U.S. Navy patent hints at a new underwater sound weapon

U.S. navy has taken a different approach to the underwater weapons by making the most of the acoustic energy. A recent patent filed by them has revealed of a new powerful weapon that makes use of sonar to generate “acoustic remote cavitation’ that could destroy torpedoes, mines, and many other hinders. The acoustic source and target can be located in unconfined underwater space and at a distance of at least 100 m apart. The underwater cavitation could be used in superfast sub and missiles. The idea is pretty different i.e. using acoustic energy instead of any bombs or missiles to destroy the targets. It is no doubt a new pin on the idea of underwater weapons. Via: DangerRoom

Bionic nose to detect explosives

A new biosensor nose has been successfully developed by the researchers of Temple University School of Medicine that sniffs explosives. To build this biosensor Danny Dhanasekaran and his colleagues genetically engineered a yeast strain with rat olfactory signaling machinery and thereafter by linking it to the expression of green fluorescent protein. Associate Professor of Biochemistry at Temple’s Fels Institute for Cancer Research and Molecular Biology Danny Dhanasekaran said: We suspected that harnessing the potential of the olfactory system, which can detect innumerable chemical agents with unparalleled sensitivity and selectivity, would be of immense value in the detection of environmental toxins and chemical warfare agents even at sublethal levels The yeast cells are then cloned individually with rat olfactory receptors and when the olfactory receptor “smells” the odor of DNT or an ingredient in the explosive TNT, the biosensor turns fluorescent green. The forecast also reveals that day is not far when this bionic nose will be used to detect other hazardous gases and landmines. Via: I4u
