What are Gravitational Waves?
- Gravitational waves were first postulated (1916) in Albert Einstein's General Theory of Relativity, which explains how gravity works.
- These waves are produced by the movement of massive celestial bodies, such as black holes or neutron stars, and are the ripples in spacetime that propagate outward.
What is LIGO?
- About: LIGO is an international network of laboratories that detect gravitational waves.
- LIGOs are designed to measure changes in distance that are several orders of magnitude smaller than the length of the proton. Such high precision Instruments are needed because of the extremely low strength of gravitational waves that make their detection very difficult.
- First Detection of Gravitational Waves:
- The LIGO in the US first detected gravitational waves in 2015, which led to a Nobel Prize in Physics in 2017.
- These gravitational waves were produced by the merger of two black holes, which were about 29 and 36 times the mass of the Sun, 1.3 billion years ago.
- Black hole mergers are the source of some of the strongest gravitational waves.
- The LIGO in the US first detected gravitational waves in 2015, which led to a Nobel Prize in Physics in 2017.
- Operational LIGO:
- Besides the United States (in Hanford and Livingston), such gravitational wave observatories are currently operational in Italy (Virgo) and Japan (Kagra).
- To detect gravitational waves, four comparable detectors need to be operating simultaneously around the globe.
- Besides the United States (in Hanford and Livingston), such gravitational wave observatories are currently operational in Italy (Virgo) and Japan (Kagra).
- Working Mechanism:
- LIGO consists of two 4-km-long vacuum chambers, set up at right angles to each other, with mirrors at the end.
- When light rays are released simultaneously in both chambers, they should return at the same time.
- However, if a gravitational wave arrives, one chamber gets elongated while the other gets squished, causing a phase difference in the returning light rays.
- Detecting this phase difference confirms the presence of a gravitational wave.
UPSC Civil Services Examination, Previous Year Question (PYQ)
Q. Recently, scientists observed the merger of giant ‘blackholes’ billions of light-years away from the Earth. What is the significance of this observation? (2019)
(a) ‘Higgs boson particles’ were detected.
(b) ‘Gravitational waves’ were detected.
(c) Possibility of intergalactic space travel through ‘wormhole’ was confirmed.
(d) It enabled the scientists to understand ‘singularity’
Ans: (b)
Exp:
- Every few minutes a pair of black holes smash into each other. These cataclysms release ripples in the fabric of space time known as gravitational waves.
- Gravitational waves are ‘ripples’ in space-time caused by some of the most violent and energetic processes in the Universe.
- Albert Einstein predicted the existence of gravitational waves in 1916 in his General Theory of Relativity.
- The strongest gravitational waves are produced by catastrophic events such as colliding black holes, the collapse of supernovae, coalescing neutron stars or white dwarf stars, etc.
- Scientists have yet again detected gravitational waves produced by the merger of two light black holes about a billion light-years away from the Earth.
- It was recorded by Laser Interferometer Gravitational-Wave Observatory (LIGO).
- Therefore, option (b) is the correct answer.
Medical Device and Malware
For Prelims: Medical Device and Malware, Ransomware, Cyberattacks, Trojan Horses, Cyber Surakshit Bharat, Cyber Swachhta Kendra.
For Mains: Implications of malware attacks on medical devices and the measures.
Why in the News?
Recently, some experts have warned that Common medical devices such as oximeters, hearing aids, glucometers, and pacemakers can be turned into Ransomware.
- Industry experts are now seeking urgent Central government intervention to recognize this threat and immediately put in place measures to plug any possible drain.
- The warning comes close on the heels of the ransomware attacks suffered by India’s top tertiary care hospitals, leading to the siege of millions of medical records and vast amounts of health data at Delhi’s AIIMS, Safdarjung Hospital etc.
What are the Concerns?
- Data Breaches:
- The increasing use of medical technology devices and the lack of adequate cyber protection for these devices have raised concerns about data breaches and cyberattacks in the healthcare industry.
- Such devices contain software as medical devices (SaMD) and software in medical devices (SiMD), and are typically connected to the internet, mobile phones, servers, and the cloud and thus vulnerable to attacks.
- Sun Pharma, the fourth-largest generic pharmaceutical company in the world and an Indian multinational corporation, was targeted in the recent cyberattacks along with the Indian Council of Medical Research (ICMR).
- Vulnerable Population:
- India is among the world’s top 20 markets for medical devices, with the medical devices sector projected to reach USD 50 billion by 2025. However, the rapid economic growth, rising middle-class incomes, and increased market penetration of medical devices have left the population vulnerable to cyber threats.
- Inadequate Systems:
- Furthermore, the Indian healthcare industry lacks a centralized data collection mechanism, which makes it challenging to determine the exact cost of data corruption.
- Despite this, it is evident that data has become the new oil and is seeing a significant threat from cyberattacks.
How can we Address Such Cyber Threats?
- Consultation with the Experts: The government should consult with industry experts to identify the challenges that could pose a risk to national security.
- Employee Training: Employees should be trained in how to recognize and avoid phishing emails, which are commonly used to initiate ransomware attacks.
- Data protection is not a rocketing science, but requires legal and technical artisanship, the allocation of adequate resources and the training of all professionals involved in the processing of personal data.
- Regular Software Updates: Regular software updates can help address vulnerabilities that hackers might exploit.
- Access Control: Limiting access to medical devices to only authorized personnel can prevent unauthorized individuals from accessing the devices and infecting them with malware.
- Encryption: Encryption can be used to protect the data on medical devices from unauthorized access.
- Network Segmentation: Segmenting the network can help prevent the spread of malware from one device to another.
What are the Major Types of Cyber Threats?
- Ransomware: This type of malware hijacks computer data and then demands payment (usually in bitcoins) in order to restore it.
- Trojan Horses: A Trojan horse attack uses a malicious program that is hidden inside a seemingly legitimate one.
- When the user executes the presumably innocent program, the malware inside the Trojan can be used to open a backdoor into the system through which hackers can penetrate the computer or network.
- Clickjacking: Act of tempting internet users to click links containing malicious software or unknowingly share private information on social media sites.
- Denial of Service (DOS) Attack: The deliberate act of overloading a particular service like website from multiple computers and routes with the aim of disrupting that service.
- Man in Middle Attack: In this kind of attack, the messages between two parties are intercepted during transit.
- Crypto Jacking: The term Crypto jacking is closely related to cryptocurrency. Crypto jacking takes place when attackers access someone else’s computer for mining cryptocurrency.
- Zero Day Vulnerability: A zero-day vulnerability is a flaw in the machine/network’s operating system or application software which has not been fixed by the developer and can be exploited by a hacker who is aware of it.
- Bluebugging: It is a form of Bluetooth hacking in which an attacker exploits a vulnerability in a Bluetooth-enabled device to gain unauthorized access to it. The attacker can then use the compromised device to make calls, send messages, or access other data without the user's knowledge or consent.

Public Interest Immunity Claims Proceeding
For Prelims: Sealed Cover Proceedings, Public Interest Immunity Claims Proceedings.
For Mains: SC’s Observations over Sealed Cover Proceedings
Why in News?
Recently, the Supreme Court of India ruled on the use of sealed cover proceedings in courts and the telecast ban of a Malayalam channel.
- The Court criticised the government for silencing voices in the media and reducing constitutional rights and procedural guarantees of a fair hearing.
- The Court also devised an alternative procedure for Public Interest Immunity claims proceedings to replace the use of sealed covers.
What are Sealed Cover Proceedings?
- The sealed cover proceedings are often used in cases involving sensitive or confidential information, such as national security matters, or cases where the disclosure of the evidence may compromise the privacy of individuals involved.
- In such cases, the documents or evidence are submitted to the court in a sealed cover, and only the judge and a designated court officer are allowed to examine the contents of the sealed envelope.
- The parties to the case may not have access to the contents of the sealed cover, and the court may only rely on the information contained in the sealed cover to make its decision.
- Sealed cover proceedings are a means of balancing the need for transparency in the judicial process with the need to protect sensitive information or individuals' privacy.
- However, the use of sealed covers has reduced constitutional rights and procedural guarantees of a fair hearing under the law.
What is Public Interest Immunity Claims Proceeding?
- About:
- The Supreme Court evolved the “less restrictive” Public Interest Immunity (PII) claims proceedings as an “alternative” to the sealed cover proceedings while dealing with state requests for confidentiality.
- The PII proceedings would be a “closed sitting,” but a reasoned order allowing or dismissing the PII claim of the state should be pronounced in open court.
- Procedure – Role of Amicus Curiae:
- The court will appoint an amicus curiae, which means "friend of the court", to act as a bridge between the parties involved in public interest immunity claims.
- The court-appointed amicus will be given access to the materials sought to be withheld by the state and allowed to interact with the applicant and their lawyer before the proceedings to ascertain their case.
- The amicus curiae will not interact with the applicant or their counsel after the public interest immunity proceeding has begun and the counsel has viewed the document sought to be withheld.
- The amicus “shall to the best of their ability represent the interests of the applicant” and would be bound by oath to not disclose or discuss the material with any other person.
- The court will appoint an amicus curiae, which means "friend of the court", to act as a bridge between the parties involved in public interest immunity claims.
- Drawback:
- Since, Article 145 of the Constitution specifically mandates that all judgments of the Supreme Court be delivered in open court, closed sitting proceedings as per PII might fall against this constitutional mandate.
- SC’s Response: While the court recognised that public interest immunity proceedings will take place in a closed setting, it stated clearly that the court is required to pass a reasoned order for allowing or dismissing the claim in open court.
- Additionally, while PII claims also impact the principles of natural justice, sealed cover proceedings go a step ahead and infringe on the principles of natural justice as well as the principles of open justice.
- Since, Article 145 of the Constitution specifically mandates that all judgments of the Supreme Court be delivered in open court, closed sitting proceedings as per PII might fall against this constitutional mandate.
What are SC’s Previous Observations over Sealed Cover Proceedings?
- P. Gopalakrishnan vs The State of Kerala case (2019):
- The SC held that disclosure of documents to the accused is constitutionally mandated, even if the investigation is ongoing and documents may lead to a breakthrough in the investigation.
- INX Media case (2019):
- The Supreme Court had criticised the Delhi High Court for basing its decision to deny bail to a former Union Minister on documents submitted by the Enforcement Directorate (ED) in a sealed cover.
- It held the action as against the concept of fair trial.
- The Supreme Court had criticised the Delhi High Court for basing its decision to deny bail to a former Union Minister on documents submitted by the Enforcement Directorate (ED) in a sealed cover.
- Cdr Amit Kumar Sharma v Union of India case (2022):
- The SC said, “the non-disclosure of relevant material to the affected party and its disclosure in a sealed cover to the adjudicating authority…sets a dangerous precedent.

The Language Friendship Bridge
For Prelims: The Language Friendship Bridge, ICCR, Maulana Abul Kalam Azad, shared cultural heritage.
For Mains: Challenges and opportunities in implementing The Language Friendship Bridge Project.
Why in News?
The Indian Council for Cultural Relations (ICCR) has envisaged a project called ‘The Language Friendship Bridge’, which aims to expand cultural footprint in neighborhoods with whom India has historical ties.
- The project aims to enable India to translate its epics and classics, as well as contemporary literature, into these languages so that people in both countries can read them.
What is the Project about?
- About:
- The Project will create a pool of experts in languages spoken in countries like Myanmar, Sri Lanka, Uzbekistan and Indonesia to facilitate better people-to-people exchanges.
- It will train five to 10 people in the official languages of each of these countries.
- As of now, the ICCR has zeroed in on 10 languages: Kazakh, Uzbek, Bhutanese, Ghoti (spoken in Tibet), Burmese, Khmer (spoken in Cambodia), Thai, Sinhalese and Bahasa (spoken in both Indonesia and Malaysia).
- Though a number of universities and institutes offer courses in these languages, only a handful teach any of the 10 languages on the ICCR list.
- Sinhala, for example, is taught at the Banaras Hindu University and the School of Foreign Languages (SFL) under the Ministry of Defence.
- Significance:
- The project is significant for India's foreign policy and cultural diplomacy, as it will help deepen India's cultural and economic relations with these countries.
- By training language experts in the official languages of these countries, India will be able to communicate more effectively and build stronger cultural and economic ties with its neighbors.
- It is also particularly important in the current geopolitical context, as India is looking to strengthen its relations with its neighboring countries to counter China's growing influence in the region.
- By promoting cultural exchanges, India can build stronger people-to-people relations with these countries, which can help to counter the negative impact of Chinese economic and strategic initiatives in the region.
What is ICCR?
- The ICCR is an autonomous organisation of the Government of India under the Ministry of External Affairs.
- It promotes cultural diplomacy through cultural exchange with other countries.
- It was founded in 1950 by India's first Education Minister, Maulana Abul Kalam Azad.
- ICCR has been assigned the responsibility of facilitating the celebration of the International Day of Yoga by Indian Missions/Posts abroad since 2015.
- ICCR has instituted several awards, including the Distinguished Indologist Award, World Sanskrit Award, Distinguished Alumni Award, and Gisela Bonn Award, which are conferred upon foreign nationals for their contributions in different fields.
What are the Challenges?
- One of the major challenges is the lack of infrastructure and trained teachers in India to teach these languages. The project will require significant investment in setting up language centers and training teachers to teach these languages effectively.
- Additionally, the project will require significant resources to provide scholarships to Indian students to study these languages in the countries where they are spoken.
- Moreover, the project also faces the challenge of expanding the current list of languages, as there are several neighboring countries where India has significant cultural and economic ties, and whose languages are not currently included in the project.
Way Forward
- While the project faces several challenges, it also presents an opportunity for India to deepen its cultural and economic ties with its neighbors and counter China's growing influence in the region.
- Experts believe that the ICCR's list of languages needs to be expanded, as India sees a boom in cultural and economic ties with other neighboring countries as well.
- For example, with the rise of medical tourism, there is a need for a pool of translators and interpreters to facilitate the visits of people from countries like Turkey, Bangladesh, Afghanistan, and Maldives.
- JNU (Jawaharlal Nehru University) will soon be starting a course in Pashto to address this need.
Tiger Census 2022
Why in News?
The Prime Minister of India has released the figures of the 5th cycle of India’s Tiger Census 2022, revealing 6.7% in the increase in the past four years.
- The tiger census covered forested habitats in 20 states of India. Camera traps were set up at 32,588 locations and generated 47,081,881 photographs.
- The PM has released the Census while inaugurating the International Big Cat Alliance (IBC) in Karnataka’s Mysuru, organised to mark 50 years of Project Tiger.
What is the IBCA?
- IBCA is launched for conservation of seven big cats namely Tiger, Lion, Leopard, Snow Leopard, Leopard, Cheetah, Jaguar and Puma harbouring our planet.
- Its members include 97 countries that are home to these big cats and other interested parties.
- The IBCA will engage in advocacy, partnerships, capacity building, eco-tourism, and finance tapping.
- It will also disseminate information and create awareness among its members.
What are the Highlights of the Census?
- Population:
- Population has grown by 200 from 2018 to 2022. The current tiger population in India is 3,167, up from 2,967 in 2018.
- Growth Rate:
- The growth rate slowed to 6.7% in the four years from 2018 to 2022, from around 33% during 2014-2018.
- Increase:
- There has been a significant increase in the tiger population in the Shivalik Hills and Gangetic Plains, while tiger occupancy in Jharkhand, Odisha, Chhattisgarh, and Telangana showed a decline.
- The North East Hills and Brahmaputra Plains had 194 tigers captured by camera traps, and the region's Nilgiri cluster is the largest tiger population in the world, contributing significantly to colonisation of tigers in neighbouring areas.
- Decline:
- Tiger occupancy in the Western Ghats declined, the latest analysis showed. Significant declines were observed in the Wayanad landscape and in the Biligiriranga Hills.
- High Conservation Priority:
- The genetically unique and small population of tigers in Simlipal is also highlighted as being of high conservation priority.
- The report calls for ecologically viable economic development and trans-boundary tiger conservation strategies to sustain isolated populations.
What is the Need for Conserving Tigers?
- Biodiversity: Tigers are an apex predator and play a vital role in maintaining the ecological balance of their habitats. They help regulate prey populations, which in turn helps maintain the balance of other species in the ecosystem.
- Tourism: Tigers are a major tourist attraction in countries like India and help generate revenue through ecotourism. This revenue can support local communities and contribute to the economy.
- Cultural Significance: Tigers are an important cultural symbol in many cultures and religions, including Hinduism and Buddhism.
- Scientific Research: Tigers are an important subject of scientific research, as they are a keystone species, and their conservation can help protect other species in their ecosystem.
- Climate Change: Tigers are an indicator species, which means that their presence or absence can indicate the health of the ecosystem. Conserving tigers can help protect the ecosystem from the effects of climate change.
Tiger Census in India
- The national tiger census is done every four years by the National Tiger Conservation Authority (NTCA) in partnership with state forest departments, conservation NGOs, and the Wildlife Institute of India (WII). The census uses a double sampling method based on ground-based surveys and images from camera-traps.

Discovery of a New Uranium Isotope
Why in News?
In pursuit of a ‘magic number’, Physicists in Japan have recently discovered a new isotope of uranium with atomic number 92 and mass number 241.
What are the Major Highlights of the Discovery?
- About:
- The researchers accelerated uranium-238 nuclei into plutonium-198 nuclei at the KEK Isotope Separation System (KISS). In a process called multinucleon transfer, the two isotopes exchanged protons and neutrons.
- The resulting nuclear fragments contained different isotopes.
- The team used time-of-flight mass spectrometry to measure the mass of each nucleus.
- Findings:
- It was identified as uranium-241 and measured the mass of its nucleus. Theoretical calculations suggest that this new isotope could have a half-life of 40 minutes.
- This discovery is the first of its kind since 1979 due to the extreme difficulty of synthesising a nuclide in this region by general reaction.
- It was identified as uranium-241 and measured the mass of its nucleus. Theoretical calculations suggest that this new isotope could have a half-life of 40 minutes.
- Importance:
- This finding is significant in refining our understanding of nuclear physics and has implications in designing nuclear power plants and models of exploding stars.
- Measuring the mass of uranium and its neighbourhood elements yields essential nuclear information to understand the synthesis of such heavy elements in explosive astronomical events.

UPSC Civil Services Examination, Previous Year Question (PYQ)
Q. Consider the following statements: (2010)
- Biodiversity hotspots are located only in tropical regions.
- India has four biodiversity hotspots i.e., Eastern Himalayas, Western Himalayas, Western Ghats and Andaman and Nicobar Islands.
Which of the statements given above is/are correct?
(a) 1 only
(b) 2 only
(c) Both 1 and 2
(d) Neither 1 nor 2
Ans: (d)
Exp:
- The British biologist Norman Myers coined the term “biodiversity hotspot“ in 1988 as a biogeographic region characterized both by exceptional levels of plant endemism and by serious levels of habitat loss. To qualify as a hotspot, a region must meet two strict criteria – it must contain at least 1,500 species of vascular plants (which is more than 0.5% of the world’s total) as endemics, and it has to have lost at least 70% of its original habitat.
- There are currently 36 recognized biodiversity hotspots. While most of them are in tropical regions, some like Eastern Australian temperate forests, Succulent Karoo (South Africa), etc., are outside tropical regions. Hence, statement 1 is not correct.
- India hosts 4 biodiversity hotspots – the Himalayas, the Western Ghats, the Indo-Burma region and the Sundaland (includes Nicobar group of Islands). Hence, statement 2 is not correct.
- Therefore, option (d) is the correct answer
James Webb Space Telescope Captures Uranus and its Rings
Why in News?
The James Webb Space Telescope, launched in 2021, has captured a clear image of the planet Uranus and its rings.
What are the Major Points Related to Uranus?
- Uranus is an ice giant due to the chemical makeup of its interior, with most of its mass being a hot and dense fluid of icy materials like water, methane, and ammonia.
- Uranus rotates on its side, with a roughly 90-degree angle from the plane of its orbit. This leads to extreme seasons and long periods of sunlight and darkness.
- Uranus is among only two planets in our solar system that rotate clockwise along with Venus.
- The planet takes 84 earth years to orbit the Sun.
- Uranus has 13 rings, with 11 visible in the image. Some of the rings are very bright and close together, appearing as a larger ring.
- The planet also has 27 known moons.
- Uranus has a unique polar cap that appears during summer and vanishes in the fall. Webb's data can help scientists understand this mechanism.
- In 1986, NASA's Voyager 2 made the first - and so far, the only - visit to Uranus.
- New Horizons passes the orbit of Uranus on its way to Pluto, becoming the first spacecraft to journey beyond Uranus' orbit since Voyager 2.
What is a James Webb Space Telescope?
- The James Webb Space Telescope (JWST) is a large, infrared telescope designed to observe the most distant objects in the universe.

3D Printing
Bengaluru’s Ulsoor Bazaar post office is set to become home to India's first post office built using 3D printing technology. Three-dimensional printing, also known as additive manufacturing, is a revolutionary technology that is being increasingly used in the construction industry. With 3D printing, it is possible to create complex, customized, and intricate designs using computer-aided design (CAD) software.
This technology can be used to create parts, structures, and even entire buildings. One of the main advantages of 3D printing in construction is the ability to reduce construction time and costs. By eliminating the need for extensive formwork (Mold used to form concrete into structural shapes), scaffolding, and labor, the construction process can be streamlined, and significant savings can be achieved. Moreover, 3D printing allows for the creation of lighter and more durable structures that are also more environmentally friendly. Despite its many advantages, there are still some challenges associated with 3D printing in construction. One of the main challenges is the limited size of the printers, which makes it difficult to construct larger buildings. Additionally, the materials used for 3D printing are still limited, which limits the variety of structures that can be created.

Tamil Nadu Assembly Urges Time Frame for Approval of Bills
The Tamil Nadu assembly has passed a resolution urging the central government and President to establish a timeframe for governors to give their assent to bills adopted by the House. The resolution was passed following Governor remarks that bills that are withheld should be considered "dead”.
According to the Constitution, the governor cannot reject a bill sent by the assembly. He can return a bill to the government with his objections or observations and if the assembly clears it for a second time, he can either give his consent or forward the bill for the President’s consideration. And he can withhold the bill, withholding has been defined by the Supreme Court as the bill falls through, and the bill is dead. When the bill is ‘withhold’, the bill is dead. However, the Constitution does not provide a timeframe for the governor to approve bills.

Waste-to-Energy Plant
The Bowenpally Vegetable Market in Hyderabad has implemented an innovative waste management system. The market collects nearly 10 tons of waste every day, which is now converted into bioelectricity, biogas, and bio-manure through a waste-to-energy plant. The unsold and rotten vegetables are shredded and crushed into pulp, which undergoes anaerobic digesters to produce biogas. The biogas is collected and stored in balloons and used for cooking and powering the market facilities through a biogas generator. Bio-manure is also produced as a by-product of the process. The waste generated, which previously ended up in landfills, is now used to generate approximately 500 units of electricity and 30 kg of biofuel per day.
The waste-to-energy plant also generates employment for women by providing opportunities for them to work in various roles. The plant is funded by the Department of Biotechnology and Department of Agriculture Marketing Telangana is set up under the guidance and patented technology of CSIR-IICT. The waste-to-energy plant is not only an innovative solution to the waste management problem but also a significant step towards sustainable development.
