About Rare earth elements (REE):- IMAGE SOURCE: imgurl:https://www.insightsonindia.com/wp-content/uploads/2019/12/Rare_Earth_Elements-300×232.jpg?is-pending-load=1 – Bing Rare earth elements are a set of seventeen metallic elements in the periodic table. The 17 Rare Earths are cerium (Ce), dysprosium (Dy), erbium (Er), europium (Eu), gadolinium (Gd), holmium (Ho), lanthanum (La), lutetium (Lu), neodymium (Nd), praseodymium (Pr), promethium (Pm), samarium (Sm), scandium (Sc), terbium (Tb), thulium (Tm), ytterbium (Yb), and yttrium (Y). They are characterized by high density, high melting point, high conductivity, and high thermal conductance. They do not occur in a free state rather are found in mineral oxide ores. They occur abundantly but are often not concentrated enough to undertake viable extraction. Uses of Rare earth elements:- They are widely used in high technology owing to their luminescent and catalytic properties. Neodymium, is a critical component for permanent. Aerospace and Defence: it is used in precision-guided munitions in missiles, high-power sonar on ships and submarines, stealth helicopters, etc. Health care: are used in medical imaging devices, such as MRIs, and modern surgical machines. Clean Energy: is used in wind turbines, electric car batteries and energy-efficient lights (LEDs and CFLs). Nuclear Energy: these are useful for controlling nuclear reactions and are used in control rods. Electronics: Used as phosphors in cathode ray tubes, fluorescent lamps and X-ray intensifying screens. Chemicals, Oil Refining, and manufacturing: Make the refining of crude oil into gasoline more efficient and are used in many speciality metal alloys. Europium is necessary for LED bulbs and colour television screens.  Samarium is used in optical lasers. India’s situation:- India is almost 100% import-dependent for most rare earth. However, India possesses the 5th highest reserves of rare earth in the world In India, rare earth minerals like ilmenite, sillimanite, garnet, zircon, monazite, and rutile, collectively are found and these are called Beach Sand Minerals (BSM).

Legal notice Syllabus Prelims –Polity Context: Recently, Netflix sent a legal notice regarding the sitcom ‘The Big Bang Theory’s‘ derogatory reference to Madhuri Dixit. About legal notice:- IMAGE SOURCE: What You Need to Know About a Legal Notice? (vakilsearch.com) A legal notice is a formal written communication between the parties. Through a legal notice, the sender notifies the recipient about his intention of undertaking legal proceedings against the latter. A legal notice also helps in making the receiving party aware of the grievances of the sender. It works as a last warning to the receiver to fulfil a certain condition if he does not want a court battle. It is a tool to save time and cost of litigation as it opens the door for the parties to settle the matter through negotiation, mediation or arbitration. It is used in a wide variety of situations:- In Consumer Forums: In case, a faulty product or service is provided to a person he or she can send a legal notice to the concerned person and ask him to rectify the deficiencies. Disputes related to property such as partition, eviction or issues relating to possession of the property. Loan Defaulters: Under the Securitisation and Reconstruction of Financial Assets and Enforcement of Securities Interest Act, 2002 (SARFAESI Act), the debt recovery proceedings begin by sending a legal notice to the defaulters. Cases under the Negotiable Instruments Act: In case of dishonour of cheque, the aggrieved can send a legal notice for recovery of payment. Money Recovery Cases: The first step in money recovery cases is sending a legal notice to the concerned person.

About Earth4All Initiative:- Earth4All is a collective initiative of leading economic thinkers, scientists, and advocates. It is convened by The Club of Rome, the Potsdam Institute for Climate Impact Research, the Stockholm Resilience Centre and the Norwegian Business School. It is guided by a Transformational Economics Commission, made up of economic thinkers from across the globe to explore new economic thinking and test the model outcomes. Its global campaign aims to make the Earth4All vision a reality, advocating for governments to adopt policies that will enable resilient and healthy societies. Findings of the Report:- The researchers advance two scenarios: Too Little, Too Late: predicts that if economic development continues as it has in the last five decades, the world’s population would peak at 8.6 billion in 2050, and decline to 7 billion by 2100. The Giant Leap: the researchers conclude that the population will peak at 8.5 billion by 2040 but then rapidly decline to around 6 billion by 2100. This will be due to our investments in poverty alleviation, gender equity, education and health, ameliorating inequality, and food and energy security.

Archives (PRELIMS & MAINS Focus) Einstein’s theory of gravity Syllabus Prelims –Science and Technology Context: Recently, a new detailed map of dark matter has been found to be in agreement with Einstein’s theory of gravity. About Einstein’s theory of gravity:- Albert Einstein published his full theory of general relativity in 1915. As per this theory, no motion can exceed the speed of light. In general relativity (GR), concentrations of mass and energy curve the structure of spacetime, affecting the motion of anything passing near including light. Physicists made many exotic predictions using general relativity. Significance of the theory:- IMAGE SOURCE: Space – SciDump The theory explained the anomalous orbit of Mercury.  In 1919 when Arthur Eddington and his colleagues measured the influence of the Sun’s gravity on light from stars during a total solar eclipse. The bending of light around the Sun is small, but researchers realized the effect would be much larger for galaxies, to the point where gravity would form images of more distant objects. The phenomenon now called gravitational lensing.  The theory predicted the existence of black holes Black holes: objects with gravity so intense that nothing getting too close can escape again, not even light. General relativity showed that gravitation has a speed, which is the same as the speed of light. Catastrophic events like collisions between black holes or neutron stars produce gravitational waves. Researchers finally detected these waves in 2015 using the Laser Interferometer Gravitational Observatory (LIGO) Laser Interferometer Gravitational Observatory (LIGO): a sensitive laboratory that took decades to develop.

When the materials are magnetised in the same direction, the electrical resistance in the conductor is low. When the directions are opposite each other, the resistance increases. The magnetoresistance observed in the graphene-based device was found to be “almost 100 times higher than that observed in other known semimetals in this magnetic field range.” Uses:- It is used in hard disk drives and magnetoresistive RAM in computers, biosensors, automotive sensors, microelectromechanical systems, and medical imagers.

This is significant as the G7 nations account for a quarter of global carbon emissions. Key highlights of Carbon-Free Power By 2035:- Acceleration of renewable energy: The countries agreed to accelerate solar and wind energy investments to produce 1,000 gigawatts (GW) by 2030 from solar power and 150 GW of wind power from off-shore platforms. This move is in line with recent reports by the Intergovernmental Panel on Climate Change (IPCC) to ensure that global temperatures do not increase by more than 1.5°C of pre-industrial levels by the end of the century. Elimination of subsidies: The countries reaffirmed their commitment to the elimination of inefficient fossil fuel subsidies by 2025. Phasing out of inefficient fossil fuel subsidies is a key component of the Paris Agreement. Removal of government support towards fossil-fuel-driven power: The countries emphasized that, with the exception of a few clearly defined circumstances that are consistent with a 1.5°C warming limit and the goals of the Paris Agreement, they have stopped all new direct government support for unabated international thermal coal power generation by the end of 2021 and public support for the international unabated fossil fuel energy sector in 2022. The group will each provide an update on their approach to implementation by the end of 2023. The ministers have agreed to prioritize steps toward phasing out “unabated” coal power generation plants that do not employ mechanisms to capture emissions and prevent them from escaping into the atmosphere. The G7 countries have endorsed Japan’s national strategy that emphasizes clean coal, hydrogen, and nuclear energy to
