The more moving parts a machine has, the more likely it is to eventually fail. It’s an especially problematic rule of thumb for aircraft given the fact that a mechanical failure during a flight can be catastrophic. To help remedy this, a British aerospace company recently tested a unique plane that replaces its wing’s adjustable ailerons with powerful blasts of air to steer the craft.

On November 11, 2018, a deep rumble ricocheted around the world, one that humans couldn’t feel but that registered quite clearly on seismometers. A new pre-print paper about the event is now suggesting that it was caused by the largest offshore volcanic event in recorded history.
It’s been around 100,000 years since California’s Long Valley supervolcano experienced a major eruption, but this supposedly dormant caldera has been acting a bit strangely over the past four decades. New research suggests 1000km3 of magma still exists within this supervolcano, but thankfully, a major eruption remains unlikely.
At the end of the Cretaceous era, a large meteorite ploughed into what is now Mexico's Yucatan Peninsula. The collision set off a chain reaction of environmental calamities that likely contributed to the demise of the dinosaurs. New research is now adding to the list of ensuing catastrophes, suggesting the collision cracked our planet's seafloor like an egg, forcing magma to pour out along the ocean's tectonic ridges.
Video: Fire bubbles! That's what happens when burning hot liquid magma hits water. National Geographic writes that, "Scientists are trying to determine the potential dangerous effects of introducing water into a pressurised pocket of magma underground."
Good old geothermal plants generate power using water heated by hot rocks deep underground. But what if we could get energy directly from the seething magma down below? In Iceland, an accidental discovery let scientists actually stick a pipe into magma to test this idea -- and the results of their experiment has just been published.
