Last year, scientists at the Technical University of Denmark (DTU) got in a festive mood and created "the world's thinnest Christmas tree." This time, they've produced what they claim is the world's smallest record, complete with a Christmas tune engraved into it.

Although we've been hearing about stronger forms of concrete, one of the keys to making concrete last longer is to keep water from seeping into it. A new surface sealant could help, as it makes existing concrete 75 percent more water-repellent.

Because nanoscale objects are so incredibly small, they don't reflect enough light for even the best microscopes to discern details such as their color. A new lighting system, however, addresses that problem by acting as a tiny spotlight.

No matter how hard we may try, we can't really tell if we've got bad breath – and asking someone else to sniff our breath for us can be awkward. It's now possible that before too long, however, a portable "thumb-size" device could let us know.

The Japanese folding paper art form of kirigami has a lot of potential for engineering. Scientists have taken this technique down to the nanoscale for the first time, opening up new possibilities in applications ranging from robotics to aerospace.

Impressive new work has demonstrated a potential way to restore vision in those suffering from degenerative diseases of the retina. A single injection of nanoparticles was found to create a working artificial retina, restoring vision to blind rats.
-
Researchers at Empa and EPFL have created one of the smallest motors ever made. It’s composed of just 16 atoms, and at that tiny size it seems to function right on the boundary between classical physics and the spooky quantum realm.
-
Nanofibers have found use in numerous applications, ranging from lightweight car parts to high-strength materials. Now, thanks to a new understanding of a certain group of spiders, they may soon be easier to work with.
