It’s a sunny Sunday in Chengdu, a sprawling city of 10.4 millionin China’s southwestern hinterland, and that can meanonly one thing: shopping. The gleaming new indoor malls that line every downtown boulevard teem with young and old, laughing, talking, walking arm in arm, checking out the latest from Tommy Hilfiger, Disney, and Esprit. Along Tai Sheng East Road, the scene really heats up. Once a sleepy street lined with hardware and electrical-supply shops, it’s now the city’s bustling cell phone district. In store after store, block after block, thousands of cellphone models from more than a hundred domestic and foreign brands beckon from store windows. Amid the crowds, the cacophony of ring tones, and the sales clerks hawking new calling plans, it’s tough to move or think. No wonder the largest cellphone maker in the world, Finland’s Nokia Corp., in Espoo, recently disclosed that China will soon overtake the United States as its top market.

The next time humans land on the moon, they intend to stay awhile. For the Artemis program, NASA and its collaborators want to build a sustained presence on the moon, which includes setting up a base where astronauts can live and work.

One of the crucial elements for a functioning lunar base is a power supply. Sandia National Laboratories, a research and development lab that specializes in building microgrids for military bases, is teaming up with NASA to design one that will work on the moon.

Trilobite-Inspired Camera Boasts Huge Depth of Field

New camera relies on “metalenses” that could be fabricated using a standard CMOS foundry

Inspired by the eyes of extinct trilobites, researchers have created a miniature camera with a record-setting depth of field—the distance over which a camera can produce sharp images in a single photo. Their new study reveals that with the aid of artificial intelligence, their device can simultaneously image objects as near as 3 centimeters and as far away as 1.7 kilometers.

Five hundred million years ago, the oceans teemed with horseshoe-crab-like trilobites. Among the most successful of all early animals, these armored invertebrates lived on Earth for roughly 270 million years before going extinct.
