The Bio Web site EurekaMag.com publishes insights into all places of the bio sciences including biology, agriculture, horticulture, forestry, geography, environment and well being. Drawing from this pool of scientific disciplines, it publishes articles, reviews and insights on biological topics such as those which have lately attained attention. Although the Bio-Investigation Category contains more than 36 million references, most of the evaluations are integrated in the Bio-Keyword Category, the Bio-Keyphrase Category and in the Bio-Reviews Category of the on-line science magazine. All content is now offered on a user-friendly and quick Mobile m.EurekaMag.com Site.

The EurekaMag.com insight into Drosophila covers these little fruit flies which have been heavily utilised as a model organism in general genetics, population genetics, cell-biology, biochemistry, and specially developmental biology. As a result, extensive efforts are produced to sequence drosphilid genomes. The insight covers Drosophila’s presumptive circadian pacemaker neurons and their response to nocturnal dim light. At a nighttime illumination comparable to quarter-moonlight intensity, the flies improve activity levels and shift their typical morning and evening activity peaks into the night. In parallel, clock protein levels are lowered, and clock protein rhythms shift in opposed direction in subsets of the previously identified morning and evening pacemaker cells. Other scientific studies show that Drosophila utilizes components of an identified pathway to respond to hypoxia. Hypoxic exposure quickly induces exploratory behavior in larvae and arrests the cell cycle. These behavioral and cellular responses are diminished by an inhibitor of NO synthase and by a polymorphism affecting a form of cGMP-dependent protein kinase.

EurekaMag.com presents an insight into solar flares which are significant energy releases at the sun’s surface ejecting electrons, ions, and atoms by way of the sun’s corona into space. Such emitted radiation can impact earth’s ionosphere and disrupt long-range radio communications which, in turn, can disturb operation of radars and other devices. The EurekaMag review presents the effects of solar flarees on corn borer adults. The results proved that both the daily and annual catches were substantially modified by the Q-indexes, expressing the various lengths and intensities of the solar flares. On days with high Q-indexes, the number of catches are considerably lower whereas in years with low Q-indexes an improve as high as 45 percent can be knowledgeable in the number of individuals collected. One more study shows that in January 2005, the solar active region NOAA AR 10720 produced 5 potent solar flares. Throughout this key solar activity several pronounced variations in the ground-level cosmic ray intensity were recorded. These flares created energetic solar cosmic rays that caused a giant enhance in the count rates of the ground-based cosmic ray detectors. At southern polar neutron monitor stations the boost of the count rate reached a number of thousand percent.

The EurekaMag.com insight into killer whales covers the toothed predatory whale belonging to the oceanic dolphin loved ones which can be found in all oceans, from Arctic and Antarctic regions to tropical seas. Individual populations of killer whales specialize in particular kinds of prey. Some feed exclusively on fish, even though others hunt marine mammals such as sea lions, seals, walruses and even other whales. The EurekaMag insight covers identification of causes of death of stranded killer whales. Parasites were identified in most killer whales. The nematode Anisakis simplex was located in the stomach of 57 percent of the animals and the acanthocephalan Bolbosoma capitatum was present in the intestine of all specimens. An unidentified cestode was identified also in the intestines of 14 percent of the people. The high infections of Bolbosoma capitatum and Anisakis simplex were not directly associated with the result in of death. In the stomachs of 4 females, beaks of at least eight specimens of the oceanic and epipelagic species Ommastrephes bartramii had been identified. Genetic analysis of the killer whale Orcinus orca proofs that it is an abundant, extremely social species with reduced genetic variation. Researchers located no consistent geographical pattern of international diversity and no mtDNA variation inside some regional populations. The regional lack of genetic variation among killer whales appears to be due to the strict matrilineal expansion of nearby populations.
