Apollo astronaut Harrison “Jack” Schmitt knows what the Artemis II crew was feeling when it rocketed into space earlier this month for a historic lunar flyby. Pure excitement and the potential for so much more. Schmitt is one of the four people still alive who walked on the moon during the Apollo missions more than 50 years ago. As the first scientist to set foot there, he spent three days with fellow astronaut Eugene Cernan collecting rock and soil samples. Schmitt, now 90, spoke to The Associated Press about the importance of having a lunar base, the potential for tapping isotopes on the moon for energy production and whether we're alone in the universe.

Scientists have discovered fossils in China that reveal a crucial transition from simple to complex life on Earth. These fossils, dating back 539 million years, show complex animals living three-dimensional lives, millions of years earlier than previously thought. This challenges the belief that such complexity only emerged during the Cambrian explosion. Experts say this finding provides a glimpse into how modern animal life developed. The study, published in Science, also helps settle the "rocks versus clocks" debate in paleontology, aligning fossil evidence with genetic data. Researchers are now exploring how and why this rapid evolution occurred.
