I concur. And it is precisely this fact, which requires us to stand in solidarity with all those marching to demand their inalienable human rights.

Likely, some of the troops got overheated, and just decided to fire. If al-Khalifa had intended to put down the demonstrations by the barrel of a gun, the efforts would be more directed and persistent. That's the danger of having the guns out there in the first place. I am less surprised by the people getting shot in this case, than the paucity of those who have been shot in Egypt.

Only the protagonist was not as nice as tomqvaxy...
This story reminds of a morality play I once read.
What you wear can have unintended consequences.

I'm simply entranced by the fact that the name is Sud Sudan in French.
They must use this for a classic African Polyrhythm style national anthem.

Here's a pretty good 'state of the art' summary on what we know about gas giant planets at the present. It's in .pdf format, and really a fairly easy read, if you want something to refer people to. Looks like only about 38 pages. See particularly the discussion of the gas giant/brown dwarf continuum, and their relative thermal output (which of course relates to the infrared).

It is cutting edge planetary astrophysics. So it is pretty cool.
And... Yeah. It truncated it.

The article on the D/H fusion of low mass brown dwarf stars was a different one from 2002 I think. I'll send that after I go back and find it.

I'd rather have a jazzy mass ejection, than a new Maunder Minimum, any day.

The 13 Mass Jupiter(Mj) lower limit, is a generalization of the minimum mass required for a deuterium fusion reaction that is strong enough to hold the architecture of the sphere intact by the thermal pressure of the reaction itself, given a D/H ratio similar to that of the Sun. If the deuterium to hydrogen (D/H) ratio is larger, then the mass can be smaller. Additionally, the percent of the hydrogen core that is metallic affects the minimum mass required as well. My understanding, is that a persistent thermonuclear reaction could be possible at a lower temperature and pressure (a sort of 'cold fusion', but not really cold in any terrestrial sense) in a metallic hydrogen core that is sufficiently enriched with deuterium. The article I gave you, parses out the theoretical limits of persistent deuterium fusion in the Jovian core. A gas giant of 4-5 Mj would need even less deuterium enrichment compared to the Sun's composition to maintain fusion. Interestingly, the primary radiation energy of very low output brown dwarf stars, would be in the near infrared, as I pointed out previously. So using an orbiting, cooled infrared telescope, we would likely be able to see it. Thus possibly making that approach more precise than gravimetric location methods. Thanks for the chance to talk about this stuff. You definitely have an eye for the interesting breaking science news!
