These blazing blue explosions may be born when a compact dead star slams into a Wolf-Rayet star

In a major advance, researchers at the Indian Institute of Science (IISc) have devised a method to grow high-quality 2D magnetic materials (2D-MMs) over centimeter-scale wafers. Earlier approaches in the field were limited to growing micrometer-sized flakes. This advance paves the way for their integration into next-generation electronics and spintronics materials used in hard drives and sensors.

I spent last summer wading through seagrass meadows across Northern Ireland, from the sheltered waters of Strangford Lough to the exposed coast at Waterfoot Bay. I was collecting seagrass leaves and testing them for nitrogen pollution. Every meadow I visited sits inside a marine protected area—a stretch of sea that's been given legal protection to safeguard the wildlife living there. And every single one was polluted beyond the limit for healthy seagrass.

Mercury is a small, rocky planet about which researchers know relatively little. Two missions, taking readings as they passed over the planet, have revealed that Mercury is covered by an iron-poor and sulfur-rich crust. It is also reduced, a chemical state in which the substances have gained electrons. In fact, it's the most reduced planet in the solar system.

In the heart of the Middle Atlas Mountains in central Morocco, a global team of paleontologists and geologists has discovered new remains of a very unusual dinosaur. It belonged to the group called ankylosaurs, plant eaters whose bodies were covered in bony plates.
