The peatland 'nurseries' of Peru give new insights for conservation

British scientists have launched a crew of microscopic worms to the International Space Station in a pioneering experiment that could help unlock the secrets of long-duration space travel—and support ambitions to reach the moon and beyond.

The successful Artemis II trip around the moon was a historic achievement—the first crewed lunar fly-by in more than 50 years, and the greatest distance yet traveled by humans from our "pale blue dot."

Acoustic metamaterials are a fast-evolving family of materials which manipulate sound waves in ever more advanced ways. Now, a team led by Changqing Xu at Nanjing Normal University in China has engineered an acoustic metamaterial, a "ghost tunnel": a structure which acts as a near-perfect waveguide for sound entering through its ends, while being essentially invisible to waves incident on its sides. The results, published in Physical Review Letters, could open new avenues for manipulating sound
