Mosquitoes push northern limits with time-capsule eggs to survive winters

When the Asian tiger mosquito (Aedes albopictus) arrived in the United States in the 1980s, it took the invasive blood-sucker only one year to spread from Houston to St. Louis. New research from Washington University in St. Louis shows that the mosquitoes at the northern limit of their current range are successfully using time-capsule-like eggs to survive conditions that are colder than those in its native territory.

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
