Itch is an unpleasant sensation that evokes a desire to scratch. The skin barrier is constantly exposed to microbes and their products. However, the role of microbes in itch generation is unknown. Deng et al. show that Staphylococcus aureus, a bacterial pathogen associated with itchy skin diseases, directly activates pruriceptor sensory neurons to drive itch.

Mendieta et al. used fMRI to measure brain activity in fans of rival soccer teams during match play. This image shows the contrast of winning and losing in the ‘good fanatic brain.’ It shows in warm colors the activity related to a significant victory. The blue scale represents the activation related to a significant loss; this pattern is congruent with the Mentalization Network, which suggests a rationalization process of the pain evoked by the losing scenario.

Trilobites are extinct arthropods that dominated the faunas of the oceans of the Paleozoic era. During their time on Earth, which lasted much longer than the dinosaurs, between 521 and 252 million years ago, they survived two major episodes of mass extinctions and dominated ocean floor ecosystems. There are more than 20,000 known trilobite species.
