Zen stones naturally placed atop pedestals of ice: A phenomenon finally understood

Like a work of art enshrined in a museum, some stones end up on a pedestal of ice in nature, with no human intervention. This "Zen stone" phenomenon, named after the stacked stones in Japanese gardens, appears on the surface of frozen lakes, Lake Baikal (Russia) in particular. These structures result from the phenomenon of sublimation, which causes a body, in this case ice, to change from solid to gaseous form without the intermediary form of a liquid.

Seismic study reveals key reason why Patagonia is rising as glaciers melt

The icefields that stretch for hundreds of miles atop the Andes mountain range in Chile and Argentina are melting at some of the fastest rates on the planet. The ground that was beneath this ice is also shifting and rising as these glaciers disappear. Geologists have discovered a link between recent ice mass loss, rapid rock uplift and a gap between tectonic plates that underlie Patagonia. from Phys.org - latest science and technology news stories https://ift.tt/j1h2ds5

To confirm that semen is present, suspected stains are examined under a microscope to see if any sperm cells are visible. from Phys.org - latest science and technology news stories https://ift.tt/2XBwacB
