Why Is This 112-Year-Old Church Floating in the Air?
Art installation? Trick photography? Nope, just a little restoration project going on at Utah’s Provo Temple, which was badly damaged in a fire in 2010. Thankfully, the Church of Jesus Christ of Latter-day Saints (LDS) is salvaging the 112-year-old building with a little architectural levitation.

The World's Fastest Wi-Fi Puts Your Sluggish Router to Shame
For the most part, we’re all happy if we can get Internet that’s fast enough to stream some HD video. But faster is always better, and a new, world-record setting network developed in Germany is so blazing fast you wouldn’t know what to do with it. It can deliver multiple HD films in a second.

This Table Designs Itself With a Corrosive Chemical Dance Party
There are all kinds of ways to design a table, but most of them don’t include resonant frequencies or specially-designed abrasive enzymes, much less both. Bonus Table 571 isn’t most tables though, and that’s exactly how it gets its very specific pattern.

That warped sense of nationalism
Either the Philippines is unified rooting for a Filipino taking part in an international contest or one held in another country or it’s unified against a fellow(wo)man running for a national post.

The acoustic signatures of many animals contain features we humans cannot appreciate, given the limited range of frequencies we can hear. In fluid dynamics and many other fields, scientists and engineers have to find ways to analyze and decompose time-series data—like acoustic pressure signals—into useful quantities. Mark Fischer uses one tool for such analysis, a wavelet transform, to turn the calls of whales, birds, and insects into the colorful snapshots seen here. Wavelet transforms are somewhat similar to Fourier transforms but represent a signal with a series of wavelets rather than sinusoids. They’re also widely used for data compression. (Image credits: M.
