◎ The species is small in size and grows to a length of 7 cm, it bears lateral line scales and pre-dorsal scales. ◎ It found to use both as food and as an aquarium draw. ◎ Physical characteristics ➔ included a protractible mouth, a pair of maxillary barbels (a sensory organ near the snout), 24-25 lateral line scales and 10 pre-dorsal scales. ◎ They are purely freshwater fishes.
◎ It is a subordinate organization of the Ministry of Environment, Forest and Climate Change and was established in 1916. ◎ Functions ➔ It is a national centre for faunistic survey and exploration of the resources leading to the advancement of knowledge on the exceptionally rich faunal diversity of the country. ◎ Headquarters➔ at Kolkata and 16 regional stations.
International Commission of Zoological Nomenclature ◎ Functions ➔ It regulates a uniform system of zoological nomenclature ensuring that every animal has a unique and universally accepted scientific name.

◎ It creates and revises the International Code of Zoological Nomenclature. ◎ It is based in the Lee Kong Chian Natural History Museum, National University of Singapore.
2)Ramkinkar Baij
Ministry of Culture’s has organised virtual tour titled “Ramkinkar Baij | Journey through silent transformation and expressions” to commemorate his 115th Birth Anniversary.
◎ Ramkinkar Baij (1906-1980), one of the most seminal artists of modern India, was an iconic sculptor, painter and graphic artist. ◎ He was born in Bankura, West Bengal. ◎ In 1925, he made his way to Kala Bhavana, the art school at Santiniketan and was under the guidance of Nandalal Bose.

◎ Encouraged by the liberating, intellectual environment of (Tagore’s) Santiniketan, his artistic skills and intellectual horizons blossomed, thus acquiring greater depth and complexity.
◎ His works➔ ◎ He assimilated the idioms of the European modern visual language and yet was rooted in his own Indian ethos. ◎ He experimented restlessly with forms, moving freely from figurative to abstract and back to figurative. ◎ His themes were steeped in a deep sense of humanism and an instinctive understanding of the symbiotic relationship between man and nature.

◎ Both in his paintings and sculptures, he pushed the limits of experimentation and ventured into the use of new materials. ◎ For instance, his use of unconventional material, for the time, such as cement concrete for his monumental public sculptures set a new precedent for art practices. ◎ Awards and honours➔ ◎ He was invited to participate in the Salon des Réalités Nouvelles in 1950 and in the Salon de Mai in 1951. ◎ In 1970 - Padma Bhushan for his irrefutable contribution to Indian art. ◎ In 1976 he was made a Fellow of the Lalit Kala Akademi. ◎ In 1976, he was conferred the honorary Doctoral Degree of ‘Desikottama’ by Visva Bharati.
3)ANtarctic Impulsive Transient Antenna or ANITA
Designed by NASA, the ANITA instrument is a radio telescope which is used to detect ultra-high energy cosmic-ray neutrinos from a scientific balloon flying over Antarctica. ◎ ANITA is also the first NASA observatory for neutrinos of any kind.

◎ It involves an array of radio antennas attached to a helium balloon which flies over the Antarctic ice sheet at 37,000 meters. ◎ How does ANITA detect Neutrinos ➔ The ANITA instrument detects these ultra-high energy neutrinos by use of the Askaryan effect. ◎ Askaryan Effect ➔ It predicts the production of a coherent radio emission from the cascade of particles produced in a high-energy particle interaction. ◎ How many ANITAs? ➔ ANITA-I was launched in 2006–07 and ANITA-IV was launched in 2016.

👉 ◎ A neutrino is a subatomic particle very similar to an electron. ◎ But it has no electrical charge and a very small mass, which might even be zero. ◎ Neutrinos are one of the most abundant particles in the universe. ◎ Because they have very little interaction with matter, they are incredibly difficult to detect.
4)CoAST India (Collaboration/Covid Action Support Group) Platform
It is a GIS-enabled dashboard that includes an India map reflecting the movement of migrants in real time on their long journeys, often on foot, along with facilities and relief organisations on their routes. ◎ It is a collaboration with Anand-based Forest Ecological Security (FES) as its main nodal point.
CoAST India (Collaboration/Covid Action Support Group) Platform
👉
◎ How it work?➔ ◎ It draws information from 55 organisations on the ground, mostly in villages, and aims to make such data available so that it would enable governments and small local civil society groups to be of assistance. ◎ The map matches “time and spatial data, on administrative facilities in the area, transportation and healthcare facilities of an area and summaries, on the fly, in real time of people passing by.
CoAST India (Collaboration/Covid Action Support Group) Platform
👉 ◎ What is it? ➔ It is India’s first socio, economic and ecological open-source integrated Geospatial data platform. ◎ Function➔ The observatory is designed to supplement local level decision making by village communities, Panchayats, NGOs and government officials. ◎ Structure ➔ It has the ‘India Data Platform’ at its core, which is built on open source and brings together data on over 1,600 parameters, ranging from village to national level in the form of maps, graphs, tables and infographics. ◎ Benefit ➔ It is freely available for civil society organizations, students, government departments and citizens.
