“With most medications, like valium, the anti-anxiety effect you get only lasts when it is in your system. When the valium goes away, you can get rebound anxiety. When you take ketamine, it triggers reactions in your cortex that enable brain connections to regrow. It’s the reaction to ketamine, not the presence of ketamine in the body that constitutes its effects.” And this is exactly what makes ketamine unique as an antidepressant.

Is the ‘bad boy’ appeal a myth? The current study assessed how individuals evaluate potential romantic partners who display either low, medium, or high levels of DT traits for short-term (STR) and long-term (LTR) relationships. The Dark Triad (DT) consists of three personality traits—narcissism, Machiavellianism, and subclinical psychopathy […] Study 1 demonstrated people with a male preference (mostly women) perceived medium levels of the three traits as the most attractive STR. For Study 2, both men and women found the low levels the most attractive for both STRs and LTRs. […] results suggest the concept of DT is not as attractive even for STRs unless it is accompanied by physical attractiveness [and] that men tend to be less selective than women overall when it comes to choosing partners —- for both short-term and long-term relationships.
While dogs kill some 30,000 people annually, only 100 shark attacks are documented worldwide each year, and fewer than 15 percent of these are fatal. Still, he wants to understand why sharks attack when they do. […] among some terrestrial predators such as tigers and leopards, a select few “problem individuals” are thought to be disproportionately responsible for attacks on humans. […] Some scientists have dismissed the notion of “problem sharks” as unlikely […] But in a new study in Conservation Letters, Clua and his colleagues present the very first evidence for his theory, by documenting three sharks that have been responsible for repeat attacks. The findings shine a new light on shark personality and suggest indiscriminate culling may not be an effective method of reducing shark attacks. […] For Clua, problem shark behavior suggests a new strategy for preventing attacks. He and his colleagues call for efforts to systematically fish sharks, without killing them, to collect DNA and attach tags or notch their dorsal fins for easy identification. Then, if a shark bites a person, DNA can be swabbed from the victim’s wound to identify the culprit, which can be selectively targeted and killed. Mourier isn’t convinced this solution could be widely implemented. For one, “you need at least a few hours and even days to get the results of the DNA extraction and identification, so during that time the shark is likely to be far away and the chance to find it again is very low in most cases,” he writes.
