Did microbes assist life in colonizing land?

All living organisms exist and function only in cooperation with an abundance of symbiotic microorganisms, and have developed together with them over the course of the earth's history. This central finding of modern life ...

Scientists develop methods to validate gene regulation networks

A team of biologists and computer scientists has mapped out a network of interactions for how plant genes coordinate their response to nitrogen, a crucial nutrient and the main component of fertilizer. The work, published ...

Complex life might require a very narrow habitable zone

Since the Kepler Space Telescope was launched into space, the number of known planets beyond the solar system (exoplanets) has grown exponentially. At present, 3,917 planets have been confirmed in 2,918 star systems, while ...

Rethinking planetary climate controls

Yale researchers have provided a new explanation for why Earth's early climate was more stable and warmer than it is today.
