From UPSC perspective, the following things are important :
Prelims level: Emerging Technologies; Deepfake Technology;
Why in the News?
During the General Elections 2024, the proliferation of AI-generated content (AIGC), including deepfake videos featuring prominent figures like Aamir Khan and Ranveer Singh, raised concerns about misinformation.
What is Deepfake Technology?
- It is a type of Artificial Intelligence used to create convincing images, audio and video hoaxes. Deepfakes often transform existing source content where one person is swapped for another.
- Creating such content involves a technique known as Generative Adversarial Networks (GANs), comprising Artificial Neural Networks.
Legal Safeguards in India:
- The regulations under the IT Act of 2000 and 2021 requires social media intermediaries to promptly remove deepfake content. Failure to do so may result in imprisonment or fines.
- Section 66D: It penalizes individuals for cheating through personation using communication devices or computer resources. (Imprisonment for up to 3 yrs and a fine of up to 1 lakh rupees)
- Rule 3(1)(b)(vii): This rule mandates that social media intermediaries prevent the hosting of content impersonating others.
- Rule 3(2)(b): This rule requires social media platforms to remove such content within 24 hours of receiving a complaint.
|
Significance of Deepfake Technology:
- Promotes Right to Expression: Deepfakes amplify voices of marginalised individuals, enabling them to share important messages. Recently, a video was created to deliver the final message of a journalist killed by the Saudi government, calling for justice.
- Can contribute to the Education System: Online educators use deepfakes to bring historical figures to life for engaging lessons. For example, a video of Abraham Lincoln delivering his Gettysburg.
- Provides Autonomy: Deepfakes empower individuals to control their digital identity and explore new forms of self-expression. For instance, the Reface App.
- Provides a realistic experience: Artists leverage deepfakes for creative expression and collaboration, as seen in Salvador Dali’s interactive museum promotion. Deepfake tech enables realistic lip-syncing for actors speaking different languages, enhancing global accessibility and immersion in films.
- Renovating old memories: Deepfakes aid in restoring old photos, enhancing low-quality footage, and creating realistic training materials for public safety.
What are the limitations of Deepfake Technology?
- Spreading False Information: Deepfakes can purposefully spread misinformation, influencing public opinion or elections, like the videos of politicians/celebrities can manipulate viewers and create confusion about important issues.
- Frauds: Deepfake technology enables impersonation for financial frauds, tricking individuals into revealing sensitive information. They can also fuel harassment, especially targeting women, and lead to psychological distress.
- Accuracy: While no AI detector guarantees 100% accuracy, tools like Originality.ai boast a 99% true positive rate. Detection models report probability scores, allowing for nuanced assessments despite inherent uncertainties.
Future Scope:
- Adversarial AI: Keeping pace with evolving generative AI models poses a significant challenge for content detectors.
- Accessibility and Cost: With increased adoption and advancements, the accessibility and affordability of detection tools are expected to improve.

Prelims level: Auroras and its types, Coronal Mass Ejections/ Solar Storm
Mains level: NA
Why in the news?
- In a rare event, the night sky over Hanle village in Ladakh was illuminated by the northern lights or aurora borealis.
- Concurrently, the southern lights, or aurora australis, were observed in New Zealand and Australia.
What are Auroras?
- Auroras are natural light displays that appear as bright, swirling curtains in the night sky.
- They are typically seen near the Poles but can occasionally be observed at lower latitudes.
- These lights can display a range of colors, including blue, red, yellow, green, and orange, due to the interaction of solar particles with different gases in the Earth’s atmosphere.
- The phenomenon is known as:
- Aurora borealis in Northern Hemisphere and
- Aurora australis in Southern Hemisphere
What causes Auroras?
- Interaction with Earth’s Magnetic Field: As the solar wind approaches Earth, it interacts with the planet’s magnetic field, causing some charged particles to enter the atmosphere near the poles.
- Interaction with Gases: These particles interact with gases in the upper atmosphere, producing colourful flashes of light. Collision with oxygen produces green light, while interaction with nitrogen results in shades of blue and purple.
Reasons for Aurora in Ladakh:
- Intense Solar Activity: Auroras can extend to lower latitudes during periods of intense solar activity, such as solar flares and coronal mass ejections (CMEs).
- The CMEs are from the AR13664 region of the sun that has produced several high-energy solar flares
- Localized magnetic anomalies: Variations in Earth’s magnetic field could potentially influence the occurrence of auroras in specific areas, including regions at lower latitudes.
|
Impact on Tech Infrastructure
- Auroras can pose challenges to space-dependent technologies and operations.
- Disruptions in Global Positioning Systems (GPS), radio communications, flight operations, power grids, and space exploration endeavors may occur during such events.
PYQ:
[2022] If a major solar storm (solar flare) reaches the Earth, which of the following are the possible effects on the Earth?

From UPSC perspective, the following things are important :
Prelims level: Bail and its legal provisions
Why in the news?
The Supreme Court has granted interim bail to Delhi Chief Minister Arvind Kejriwal in the liquor policy case till to campaign for the Lok Sabha elections.
What is Interim Bail?
- Interim bail in India is a temporary release granted to an accused person from custody under Section 439 Cr.
- It can be granted to address urgent matters such as medical emergencies, family crises, or other significant personal issues.
Legal Provisions for Interim Bail
Interim bail in India is NOT explicitly defined under a specific statute but is derived from the discretionary powers granted to courts under various legal provisions.
The most relevant laws and principles include:
- Code of Criminal Procedure, 1973 (CrPC): While the CrPC does not explicitly mention “interim bail,” it provides the framework for granting bail in general. Sections like 437 (bail in non-bailable cases by Magistrate), 438 (anticipatory bail), and 439 (special powers of High Court or Court of Session regarding bail) are used by courts to grant bail, including interim bail, based on judicial discretion.
- Constitutional Provisions: The Constitution of India under Article 21, which guarantees the right to life and personal liberty, is often interpreted to include the right to bail as part of the fair and just legal process.
Back2Basics: What is Bail?
- Bail is the conditional release of a defendant with the promise to appear in court when required.
- The term also means the security that is deposited in order to secure the release of the accused.
- In India’s legal world, the term offense has been categorized as bailable offenses and non-bailable under the Code of Criminal Procedure.
Why need Bail?
- Bail is a fundamental aspect of any criminal justice system.
- A person can defend himself/herself better when he/she is free, thus ensuring free trial.
- The practice of bail grew out of the need to safeguard the fundamental right to liberty.
- Liberty is the right of one whose guilt has not yet been proven.
Types of Bail in India
- Depending upon the sage of the criminal matter, there are commonly three types of bail in India:
- Regular Bail: Granted to a person who has already been arrested and is in custody. This type of bail is provided under Sections 437 and 439 of the Code of Criminal Procedure, 1973 (CrPC). It allows the accused to be released from custody while the trial is ongoing.
- Anticipatory Bail: Under Section 438 of the CrPC, anticipatory bail is a pre-arrest legal process. It is granted when a person apprehends arrest on an accusation of having committed a non-bailable offence. This type of bail ensures that the accused will be released on bail in the event they are arrested.
- Interim Bail: This is temporary bail granted for a short period. Interim bail is often granted to allow the accused some relief until a final decision on their regular or anticipatory bail plea is made.
Conditions for Grant of Bail in Bailable Offences
- Section 436 of the Code of Criminal Procedure, 1973, lays down that a person accused of a bailable offense under IPC can be granted bail if:
- There are sufficient reasons to believe that the accused has not committed the offence.
- There is sufficient reason to conduct a further inquiry in the matter.
- The person is not accused of any offence punishable with death, life imprisonment or imprisonment up to 10 years.
Conditions for Grant of Bail in Non-Bailable Offences
- Section 437 of Code of Criminal Procedure, 1973 lays down that the accused does not have the right to apply for bail in non-bailable offences.
- It is discretion of the court to grant bail in case of non-bailable offences if:
- The accused is a woman or a child, bail can be granted in a non-bailable offence.
- There is a lack of evidence then bail in non-Bailable offenses can be granted.
- There is a delay in lodging FIR by the complainant, bail may be granted.
- The accused is gravely sick.

From UPSC perspective, the following things are important :
Prelims level: FLiRT Covid Variant
Why in the news?
The emergence of new variants KP.2 and KP1.1, known as the FLiRT variants, has raised global concerns.
- Despite vaccination efforts, these variants pose challenges, leading to concerns about a potential rise in COVID-19 cases.
What are the FLiRT Variants of COVID-19?
- KP.2 and KP1.1, dubbed ‘FLiRT’ variants, are descendants of the Omicron JN.1 which spread globally over the winter last year.
Features and Differences from Other Variants
- New Spike Mutations: The FLiRT group includes two specific mutations that are believed to enhance the virus’s ability to infect human cells.
- Transmission and Evasion: Preliminary studies suggest that KP.2, the more prevalent of the two, may possess enhanced capabilities to evade immune responses generated by vaccines and previous infections.
Are FLiRT Variants Riskier than JN.1?
- Increased Immune Evasion: Research indicates that KP.2 shows a significant ability to escape immunity from both the latest vaccines and previous infections.
- Reproduction Number: The reproduction number of KP.2 may be higher than that of JN.1, indicating a potentially greater ability to spread.
- No definitive evidence: While there’s no definitive evidence that FLiRT variants cause more severe illness, their ability to circumvent immune defences can lead to more infections and, by extension, potential increases in hospitalizations.

From UPSC perspective, the following things are important :
Prelims level: Cloud Seeding, Seeding Agents
Why in the news?
The Uttarakhand government faced scrutiny from the Supreme Court following Forest fires that claimed lives in the state.
- Justices highlighted the inefficacy of relying solely on cloud-seeding or rain gods to address the crisis.
Case Study: Experimenting Artificial Rain in India
- A recent study published in the Bulletin of the American Meteorological Society (BAMS) highlighted the success of a cloud seeding trial in Maharashtra’s Solapur region, which resulted in an 18% increase in rainfall compared to normal patterns.
- Scientists from the Indian Institute of Tropical Meteorology in Pune and other institutes conducted this study.
- The experiment targeted warm convective clouds with a height above zero degrees Celsius, releasing calcium chloride particles to stimulate rainfall.
- Spanning from 2017 to 2019, the experiment analyzed 276 clouds using advanced tools like automatic rain gauges, radars, radiometers, and aircraft.
- Glaciogenic seeding, attempted in clouds containing both ice and water, did not significantly impact rainfall at the seeding location, according to the study’s findings.
|
About Cloud-Seeding
- Cloud seeding is a weather modification technique aimed at altering precipitation patterns by dispersing substances into clouds to stimulate rainfall or snowfall.
- It is used to mitigate hail, disperse fog, and either induce precipitation or prevent it from occurring in subsequent days.
- It involves the dispersal of substances like silver iodide, potassium iodide, dry ice, and hygroscopic materials such as table salt into the atmosphere.
- Techniques include:
- Static seeding: promotes ice particle formation in supercooled clouds, and
- Dynamic seeding: enhances convective cloud development through the release of latent heat.
- Dispersion methods range from aircraft and ground-based generators to newer approaches like drones delivering electric charges or infrared laser pulses.
Limitations: Impact on Environment and Health
- Concerns persist regarding the potential accumulation of seeding agents in sensitive ecosystems, although detailed studies have shown negligible impacts.
- The chemicals used, such as silver iodide, may potentially damage the environment and cause health issues like iodine poisoning in high concentrations

From UPSC perspective, the following things are important :
Prelims level: Diseases; Widal Test, Salmonella Typhi Bacteria;
Mains level: NA
Why in the news?
Patients with fever in India often undergo testing and treatment for typhoid fever, primarily relying on the Widal test.
- The Widal test, though widely used, has several limitations that affect its accuracy and reliability.
Typhoid diagnosis using Widal Test
- The Widal test is used primarily to diagnose typhoid fever.
- Typhoid fever, caused by Salmonella Typhi and related bacteria, presents with symptoms like high fever, stomach pain, weakness, and gastrointestinal issues.
- It detects antibodies in the patient’s blood against the O (somatic) and H (flagellar) antigens of Salmonella Typhi.
- Procedure:
- The presence of these antibodies is detected through an agglutination reaction.
- The test involves serial dilution of the patient’s serum.
- The highest dilution at which agglutination occurs indicates the antibody titer, with higher titers suggesting an active infection.
Diagnostic Challenges:
- The gold standard for diagnosing typhoid involves isolating the bacteria from blood or bone marrow cultures, which is time-consuming and resource-intensive.
- Widal test is commonly used due to its convenience and accessibility. However, the Widal test’s interpretation is complicated by factors like the need for multiple serum samples, variations in cutoff values, and potential cross-reactivity with antibodies from other infections or vaccines.
Challenges with Widal Test:
- Impractical: A single positive Widal test does not confirm typhoid.
- Complicated result interpretation: High background antibody levels and variability in test cutoff values.
- Cross-reactivity with antibodies from other infections and false negatives due to prior antibiotic therapy undermine test reliability.
Consequences of Widal Test Use:
- Erroneous results obscure the true burden of typhoid in India, leading to inappropriate treatment and financial strain on patients.
- Overuse of antibiotics based on Widal test results contributes to antimicrobial resistance, exacerbating the challenge of treating typhoid.
