In chaos theory, they say the infinitesimal flapping of a butterfly’s wings can hypothetically cascade into a fierce tornado. Now, scientists have demonstrated how some of the smallest creatures in the ocean could have the same outsized impact under the waves – with swarms of marine organisms inadvertently producing powerful currents that mix and churn

Not everyone is a weather enthusiast. But ever since I was old enough to start forming memories, I’ve been fascinated – even obsessed – with weather. For my seventh-grade science fair project, I predicted the weather for a week using nothing but homemade materials, including a simple barometer and hygrometer.   I was pretty darned

According to my understanding, all structures in the Universe, including the largest one, are magnetically ordered and centrally powered. The Milky Way follows this standard cosmic model. The astronomical objects and celestial bodies of our galaxy are connected to each other and ultimately to the extremely powerful magnetic field at its center. This is the
