How Birds Master Courtship Songs
TEHRAN (FNA)- By studying how birds master songs used in courtship, scientists at Duke University have found that regions of the brain involved in planning and controlling complex vocal sequences may also be necessary for memorizing sounds that serve as models for vocal imitation. ( 09:15:20 - 2012/09/18)



Nuclear Fusion: Magnetically Imploded Tubes
TEHRAN (FNA)- Magnetically imploded tubes called liners, intended to help produce controlled nuclear fusion at scientific "break-even" energies or better within the next few years, have functioned successfully in preliminary tests. ( 09:03:37 - 2012/09/18)



Modified Cellulose Acetate Nanofilters Applied to Separate Poison from Water
TEHRAN (FNA)- Iranian researchers successfully synthesized and modified the performance of cellulose acetate nanofilter membranes in order to separate nitro-aromatic poisons from water. ( 17:24:10 - 2012/09/17)



Iran Produces New Drug to Treat Heart Failure
TEHRAN (FNA)- Iranian scientists developed and produced a new type of medication for the treatment of heart failure, breaking the US and Israel's monopoly in the field. ( 11:24:11 - 2012/09/17)
