A new review explains how nitrogen-fixing, buoyancy-regulating cyanobacteria exploit low N:P ratios and thermal ...

In eukaryotes, the cell cycle consists of four discrete phases: G 1, S, G 2, and M. The S or synthesis phase is when DNA ...

Eukaryotic plankton are an essential and highly diverse component of marine ecosystems. A research team has established their global geographic distribution using DNA data and a probabilistic model.

One of the most important and puzzling events in the evolution of life has been the origin of the first complex eukaryotic cells. Almost all lifeforms that we can perceive with the naked eye, such as ...

Tiny relatives of our cellular ancestors reshape long protrusions within minutes and pull themselves across surfaces using ancient actin machinery.

A simulated 8-degree heatwave in Lake Taihu mesocosms revealed that prokaryotic and eukaryotic microbial communities follow ...

Why is Christian Science in our name? Our name is about honesty. The Monitor is owned by The First Church of Christ, Scientist, and we’ve always been transparent about that. The church publishes the ...

Contaminated samples have evidently created some confusion in the timetable of life. On the basis of ultra-clean analyses, an international team, including scientists from the Max Planck Institute for ...

A eukaryote is any cell or organism that possesses a clearly defined nucleus. Eukaryotic cells form the foundation of complex, multicellular life, including apple trees, mushrooms, fish and humans.

Current hypotheses suggest that all life on Earth evolved from a common ancestor that diversified into the variety of organisms seen today. Scientists propose that the eukaryotic branch of this family ...

For billions of years after the origin of life, the only living things on Earth were tiny, primitive cells resembling today’s bacteria. But then, more than 1.5 billion years ago, something remarkable ...
