New study finds black spruce trees struggling to regenerate amid more frequent arctic fires

A new study, published in the Proceedings of the National Academy of Sciences (PNAS), finds that black spruce trees—a key species on the boreal landscape for millennia—are losing their resilience and capacity to regenerate in the face of warming temperatures and increasingly frequent Arctic wildfires. A continuation of this trend could result in a landscape-wide ecological shift that would have a complex and rippling impact on the region, including an acceleration in permafrost thaw, and a loss of valuable biodiversity.

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
