If you're like me and you have a visceral reaction to the image above—if it makes your skin crawl, your hair hurt, and your stomach turn—you can count yourself among the trypophobic. According to its Facebook page, which is more than 4,000 members strong, trypophobia is fear of clustered holes. It is usually small holes in organic objects, such as lotus seed heads or bubbles in batter, that give trypophobics the extreme willies, triggering reactions like itchy skin, nausea and a general feeling of discomfort. (A picture of a candy bar with a pattern of small air bubbles did me in. Goodbye, dear chocolate. For now.)
Just about everyone can think of some memory he or she would rather forget. For some, it's something like a relationship gone wrong, or high school. For others -- like soldiers returning from war zones -- those bad memories can be highly disruptive, impeding the ability to live a normal life. But Puerto Rican researchers may have found a way to reduce the fear associated with our memories by injecting a naturally occurring chemical directly into the brain, replacing anxiety with feelings of security.
Security agencies have long used the canine nose to sniff out contraband like explosives, drugs, human traffic and the like by picking up the scent of criminals’ illegal cargo. Now British scientists are developing two sensor systems that sniff out the criminals themselves by zeroing in on a specific pheromone emitted when humans are in stressful, fearful situations.
