Here is some good news for the fans of DC comics superhero "Aquaman" - Thanks to its namesake "Aquaman crystal" they too may soon be able to swim deep into the oceans without lugging around heavy air tanks. That's because the man-made chemical compound which was unveiled by a team of researchers from the University of Southern Denmark on September 30th, has the capacity to absorb as much as 160 times the amount of oxygen that is in the atmosphere. According to the scientists, a spoonful of the substance could store all the oxygen that is present in a normal-sized room.
