Multicellularity has evolved numerous times across the tree of life. One of the most fundamental
distinctions among multicellular organisms is their developmental mode: whether they …

The transition to multicellularity enabled the evolution of large, complex organisms, but early
steps in this transition remain poorly understood. Here we show that multicellular complexity…

By nature of their small size, dense growth and frequent need for extracellular metabolism,
microbes face persistent public goods dilemmas. Genetic assortment is the only general …

Pediatric oncology protocols frequently include multiple oral medications administered at
varied dosing schedules, often for prolonged periods of time. Nonadherence to protocol-…

The prevalence of multicellular organisms is due in part to their ability to form complex structures.
How cells pack in these structures is a fundamental biophysical issue, underlying their …

The evolution of multicellularity set the stage for sustained increases in organismal complexity
1 , 2 , 3 , 4 – 5 . However, a fundamental aspect of this transition remains largely unknown: …

All multicellular organisms develop through one of two basic routes: they either aggregate
from free-living cells, creating potentially chimeric multicellular collectives, or they develop …

Multicellular complexity is a central topic in biology, but the evolutionary processes underlying
its origin are difficult to study and remain poorly understood. Here we use experimental …

A key step in the evolutionary transition to multicellularity is the origin of multicellular groups
as biological individuals capable of adaptation. Comparative work, supported by theory, …

A survey questionnaire was mailed to residents and faculty at a midwestern medical school
to assess male and female attitudes toward colleagues' pregnancies. A total of 67%(N= 97) …
