconductor device which emits light when electric current flows through it. It
