Eighty-five wild Cape Vultures (Gyps coprotheres), an Old World vulture species that resides exclusively in Southern Africa and is threatened due to dwindling numbers, have returned to South Africa’s Eastern Cape province after three decades.

There are 23 species of vultures globally, divided into two families: Accipitridae, or Old World vultures, comprising 16 species found across Africa, Europe, and Asia, and Cathartidae, or New World vultures, consisting of seven species native to the Americas and the Caribbean.

Vultures play a crucial role in the ecosystem by disposing of carcasses quickly, thereby preventing the spread of diseases such as anthrax, botulism, and rabies among wildlife and humans.

Their absence would lead to an increase in other scavengers, such as feral dogs and rats, which are less efficient at consuming carcasses and can carry diseases harmful to humans and livestock.
NASA is set to launch a new telescope that will create the most colorful map of the cosmos ever made.

The SPHEREx telescope, though relatively small, will provide an enormous amount of knowledge during its short two-year mission. It is an infrared telescope designed to capture spectroscopic images—ones that measure individual wavelengths of light from a source.

By doing so, it will help us understand the formation of the universe, the growth of galaxies throughout cosmic history, and the distribution of water and life-forming molecules in our own galaxy.

The mission, scheduled for launch on February 27, aims to uncover fundamental insights into how the universe came to be and why life exists within it. SPHEREx will specifically focus on identifying water and life-bearing molecules (biogenic molecules) in the gas clouds of our Milky Way galaxy.

In the coldest regions of the galaxy, molecules essential for life—such as water, carbon dioxide, and methanol—are trapped in icy particles. For life to emerge, these icy biogenic molecules must transition from interstellar gas clouds onto planets.

To answer this fundamental question about human existence, scientists need to know where these molecules are located.

By mapping the entire sky, SPHEREx will pinpoint the locations of these molecules not only in our galaxy but also in nearby star systems.

While the James Webb Space Telescope is expected to capture a few thousand such measurements, SPHEREx will generate 8 million new spectroscopic images of life-bearing molecules—revolutionizing our understanding of the cosmos.
The Indira Gandhi National Centre for the Arts (IGNCA), an autonomous institution under the Ministry of Culture, in collaboration with the Satyarthi Movement for Global Compassion, held a dedicated discussion on Diyaslai, the autobiography of Nobel Peace Prize laureate Kailash Satyarthi.

In its 24 chapters, Satyarthi narrates his journey—from being born into the family of a humble police constable in Vidisha to his lifelong struggle for the liberation of children from exploitation, culminating in the honor of receiving the Nobel Peace Prize.
The delimitation of constituencies for the Lok Sabha and State Legislative Assemblies is to be carried out based on the first Census conducted after 2026. The 2021 Census was initially postponed due to the COVID-19 pandemic and later delayed by the Central government.

Delimitation refers to the process of determining the number of seats and defining the boundaries of territorial constituencies in each State for the Lok Sabha and Legislative Assemblies.

It also includes the allocation of reserved seats for Scheduled Castes (SC) and Scheduled Tribes (ST) in these houses. Articles 82 and 170 of the Constitution mandate that the number of seats in the Lok Sabha and State Legislative Assemblies, as well as their division into territorial constituencies, must be readjusted after each Census.

This process is carried out by the Delimitation Commission, which is established through an Act of Parliament. Previous delimitation exercises were conducted after the Censuses of 1951, 1961, and 1971.

The number of seats in the Lok Sabha has remained frozen based on the 1971 Census to promote population control measures, ensuring that States with higher population growth do not gain a disproportionate number of seats.

This freeze was initially imposed by the 42nd Amendment Act until the year 2000 and was later extended by the 84th Amendment Act until 2026.
In February 2025, Madhya Pradesh CM Mohan Yadav released 10 gharials, a critically endangered species, into the Chambal River at the National Chambal Gharial Sanctuary in Morena.

Madhya Pradesh's decades-long conservation efforts have earned it the title of a “gharial state,” as it hosts over 80% of India’s gharial population.

The gharial (Gavialis gangeticus) is a long-snouted, fish-eating crocodilian. In Indian mythology, gharials hold sacred significance and are often depicted as the divine mount of the goddess Ganga.

Historically, threats to gharials included overhunting for skins, trophies, eggs, and their use in traditional medicine. Modern challenges such as dam construction, irrigation canals, siltation, changes in river courses, embankments, sand mining, pollution, and fishing continue to devastate their populations.

Gill nets, in particular, pose a severe threat, killing gharials of all sizes, even in protected areas.

Between 1975 and 1982, India established 16 captive breeding and release centers, along with five dedicated gharial sanctuaries. Today, the species primarily survives in five key refuges: National Chambal Sanctuary (NCS), Katerniaghat Sanctuary, Chitwan National Park, Son River Sanctuary, and Satkosia Gorge Sanctuary.
World Civil Defence Day is celebrated every year on March 1st. The theme for 2025 is "Civil Defence: A Guarantee of Security for the Population."
