Climate change could lead to more iron fertilization
Sea creatures, whether large or small, need nutrients. The supply mechanism delivering these nutrients is very different in different parts of the ocean. There are nutrient-rich coastal areas, but also very nutrient-poor regions in the open ocean.
Icebergs as a source of nutrients

As far as hypothetical space megastructures go, the stellar engine is one of our favorites — a gigantic contraption built with the purpose of transporting our solar system somewhere else, if we ever need to move to a different cosmic neighborhood.
Radical new 'stellar engine' could move entire solar system
From a physics and chemistry standpoint, fire is an incredibly complicated phenomenon — so much so that 19th century physicist Michael Faraday built an entire series of six lectures around the flame of a single candle at the Royal Institution in 1848. Fuel, heat, and oxygen, combined under the right conditions, ignite into a sustained chemical reaction: Fire.
Scientists model dynamic feedback loop that fuels the spread of wildfires
The star, Betelgeuse, is suddenly dimming. It may be a sign, astronomers say, that the star is about to explode. Another possibility is the red supergiant may just be going through a phase.
Scientists think giant red star may be about to explode
During the past years, artificial intelligence (AI) — the capability of a machine to mimic human behavior — has become a key player in high-techs like drug development projects.
