Scientists are using satellite data to monitor tree health near volcanoes. Trees absorb volcanic carbon dioxide, which makes them greener. NASA's AVUELO project and other satellites track these changes. This helps detect early signs of volcanic activity. The goal is to improve volcano early warning systems, especially in remote areas. Ground observations are crucial for verifying satellite data.
Scientists have identified *Ikaria wariootia*, a tiny wormlike creature from 555 million years ago, as the earliest known bilaterian. This discovery from South Australia reveals the origin of bilateral body structure, a key feature in most animals today. The fossil's characteristics and burrowing behavior provide insights into early animal evolution and locomotion.
The deep ocean, covering most of Earth, remains largely unexplored, with only 0.001% visually studied. It regulates climate, harbors unique ecosystems, and holds potential resources. However, human activities like climate change, pollution, and overfishing threaten this vital environment before its true value is understood, necessitating urgent conservation efforts and sustainable practices.
Group Captain Shubhanshu Shukla is preparing for the Axiom-4 mission to the ISS, now launching no sooner than June 8, 2025. This joint ISRO, NASA, and ESA mission marks a significant step for India's space program.
