Ever had an itchy nose or, worse, an unreachable spot on your back that drives you mad? Now imagine an itch that refuses to go away, no matter how hard or long you scratch. That persistent itch, or pruritus, may actually be one of the skin’s first lines of defense against harmful invaders, according to neuroimmunologist Juan Inclan-Rico of the University of Pennsylvania. “It’s inconvenient, it’s annoying, but sensations like pain and itch are crucial. They’re ever-present, especially when it comes to skin infections,” says Inclan-Rico, a postdoctoral researcher in the Herbert Lab at ...

It feels like narcissism is everywhere these days: politics, movies and TV, sports, social media. You might even see signs of it at work, where it can be particularly detrimental. Is it possible to keep a workplace free of destructive, manipulative egotists?  More and more organizations have come to San Francisco State University’s experts in organizational psychology asking for help doing just that. In response, University researchers developed a tool for job interviews to assess narcissistic grandiosity among potential job candidates. San Francisco State Psychology Professors Kevin Eschleman and Chris ...

You have likely not spent much time thinking about the uterus of the fruit fly, Drosophila melanogaster. But then, neither have most scientists, even though Drosophila is one of the most thoroughly studied lab animals. Now a team of biologists at the University of California, Davis, has taken the first deep look at the Drosophila uterus and found some surprises, which could have implications not just for understanding insect reproduction and potentially, pest control, but also for understanding fertility in humans.  The work is published Oct. 25 in Proceedings of the National Academy of Sciences.  Drosophila have been a favorite subject for ...
