There is a force all around us—unseen, unfelt, and yet profoundly influential. It guides the migration of birds across continents, whispers secrets to ancient rocks, and shields us from cosmic storms. This force is as mysterious as it is essential, shaping our world in ways that most of us never think about. Imagine a sailor centuries ago, staring at a compass that always points north. What guides ...[Read More]

What if a tsunami’s magnetic field could predict the height of the wave?

It’s been well established that tsunamis generate magnetic fields as they move seawater (which is conductive unlike freshwater) through the Earth’s magnetic field. Although researchers previously predicted that the tsunami’s magnetic field would arrive before a change in sea level, they lacked the means to simultaneously measure magnetics and sea level to confirm this phenomenon. Now, a new study ...[Read More]

Space weather is a ubiquitous, but little known, natural hazard. Though not as tangible as a volcanic eruption, storm or tsunami wave, space weather has the potenital to cause huge economic losses across the globe. In Europe alone, the interaction of solar wind with our planet’s magnetosphere, ionosphere and thermosphere, could lead to disrutions to space-based telecommunications, broadcasti ...[Read More]
