Recent breakthroughs suggest that hydrogen reservoirs are buried in countless regions of the world, including at least 30 U.S. states. Finding such reservoirs could help accelerate a global energy transition, but until now, geologists only had a piecemeal understanding of how large hydrogen accumulations form — and where to find them. “The game of the … Read more
Digestive gas gets the best of everyone sooner or later, often in the form of a burp. Burping is how the body clears excess gas from the upper digestive tract, which would otherwise result in extremely uncomfortable pressure in your stomach and esophagus. Or at least that’s how it works on Earth. In space, everything … Read more
Constant gusts of particles from the sun may be creating water molecules on the moon, a new NASA-led experiment hints. Scientists have detected traces of water molecules — as well as hydroxyl (OH) molecules, a component of water — on the surface of the moon through multiple space missions. The source of this water has … Read more
Nearly three fourths of Earth is covered by oceans, making the planet look like a pale blue dot from space. But Japanese researchers have made a compelling case that Earth’s oceans were once green, in a study published in Nature. The reason Earth’s oceans may have looked different in the ancient past is to do … Read more
Imagine you’re eating dinner. You try to pour some ranch dressing onto your plate to dip your veggies into. You tip the container upside down, but nothing comes out. Seems like a solid. So you shake the bottle up and down, and a big blob of dressing plops out and hits your plate. Seems like … Read more
We may have been wrong about how Mars got its characteristic red hue, a new study reveals. The Red Planet owes its ruddy complexion to rusted iron minerals, dispersed across billions of years by winds, throughout the planet’s dust. Past spacecraft observations of Martian dust led scientists to believe that this rust emerged in dry … Read more
Chinese astronauts have just created rocket fuel and oxygen in space using a new type of “artificial photosynthesis.” The breakthrough technology, which used fairly basic equipment and minimal energy, could one day be put to use on China’s proposed moon base, which is scheduled to be completed within a decade. The new experiments were carried … Read more
It may take less than 1,000 years for an advanced alien civilization to destroy its own planet with climate change, even if it relies solely on renewable energy, a new model suggests. When astrophysicists simulated the rise and fall of alien civilizations, they found that, if a civilization were to experience exponential technological growth and … Read more
Certain bacteria can degrade the strong bonds that give “forever chemicals” their long shelf life, and this hints at potential low-cost treatments that could cleanse water of concerning PFAS. PFAS, or perfluoroalkyl and polyfluoroalkyl substances, are human-made compounds found in many products. They contain strong chemical bonds that do not easily break down, making them … Read more
Psilocybin, the compound that makes magic mushrooms trippy, works its magic by desynchronizing the brain network responsible for a person’s sense of self, new research finds. Psilocybin warps people’s sense of time and space, as well as shifts their feelings of connection to the world around them. While most of these subjective effects wane pretty … Read more
