Printed Paper Speaker

Scientists at Chemnitz University of Technology in Germany have developed paper thin speakers which can be printed on rolls of paper called T-Paper. The paper holds two layers of conductive organic polymer with a piezoelectric layer in between that vibrates to create the sound. T-paper can be shaped into a circle and act as a hanging loudspeaker at events like tradeshows or as part of museum exhibits to broadcast audio information.

VLF Space Barrier

NASA scientists have discovered an energy barrier around the earth that protects us from radiation and that is accidentally man made. The barrier is made of VLF (very low frequency) radio waves, which are generally used to communication with underwater submarines but have been leaking into the atmosphere.

Space Spiders

Someone decided that it was a good idea to put spiders on the International Space Station! Experiments with the space spiders (!) have shown that the spiders need a point of reference when building their webs and that light can be used as that reference in the absence of gravity. With no point of reference the spiders spin symmetrical webs in zero-g.

Fish Farmers

Researchers at Griffith & Deaking universities have found proof that longfin damselfish have domesticated mysid shrimp. These damselfish farm algae for food, and use the mysid shrimp feces as fertilizer. They even protect the shrimp from other fish outside the farm that try to eat the shrimp.
