Journal Club: Neural circuits and social status spur zebrafish to swim or flee
Should I stay or should I go? In the zebrafish (Danio rerio), two competing neural circuits determine whether an animal swims or turns tail and escapes. Social status can tip the balance between these circuits, leading dominant and subordinate animals … Continue reading

Journal Club: Female flies fight back against mate-guarding by males
After mating, males of many species take steps to keep their partners from having sex with other males. But some females may have evolved tricks to foil these measures. Researchers studying the fruit fly Drosophila melanogaster have discovered that when … Continue reading

Journal Club: Rule-breaking microbe lacks mitochondria
Mitochondria, organelles central to cellular metabolism and energy production, are typically a hallmark of the eukaryotic cells that make up plants, animals, fungi, and many other organisms. Now scientists report the first known example of a eukaryotic organism that lacks … Continue reading

Journal Club: Tasmanian devils hit with another contagious cancer
Cancers aren’t usually contagious, but a tiny number of them can spread when diseased cells move from one animal to another. One such cancer, an aggressive facial tumor, has wiped out large numbers of Tasmanian devils in Australia over the … Continue reading
