Why is the Solar System a disk?
One aspect of our solar system is that it is essentially a closed system. The stars are so widely separated that it would be rare for a stray asteroid or other object from beyond the Oort cloud to enter our solar system. This means that nearly all the rocky material orbiting the Sun now was also part of the solar system billions of years ago. This has a few consequences, one of which is the tendency for the solar system to lie in a plane.

A piece of prehistory.
It's a scientific axiom: big claims require extra-solid evidence. So when a geoscience professor dated an ancient crystal to 4.4 billion years ago, skeptics questioned the dating. Then, in 2013, researchers put the zircon inside an ultra-precise atom probe and got "data that answered the most serious of the challenges going back to 2001."

So cool.
The ability to teleport quantum information between diamond crystals that can also store it is a small but important step toward a quantum Internet.

Neutron gravity resonances and dark matter/energy
I'm reading up on a recent expeirment that used a neutron/gravity spectrometer to look for evidence of dark matter and dark energy.  I haven't got to review enough material to say something truly pithy here yet, but I thought I'd point you towards the stuff that's available.  First, here's a discussion of the experiment[1] from Texas A&M's own Dr. Schleich.  He's talked about this kind of thing before, (using neutrons for experiments involving gravity).  In fact, a little more than a year ago he gave a talk here on the KC interferometer and how it measured the acceleration due to gravity as opposed to the gravitational redshift as claimed by the authors[2].  His summary of the current set of experiments comes with the added bonus of a pointer to the open access version of the Physics Review Letters article on the experiment[3].  If you'd like to know how exactly you reflect a neutron from a wall without using coulombic forces which they don't particularly respond to anyway, (the answer has to do with Bragg diffraction), be sure to check out this article on an early test of a neutron interferometer.  Sadly, it's not open access, but again with the advice about local university libraries.

Some of the best customer service I've had in a long time. They had similar products to what I wanted but not exactly. So they looked up the number of a competitor, wrote it down, and offered to call.
