What are the meaning, origin and usage of word ‘Revitalize’?

(pronounced as ri,vai,tal,aiz)

Meaning: The word revitalize corresponds to imbuing something with new life and vitality.

Origin: The word, which has been around since the 1840s, is arrived at by combining re with vitalize. While the re denotes "back, again", the vitalize is used to imply "giving life to". The word vitalize has been around since the 1670s and is arrived at by giving vital the suffix ize.

The word grew steadily in popularity in the second half of the 20th Century and reached a peak around the turn of the century. While its usage has come down since then, it still enjoys considerable popularity.

Usage: Her introduction as a substitute revitalised the entire team to perform better.

What is zika virus?

 A five-year-old girl in Karnataka recently tested positive for Zika virus.

Mosquitoes are notorious for their itchy bites, but what makes them a cause for concern is their ability to carry and spread deadly diseases to humans. Diseases spread by mosquitoes include Zika fever, chikungunya, Japanese encephalitis, dengue, and malaria. Recently, a five-year-old girl in Karnataka tested positive for zika virus, a mosquito-borne disease.

 The Zika virus is transmitted by the Aedes species of mosquito. It is transmitted by Aedes aegypti, which bites during the day and is generally found throughout the world.

Though the infection is not serious for most people, it can be dangerous for pregnant women. The infection during pregnancy can cause infants to be born with microcephaly, a condition where a baby's head is much smaller than expected restricting brain growth. Aedes mosquitoes can be distinguished by their narrow, black body, and alternating light and dark bands on the legs.

What we need to do is to be aware of the symptoms of Zika fever and keep ourselves safe. The symptoms of Zika virus are fever, rash, conjunctivitis, muscle and joint ache, and headache that last about a week.

Avoiding mosquito bites in places where the Zika virus has been reported is a way of preventing the disease. Stay fully covered in the mornings and sleep under a mosquito net during the night if your area is mosquito-prone. Aedes aegypti mosquitoes breed in clean water. So removing stagnant water helps. Keep your clean to prevent mosquitoes from breeding.

What does a dust devil sound like on Mars?

Mars rover’s microphone captures ten seconds of rumbling noise created by dust devil on the Red Planet. It's the same microphone that provided the first sounds of Martian wind in 2021.

What does a dust devil sound like on Mars? A NASA rover by chance had its microphone on when a whirling tower of red dust passed directly overhead, recording the racket.

It's about 10 seconds of not only rumbling gusts of up to 40 kph, but the pinging of hundreds of dust particles against the rover Perseverance. Scientists released the first-of-its-kind audio. It sounds strikingly similar to dust devils on Earth, although quieter since Mars' thin atmosphere makes for more muted sounds and less forceful wind, according to the researchers.

The dust devil came and went over Perseverance quickly last year, thus the short length of the audio, said the University of Toulouse's Naomi Murdoch, lead author of the study appearing in Nature Communications.

At the same time, the navigation camera on the parked rover captured images, while its weather-monitoring instrument collected data.

"It was fully caught red-handed by Persy," said co-author German Martinez of the Lunar and Planetary Institute in Houston.

Photographed for decades at Mars but never heard until now, dust devils are common at the red planet.

This one was in the average range: at least 400 feet (118 metres) tall and 80 feet (25 metres) across, travelling at 16 feet (5 metres) per second.

The microphone picked up 308 dust pings as the dust devil whipped by, said Murdoch, who helped build it.

Given that the rover's SuperCam microphone is turned on for less than three minutes every few days, Murdoch said it was "definitely luck" that the dust devil appeared when it did on Sept. 27, 2021. She estimates there was just a 1-in-200 chance of capturing dust-devil audio. Of the 84 minutes collected in its first year, there's "only one dust devil recording," she wrote in an email from France.

WHAT IS A DUST DEVIL?

  • Common across Mars, dust devils are short-lived whirlwinds loaded with dust that form when there is a major difference between ground and air temperatures.
  • They are a common feature in the Jezero crater, where the Perseverance rover has been operational since February 2021 - but it had never before managed to record audio of one of them.
  • By chance on September 27, 2021, a dust devil 118 metres high and 25 metres wide passed directly over the rover.
  • This time, the microphone on the rover's SuperCam managed to catch the muffled, whirring sounds.

Sounds...so far

  • The same microphone on Perseverance's mast provided the first sounds from Mars namely the Martian wind soon after the rover landed in February 2021.
  • It followed up with audio of the rover driving around and its companion helicopter, little Ingenuity, flying nearby, as well as the crackle of the rover's rock-zapping lasers, the main reason for the microphone.

ROCK SAMPLES

On the prowl for rocks that might contain signs of ancient microbial life, Perseverance has collected 18 samples so far at Jezero Crater, once the scene of a river delta. NASA plans to return these samples to Earth a decade from now. Its helicopter Ingenuity has logged 36 flights, the longest lasting almost three minutes.

CAN ACOUSTIC DATA SOLVE THE MARTIAN MYSTERY?

  • These recordings allow scientists to study the Martian wind, atmospheric turbulence and now dust movement as never before.
  • The impact of the dust-made "tac tac tac sounds will let researchers count the number of particles to study the whirlwind's structure and behaviour.
  • It could also help solve a mystery that has puzzled scientists. On some parts of Mars, whirlwinds pass by sucking up dust, cleaning the solar panels of rovers along the way.
  • Understanding why this happens could help scientists build a model to predict where the whirlwinds might strike next.
  • It could even shed light on the great dust storms that sweep across the planet, famously depicted in the 2015 science-fiction film "The Martian".

What is the explanation of nuclear fusion?

Researchers have surpassed an important milestone for nuclear fusion technology: getting more energy out than was put in. Some consider this to be the energy of the future since nuclear fusion produces no greenhouse gases and leaves little waste. So, how does it work, what projects are underway, and when could they be completed? Come, let's find out

What is fusion?

Fusion is the process that powers the sun. Two light hydrogen atoms, when they collide at very high speeds, fuse together into one heavier element, helium, releasing energy in the process. (Fusion differs from fission, the technique currently used in nuclear power plants, by fusing two atomic nuclei instead of splitting one.) "Controlling the power source of the stars is the greatest technological challenge humanity has ever undertaken," tweeted physicist Arthur Turrell, author of "The Star Builders".

Creating fusion on Earth

Producing fusion reactions on Earth is possible only by heating matter to extremely high temperatures - over 100 million degrees Celsius. "So we have to find ways to isolate this extremely hot matter from anything that could cool it down. This is the problem of containment." Erik Lefebvre, project leader at the French Atomic Energy Commission (CEA), said.

One method is to "confine" the fusion reaction with magnets. In a huge doughnut shaped reactor, light hydrogen isotopes (deuterium and tritium) are heated until they reach the state of plasma, a very Low density gas. Magnets confine the swirling plasma gas, preventing it from coming into contact with the chambers walls, while the atoms collide and begin fusing. This is the type of reactor used in the major international project known as ITER currently under construction in France, as well as the Joint European Torus (JET) near Oxford, England.

A second method is inertial confinement fusion, in which high energy lasers are directed simultaneously into a thimble-sized cylinder containing the hydrogen (as shown in the graphic). This is the technique used by scientists at the National Ignition Facility (NIF) at Lawrence Livermore National Laboratory (LLNL) in California, the U.S. who were behind the recent announcement. Inertial confinement is used to demonstrate the physical principles of fusion, while magnetic confinement seeks to mimic future industrial-scale reactors.

What is net energy gain?

For decades, scientists had attempted to achieve what is known as "net energy gain" - in which more energy is produced by the fusion reaction than it takes to activate it.

LLNL director Kim Budil cautioned that much remains to be done before this energy can be commercially viable. "There are very significant hurdles, not just in the science but in technology," Budil said. "A few decades of research on the underlying technologies could put us in a position to build a power plant." To get there, researchers must first increase the efficiency of the lasers and reproduce the experiment more frequently.

Fusion has several benefits, but...

The NIF's success has sparked great excitement in the scientific community, which is hoping the technology could be a game-changer for global energy production.

Unlike fission, fusion carries no risk of nuclear accidents.

"If a few lasers are missing and they don't go off at the right time, or if the confinement of the plasma by the magnetic field... is not perfect," the reaction will simply stop, Lefebvre says.

Nuclear fusion also produces much less radioactive waste than current power plants, and above all, emits no greenhouse gases. "It is an energy source that is totally carbon-free, generates very little waste, and is intrinsically extremely safe," according to Lefebvre, who says fusion could be "a future solution for the world's energy problems".

However, the technology is still a far way off from producing energy on an industrial scale, and cannot therefore be relied on as an immediate solution to the climate crisis.

2022 up-close: species in the news

While the arrival of cheetahs from South Africa certainly dominated headlines in 2022, several other species too were in the spotlight in our country for various reasons. Let's take a look at a few of them

Tiger

As a keystone species, the tiger continues to get national attention, and rightly so. Our country is home to over 50 tiger reserves, and this year, two more got added to that list. The 52nd tiger reserve is in Rajasthan-Ramgarh Vishdhari, spread across Bundi, Bhilwara, and Kota districts over an area of more than 1,500 sq.km. The State's fourth tiger reserve - after Ranthambore, Sariska, and Mukundra, it is expected to be a major corridor connecting tigers of Ranthambore and Mukundra reserves. The country's 53rd tiger reserve is in Uttar Pradesh-the Ranipur Tiger Reserve in Chitrakoot district, spread over nearly 530 sq.km. This is the State's fourth tiger reserve after Dudhwa, Pilibhit, and Amangarh. The new reserve in the Bundelkhand region is just 150 km from the Panna Tiger Reserve in Madhya Pradesh.

Elephant

While Project Tiger is perhaps the most popular in the country, there are other projects looking at protecting specific species. One of them is Project Elephant. Set up in 1992, the initiative has been pivotal in the creation of several elephant reserves across the country. In October, the newest addition to the list - Terai Elephant Reserve at Dudhwa-Pilibhit in Uttar Pradesh - was approved by the Union government. When it becomes a reality, it will be the country's 33rd elephant reserve, and according the government, "will help in conserving trans-boundary migratory elephant population".

Dugong

The year 2022 is seen as a watershed moment in the conservation of a vulnerable marine species-the dugong. Tamil Nadu notified India's first ever dugong conservation reserve in the Palk Bay area of the Gulf of Mannar, which lies between Sri Lanka and the southern tip of India. The move, though seen as long overdue, is vital for the animal as much as it is for the local communities. Keeping with dismal global records, India's dugong population too has been declining. It is believed that there could be just around 200 dugongs left in our waters. These marine mammals, also called sea cows, can be spotted in our country near the Andaman and Nicobar Islands and off the coast of Tamil Nadu in the Gulf of Mannar and Palk Bay. It's in the Palk Bay, on approximately a 450-sq km. area, that the reserve will come up.

Turtles

It's not just large creatures that were in the news in 2022. Even smaller ones such as tortoises and turtles got global attention. To be precise, at the 19th Meeting of the Conference of the Parties (CoP 19) to the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) held at Panama City in November. According to the Union government. "At CoP 19, India's proposal for induction of fresh water turtle Batagur kachuga eamed wide support of the parties in CoP 19 of CITES It is said that CITES also recorded the works done "in the area of conservation of tortoises and fresh water turtles and efforts made in combating wildlife crime and illegal trade of turtles in the country" At the event, India "reiterated its commitment regarding conserving tortoises and fresh water turtles in the country"

Great Indian bustard

The one bird species that's often in the news in our country is the great Indian bustard. It was no different in 2022. Though the news about the bird is often worrisome, this time around it appeared to offer some hope for the species, and consequentially, conservationists. One of the reasons for the bird's fatality is through overhead power lines hit. The Supreme Court had initiated many steps to protect the species, including setting up a three-member committee to assess the feasibility of laying high-voltage underground power cables in Rajathan and Gujarat, States where the birds are sighted today. In such a scenario, late in 2022, the country's top court asked the union government why it should not consider the idea of establishing Project Great Indian Bustard on the lines of the country's successful Project Tiger.

What is Kuiper Belt?

Also called the "third zone" of the solar system, this large volume of space outside Neptune's orbit is home to thousands of icy, cold objects. This is where Pluto is also present.

In the cold, outermost area of our solar system lies one of the largest structures in our solar system. Also called the "third zone" of the solar system, this "donut-shaped" volume of space is called the Kuiper belt. This is where Pluto is also present.

The region encompasses hundreds of thousands of icy, cold objects and is outside Neptune's orbit.

The region is named so after astronomer Gerard Kuiper, who published a paper speculating objects beyond Pluto. This was also suggested by Astronomer Kenneth Edgeworth in the papers he published and sometimes this belt is called the Edgeworth-Kuiper Belt. Some researchers also refers to it as the Trans-Neptunian Region.

The icy bodies are called Kuiper Belt Objects (KBOS) or trans-Neptunian objects (TNOS). They are highly diverse in terms of size, shape, and colour. A significant number of KBOS have moons.

So how did the icy objects form? According to scientists, these icy objects are leftovers after the formation of our solar system. The region must have formed after these objects came together to form a planet but Neptune's gravity played spoilsport. The gravity shook up this region and these icy objects couldn't join to form a planet.

The Kuiper Belt volume is being lost nowadays. The amount of material which it carries now is much less when compared to what it contained earlier.

The objects in the belt collide and lead to fragmented, smaller objects. Sometimes the dust gets blown out of the solar system. We take a look at a few of the KBOS.

Haumea

This KBO is known for its strange shape and rotation style. According to NASA, the Haumea resembles a squashed American football. This was a result of the object's collision with another object half the size of it.

Eris

Smaller than Pluto, Eris takes 557 years to orbit the Sun. It has a moon called Dysnomia.

Arrokoth

Lying some billion miles past Pluto is the Arrokoth, a Kuiper Belt Object which means sky in the Native American language. This small snowman-shaped object is believed to hold clues about the origin of life on Earth and also about the planet's formation.

Who is the best-selling author of all time?

Agatha Christie is famed as the best-selling author of all time, However, she was not the most prolific writer of her family. Agatha grew up with two older siblings, out of them, her older sister Margaret (nicknamed Madge) also pursued writing and was considered to be the more promising writer.

By 1916, Madge had already written and published a few short stories, while Agatha had not published any. So when the latter shared the idea of writing a mystery novel with Madge, her sister was not as enthusiastic. She bet that Agatha would not be able to craft a compelling mystery and it certainly would not be something she could not solve. Taking up the challenge, the 26-year-old Agatha got to work and wrote, what would become her debut mystery novel, The Mysterious Affair at Styles. Today, this novel stands alongside hundreds of mysteries Agatha crafted during her illustrious writing career.

Crafting a perfect mystery

Agatha Christie's stories are like a puzzle box full of clues, misdirection and drama. But what are the essential elements of crafting a perfect mystery?

Setting

One of the most important decisions while designing any story is choosing the setting. Whether it was a remote island or yacht or a snow-stalled train stall, the author would always favour eerie and isolated locations, a trend that most of her stories follow. By doing so she limited the movement of her characters and build tension by forcing these plausible suspects to stay put, with the killer lurking among them.

In some cases, she would heighten the drama by making the characters strangers, unsure of who they could trust.

Characters

As a keen observer of human behaviour, she would often use peculiar traits or habits of the people around her to create authentic characters. However, one of the most popular criticisms of her novels is her use of two-dimensional characters that would easily reflect the stereotypes of her time. Future writers are advised not to emulate this trait of hers.

Language

It is a mystery writer's job to concoct stories that are complex and full of riddles and clues. Making it merely a balancing act between being clever and not confusing. The English author used simple, precise and accessible language to accomplish this task. The clarity of her language makes her stories palatable and engaging and can be credited with making her the 'Queen of mystery'.

Do plants have the ability to learn?

Plants do not store information the way we humans do, but they have a way of remembering - they store memories "in sophisticated cellular and molecular signalling networks". Called 'somatic memory', it is stored in the plant's body. And, this is what a plant passes down to its offspring.

The act of learning is usually attributed to animals. A few studies in the past have shown that plants can learn too. However, a new analysis suggests that plants are capable of more than just learning. What is it? Come, let's find out.

From floods and heat waves to drought and wildfires, extreme weather events caused due to climate crisis have been affecting natural wildlife habitats the world over. Such changes to their environment have forced animals to change their behaviour too - "altering their hunting and hibernation patterns and moving habitats". But animals aren't the only ones adapting to change. As the new research indicates, plants too are forced to "quickly adapt to survive. And, as part of this adaptation, they also "transmit these new traits on to their offspring" - in what is seen as teaching.

It may seem impossible that rooted as they are to the spot, plants are able to adapt, much less teach. But this is exactly what is happening. For instance, plants use the winter season to get ready for flowering in spring, which is the next season. With winters becoming shorter, some plants now have mechanisms in place that allow them "to avoid flowering in periods where they have less chances to reproduce". Plants do not store information the way we humans do, but they have a way of remembering - they store memories "in sophisticated cellular and molecular signalling networks". Called 'somatic memory, it is stored in the plant's body. And, this is what a plant passes down to its offspring. Researchers say this is not a genetic change, rather it is what they call 'epigenetics"; "they can change how an organism reads a DNA sequence". This contributes "to the long-term adaptation of plant species to climate change".

Did you know?

Epigenetics is the study of how your behaviours and environment can cause changes that affect the way your genes work. Unlike genetic changes, epigenetic changes are reversible. They do not change your DNA sequence, but they can change how your body reads a DNA sequence.

What is UPI and how it works?

UPI saves people from Cash on Delivery hassle and running to an ATM

As Prime Minister Narendra Modi pushes for a digital India, many of us may have used Unified Payments Interface (UPI). But do you know what it is?

What is UPI?

UPI is a system that allows multiple bank accounts into a single mobile app, thus, merging several banking features, seamless fund routing, and merchant payments under one umbrella.

The UPI has made bank-to-bank money transfers simple and secure, enabling everything from purchasing vegetables from roadside vendors to sending money to friends and relatives.

UPI was launched by the National Payments Corporation of India (NPCI) on April 11, 2016, by Raghuram G Rajan, then-Governor of RBI, at Mumbai.

Features

Some of the unique features of UPI is that it allows immediate money transfer through mobile phones round the clock 365 days.

Besides, it saves people from Cash on Delivery hassle, running to an ATM, or rendering exact amounts.

People can also pay multiple bills from a single mobile app via Utility Bill Payments, Over the Counter Payments, QR Code-(Scan and Pay) based payments.

As per the latest guideline issued by the NPCI, a person is allowed to use UPI to send a maximum of Rs 1 lakh per day. The restriction varies from bank to bank.

Besides, there is a cap on the total amount of UPI transfers that can be made in a day. Twenty transfers are permitted per day using UPI.

HOW TO REGISTER IN UPI ENABLED APPLICATION

What does an extraterrestrial whirlwind sound like?

When the Perseverance rover successfully landed on Mars in February 2021, it marked the beginning of its tasks, which included looking for signs of past Martian microbial life, cache rock, and soil samples for future return to Earth. While the rover is still at it, it has provided for another first already. Based on data provided by Perseverance, scientists have made the first-ever audio recording of an extraterrestrial whirlwind.

Not always on

The Perseverance rover is equipped with what is the first working microphone on the Martian surface. This microphone, however, is not on continuously. Far from it, in reality. This microphone records for about three minutes every couple of days.

This is partly the reason why it has taken this long to get the whirlwind recording, despite the fact that the rover landed in the Jezero where there's been evidence of nearly 100 dust devils, or tiny tornadoes of dust and grit, since Perseverance landed.

This was the first time that the rover’s microphone was on when one of these dust devils passed over the rovers. While there is definitely an element of luck, it wasn't entirely unexpected as it was only a matter of time before the microphone was on at the right time.

"The Martian” might not happen

Taken along with air pressure readings and time-lapse photography, the sound recording of the dust devil will help scientists understand Mars atmosphere and weather conditions better. The information gathered has already suggested that future astronauts on the Martian surface would not have to worry about gale-force winds blowing down antennas or habitats, as popularised by The Martian, the book and the movie of the same name.

In fact, there is reason to believe that the winds might have certain benefits. Scientists believe that the winds blowing grit off the solar panels of other rovers like Opportunity and Spirit might well be the reason why they lasted so much longer. Similarly, the lack of such winds and dust devils in the Elysium Planitia where the Insight mission landed could be a factor as to why that mission's operational period was planned to end in December 2022.

What was the mission of the Hubble Space Telescope?

A mission conceived as one for preventive maintenance turned out to be more urgent after four of the six gyroscopes on board the Hubble space telescope failed.

The Hubble space telescope has changed our understanding of the universe A telescope that was launched into low Earth orbit in 1990, Hubble still remains operational and continues to be a vital research tool. Following NASA's most recent review of Hubble's operations, it has been announced that NASA would support the observatory through June 2026, with estimates suggesting that it might be able to continue operations until the mid-2030s and even beyond.

Designed to be visited

While the longevity of the telescope is testament to the vision of those who conceived the mission, there's another crucial factor that has made it possible. Hubble was the first telescope that was designed to be visited in space. This meant that astronauts could not only perform repairs and replace parts, but also upgrade its tech with newer instruments. There have been five such missions that have taken place from 1993 to 2009. One such servicing mission in December 1999 turned out to be a life saver for the telescope.

After the first servicing mission in 1993 and the second one in 1997, the third to carry out preventive repairs was scheduled for June 2000. Since Servicing Mission 2 in February 1997, however, three of the six gyroscopes aboard Hubble had failed. With at least three working gyroscopes necessary for Hubble's operation, it prompted the managers to split Servicing Mission 3 (SM3) into two parts, SM3A and SM3B, with the former scheduled for December 1999.

An unexpected failure

 On November 13, 1999, a fourth gyroscope failed unexpectedly. With SM3A planned for the following month, this triggered NASA to place Hubble into safe mode. The safe mode was a sort of protective hibernation that prevented the telescope from making any observation. Hubble was in this state for over a month, waiting for the crew of SM3A to make their way.

With servicing mission veterans Steven Smith and Michael Foale at the helm, the seven-member crew aboard the Discovery Space Shuttle (STS-103) left for space on December 19. Within a couple of days, they manoeuvred close enough to Hubble such that it could be grappled with Discovery's robotic arm.

All six gyroscopes replaced

 The first of the three scheduled spacewalks took place over 8 hours and 15 minutes spanning December 22-23 (Central European Time, CET). Smith, along with fellow crew member John Grunsfeld, managed to replace all six of Hubble's gyroscopes. The entire astronomical community heaved a collective sigh of relief on receiving this news. The duo also replaced kits to prevent Hubble's batteries from overcharging.

While Hubble's main computer was changed in the second spacewalk that spanned 8 hours 10 minutes through December 23-24 (CET), the final spacewalk spanning 8 hours 8 minutes through December 24-25 (CET) saw a faulty transmitter and data tape recorder being replaced. Preliminary tests were then conducted to ensure that all of Hubble's systems, be it old or new, were performing satisfactorily.

Backs away slowly

Minutes into December 26 (CET), the Hubble telescope was released. Discovery then backed away from Hubble slowly. Having successfully performed the major objectives of the mission, the astronauts on board used the time remaining to stow away equipment, apart from making preparations for landing.

After orbiting the Earth 119 times and travelling more than 5 million km, Discovery made its way back. It performed a smooth night-time landing, touching down on the runway at the Kennedy Space Center in the U.S. on December 27. Hubble was successfully back in operation, and has been for over two decades since then.

What kind of writer is Dominique Lapierre?

French author Dominique Lapierre used a mix of reportage and historical narrative to spin stories of everlasting appeal. As the "City of Joy" and the world mourns the loss of the writer, here's a recap of his life and times.

What separates a journalist from an activist? Where is that thin line that you cross over to become part of the story, rather than write the story? More often than not, journalists struggle with the sense of purpose when they report from a battlefield or during catastrophes being faced with the dilemma whether to help the victims or focus on reportage. French author Dominique Lapierre was in the midst of major political upheavals and poignant moments in history, whilst also reporting from war zones. When the journalist turned into an author, and turned these narratives into best-selling books, he ensured that a part of the royalties would be used for humanitarian work.

The literary world mourned as Lapierre breathed his last on December 4. Kolkata also wept, shedding tears with the world. The author who became a household name after he wrote the 1985 novel ‘The City of Joy’ was 91 when he passed away due to age-related issues. The news was confirmed by his wife Dominique Conchon-Lapierre.

Early years

Born on July 30, 1931, in Chatelaillon, France, Lapierre was born to a diplomat father and a journalist mother. He started off the journey as a writer by writing travelogues. He later started reporting for the weekly news magazine "Paris Match" in the 1950s.

Literary partnership

It was whilst he was serving in the French army that he met American Larry Collins. Lapierre was 23 then. Collins later became a journalist. The two subsequently formed a deep literary partnership that propelled them to churn out hugely successful novels.

Six bestselling books!

The collaborative literary works of Lapierre and Larry Collins saw immense success. In all, 50 million copies of the six books Lapierre wrote along with Collins have been sold. These six bestsellers are O Jerusalem! (1972); Freedom at Midnight (1975); Is Paris Burning? (1965), The Fifth Horseman (1980); Is New York Burning? (2005); and Or I'll Dress You In Mourning (1968).

Lapierre's ode to India

 Lapierre always had a special connection with India. He showed his love for India even through his memoir, India mon amour (2010). But it was his novel The City of Joy that made him popular with the Indian crowd. The story revolves around the experiences of a rickshaw puller. In a PTI interview, Lapierre had said that the novel was like his "song of love for India, the place where I have been coming very regularly since the last 50 years. It has been an emotional journey for me where I have got a lot of love and support from the people".

Five Past Midnight in Bhopal: The Epic Story of the World's Deadliest Industrial Disaster (1997) is yet another book written by him. This was an investigative account of the 1984 Bhopal gas tragedy based on three years of research and interaction with survivors. This he wrote in collaboration with Javier Moro. In 2008, he was awarded India's third-highest civilian award, the Padma Bhushan.

A humanitarian

Lapierre was all about writing with a purpose. As a writer and journalist, he leaves behind a legacy. What we know is that Lapierre didn't stop with documenting the injustices but also tried his bit to address them.

His humanism is evident in how he founded the "City of Joy Aid", a non-profit humanitarian organisation based in Kolkata in 1981. He donated a large share of his royalties to support humanitarian projects. He supported many charitable projects in India such as refuge centres for children affected with polio, NGOs, schools, rehabilitation workshops, education programmes, and so on. Likewise, the royalties from the sale of the book on the Bhopal gas tragedy were used to give free medical treatment to the victims of the disaster.

Books to movies

Is Paris Burning? and The City of Joy were later made into movies by René Clément in 1966 and Roland Joffé in 1992 respectively.

What extinct species came back 2022?

The year 2022 has seen quite a number of species getting reintroduced into the wild while some were discovered. Here are a few animals and birds that made to our list of animals in spotlight.

TASMANIAN TIGER

The 1930s saw the marsupial Tasmanian Tiger go extinct. Now efforts are being taken to resurrect the animal using gene-editing technology. The $15-million project hopes to reintroduce the animal to Tasmania, its native place. This attempt is expected to bring back the ecological balance in the region. Seen here is a stuffed Tasmanian tiger which was declared extinct in 1936.

SNOW CRABS

A huge collapse in the population of snow crabs was found after 11 billion snow crabs disappeared off the coast of Alaska. The crabs are disappearing in the Bering Sea and scientists believe that global warming could have resulted in the vanishing of these crabs. The sea was warmer in the previous years and this could have been the reason for the mass die-off. The decline in the numbers were noted when the survey was conducted in 2021. The survey result was confirmed this year too and it was ascertained that the crabs didn't move to any other place, but disappeared. Their total numbers fell to about 1.9 billion in 2022, from 11.7 billion in 2018.

CHEETAH

The last cheetah died in India in 1947. And over 70 years after the animal was declared extinct in India, the country launched its ambitious programme "Project Cheetah to reintroduce cheetahs into the wild. Eight cheetahs including five females and three males were introduced as they were brought in from Namibia, southern Africa to Kuno National Park, Madhya Pradesh. Seen here is a cheetah after being released inside a special enclosure of the Kuno National Park in Madhya Pradesh.

IVORY-BILLED WOODPECKER

For long researchers believed that the ivory-billed woodpecker got extinct. But this year, a few researchers have claimed that the very bird which was declared extinct by the U.S. government was spotted in the forests of Louisiana. The researchers have claimed its spotting based on a series of grainy pictures and observations of the bird. Once relatively common, the numbers of ivory-billed woodpeckers started dropping with habitat loss due to human intervention and hunting. It is the largest woodpecker in the U.S.

APIS KARINJODIAN

Did you know that the last time a honey bee species was discovered in India was in 1798? And now, after a gap of 224 years, a new honey bee species endemic to Western Ghats has been discovered. Named Apis Karinjodian, the species has been classified as 'near threatened’ by the International Union for Conservation of Nature (IUCN). With the new addition, now we have a total of 11 species of duster honey bees in the world.

WILD BISON

The year saw the wild bison get reintroduced to the U.K. for the first time in thousands of years. The species classified as near threatened was introduced into a woodland in Kent. The bison is being reintroduced as part of the Wilder Blean project. The idea for the reintroduction of the species is to restore natural landscapes. It is also a rewilding attempt to check if the animal's behaviour can help transform a commercial pine forest into a natural forestland.

GREAT INDIAN BUSTARD

The Great Indian Bustard (GIB) came into focus once again this year when the Supreme Court of India asked if a Project GIB on the lines of Project Tiger could be launched to protect the bird. Found mainly in Rajasthan and Gujarat, the GIB has been labelled as critically endangered by the International Union for Conservation of Nature (IUCN). The SC bench asked this whilst hearing petitions on the situation of the bird and their deaths in large numbers due to electrocution from high-transmission power lines.
