The fives ages of the brain

brain of manJust for a change, I’m going to post a link without running my metaphorical mouth off about the article in question. New Scientist has been running a multi-part feature on the five ages of the human brain – from gestation to ageing and senescence – with loads of related material on the side, and I thought those of you who’ve not read it already might find it very interesting.

There’s a kind of final frontier aspect to neuroscience that really intrigues me; it’s got the same sensawunda kick that good sf gives, as well as a sense of potential that’s starting to rival pure technology as we develop the ability to observe and test the systems in close detail. For example: sew a new set of hands onto someone, and their nervous system gets busy with rewiring the connections and making them work like the originals. That’s a pretty good resilience feature right there, wouldn’t you say? Especially considering it’s a built-in capability of the unmodified 1.0 release…

Ambulances of the future

sc_shellSome elegant concept design for ambulances of the future, produced by the Royal College of Art and Engineering and Physical Sciences Research Council here at the BBC:

The idea of emergency on-the-spot community treatment was introduced by the government in 2001. However, experts say research into new technologies needed to support this new role is still lagging.

Mr Thompson continues: “We are looking at enabling technologies to help ECPs do their job.”

One such design is called the shell concept. It has a removable ‘shell’ that can slide off the main vehicle to create an expanded treatment space, or left on the scene for extended periods of time.

Other proposals include a soft continuous silicone interior which morphs to the shape of the patient and allows for infection control as well as a deployable tent allowing 360 degree access to patients.

Does journalism need Arianna Huffington, or is it the other way round?

Doubtless you’ve already heard the hot new angle to the ongoing Death Of Journalism meme – Arianna Huffington of the Huffington Post blog (which is really way to big to be fairly labelled a blog any more, I think) has started a foundation to fund the ‘proper’ investigative journalism that has been so sorely lacking in recent years… with respect to, for example, the invasion liberation of oil-rich countries and the collapse of high-finance Ponzi schemes.

Jeff Jarvis sees this as a harbinger of things to come, suggesting that a small elite with money to spare will benevolently support investigative journalism for the benefit of all:

This, I believe, is how journalism will get money directly from readers—not through subscriptions, micropayments, and pay walls but from the generous contributions of the few who pay for efforts that benefit the many. That is the 1 percent rule behind Wikipedia: 1 percent of its readers write it. And that is how public broadcasting is supported today in the U.S. I can’t imagine the public wanting to pay to buoy the sinking Titanics of old-media failures; I don’t want to contribute to failed newspapers anymore than I want my tax money going to failed banks and auto companies. But I can imagine readers contributing to assure that government is watched.

Now, maybe I’ve just been over-trained to the cynical mindset of the science fictional thinker, but I’m really struggling to find any advantage in this idea by comparison to the status quo, above and beyond the fact that someone will be paying journalists to do something.

Nick Penniman, the fund’s executive director, vowed that the work produced through The Huffington Post Investigative Fund would be non-partisan. He said: “We care about democracy, not Democrats.”

Great institutions are built with the best of intentions… but once they become a system in their own right, they develop all the dark nooks and bolt-holes for corruption that their predecessors had. I honestly believe HuffPo cares about democracy, but that’s because the people running it still care. Time corrupts and disillusions us; systems and organisations expand, and idealism is diluted. The HuffPo foundation will still be an organisation with a pot of money that pays lumps of that money to journalists for what it considers to be good stories… which is different to newspapers how, exactly? Caesar hears what is pleasing unto Casear, after all… especially when he’s sitting on your paycheck.

Just to make it plain, I’m not throwing accusations of corruption, cynicism or partisanship toward anyone involved in what is evidently an admirable and philanthropic project. I’m merely suggesting that those things are emergent properties of any hierarchical system, and to imagine the same snowblindness that affects established ‘old media’ can be avoided simply by having one’s heart in the right place strikes me as a little naive.

Investigative journalism will always struggle while the majority of news consumers fail to realise how important it is; news consumers will only support investigative journalism financially when they can see tangible examples of it working directly for their benefit. So, I believe that foundations might be a solution, but only ones that are driven from the end-user level have even the remotest chance of not drifting onto someone’s party line.

Journalism doesn’t need the Huffington Post… but the top dogs of politically-focussed new media need the legitimacy of old-school journalism to cement their standing in the eyes of the politicians and their voters. Discuss.

Warp Factor Zero

Star Trek trikeThe science fictional faster-than-light warp drive, despite being a staple of books and movies in which scientific plausibility is at best a tertiary consideration, is actually based on a genuine scientific theory by a fellow called Miguel Alcubierre.

Unfortunately for those looking forward to boldly going where no human has gone before (and doubtless delivering colonial civilisation and moral homilies to aliens with suspiciously lumpy yet humanoid faces), an expansion of Alcubierre’s theory to include quantum mechanics suggests that the warp drive is not a phenomenon we’ll actually be able to use for space travel after all:

Alcubierre imagined a small volume of flat spacetime in which a spacecraft might sit, surrounded by a highly distorted bubble of spacetime which shrinks in the direction of travel, bringing your destination nearer, and stretches behind you. He showed that this shrinking and stretching could enable the bubble–and the spaceship it contained–to move at superluminal speeds.

The conclusion is the result of classical thinking using the ideas of general relativity but physicists have long wondered what would happen if you threw quantum mechanics into the mix? Now Finazzi and pals have worked it. For a start, they say that the inside of the bubble would be filled with Hawking radiation, making life rather uncomfortable for any spacecraft within it.

Not to mention for the occupants of said spacecraft… I guess we’ll just have to put off establishing the Galactic Federation and learn how to make do with what we have to hand, at least until some benevolent sponsor race gives us the key to the subatomic universe.

Recycled plastics make crims harder to catch

heaps of plastic for recyclingThe increasing prevalence of recycled plastics in the manufacturing industry – doubtless due in part to the currently-struggling Chinese trash-trawling industry – means that a lot of everyday objects are now made from what you might call “mongrel plastics”, a blend of different chemicals with similar physical properties. Which is good news… unless you’re a detective who needs to lift fingerprints from the stuff, that is.

The recycled products may look similar, but the physical and chemical properties differ so widely from the plastics they replace that the techniques honed over recent decades to lift fingerprints off plastics are no longer effective, he says.

Traditionally plastics were made from just one or two chemical building blocks, arranged in a predictable structure. But even plastics with just a trace of recycled feedstock become much more complex. Although consumers are encouraged to separate their plastics for recycling, the resulting plastics are inevitably more of a mongrel product than the pedigree plastics they replace.

Now there’s a nice little rogue state niche industry waiting to be exploited – custom mongrel plastics that defy forensics efforts. The cost of hiring an out-of-work plastics geek would be offset by the higher prices you could charge to your secretive customers. [image by meaduva]
