BIG CATS EVOLVED AS TIGERS

In a first, scientists have mapped the tiger genome, including that of the Bengal Tiger, and identified genetic mutations that helped the big cat evolve to become a top predator. Scientists also sequenced the genomes of the lion and snow leopard, in an effort to conserve and protect the endangered species. The study provides clues to how big cats evolved to become top predators with superior muscle strength and a carnivorous diet, 'BBC News' reported. Researchers found that the tiger shares 96 per cent of its genes with the house cat. The only cat to have its DNA mapped was the domestic one. Researchers led by Yun Sung Cho at the Personal Genomics Institute, Genome Research Foundation in Suwon, South Korea, sequenced the genome of a Siberian tiger. The individual, Taegeuk, is a nine-year-old male from Everland Zoo in South Korea. The team then sequenced the DNA of four other big cats - the African lion, snow leopard, white Bengal tiger and white African lion. This enabled the researchers to compare how the genes matched up in different members of the cat family. Genetic signatures show how big cats gained their superior muscle strength, the ability to digest large amounts of meat and a keen sense of smell. The research also gives genetic clues to how the white lion gained its pale coat and how the snow leopard adapted to the snowy mountain ranges. The study was published in the journal Nature Communications.

MUNSHI PREMCHAND STORIES IN COMIC FORMAT

Stories by modern Hindi and Urdu literary legend, Munshi Premchand are now available in comic format published by Amar Chitra Katha. The comic books in Hindi detailing two stories by the late literary phenomenon, is part of the publisher's contemporary classics section, which began in 2012 with stories by author Ruskin Bond. "We are launching the comics at the World Book Fair and it is our tribute to Premchand. The idea is to make his stories familiar with children," Reena Puri, Editor, Amar Chitra Katha told PTI. The stories "Buddhi Kaki" (The old Aunt) and "Do Bail" (Two Oxen) have been scripted and illustrated by Pratima Singh and Surendra Murthy. The English version of the comics translated by Nandini Nair is also set for launch within a few weeks, says Reena. The books are priced at Rs 50 each. "Buddhi Kaki" first published in 1921 is the story of an old childless widow who craves for love after she bequeaths her entir…

WORLD's FIRST UNDERWORLD TENNIS COURT IN DUBAI

Dubai, which boasts of the world's highest tennis court, may also become home to the first underwater tennis centre where spectators can watch games from below or above the sea life through a massive glass dome. Krzysztof Kotala, a Polish architect who owns a studio in Warsaw, is currently seeking investment from local players to make the ambitious project a reality. Interestingly, the proposed location for the project (arguably one of the world's lowest tennis courts) is just next door to the highest tennis court atop the Burj al Arab skyscraper in Dubai. "There is not an investor but I would like to get interest (from them) as I think it is a good idea," Kotala, 30, was quoted as saying by a local magazine. When asked why he chose Dubai for his project, Kotala said the Gulf city had a rich tradition of tennis. "This will be something original. This should be somewhere where there is the tradition of tennis. Dubai is perfect for this idea," he said. The in…
