ASTEROID THAT ELIMINATEDDINOSAUR GAVE RISE TO

AMAZON RAINFOREST

T he asteroid impact that wiped out thedinosaurs from the Earth also gavebirth to the Amazon rainforest, says a

new study. In an analysis of thousands of fossilpollen and leaves, researchers found that thecataclysmic asteroid impact that resulted inthe destruction of nearly 75 per cent of all theterrestrial life on the Earth drastically restruc-tured the tropical forests. It also set the stagefor the evolution of what has become one ofthe planet's most-diverse ecosystems — theneo-tropical rainforest, according to the study.

1According to the findings, lateCretaceous rainforests were charac-

terised by an open canopy environment.

2However, plant diversity declined byroughly 45 per cent at the Cretaceous-

Paleogene (K/Pg) boundary and extinc-tions were widespread, particularly amongthe seed-bearing plants

3While the forests recovered over thesubsequent six million years,

angiosperms or the flowering plants, cameto dominate the forests, said the study

4This transition led to the closedcanopy structure and the layered, ver-

tical distribution of plant biodiversity thatdefines the modern tropical rainforests

SALMA HAYEK JOINS LADY GAGAAND ADAM DRIVER IN RIDLEY

SCOTT'S 'HOUSE OF GUCCI'

S alma Hayek is the latestA-lister in the cast ofveteran filmmaker

Ridley Scott's 'House of Gucci'.The much-awaited movie willfeature pop star Lady Gaga asPatrizia Reggiani, the ex-wifeof Guccio Gucci's grandsonMaurizio Gucci (to be played byAdam Driver). Hayek will essaythe role of Pina Auriemma, whowas a clairvoyant friend ofReggiani, reported Deadline.

Reggiani was abandoned after 12years of marriage by MaurizioGucci in 1985 for a youngerwoman. She was tried and con-victed of orchestrating her ex-husband's assassination on thesteps of his office in Italy in1995 She got the nickname theBlack Widow during the trialand served 18 yearsbefore being releasedfrom prison in 2016

DIDYOUKNOW

Amid a surge in Covid-19 cases inthe country, the Indian MedicalAssociation (IMA) has written toPrime Minister Narendra Modisuggesting that vaccination beallowed for all people above theage of 18 years

India reported the highest-ever1,26,789 new Covid-19 cases in thelast 24 hours, as per the Unionhealth ministry data on Thursday.India has given more than nine croredoses of vaccine, and Thursday'stally stood at 9,01,98,673

1 The IMA also suggestedthat private sector familyclinics should be included

actively in the vaccination drive,along with the private hospitals

2 Making vaccination certifi-cate mandatory for entering

public places andreceiving products

under the publicdistribution system,

was also part of thesuggestions made by

the association

3 It said thatthe availabil-ity of vacci-

nation with all doc-tors and family

physicians will have apositive impact on theinoculation drive SHARE YOUR VIEWS AT TOINIE175@GMAIL.COM

Let’s remember children’s immunesystems are different from theadults. So, their immune responsescan vary at different ages— frominfancy through the teenage years.The major challenge remains on get-ting a clarity on how safe it is to inoc-ulate the young population DR SANGITA KESKAR, head of patholo-gy, Chinmaya Mission Hospital,BengaluruThe major challenge with the gov-ernment in inoculating the youngpopulation lies with the demand andsupply of the vaccine. However, it

can be dealt with, if the govt takesup the programme first in areas,where the infection rate is high.DR PRAVIN GARG, consulting physician,

Ahmedabad

The database of youth above 18years is still not in place. Also, withmalls, pubs, cinemas, etc, open, itconveys a wrong message to theyoungsters that Covid affects onlythe elders. They may not be ready totake the jab. DR A SRIKANTH, secretary, IndianDental Association, Hyderabad

STUDENTS' TAKE As thesupply ofvaccine islimited, Ifeel prece-denceshould begiven to the

priority groups, whichinclude the senior citizensand those with co-morbidi-ties. However, in Covidhotspots, where the posi-tive cases are high, peopleabove the age of 18, shouldbe vaccinated to break thechain. SAI KRISHNA PRIYA, class X,

GTAVM, Chennai

Our country has a humon-gous working-population agedbetween 20 and 40. It’s timethey are inoculated, lest ittakes a huge toll on the healthof the masses, which in turncould effect our economy. HARSH KUMAR AGARWAL,

class X, National English School, Kolkata

With the cases of coronaviruson a deadly surge, I feel Covid vac-cine should be made compulsoryfor everyone above the age of 18,as it’s the young population, whoare venturing out from theirhomes for different purpose. ADITYA SINGH, class XII, Sadhu

NORTH KOREA BECOMES FIRSTcountry to drop out of Tokyo Olympics

North Korea's sports ministryhas said that its nationalOlympic Committee hasdecided not to participate in

the 32nd Olympic Games, in order to pro-tect its players from the world publichealth crisis caused by Covid-19.However, Japan's Olympic Committee saidthat North Korea has not yet notified itthat it wouldn't participate.

FYI: All International OlympicCommittee member countriesare required to take part ineach Games under theOlympic charter

It will be the first time forNorth Korea to miss a SummerOlympics since 1988, when itboycotted the Seoul Games during the Cold War The pandemic has alreadypushed back the Tokyo Gamesto July 23, 2021 — originallyscheduled for 2020 — and theorganisers have scrambled toput in place anti-virus measures, such as banning international spectatorsto ensure the safety of athletes and residents While North Korea claims to be coronavirus-free, outsiders remain doubtful about whether the country has escaped the pandemic entirely,given its poor health infrastructure, and a porous border it shares withChina, its economic lifeline

SECTION-VWRITING SKILL

Q5. A Read the following passageand make a tree diagram: [5]

There are three major types ofpollution: air pollution, water pol-lution and soil pollution.

A major source of air pollutionis the burning of fossil fuels. Vehi-cle and factory emissions are com-mon sources of this type of air pol-lution. Air pollution contributes torespiratory problems such as asth-ma, lung cancer, chronic bronchi-tis, and other lung ailments. Nitro-gen and sulphur oxides in the aircontribute to acid rain.

A major source of water pollu-

tion is runoff from agriculturalfields, industrial sites, or urban ar-eas. Runoff disrupts the waterbody's natural balance. Raw sewageis another type of water pollutant.When sewage gets into the drink-ing water supply, serious stomachand digestive issues may result,including the spread of dis-eases such as typhoid ordysentery. A third source ofwater pollution is trash. Im-properly disposed of items,such as plastic bags, fishingline, and other materials mayaccumulate in the water and leadto the premature death of animalsthat get tangled within the garbage.

Soil can become polluted by in-dustrial sources or the improperdisposal of toxic chemical sub-stances. Common sources of soilpollution include asbestos, lead andoveruse of pesticides. Soil pollution

Vast archives at JFKLibrary help bring

‘Hemingway’ to lifeA new Ken Burns documentary on the life of Ernest Hemingway is

shedding new light on one of America’s greatest writers

Anew Ken Burnsdocumentary onErnest Heming-way powered byvast but little-

known archives kept at the JohnF Kennedy Presidential Libraryand Museum in Boston is shed-ding new light on the acclaimednovelist.

‘Hemingway,’ premiered onPBS (three consecutive nightsfrom April 5), takes a more nu-anced look at the author andhis long-standing reputation asan alcoholic, adventurer, out-doorsman and bullfight-lovingmisogynist who struggled withinternal turmoil that eventu-ally led to his death by suicideat age 61.

The truth about the manmany consider America’s great-est 20th-century novelist whoseconcise writing style made him

an outsized celebrity who be-came a symbol of unrepentant

American masculinity is muchmore complex, said LynnNovick, who collaborated withBurns on the three-part film.

The archives contain Hem-ingway’s manuscripts including‘The Sun Also Rises’ and ‘ForWhom the Bell Tolls’, personalcorrespondence and about 11,000photographs.

While considered the ar-chetype of American manhood,the truth about Hemingway’smasculinity was more complex,the filmmakers found. As a child,Hemingway’s mother treatedhim and one of his sisters astwins. He explored gender flu-idity both in his books and inlife, letting his hair grow as hiswives cropped theirs short.

Novick’s favourite part ofthe collection were Hemingway’smanuscripts, many handwrittenon store-bought notebooks.

In an interview withblogs.sciencemag. org, au-thor Walter Isaacson saidthat three great innova-tion revolutions have

shaped the modern world: theatom, the bit (information cod-ed in binary digits), and thegene. He explored the first inhis book ‘Einstein,’ through thework of famed scientist AlbertEinstein; and the second in

‘Steve Jobs’, which chronicledthe digital revolution unleashedby pioneer Steve Jobs.

With ‘The Code Breaker’,Isaacson takes a deep dive into

the world of gene andgene-editing techthrough the work of

Nobel award win-ning biochemist

Jennifer Doudna, co-discover-er of the CRISPR gene-editingtechnology. According to him,this is the ‘third great wave ofinnovation,’ one where hu-manity is taking control of itsevolutionary future.

Starting out like any tradi-tional biography,Isaacson firstsheds light onDoudna’s earlylife. As a sixthgrade student,Doudna was fas-cinated with‘The Double He-lix’, the 1968 au-tobiographicalaccount by sci-entist James D

Watson who, along with fellowscientist Francis Crick, werethe first ones in the world toidentify the structure of DNA,thus revolutionising biochem-istry, and winning the NobelPrize. Enthralled by the bookthat chronicled the intense dra-ma behind one of humanity’smost significant discoveries,

Doudna decided to pursue sci-ence. Interestingly, she was ad-vised that ‘girls don’t do sci-ence’ by her guidance coach.Thankfully, she didn’t pay anyheed to that advice!

The book follows her earlycareer moves, and her work onRNA (Ribonucleic acid) thateventually gave her a head startin the emerging bioscience fieldof gene editing as the co-dis-coverer of CRISPR. Besides ex-plaining how the use ofCRISPR is revolutionisingtherapies including fightingsickle cell, cancer, congenitalblindness and Alzheimer’s;Isaacson sheds light on theemergence of biohackers who‘want to democratise biologythrough citizen science’; andthen, delves into moral impli-cations of gene editing.

According to Isaacson weare now entering the a life-sci-ence revolution that will com-bine the existing age of digitalcoding with genetic coding tousher in a new kind of human.Are you ready for it?

Walter Isaacson’s ‘The Code Breaker: JenniferDoudna, Gene Editing, and the Future of theHuman Race’ offers an interesting insight into theCRISPR technology – a tool that can edit DNA.Designer babies anyone?

SO, WHAT IS CRISPR?

Www.livescience.org describes it as:“CRISPR technology is a simple yetpowerful tool for editing genomes. Itallows researchers to easily alter DNAsequences and modify gene function.Its many potential applications includecorrecting genetic defects, treating andpreventing the spread of diseases andimproving crops. However, its promisealso raises ethical concerns.CRISPR stands for: Clustered RegularlyInterspaced Short Palindromic Repeat

SolifugaeSolifugae is an order of animals in the classArachnida, known variously as camel spiders, windscorpions, sun spiders or solifuges. It includesmore than 1,000 described species in about 153genera. Despite the com-mon names, they are nei-ther true scorpions nortrue spiders. Much like aspider, the body of a solifugid has two tagmata(segments): an opisthosoma (abdomen) behindthe prosoma (that is, a combined head and tho-rax). Most species of Solifugae live in dry climates.

The first 17 days will see games being played out in Chennai and

Mumbai with defending champions Mumbai Indians taking on

Royal Challengers Bangalore in the opener in Chennai

IPL 2021 a great opportunity toprepare for T20 WC

➨ The virus has cast its shadow on the league in the

build-up stage with some positive cases among both

players and support staff. But with a strict bio-bub-

ble in place for the games, the BCCI would be hop-

ing for a smooth run just like the previous edition

in the UAE. If one looks at the bigger picture, the

14th edition of IPL assumes greater significance as

it is being held in a T20 World Cup year and that too

in the sub-continent.

➨ If Virat Kohli will keep a ‘Hawk Eye’ on the per-

formances of his probable list of players, it won’t be

any different for an Eoin Morgan or a Kieron Pol-

lard, who would also be preparing for the mega-event

while giving it their all for their respective franchises.

Why Mumbai Indians arefavourites in IPL

➨ For Rohit, the most successful captain in the

‘IPL Universe’ with an unprecedented five titles,

he could well walk away with a sixth trophy

and the first title hat-trick of this league. Mum-

bai Indians, perhaps in the near two decade

existence of Twenty20 format, is a side that

will be remembered for its aura.

➨ If Rohit fails, then Quinton de Kock

will certainly succeed. If both fail,

Ishan Kishan and Surya Kumar Ya-

dav could scare the daylights out of

the opposition.

➨ And if the top-order is blown away, then the in-

domitable Pandya brothers (Hardik and Krunal)

will be there to pummel oppositions’ bowlers.

➨ On the outfield, Kieron Pollard will save those ex-

tra runs apart from the trademark big hits always

expected of him and also bring in the change of pace

suited for the Chennai track. Trent Boult, with his

swing, and Rahul Chahar, with his googlies, will

also test the batsmen.

➨ Mumbai Indians can only lose on their bad days and

on good days, they are going to be a nightmare as Eng-

land captain Michael Vaughan has already warned.

Rohit’s opposite number is the national captain, who

is ready to open once again but the squad composi-

tion of RCB doesn’t inspire the highest confidence.

Will Maxwell finally justifyhis hefty price tag?

➨ Glenn Maxwell has again been picked for a bomb

(`14.25) and New Zealand’s Kyle Jamieson has

been made an overnight multi-millionaire by

the franchise despite him being untested on

Indian dust-bowls. Devdutt Padikkal will

be in his second season with teams

analysing him way more and Yuzven-

dra Chahal seems to have lost his

mojo.

➨ Mohammed Siraj and Navdeep Sai-

ni do not inspire the highest confidence

in white ball cricket at least despite their

gutsy performances in Australia early this year.

STRENGTHS

➨ RR boasts of a number of de-

structive batsmen. Jos Buttler and

Ben Stokes are two match-winning

players who can trample any op-

position while Samson is a mine-

field of talent.

➨ South Africans David Miller and Mor-

ris are two other powerful strikers

and England’s T20 specialist Liam

Livingstone can turn the match on

its head. Last season’s revelation, all-

rounder Rahul Tewatia, has also

showcased his ability to whack the

ball outside the park.

WEAKNESSES

➨ For Royals, the problem is their weak

Indian core which hasn’t been con-

sistent. Samson has rarely performed

in five straight games in any of the

editions in the past few years. Pacer

Jaydev Unadkat, bought for `11.5

crore in 2018, has been unable to de-

liver while Manan Vohra has been

brilliant only on rare occasions.

➨ This leaves the team with young-

sters, including Riyan Parag and

pacer Kartik Tyagi, who has shown

flashes of brilliance, Yashasvi Jaisw-

al and pacer Kartik Tyagi, who was

also impressive.

OPPORTUNITIES

➨ Samson’s form and consistency have

always been a question mark. He has

failed to capitalised on the handful

of chances provided to him in T20Is.

With Suryakumar Yadav and Ishan

Kishan doing brilliantly on their T20

debuts, the Kerala wicketkeeper

batsman’s chances to make the

Indian team for the World Cup have

taken a hit.

➨ A perfect opportunity for him to prove

his leadership skills and a consistent

performance with the bat will signif-

icantly strengthen his case for selec-

tion for the upcoming T20 World Cups.

THREATS

➨ With Samson at the helm, his lack of

experience in the role and the impact

that it might have on his batting are

factors that must be taken into ac-

count. The flamboyant right-hander

may not be able to play with the same

freedom now that he is captain. His

inexperience might also cost the Roy-

als dearly in crunch situations.

➨ The team won matches on the back

of some brilliant individual perfo-

rmances but struggled to work as a

cohesive unit last season. Consistency

will be the key.

➨ The team is heavily dependent on

Archer. While they have Morris to

rely on, the pace attack is weak in the

26-year-old England pacer’s absence.

The franchise will desperately hope

Archer joins the side at the earliest.

➨ With a weak Indian contingent, com-

prising several rookies and overre-

liance on their foreign recruits, there

is real threat the Royals would once

again not qualify for the playoffs.

THE SQUAD

➨ Sanju Samson (c & wk), Jos Buttler

(wk), Ben Stokes, Yashasvi Jaiswal,

Manan Vohra, Anuj Rawat, Riyan

Parag, David Miller, Rahul Tewatia,

Mahipal Lomror, Shreyas Gopal,

Mayank Markande, Jofra Archer,

Andrew Tye, Jaydev Unadkat, Kar-

tik Tyagi, Shivam Dube, Chris Mor-

ris, Mustafizur Rahman, Chetan

Sakariya, KC Cariappa, Liam Liv-

ingstone, Kuldip Yadav, Akash Singh.

Ben Stokes, part of the RRsquad since 2018, has led histeam to several victories

Last season’s wooden spooners, RR have made some changes in management as well as the squad ahead

of the new season. Sanju Samson replaced Australian Steve Smith, who was released as skipper. Coach

Andrew McDonald has also gone with Sri Lankan legend Kumar Sangakarra stepping in as director of

cricket. Here’s a SWOT analysis of the side that will take on Punjab Kings in Mumbai on April 12
