The sun has been acting up, and that might mean a special light show for some folks in the Carolinas. A big solar flare sent a bunch of charged particles our way. These particles could mess with Earth's magnetic field and create the northern lights, also known as the aurora borealis. This is a big d
Lying down for a long time can mess with how blood flows in your brain. This is what scientists found out when they studied 36 healthy adults who spent 90 days in a head-down bed rest position. They used a special kind of MRI called pseudo-continuous arterial spin labeling (pCASL) to track changes i
Deep in a cave in Morocco, old bones tell a story. They show where our species might have started. These bones are over 773, 000 years old. They were found in layers of earth that formed when Earth's magnetic field flipped. This flip happened a long time ago. The north pole was near the south pole.
The Sun, our closest star, has been putting on quite a show lately. In 2024, scientists got a front-row seat to one of the most active solar regions in decades. This wasn't just any solar activity; it was a massive, complex magnetic structure that caused some of the strongest solar storms in years.
Something weird is happening way up in the sky. Earth's magnetic field is acting strange. It's not following the usual rules. Normally, big solar storms cause this kind of fuss. But this time, the sun isn't to blame. Scientists are scratching their heads. The effects are real, though. Bright lights
Scientists have found a new way to read tiny magnets using light. These magnets are so small that they are made of just one molecule. The cool part is that this method works with light that is not visible to our eyes, but it is the same light used in fiber optic cables for the internet. The magnets
Blood pressure is a big deal when it comes to heart health. It's not just about what's happening right now, but also what's been going on for years. High blood pressure over time can lead to serious heart issues. Researchers wanted to see how long-term blood pressure affects the heart's ability to g
Graphene, a single layer of carbon atoms, has been a hot topic in science for years. But now, researchers are looking at stacked layers of graphene, twisted at special angles, called magic angles. These twisted layers can show weird and interesting behaviors, like becoming insulators or even superco
Quantum materials are fascinating because they can change their electronic and magnetic behaviors when exposed to magnetic fields. However, studying these changes has been tough. The main issue is that magnetic fields mess up the paths of electrons ejected from these materials during experiments. A
Uranus and Neptune may not be the icy worlds we once thought. Recent research from the University of Zurich suggests these planets might be more rocky than previously believed. This challenges the traditional classification of planets in our solar system. Typically, planets are grouped into three t
