Synchronizing things… That are already in sync…
Scientists have set up the world's most precise 'metronome' for a kilometer-wide network. The timing system synchronizes a 4.7-kilometer-long laser-microwave network with 950 attoseconds precision. An attosecond is a millionth of a millionth of a millionth of a second. (1) Impressive. Or so it seems. Because the problem is not synchronization per se. Everything is…

Ghost images. Glows. At the corners of the universe…
A team of physicists at The Australian National University (ANU) has used a technique known as 'ghost imaging' to create an image of an object from atoms that never interact with it. Lead researcher Associate Professor Andrew Truscott from the ANU Research School of Physics and Engineering (RSPE) said the experiment relied on correlated pairs…

Time crystals. In a timeless world…
It may sound like science fiction, but it’s not: Scientists have created the first time crystal, using a chain of ions. Just as a standard crystal repeats in a regular spatial pattern, a time crystal repeats in time, returning to a similar configuration at regular intervals. (1) Crystals developing in time. Over and over again.…

Dinosaurs. Νείκος. Φιλότης.
A new publication on the bird-like dinosaur Avimimus, from the late-Cretaceous suggests they were gregarious, social animals - evidence that flies in the face of the long-held mysticism surrounding dinosaurs as solo creatures. "The common mythology of dinosaurs depicts solitary, vicious monsters running around eating everything," explains Gregory Funston, PhD student and Vanier scholar at…

Ocean. Rogue waves. Darkness.
Rogue waves are extremely high ocean waves that exceed the significant wave height by more than a factor of 2. Extreme waves are also very rare; less than one in 100,000 waves exceeds the rogue wave criterion. While their existence was long disputed throughout the 1990s, thousands of rogue waves have been recorded on oil…
