Current notions of people’s malevolent or dark character suggest three distinct traits: Machiavellianism, narcissism, and psychopathy. However, using dark profiles (i.e., individuals combination of these three dark traits) rather than linear statistics, we here demonstrate that the individuals who are high in Machiavellianism and psychopathy share a unified non-agentic and uncooperative character (i.e., irresponsible, low in self-control, unempathetic, unhelpful, untolerant), while individuals high in narcissism have a more unique character configuration expressed as high agency and, when the other dark traits are high, highly spiritual but uncooperative. In other words, based on differences in their associations to the light side of character (i.e., a ternary construct: self-directedness, cooperativeness, and self-transcendence), the Dark Triad seems to be a dyad rather than a triad.
The Tennessee River Basin is one of the most important freshwater fish biodiversity hotspots, but little is known regarding the fossil record of fishes from this area. This study fills in the zoological history through the identification, processing, and reporting of 41 unique species from 10 sites that span the entire basin over the last part of the Pleistocene ice age (10,000 to 30,000 years ago). This study represents one of the most comprehensive descriptions of North American late Pleistocene fishes and provides evidence of early assemblage structure, several extirpation events resulting from ice sheet recession, and little known extinct taxa.
In this manuscript, we present the first ever strain-resolved complete genomes from metagenomics for five members of the bacterial phylum Peregrinibacteria, that were sampled from filtered groundwater obtained from an aquifer adjacent to the Colorado River near the town of Rifle, CO, USA. Importantly, strain-variation in these bacteria is not observed in their ribosomal rRNA, rather it manifests primarily in large extracellular proteins which may function in attachment to other cells.
Top Veterinary journals were compared to top medical journals. Veterinary articles had several deficiencies that may limit the validity of the interventions used in veterinary medicine. There is urgent need of improving the research performed in veterinary medicine, by improving methodology and number of randomized trials and by enrolling real clinical patients.
This is a study that is an overview of the global patterns of concentrations of persistent organic pollutants (POPs) in marine finfish. Based on this review of 100s of peer-reviewed studies, we show three major items: (1) POPs are in seafood from across the world's oceans. (2) Despite the ubiquitous presence of POPs, the concentration in the consumable meat of marine finfish is highly variable. Within one region and one group of fish species, we may find concentrations of POPs that vary by 1000-fold. (3) By looking at these data through time, we show that the concentration of POPs have been dropping consistently for the past 30 years at a rate of 15-30% per decade.
Since 9/11, the American media has focused attention on the possibility of "homegrown" terrorist threats. Despite media focus on the Muslim community as a source of domestic terrorism, terrorist acts associated with Islamic fundamentalists only account for 2.3% of all attacks occurring between 2000-2009. Right-wing groups, in the form of sovereign and militia movements, and left-wing groups, in the form of environmentalism, remain legitimate threats. On the other hand, the overall number of domestic terrorist acts has decreased since the 1970s, while lethality of—that is, the number of deaths caused by—these acts has increased.
Gene expression data was used to identify key enzymes in the gut of a major storage pest, the red flour beetle. The expression of genes encoding enzymes in the major feeding stages, larvae and adults, was compared to that of non-feeding stages, eggs and pupae. The data contribute to the comprehensive study of protein digestion in the beetle and identify key enzymes to target for pest control strategies.
Xinjiang is a region which is the furthest region from the oceans and used to be an isolated area; Xinjiang is a poorly-known region for invasive species. Surprisingly we found the area has invaded by hundreds of alien species already and the economic and ecological impacts of those alien species are profound.
Glacial cycles during the last Ice Age induced changes in the distribution of species. When distribution ranges expand, closely related species might get in contact and interbreed. By documenting higher historical levels of migration of the nuclear genome between species compared to contemporary levels, researchers suggest that current genetic structure resulted form limited dispersal across the isthmus and depression barriers.
Differential scanning calorimetry of whole Escherichia coli treated with the antimicrobial peptide MSI-78 indicate a multi-hit mechanism with ribosomes as a novel target. Drug resistant infections are becoming a huge problem and antimicrobial peptides (AMPs), have been proposed to be useful for designing new antibiotics that will be less susceptible to resistance development. Most researchers focus on how AMPs interact with the lipid bilayer of bacteria. Using a technique (differential scanning calorimetry = DSC) to study the effect of one AMP (MSI-78) on all parts of the bacteria, researchers found MSI-78 doesn’t just target lipid bilayers - it messes up ribosomes as well.
