Turning light energy into heat to fight disease

An emerging technology involving particles that absorb light and turn it into localized heat sources shows great promise in several fields, including medicine. This heating must be carefully controlled however, and the ability to monitor temperature increases is crucial. Scientists report a method to measure these temperatures using terahertz radiation. The study involved gold nanorods in water in cuvettes, which were illuminated by a laser focused on a spot within the cuvette.

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
