Melody of an Alpine summit falling apart

The summit of the 2592 meters high Hochvogel is sliced by dangerous fracture which continues to open. It is difficult to judge when the summit might crack. Researchers are developing a new monitoring method. Seismic sensors measure the summit's natural vibration. The pitch of the mountain changes depending on the tension in the rock allowing unique conclusions about the development of a landslide.

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

New method to detect and visualize sperm cells recovered from forensic evidence

One of the most valuable forms of forensic evidence in cases of male-perpetrated sexual assault is the presence of semen, either in the form of stains left behind on items or on swabs collected from victims after an offense. 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
