The gold in objects from Troy, Poliochni (a settlement on the island of Lemnos which lies roughly 60 kilometers away from Troy), and Ur in Mesopotamia have the same geographic origin and were traded over great distances.

Imaging human cells: New method enables clear, precise look inside

It's why Jaws swam out of sight for more than an hour, and it hints at the glamor of giftwrap. In movie theaters, living rooms, and even labs, the thrill of the unseen can be counted on to keep us guessing. But when it comes ...

How photoelectrodes change in contact with water

Photoelectrodes based on BiVO4 are considered top candidates for solar hydrogen production. But what exactly happens when they come into contact with water molecules? A study in the Journal of the American Chemical Society ...

2400 new eyes on the sky to see cosmic rainbows

The Subaru Telescope successfully demonstrated engineering first light with a new instrument that will use about 2400 fiberoptic cables to capture the light from heavenly objects. Full operation is scheduled to start around ...
