About the Sangita Kalanidhi Award
- Sangita Kalanidhi is considered the highest honour in Carnatic classical music, awarded annually for exceptional contribution to the field.
- Origin: Considered the highest accolade in the field of Carnatic music, it came into existence in 1942.
- Carnatic classical music originated in South India from ancient Hindu devotional traditions during the 12th–17th centuries.
- It is characterised by kriti compositions, raga–tala system, improvisation, and emphasis on vocal performance with instruments like veena and mridangam
- Institution: The award is presented by The Music Academy, Chennai, an institution that emerged from the 1927 All India Congress Session in Madras, promoting classical arts.
- Award Components: The honour includes a gold medal and a “birudu patra” (citation) and recognition at the Academy’s annual December Music Conference.
- Selection and Criteria: The award recognises eminent Carnatic musicians, scholars, or composers for lifetime contributions to performance, scholarship, and propagation of classical music.
- Role in Music Tradition: Recipients traditionally preside over the academic sessions of the annual conference, contributing lectures and discussions on Carnatic music traditions.
About Jayanthi Kumaresh
- Jayanthi Kumaresh is a leading Saraswati veena exponent from the renowned Lalgudi musical lineage, trained under maestros such as S. Balachander.
- Musical Contributions: She has played a key role in reviving the popularity of the veena, presenting it globally through concerts, collaborations, and innovative compositions.
- Collaborations and Recognition: Kumaresh has collaborated with legendary musicians, including Zakir Hussain, expanding Carnatic music’s reach across classical and fusion platforms.
- Role in Carnatic Music: Through performances, teaching, and research, she has helped modernise veena presentation while preserving traditional Carnatic aesthetics.
About the Veena
- The Veena is an ancient plucked string instrument central to Carnatic Music, known for its rich tone and ability to produce intricate melodic ornamentations.
- Origin and Early History: The Veena traces its origins to the Vedic period (around 1500 BCE), evolving from early harp-like instruments mentioned in ancient Sanskrit texts and temple traditions.
- Structure and Playing Technique: The Saraswati Veena features a wooden resonator, long neck, 24 frets, four melody strings and three drone strings, played horizontally while seated cross-legged.
- Evolution of the Modern Form: The modern Thanjavur Veena design with fixed frets developed during the 17th-century rule of Raghunatha Nayak in Tamil Nadu.
- Cultural and Religious Significance: The Veena is closely associated with Saraswati, symbolising wisdom, music, and artistic learning in Indian cultural traditions.
Trisulfide Metathesis Reaction
Context: Scientists at Flinders University discovered a new trisulfide metathesis reaction, where sulfur chains exchange partners spontaneously at room temperature without heat, light, or catalysts.
About Trisulfide Metathesis Reaction
- The trisulfide metathesis reaction is a newly discovered chemical process where molecules containing three sulfur atoms (R–S–S–S–R) exchange molecular fragments rapidly under mild conditions.
- Mechanism of the Reaction
- Sulfur Chain Exchange: Two trisulfide molecules exchange attached molecular groups, forming new molecular combinations through a partner-swapping process known as metathesis.
- Occurs Under Mild Conditions:Unlike typical sulfur reactions requiring heat, light, or catalysts, this reaction occurs spontaneously at room temperature in certain solvents such as dimethylformamide.
- Rapid and Reversible Process: The reaction reaches equilibrium within seconds, and the bond exchange remains fully reversible, enabling repeated molecular rearrangements.
- Significance of the Discover:
- New Pathways in Drug Development: Scientists used the reaction to modify anti-tumor compounds such as calicheamicin, demonstrating potential applications in pharmaceutical design.
- Development of Recyclable Materials: The reaction enabled creation of novel plastics linked by trisulfide bonds, which can be easily broken down and recycled into original components.
- Advances in Materials and Molecular Chemistry: Fast and controllable sulfur exchange may help design self-rearranging molecules, smart polymers, and responsive materials for biotechnology and advanced manufacturing.
Herpes Simplex Virus (HSV)
Context: An outbreak of Herpes Simplex Virus infected 92 inmates and caused seven deaths at Jalpaiguri Central Correctional Home, West Bengal.
About Herpes Simplex Virus (HSV)
- Herpes Simplex Virus is a common viral infection belonging to the Herpesviridae family.
- Two Main Types:
-
- HSV-1: Mainly causes oral herpes (cold sores around the mouth).
- HSV-2: Mainly causes genital herpes.
- Mode of Transmission: Spreads through direct skin-to-skin contact, sexual contact, or contact with infected bodily fluids.
- Symptoms: Can cause painful blisters or sores, itching, fever, and swollen lymph nodes; many infections may remain asymptomatic.
- Latency: The virus can remain dormant in nerve cells and reactivate periodically, causing recurrent outbreaks.
- Complications: In severe cases, it may lead to conditions such as Encephalitis (inflammation of the brain), which can be life-threatening.
- Treatment: No permanent cure; antiviral medicines can reduce symptoms and prevent frequent outbreaks.
- Prevention: Includes avoiding direct contact with active sores, practicing safe sex, and maintaining good hygiene.
Sujal Gaon ID
Context: Sujal Gaon ID was launched by the Union Ministry of Jal Shakti to digitally map rural drinking water supply schemes across India.
About the Sujal Gaon ID
