1 - One of the biggest icebergs broken away from Antarctica
One of the biggest icebergs ever recorded has broken away from Antarctica. The giant block is estimated to cover an area of roughly 6,000 sq km; that's about a quarter the size of Wales.
An infrared sensor on the American space agency's Aqua satellite spied clear water in the rift between the shelf and the berg. The European Sentinel-1 satellite-radar system should also have acquired imagery to confirm the break.
Currents and winds might eventually push it north of the Antarctic where it could become a hazard to shipping.
2 - Ahmedabad declared as world heritage city by UNESCO
41st session of UNESCO's world heritage committee announced India’s Ahmedabad city as a World Heritage City at a meeting held in Krakow, Poland. Gujarat’s Ahmedabad city is believed to be founded by Ahmed Shah, 600 years ago. With this announcement, Ahmedabad became India’s first World Heritage City.
Other competitors in the list were Delhi and Mumbai. Ahmedabad received votes from 20 countries due to its peaceful co-existence of dominant Hindu, Islamic and Jain communities. There were only two other cities from Indian sub-continent in the list- Nepal’s Bhaktpur and Sri Lanka’s Galle.
3 - ‘White tiger’ spotted in the Nilgiris for the first time
A rare ‘white tiger’ with a pale skin color has been spotted for the first time in the Nilgiris by a wildlife photographer, Nilanjan Ray at an undisclosed location on a recent trip to the Nilgiri Biosphere Reserve.
It is yet to be ascertained whether the white tiger is a true genetic mutant. As per the scientists, genetic mutation among tigers changes an amino acid responsible for the normal colour being formed, resulting in “natural polymorphism”. According to the scientists, white tigers lack pheomelanin, which is responsible for the red-yellow hue in the skin coat.
