Tides can vary by almost a meter across a single bay, four decades of satellite images reveal and more — today's certification signal.
Scientists continue to uncover hidden patterns and valuable data in our planet and beyond, shedding light on complex phenomena that shape our understanding of the world. Researchers analyzing four decades of satellite images have made a surprising discovery about tidal variations within bays, finding that tides can differ by almost a meter across a single bay. This finding highlights the intricate dynamics at play in our oceans. Meanwhile, studies of extraterrestrial materials, such as meteorite dust and space rocks, are providing new insights into the formation of our solar system, including the magnetism that may have helped form the sun and the processes that turn space rocks into meteorites.
Closer to home, scientists are working to mitigate the impact of human activities on the environment. A new methane sensor has shown promise in detecting cow burps in real-time, matching the accuracy of industry monitors in early field tests. This innovation could help reduce greenhouse gas emissions from agriculture. In another breakthrough, researchers have identified bacteria from ancestral wheat microbiomes that can protect plants against root rot fungus, offering a potential solution for sustainable agriculture. Additionally, advances in materials science have led to the discovery that ball milling can enhance the antiviral activity of inexpensive inorganic materials, opening up new possibilities for public health applications.
