Thorny skates come in sizes of “snacks” and “party”: after a century of speculation, scientists know why now
Thorny skates don’t move much. According to Kneebone, individuals could remain in the 50-kilometer area for nine years. Credit: Florida Museum of Natural History, Christenglas When Jeff Neebone was a university student in 2002, his research included marine mysteries that have been baffling curious scientists for the past 20 years. The mystery involved thorny skates in the North Atlantic. In…

Northern Lights: How the Northern Lights Captivated People in the 18th Century
Credit: CC0 Public Domain Since May this year, the Northern Lights have been visible further south than usual over the UK, causing surprise and fascination. Social media is abuzz with images of skies glowing with green, pink and red light. We now know that these lights occur during magnetic storms. This is when charged subatomic particles, primarily electrons, collide with…
