Anyone who read and remembers Jeffery Kooistra’s “Kittens” series in Analog magazine back in the 1990’s will take note of this news story…

Flip of Single Molecular Switch Makes Old Brain Young

Short form: Around the time of adolescence, the brain goes from constantly rewiring itself – which makes learning easy – to a more fixed configuration.Yale researchers figured out the gene sequence responsible for this in mice, and tinkered, resetting mouse brains back to the childlike-flexibility. An advantage of this is that child brains are more easily repaired than adult brains… getting bashed on the noggin or having a stroke can be recovered from more quickly and completely if your brain is able to rewire itself easily.

If you could reset an adult human brain to the easily rewired configuration, it *might* make said human extremely smart and innovative. Or it might make said human a psychopath, a schizophrenic, or perhaps some wholly new form of disconnected-from-reality-crazy. Who knows. But it’s worth an experiment or three. If the same process that works on mice can work on humans, an obvious set of experiments is to try it out on  people who have just had massive strokes or other brain damage. Perhaps try it out on people with bad aneurisms or rain tumors, people whose brains haven’t been damaged *yet,* but who know that it’s only a matter of time.

I suspect chances are good that a combo of brain damage and increased brain plasticity might result in the patient eventually becoming an entirely different person… the memories might be there, but the personality has the potential to completely reprogram itself.

One of the more useful and interesting resources for aerospace researchers and historians has been the NASA Technical Report Server. Millions of documents available for download. But now, it seems, a Chinese spy has ruined it for everyone. Pull up NTRS now, and you see:

Until further notice,
the NTRS system will be unavailable for public access.
We apologize for any inconvenience this may cause you and anticipate that this site will return to service in the near future.

What’s the cause of this? It’s not certain, but it’s a safe bet that just-arrested alleged Chinese spy Bo Jiang was at the heart of this. SpaceRef.com has some interesting and depressing info:

Washington, D.C. (March 18, 2013) – Rep. Frank Wolf (R-VA), chairman of the House Appropriations subcommittee that funds NASA, today held a press conference revealing a significant new development concerning a Chinese national allegedly involved in security violations at several NASA centers.

NASA should immediately take down all publicly available technical data sources until all documents that have not been subjected to export control review have received such a review and all controlled documents are removed from the system.

Arrrgh.

It’s hard to see how a spy would have made use of NTRS. Did he upload sensitive documents for the world to see? Seems unlikely. Did he download stuff from there he shouldn’t have? Hard to imagine much on NTRS that would have been of concern… plus, it was available to anyone on the planet with an internet connection. I suspect China had downloaded everything on NTRS and has their own backup of the archive.

Supreme Court rules against publisher on copyright protections

I first mentioned this case back in October, the Supreme Court has now ruled. In short: a Thai national came to the US to get a college education, found that the price of textbooks was insanely high. The same textbooks are offered in Thailand for far less. So he had his family send him textbooks from Thailand. Then he had them send *more* textbooks from Thailand, which he then sold for a profit in the US. The textbook publishers claimed that he was violating their copyright by reselling stuff he bought legally. It has long been accepted that Americans can resell stuff they bought… so long as what they bought was made in the US. But until this case came up, many people – myself included – had been unaware that there was even a hint that you were not allowed to resell something you bought, if it was made outside the US.

Strangely, the Supreme Court ruled on the side of common sense here, in a  6-3 decision: if you bought it, you can resell it. This has a few implications:

1) Books, obviously. Why buy the “American market edition” if a foreign edition is vastly cheaper?

2) Ipods, Ipads, other electronics: Americans get to pay Full Price, yet Chinese and such pay dirt cheap prices. Now, either that means that Apple really can make a profit off of an ipad that costs (handwave) fifty bucks… or Apple loses money on these sales and makes up for it via the high American prices. In other words, American consumers are subsidizing third-world consumers. In either event, it’s safe to assume that there will not be people scooping up large numbers of cheapo Ipads and such from the dirt-world markets and reselling at a substantial markup in the US market (but still substantially cheaper than MSRP). The end result of *that* will be:

A) Either the foreign prices will skyrocket to prevent that

B) US prices will plummet

C) The foreign versions will be made fundamentally different from US versions (Chinese language only, say)

3) Drugs. How many times have we heard about an American who needs  drugs only to find that the American-available drug costs several orders of magnitude more than the exact same drug available just across the border? (such as HERE, where a $100 scorpion anti venom dose was marked up by a factor of 390 for the US market) While I have no doubt that there are a passel of laws and regulations about importing and reselling drugs, I would also have no doubt that someone – probably many someones – are going to try to use this ruling to find a workaround to allow Americans to buy much needed medicines for roughly the sort of prices the rest of the world pays. And why not? It’s about time the US stopped subsidizing everyone else.

For the past week I’ve been hoping to get photos of the comet, mostly without success… clouds and mountains have presented troubles. Tonight I finally got sight of the thing, just before it set. In the future I hope to improve upon this.

In lieu of good comet photos, I did get some decent shots of the evening sky.

An early 1980’s Bell Helicopter artists concept of what would become the V-22 Osprey. The design is largely right, though the canopy is noticeably different. Note the refueling probe above the nose and the Gatling gun projecting from the tip of the nose.
