Human Skeleton Quiz: What do you know about the bones of the body?
The human skeleton (the internal framework that includes bones and cartilage) evolved over millions of years. It consists of an axial skeleton consisting of the skull and vertebrae, and an appendicular skeleton including the shoulders, hips, arms, and legs. One of the main functions of the skeleton is to protect our soft internal organs, but […]
New hydrogen batteries can run four times cooler than before – meaning EV batteries are denser and last longer
Future electric vehicles could do away with lithium-ion batteries thanks to new advances in hydrogen energy storage at much lower temperatures than before. Researchers at Tokyo University of Science have created a hydrogen battery that uses magnesium hydride as the anode, hydrogen gas as the cathode, and a solid electrolyte with a crystalline structure. In […]

Connection between Cascadia and San Andreas earthquakes revealed 30 years after shipwreck uncovers important data
A new study suggests that the “Big One” of the Cascadia subduction zone in the Pacific Northwest could trigger similarly severe earthquakes on California’s San Andreas fault. The discovery is based on sediment taken from the ocean floor off Cape Mendocino, California, and off the coast of Oregon. It is at Cape Mendocino that California’s […]
AI reveals hidden ‘ring fault’ causing earthquakes at Italy’s Campi Flegrei volcano
An artificial intelligence (AI) model has revealed never-before-seen geological structures at Italy’s Campi Flegrei volcano, including an apparent “ring fault” that could trigger a magnitude 5 earthquake. So far in 2025, Campi Flegrei has experienced five earthquakes of magnitude 4 or higher, and the volcano has shown signs of instability since 2005. But most of […]
‘Planet Y’ theory suggests an Earth-sized world hidden in our solar system – and it could be much closer to us than ‘Planet Nine’
Astronomers believe they have discovered evidence of a previously unknown ninth planet lurking in a not-too-distant region of our solar system. The virtual world, dubbed “Planet Y,” is about the same size as Earth and could exist alongside another popular Planet Nine candidate, and if both are confirmed, it could bring the number of planets […]
Scientists identify new type 5 diabetes
Scientists have officially recognized a new type of diabetes, called type 5 diabetes, that is thought to affect 20 million to 25 million people worldwide. The disease is most common in Asia and Africa, where it was first identified more than 70 years ago but has been largely ignored until now. Traditionally, medical textbooks describe […]
‘Increasing attacks on water resources from multiple fronts’: scientists warn ‘day zero drought’ could occur by 2030
Unless emissions are reduced, almost three-quarters of the world’s drought-prone regions will be at risk of extreme water scarcity, known as a “day zero drought”, by 2100, and a third of these could be hit by 2030, according to a new study. Areas under threat include cities in the United States, the Mediterranean, and southern […]
Hidden ‘destined’ star revealed by James Webb Space Telescope could solve decades-old mystery
The James Webb Space Telescope (JWST) has revealed a hidden “doomed” star that could help solve huge astrophysical mysteries. The star is a massive red supergiant star, and JWST photographed it just before it exploded into a fiery supernova. In theory, most supernovae should be caused by massive red supergiants, but they are rarely observed. […]
The 2024 ice tsunami tore through Yukon Territory with enough force to rip through trees and riverbeds
Last December, a landslide struck a river in Canada’s Yukon Territory, causing a tsunami of slabs of ice to fly over two soccer fields, shearing trees in the process. Now, new research suggests that the damage caused by this “ice tsunami” was exacerbated by the destructive power of river ice. However, it was confined to […]
