Daily Current Affairs: Vultures, Space & Science

📅 Date: 7 January 2026 (Wednesday)

Welcome to today's detailed analysis. We explore significant environmental strides with vulture conservation in Maharashtra, delve into astrophysics with the W Ursae Majoris star, understand the future of materials engineering, and examine India's strategic projects in Bhutan. Let's begin.

1. Environment: Vulture Release in Melghat Tiger Reserve

In a major conservation effort, the Bombay Natural History Society (BNHS) has released 15 critically endangered Indian vultures into the wild at the Melghat Tiger Reserve in Maharashtra. This move aims to repopulate the species, which plays a vital role as nature's cleanup crew.

2. Space: Study of W Ursae Majoris Star

Indian astronomers from the Aryabhatta Research Institute of Observational Sciences (ARIES) have made significant observations of the W Ursae Majoris (W UMa) star system. They utilized data from the Devasthal Fast Optical Telescope and NASA’s TESS mission.

What is W Ursae Majoris?

It is a prototype of a class of Eclipsing Binary Stars. In this system, two stars are so close to each other that they touch, sharing a common envelope of material. This results in a "peanut" shape.

• Location: It lies in the constellation of Ursa Major (The Great Bear).
• Significance: Studying these stars helps astronomers understand the evolution of binary star systems and mass transfer between stars.

3. Science & Tech: The Future of Biomaterials

As the world shifts away from plastics and harmful synthetics, Biomaterials are emerging as the new frontier in materials engineering. These materials are crucial for a sustainable future across packaging, textiles, and healthcare.

Understanding Biomaterials

Biomaterials are substances (natural, synthetic, or hybrid) designed to interact safely with biological systems (like the human body or environment). They can be derived from biological sources or engineered to replace conventional materials.

The Three Categories:

1. Drop-in Biomaterials: Chemically identical to petroleum-based materials but made from bio-sources (e.g., Bio-PET). They fit into existing manufacturing systems.
2. Drop-out Biomaterials: Chemically different materials requiring new processing methods (e.g., Polylactic Acid or PLA).
3. Novel Biomaterials: These offer brand new properties not found in traditional materials, such as self-healing capabilities or bioactive implants.

4. Infrastructure: Bridging Sagar Island

The West Bengal government has laid the foundation stone for a 5-km-long bridge over the Muriganga River. This bridge will connect Sagar Island to the mainland, easing travel for millions of pilgrims.

Significance of Sagar Island

• Location: Situated in the Ganges delta, about 100 km south of Kolkata. It is part of the Sundarbans but lacks the typical mangrove forests or tiger population.
• Cultural Importance: It hosts the Ganga Sagar Mela every mid-January (Makar Sankranti). This is the second-largest fair in the world after the Kumbh Mela.
• Pilgrimage: Devotees visit the island to take a holy dip at the confluence of the Ganges and the Bay of Bengal and to worship at the Kapil Muni Temple.

5. International Relations: Wangchhu Hydro Project in Bhutan

Strengthening India-Bhutan energy ties, the Adani Group has commenced work on the 570 MW Wangchhu Hydro Electricity Project.

• Project Type: Run-of-River hydropower project.
• Location: Chukha District, Bhutan (on the Wangchu River).
• The River: The Wangchu River flows into India where it is known as the Raidāk River, a tributary of the Brahmaputra.
• Strategic Model: Developed by a joint venture between Adani Power (India) and Druk Green Power Corporation (Bhutan). The power generated will serve Bhutan in winters and be exported to India in summers.

6. Physics Phenomenon: The Mpemba Effect

It sounds impossible, but hot water can freeze faster than cold water! Researchers from JNCASR have used supercomputers to simulate and prove this paradoxical phenomenon known as the Mpemba Effect.

• History: First described by Aristotle, but popularized in modern times by a Tanzanian student, Erasto Mpemba, in 1969.
• Why does it happen? Theories include:
  • Evaporation: Hot water evaporates faster, reducing mass and losing heat.
  • Convection: Stronger currents in hot water transfer heat more efficiently.
  • Frost: Cold water may form an insulating frost layer that slows freezing.

7. Geopolitics: Advisory on Travel to Iran

Due to ongoing protests and instability, India has issued an advisory urging nationals to avoid non-essential travel to Iran.

Iran: A Geopolitical Key Player

• Location: West Asia.
• Capital: Tehran.
• Borders: Shares land borders with Pakistan, Afghanistan, Turkmenistan, Azerbaijan, Armenia, Turkey, and Iraq.
• Maritime: Bordered by the Caspian Sea (North) and the Persian Gulf/Gulf of Oman (South).
• Alliances: It is a member of SCO, OPEC, and BRICS.

8. Governance: SHINE Scheme launched by BIS

On its 79th Foundation Day, the Bureau of Indian Standards (BIS) launched the SHINE Scheme.

• Objective: To empower women through education and awareness about quality standards and certification.
• Static GK: The ISI Mark is the certification mark used by BIS for industrial products in India.
