Museums are regarded as places of inspiration and cultural experience—boredom is not the first thing that springs to mind. However, an international team of researchers led by Thomas Götz from the University of Vienna has now, for the first time, systematically investigated how
Long before modern astronomy, humans looked to the stars and were astounded by what they saw. Even by the most ancient reckoning, the night sky offered enough to inspire awe and wonder, make us feel insignificant, fire our imaginations and foster hope and a sense of connection.
Using a new technique, a research group led by Osaka Metropolitan University (OMU) has substantially increased the range of plastics that can be degraded naturally. The study is published in the journal Macromolecules.
Located farther away from Earth than Pluto, the object was hidden in the light of the Milky Way’s stars
When people think about making a good impression at work, the focus usually turns inward. How do I present myself? How do I demonstrate my value? How do I make sure others see me as capable, confident and influential?
Over the past 50 years, Canadian English has become more uniform across regions and has adopted many American terms and pronunciations, while the use of Canadian spellings has gained in popularity. These are the key results of a large-scale study by McGill researchers to update
What happens to our memories when we learn disturbing news about a beloved artist? New research from the University of South Florida finds that after a scandal, the brain tricks us: it reconciles a fallen artist with their adored art by rewriting our memories in two completely
As cities grow in population, they grow proportionally in terms of infrastructure—new buildings, paved streets and parking lots. Or so says conventional wisdom. However, a new study by a team of New York University researchers dispels this thinking.
Antarctica's glaciers were changing long before satellites, weather stations or cameras captured their transformations, and they left behind clues. Along Marguerite Bay on the western Antarctic Peninsula, ridges of rocks and debris mark former glacier margins. For decades,
Since the production of graphene in 2004, two-dimensional materials have been sparking scientific and technological interest. As they are only a few atomic layers thick, or even just a single atomic layer, they can exhibit special electronic, magnetic or chemical
