Dak Sewa App - Citizen-Facing Platform

• Dak Sewa is a citizen-centric mobile platform that provides 24x7 access to postal services.

• It allows article tracking, online booking and complaint registration and monitoring.

• It provides Post Office and PIN Code locator facilities.

• It also includes financial calculators for postal financial products.

• It supports 23 Indian languages through the BHASHINI platform.

Quick Recall

• Dak MITRA -> Branch Post Office operations.

• Dak Sewa -> citizen-facing postal services.

• Dak MITRA developed by -> CEPT.

• Dak Sewa language support -> 23 Indian languages via BHASHINI.

Indian Star Tortoise (Geochelone elegans)

Why in News: 216 rescued Indian Star Tortoises were recently rehabilitated in Tadoba-Andhari Tiger Reserve, Maharashtra.

About the Species

• The Indian Star Tortoise is a medium-sized terrestrial tortoise native to the Indian subcontinent.

• It gets its name from the distinctive star-shaped pattern on its shell.

Habitat and Distribution

• It inhabits dry grasslands, scrub forests, semi-arid regions and thorny bush habitats.

• It is mainly found in western India and southern India, especially Kerala, Karnataka and Tamil Nadu, as well as Sri Lanka.

Physical Features

• The shell has radiating yellow star-like patterns on a dark background, which help in camouflage.

• It can grow up to about 10 inches or 25 cm in length.

• Females are generally larger than males.

Behaviour and Diet

• It is largely solitary and crepuscular, meaning it is most active in the early morning and late afternoon.

• It remains inactive during extremely hot, dry or cold conditions but does not hibernate.

• It is mainly herbivorous and feeds on grasses, leaves, flowers, fruits and succulent plants.

• Its wild lifespan is approximately 35-80 years.

Conservation Status

• IUCN Red List -> Vulnerable (VU).

• CITES -> Appendix I; international commercial trade is generally prohibited.

Quick Recall

• Scientific name -> Geochelone elegans.

• IUCN -> Vulnerable.

• CITES -> Appendix I.

• Behaviour -> solitary and crepuscular.

Mission CosmoCube

Why in News: An international team of scientists announced that Mission CosmoCube could help study faint radio signals from the early universe.

What is CosmoCube?

• CosmoCube is a proposed suitcase-sized satellite mission designed to study the Cosmic Dark Age - the period before the first stars and galaxies formed.

• It aims to detect ancient radio signals from the early universe.

• The mission is being developed by an international team led by the University of Cambridge, United Kingdom.

Main Aim

• Detect the faint 21-centimetre hydrogen line emitted more than 13.5 billion years ago.

• Study conditions that existed before the formation of the first stars and galaxies.

How It Will Work

• The satellite will orbit the Moon.

• It will use the far side of the Moon as a natural shield from radio interference originating on Earth.

• During each two-hour lunar orbit, it will spend about 40 minutes behind the Moon collecting low-frequency radio signals.

• Onboard systems and mathematical models will filter interference from the spacecraft, the Milky Way and other background radio sources.

Why It Matters

• It may help scientists study the Cosmic Dark Age, one of the least understood periods in cosmic history.

• Its observations may provide clues about the role of dark matter in bringing matter together to form the first stars and galaxies.

• Despite its compact size, it is expected to carry a lightweight radio antenna and precision navigation and positioning systems.

• Proposed mission duration -> two years.

Quick Recall

• CosmoCube -> proposed lunar-orbiting, suitcase-sized mission.

• Target signal -> 21-cm hydrogen line.

• Observation shield -> far side of the Moon.

• Proposed duration -> two years.

Smew (Mergellus albellus)

Why in News: Assam's Laokhowa Wildlife Sanctuary recorded the Smew, a rare migratory waterbird, for the first time.

About the Bird

• Smew is a medium-sized migratory duck belonging to the Anatidae family.

• It was formally described in 1758 by Swedish naturalist Carl Linnaeus.

Range and Habitat

• It breeds in the northern taiga forests of Europe and Asia.

• It winters in the Baltic Sea region, Black Sea region, Great Britain, Caspian Sea region, East China, Korea and Japan.

• In India, it is an occasional winter visitor.

• It occurs in freshwater lakes, reservoirs, flooded forests, ice-free rivers, sheltered bays, estuaries, lagoons and tidal creeks.

Identification

• It has a narrow bill with tooth-like edges and a hooked tip, adapted for catching fish.

• Male -> predominantly white, with a black eye mask and black back.

• Female -> grey body, reddish-brown head and white cheek patches.

• In flight, it shows striking black-and-white wing patterns.

Feeding and Conservation

• It is a diving duck and catches prey by diving below the water surface.

• It can swim underwater while pursuing fish and other aquatic prey.

• IUCN Red List -> Least Concern (LC).

Quick Recall

• Scientific name -> Mergellus albellus.

• Family -> Anatidae.

• India status -> occasional winter visitor.

• IUCN -> Least Concern.
