A clearer look at critical materials, thanks to refrigerator magnets

With an advanced technology known as angle-resolved photoemission spectroscopy (ARPES), scientists are able to map out a material's electron energy-momentum relationship, which encodes the material's electrical, optical, magnetic and thermal properties like an electronic DNA. But the technology has its limitations; it doesn't work well under a magnetic field. This is a major drawback for scientists who want to study materials that are deployed under or even actuated by magnetic fields.

Mapping how Arctic groundwater will respond to thawing permafrost

Dalhousie researchers have revealed how Arctic aquifers—permeable layers of the ground that store and transmit water to rivers, lakes and terrestrial ecosystems—behave today and how these vital resources will change with warming temperatures and sea-level rise.

Ancient Alaskan site may help explain how the first people arrived in North America

New evidence has emerged that sheds light on the possible first people to populate the Americas. Dating of stone and ivory tools found at an archaeological site in Alaska suggests that these early pioneers traveled through the region on their way to the continent about 14,000 years ago.
