Supreme Court asks West Bengal government to implement one nation-one ration card immediately
- The Supreme Court has asked the West Bengal government to implement the One Nation One Ration Card scheme “immediately” to help beneficiaries, especially migrant workers, avail of subsidized food commodities from anywhere in the country.
- Apart from West Bengal, Assam, Chhattisgarh, and Delhi are the other states yet to implement it.
One Nation One Ration Card Scheme
- Currently, ration cardholders can avail their entitlement of subsidized foodgrains under the National Food Security Act, only from the designated Fair price shop (FPS) within the concerned state.
- If a beneficiary were to shift to another state, he/she would need to apply for a new ration card in the second state.
- Thus, geographical location is one of the hindrances that migrant workers face in order to claim their quota of grains and subsequently get denied their right to food.
- To address the grim state of food security in the country and combat the problem of hunger, the government has started the ‘One Nation, One Ration Card’ facility.
Benefits of the Scheme
- Under the ONORC, the beneficiaries from one state can get their share of rations in other states where the ration card was originally issued.
- After the scheme gets implemented at the national level, any Public Distribution System (PDS) recipient can use their ration cards at any PDS shop across the country.
- ONORC seeks to provide universal access to PDS food grains for migrant workers.
- However, the beneficiary would be able to avail themself only of the benefits provided by the Union Government.
- CHIME telescope yields unprecedented results
- Scientists with the Canadian Hydrogen Intensity Mapping Experiment (CHIME) Collaboration, who include researchers at the Pune-based Tata Institute for Fundamental Research (TIFR) and the National Centre for Radio Astrophysics (NCRA), have assembled the largest collection of fast radio bursts (FRBs) in the telescope’s first FRB catalogue.
- FRBs are oddly bright flashes of light, registering in the radio band of the electromagnetic spectrum, which blazes for a few milliseconds before vanishing without a trace.
- These brief and mysterious beacons have been spotted in various and distant parts of the universe, as well as in our own galaxy.
- Their origins are unknown and their appearance is highly unpredictable
- The Maharashtra govt’s proposed amendment for the protection of ‘heritage trees’
- The Maharashtra government will make amendments to the Maharashtra (Urban Areas) Protection and Preservation of Trees Act of 1975, to introduce provisions for the protection of ‘heritage trees’.
- Under the proposed amendment, a tree with an estimated age of 50 years or more shall be defined as a heritage tree.
How is the age of the tree determined?
- The most common method of determining the age of the tree is Dendrochronology – or tree-ring dating also called growth rings.
- Each year, roughly a tree adds to its girth, the new growth is called a tree ring. By counting the rings of a tree, the age can be determined.
- Venus wins stunning 3rd new mission, this time from Europe
- On June 2, NASA Administrator Bill Nelson announced that the agency would pursue two new Venus missions dubbed DAVINCI+ and VERITAS, aiming to launch the spacecraft between 2028 and 2030.
- On June 10, the European Space Agency (ESA) joined the rush to Venus, announcing that it would launch a mission dubbed EnVision to the planet in the early 2030s.
Objectives of the Mission
- The mission was chosen over an astrophysics project called Theseus, which would have studied very distant gamma-ray bursts and other transient events, with the goal of understanding the life cycle of the very first stars, according to ESA.
Other Mission’s to Venus
- NASA’s VERITAS mission (short for Venus Emissivity, Radio Science, InSAR, Topography, and Spectroscopy) will generate a global map of the topography of Venus. The data will be a vital upgrade compared to what we have from NASA’s Magellan mission, which used a much older version of the technology to map Venus between 1989 and 1994.
- DAVINCI+ (Deep Atmosphere Venus Investigation of Noble Gases, Chemistry and Imaging) will be the only one of these new missions to venture through Venus’ atmosphere.
- The spacecraft includes a main orbiter plus a probe that will travel all the way down through the planet’s atmosphere to its surface, gathering measurements of how the atmosphere changes with depth.
