Smart dust, er, dew

Smart Dew electronic bugHere’s another military sf trope to add to the list of fictional gadgets gradually becoming a battlefield reality. This time it’s the turn of smart dust… though the team at Tel Aviv University have called it ‘smart dew’ instead:

Dozens, hundreds and even thousands of these Smart Dew sensors – each equipped with a controller and RF transmitter/receiver – can also be wirelessly networked to detect the difference between man, animal, car and truck.

[snip]

Each individual “dew droplet” can detect an intrusion within a parameter of 50 meters (about 165 feet). And at a cost of 25 cents per “droplet,” Prof. Shapira says that his solution is the cheapest and the smartest on the market.

A part of the appeal of Smart Dew is its near-invisibility, Prof. Shapira says. “Smart Dew is a covert monitoring system. Because the sensors in the Smart Dew wireless network are so small, you would need bionic vision to notice them. There would be so many tiny droplets over the monitored area that it would be impossible to find each and every one.”

Not quite the nanoscopic modular machines of fiction, then, but surely their primitive progenitors. Not to mention another example of military hardware that will litter disputed regions for years to come… somehow I doubt they’ve done much planning about how to retrieve them all once their job is done.

Friday Free Fiction for 27th March

I knew it was too good to last; a solid week of sunny weather, and now it seems we’re back to grey skies and low temperatures. But hey, the sun always shines on the internet (provided you’re searching the right tags on Flickr), and there’s always free science fiction stories at Futurismic on a Friday afternoon…

***

Via Jonathan Strahan, we discover that Night Shade Books have made Ted Chiang’s Hugo-nominated short story “Exhalation” available for free in a variety of formats: PDF, HTML, RTF and Mobipocket

***

Mary Robinette Kowal is a Hugo nominee, too; go check out her “Evil Robot Monkey

***

Lou Anders of Pyr reveals that the short story “A Book of Silences” by James Enge is now gracing their free samples page; looks to be more in the fantasy line than we’re usually interested in here at Futurismic, but hey, nothing says you can’t read other stuff too, right?

***

We’re up to chapter 4.1 with Jason Stoddard‘s Eternal Franchise

***

A message from Lee Gimenez:

My science fiction story “The Wellness Center” was just published in the March edition of Aphelion Magazine.

Congratulations, Lee, and thanks for the tip-off!

***

As we’ve thrown some fantasy into the mix, why not a soupcon of horror, too? Tim Lebbon announces an excerpt from his new novel Bar None:

It’s a novel of  ‘chilling suspense, apocalyptic beauty, and fine ales’.   So as a pre-weekend treat, the first ever extract is now available at Dread Central for your perusal and delectation. It reads with a soft fruity aromas, a smooth mouthfeel, and finishes with a dark and complex aftertaste.

Knowing Lebbon, he was probably half-cut when he wrote it, too…

[ Disclosure – Tim Lebbon is one of my clients, and is not really a heavy drinker. Or so he claims. ]

The DVD Extras are coming thick and fast for Season 2 of Shadow Unit; this one’s called “Ice

***

Strange Horizons presents “The Spider in You” by Sean E Markey

***

HUB Magazine presents “Hush a Bye” by Beverley Allen

***

Mary Robinette Kowal pops up again, this time at BoingBoing in her capacity as editor of Shimmer Magazine:

“For Shimmer magazine’s 10th issue, we’ve got twelve fantastic new stories and an interview with none other than Cory Doctorow. In honor of Cory’s work with Creative Commons, we are giving away the pdf of issue ten as a free download.”

Jayme Lynn Blaschke‘s Memory rolls onwards with its thirty-fifth chapter.

***

The SF Signal crew have been gathering free fiction links like gangbusters this week, so it appears. There are two massive roundup posts as well as the following tidbits:

That should keep your eyeballs busy for a few hours… don’t forget to keep us informed if theres anything you think deserves a plug here at friday Free Fiction, and have a great weekend!

The silicon brain

neural networkMost attempts to simulate the function of organic brains using computers have been software simulations – models built with code, if you like. An international team of computer scientists have been trying the other approach, however: building computer hardware that mimics the dense interconnection of brain cells.

The hope is that recreating the structure of the brain in computer form may help to further our understanding of how to develop massively parallel, powerful new computers, says Meier.

This is not the first time someone has tried to recreate the workings of the brain. One effort called the Blue Brain project, run by Henry Markram at the Ecole Polytechnique Fédérale de Lausanne, in Switzerland, has been using vast databases of biological data recorded by neurologists to create a hugely complex and realistic simulation of the brain on an IBM supercomputer.

The advantage of this hardwired approach, as opposed to a simulation, Karlheinz continues, is that it allows researchers to recreate the brain-like structure in a way that is truly parallel. Getting simulations to run in real time requires huge amounts of computing power. Plus, physical models are able to run much faster and are more scalable. In fact, the current prototype can operate about 100,000 times faster than a real human brain. “We can simulate a day in a second,” says Karlheinz.

A day in a second, huh? That’s straight out of your favourite Singularity sf story, right there. [image by neurollero]

Transhumanists talk a great deal about the inevitability of human-equivalent artificial intelligence in the very near future, and it’s easy to dismiss them as dreamers until you read an article like this. I’m not saying that silicon brainware means the Singularity is inevitable, or even likely… but I think I’ll start learning to speak in machine code. Y’know, just in case.

Oddball galaxy discovered

The Centaurus A galaxySeems there’s always something new to discover in the field of astronomy. The latest nugget of cosmological excitement is a tiny, dark-matter-free and closely-packed galaxy out in the direction of the Sombrero:

“It was only the size of a star cluster – which typically contain about one million stars – but it shone as brightly as a small galaxy. This indicated the object was an ultra-compact dwarf galaxy, a very unusual object, possibly containing 10 million stars,” he said.

[snip]

“There is much debate in the astronomical community about how these things form. The prevailing theory is that they are dwarf galaxies that have been stripped of their outer halo of stars by the gravitational forces of the large parent galaxy, leaving only the bright inner core of stars. But we think it may be something else: a massive star cluster that has formed independently,” Hau explains.

Another unusual aspect of the ultra-compact dwarf galaxy is that it is very old – perhaps 10 billion years, indicating it was formed in the early stages of the universe, when things were all the more violent and energetic. Furthermore it appears to consist mainly of stars, rather than the still-enigmatic dark matter, which dominates the mass of most galaxies.

Small it may be, but SUCD1 is hardly peaceful, spitting out a powerful stream of X-rays. The team believes this to be the first time that X-ray emissions have been clearly detected from an ultra-compact dwarf object.

So, not your average ball of stars, then. And it may well turn out to be a natural (if freakish) example of the way the universe evolved…

… but indulge me a minute here, OK? An object much smaller than a normal galaxy, but which shines as brightly as one; an unusual topography of stellar density; an absence of the dark matter we’re accustomed to finding in such objects; a fierce source of X-ray emissions. You know that theory that says we’re most likely to find other advanced civilisations by looking for evidence of mega-engineering projects on the scale of Dyson Spheres and so on? Well, if I was one of the guys at SETI, I’d be booking some radio telescope time to scope out that little dwarf cluster.

Just sayin’. 😉

[Yeah, I know it’s probably just the first weird little galaxy of its type we’ve seen. But what can I say? I like Greg Egan novels. Image by thebadastronomer; it’s not of the galaxy in question, I’m afraid, but it is very pretty.]

Global collapse? What global collapse?

Apocalypse later?Futurist Brian Wang has had it with the doom-mongershe’s pretty sure there’s not going to be any global collapse, and he’s got a list of reasons why. Here are just a few:

1. Efficiency, conservation and an energy plans can be enhanced beyond current levels with minimal strain. There has been partially voluntary reductions in energy demand during the credit crisis. 10% reductions with minimal effort and 20% reductions with more austerity.

OK, seems reasonable.

5. In regards to global warming and environmental concerns:

  • a rapid switchover to totally clean power would stop the air pollution of coal and most oil and would greatly reduce any additional CO2
  • geoengineering can be used to reduce global temperatures if necessary
  • if the beliefs of climate change being from man-made sources are right then we are already geoengineering by accident as a side effect of our industry. It will be cheaper and easier to geoengineer to cancel those accidental side effects with intentional reversal efforts

Well, possibly, but geoengineering is a very speculative field indeed, as noted yesterday. And how are you going to defeat the political inertia on energy source changes?

9. Financial doom scenarios

  • Mandated resets of debt forgiveness, re-issuing script etc… can be used to reboot a country or a financial system
  • People and systems for production would still exist even if there was 1000 trillion in debt

Yes, but where’s the motivation for those hungry and desperate people going to come from?

Wang’s points all make sense, but they all seem to assume the presence of a strong and clearheaded global or national leadership which, most importantly, hasn’t lost the respect of its subjects or its power to organise them into productive and efficient units.

Wang frequently compares these potential responses to war-time mobilisation efforts, and as regards the scale of effort needed that comparison has validity. But I’m not so certain about his confidence in the psychology of a mobilisation of that sort; before his list, he says:

One thing of note is that most people usually think that Hitler and Stalin were bad guys for killing or causing the death of about 100 million people. Most of the civilization die off scenarios are that level of death each and every year for 70 years. 1000 times the number of deaths in the holocaust. Why is there the belief that significant mitigation efforts would not be made ?

Because political rhetoric is more easily focussed on an enemy with a face, perhaps?

The problem with existential threats is that they’re hard for our fundamentally selfish and short-range psychology to focus on. When you’ve not got enough to eat, your first priority will be filling your stomach, not saving the world. Mobilising people on the scale of nations takes a government with its people’s ear and trust, or at least their obedience under pressure… and with exception of some of the more totalitarian regimes on the planet, those are in short supply at the moment, and likely to be more so as the number of tangible existential risks increases, in my opinion.

What do you think – would the world come together in the face of a genuine extinction event, or would it be every man for himself in the last days of civilisation?
