Investigating the magnetic properties of helium-3

In a joint experimental-theoretical study published in Nature, physicists at the Heidelberg Max Planck Institute for Nuclear Physics (MPIK), together with collaborators from RIKEN, Japan, investigated the magnetic properties of the isotope helium-3. For the first time, the electronic and nuclear g-factors of the 3He+ ion were measured directly with a relative precision of 10–10. The electron-nucleus magnetic interaction (zero-field hyperfine splitting) was measured with an accuracy improved by two orders of magnitude. The g-factor of the bare 3He nucleus was determined via an accurate calculation of the electronic shielding. The results constitute the first direct calibration for 3He nuclear magnetic resonance (NMR) probes.

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
