Background:- Researchers at ETH Zurich recently identified a previously unknown compartment in mammalian cells. They have named it the exclusome. About Exclusome:- It is present in mammalian cells made of rings of DNA. It is made up of DNA rings known as plasmids. It lies in the cell plasma. It is exceptional because eukaryotic cells (cells with nuclei) usually keep most of their DNA in the cell nucleus, where it is organized into chromosomes. The exclusome primarily comprises plasmids, which are circular DNA molecules. These can replicate independently of chromosomes. They are usually found in bacteria and other microscopic organisms. Some of these plasmids are derived from external sources, while others are called telomeric rings as they originate from the telomeres or capped ends of chromosomes. These plasmids lack the genetic instructions required for protein synthesis. This sets them apart from chromosomal DNA.

Indian Ocean Region:- A third of the world’s population (2.6 billion people) live in the region. 80% of global oil trade, 50% of the world’s containerized cargo and 33% of its bulk cargo passes through it. The region produces a combined total of $1 trillion in goods and services and intra-IORA trade is billed at around $800 billion. India’s other regional organizations, like SAARC (South Asian Association for Regional Cooperation) and BIMSTEC (Bay of Bengal Initiative for Multi-Sectoral Technical and Economic Cooperation), face their own challenges. While the QUAD (Quadrilateral Security Dialogue), has made progress, it remains U.S.-led, along with military allies Australia and Japan. China is actively trying to rope in India’s neighbours with groupings like the Belt and Road Initiative (BRI), China-Indian Ocean Region Forum on Development Cooperation, China-South Asian Countries Poverty Alleviation and Cooperative Development Centre, which exclude India. This makes IORA significant for India. About Indian Ocean Rim Association (IORA):- Establishment: 1997. Secretariat: Cyber City, Ebène, Mauritius.

Archives (PRELIMS & MAINS Focus) Air Quality Index (AQI) Syllabus Prelims –ENVIRONMENT AND ECOLOGY Context: Recently, Mumbai’s overall Air Quality Index (AQI) touched 191, which was worse than Delhi’s 84. Background:- The SAFAR app on Monday showed AQI levels in multiple pockets of Mumbai going down to the “poor” category, with most of these pockets being in the suburban belt of the city. About Air Quality Index (AQI):- IMAGE SOURCE: aqi. in Air Quality Index (AQI) is a number used by government agencies to measure air pollution levels and communicate it to the population. (Air pollution) There are six AQI categories, namely Good, Satisfactory, Moderately polluted, Poor, Very Poor, and Severe. Each of these categories is decided based on ambient concentration values of air pollutants and their likely health impacts (known as health breakpoints). AQ sub-index and health breakpoints are evolved for eight pollutants (PM10, PM2.5, NO2, SO2, CO, O3, NH3, and Pb) for which short-term (up to 24-hours) National Ambient Air Quality Standards are prescribed. As the AQI increases, it means that a large percentage of the population will experience severe adverse health effects. The measurement of the AQI requires an air monitor and an air pollutant concentration over a specified averaging period. The results are grouped into ranges. Each range is assigned a descriptor, a colour code and a standardized public health advisory. The pollution sources in India and in most Asian countries are numerous and incompletely understood. In Delhi, for example, it comes mostly from light and heavy-duty vehicle traffic emissions, road dust, solid fuel combustion for heating and cooking, biomass, waste burning, thermal power plants, diesel generators, construction and small-scale local industries. ( Delhi and Air Pollution) Government Initiatives:- The National Air Quality Index Standard (NAQI): It was launched by The Minister for Environment, Forests & Climate Change, Shri Prakash Javadekar, on 17 September 2014.

Background:- It is capable of running at speeds up to 180 km/hour which will eventually cut the journey time between Delhi and Meerut to less than an hour. About Regional Rapid Transit System (RRTS):- IMAGE SOURCE: THE INDIAN EXPRESS Launched: October, 2023. Constructed by: The National Capital Region Transport Corporation (NCRTC). NCRTC: It is a joint venture company of the Central government and the governments of Delhi, Haryana, Rajasthan and Uttar Pradesh. Ministry: Ministry of Housing and Urban Affairs. Objective: to ensure “balanced and sustainable urban development” through better connectivity and access across the NCR. It is a state-of-the-art regional mobility solution, comparable to the best in the world. Historical Background:- The idea of such a network lies in a study that the Indian Railways was commissioned to carry out in the year 1998-99. The study identified the possibility of an RRTS network to connect various locations in the NCR through fast commuter trains. The proposal was re-examined in the year 2006 with the extension of the Delhi Metro lines to some NCR towns such as Gurgaon, Noida and Ghaziabad. It was soon taken up by the National Capital Region Planning Board (NCRPB) while developing its “Functional Plan on Transport for NCR-2032”. Salient Features:- Rapid Transit System (RRTS) is also known as Namo Bharat. It is an integrated, mass transit network. The RRTS is modelled on systems such as the RER in Paris, Regional-Express trains in Germany and Austria as well as the SEPTA Regional Rail in the United States, among others. In line with PM GatiShakti’s National Master Plan, the RRTS network is to have extensive multi-modal integration with Railway stations, Metro stations, Bus services etc. Eight corridors will be developed under the project, of which three are being constructed under phase I: the 82-km Delhi-Ghaziabad-Meerut, the 164-km Delhi-Gurugram-SNB-Alwar, and the 103-km Delhi-Panipat corridors. The corridors to be developed in future include Delhi – Faridabad – Ballabgarh – Palwal; Ghaziabad – Khurja; Delhi – Bahadurgarh – Rohtak; Ghaziabad-Hapur; and Delhi-Shahadra-Baraut. Advantages:- The development of RRTS will boost economic activity. (National Rail Plan for Infrastructure Capacity Enhancement) It will provide improved access to employment, education & healthcare opportunities. It will help in the significant reduction of air pollution. The RRTS network is faster than the Metro. It will cater to commuters who want to travel relatively longer distances across the NCR in a short time. MUST READ: Rail Kaushal Vikas Yojana SOURCE: THE HINDU PREVIOUS

Key findings:- The treatment of malaria in eastern Africa is encountering a significant challenge as the parasites have started developing resistance to artemisinin, the core component used for treating the disease, according to a new study. Artemisinin-based combination therapy (ACT) has been a highly effective treatment for non-severe cases since the early 2000s. While the clinical effectiveness of ACT remains generally robust in the continent, the recent emergence of partial artemisinin resistance in the eastern African countries of Rwanda, Uganda and Eritrea has raised significant concerns. Most of the countries in Africa are not on track to achieving the goal of eliminating malaria in the continent by 2030, according to the African Union Malaria Progress Report 2022. About Malaria:- IMAGE SOURCE: A Happy Ending To Malaria Story? – Scientific Animations It is a life-threatening mosquito-borne blood disease. It is caused by Plasmodium parasites. It is predominantly found in the tropical and subtropical areas of Africa, South America as well and Asia. It is preventable as well as curable. Symptoms:- Symptoms usually begin ten to fifteen days after being bitten by an infected mosquito. Symptoms include fever, tiredness, vomiting, and headaches. In severe cases, it can cause jaundice, seizures, coma, or death. Transmission:- The parasites spread through the bites of infected female Anopheles mosquitoes. In the human body, parasites initially multiply in liver cells and then attack the Red Blood Cells (RBCs). There are 5 parasite species that cause Malaria in humans and 2 of these species (Plasmodium falciparum and Plasmodium vivax) pose the greatest threat. Prevention:- Using mosquito nets when sleeping in places where malaria is present Using mosquito repellents (containing DEET, IR3535 or Icaridin) after dusk Using coils and vaporizers. Wearing protective clothing. Using window screens. Treatment:- Artemisinin-based combination therapy medicines like artemether-lumefantrine are usually the most effective medicines. Chloroquine is recommended for the treatment of infection with the vivax parasite only in places where it is still sensitive to this medicine. Primaquine should be added to the main treatment to prevent relapses of infection with the P. vivax and P. ovale parasites. Most medicines used are in pill form. Some people may need to go to a health centre or hospital for injectable medicines. (Malaria Vaccine) India’s status:- In India, malaria elimination efforts were initiated in 2015. These were intensified after the launch of the National Framework for Malaria Elimination (NFME) in 2016. It is an initiative under the Ministry of Health and Family Welfare. NFME is in line with WHO’s 2016-2030 Malaria Strategy. (World Malaria Report 2021) WHO’s 2016-2030 Malaria Strategy: guides the WHO Global Malaria Programme (GMP).

About Hamoon:- IMAGE SOURCE: THE INDIAN EXPRESS Cyclone Hamoon is brewing near India over the Bay of Bengal. Southern states in India are likely to witness rainfall this week. According to the India Meteorological Department (IMD), a deep depression over the West central Bay of Bengal likely to intensify into a Cyclonic Storm during the next 6 hours.( Colour Coded Weather Warning) Cyclones Tej and Hamoon are considered to be twin cyclones that developed over the north Indian Ocean. The last such twin cyclones ‘Luban’ and ‘Titli’ were recorded in 2018. About Cyclone:- A cyclone is a pattern of winds (or air mass) that circulates a low-pressure system. It rotates counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere. It is typically associated with wet and stormy weather. (Naming of Cyclone) Classification:- There are two types of cyclones: Tropical cyclones and Extra-tropical cyclones (also called Temperate cyclones) Tropical cyclone:- It is an intense circular storm that originates over warm tropical oceans. It is characterized by low atmospheric pressure, high winds, and heavy rain. These are formed over slightly warm ocean waters. The temperature of the top layer of the sea, up to a depth of about 60 meters, needs to be at least 28°C to support the formation of a cyclone. April-May and October-December periods are conducive for cyclones. Then, the low level of air above the waters needs to have an ‘anticlockwise’ rotation (in the northern hemisphere; clockwise in the southern hemisphere). During these periods, there was an ITCZ in the Bay of Bengal. Extratropical cyclones:- It occurs in temperate zones and high-latitude regions, though they are known to originate in the Polar Regions. These are active above the mid-latitudinal region between 35° and 65° latitude in both hemispheres. The direction of movement is from west to east and is more pronounced in the winter seasons.

Archives (PRELIMS & MAINS Focus) Hunter’s Moon Lunar Eclipse Syllabus Prelims –SCIENCE AND TECHNOLOGY Context: Hunter’s Moon Lunar Eclipse is predicted to be seen on October 28th,2023. Background:- The “Hunter’s Moon” will officially be 100% illuminated at 3:35 p.m. EST on Saturday, October 28, 2023. About Hunter’s Moon Lunar Eclipse:- The Hunter’s Moon is one of the many names given to the full moons throughout the year. Each of these names have its own unique cultural and historical significance. Historical Significance:- Rooted in Native American, Colonial American, and other traditional North American cultures, the names of these moons were used to track the changing seasons and were adopted by colonial settlers. The Hunter’s Moon follows the Harvest Moon, which is the full moon closest to the autumnal equinox. Naming:- Historically, the Harvest Moon allowed farmers to work late into harvesting their crops by the moon’s light. Once the harvest was completed, the Hunter’s Moon would rise signaling a time when game would be fattened and hunted to store for the winter. This moon was a beacon for hunters to begin stocking up for the colder months ahead. Features:- The Hunter’s Moon can sometimes appear red or orange in color, due to the way that sunlight is scattered by the Earth’s atmosphere. This is especially common when the moon is low in the sky, such as during sunrise and sunset. This year’s Hunter’s Moon” will look both more colorful and larger than it will at any other time of night. It will only for about 15 minutes. It will also be more impactful because it’s being viewed in twilight, not darkness. Europe and Africa will be the best placed to see watch the entire event, but it’s a very slight partial lunar eclipse. At the peak of the event about 6% of the full moon will be inside Earth’s dark central shadow . It may look like a small bite has been taken from it. However, as it drifts through Earth’s lighter, outer penumbral shadow it will mostly just seem less bright than usual. About Lunar Eclipse:- An eclipse happens when a planet or a moon gets in the way of the sun’s light. (Eclipses ) A lunar eclipse occurs when the Sun, Earth, and Moon align so that the Moon passes into Earth’s shadow. In the Lunar Eclipse, the Earth arrives in between the sun and the moon. In this way, the shadow of the earth falls on the moon. The lunar eclipse can only happen during the Full Moon. But, the orbits of the moon and earth are different. That’s why the lunar eclipse happens only up to 3-4 times a year. There are three types of lunar eclipses: Total lunar eclipses, partial lunar eclipses, and penumbral lunar eclipses. Total lunar eclipse: entire Moon falls within the darkest part of Earth’s shadow, called the umbra. When the Moon is within the umbra, it will turn a reddish hue. Lunar eclipses are sometimes called “Blood Moons” because of this phenomenon. Partial lunar eclipse: An imperfect alignment of Sun, Earth and Moon results in the Moon passing through only part of Earth’s umbra. The shadow grows and then recedes without ever entirely covering the Moon. Penumbral eclipse: The Moon travels through Earth’s penumbra, or the faint outer part of its shadow. The Moon dims so slightly that it can be difficult to notice  MUST READ: Supermoon SOURCE: SCIENCE ALERT PREVIOUS YEAR QUESTIONS Q.1) In the northern hemisphere, the longest day of the year normally occurs on the: (2022) The first half of the month of June The second half of the month of June The first half of the month of July The second half of the month of July Q.2) On 21st June, the Sun (2019) does not set below the horizon at the Arctic Circle does not set below the horizon at Antarctic Circle shines vertically overhead at noon on the Equator shines vertically overhead at the Tropic of Capricorn World Development Information Day Syllabus Prelims –INTERNATIONAL RELATIONS Context: Recently, the United Nations (UN) celebrated the World Development Information Day.

About“Calixcoca” Vaccine:- Calixcoca’, is a therapeutic vaccine that promises to prevent the addictive effects of cocaine or crack.( Drug Addiction) It is offering new hope to millions battling cocaine addiction worldwide. (mRNA Vaccine) Working:- Calixcoca functions by inducing an immune response that generates antibodies capable of binding to cocaine molecules in the bloodstream. This binding process results in the enlargement of cocaine molecules, rendering them too large to pass into the brain’s “reward centre” or mesolimbic system. This area of the brain is typically stimulated by cocaine to release dopamine, the pleasure-inducing neurotransmitter. Consequently, individuals who receive the vaccine will not experience the desired euphoric effects of cocaine, potentially assisting them in breaking the cycle of addiction. Furthermore, it reduces the risk of overdose as cocaine molecules are retained in the blood, bound to the antibodies, and thus, unable to act on the heart or arteries. Following encouraging results in animal trials, Calixcoca is poised to enter the
