An experimental weapon that the U.S. military is working on failed after it was launched from a test range in Alaska on Monday prompting the initiation of a self-destruct sequence. Pentagon said that the Advanced Hypersonic Weapon, which is part of the Conventional Prompt Global Strike (CPGS) program, a collaboration of Army Space and Missile Defense Command and the Army Forces Strategic Command, that aims to develop a weapon with the ability to destroy targets anywhere on Earth in under an hour, exploded just four seconds after it was launched. Controllers identified problems and the issue  prompted the abortion of the mission to secure the safety of the public. U.S. Defense Department spokesperson Maureen Schumann said that no one was hurt because of the incident, which happened at a test range in Kodiak Island in Alaska shortly 4 am EDT on Monday albeit the incident caused damage to the launch facility. "We had to terminate," Schumann said. "The weapon exploded during takeoff and fell back down in the range complex. Fortunately, no people on the ground were injured. There was damage, but I'm not sure of the extent of it at this time." Eyewitnesses said that the weapon went off course immediately after it took off and eventually exploded. The Department of Defense said that an extensive investigation by officials from the U.S. Army, Navy, and the Missile Defense Agency is being conducted to determine the cause of the failure. Results of the investigation, however, may not be available soon as it may take weeks or even months before the findings are concluded. "Due to an anomaly, the test was terminated near the launch pad shortly after lift-off to ensure public safety," the Department of Defense said in a statement. "Program officials are conducting an extensive investigation to determine the cause of the flight anomaly." The weapon, which is developed by the U.S. Army and the Sandia National Laboratory and travels at hypersonic speed covering 3,500 miles in less than one hour, could be used to target satellite-identified terrorists located thousands of miles away and to strike weapons of mass destruction. Defense analyst James Acton, from the Carnegie Endowment for International Peace, however, said that Pentagon has not specified the weapon's mission although it could be used as an anti-terrorist tool. Some also see the weapon as part of an arms race with other countries, notably China, which also tested a hypersonic system earlier this year.

Steganography is a process of secret communication where a piece of information or secret message is hidden in such a way that the very existence of the secret information remains concealed without raising any suspicion in the minds of the viewers and hence preventing its detection. This is generally achieved by embedding a piece of information inside another piece of innocent looking information and can be a spatial or time or transform domain method. All these methods hide information in different types of media such as text, image, audio, video etc. Amongst these varieties of available media, digital images are more commonly used for implementation of data hiding techniques because of their size and popularity. This paper uses a spatial domain LSB substitution method for information embedding and Arnold transformation is successively applied twice in two different phases in order to achieve higher security. The system is tested and validated against a series of standard gray scale images and the results thus obtained are found to be highly promising. © 2012 Springer-Verlag GmbH.

Microbial diversity constitutes the most extraordinary reservoir of life in the biosphere that we have only just begun to explore and understand. In this research work, microbial diversity of three tropical scented flowers Rose, Jasmine and Marigold were studied. Representative samples of flowers were collected aseptically from various sites of Bhubaneswar of district Khurda, Orissa during the period from the mid of February to July 2007. Maximum possible number of culturable bacteria, fungi and yeasts were obtained from three stages of flowers and a gradual pattern in the density and diversity of microbes was observed. A total of 71 bacterial strains were obtained from all the three flowers and were categorized into 17 different genera as per their biochemical characterization. Grams reaction of these isolates indicates 42 were Gram -ve rods and 29 were Gram +ve, of which 19 were bacilli and 10 cocci respectively. The predominant bacteria isolated includes Bacillus sphaericus, Bacillus cereus in Jasmine, Bacillus lentimorbus, Serratia plymuthica in marigold and species of Flavobacterium, Xanthomonas in Rose flowers. Acetobacter aceti and E.coli were isolated from all the flowers. Pigmented bacteria like Serratia plymuthica and Serratia marsescens have been isolated from the marigold during the course of study. Curvullaria sp and Candida sp. was isolated from Rose, however only a Penicillium sp was isolated from Marigold whereas no fungi or yeast was isolated from Jasmine. In this study the presence of microflora has been elucidated but their significance and the impact on the respective flowers is yet to be revealed.

Brackish water is the most extraordinary reservoir of bacterial community with an adaptability of tolerance to saline condition. In this research work, the halotolerance of the bacterial isolates were screened for identification and characterization of halotolerant bacteria from the brackish water of the chilika lake,Odisha. Representative samples of water was collected aseptically from four important sites of the lake viz Barkul,Kalupada Ghat,Parikuda and Rambha during the period from January to June 2012. Maximum possible number of culturable bacteria were obtained and screened for halotolerance. A total of 25 bacterial isolates were obtained and almost all the isolates survived upto 1 M NaCl but only one bacteria tolerated above 2.5M NaCl and was extremely halotolerant .This strain was identified as Staphylococcus sp.13CC. and designated with accession number KF657328. It is a potential urease producer which is an important industrial enzyme. Further assay of enzyme is yet under study.
