Key Facts Climate & Environment Insects Vanishing Even in Pristine Habitats Mounting evidence indicates the insect biodiversity crisis has reached even untouched ecosystems. A long-term study in the Colorado Rockies found flying insect abundance has collapsed by ~72% over 20 years in a subalpine meadow with minimal human impact sciencedaily.com. Higher summer temperatures were tightly correlated with the decline, implicating climate change rather than local land use. “Insects have a unique…vulnerability to environmental change,” warns biologist Keith Sockman, who led the study sciencedaily.com. He notes that mountain ecosystems host many endemic species which “may be in jeopardy if the declines shown

The Solar System’s Invisible Boundary – What and Where Is It? When we gaze up at the night sky, it’s easy to imagine the solar system simply fading into the depths of space. In reality, our solar system ends at a distinct, albeit invisible, boundary.

Scientists call this frontier the heliopause, and understanding it is key to answering the age-old question: Where does the solar system end? At the heart

Key Facts Space Exploration: 6,000 New Worlds & Starship Progress In a milestone for astronomy, NASA confirmed the 6,000th exoplanet – planets orbiting other stars – in its records this week. The official tally of alien worlds crossed the 6k mark after only ~30 years of exoplanet hunting, reflecting an exponential discovery rate space.com. “We’re entering the next great chapter of exploration – worlds beyond our imagination,” a NASA video proclaimed space.com. NASA noted that because new planets are added on a rolling basis by scientists worldwide, “no single planet is considered the 6,000th entry… There are more than 8,000
