Everyone knows that money doesn’t grow on trees, but how about inside tree leaves? Believe it or not, a new study finds it does. Well, sort of.
The Finding
The Nature Communications journal has published a report according to which the Eucalyptus (Myrtaceae sp.) tree’s leaves accumulate gold. Though gold and money are not quite identical (they used to be before the Bretton Woods Agreement was nixed), this finding allows a more effective search for underground gold deposits in the Australian outback.
More sensitive modern analytical techniques let you determine the gold concentration in a small sample of Eucalyptus tree leaves with ease. Just analyze enough Eucalyptus tree leaves from all prospective mining areas and, voila, you’ll know exactly where your new gold mine ought to be located.
Background
Of course, the knowledge that some plants may help you in finding mineral deposits is not new. Already in medieval times people recognized correlations of certain plants abundance with potential mine locations. There are many plants associated with specific minerals. That knowledge dates back hundreds or even thousands of years. For example, trace elements like zinc are important micro-nutrients for a variety of flowering plants. Naturally, you’ll find them in higher abundance in areas rich in zinc. The same is true for other micro-nutrients or trace elements like selenium, molybdenum and manganese. However, the association of the Eucalyptus tree with gold is new; at least to me.

But this health risk has been covered up ever since, denounces the Foundation. “Health authorities have been careful to exclude ILFN measurement and exposure limits from noise regulations”, said its CEO, Dr. Sarah Laurie. “To this date, they continue to deny any problem exists with ILFN emitted by wind turbines, ignoring complaints of victims and their right to be protected against known health hazards from industrial installations”.




“Global sea level has been rising as a result of global warming, but in 2010 and 2011, sea level actually fell by about a quarter of an inch. Scientists now say they know why: It has to do with extreme weather in Australia. The sea level drop coincided with some of the worst flooding in that continent’s history. Dozens of people died and torrents washed away houses and cars, forcing thousands from their homes. Some of those floodwaters simply ran back into the ocean, so they didn’t affect sea level. But a lot of that water was trapped on the Australian land mass. That’s because the continent has an odd geography.” writes Richard Harris [1] reporting on a work recently published by John Fasullo and others in the paper here commented [2].

In this view “greenhouse gases” function much like a blanket or winter clothing. 



As the journal Geophysical Research Letters (GRL) recently reported, such a claim is readily discredited. Peer-reviewed studies by experts in sea level rises (not climate ‘scientists’) suggest that no only have sea levels gone on rising irresistably for the last several thousand years, but that there is compelling new evidence pointing to the existance of multidecadal cycles in the historical mean sea level observations from many ocean basins.
