New moonquake discovery could change NASA’s Moon plans

Scientists have discovered that moonquakes, not meteoroids, are responsible for shifting terrain near the Apollo 17 landing site. Their analysis points to a still-active fault that has been generating quakes for millions of years. While the danger to short missions is low, long-term lunar bases could face increasing risk. The…

Earth’s early oceans hid the secret rise of complex life

Scientists have discovered that complex life began evolving much earlier than traditional models suggested. Using an expanded molecular clock approach, the team showed that crucial cellular features emerged in ancient anoxic oceans long before oxygen became a major part of Earth’s atmosphere. Their results indicate that early complexity developed slowly…
