Knowing Me, Myself, And I: What Psychology Can Contribute To Self-Knowledge
How well do you know yourself? It"s a question many of us struggle with, as we try to figure out how close we are to who we actually want to be. In a new report in Perspectives on Psychological Science, a journal of the Association for Psychological Science, psychologist Timothy D. Wilson from the University of Virginia describes theories behind self-knowledge (that is, how people form beliefs about themselves), cites challenges psychologists encounter while studying it, and offers ways we can get to know ourselves a little better.

Health Chair's Stance On Pet-Free Flights Very Disappointing: Lung Association, Canada
The Canadian Lung Association expressed disappointment in federal Health Committee Chair Joy Smith"s stance on the issue of Air Canada and WestJet"s policy to allow pets to travel in the passenger cabin of airplanes. The Lung Association launched an online campaign for pet-free flights in July following the decision by Air Canada to join WestJet in offering pet-free flights, despite the serious risks it presents to passengers and crew with asthma, COPD and severe animal allergies.

Secrets Of Scorpion Venom Revealed By Genetic Analysis

Transcriptomic tests have uncovered the protein composition of venom from the Scorpiops jendeki scorpion. Researchers writing in the open access journal BMC Genomics have carried out the first ever venom analysis in this arachnid, and discovered nine novel poison molecules, never before seen in any scorpion species. Yibao Ma worked with a team of researchers from Wuhan University, China, to study the sting of S. jendeki, a member of the family Euscorpiidae, which covers Europe, Asia, Africa, and America. He said, "Our work greatly expands the current knowledge of scorpion venoms. We found ten known types and nine novel venom peptides and proteins. These molecules provide a rich, hitherto-unexplored re for drug development as well as clues into the evolution of the scorpion venom arsenal". To humans, the sting of scorpions from the Euscorpiidae family tend to be quite mild - about as painful as a mosquito bite. S. jendeki venom has never been studied before. The researchers found that it contains ten known poisons, with markedly diverse modes of action and nine new types of venom peptide, whose biological effects are yet to be determined. The scorpion itself, however, is considered harmless - probably because it cannot deliver enough of the poison to cause any damage to a healthy human. Interestingly, neurotoxins, which are major poisons in the venom of another scorpion species that can kill humans, were not found in the S. jendeki venom. Ma concludes, "Many types of venom peptides and proteins have been obtained from diverse scorpion species. Some are widely distributed among scorpions from different families, while others, like some of those discovered in our study, appear to be restricted to particular scorpion lineages. The presence of these common and uncommon venom molecules among different lineages reflects the dynamic evolutionary process of the scorpion venom arsenal".
