Robotic manipulation demo(s)
Very nerdy, fun to watch... Makes you appreciate the speed of robotic manipulators.
They can go much faster by the way... For example:

42! [Just a map of the universe]
Not coming to your car GPS anytime soon, but still a nice map. The 'map' of our universe is getting a little bit more detailed.
The dot on the picture is our galaxy, potentially marked as 'mostly harmless.'

What is Code?
This (long) article from Bloomberg Business week is a bit old, but still pretty good introduction for newbies, non-technical persons, and many others.

Pure magic: Direct counterfactual communication via quantum Zeno effect
Not really, it's just science (or physics)...
PNAS (Proceedings of the National Academy of Sciences of the United States of America) published a manuscript titled "Direct counterfactual communication via quantum Zeno effect" by Cao et al.
The article's significance, submitted in August 2016, is given as:
"Recent theoretical studies have shown that quantum mechanics allows counterfactual communication, even without actual transmission of physical particles, which raised a heated debate on its interpretation. Although several papers have been published on the theoretical aspects of the subject, a faithful experimental demonstration is missing. Here, by using the quantum Zeno effect and a single-photon source, direct communication without carrier particle transmission is implemented successfully. We experimentally demonstrate the feasibility of direct counterfactual communication with the current technique. The results of our work can help deepen the understanding of quantum mechanics. Furthermore, our experimental scheme is applicable to other quantum technologies, such as imaging and state preparation."

Speck of dust... Mostly harmless...
Space.com posted a few new images from Cassini probe that highlight our relative size/position/importance in the universe.
Note that these pictures are taken inside the solar system, basically close ups. Have you seen the moon, next to the earth?
Visit the first two links below for more eye-pooping images.
