GENEVA, SWITZERLAND: When the world was shaken by Covul-19 which shredded economies. Overturned societies, crippled health systems, and killed millions of people-many countries came together and decided to build a framework of binding commitments to stop such such trauma from ever happening again. This happened in 2021

Since then, countries have been holding talks to make this happen but the talks have been caught in many issues. The final round of talks is happening this week, but countries are not even close to maching a deal that is acceptable to all parties.

World Health Organization [3:50 pm, 8/4/2024] IIFL: chief Tedros Adhanom Ghebreyesus has repeatedly warned nations that "everyone will have to give something, or no one will get anything."

 

Who wants what?

European countries - who led calls for a pandemic treaty want more money invested in pandemic prevention, while African nations want the knowledge and financing to make that work, plus proper access to pandemic "counter-measures" like vaccines and treatments.

The United States wants to ensure all countries share data and samples from emerging outbreaks quickly and transparently, while developing countries are holding out firm for guaranteed equity to stop them getting left behind.

According to the roadmap, a finalised accord on pandemic preparedness, prevention and response would be adopted at the May 27 to June 1 World Health Assembly of the WHO'S 194 member states

Issues at hand

The main topics still in play include access to emerging pathogens, better prevention and monitoring of disease outbreaks, reliable financing and transferring technology to poorer countries. The talks are being conducted by an Intergovemmental Negotiating Body.

The International Space Station (ISS) is a large spacecraft that orbitis around Earth every 90 minutes. It is not only a science laboratory but also serves as a home to crews of astronauts and Cosmonauts.

Its laboratory has components from the United States, Russia, Japan, and Europe.

The space station is used by National Aeronautics and Space Administration (NASA) scientists to learn more about living and working in space. The research here will make it possible to send humans farther into space than ever before.

History                                                                                               

Originally called 'Freedom' in the 1980s, then U.S. President Ronald Reagan authorised NASA to build the space station. It was redesigned in the 1990s to reduce costs and expand international involvement, at which time it was renamed.

In 1993, the U.S. and Russia agreed to merge their separate space station plans into a single facility and incorporate contributions from the European Space Agency (ESA) and Japan.

It took 10 years and more than 30 missions to assemble the space station. It was launched in 1998 with the help of the U.S., Russia, Canada, Japan, and the participating countries of the ESA. The first piece of the ISS was launched in November 1998. The ISS is the size of a large five-bedroom house or a football field and is able to support a crew of six people and some visitors

It is made up of several parts that were assembled in space by astronauts. The first crew reached the space station on November 2, 2000. People have lived on the space station ever since.

International Space Station

The space station is equal to a five-bedroom house or the size of a football field and is able to support a crew of six people, plus visitors. The laboratories in the space station help the crew members to do research that could not be done anywhere else.

At the ISS, the scientists also study what happens to the human body when people live in microgravity (place where there is almost no gravity) for a long time.

The space station has solar arrays, which collect energy from the sun to provide electrical power. The arrays are connected to the station with a long truss, which is a beam that is the backbone of the space station.

There are radiators on the truss that control the space station's temperature. Astronauts reach the space station on the Russian Soyuz spacecraft Operating the space station is more complicated than other space flight programmes as it is an international programme. Each partner is mainly responsible for managing and running the hardware it provides It is the largest space station ever constructed and yet it continues to be assembled in orbit.

Till now, it has been visited by astronauts from 18 countries During Prime Minister Narendra Modi's recent visit to the U.S.. President Joe Biden said that India and the US. will collaborate to send an Indian astronaut to the ISS in 2024.

Teaching is one of the noblest professions And a teacher is the biggest cheerleader of a shutent But teaching is also a thankless job. This Teachers Day lets read up on a few ways to make your teachers feel appreciated and values.

Celebrate Teachers Day

This may seem like the most obvious of all the things you ou do to make a teacher feel appreciated Indeed, how else to appreciate teachers than celebrating them? Teachers Day falls on September 5 So go ahead and make them feel special on this day You can write a note, make a cant make a speech, or even hold a small activity where you can share how your teacher has made an impact on your life. A heartfelt thank you will be sufficient for the teachers. Throwing such a surprise celebratory event is sure to make your teacher feel highly appreciated and valued. PHOTO R. RAGU/THE HINDU

Form study groups

Ever thought of helping out your peers? A teacher cannot always give attention to all the children in the class equally. Remember that theorem the maths teacher taught that you could quickly grasp but which turned out to be a tough nut to crack for most of the students? How about helping out the students and teaching them instead of waiting for the teacher to explain it again in the next class? You can easily form a study group and either use a free penod or vase the break to teach the students. If you are academically good, you can also form a study group to help the students who fair poorly in their academics. This will be beneficial for the students as well as the teacher and is one way to help your teacher. By teaching a concept you will also get thorough with it. This is because you have to fully understand something to be able to explain it to someone else. PHOTO: RAD GN

Say Thank You

We often undermine the power of a simple Thank You A heartfelt thank you is sometimes enough to warm the cockles of the heart of another person. So go ahead and say thank you to the teacher. You can share how much you appreciate them by either writing a letter, using a hand-drawn picture or just walking up to them and saying thank you Any small gesture will be appreciated by them. PHOTO: A.M. FARUQUI

Talk proudly about them Every individual needs praise. This helps them know that whatever they are doing is appreciated. While teachers may not necessarily need reassurance and validation, having chosen one of the thankless yet wholly satisfying professions themselves, it will definitely make a difference if you can make them feel appreciated. Talk about your teachers to your parents, friends, and even their parents. Praise their efforts and complement them wherever you can.

Volunteer

Everyone can use a little bit of help. And this includes teachers as well. Be ready to volunteer whenever some extra activity comes up in class. For instance, if there is an activity happening in the class where you can pitch in with your services, make sure you offer to volunteer. It may be as simple as rearranging the desks or washing the beakers in the lab or as taxing as helping with the organising of class programmes. In short, be helpful in class and the extra effort will definitely be appreciated by the teacher.

Be attentive in class

Nothing will make a teacher feel appreciated than a student who is highly attentive and responsive in class. Be a good student and always ask questions if you don't understand something.

Participating in class means that you are taking extra effort to focus on the topic being taught. Further, you will also have fewer chances of getting distracted or missing out on any topic on account of sitting farther from the chalkboard. Being attentive in class ensures that you understand concepts well and a teacher will surely feel appreciated seeing a class packed with students eager to learn.

Become a good, successful individual

 One of the most heart warming things for a teacher is to see their stulent coming out with flying colours not only during exams but in life as well. That's the biggest and loudest thank you any student can ever offer to a teacher. So go ahead, be attentive in class, do your best at academics. be good at extracurriculars, and become a goodl human being. Make sure you are consistent, and put in the time and effort to bring: your best self out at eams, extra-curricular, and even otherwise PHOTO ANI PHOTO/SANJAY SHARMA

Be up to date with homework and classwork

Students who finish their homework and assignments on time and who are always ready by bringing specific textbooks or workbooks to class is the dream of any teacher. If you finish all your homework on time, as stipulated by the teacher, not only does it benefit you by being academically up to date with what is being taught in the class but it ensures that you are prepared for the class and eventually, the exams. Further, it also helps the teacher as precious time gets wasted when children come unprepared for the classes. PHOTO: GETTY IMAGES/ISTOCKPHOTO

If you have followed the news. you must have often read about police making arrests on the basis of an FIR (First Information Report). However, do you know what FIR is?

What is an FIR?

An FIR is a written document prepared by the police in India. Pakistan and Bangladesh. Interestingly, it is not defined in the Indian Penal Code (IPC). Code of Criminal Procedure (CrPC), 1973, or in any other law, but is part of police regulations or rules.

An FIR is generally a complaint lodged with the police by the victim or by someone on his or her behalf about an offence. The informant is given a copy of the FIR free of cost.

After an FIR is filed, the police start investigating the case and can arrest the alleged persons as per law. If there is sufficient evidence to support the complaint, then a chargesheet is filed. Or else, a Final Report mentioning that no evidence was found is filed in court.

Filing an FIR

The procedure for filing an FIR is mentioned under Section 154 of the Criminal Procedure Code. 1973. Anyone can file an FIR either orally or in writing to the police.

People can also lodge an FIR online. Following the filing of an FIR, the police are bound to commence investigation into the case.

Here is the process to file an FIR: One has to visit the nearest police station and inform the police of all the details of the offence either verbally or in writing. If it is a verbal statement, the duty officer writes it down and makes an entry in the General Diary or Daily Diary. If it is a written complaint, one must carry two copies - one for the duty officer and the other for one's personal record.

The police will go through the details after submission of the complaint. Then the information recorded by the police is read over to the complainant.

Then one needs to sign the FIR after verifying that the information recorded by the police is as per the details given.

A free-of-cost copy of the FIR will be given to the complainant with an FIR number, date of FIR and the name of the police station. Both copies of the FIR are stamped bearing a Daily Diary number. It is a proof that the complaint has been received by the police.

These details can be used to access the FIR online for free if the copy is lost.

After an FIR is registered, its contents cannot be changed. However, additional information can be given to the police later on at any point

Zero FIR

The provision of Zero FIR was recommended for the first time in the report of the Justice Verma Committee. It was constituted to make amendments to the Criminal Law in order to speed up trial and enhance punishment for criminals accused of committing sexual assault against women.

The objective of a Zero FIR is to ensure the victim does not have to run to different police stations to get a complaint registered.

A person can even file a Zero FIR which means a police station can receive a complaint regarding an alleged offence that has been committed in the jurisdiction of another police station. The FIR can then be transferred to the concerned police station for further investigation.

If a person is refused by the officer in charge of a police station to register an FIR, he/she can send the complaint to the Superintendent of Police/DCP concerned.

Stars like our Sun radiate huge quantities of energy because of the nuclear fusion reaction taking place inside their core. Can we use the same idea to generate power that is clean and cheap? Where are scientists around the world working on such projects.

The energy scenario in the world is changing as natural sources conventionally used for generating energy like fossil fuels, oil and coal are fast depleting.

But there are abundant energy sources that cause minimal climate change. Nuclear energy is one such option being used worldwide. In this process, energy is released from the nucleus of an atom either by splitting the heavy atom into two (nuclear fission) or by combining two light atoms into a heavier one (nuclear fusion).

For more than 50 years, energy has been generated in nuclear power plants through fission, a process in which heavy elements such as uranium are bombarded by neutrons, resulting in the splitting of the nuclei and the release of huge amounts of energy in the form of heat.

Nuclear fusion is the opposite process. In fusion reactors, light atomic nuclei are compressed under intense pressure and heat, forcing them to combine together to form heavier nuclei. Fusion also results in the release of huge quantities of energy.

Special conditions Normally, atomic nuclei repel each other if we try to bring them closer; to force them to come close and ultimately fuse together, special conditions have to be generated in the form of very high pressure and extremely high temperatures.

Stars like our Sun radiate huge quantities of energy because of the nuclear fusion reaction taking place inside their core- hydrogen is continuously changing to helium.

The core experiences extremely high pressure because of the gravitational force exerted by the mass of the gigantic star itself, this pressure also leads to the generation of very high temperature inside the star. So, the basic requirement for a fusion reaction is to create a star-like situation inside the reactor in terms of temperature and pressure. To generate such conditions, a lot of energy is needed.

The process must be optimised to generate more energy than it consumes. Fusion could be utilised to generate electricity commercially. The main fuels used in nuclear fusion are deuterium and tritium, both heavy isotopes of hydrogen. Deuterium constitutes a tiny fraction of natural hydrogen, only 0.0153 per cent, and can be extracted inexpensively from seawater. The amount of deuterium present in one litre of water can in theory produce as much energy as the combustion of 300 litres of oil! This means that there is enough deuterium in the oceans to meet human energy needs for millions of years.

Building a fusion power plant that can withstand the immense temperature and pressures produced by this process is one of the century's greatest engineering challenges. The fuel must be heated to about 100 million degrees Celsius. At that hotter-than-the-sun temperature, a fully ionised gas-plasma is formed. The plasma will then be ignited to create fusion.

Like it or not, science and technology sees unprecedented growth during dire times. This is probably because funding flows into different branches of science like never before, allowing for progress inconceivable during ordinary times. Just like how the COVID-19 pandemic saw a global collective search for vaccines, there have been other times in the past - mostly during wars - when a number of scientific fields received a tremendous boost.

World War II was one such period when scientific progress was at its pinnacle. The ability to split an atom through nuclear fission was discovered in the 1930s. With its ability to release immense power realised, it wasn't long before the race to build a bomb with it was on. The Manhattan Project was born early in the 1940s and we all know what happened in Japan's Hiroshima and Nagasaki.

To retain influence                                           

While the Manhattan Project was led by the U.S., it was done in collaboration with the U.K. along with support from Canada. Following the war, however, the U.S. refused to share atomic information with the U.K. With the objective of avoiding complete dependence on the U.S., and to remain a great power and retain its influence, Britain sought to become a nuclear power.

The prospect was discussed in a secret cabinet committee in October 1946. While Chancellor of the Exchequer Hugh Dalton and President of the Board of Trade Stafford Cripps were opposed to the idea of a British bomb citing the huge costs involved, Secretary of State for Foreign Affairs Ernest Bevin had his way and work went ahead. By the time the bomb was ready, however, Winston Churchill's government came to power.

Penney at the helm

Led by British mathematician William Penney, who had worked on the world's first atomic bomb in the U.S., the project that went on to become Operation Hurricane began with a secret laboratory tasked with developing the trigger device. With the Soviets managing to successfully explode their first atomic bomb in 1949, Penney's team was under further pressure. Soon enough, the Brits were ready with their bomb.

Early in 1951, the Australian government agreed that the blast could take place at the uninhabited Monte Bello islands, an archipelago of over 100 islands lying off the coast of north-western Australia. The region was declared a prohibited zone and ships and aircraft were later warned to stay clear of an area of 23,500 nautical square miles off the coast.

Plym carries the bomb

 The troops were mobilised, the first set of vessels left for their destination in January 1952 and six months later HMS Plym, carrying the bomb, and the fleet flagship HMS Campania, made their way. The radioactive core, which used British and Canadian plutonium, was flown out later, and installed in the bomb on Plym very close to the scheduled detonation.

On the morning of October 3, 1952, Britain's first atomic bomb exploded, sending thousands of tonnes of rock, mud, and sea-water blasting into the air. The Plym was instantly vaporised, with scant bits of red-hot metal from the vessel falling on one of the islands even starting a fire.

An eye-witness account of a Reuters correspondent stationed less than 100 miles away mentions a grand flash followed by the appearance of a grey cloud-a zigzag Z-shaped cloud as opposed to the mushroom cloud that we instantly associate with such detonations.

The success of Operation Hurricane resulted in Penney being knighted. Churchill, who was serving as the Prime Minister of the U.K. for a second time, announced to the House of Commons that there had been no casualties and that everything had gone according to plan. While he did congratulate the Labour Party for their role in the whole project, he also did take a dig at them saying that 'as an old parliamentarian I was rather astonished that something well over £100 million could be disbursed without Parliament being made aware of it.'

Over 2 billion radio receivers and over 20,000 radio stations exist worldwide. There is no truth about the notion that radio will be replaced by TV or other modern communication technologies, as it continues to expand Being the most economical electronic medium to broadcast and receive in, it breaks down barriers of illiteracy and isolation, making it the preferred electronic medium of the underprivileged. In radio broadcasting, community radio is a significant third tier that is different from commercial and public service radio.

What is a Community Radio?

 

Community Radio Stations (CRSs) are low-power radio stations designed for local communities to own and run. Local perspectives on topics related to health, nutrition, education, agriculture, and other topics are provided in a forum by Community Radio. People may immediately relate to the Community Radio broadcast because it is in their native language. A source of regional folk music and cultural legacy, the radio is especially important in a country like India where each state has its own language and unique cultural flavour. Community radio stations have grown significantly in popularity and number in the last 20 years. The social and economic advantages that arise from providing regular people with access to relevant information are now becoming more widely recognized.

The history of community radio

It was in Latin America, around 50 years ago, that the groundbreaking experiences that have given rise to community radio. The initial experiences-known the Miners' Radios in Bolivia in 1947 and Radio as Sutatenza in Colombia that same year were sparked by poverty and social injustice. Community radio emerged as a significant phenomenon in Europe, serving as an opponent or substitute for mainstream broadcast media, despite the breakthrough work being done in Latin America. Following the fall of the colonial government in South Africa, community radio stations across the continent were established and eventually evolved into a social movement.

The Indian government published the first set of community radio guidelines and the necessary equipment in early 2003, but limited the eligibility to educational institutions alone. The goal of establishing community radio stations that would involve local communities in the content production process has just recently expanded to include non-profit organizations, agricultural research institutes, and educational institutions.

Imagine a forest underwater or a tapestry of green inside the ocean. That's just what a kelp forest is. Though kelps are considered the forests of the sea and look like plants, they are not plants. Kelps are large brown algae, and together, the different species of kelps form kelp forests.

The kelp forests figure among one of the most dynamic and diverse ecosystems on earth and offer a habitat for marine organisms such as invertebrates, fishes, and other algae and play many key ecological roles.

Kelps cover 25% of the world's coastlines. They provide food and shelter to marine animals. These can be seen around the world, across polar as well as temperate coastal oceans. They live in cold waters that are rich in nutrients.

While they remain attached to the seafloor, they grow towards the surface of the water and depend on sunlight to generate food. The ideal physical conditions are satisfied, then kelps can grow 45 cm a day. Some of these species are seen to measure up to even 45 m long.

Kelps and climate change

Kelp forests play a highly crucial role in battling climate change as they are good at sequestering carbon, thereby ensuring the health of the coastal environment. They are also capable of absorbing excess nitrogen and phosphorus that nun into the oceans from the land. Studies have shown that a third of the globe's coastal environments depend on kelp to combat local pollution and sustain fisheries. Apart from helping maintain the health of the marine ecosystem, kelps are also commercially harvested as they find applications in food production, textiles, pharmaceuticals, and so on.

The health of the kelps is dependent largely on oceanographic conditions and as such they can disappear and reappear based on this. For instance, sea urchins can destroy the kelp forests. Moreover, strong individual storms can affect the kelp forests by tearing out the kelps from the floor of the sea.

These dense canopies of algae are also facing many threats. Water pollution, rising sea temperatures, overgrazing, overfishing, and water pollution are some of the reasons for the depletion of kelp forests.

Studies prove that Southern Australia and Northern Califonia have lost 95% of their kelp forests. Their depletion is seen along the coastlines of every continent and this affects the fish, livelihoods and economy that are supported by the kelp forests.

A large portion of our planet's land surface is covered by forests (of different types). These include tropical, subtropical temperate, and boreal forests. While forests the world over are threatened by global warming boreal forests grapple additionally with an issue unique to them. What is it? Come; let's find out the boreal forests of the northern hemisphere span Scandinavia, Siberia, Alaska, and Canada. Due to this vastness and the sheer number of trees they hold, these forests are an important carbon sink. Carbon has also accumulated over thousands of years in the soil due to the (long) time it takes for dead organic matter to decompose, thanks to the region's cold climate and water-logged ground. The ecosystems here have been shaped mainly by "wildfires ignited by lightning" During these fires, due to the quantum of carbon it holds, a boreal forest "will release 10 to 20 times more carbon compared to a similarly sized fire in other ecosystems". But then, unlike most other types of forests, these forests "might burn only once a century, sometimes even less often than that". Because of this frequency, the amount of carbon stored has always exceeded that of carbon released into the atmosphere; it has been so for at least 6,000 years now. But now global warming is threatening this delicate balance.

Due to rising global temperatures, the fire season has become longer, leading to an increase in the frequency and severity of wildfires. As the "interval between fires shortens, more carbon is being released from organic soils in boreal forests than the ecosystems can reabsorb". A new study shows a dramatic spike "in emissions from boreal fires over the past two decades". In 2021 alone, they showed "a record 23% of global vegetation wildfire emissions, more than twice their contribution in a more typical year. If such spikes continue, it is likely that boreal forests may soon become a significant source of global emissions from biomass burning.

Did you know that some famous literary classics almost ended in a completely different way? If you are fine with spoilers, read on...

Great Expectations

Great Expectations by English novelist Charles Dickens follows the life of Pip, a young orphan who dreams of transcending his humble origins and becoming a gentleman. Through a mysterious benefactor, Pip is granted financial resources, thus fulfilling his aspirations. However, his newfound wealth and status lead him down a path of self-discovery, where he encounters various characters who shape his journey.

Dickens initially penned a bleak conclusion for this masterpiece. However, prior to its publication in 1861, a group of his trusted friends intervened, urging him to reconsider the ending. They proposed a revision that would introduce a glimmer of hope, a chance for the protagonist Pip and his beloved Estella to mend their broken relationship. Although Dickens approached this alteration with a hint of reluctance, he ultimately embraced the suggestion and made the change.

A Farewell to Arms

 A Farewell to Arms by American novelist Ernest Hemingway is a novel that was published in 1929. This classic follows the story of an American ambulance driver named Frederic Henry, who serves in the Italian army during World War 1. The book explores important themes such as love, war, and the feeling of disappointment that comes from witnessing the horrors of battle. Hemingway's portrayal of how people respond to tragedy makes this book a significant and enduring piece of literature. Interestingly, Hemingway went through extensive revisions to find the perfect ending for the book. In 1958, he mentioned in an interview that he rewrote the ending 39 times until he was satisfied. However, in a 2012 edition of the book, his grandson Sean Hemingway, shared that he discovered an astonishing 47 different alternative endings to the book hidden within his grandfather's papers.

Rinkitink in Oz

Rinkitink in Oz is a delightful children's fantasy novel written by American author L. Frank Baum and published in 1916. It is part of the famous Oz series, which includes the beloved classic The Wonderful Wizard of Oz It follows the jolly character Rinkitink from the kingdom of Gilgad, who unexpectedly ventures into the magical Land of Oz with Prince Inga and a talking goat named Bilbil Baum wrote 14 Oz books in his lifetime. However, Rinkitink in Oz the 10th book in the Oz series. stands out as a unique entry. Although it is widely regarded as an excellent story, around 90% of the tale unfolds outside of Oz. Only at the very end does Dorothy make a sudden appearance to introduce the heroes to the wonders of Oz The reason for this divergence is quite straightforward the book was originally written as a standalone fairy tale with no connection to the Oz universe, a decade before its inclusion in the series. When in need of a new Oz book and feeling weary after a busy period of writing. L. Frank Baum repurposed Rinkitink's story and reworked its ending to integrate it into the popular series. The great news is that despite its deviation from the typical Oz setting. Rinkitink in Oz is considered one of the finest stories in the entire series.

Persuasion

Persuasion is English novelist June Austen's final completed novel, written after Emma and finished in August 1816, a year before her death at the age of 41 The stony follows Anne Elliot, who is persuaded by her family to decline a marriage proposal from Captain Frederick Wentworth, Years later, circumstances reunite them, compelling Anne to confront her emotions and societal expectations Interestingly, the published ending of the book was not Austen's original one. In James Edward Austen-Lengths A Memoir of Jane Austen, the authors nephew included the "cancelled chapters associated with the book, revealing Austen's first ending of the novel. However, she became dissatisfied with it and rewrote the chapters between July and August 1816. These unique pages are the only surviving manuscript of a novel Austen planned and completed for publication The revised ending, was published in the first edition of the novel in 1818. Since the release of A Memoir of Jane Austen in 1871, both readers and critics have agreed that Austen made the right choice by selecting the altemate ending. It is widely regarded as superior for it offered a greater emotional depth and artistry.

Is there a “right age” to learn a new language? When are we most receptive to learning a language? How do children learn languages? What are the benefits of picking up a foreign language? Let's find out...

How do children learn language?

One researcher called Noam Chomsky believed that the ability to team language is innate. Every child instinctively knows how to combine nouns and verbs to form the structure of sentences, and he will learn to do so regardless of whether he is taught to do so. The researcher had observed that children all over the world, no matter what language they speak, acquire language at around the same ages-they will learn their first words at the same time, speak bwo-word phrases at the same time and start speaking in sentences at the same age

Another researcher B. F. Skinner disagreed. He believed that children learn language through experience and rewards and punishment. For instance, if there is a dog in the room and the child says 'dog, his mother will reward him with a smile. The child thus learns that dog is the correct term for the creature and will use it the next time. Similarly, teachers and parents will criticise incorrect grammatical constructions and reward correct ones, and that is how the child learns to speak correctly.

Is there a right age to learn a language? One can learn to speak a language at any time. However, there seems to be a 'critical period for language development-about age 5, when we are most receptive to learning a language. It is easier to pick up a language at this age.

Learning foreign languages

Research has demonstrated many benefits of learning a foreign language. Apart from the obvious benefits of learning about a new culture and being able to communicate better with people from different countries, it also helps to develop several mental skills. When you learn a new language, you tend to pay more attention to grammar rules and sentence construction, and through this, you get a better understanding of the structure of language. Ultimately, this helps you to use your original language more effectively. Learning French will thus make you a better English speaker as well. Individuals who speak more than one language have been found to have better attention spans. They may be better at multi-tasking and decision making.

Learning a language can also boost our memory. Some researchers have found that learning a new language helps to enhance the development of certain areas of the brain-you actually build grey matter, just as exercising helps to build muscles! Bilinguals, i.e., people who can speak two languages, have been found to develop Alzheimer's disease (a disorder in old age where people lose their memory) at a much later age than those who speak just one language.

Quick tips

We can use psychological principles to help us leam a foreign language. Here are some tips.

• Language is best learnt in the natural surroundings where it is spoken, rather than in a classroom. Hence, speaking to others who speak the language and leaming conversational phrases, is more effective than mere rote repetition of words and grammatical structures.
• Exposure is key-it is useful to immerse yourself in the language, rather than devote one hour per day to studying the language. The reason why people who go to a foreign country learn to speak the language quickly is that they are surrounded by it. Watching movies, listening to songs, reading books and talking to people in the language will be of great help. You can also keep little vocabulary chits around your house write a cand saying the French word for mirror and place it next to the mirror, the word for ‘toothbnish' near the toothbrush, etc.
• Working on all aspects of the language speaking, listening, reading and writing is helpful to understand how a word is written and pronounced.
•  Practise-One of the best ways to learn a language is to keep speaking it, rather than passively listening. Do not worry about making mistakes. Talking to native speakers of that language, forming a study group where all of you converse in that language completely, is very effective. Online groups are also available.
• Have fun with it-Having fun with learning helps to keep you motivated. Singing songs, playing word games, enacting plays in the language, etc. will help you learn it better.

The Japanese call it 'Sakura Matsuri' It is a festival held in spring every year all over Japan and also in a number of other countries. It celebrates the blooming of the cherry trees and is a time for locals to have a picnic or hanami and enjoy the pleasant weather outdoors. There are blossom-viewing parties held both in the cities and the countryside.

The tree that is so revered is the Yoshino cherry tree or sakura that puts out exquisite pale pink blossoms. The cherry blossom is Japan's national flower. It is grown for its ornamental beauty and does not bear fruit.

Short but colourful life

To the Japanese, cherry blossom symbolises the ephemeral or transient quality of life. It features prominently in Japanese art, literature and folklore. At the picnics and parties, guests compose short poems or create brush paintings on the spot in celebration.

Cherry blossom festivals are a Occasion for street fairs, with stalls selling local craft and food. Visitors can also relish traditional theatre and dance performances.

The arrival of the cherry blossom is tracked closely with round-the-clock - news reports providing updates on exactly where and when the fabled flowers will appear. The blossoming begins in January in Okinawa and reaches Kyoto and Tokyo in April. It blooms last in Hokkaido in the northern reaches a few weeks later. The flower was used to whip up patriotic fervour during World War Il with the soldiers' sacrifice compared to the falling of the blossoms. Japanese pilots on suicide missions painted the cherry blossom on the side of their planes.

Blooming friendship

Japan has gifted thousands of cherry trees as a goodwill gesture to several countries. The cities which have nurtured these cherry orchards hold a cherry blossom festival every spring, just like in Japan. One such city is Washington D.C. which received 3,000 trees from Japan in 1912.

Every spring, the Tidal Basin along the Potomac River in Washington DC erupts in a shower of white and pink as thousands of cherry blossom trees bloom in all their glory.

Even the ancient Romans liked their pizza Archaeologists in Pompeii said Tuesday they had found depicted on an ancient fresco the precursor to the modern-day pizza-but without the cheese and tomatoes.

The 2,000-year-old painting- discovered in the middle of a half-crumbled wall during recent digs at the sprawling archaeological site - depicts a silver platter holding a round flatbread, alongside fresh and dried fruits such as pomegranates and dates and a goblet filled with red wine.

What was depicted on the wall of an ancient Pompeian house could be a distant ancestor of the modern dish," said experts at the archaeological park in a statement.

Pompeii's director, Gabriel Zuchtriegel, said the newly uncovered fresco shows the contrast between "a frugal and simple meal, which refers to a sphere between the bucolic and the sacred... and the luxury of silver trays and the refinement of artistic and literary representations."

How can we fail to think, in this regard, of pizza, also born as a 'poor dish in southern Italy, which has now conquered the world and is also served in starred restaurants," Zuchtriegel added. AFP

POMPEII'S PAST

• A devastating volcanic eruption of Mount Vesuvius in AD 79 buried the Roman city in thick ash, hiding from view its many treasures that archaeologists continue to slowly bring to light.
• Archaeologists estimate that 15 to 20 percent of Pompeii's population died in the eruption, mostly from thermal shock as a giant cloud of gases and ash covered the city.

WHAT THE EXCAVATION REVEALS...

• The fresco is believed to refer to the "hospitable gifts" offered to guests, following a Greek tradition dating to the 3rd to 1st centuries BC and described by imperial Roman-era writers including Virgil and Philostratus.
• It reveals an atrium of a house that included an annex with a bakery.
• In the working areas near the oven, the skeletons of three victims have been found in the past weeks.

India's aspirations in the outer space and acceptance of the Artemis Accords have affirmed the country's interest in building a greater relationship with the National Aeronautics and Space Administration (NASA) and its partners. As the space community lauds India's acceptance of the Artemis Accords, let us know more about it.

Artemis Accords

The Artemis Accords are part of the Artemis programme, which is a mega-initiative by NASA with the aim to land the first woman and first person of colour on the Moon, make new scientific discoveries, and explore more of the lunar surface. Artemis is the name of the goddess of the Moon in Greek mythology and also the twin sister of Apollo.

The Artemis Accords were established in 2020 by NASA, the U.S., and seven other founding member nations - Australia, Canada, Italy, Japan, Luxembourg, UAE, and the U.K. This June 21, India became the 27th country to sign the Artemis Accords.

The Artemis Accords are a set of non-binding guidelines designed to guide civil space exploration and use in the 21st Century. It is a NASA-led effort to return humans to the moon by 2025, with the ultimate goal of expanding space exploration to Mars and beyond.

The Artemis Accords reinforce and implement key obligations in the 1967 Outer Space Treaty (which provided the basic framework for international space law). The accords also affirm the importance of the Rescue and Return Agreement opened in 1968, which emphasises the responsibility of nations to safely return astronauts and equipment to Earth.

Besides, the accords emphasise the need to preserve historically significant human or robotics landing sites, artefacts, spacecraft, and other evidence of activity on celestial bodies.

Outer Space Treaty

The Outer Space Treaty is an international treaty binding the parties to use outer space only for peaceful purposes. The treaty was enforced on October 10, 1967, after being ratified by the U.S., then Soviet Union, the U.K.. and several other countries.

The treaty prohibits countries from placing nuclear arms or other weapons of mass destruction in orbit, on the Moon, or on other bodies in space. Also, no country can claim sovereignty over the Moon or other celestial bodies. The countries are liable for any damage caused by objects launched into space from their territory.

India and the Artemis Accords

India's Indian Space Research Organisation (ISRO) and NASA had been working together in several lunar missions. However, the cooperation was limited to sharing knowledge. With the signing of the Accords, India and the US will share data, technology, and resources, and work together in ensuring the safety and sustainability of exploring the Moon.
