    From UPSC perspective, the following things are important:

    Prelims level: mWRAPR

    Mains level: NA

    The Indian Institute of Science (IISc.) led start-up has launched mWRAPR, a biological transport and storage medium for genomic sequencing labs, biobanks, and research labs handling biological samples for molecular analysis.

    mWRAPR

    • It is India’s first indigenous bio-sample kit, a biological transport and storage medium.
    • It would help in preserving genetic content in all types of biological samples, including microbiomes, saliva, cells, tissues, blood, body fluids, and fecal tubes.
    • It is the only Molecular Transport Medium to be manufactured in India that competes with sample stabilisation and transporting media of notable foreign brands.

    Significance

    • The disruptions in global supply chain limits accessibility to materials for molecular diagnostics.
    • India required to move to molecular tests (PCR/ RT-PCR test), but sample collection kits currently used were very cheap and not of molecular grade.
    • RNA WRAPR is the kind of molecular grade sample collection medium that India needs right now.

    What are Artificial Neural Networks (ANN)?

    Prelims Only | Science Tech | Mains Paper 3: Awareness in various sc and tech fields

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Artificial Neural Networks (ANN)

    Mains level: Artificial Intelligence

    This newscard is an excerpt from the original article published in TH.

    What are ANN?

    • The concept behind an ANN is to define inputs and outputs, feed pieces of inputs to computer programs that function like neurons and make inferences or calculations.
    • It then forwards those results to another layer of computer programs and so on, until a result is obtained.
    • As part of this neural network, a difference between intended output and input is computed at each layer and this difference is used to tune the parameters to each program.
    • This method is called back-propagation and is an essential component to the Neural Network.

    Setting up of ANNs

    • Instead of CPUs, Graphic Processing Units (GPU) which are good at performing massive parallel tasks can be used for setting up ANNs.
    • A few free ANN frameworks are TensorFlow, Keras, PyTorch and Theano.
    • These can be used for both normal Machine Learning tasks like classification or clustering and for Deep Learning/ANN tasks.

    Why called Neural Network?

    • Neuron is the building block of the brain and it inspired computer scientists from the 1950s to make a computer perform tasks like a brain does.
    • It is not a simple problem and the clue to its complexity is in the brain structure.

    Why ANN?

    Ans. Making an artificial brain

    • We need billions of artificial neurons if we were to build an artificial brain.
    • With the increase in computing power, mimicking billions of neurons is now possible.

    Popularity of ANNs

    • Data Science, used interchangeably with Machine Learning, is the computer technology that uses data to detect patterns.
    • Hand-written digit recognition is a good example of machine learning.
    • However, in order for the computer to do this task, large amounts of sample data need to be manually labelled as examples of images of digits.
    • The ANN mentioned above with its backpropagation does exactly this.
    • This is why ANNs have become hugely popular in the past decade. This approach of using neural networks of many layers to automatically detect patterns and parameters is called Deep Learning.

    What is Havana Syndrome?

    Prelims Only | Science Tech | Mains Paper 3: Conservation, Environmental Pollution & Degradation, Eia

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Havana Syndrome

    Mains level: NA

    A recent US intelligence report says that ‘Havana Syndrome’ —a collection of symptoms and related brain injuries, reported by some US officials could be caused by pulsed electromagnetic energy or close-range ultrasound.

    What is Havana Syndrome?

    • ‘Havana Syndrome’ is a colloquial name given to a set of symptoms such as dizziness, hearing loss, headaches, vertigo, nausea, memory loss and possible brain injuries.
    • It was first reported by 16 American Embassy staff and their family members in Havana, Cuba, in 2016-17.
    • There have been other instances of the phenomenon, which has mostly impacted US officials.

    What did the latest investigation find?

    • Such cases have been caused by pulsed electromagnetic energy in the radio frequency.
    • The results of the investigation did not point to who may have been behind the phenomenon, nor commented on their motivations.
    • A partially redacted report summary finds that the symptoms of AHI are “genuine and compelling.”

    What can be the other reasons?

    • Psychosocial factors alone do not explain the core characteristics, the report finds, although they may cause other incidents or contribute to long-term effects.
    • These other incidents could occur via hyper-vigilance or reactions to stress especially among individuals who are security-oriented.

  • Railway Reforms

    Fast-tracking Vande Bharat Express

    Prelims Only | Economics | Mains Paper 3: Infrastructure: Energy, Ports, Roads, Airports, Railways Etc.

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Vande Bharat Express

    Mains level: Highs speed railways in India

    Presenting the Union Budget for 2022-23, Finance Minister said 400 new energy-efficient Vande Bharat trains will be introduced in three years.

    What is Vande Bharat Express?

    • The Vande Bharat Express is a semi-high speed train designed, developed, and built by the Integral Coach Factory (ICF).
    • Presently there are only two Vande Bharat trains that are running — Delhi to Varanasi and Delhi to Katra.

    Key Features 

    • The current Vande Bharat trains have seating only in two classes — chair car and executive chair car. But Railways is planning to upgrade it.
    • The trains have fully sealed gangways for a dust-free environment, modular bio-vacuum toilets, rotating seats in Executive Class, personalized reading lights, automatic entry/exit doors with sliding footsteps, diffused LED lighting, mini pantry, and sensor-based interconnecting doors in each coach.
    • They are self-propelled trains that do not require an engine. This feature is called a distributed traction power system, which is increasingly becoming the norm the world over for passenger operations(Distributed power gives the train higher acceleration and deceleration compared to loco-hauled trains, which take a much longer time to reach top speed or to gradually come to a halt).
    • 400 trains announced by the Finance Minister carry a potential investment of Rs 50,000 crore over the next three years, because of different specifications and also, inflation.
    • The current Vande Bharat’s are being made at Rs 106 crore per trainset of 16 cars, at 2018 pricing.

    Benefits of Vande Bharat Trains

    1) Cuts Travel Time Drastically

    2) Energy Efficient

    3) Reduce Turnaround Time

    4) Faster Acceleration and Deceleration among others.

    Why High-speed rail projects are important for India?

    • Improve India’s GDP: According to a study conducted by the London School of Economics and Political Science and the University of Hamburg in 2008, cities that are connected to HSR systems tend to witness a rise in their gross domestic product (GDP) by at least 2.7 percentage points compared to their neighbors that do not have an HSR station. The reason for the differential was improved market access.
    • Role of the trains in India’s development: Being the third-largest network in the world under single management and
      with over 68,102 route km IR strives to provide a safe, efficient, competitive, and world-class transport system.
    • During FY21, IR carried 1.23 billion tonnes of
      freight and 1.25 billion passengers. In addition, despite COVID -19 pandemic revenue earning freight loading (excluding loading by Konkan Railway Corporation Ltd. (KRCL) was 1230.9 million tonnes in 2020-21 as compared to 1208.4 million tonnes during2019-20. Passengers originating were 1250 million in 2020-21 as compared to 8086 million in 2019-20- Economic Survey 2021-22. 
    • Spin-off effect: It is about Rs 40,000 crore business opportunity that would also create 15,000 jobs and several spin-off benefits and act as a stimulus for the development of satellite towns.
    • Boost to ‘Make in India’– it involves only about 15 percent import content which will further go down if production volumes increase.
    • Environmental Benefits: More rail traffic translates to less automobile traffic, and by extension, less highway and city street traffic congestion, reduced air pollution. In addition, less congestion means less wear and tear on the roadways, which means that they require fewer repairs.  According to the International Association of Railways (UIC), high-speed rail is eight times more energy-efficient than airplanes and four times more efficient than automobile use.
    • Social Benefits: High-speed rail can promote a sense of social cohesion among residents, by bringing distant populated areas closer together.
    • Global Experience: The High-Speed Railway has an economic multiplier effect. Since the introduction of the first Shinkansen (literally meaning ‘new main line’) in Japan in 1964, high-speed trains have proven to be an undeniable technological, commercial and popular success. Many countries like the UK, France, Germany, Spain, China, and most recently, the US have adopted the technology.

    Challenges faced by the High-Speed Rail Projects

    • Infrastructure Bottlenecks: India’s railway system is saddled with a two-pronged infrastructure deficit – aging infrastructure and the pace of new project execution struck by unforeseen circumstances related to socio-economic issues on land acquisition for new projects and escalating projects costs.
    • New Technologies: For instance, Hyperloop Transportation Technologies which proposes to make travel as fast as 760 miles per hour, investing a humongous capital on bullet trains seems like an outdated investment.
    • Political Will: The politics of Rail Bhavan and an unwillingness to accept the need for change have derailed the project execution.
    • Short of Investments: For instance, the estimated cost of Mumbai-Ahmedabad HSR is ₹1.1 lakh crore (US$17 billion) which is massively expensive. Though India receives funding from Japan (81%), the power demand and up-gradation of existing infrastructure will be more costly.
    • Social Conflict: Development along the corridor will lead to an increase in urbanization, the fight for resources, and social conflicts due to the labor influx of the workforce.
    • Legal Trouble: While farmers in Maharashtra are protesting on the ground, the farmers in Gujarat led by Gujarat Khedut Samaj (GKS)-  fighting a case in the Gujarat High Court against the land acquisition for the bullet train project.

    Way ahead

    • Stakeholders approach: Politics and Policy have to be in sync for the railway modernization. In order to achieve the target, Railways will have to pool in all resources and multiple stakeholders, including private players to deliver the propulsion system and also carry out the assembling. The Policymakers and administration should give priority to systematic sustainable development work- the convergence of jal, jungle, jameen(water-forest-land is an asset for the Adivasi community). 
    • Regular Monitoring: To ensure the induction of these trains in the shortest time possible, as envisaged by Indian Railways.
    • Technology Transfer: The government has to push for the technology transfer of HSR. This is because there is no mention of the transfer of technology anywhere in the agreement.

    Conclusion

    India aspires to become the third-largest economy in the next 25 years. It has already proven its prowess in the field of space and now is the time for furthering its international stature by joining the exclusive club of nations having a high-speed rail network, however, we should be careful not to confuse leapfrogging technology development with elitism, whether it is mobile phones, satellite launches, regional air connectivity, or high-speed rail. This high-speed rail project will therefore help the Indian Railways to become a global leader in scale, technology, and skill.

    What is ‘Z’ Category Security?

    Prelims Only | Security Issues | Mains Paper 3: Various Security Forces, Agencies & Their Mandates

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Categories of security

    Mains level: Need for security to politicians

    A noted Parliamentarian from Hyderabad has rejected the ‘Z’ category security by the Central Armed Police Forces (CAPF) accorded to him.

    Security Provisions in India

    • In India, security is provided to high-risk individuals by the police and local government.
    • The level of security needed by any individual is decided by the Ministry of Home Affairs, based on inputs received from intelligence agencies which include the IB and R&AW.
    • Individuals such as PM, home minister, and other officials such as the National Security Advisor generally get security cover because of the positions they occupy.
    • In addition to this, persons who are believed to be under threat also receive security cover.

    What is ‘Z’ Category Security?

    In India, the category covers are X, Y, Y-plus, Z, Z-plus, and SPG (Special Protection Group).

    • X Category: The protectee gets one gunman. Protectees in the Y category have one gunman for mobile security and one (plus four on rotation) for static security.
    • Y Plus category: It receives the cover of two gunmen (plus four on rotation) for mobile security, and one (plus four on rotation) for residence security,
    • Z Category: It has six gunmen for mobile security and two (plus 8) for residence security. They get 10 security personnel for mobile security, and two (plus 8) for residence security.
    • Z Plus Category: It is provided by National Security Guard commandos whereas the other category of security is provided by the Delhi police or the ITBP or CRPF personnel.

    What about Special Protection Group (SPG) Cover?

    • The SPG cover is meant only for the PM and his immediate family.
    • After Indira Gandhi was assassinated by her own security guards in 1984, the Rajiv Gandhi government decided to create a special cadre of security personnel for the PM.
    • In March 1985, following the recommendations of a committee set up by the Home Ministry, a special unit was created for this purpose under the Cabinet Secretariat.
    • This unit, initially called the Special Protection Unit, was renamed as Special Protection Group in April 1985.

  • ISRO Missions and Discoveries

    Chandrayaan-3 set for launch in August

    Prelims Only | Science Tech | Mains Paper 3: Awareness in various sc and tech fields

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Chandrayaan-3

    Mains level: Not Much

    ISRO plans to execute the Chandrayaan-3 mission in August this year.

    What is Chandrayaan-3 Mission?

    • The Chandrayaan-3 mission is a follow-up of Chandrayaan-2 of July 2019, which aimed to land a rover on the lunar South Pole.

    Chandrayaan-2: A quick recap

    • Chandrayaan-2 consisted of an Orbiter, Lander and Rover, all equipped with scientific instruments to study the moon.
    • The Orbiter would watch the moon from a 100-km orbit, while the Lander and Rover modules were to be separated to make a soft landing on the moon’s surface.
    • ISRO had named the Lander module as Vikram, after Vikram Sarabhai, the pioneer of India’s space programme, and the Rover module as Pragyaan, meaning wisdom.

    Utility of the Orbiter

    • The Orbiter part of the mission has been functioning normally. It is carrying eight instruments.
    • Each of these instruments has produced a handsome amount of data that sheds new light on the moon and offers insights that could be used in further exploration.

    Inception of Chandrayaan 3

    • The subsequent failure of the Vikram lander led to the pursuit of another mission to demonstrate the landing capabilities needed for the Lunar Polar Exploration Mission proposed in partnership with Japan for 2024.

    Its design

    • The lander for Chandrayaan-3 will have only four throttle-able engines.
    • Unlike Vikram on Chandrayaan-2 which had five 800N engines with a fifth one being centrally mounted with a fixed thrust.
    • Additionally, the Chandrayaan-3 lander will be equipped with a Laser Doppler Velocimeter (LDV).

    Back2Basics: Chandrayaan-1 Mission

    • The Chandrayaan-1 mission was launched in October 2008 was ISRO’s first exploratory mission to the moon, in fact to any heavenly body in space.
    • The mission was designed to just orbit around the moon and make observations with the help of the instruments onboard.
    • The closest that Chandrayaan-1 spacecraft came to the moon was in an orbit 100 km from its surface.

  • Forest Conservation Efforts – NFP, Western Ghats, etc.

    [pib] Definition of Forest in India

    Prelims Only | Enviro & Biodiversity | Mains Paper 3: Conservation, Environmental Pollution & Degradation, Eia

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Definition of Forests

    Mains level: Not Much

    The Union Ministry of Environment, Forest & Climate Change has informed about the criteria used to define forest in India.

    Defining Forests universally

    • As per the Conference of Parties (CoP) 9-Kyoto Protocol, the forest can be defined by any country depending upon the capacities and capabilities of the country.
    • Forest- Forest is defined structurally on the basis of
    1. Crown cover percentage: Tree crown cover- 10 to 30% (India 10%)
    2. Minimum area of stand: area between 0.05 and 1 hectare (India 1.0 hectare) and
    3. Minimum height of trees: Potential to reach a minimum height at maturity in situ of 2 to 5 m (India 2m)

    India’s definition of Forests

    The definition of forest cover has clearly been defined in all the India State of Forest Report (ISFR) and in all the International communications of India.

    • The forest cover is defined as ‘all land, more than one hectare in area, with a tree canopy density of more than 10 percent irrespective of ownership and legal status.
    • Such land may not necessarily be a recorded forest area. It also includes orchards, bamboo and palm’.

    Classification of forest cover

    In ISFR 2021 recently published has divided the forest cover as:

    1. Inside Recorded Forest Area: These are basically natural forests and plantations of Forest Department.
    2. Outside Recorded Forest Area: These cover mango orchards, coconut plantations, block plantations of agroforestry.

    Back2Basics: Forest Classification in India

    The Forest Survey of India (FSI) classifies forest cover in 4 classes.

    • Very Dense forest: All lands with tree cover (including mangrove cover) of canopy density of 70% and above.
    • Moderately dense forest: All lands with tree cover (including mangrove cover) of canopy density between 40% and 70%.
    • Open forests: All lands with tree cover (including mangrove cover) of canopy density between 10% and 40%.
    • Scrubs: All forest lands with poor tree growth mainly of small or stunted trees having canopy density less than 10%.

  • Wildlife Conservation Efforts

    Places in news: Godavari Estuary in Coringa Wildlife Sanctuary (CWS)

    Prelims Only | Enviro & Biodiversity | Mains Paper 3: Conservation, Environmental Pollution & Degradation, Eia

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Ramsar Convention, Coringa WLS

    Mains level: Not Much

    Godavari Estuary in Coringa Wildlife Sanctuary (CWS) is facing due ignorance despite meeting all nine criteria of Ramsar Convention.

    Godavari Estuary

    • The estuary, including 235.70 sq. km Coringa Wildlife Sanctuary (CWS), is one of the rarest eco-regions on the earth.
    • It is also home to India’s second-largest mangrove cover after the Sundarbans.
    • The CWS is inhabited by 115 endangered fishing cats (Prionailurus viverrinus), Olive Ridley turtles, Indian smooth-coated otter, and saltwater crocodiles.

    What are the nine criteria laid out by Ramsar Convention?

    • Criterion 1: “it contains a representative, rare, or unique example of a natural or near-natural wetland type found within the appropriate biogeographic region.”
    • Criterion 2: “it supports vulnerable, endangered, or critically endangered species or threatened ecological communities.”
    • Criterion 3: “it supports populations of plant and/or animal species important for maintaining the biological diversity of a particular biogeographic region.”
    • Criterion 4: “it supports plant and/or animal species at a critical stage in their life cycles, or provides refuge during adverse conditions.”
    • Criterion 5: “it regularly supports 20,000 or more waterbirds.”
    • Criterion 6: “it regularly supports 1% of the individuals in a population of one species or subspecies of waterbird.”
    • Criterion 7: “it supports a significant proportion of indigenous fish subspecies, species or families, life-history stages, species interactions and/or populations that are representative of wetland benefits and/or values and thereby contributes to global biological diversity.”
    • Criterion 8: “it is an important source of food for fishes, spawning ground, nursery and/or migration path on which fish stocks, either within the wetland or elsewhere, depend.”
    • Criterion 9: “it regularly supports 1% of the individuals in a population of one species or subspecies of wetland-dependent non-avian animal species.”

    Back2Basics: Ramsar Convention

    • The Convention on Wetlands of International Importance (better known as the Ramsar Convention) is an international agreement promoting the conservation and wise use of wetlands.
    • It is the only global treaty to focus on a single ecosystem.
    • The convention was adopted in the Iranian city of Ramsar in 1971 and came into force in 1975.
    • Traditionally viewed as a wasteland or breeding ground of disease, wetlands actually provide fresh water and food and serve as nature’s shock absorber.
    • Wetlands, critical for biodiversity, are disappearing rapidly, with recent estimates showing that 64% or more of the world’s wetlands have vanished since 1900.
    • Major changes in land use for agriculture and grazing, water diversion for dams and canals, and infrastructure development are considered to be some of the main causes of loss and degradation of wetlands.

  • Blockchain Technology: Prospects and Challenges

    What are Virtual Digital Assets?

    Prelims Only | Economics | Mains Paper 3: Government Budgeting

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Virtual Digital Assets

    Mains level: Taxing crypto assets

    Recently, The Central Board of Direct Taxes (CBDT) issued detailed guidelines on the Tax Deducted at Source (TDS) rule for Virtual Digital Assets (VDAs) such as cryptocurrencies .

    What are Virtual Digital Assets?

    • To define the term “virtual digital asset”, a new clause (47A) is proposed to be inserted into section 2 of the Act.
    • A virtual digital asset is proposed to mean any information or code or number or token (not being Indian currency or any foreign currency):
    1. Generated through cryptographic means or otherwise
    2. Providing a digital representation of value that is exchanged with or without consideration with the promise or representation of having inherent value
    3. Functions as a store of value or a unit of account and includes its use in any financial transaction or investment, but not limited to, investment schemes
    4. Can be transferred, stored, or traded electronically.
    • Non-fungible token (NFT) and; any other token of similar nature are included in the definition.

    Why tax them?

    • Popularity: Virtual digital assets have gained tremendous popularity in recent times and the volumes of trading in such digital assets have increased substantially.
    • Growing market: Further, a market is emerging where payment for the transfer of a virtual digital asset can be made through another such asset.
    • Increased transactions: There has been a phenomenal rise in such transactions and the magnitude and frequency of these transactions have made it imperative to provide for a specific tax regime.
    • Prevalence of gifting: The gifting of virtual digital assets is also a popular mode of exchange.

    Key takeaways from the FM’s speech

    • The bill provides for the definition of virtual digital assets which is wide enough to cover emerging digital assets including NFT, assets in metaverse, cryptocurrencies, etc.
    • This recognition of digital assets under income tax is NOT akin to granting legal status.
