1. Cluster Bombs: An Overview
Iran's reported deployment of a cluster bomb in a missile attack on Israel has renewed global concerns about the dangers these weapons pose.
What are Cluster Bombs?
Cluster bombs, or cluster munitions, are explosive weapons that release numerous smaller explosives—called submunitions or bomblets—across a wide area before impact. These bomblets are designed to detonate on contact or after a brief delay. However, a significant number often fail to explode immediately, remaining active for months or even years, thereby posing a lasting threat to civilian populations.
These weapons can be delivered by air or launched from the ground, capable of saturating large areas, making them especially deadly in urban or densely populated zones. Submunitions, typically the size of grenades and equipped with fins or streamers for stability, target both personnel and unarmoured vehicles. Some variants, such as the US-manufactured DPICM, have dual-purpose charges for enhanced damage.
The primary controversy lies in their high failure rate—or “dud rate”—with estimates ranging from 2% to 40%. This effectively transforms unexploded bomblets into landmines, posing serious risks long after conflicts end. These weapons cannot distinguish between military targets and civilians, amplifying their humanitarian impact in populated regions.
The Convention on Cluster Munitions (CCM), which came into force in 2010, prohibits the use, development, stockpiling, and transfer of such weapons. While 111 countries and 12 entities have ratified the treaty, several major powers—including the US, Russia, China, Israel, Iran, and India—have not joined. According to the UN, 99% of stockpiles declared under the treaty have been destroyed.
2. Bhashini Platform: Bridging India’s Language Divide
A recent agreement between the Ministry of Panchayati Raj and the Ministry of Electronics and Information Technology’s Bhashini initiative aims to enhance linguistic inclusivity across the country.
What is the Bhashini Platform?
BHASHINI (BHASHa INterface for India) is an AI-driven language translation initiative by the Ministry of Electronics and Information Technology (MeitY), under the National Language Translation Mission. It seeks to create a National Public Digital Platform that supports the development of citizen-centric language services and applications.
The platform facilitates translation of content into various Indian languages and aims to significantly expand online content in Indian languages—especially in governance, science, and public policy—encouraging broader internet usage in native tongues. BHASHINI leverages advanced technologies like Artificial Intelligence and Natural Language Processing (NLP) to provide seamless access to content and digital services in users' preferred languages.
Implemented by the Digital India BHASHINI Division under the Digital India Corporation (a Section 8 company of MeitY), the platform currently supports over 22 Indian languages. Its features include text and speech translation, optical character recognition (OCR), video and document translation, language detection, and voice-based UPI payments.
BHASHINI also offers an app for public use and APIs for startups to integrate language services, such as multilingual chatbots. A special “Bhasadaan” section allows users to contribute to language datasets via crowdsourcing initiatives. The platform has partnered with the National Payments Corporation of India (NPCI) to enable voice-based digital payments in Indian languages.

7. What are Hypnic Jerks?
Hypnic Jerks are sudden, involuntary muscle contractions that occur during the early stages of sleep.
Overview:
-
Also known as sleep starts, hypnic jerks affect over 80% of the population.
-
They typically occur during the transition from wakefulness to sleep, particularly in the first or second stages.
-
The brain, as it begins to relax, may misinterpret muscle relaxation as a sensation of falling, triggering a quick muscle contraction.
-
Though harmless, their frequency and intensity can vary among individuals.
Causes:
-
Elevated stress and anxiety levels
-
Excessive caffeine intake
-
Sleep deprivation
Management:
-
Stress-reduction techniques like meditation, yoga, and breathing exercises can help.
-
Limiting caffeine, maintaining consistent sleep schedules, and regular physical activity are also effective strategies.
