North Korea says it has authorized plans for nuclear strikes against the United States.

Bad: North Korea says it has authorized plans for a nuclear strike against the United States.

But, while Pyongyang has successfully carried out test nuclear detonations, most experts think it is not yet capable of mounting a device on a ballistic missile capable of striking US bases or territory. Mounting tension in the region could however trigger incidents on the tense and heavily-militarised border between North and South Korea. There was no immediate American reaction to the North’s latest statement, but US Defense Secretary Chuck Hagel said Pyongyang represented a “real and clear danger” to the United States and to its allies South Korea and Japan.

Right now North Korea almost certainly cannot hit the U.S. with an ICBM. However, South Korea and Japan are very very very exposed.

“The SLS program should be canceled now to free up approximately $10 billion programmed for this decade.”

“The SLS program should be canceled now to free up approximately $10 billion programmed for this decade.”

I’m both glad and not surprised that some heavy hitters are beginning to say this. As I noted last year, as the commercial space program begins to show success the politics will increasingly favor it over the very expensive and not very productive NASA-built Space Launch System.

Be prepared for SLS to steadily lose political support in the coming years.

The Alpha Magnetic Spectrometer on ISS has detected a surplus of positrons, anti-matter electrons, that physicists believe are caused by the existence of dark matter.

The lead scientist of the experiment also emphasized that dark matter is not the only possible explanation, and that “The detailed interpretation of our data probably will have many theories.”

An audit of California’s fiscal state has found it to be $127 billion in the red.

The day of reckoning looms: An audit of California’s fiscal state has found it to be $127 billion in the red.

Were California’s state government a business, it would be a candidate for insolvency with a negative net worth of $127.2 billion, according to an annual financial report issued by State Auditor Elaine Howle and the Bureau of State Audits. The report, which covers the fiscal year ending June 30, 2012, says that the state’s negative status — all of its assets minus all of its liabilities — increased that year, largely because it spent more than it received in revenue. [emphasis mine]

None of this is a surprise. California voters chose Jerry Brown and the Democrats to lead them into more debt.

Astronomers watch the central supermassive black hole of a galaxy eat something, either a planet or a brown dwarf.

Astronomers watch the central supermassive black hole of a galaxy eat something, either a planet or a brown dwarf.

Astronomers were using Integral to study a different galaxy when they noticed a bright X-ray flare coming from another location in the same wide field-of-view. Using XMM-Newton, the origin was confirmed as NGC 4845, a galaxy never before detected at high energies. Along with Swift and MAXI, the emission was traced from its maximum in January 2011, when the galaxy brightened by a factor of a thousand, and then as it subsided over the course of the year. “The observation was completely unexpected, from a galaxy that has been quiet for at least 20–30 years,” says Marek Nikolajuk of the University of Bialystok, Poland, lead author of the paper in Astronomy & Astrophysics.

By analysing the characteristics of the flare, the astronomers could determine that the emission came from a halo of material around the galaxy’s central black hole as it tore apart and fed on an object of 14–30 Jupiter masses. This size range corresponds to brown dwarfs, substellar objects that are not massive enough to fuse hydrogen in their core and ignite as stars. However, the authors note that it could have had an even lower mass, just a few times that of Jupiter, placing it in the range of gas-giant planets.

James Hansen is retiring from NASA and will dedicate his time to global warming activism.

James Hansen is retiring from NASA and will dedicate his time to global warming activism.

All that is really changing is that Hansen will no longer work for the government. The activism has been going on for a very long time.

Also, it is interesting how this New York Times article seems very unaware of this fact, which makes all of Hansen’s global warming claims very suspect. Might the Times not want the public to know this annoying detail?

At a cave rescue course

Posting this weekend is light because I am attending a class here in Tucson on cave rescue. Today, Saturday, was a mostly in class session going over the basics, most of which I am very familiar with from many years of experience. We did spend ninety minutes learning how to carry people around in a sked or sled, two different types of equipment used to carry a patient through difficult cave passage. In this case the terrain was simulated by going up, over, under, and around scaffolding and vehicles inside a garage. Lots of fun.

On Sunday we will be doing a mock rescue, whereby we will arrive at a cave entrance where we will have to locate the patient in the cave and get that person out of the cave safely. Should be most interesting.

Riverdance – violins

An evening pause: I am usually not a big fan of the big production Irish shows like Riverdance or Celtic Woman, as often the heart of the music gets lost in the big production. Here, however, they keep it somewhat simple, and the result is we see some good fiddling.
