The Midas cichlid, Cichlasoma citrinellum, is a polychromatic fish that occurs in Nicaragua. All of these fish start life as normally colored, cryptic individuals. In some populations a few fish change into conspicuously colored morphs, most frequently gold. When kept in unmixed color groups, golds and normals grow at the same rate; but when they are mixed, growth of the golds becomes faster an...

All popular web browsers offer a “private browsing mode.” After a private session terminates, the browser is supposed to remove client-side evidence that the session occurred. Unfortunately, browsers still leak information through the file system, the browser cache, the DNS cache, and on-disk reflections of RAM such as the swap file. Veil is a new deployment framework that allows web developers...

We describe a method based on fluorescence in situ hybridisation (FISH) that allows the identification of individual cells by electron microscopy. We hybridised universal and specific fluorescein-labelled oligonucleotide probes to the ribosomal RNA of prokaryotic microorganisms in heterogeneous cell mixtures. We then used antibodies against fluorescein coupled to sub-nanometer gold particles to...

Fish and other organisms are affected by pesticides which pollute the natural water through agricultural runoff. The aim of this study was to determine the acute toxicity of botanical pesticide, neem gold, and two synthetic pesticides, permethrin and monocrotophos, which are extensively used in agricultural farms. The mortality rate of Cyprinus carpio was monitored under laboratory conditions f...

This study was set to determine the antimicrobial activities of brine salting, chlorinated solution, and oil frying treatments on enteric bacteria and fungi in Rastrineobola argentea fish from fish landing beaches within L. Victoria basin of western Kenya. Statistical differences in effectiveness of the different treatment methods was determined by single factor ANOVA, and paired two-tail t-Tes...

Mercury (Hg) concentration in fish depends on feeding strategies and age/size within the species as well as on water parameters related to acidity and Hg speciation. We chose two species of piranhas (Serrasalmus aff. eigenmanni and Serrasalmus rhombeus) to test their suitability as markers of Hg bioaccumulation. The results of Hg concentrations in piranhas of the Rio Negro, with no history of g...

In a world where we are constantly bombarded with countless images of Islamic terrorism, violence, and danger, it is not surprising that we have come to associate all aspects of Islamic society with malevolence. This destructive way of thinking has impacted the way we—as Westerners— think about, portray, and perceive Muslim men and women. While Muslim men are often depicted as hostile, cruel, a...
