A strike-slip fault and glaciers created Scotland's unusually straight Great Glen

During glacier surging, these bodies of ice can move over half a football field a day

The movement of these glaciers, which repeatedly speed up and advance for months or years after stalling or moving backward for a time, results from melting ice that reduces friction between them and the ground, allowing them to slide more quickly. Scientists note that this effect is becoming more frequent due to climate change.

The story behind the little Scottish village in the Italian Alps

High in the Italian Alps is Gurro, a small village with a distinct Scottish flair that can be found in its food, clothing, language, and music. At first glance, it may seem like a curiosity, but, as one resident explains in this short video documentary, there's a perfectly reasonable explanation for how an Italian town became known as a Scottish hamlet.

Cooling lava naturally creates hexagonal cracks to evenly relieve stress

When lava cools and turns into rock, it contracts and builds up tension, particularly when held in place by the surrounding landscape. Just as drying mud cracks, initial cracks in the rock are random, but quickly organize into a hexagonal pattern, which scientists consider the most space-efficient shape.

Great circles provide the shortest path between two points on a sphere

On Earth, a great circle is formed by slicing through the planet, such that one cuts through the center alongside the two locations from which the shortest distance needs to be found. The resulting arc along the Earth's surface is responsible for curved routes on flight maps, rather than straight trajectories.

How a Scottish island became awash in forever chemicals—and what it means for other coastal areas

Utility data from 2024 indicates that Fair Isle, Britain's most remote inhabited island, has Scotland's highest level of toxic PFAS—forever chemicals—in its public drinking water. The level is still below Scotland's safety threshold, yet the high levels have confounded scientists and communities because there are no obvious industrial sources on the island. An investigation by The Guardian suggests those chemicals are arriving from thousands of miles away via seaspray and foam. PFAS are persistent pollutants that are chemically attracted to the interface between water and air—meaning there will likely be more of them in seafoam than there may be in the seawater itself.

Wales has had a massive influence on fantasy music, movies and books

Many of "The Lord of the Rings" settings and languages are rooted in the country's landscape and dialect. Studio Ghibli icon Hayao Miyazaki was inspired by Wales' countryside. Rock band Fleetwood Mac used Welsh myths as a basis for songs.

An investigation suggests a Scottish island became awash in forever chemicals via seafoam and seaspray—raising questions about what that means for the safety of other coastal areas.

An exploration of what makes Olympic curling so difficult and strange

The sport is often maligned for its oddity, but this impassioned video argues it's one of the more impressive (and good-natured) sports in the Olympics. Sometimes labeled "chess on ice," curling at the Olympics uses 44-pound, 60-million-year-old granite stones all extracted from the same Scottish island.

Spikes of light around stars are artifacts of light bending around the mirror supports

Through diffraction, electromagnetic waves can bend around obstacles, as observed in the silver linings at the edges of clouds, where light should be blocked. Within reflecting telescopes, starlight diffracts around struts—beams holding a secondary mirror in place—and spreads perpendicular to them, creating pairs of spikes.

Multiple sclerosis means 'many scars'

That's a reference to the scarring or lesions that occur in the brain, spinal cord, and elsewhere whenever the immune system has a flare-up. The immune system attacks the myelin because it incorrectly responds as if it's a threat, damaging the body's ability to transmit electrical signals effectively from areas of the body to the brain.
