Moons, Stars and Sci-Fi Gadgets: GR Week in Review

Posted in Ghosts, Movies, Sci-Fi, Fantasy and Horror, Video, Weird News, Weird Science with tags , , , , , , , , , , , , , on June 29, 2009 by ghostradioworld


A somewhat slow week at GR.  But here’s a quick overview:

We looked at all the uses of sci-fi gadget, another sci-fi gadget that’s becoming a reality,  and a famous actor who’s known for playing a character fond of sci-fi gadgets.

We examined some water on a distant moon, saw a famous mystery solved by a space vehicle which cannot reach even a local moon,  and a movie with box office headed to the moon.

We heard of a star-filled movie headed for blu-ray, a star-shaped UFO over Brazil, and a no-stars movie review.

If there’s something you want us to cover let us know.  Either talk about it in the comment section or send an email to

It’s your blog just as much as it is ours.

Size Matters: First Nanoscale Gear!

How small is small enough?  Well, according to nanotechnology expects you can’t get small enough.  Hmm … we wonder what their teenage years were like.  ;)

From Science Daily:

Scientists from A*STAR’s Institute of Materials Research and Engineering (IMRE), led by Professor Christian Joachim,*  have scored a breakthrough in nanotechnology by becoming the first in the world to invent a molecular gear of the size of 1.2nm whose rotation can be deliberately controlled. This achievement marks a radical shift in the scientific progress of molecular machines and is published on 14 June 20009 in Nature Materials.

Said Prof Joachim, “Making a gear the size of a few atoms is one thing, but being able to deliberately control its motions and actions is something else altogether. What we’ve done at IMRE is to create a truly complete working gear that will be the fundamental piece in creating more complex molecular machines that are no bigger than a grain of sand.”

Prof Joachim and his team discovered that the way to successfully control the rotation of a single-molecule gear is via the optimization of molecular design, molecular manipulation and surface atomic chemistry. This was a breakthrough because before the team’s discovery, motions of molecular rotors and gears were random and typically consisted of a mix of rotation and lateral displacement.  The scientists at IMRE solved this scientific conundrum by proving that the rotation of the molecule-gear could be well-controlled by manipulating the electrical connection between the molecule and the tip of a Scanning Tunnelling Microscope while it was pinned on an atom axis.
