Why eukaryotes, not bacteria, evolved complex multicellularity
Prokaryotic single-celled organisms, the ancestors of modern-day bacteria and archaea, are the most ancient form of life on our planet, first appearing roughly 3.5 billion years ago. The first eukaryotic cells appeared around 1–1.5 billion years la.....»»

Soil pH drives microbial community composition: Study shows how bacteria work together to thrive in difficult conditions
Though a founding concept of ecology suggests that the physical environment determines where organisms can survive, modern scientists have suspected there is more to the story of how microbial communities form in the soil......»»
Early dark energy could resolve cosmology"s two biggest puzzles
A new study by MIT physicists proposes that a mysterious force known as early dark energy could solve two of the biggest puzzles in cosmology and fill in some major gaps in our understanding of how the early universe evolved......»»
How bacteria actively use passive physics to make biofilms
When we think about bacteria, we may imagine single cells swimming in solution. However, similarly to humans, bacterial cells often socialize, using surfaces to coalesce into complex heterogeneous communities called biofilms. Within a group, bacteria.....»»
