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
After being exclusive to iOS for more than a year, Clubhouse on Sunday debuted its Android app on the Play Store. The move will allow Android users to experience the popular audio-based social network for the first time. However, the beta app is currently live in the US but the company says the Android app will come to other English-speaking markets and then the rest of the world.
