Ocean salinities show an intensified water cycle
The stronger water cycle means arid regions have become drier and high rainfall regions wetter as atmospheric temperature increases.
The study, co-authored by CSIRO scientists Paul Durack and Dr Susan Wijffels, shows the surface ocean beneath rainfall-dominated regions has freshened, whereas ocean regions dominated by evaporation are saltier. The paper also confirms that surface warming of the world’s oceans over the past 50 years has penetrated into the oceans’ interior changing deep-ocean salinity patterns.
`This is further confirmation from the global ocean that the Earth’s water cycle ... |

Modified plant clears up deadly water toxin
Plants may be a useful tool in clearing water of harmful toxins produced by blue-green algae, new research indicates.
Some blue-green algae (cyanobacteria) — which grow in warm, nutrient-rich waters — produce toxins that can severely damage the liver or nervous system. The effects of the toxins range from a mild illness to rapid death. They can remain in water supplies after the algae have been killed.
A team at St George`s Medical School, part of the UK-based University of London, has modified tobacco plants to secrete antibodies from the roots that then bind to microcystin-LR — the ... |
