In the 1980s, scientists first noticed circles of DNA interspersed among the normally linear chromosomes of eukaryotic nuclei. Little is known about these molecules, which are called extrachromosomal circular DNA (eccDNA). Variation in eccDNA appears to be biologically significant; development of an organism often comes with increased numbers of eccDNA, for example, and certain types…

The yeast Candida albicans lives on and even inside many of us. Most of the time, its silent presence goes unnoticed, but this fungus can turn on its host, causing infections ranging in severity from annoying to life-threatening. For the yeast to become pathogenic, some of the C. albicans must transform from small, round cells…

When you catch a nasty cold, curling up in bed to sleep may be the only activity you can manage. Sleeping in response to stress isn’t a uniquely human behavior: many other animals have the same reaction, and it’s not clear why. While the circadian sleep that follows the pattern of the clock has been…

Over three centuries, as many as a million enslaved people were shipped to the Colombian port of Cartagena. From this hub of the slave trade, European colonists took Africans to labor in many places across the Americas, including the gold mines of the Chocó region. Today, people from Chocó often proudly identify as Afro-Colombian, while…

When a mutation arises in an egg or sperm cell, it could be evolutionarily important. But if a mutation occurs in somatic tissue instead, the result could be cancer. Mutations in the germline and soma not only have contrasting consequences, they also arise at different rates that may reflect the balance of DNA damage and…
