Govt. report flags lapses in “filovirus study” among Nagaland bats

Read More
What is the News?

The government of India has concluded that there have been lapses in the conduct and protocols followed for the filovirus study of bats in Nagaland.

What was the filovirus study about?
  • Researchers from India, China and the US had conducted a study in Nagaland on bats and humans carrying antibodies to deadly viruses like Ebola.
    • From India, the National Centre for Biological Sciences(NCBS) and the Tata Institute of Fundamental Research(TIFR) participated in the study.
  • Findings: The study found the presence of filovirus reactive antibodies in human and bat populations in northeast India. Hence, the study suggested that Bats in South Asia act as reservoir hosts of a diverse range of filoviruses.

Note:

  • Filoviruses belong to a virus family called Filoviridae and can cause severe hemorrhagic fever in humans and nonhuman primates.
  • So far, three varieties of this virus family have been identified: Cuevavirus, Marburgvirus and Ebolavirus.
Significance of this filovirus study:
  • The findings of the study became significant given the debate over the origins of COVID-19 worldwide and the handling of bat samples at the Wuhan Institute laboratory.
  • However, scientific experts and officials have made it clear that the Nagaland bat study on filoviruses (Ebola and Marburg) was in no way related to the coronavirus(SARS) studies at Wuhan.
Government of India’s inquiry into filovirus study:
  • The Government of India had ordered an inquiry in 2020 into this study. The inquiry investigated how the scientists were allowed to access live samples of bats and bat hunters (humans) without due permission.
  • The inquiry concluded that there have been lapses in the conduct and the protocols followed by the study. The lapses include:
    • Firstly, the study did not have the approval of the Indian Council of Medical Research(ICMR)
    • Secondly, the Bangalore based National Centre for Biological Sciences (NCBS) is not equipped in terms of Biosafety and Biosecurity for testing samples.

How to Prevent Misuse of Synthetic Biology?

Read More

Synopsis: Synthetic biology is a double-edged sword. It is highly prone to misuse, thus there is an urgent need for international measures for monitoring and verification.

Background:
  • Synthetic biology is a revolutionary technology. It can help us manipulate biological organisms and processes for human betterment, especially in treating diseases, by re-engineering cells.
  • Till now there is no clarity over the origin of Coronavirus, but it is clear that bio-weapons can be made in labs.

However, the preparedness of nation-states and weak global security arrangements are not sufficient in dealing with the misuse of synthetic biology.

What are the concerns associated with the misuse of synthetic biology?
  1. Firstly, its misuse has national and global security implications.
    • In 2014, for instance, the U.S. Department of Defense categorised synthetic biology as one of the six disruptive basic research areas.
  2. Secondly, there is always a chance of accidental leaks of experimental pathogens.
    • Various factors such as insufficiently trained staff, inadequately safeguarded facilities, and lack of proper protocols followed during experiments might trigger the leak in the future.
  3. Thirdly, poor regulation of bio-weapons even after growing military interest in synthetic biology.
    • Bio-weapons are recognised as the ‘weapon of mass destruction’ (WMD) but nothing is done by the international community.
    • Nuclear weapons have received maximum safety and security due to attention given by the institutional arrangements.
  4. Fourthly, the attack through bioweapons takes time to show its impact. In that case, it is difficult to ensure accountability.
    • For example, in case of attacks carried out by state actors against the enemy, it would be difficult to pin responsibility as the incubation period is high, and the pathogen can be modified to hide its origin.

Why Biological and Toxin Weapons Convention is not effective in dealing with the misuse of synthetic biology?

  1. Firstly, the Biological and Toxin Weapons Convention (BTWC) of 1972 has no implementing body and does not have a verification clause.
    • Also, it has not clearly laid down rules and procedures to guide research.
  2. Secondly, the dilemma in Article 1 of the BTWC.
    • Bio-weapons are banned, but research for medical and bio-defence purposes is allowed for peaceful purposes.
    • But the issue is that there is a thin line between bio-defense research and bio-weapons research.
  3. Thirdly, the report of an ad-hoc group to negotiate a protocol to ensure transparency was not accepted by the member states of BTWC. The Ad Hoc Group was set up in 1994 at the Fifth BTWC Review Conference in 2001.
  4. Lastly, the traditional distinction at the international institutional level between biological weapons (BTWC) and diseases (domain under the World Health Organization) is not useful anymore.
Why India is more vulnerable to bio-weapon attack?
  • Firstly, lack of preparation and poor infrastructure.
    • India is not having a strong disease surveillance system.
    • The poor state of the healthcare system was visible during a pandemic.
  • Secondly, there is a multiplicity of bodies and the absence of an empowered coordinating body, which makes coordination difficult.
    • For instance, the implementation of biosafety guidelines is the responsibility of the Science and Technology Ministry and the Environment Ministry.
    • However, labs dealing with biological research are set up under the Indian Council of Medical Research and the Indian Council of Agricultural Research, which are under the Ministries of Health and Agriculture, respectively.
  • Thirdly, the traditional ministry-wise separation is not useful in the case of zoonotic diseases as it requires one health approach”.
  • Lastly, India has porous borders with ill-trained border control institutions, and they are not prepared for defending against pathogens.
Way forward:
  • There is a need for cooperation between health specialists and bio-weapons/defence specialists.
  • The November 2021 BTWC review conference must review advances in the field and address the thinning line between biotechnology research and bio-weapons research.

Single dose of vaccine can’t control Delta Variant: Global Study on vaccines

Read More
Synopsis:

The data from clinical trials and post-vaccination study on vaccines shows that the Dominant delta variant of Covid-19 can’t be easily controlled by a single dose of vaccine. The countries must administer two doses of vaccine and should reduce the time gap between them.

Background:
  • The WHO has recently given a new classification to SARS-CoV-2 variants of interest (VOI) and variants of concern (VOC) on the basis of Greek letters. The objective was to create easy-to-pronounce and non-stigmatising labels for VOI and VOC.
  • However, the established nomenclature systems for naming and tracking of SARS-CoV-2 genetic lineages by GISAID, Nextstrain and Pango will remain in use for scientific research.
  • The new classification is as follows:
    • VOC B.1.1.7 will be called Alpha Variant. It was the earliest documented in the United Kingdom (September 2020).
    • VOC B.1.351 will be called Beta Variant. It was the earliest documented in South Africa (May 2020).
    • VOC P.1 will be called Gamma Variant. It was the earliest documented in Brazil (November 2020).
    • VOC B.1.617.2 will be called Delta Variant. It was the earliest documented in India (October 2020).
About the Delta Variant:
  • It was first identified in Maharashtra and is believed to be responsible for the severe second wave in India.
  • It has now spread to most parts of India and also been identified in many other countries.
  • The rapid expansion has induced the WHO to graduate it from a “variant of interest” (VOI) to a “variant of concern” (VOC) category.

Scientists have undertaken various studies to address 3 major questions surrounding the delta VOC – 

  1. Is it more infectious than the prevalent virus?
  2. Is it more lethal than the previous virus?
  3. Does the delta variant is more resistant to the effect of vaccines? 
Data shown by various studies on vaccines:

Read Also :-What are “Variants of Concern” (VoC)?

  • Results of Study conducted by Indian SARS-CoV-2 Genomic Consortia (INSACOG) and the National Centre for Disease Control (NCDC):
    • The Delta variant is the “prime reason” behind the second wave, though the wave may have been initiated by the Alpha variant.
    • The Delta Variant has become dominant even in Britain, where scientists have recently noted that it is 50% more infectious than the Alpha variant.
  • Results of study on vaccines conducted by Public Health England:
    • A single dose of the AstraZeneca vaccine provided 33% efficacy against the Delta variant, while it was 51% against the Alpha variant.
    • The second dose improved the efficacy to 60% against the Delta variant and to 66% against the Alpha variant.
    • Further, two doses of Pfizer-BioNtech vaccine provided much higher levels of protection than two doses of the AstraZeneca vaccine.
  • Results of a British study on vaccines published in Lancet Journal:
    • Merely 32%of the vaccinated individuals had adequate antibody levels against the Delta variant after the first dose of the Pfizer vaccine. It was 25% against the beta variant.
    • The antibody levels rose after the second dose. However, they were far below the levels obtained against the initial variant of the Covid-19 virus.
  • Results of a study on vaccines conducted by the Pasteur Institute, France:
    • The Delta variant showed reduced response to both the vaccines (Pfizer and Astrazeneca). It was resistant to neutralisation by some monoclonal antibodies targeting the Spike protein.
    • The study concluded that a single dose of the Astrazeneca vaccine will not display optimal protection against the delta variant.

Lessons learnt from the various study on vaccines:

  • First, the Delta variant is the most infectious variant in circulation. However, there is not much convincing evidence to prove it is more deadlier than the previous variants.
  • Second, vaccines have diminished efficacy against the delta variant. Further, a single dose of either the AstraZeneca or the Pfizer-BioNTech vaccine does not provide adequate protection against the Delta variant.
  • Third, a shortened dosing interval is recommended to deal with the Delta variant. Britain has already reduced the interval to 8 weeks from earlier 12 weeks.

Mixing Covid-19 vaccines: Benefits and Concerns

Read More

What is the news?

India plans to conduct research on Mixing Covid-19 vaccines. This is to investigate if it can immunize people using a “mix and match” of different Covid-19 vaccines.

What does mixing of vaccines mean?
  • Mixing of vaccines means following up one dose of a particular vaccine with a second dose of a different vaccine. In scientific terms, this is called “heterologous” immunization.
Have vaccines been mixed before Covid-19?
  • Mixing and matching of vaccines have been tested for decades, especially for viruses like Ebola. However, most combinations had initially been restricted to vaccines that use the same technology.
  • In India, combinations of rotavirus vaccines have also been used and tested out.
Reasons for mixing Covid-19 vaccines:
  • Better Immune Response: Several scientists believe that using a different vaccine for the second dose could potentially boost the immune response against the virus.
    • Example: Viral vector vaccines like Covishield use a modified and weakened chimpanzee ‘adenovirus’ (common cold virus). But using the same adenovirus could make the vaccine less effective the second or third time around. That is why Sputnik V uses two different adenoviruses to deliver the spike protein’s code to our bodies.
  • Protection against mutations and variants: Mixing and matching vaccines of different technologies such as a viral vector vaccine followed up with an mRNA vaccine-like Pfizer’s might encourage our immune system to build a wider response.
    • Such combinations could also potentially provide wider protection against certain mutations or variants of the SARS-CoV-2 virus.
  • Can cover up the shortages of Vaccines: Current Covid-19 vaccine production cannot sufficiently cater to the existing demand, resulting in stock-outs. Hence, in the short term, mixing solves the shortage of vaccines problem.
  • Safety Concerns: Countries like Germany, UK have halted the use of the AstraZeneca vaccine in younger age groups due to concerns of rare blood clots. Here, mixing and matching will allow the completion of immunization while ensuring safety.

Also Read: India needs an effective vaccine policy

Concerns:

  • Many unknowns: The Covid-19 vaccines in use have received restricted emergency use permissions. Hence, questions about how safe it is to mix and match and whether the approach can prompt a better immune response are still being answered.
  • Untested Combinations: Some vaccines like Covaxin have not even been administered in a mix and match scenario. Hence, more research needs to be conducted.
  • Differences in Vaccines: There are complexities in mixing vaccines which includes
    • differences in the shelf life of these vaccines
    • shipment and storage conditions
    • Some vaccines may have more side effects or may not work.
  • Side effects: Studies such as the Com-COV trials have shown that some combinations like AstraZeneca with Pfizer vaccines could lead to an increase in side effects.

Cryptocurrency in India – Lessons from other Countries

Read More

Synopsis: No legal classification of cryptocurrency in India should not be the reason for its ban. There are some international examples, from where India can adopt some ways to deal with Cryptocurrencies.

Introduction 

El Salvador became the first country in the world to adopt bitcoin as legal tender. This shows the rising global trend of accepting cryptocurrencies with all their associated risks. Almost all countries are permitting the growth of the cryptocurrency market subject to certain safeguards.

However, India is still thinking about whether to prohibit or regulate cryptocurrencies.  Globally, there is an inclination towards regulations that recognizes the freedom of choice of people for using a medium of exchange other than a central bank-backed fiat currency.

How has India responded to the crypto business so far?

The cryptocurrency market in India has advanced in a mainly unrestrictive regulatory space since the first recorded cryptocurrency transaction in 2010. 

  • Firstly, between 2013 and 2018, the government’s response to the rise of virtual currencies was cautionary. It alerted users to the potential risks posed by cryptocurrency transactions. These concerns arose from its potential use in criminal activities such as money laundering, terrorist financing, and tax evasion.
  • Secondly, in April 2018, RBI effectively banned cryptocurrency trading. However, the Supreme Court in 2020 overturned this ban.
  • The court said that RBI can take other regulatory measures instead of an outright ban through which risks associated with cryptocurrency trading can be curbed. 
  • Now, the draft Cryptocurrency and Regulation of Official Digital Currency Bill, 2021 has been introduced. The draft Bill plans to criminalize all private cryptocurrencies while also laying down the regulatory framework for an RBI-backed digital currency.

Minister of State for Finance stated in the Parliament that regulatory bodies do not have a legal framework to directly regulate private cryptocurrencies. Then, how these currencies should be regulated?

What are the lessons that India could learn from other countries?

India can take a few lessons from the U.K., Singapore, and the U.S.  UK. They have categorized cryptocurrency as property. This has made the way for cryptocurrencies to be included within a regulated legal framework in the country’s economy.

  • The U.K. wants to regulate the working of crypto-businesses while still imposing some restrictions to protect the interests of investors.
  • There is no precise legal classification of cryptocurrency in Singapore, but the flexibility of cryptocurrency transactions to the contract law framework of the country has been resolutely recognised and there is now a legal framework for cryptocurrency trading.
  • In the U.S., the authorities are taking an open approach, It led to the taxing and regulation of trade-in cryptocurrency.
Conclusion 
  • These approaches are country-specific and cannot be directly implemented in India. However, the global regulatory attitude towards cryptocurrencies gives valuable insights into the other ways to achieve balanced regulation.
  • In India, the absence of an existing legal classification of cryptocurrency should not be the basis to ban its use. The government should use this as an opportunity to allow private individuals the freedom to harness a powerful new technology with appropriate regulatory standards.

Factors Affecting Growth of Block Chain technology in India

Read More

Synopsis:  There are many positive benefits in utilising blockchain technology. However, regulatory uncertainties in Policymaking have impeded the growth of Blockchain technology in India.

 Background
  • Satoshi Nakamoto created the most popular cryptocurrency, Bitcoin, in 2008, as a fully decentralised, peer-to-peer electronic cash system.
  • Since then, Bitcoins have seen phenomenal growth in market value. For instance, Bitcoin, which was traded at just $0.0008 in 2010, commands a market price of $65,000 this April.
  • Many newer coins were introduced since Bitcoin’s launch, and their cumulative market value touched $2.5 trillion. Their value has surpassed the size of the economy of most modern nations.
  • Despite its increasing acceptance globally, India has followed its usual approach of ‘bar what you can’t understand, ban what you can’t control’.
  • In 2018, the Reserve Bank barred our financial institutions. It was from supporting crypto transactions, but the Supreme Court overturned it in 2020.
  • Further, the government has circulated a draft bill outlawing all cryptocurrency activities. It has been under discussion since 2019.
  • More recently, the Reserve Bank has announced the launch of a private blockchain-supported official digital currency, similar to China’s digital Yuan.
  • However, launching official digital currency is impractical, and shows a lack of understanding of this disruptive innovation.
Why India is hesitant to accept cryptocurrencies?

Though Cryptocurrencies have many advantages, there are few concerns associated with them,

  • One, extreme volatility. For example, China’s recent crackdown on cryptocurrency wiped out a trillion US dollars from the global crypto market within a span of 24 hours.
  • Two, it can be used as an instrument for illicit activities, including money laundering and terror funding as there are no regulations.
What is the significance of Blockchain technology?

The underlying technology of Cryptocurrencies is Blockchain technology. Blockchain network performs functions such as verification of transactions and contracts and the updating and maintenance of these records in the form of tamper-proof ledgers. It serves many purposes.

  • One, currently, intermediaries (including banks, credit card, and payment gateways) draw almost 3 percent from the total global economic output of over $100 trillion, as fees for their services. Integrating blockchain into these sectors could result in hundreds of billions of dollars in savings.
  • Two, Blockchain can make every aspect of e-governance, judicial and electoral processes more efficient and transparent.
  • Three, it can make our digital space more redistributive and fairer. For instance, Tech firms, including titans like Google and Facebook, derive most of their value from their multitude of users. Blockchain could enable these internet customers to receive micro-payments for any original data they share in the digital space including ratings, reviews, and images.

Despite its significance, regulatory uncertainty is hampering the growth of blockchain start-ups in India. For instance, blockchain start-ups worldwide received venture funding of $ 2.6 billion. Whereas, in India, less than 0.2 percent of the amount the sector raised globally have gone into the Indian blockchain start-ups

Way forward
  • India has been a late adopter in all the previous phases of the digital revolution. Like semiconductors, the internet, and smartphone technology (4G and 5G).
  • Currently, we are witnessing the next phase in a digital revolution led by technologies like blockchain.
  • Channelizing India’s human capital, expertise, and resources supported with the right policies will help India to make the most benefit of it.

IFFCO launches world’s first “Nano Liquid Urea”

Read More
What is the News?

Indian Farmers Fertiliser Cooperative Limited(IFFCO) has launched the world’s first Nano Urea Liquid

What is Nano Liquid Urea?
  • Nano Urea Liquid is a nutrient to provide nitrogen to plants as an alternative to conventional urea.
  • Developed by: Nano Urea Liquid has been developed indigenously through proprietary technology at IFFCO”s Nano Biotechnology Research Centre(NBRC) in Gujarat.
  • Efficacy Trials: IFFCO had conducted around 11,000 farmer field trials (FFT’s) on more than 94 crops across India to test the efficacy of nano urea. The trials had shown an average 8% increase in yield.
What are the benefits of Nano Liquid Urea?
  • Firstly, Nano Liquid Urea can curtail the requirement of urea by at least 50%. This will in turn reduce India’s dependence on urea imports.
    • During 2019-20, the production of urea was 244.55 LMT. On the other hand, the consumption volume of urea was 336 lakh metric tonnes. This leaves a gap of over 91 LMT. India imported 91.99 LMT urea fertiliser in 2019-20 to fill this gap.
  • Secondly, nano urea liquid is significant as its use by farmers will boost balanced nutrition programs by reducing the excess use of Urea application in the soil. This will help make the crops stronger, healthier and protect them from the lodging effect.
  • Thirdly, the conventional urea is 30-40% effective in delivering nitrogen to plants while the effectiveness of the Nano Urea Liquid is over 80%.
  • Fourthly, the Nano Urea Liquid will be cost-effective as it will be cheaper. This will help in increasing farmers’ income.
  • Lastly, Nano Urea Liquid will have a positive impact on the
    • Quality of underground water

  • This method ensures the precise and effective delivery of drugs to specific cells. Hence, this method could have an impact on treating diseases like pancreatic cancer.

What are biological drugs(biologics)?

  • A biologic drug (biologics) is a product that is produced from living organisms or contains components of living organisms. The composition may include sugars, proteins, or nucleic acids or complex combinations of these substances.
  • The biological drug works by targeting a defective protein in the system by delivering proteins to it.
    • For example in case of insulin treatment. If a person is short of insulin, (which is a protein), then s/he will get an insulin shot to balance the system.
How are Biologics different from conventional drugs?
  • Conventional Drugs are made from chemical processes to create the active ingredient compound in a traditional lab.
    • On the other hand, a biologics drug is defined as a drug derived from living cells. They are not chemically manufactured.
  • Conventional Drugs generally have well-defined chemical structures. On the other hand, biologics are complex mixtures that are not easily identified or characterized.
What are Antibody Drug Conjugates?
  • Antibody-drug conjugates or ADCs are a class of biopharmaceutical drugs designed as a targeted therapy for treating diseases like cancer.
  • Unlike chemotherapy, ADCs are intended to target and kill tumour cells while sparing healthy cells.

Note: Antibodies is a protective protein produced by the immune system in order to attack antigens. The antigen is a toxin or other foreign substances that induces an immune response in the body.

Significance of “Nanophotonics”

Read More

What is the News?

Researchers from the University of Hyderabad have developed a technique named “mechanophotonics”. It has allowed them to move, slice, bend, and lift micron-sized wave guiding crystals using atomic force microscopy.

Significance of Research: This ability to manipulate micron-sized crystals with precision and control is very useful in the field of nanophotonics. It focuses on building circuits, driven entirely by photons (light).

What is Nanophotonics or nano-optics?

  • It is the study of the behavior of light on the nanometer scale and the interaction of nanometer-scale objects with light. It is a branch of optics, optical engineering, electrical engineering, and nanotechnology.
    • Nanometer: It is equal to one billionth of a meter. One nanometre can be expressed in scientific notation as 1×10−9 m.

Applications of Nanophotonics:

Solar cells:

  • Solar Cells often work best when the light is absorbed very close to the surface. It is because electrons near the surface have a better chance of being collected. Moreover, the device can be made thinner, which reduces cost. Researchers have investigated a variety of nanophotonic techniques to intensify light in the optimal locations within a solar cell.

Optical Technology

  • Nano-Photonics can help achieve an unprecedented level of miniaturization. It is useful for all-optical-based technologies such as pliable, wearable devices. These are operated by light entirely.

Integrated Circuits(IC)

  • Nanophotonics would make it possible to go beyond current electronics. It will build up integrated-circuits driven entirely by photons(light).

Spectroscopy

  • If a given amount of light energy is squeezed into a smaller and smaller volume (“hot-spot”), the intensity in the hot-spot gets larger and larger. This is especially helpful in nonlinear optics, an example is surface-enhanced Raman scattering.

“CHIME telescope” detects numerous “Fast Radio Bursts”

Read More

What is the news?

Scientists from the Canadian Hydrogen Intensity Mapping Experiment (CHIME) have detected 535 Fast Radio Bursts (FRB). It is the largest collection of FRB till date.

CHIME telescope (Source: Wiki)

  • They have detected this in collaboration with India’s Tata Institute for Fundamental Research (TIFR) and the National Centre for Radio Astrophysics (NCRA).
Also read: India’s Thirty Meter telescope

 

What are Fast Radio Bursts (FRBs)?

  • FRBs are bright bursts of radio waves (radio waves can be produced by astronomical objects with changing magnetic fields) that blaze for a few milliseconds before vanishing without a trace.
  • They are spotted in various and distant parts of the universe as well as in our own galaxy. However, their origins are still unknown, and their appearance is highly unpredictable.
  • The first FRB was spotted in 2007. Since then, scientists had only caught sight of around 140 bursts in their telescopes.
  • Source: Magnetars could be the source of some fast radio bursts(FRBs).

What is a Magnetar?

  • Magnetar: It is a type of neutron star. The magnetic field of such a star is very powerful. It can be over a thousand times stronger than a typical neutron star’s magnetic field.
  • Neutron: The formation of a neutron star occurs when the core of a massive star undergoes gravitational collapse at the end of its life.
Fast Radio Bursts (FRBs) discovered by CHIME Telescope
  • The CHIME telescope has detected 535 new fast radio bursts in its first year of operation between 2018 and 2019.
  • Location of FRBs: When the scientists mapped their locations, they found the FRBs were evenly distributed in space, seeming to arise from any and all parts of the sky.
  • Types: The newly discovered FRBs appear to fall into two distinct classes: those that repeat and those that don’t repeat.
    • The repeater FRBs looked different. Each burst lasted slightly longer and emitted more focused radio frequencies than bursts from non-repeating FRBs.
    • These differences strongly suggest that emission from repeaters and non-repeaters is generated either by different physical mechanisms or in different astrophysical environments.
  • Significance: Scientists hope that the CHIME telescope will soon help them discover more properties of fast radio bursts and know more about the possible sources they are coming from.
CHIME Telescope
  • Canadian Hydrogen Intensity Mapping Experiment (CHIME) is a radio telescope designed to answer major questions in astrophysics and cosmology.
  • The telescope is a partnership between the University of British Columbia, McGill University, the University of Toronto and the Canadian National Research Council’s Dominion Radio Astrophysical Observatory.
  • Working of CHIME Telescope:
    • The CHIME telescope functions a bit differently from others used for radio astronomy. Most radio astronomy is done by rotating a large dish to focus light from different parts of the sky.
    • On the other hand, the CHIME telescope comprises four massive parabolic radio antennas. It has no moving parts, and it receives radio signals each day from half of the sky as the Earth rotates.
    • The telescope has a powerful digital signaling processor that works at about seven terabits per second – equivalent to a few percent of the world’s internet traffic.
    • This digital signal processor reconstructs and looks in thousands of directions simultaneously. That’s what helps it to detect FRBs a thousand times more often than a traditional telescope.
  • Location: The telescope is located at Dominion Radio Astrophysical Observatory in British Columbia, Canada.

What are “Overture supersonic aircraft” and what are its challenges?

Read More
What is the news?

Plans to buy 15 new Overture supersonic Aircraft have been announced by US-based United Airlines. These aircrafts are planned to be open for passengers by 2029.

What are Supersonic Flights?

  • Supersonic aircraft are planes that can fly faster than the speed of sound.
  • Usually, supersonic planes can travel at the speed of around 900 kmph, twice the speed of normal aircraft.

Read Also :-Centre eyes seaplanes in UDAN 3 

First Supersonic Aircraft:
  • Concorde, the British-French turbojet-powered commercial airliner, was the first aircraft to carry passengers at supersonic speed.
  • But eventually, the aircraft had to be discontinued due to cost and other concerns.
What about the Overture supersonic aircraft?
  • The Overture supersonic aircraft would travel at the speed of Mach 1.7 or 1,805 kmph. In a single flight, it could carry 65 to 88 passengers.
  • The aircraft will also not be noisy, as supersonic planes in the past were, as it aims for “zero overland noise.
    • Zero overland noise essentially means that the aircraft will fly at supersonic speeds only overwater. Thereby ensuring no sonic boom or excessive noise reaches the surfaces where people live.
Challenges with Supersonic Flights:
  • Environment Pollution: The costs of making sustainable supersonic planes are extremely high. This is because using excessive amounts of fuel and energy is likely to have high environmental costs.
  • Excessive Noise: Travelling faster than the speed of sound causes a sonic boom which can be heard on the ground as a loud thunderclap or explosion. This limits where and when the supersonic planes can fly.
  • High Cost: Supersonic aircraft would not be economically feasible for everyone. Only the very rich can afford supersonic planes, as a ticket is likely to be way more costlier than a first-class ticket of a regular plane.

ISRO develops 3 types of ventilators(PRENA, VaU, SVASTA) to battle Covid-19

Read More
What is the News?

Indian Space Research Organisation(ISRO) has developed three types of ventilators(PRENA, VaU, SVASTA). These three ventilators have been developed at Vikram Sarabhai Space Centre(VSSC), a major space research centre of ISRO in Kerala.

Moreover, ISRO has said that it will transfer the technology of these ventilators to industry for clinical usage as India battles the second wave of Covid-19 pandemic.

Which are those three ventilators developed by ISRO?

 PRANA(Programmable Respiratory Assistance for the Needy Aid):

  • PRANA is a low-cost and portable critical care ventilator. The ventilator is based on the automated compression of an AMBU (Artificial Manual Breathing Unit) bag.
    • AMBU is a device commonly used to provide positive pressure ventilation to patients who are not breathing or not breathing adequately.
    • Positive pressure ventilation is a form of respiratory therapy that involves the delivery of air or a mixture of oxygen combined with other gases by positive pressure into the lungs.
  • Features:
    • The ventilator has a control system that includes an airway pressure sensor, flow sensor, oxygen sensor as well as expiration and PEEP (Positive End Expiratory Pressure) control valve.
    • The ventilator supports both invasive and non-invasive ventilation modes.
    • It is capable of giving mandatory breaths (controlled by a ventilator) as well as spontaneous breaths (controlled by the patient).
    • A robust algorithm for controlled and safe ventilation of the patient is implemented in the device. This raises an alarm and opens safety valves to prevent barotrauma, asphyxia during the ventilation.
    • There are also provisions to attach bacterial viral filters at each interface to prevent cross-infection and the contamination of air.
VaU(Ventilation assist Unit):
  • VaU is an ICU grade positive pressure mechanical ventilator. It can assist or replace spontaneous breathing problems in patients under respiratory distress.
  • Working: The ventilator is based on a centrifugal blower that draws in filtered ambient air, compresses it and delivers it to the patient to achieve ventilation. It can therefore operate without a compressed pneumatic source.
  • The ventilator has been configured to operate in a variety of patient/ventilator triggered invasive and non-invasive ventilation modes. It also has provisions to detect fault conditions and raise alarms.
Space Ventilator Aided System for Trauma Assistance(SVASTA)
  • SVASTA is a gas-powered ventilator. It can be used for non-invasive ventilation. Hence, it is well-suited for emergency use for first-line treatment and as transit ventilators inside vehicles.
  • Working: The ventilator runs on compressed air. It is able to perform various ventilation conditions using manual mechanical settings.
  • Significance: The basic design of the ventilator is simple as the components of it can be easily mass-produced for emergency use in pandemic like situations.

“Anti-hail guns” and their application in preventing hail storm

Read More
What is the news?

‘Anti-hail guns’, developed indigenously, will be tested by the Himachal Pradesh government to help out horticulturists who face crop damage due to hailstorms.

What are anti-hail guns?
  • An anti-hail gun is a machine that generates shock waves to disrupt the growth of hailstones in clouds.
Who has developed these anti-hail guns?

These anti-hail guns have been developed indigenously by IIT Bombay along with Dr Y S Parmar University of Horticulture and Forestry at Nauni (Solan). They are likely to be much cheaper than the imported ones.

How do anti-hail guns prevent a hail storm?

  • Anti-hail gun comprises a tall, fixed structure somewhat resembling an inverted tower, several meters high with a long and narrow cone opening towards the sky.
  • The gun is “fired” by feeding an explosive mixture of acetylene gasair into its lower chamber. This releases a shock wave (waves that travel faster than the speed of sound, such as those produced by supersonic aircraft).
  • These shock waves supposedly stop water droplets in clouds from turning into hailstones, so that they fall simply as raindrops.
What are Hailstorms?
  • A hailstorm is an unusual weather phenomenon in which balls of ice, called hail, fall from the sky. The ice balls are nothing more than solid precipitation that forms under certain conditions.
How are Hails formed?
  • Hails are formed by cumulonimbus clouds which are generally large and dark and may cause thunder and lightning.
  • In such clouds, winds can blow up the water droplets to heights where they freeze into ice.
  • The frozen droplets begin to fall but are soon pushed back up by the winds and more droplets freeze onto them, resulting in multiple layers of ice on the hailstones.
  • This fall and rise are repeated several times, till the hailstones become too heavy and fall down.
Previous such anti-hail guns used in Himachal:
  • In 2010, the Himachal Pradesh government had imported three anti-hail guns from the United States. They were installed in the apple-growing belt of Shimla where hailstorms in summer cause severe damage to the fruit every year.
  • Two of the machines are currently functional, while the third one was rejected by local residents.
  • State horticulture department officials maintain that since the installation of the guns, hail has occurred very few times in the villages.

What is the News?

The Union government is in talks with foreign manufacturers of COVID-19 vaccines on their demand for Indemnity from liability as a condition for selling their vaccines to the country.

However, this has already given rise to a similar demand from domestic vaccine-maker Serum Institute of India(SII). As they believe, all players should be treated the same way.

What is Indemnity?
  • In simple terms, indemnity means security against a loss or other financial stress. This is commonly used in insurance contracts.
  • In legal terms, It protects the manufacturers from any potential civil-legal liability or immunity from being sued by people for any unforeseen complications arising from their COVID-19 vaccine.
Is Indemnity defined under the law on Drugs?
  • The law on drugs in India does not have a provision for indemnity related to the grant of approval for any new drug or vaccine in the country.
Where is Indemnity defined then?
  • Section 124 of the Indian Contract Act, 1872 defines a contract of indemnity. It is defined as a contract by which one party promises to save the other from any loss caused to the latter.
  • If the government gives an indemnity to vaccine manufacturers, then the government, and not the vaccine maker, would be liable to compensate any citizen who claims to have side effects/death due to taking the vaccine.
  • In the event of a court ordering payment, the company will be in a position to recover the amount from the government.

Is the demand for indemnity a standard practice?
  • Indemnity is essentially a contractual matter between the supplier and recipient.
  • For example, Pfizer is believed to have obtained indemnity from several countries including the United Kingdom. However, it has declined to discuss the issue in public.
What have the overseas vaccines companies got so far?
  • Firstly, the Drugs Controller-General of India has fast-tracked the import of vaccines by dispensing with the need for local trials.
  • Secondly, foreign-produced vaccines that had been granted emergency approval for restricted use by certain regulators will also be granted Emergency Use Authorisation in India. These regulators include regulators in the US, UK, European Union and Japan or vaccines included in the WHO’s Emergency Use Listing.
  • Thirdly, the New Drugs and Clinical Trial Rules, 2019 has set down stringent regulations for grant of approval as well as for trials.
    • The Rules provide for payment of compensation by the sponsor of the trial or its representative to any participant who dies or suffers disability as a result of such trials.
    • However, exemption from these trials has reduced the risk to overseas manufacturers.

Voluntary Licensing Mechanism for Vaccines Will Ensure Social Justice

Read More

Synopsis: Other alternatives available to boost Vaccine supply are less effective. But Voluntary licensing Mechanism for Covid 19 vaccines will lead to affordable and accessible vaccines.

 Background
  • Affordable vaccination is the key to achieve global herd immunity and to prevent new strains of COVID-19.
  • To make vaccines affordable there are multiple arrangements globally. Such as
    • Voluntarily licensing: Manufacturers can place their licensing agreements for which they owned patent rights in the UN-affiliated Medicines Patent Pool.
    • Compulsory licensing: Through TRIPS Waiver on Patent rights, for Covid-19 vaccines under WTO TRIPS agreement.
    • COVAX Program: It was established to purchase vaccine doses and donate them to low-income countries but does not involve modifying patent rights
    • WHO’s COVID-19 Technology Access Pool: a patent-sharing pool for Covid-19 products.
  • However, a voluntary licensing mechanism will be more effective in achieving the target of affordable and universal vaccination. Further, it has been successfully demonstrated in making AIDS drugs more affordable.
How voluntary licensing can make medical drugs affordable?
  • The case study of AIDS drugs can better explain how voluntary licensing can make medical drugs/ vaccines more affordable.
  • During the 1990s, the WTO started implementing a global intellectual property regime known as the Trade-Related Aspects of Intellectual Property Rights agreement (TRIPS).
  • After that, there was anti-TRIPS activism around the globe due to fear of price rise of essential medicines because of the TRIPS agreement.
  • Responding to anti-TRIPS activism from low-income countries, some manufacturers who owned patent rights to produce AIDS drugs placed their licensing agreements in the UN-affiliated Medicines Patent Pool.
  • This allowed Several India-based companies to use the voluntary licences to manufacture these drugs on a massive scale and sell them at prices they determine.
  • This effort brought down the price of key AIDS medications in low-income countries. For instance, tenofovir, the first-line treatment for HIV/AIDS, has come down in price from $200-$500 per person per year to $39 per person per year in low-income countries.
What are the issues in other alternative mechanisms?
  1. First, the Voluntary licensing mechanism will reduce the cost and time taken to manufacture vaccines compared to producing vaccines through a ‘Compulsory licensing agreement’.
    • Voluntary licensing enables goodwill among Patent right holding companies and general manufacturers.
    • It will enable easy flow of “technology transfer” thereby reducing the cost and time taken to manufacture vaccines.
      • About Compulsory licensing:
      • Compulsory licenses is a mechanism to override patent rights. It allows local production or import of drugs by generic manufacturers in the event of a public health crisis.
      • This right has been enshrined in the Doha Declaration addendum to the WTO’s TRIPS agreement.
      • This is what India and South Africa are lobbying for in the WTO, having recently been joined by the United States.
  2. Second, COVAX Programme faces the issue of underfunding. Also, Similar attempts like COVAX Programme during the AIDS crisis were chronically underfunded and had only minor effects on that pandemic compared to the voluntary licensing.
  3. Third, the WHO’s COVID-19 Technology Access Pool too faces issues similar to COVAX Programme. For instance, no patent holders have joined this effort. This is the reason why India and South Africa called on the WTO to temporarily waive patent protections for COVID-19.
Way forward
  • Patents are not absolute ownership rights. They are a temporary contract that balances the public interest with the claims of the innovator.
  • Further, billions of dollars are spent through public money to develop COVID-19 vaccines.
  • Considering the above facts, patent owners should enable the mass production of affordable vaccines by granting voluntary licensing for Covid-19 vaccines.

What is Compulsory Licensing?

Read More
What is the News?

Kerala High Court has asked the Centre to respond to a plea for invoking the compulsory licensing. Other capable vaccine manufacturers will also be able to produce Covid-19 vaccines by the use of the compulsory license.

About Compulsory Licensing:
  • Compulsory licensing(CL) is a process that allows governments to license third parties (that is, parties other than the patent holders) to produce, use and sell a patented product or process. By that, producers can manufacture patented drugs without the requirement of consent of patent owners.
  • The WTO’s agreement on intellectual property –TRIPS allows countries to issue compulsory licenses to domestic producers.
  • In India, Compulsory licensing is allowed and regulated under the Indian Patent Act, 1970.

Section 84 of the (Indian) Patent Act,1970: It provides that after three years from the date of the grant of a patent, any person can apply for the compulsory license, on certain grounds:

  • the reasonable requirements of the public with respect to the patented invention have not been satisfied
  • the patented invention is not available to the public at a reasonably affordable price
  • Lastly, the patented invention is not used in the territory of India.

However, compulsory licenses can also be granted under exceptional circumstances.

Section 92 of the (Indian) Patent Act,1970: It authorizes the central government to issue a compulsory license at any time after the grant of the patent, in the case of:

  • National emergency; or
  • Extreme urgency; or
  • Case of public non-commercial use.

After the government issues a notification under Section 92 the companies can approach the government for a license. They can start manufacturing the patented drug by reverse-engineering the product.

Section 100 of the (Indian) Patent Act,1970:
  • It gives the central government the power to authorize anyone to use the invention for the purposes of the government.
  • Basically, this provision enables the government to license patents of the vaccine to specific companies. This is done to speed up manufacturing and ensure equitable pricing.

What is a Patent?

  • Firstly, a patent is an exclusive right granted for an invention. In other words, a patent is an exclusive right to a product or a process that generally provides a new way of doing something or offers a new technical solution to a problem.
  • Secondly, is a patent valid in every country? Patents are territorial rights. In general, the exclusive rights are only applicable in the country or region in which a patent has been filed and granted in accordance with the law of that country or region.
  • Thirdly, how long does a patent last? The protection is granted for a limited period, generally 20 years from the filing date of the application.

Issues Associated with IPR Waiver to Covid Vaccine

Read More

Synopsis: IPR waiver will not bring instant benefits. Thus, efforts must be made to share the excess stockpiles of vaccines lying with the developed countries.

Introduction 

The Biden administration announced that it would support a waiver on intellectual property rights (IPR) for the production of COVID-19 vaccines. 

  • The original plan, for TRIPS waiver for Covid vaccines, was drafted at the WTO by India and South Africa last year.
  • During the 2020 U.S. presidential election, Joe Biden made a promise to share vaccine technology with countries that needed it if he won. He was expecting the deep gap of inequality in vaccine access.
How has the world reacted to this stance?

This policy stance of US has been rejected by major EU nations and met with counter-suggestion.

  • The first refusal came from Germany. They said that it would create major complications for the production of vaccines, the major pharma corporations resonated with this view. 
  • French President Emmanuel Macron was relatively less antagonistic to considering the proposal. However, he lashed out at the Anglo-Saxons for hindering vaccine availability globally by blocking the export of ingredients.
  • There is some substance to the argument that an IPR waiver may not fully resolve the vaccine shortage issue in countries suffering the worst of the pandemic now, even if it were to become a reality.
What to do?
  • Firstly, the grant of a waiver would have to be supplemented by technology transfer. It will provide the pharmaceutical manufacturers with the required trained personnel, raw materials, and high-tech equipment and production know-how.
  • Secondly, after tech transfer, there must be a scientific criterion to test the safety, immunogenicity, and protective efficacy of the vaccine developed by these generic manufacturers.  
  • Thirdly, the effect on global supply chains for vaccine production should be inspected so major troubles might be avoided. 
  • Lastly, other options to instantly address vaccine shortages should be considered. Developed nations should share a considerably greater part of their vaccine stockpiles, particularly in cases where the latter exceed projected domestic needs.

Conclusion 

  • There is a rumor that Mr. Biden’s waiver announcement might be a tactic to persuade pharmaceutical companies to accept less painful measures. This includes
    • sharing some of their technology willingly,
    • agreeing to joint ventures to increase global production expeditiously, and
    • simply producing more doses at affordable prices to donate directly to where the need is most severe, especially in India.

How to Read Science and Technology for UPSC IAS

UPSC IAS syllabus for Prelims and Mains, both include Science and technology subject. It is the subject where most of the students feel that it is not a level playing field for all. Mainly students from the non-Science background have this mentality. But this is not the reality. UPSC in all its syllabus starting from Prelims to Mains, has put focus on providing level playing field, as lakhs of students from different academic backgrounds prepare for this exam.

No matter whether you belong to Arts, Commerce or Science background, this subject is easy to understand and score well in exam (including Prelims and Mains). This subject demands simple basic understanding of science. It includes day to day happenings related to science and technology and general science. Questions are mostly application based. One does not have to master the subject. Aspirants only need to pay little attention to what all are happening around them by keeping their ear and eyes open all the time.

In this article, we will discuss about the study approach of science and technology for UPSC IAS. Before starting the preparation, it is important for all the students to see the past year trend of science and technology questions and syllabus for the same.

In the following table, we will see the total number of questions asked from science and technology in last 5 years:

YearTotal number of questions asked
202011
201911
201813
20176
201610

Overview of the UPSC IAS Syllabus for science and technology:

ExamSyllabus
UPSC Prelims- General Studies (Paper I)General Science
UPSC Mains-General Studies (Paper III)Science and Technology- developments and their applications and effects in everyday life.

Achievements of Indians in science & technology; indigenization of technology and developing new technology.

Awareness in the fields of IT, Space, Computers, robotics, nano-technology, biotechnology and issues relating to intellectual property rights.

Study approach for science and technology for UPSC: As questions asked from science and technology are mostly application based and basic in nature, it becomes easy for the students to read this subject and score well in the exam. It is only possible when they will understand the subject rather than only mugging it up.

  • Start with NCERT textbooks:Students should compulsorily start with class VI NCERT textbook. They should read the whole book first and then in their second reading they should make short notes of them. Reading the whole book again will not be feasible. Likewise, they should complete all the NCERTs from Class VI to Class X. Notes making is very important here. Students should see if anything getting repeated.
  • Read one newspaper daily:Newspaper reading is must for an IAS aspirant. It becomes very much important for subjects like science and technology. Students must focus on science-based articles and columns.
  • Refer one current affairs magazine: To complete the current events of science and technology, it is very important to read and revise one good magazine which covers the topics thoroughly.
  • Refer Government official website:To cover schemes related to science and technology, students must refer website of Ministry of Science and Technology. They can also refer PIB website.
  • Solve Previous year UPSC Prelims and Mains questions: Past year papers will help students to understand which type of questions are asked from this subject. They will also get to know exactly what are application-based questions on science and technology. It will help them in newspaper reading and notes making as well. So, students must see the questions many times, analyze them and understand the type of the questions. In this stage they should not hurry.
  • Solve as many MCQs as possible:Solving questions of science and technology will increase their confidence as well as increase their marks. It will build their logic on how to solve application-based questions. It would be very helpful for those who belong to non-science stream.
  • Daily answer writing practice: Most of the students find it difficult to write answers on science and technology. It becomes really tough when topics are biotechnology and nanotechnology. Here is the utility of daily answer writing. If students will write answers daily, gradually they will improve. And if they will practice the same for months, then this will definitely improve their content quality as well as quality. Their speed will increase with this practice.
  • Revision is important: Students keep on revising their notes and current affairs magazines. As initially they will find the subject difficult, but with revision, they can perform well in the exam.

Science and technology is very interesting subject where most of the questions asked are of application based. So. If students will once understand the topic, they can perform well in less time period. So, no matter you belong to which background, if you want to get the success, start preparing this subject seriously with right study approach. Make a timetable and start the study. All the best for your exam.
