Pollution is a big problem, particularly from industry which pumps unwanted metals into the soil just about everywhere in the world. Getting rid of this had been an issue looking for a solution for decades. The answer could be at hand from a very weird source. Fish sperm has a property making it ideal for the purpose. It literally hoovers up the metal particles. The sperm contains high amounts of DNA. This contains phosphate which strongly attracts metals. The metal/phosphate compound can be taken out with neodymium magnets consisting of trivalent iron, dysprosium and neodymium. In Italy herring sperm was first identified as being useful in cleaning up the environment. With salmon being bred commercially, it is seen as a better source of fish sperm. The substance has been thrown away as waste until now. ✴ Science by Ty Buchanan ✴ http://www.adventure--australia.blogspot.com/ http://www.tysaustralia.blogspot.com/ http://adventure--australia.blogspot.com/atom.xml . . . . ....

We have been told that magnets have wonderful powers: not only can they be used to generate electricity, they can be used to reduce pain, etc. Now a new use has been found: crocodiles have been fitted with magnets to stop them returning to their home area. In Florida they have been carrying out an experiment to find out if magnets can be used to disrupt crocodiles' homing ability. Though small in number, crocodiles do cause problems when they wander into populated areas. People fear them even though they are are small and usually run away from humans. In contrast alligators are larger and more dangerous. Once a "rogue" crocodile has been caught it is relocated to an area free of humans. Magnets are put on the crocodile's head. This affects the animals natural homing abilities so that it remains where it is placed. The population has increased because fewer wander onto roads. This is a good thing as the species is endangered. http://www.adventure--australia.blogsp...
