A new study has shown that birds, by providing sandy islands with organic fertilizers, help promote the growth of plants that strengthen shorelines and protect them from erosion. This effect is especially important in the context of rising sea levels.
Scientists have discovered a molecular switch that enables plants to enter into symbiosis with nitrogen-fixing bacteria. This breakthrough could pave the way for the development of cereal crops capable of supplying themselves with nitrogen, thereby reducing agriculture's reliance on fertilizers.
A reanalysis of data from the Galileo spacecraft has revealed traces of ammonia on Jupiter’s moon Europa. This discovery suggests possible cryovolcanic activity and increases the likelihood of a subsurface ocean that remains liquid and resists freezing.
Scientists have estimated how many planets in our galaxy could potentially support intelligent life, and found that the nearest possible civilization might be located tens of thousands of light-years away from us. The key conditions for the emergence of intelligence are considered to be an atmosphere rich in nitrogen and oxygen, as well as geological activity.
