Pradhan Mantri Divyasha Kendra Inaugurated in Badaun, Uttar Pradesh

Category: Welfare Schemes

Context:

The Union Ministry of Social Justice & Empowerment has launched the 75th Pradhan Mantri Divyasha Kendra (PMDK) at the Government Medical College in Badaun, Uttar Pradesh.

To date, these centres have served over 1.4 lakh beneficiaries, distributing aids worth approximately ₹179.15 lakh.

Significance:

This initiative facilitates decentralised delivery of services for disability support, tackling the challenges faced by rural populations of distance and accessibility, thereby enabling timely and dignified assistance closer to beneficiaries' residences.

RhoDIS India Programme: Genetic Profiling of Rhino Horns Underway

Category: Environment & Biodiversity

Context:

Scientists have commenced genetic testing of 2,573 rhino horn samples to update the RhoDIS India DNA database.

About RhoDIS India:

Launched in 2016 by the Ministry of Environment in collaboration with the Wildlife Institute of India (WII), WWF India, and state forest departments, the Rhino DNA Indexing System (RhoDIS) is a forensic tool aimed at combating rhino poaching. By creating unique DNA profiles for individual rhinos, RhoDIS aids in wildlife crime investigations, supports legal prosecution, and enhances conservation and population management efforts.

Key Features:

Utilises DNA sequencing to map individual rhino genetic signatures.
Operates using protocols authorised by the MoEFCC.
Rhino horn mainly consists of keratin, a protein similar to human nails and hair, embedded with amino acids and mineral salts.
The Greater one-horned rhino, native primarily to India and Nepal, is recognised by its single horn.

Sigandur Bridge Inaugurated in Karnataka

Category: Infrastructure Development

Context:

The Union Minister of Road Transport & Highways inaugurated the Sigandur Bridge in Karnataka, a vital project improving regional connectivity.

Officially named the Ambaragodlu-Kalasavalli Bridge, this structure spans the backwaters of the Sharavati River in Karnataka's Shivamogga district. At 2.44 km long and 16 meters wide, it stands as India's second-longest cable-stayed bridge, built at a cost of ₹473 crore.

Significance:

This bridge reconnects territories that were cut off following the construction of the Linganamakki Dam in the 1970s. It enhances accessibility to the Sigandur Chowdeshwari Temple, reducing travel time, and boosting both pilgrimage and local economic activity.

About Sharavati River:

The Sharavati is a westward flowing river originating from the Western Ghats, famous for creating the iconic Jog Falls. Its tributaries include rivers such as Nandihole and Haridravathi.

Zographetus mathewi: New Butterfly Species Found in Western Ghats

Category: Biodiversity

Context:

Researchers have identified a new butterfly species in Kerala's Western Ghats, named Zographetus mathewi or the Sahyadri Spotted Flitter.

About the Species:

Belonging to the skipper family (Hesperiidae), this butterfly is the fifth recorded species of the genus Zographetus in India. It thrives in low-altitude forested areas and acts as a vital bioindicator of ecosystem health.

Distinctive Traits:

Characterised by unique male forewing venation, a basal hair tuft, and yellow-ochre wing scaling.

Cysteine: Key Amino Acid Linked to Weight Regulation

Category: Science & Health

Context:

A recent study on mice showed that eliminating cysteine from their diet led to rapid weight loss, highlighting the amino acid's role in metabolism.

About Cysteine:

Cysteine is a sulfur-containing, non-essential amino acid essential for producing collagen, taurine, and glutathione - a potent antioxidant. It supports detoxification, immunity, and skin elasticity.

Dietary Sources:

Found in foods like poultry, eggs, dairy, and whole grains.

Noctilucent Clouds Seen Over Scotland

Category: Geography & Atmosphere

Context:

Unusual sightings of noctilucent clouds have been reported over Scotland, occurring under particular atmospheric summer conditions.

About Noctilucent Clouds:

These clouds form at the highest altitudes, found in the mesosphere around 76-85 km above Earth's surface. Composed of ice crystals that develop on cosmic dust particles, they emit a silvery-blue glow when illuminated by sunlight from below the horizon. Most commonly seen between latitudes 45° and 80°, they appear primarily from May to August in the Northern Hemisphere.

Mhadei Wildlife Sanctuary Under Threat from Tourism Project

Category: Environment

Research indicates that modification of pheromone signaling can help disrupt the swarming behaviour of locusts.

About Pheromones:

These chemical messengers influence behavior within a species and are categorized into four types: releasers (trigger immediate responses), signallers (convey individual identity), modulators (affect emotional states), and primers (induce hormonal changes). Manipulating these signals presents a promising approach for managing locust swarms.
