WASHINGTON : Nasa on Friday set a launchdate of May 27 for its first astronaut mis-sion from US soil in nearly ten years.

Nasa administrator Jim Bridenstinetweeted that billionaire entrepreneurElon Musk’s space company, SpaceX, willsend two Nasa astronauts to the Interna-tional Space Station aboard its Falcon 9rocket from Florida — marking the com-pany’s first mission carrying humansaboard.

“BREAKING: On May 27, @Nasa willonce again launch American astronautson American rockets from Americansoil!” Bridenstine wrote on Twitter.

The US space agency had previouslysaid the mission, in which Nasa astro-nauts Bob Behnken, 48, and Doug Hurley,52, will ride SpaceX’s Crew Dragon cap-sule to the space station, would launchsometime in May.

As with most high-profile missions, thenew date could slip. If all goes as planned,the mission would mark the first timeNasa launches its astronauts from US soil

Star ‘dance’ around black hole confirms Einstein’s theory

6 new coronaviruses discovered in batsPress Trust of India

WASHINGTON/ NEW DELHI: Scientists have dis-covered six new coronaviruses in bats inMyanmar — the first time these viruseshave been found anywhere in the world.

The findings will help understand thediversity of coronaviruses in bats andinform global efforts to detect, preventand respond to infectious diseases thatmay threaten public health, particularlyin light of the ongoing Covid-19 pan-demic.The researchers will evaluate thepotential for transmission across speciesto better understand the risks to humans.

CORONAVIRUS FOUND IN 2 INDIAN BAT SPECIES: STUDYAs the world grapples with the novel coro-navirus pandemic, researchers havefound the presence of a different kind ofcoronavirus — bat coronavirus (BtCoV)— in two bat species from Kerala, Hima-chal Pradesh, Puducherry and TamilNadu, according to an ICMR study. Thereis no evidence or research to claim thatthese bat coronaviruses can cause diseasein humans, said Dr Pragya D Yadav, sci-entist at the National Institute of VirologyPune and the first author of the study.

LONDON: Using paper towels to dry yourhands is substantially more effectivethan hand dryers for removing virusesincluding the Covid-19, according to anew study.

According to the researchers, handdrying is important to minimise thespread of dangerous microbes — includ-ing the novel coronavirus — since failureto remove them increases transfer toenvironmental surfaces and increasesthe opportunities for transmission andspread.

For the findings, researchers from theUniversity of Leeds in the UK investi-gated whether the way people dry theirhands in a public toilet made a differenceto the way Covid-19 is transmitted. IANS

SANTIAGO : Astronomers in Chile using one ofthe world’s largest telescopes have founda star ‘dancing’ around a black hole in theMilky Way just as Albert Einstein mighthave predicted more than a century ago.

Einstein’s General Theory of Relativity,published in 1915, is a foundation of mod-ern physics. It has long helped scientistsunderstand the forces of gravity.

But Thursday’s announcement fromthe European Southern Observatory(ESO), an intergovernmental group ofEuropean astronomers that operates inChile, proves the theory applies even to astar some 26,000 light years from the Sun.

Nearly 30 years of measurements, ESOscientists said in a statement, allowedthem to follow the star as it traced arosette-shaped orbit around the “super-massive” black hole in the Milky Way.Their discovery proved Einstein, and nothis predecessor Isaac Newton, was right.Newton believed it would travel in anellipse-like pattern.

With all sporting events sus-

pended, most training centres and

national camps shut, what are

athletes doing with their forced

leisure time? Everyday a top ath-

lete will talk about her or his expe-

rience of dealing with the Covid-19

pandemic. This is Fouaad Mirza,

who ended India’s 36-year wait for

an individual Equestrian medal

at the 2018 Asian Games. The only

Indian rider to win a Tokyo Olym-

pics quota place, Mirza is now in

Germany, where around 1,40,000

positive cases have been reported

(as of April 19).

I am currently living in Berge-dorf village near Ganderkesee town in Northwest Germany. It’s a secluded place with farmlands and a population of, maybe, fewer than 100.

Following an announcementby (German Chancellor) Angela Merkel, fresh guide-lines were issued that included a ban on public gatherings of more than two people and main-taining a 1.5-metre distance at

all times when in public space.

LIVING ALONEAs I live in an apartment alone, I have mostly stuffed food items like pasta, rice, coffee — things that can last for a longer period. There is a Finnish rider in our training base as well as other German riders, not to mention my trainer Sandra Auffarth, a former world champion and Olympic medallist. I am lucky that my sponsors, Embassy Group, has extended all the support possible. Now that the Olympics are postponed, I would certainly turn down the intensity of training. I now have one extra year to prepare. Some of the horses in my team are in their prime years or are sort of at the end of their prime years. To get one more good year out of them, we will have to be very careful about managing them, fitness wise, health-wise and so on. Everything happens for the best.

AIMING FOR THE NEXT LEVELI also had some other goals of try-ing to compete at the five-star level, it is a level above the Olym-pics which is four-star. I had to hold off that goal because I had to save my horses for the Olympic Games. Now that there is a little

bit more time, I could tryto achieve the goal tocompete at a five-star.

Our competitionseason starts in April

and ends in October inEurope. In that case if it

starts in eight months,the season is over bythen . Now, I think weall have to do every-thing in our power tostop this virus from

spreading and so thatwe get back to our normallives again.

MONUMENTS SOAK IN SILENCE! With normal life badly affected and the entire country locked down since the Covid-19 outbreak, some of India’s most popular landmarks, that are known for the frenetic energy of lakhs of sightseers who mill around them every day, have been replaced with eerie stillness. The imposing India Gate in New Delhi and the iconic Taj Mahal in Agra are just two of such countless monuments that are together sporting rarely seen deserted looks.

Born on June 8, 1955, in Lon-don, he is the eldest of foursiblings of computer scien-tists Mary Lee Woods and

Conway Berners-Lee who hadworked on Ferranti Mark 1, thefirst commercially built computer.

EDUCATIONAs a child who attended schools inLondon he was a keen train-spotterwho learned about electronicswhile playing with his model rail-way. He studied at The Queen’sCollege, Oxford, for three yearswhere he received a first-classBachelor of Arts degree in physics.While at university, Berners-Leemade a computer out of an old tele-vision set.

CAREERBerners-Lee worked as an engi-neer at the telecommunicationscompany Plessey in Poole, Dorset.In 1978, he joined DG Nash in Fern-down, Dorset, where he helped cre-ate type-setting software for print-ers. He worked as an independentcontractor at CERN in 1980. He pro-posed a project based on the con-cept of hypertext, to facilitate thesharing and updating of informa-tion among researchers. To dem-

onstrate it, he built a prototype sys-tem named ENQUIRE. After leav-ing CERN in 1980, he worked atJohn Poole’s Image Computer Sys-tems, Ltd, in Bournemouth, Dor-set. In 1989, CERN was the largestinternet node in Europe, and Bern-ers-Lee saw an opportunity to joinhypertext with the internet.

WORLD WIDE WEBBerners-Lee wrote his proposal inMarch 1989 and, in 1990, redistrib-uted it. It then was accepted by hismanager, Mike Sendall, who calledhis proposals ‘vague, but exciting’.He used similar ideas to thoseunderlying the ENQUIRE systemto create the World Wide Web, forwhich he designed and built thefirst Web browser. His softwarealso functioned as an editor (calledWorldWideWeb, running on theNeXTSTEP operating system), andthe first Web server, CERN HTTPd(short for Hypertext Transfer Pro-tocol daemon).

FIRST WEB SITEBerners-Lee published the firstwebsite, which described theproject itself, on December 20, 1990;Available to the Internet from theCERN network, it explained what

the World Wide Web was, how peo-ple could use a browser and set upa web server, as well as how to getstarted with your own website.

LATER CAREERIn June 2009, then British PM Gor-don Brown announced that Bern-ers-Lee, together with Nigel Shad-bolt, would work with the UK gov-ernment to make data moreaccessible and open to people thatneeded it on the web sitedata.gov.uk.

PERSONAL LIFEBerners-Lee married NancyCarlson, a programmer ana-lyst, in 1990 and they had twochildren.The couple wasdivorced in 2011. He thenmarried Rosemary Leith,director of the World WideWeb Foundation.

AWARDS & HONOURSBerners-Lee was knighted byQueen Elizabeth II in 2004 “for ser-vices to the global development ofthe internet.” He was elected a Fel-low of the Royal Society in 2001. Hewas appointed to the Order ofMerit, an order restricted to 24 (liv-ing) members.

INVENTOR OF THE WORLD WIDE WEBTIMOTHY JOHN BERNERS-LEE: This pioneering computer scientist was on the Time list of the 100 Most Important People of the 20th century. The Professorial Fellow in Computer Science at Oxford, MIT professor and fellow of the Royal Society was knighted in 2004.

In 1994, Berners-Leefounded the World

Wide Web Consortium (W3C) at the Massachu-setts Institute of Tech-nology. It comprised companies that were willing to create stan-dards and recommenda-

tions to improve the quality of the Web. And rather than restrict access to the emerging technology, Berners-Lee made his idea available freely without the need for patent and royalties.

In 2016, Berners-Lee was awarded

the ACM AM Turing Award “for inventing the World Wide Web, the first web browser, and the fundamental protocols and algo-rithms allowing the

Web to scale.” Many universities, including Manchester, Harvard and Yale, conferred honorary degrees on Berners-Lee. In 2009, the US National Academy of Sciences elected him as a foreign associate.

In a Times article inOctober 2009,

Berners-Lee admitted that the pair of slashes (‘//’) in a web address were “unnecessary” and that it could have initially been designed without the slashes.
