Google is doing its part to restore several lost pieces of art that got destroyed during WW2. In order to restore the art, the search engine giant is using artificial intelligence, according to Mashable. It is said that these pieces were part of the loot collected by the German army, which was stored at a castle in Austria. During the last few months of the war, this castle played host to a still-unconfirmed number of artworks by the Austrian artist Gustav Klimt, with the most valuable ones being part of a series called the "Faculty Paintings." However, the Faculty Paintings have been largely destroyed, and only black and white photographs of them exist.

For Google, the massive network of data centers that powers the web giant's operations run up a similarly massive energy tab. The company has been improving server farm efficiency for years, but it recently adopted a novel technique for trimming usage: letting the robots take control. In particular, Google is giving the reins to an artificial intelligence system developed by its subsidiary DeepMind. The AI overlord succeeded in shaving several percentage points off of data center energy consumption, Bloomberg reported. This led to a 15 percent improvement in power-usage efficiency, the metric of how much power goes to the actual computing as opposed to auxiliary services at the data centers.
