How do sharks navigate through the deep, dark world under the seas? Scientists now say they have the very first evidence which shows that sharks use Earth's magnetic fields like a GPS to move across seas and oceans. There are no “street lights” or physical barriers to guide them during their long-distance voyages and migrations. Yet they appear to identify and reach their destinations thousands of kilometres away with precision. Saying that navigating through a three-dimensional ocean is one of the most impressive feats of evolution, the researchers said there is a possibility that sharks use their electrosensory organs to read Earth's magnetic field like a map or atlas. Published in the latest issue of Current Biology journal, the research tested the previously unverified theory that sharks used magnetic fields to navigate. For this, they focussed on sharks that were smaller. The researchers also tried to identify the shark species known to return to specific locations every

     Sri Lanka's sacred city of Anuradhapura is an unlikely place to be enmeshed in a fantastic tale of UFOs and otherworldly happenings. Locally known as Rajarata (Land of Kings), the Unesco World Heritage Site was the first established kingdom on the island (in 377 BC) and is at the heart of Sri Lanka's Buddhist culture. Today, it's one of the nation's most visited places, attracting devoted pilgrims from around the country to its ancient Buddhist temples and giant dome-shaped stupas. But this holy city is also home to something far more curious. Here, in Ranmasu Uyana (Golden Fish Park), a 40-acre ancient urban park surrounded by three Buddhist temples, is a chart that's alleged to be a map to unlock the secrets of the Universe. Measuring around 1.8m in diameter, Sakwala Chakraya (which translates to "Universe Cycle" in Sinhalese) is shallowly carved onto a low rock face among the protected park ruins. Its front facade can only be seen from ground leve
