Cities affect biological evolution, but traditionally researchers focus on the biophysical influence of urban environments. Instead, this Review explores how the social processes of religion, politics...

Plant cells are totipotent, meaning individual cells have the potential to develop into a full organism, a property unique to the zygote for animals. However, in most species for most cells, plant cells are not spontaneously totipotent, since they must be treated with specific hormone combinations to unlock their totipotency. Species within the Kalanchoe genus is unique as they spontaneously develop foliar embryos that are fully realized plantlets with shoot and root from notches along the edges of leaves. We speculate that the progenitor cells that give rise to these foliar embryos are totipotent, and we are using single cell techniques to identify & characterize them. In addition to being a fundamental process for plant biology, we foresee unlocking totipotency has many biotechnological applications, such as faciliating genetic transformation and the development of synthetic organs of biomanufacturing.

Pigeons seem right at home in St. Louis. You can see flocks perching on rooftops and power lines, waiting for a chance to grab a stray scrap of food or dirty a windshield. Daisy Lewis Cities have push...

Brown lizards in New Orleans carry more lead in their blood than any other animal on record — levels that would kill humans — yet they seem unfazed, according to new Tulane study.

Os seres humanos mudam a paisagem urbana com atividades religiosas, culturais e políticas, que, por sua vez, podem influenciar a evolução de animais e plantas urbanos

The St. Louis socioeconomic and racial dividing line known as the Delmar Divide separates people, and new research suggests it also segregates wildlife.
