There's a VERY easy way to stop MUCH of the Microsoft supported liberal garbage, simply notify Microsoft that because of their financial and name support of liberal corruption that you are going to openly publicize and promote freeware replacements to their software products.

...that NEON, which endeavors to study, document, and integrate our lives more closely into the natural world is named after a substance that has no known biological role?
Is this about them Arr Eff Eye Dee things my nephew is always goin on about?
With thunderous applause.
Wouldn't having tons of sensors all over the place somehow contaminate the very environment they are trying to test? I mean.. animals aren't all oblivious to foreign objects in their world and are prone to changing behavior in response to them. I've seen documentaries about herds that move differently thanks to things like the Alaskan pipeline, roads across wild places in Africa, and the like. Lots of little sensors in the rivers, forests, plains, etc. would likely have some kind of impact. Plus, if there's millions of them, they are going to go clean them up someday, right.... right?

Sensor Webs and Smart Dust and related tecnologies will prove valuable in ecological studies and environmental monitoring, but that's not the drive behind them.
In Vietnam the US military attempted to install networks of sensors - seismographs, detectors for urine and sweat, detectors for nitrogen compunds (explosives), movement detectors, proximity detectors - along known NLF supply lines and for perimeter defence. They were put in place by Special Forces teams and transmitted their data to overflying aircraft for targetting. Often they were woeful failures or could be spoofed by the NLF.
Here is the new generation, just ready for "assymetric warfare".
Having participtated in small scale ecology studies, I would guess that these senors will raise many more questions (which would be a good definition of the "new windows") than answers. Population ecology and the evolutionary biology that ties into it is a field with many more 'big' questions than most people realize.
In most of the primary literature I cover, for every possible cause of a behavior (such as migratory routes) that is eliminated, another 2 consistently appear (seriously). I think we will see some very interesting questions, rather than any definite answers (at least in the short term). I would definitely like to see this used with the arctic tern.
"The Times reports 'scientists want to deploy millions of these kinds of devices over large tracts for long periods, opening new windows on nature.'""
Well there goes any forays into the woods with your girlfriend.
Ie.. when monitoring pollution, they'd go out and put out test equipment, take a reading, move to the next spot, take a reading....
With a distributed system, you can get data from a network of sensors by relaying data across the field.
A sensor net is a good idea

When you have a crime to investigate, and you have no suspects, where do you start? Obviously you begin by looking at the person or persons who have the most to gain by perpetrating the crime.
This is why we must consider: who had something to gain from the disasterous crimes of September 11th? Obviously not Osama Bin Laden, who would net no financial windfall from the destruction of the World Trade Center and the Pentagon. Although he has loudly applauded the "terrorist" acts of September 11th and even tacitly taken credit for them, there is no reason to believe that he is anything more than a bandwagon jumper. Being blamed for the destruction of the World Trade Center has done more for his image than any amount of militant Islamic rhetoric.
But if not Bin Laden, then who?
It so happens that on December 11th, "coincidentally" 2 months after the tragedy, Credit Suisse First Boston quietly agreed to pay out US$100 million in order to settle an 18 month old investigation into its handling of certain high-profile technology IPOs (Initial Public Offerings). One of the most controversial amongst these being the IPO of VA Linux Systems, Inc. (LNUX) .
VA Linux Systems, Inc., now known as VA Software, is widely derided as a poster child of the dot-com bust, though inexplicably still in business. At the time of the IPO, VA Linux (Software) shares opened trading at nearly 10 times their $30 offer price, closing the first day of trading at $239.25. This meteoric rise made many early investors rich, strangely on account of a company which purports to sell a hobbyist operating system which can be obtained for free on the Internet. "The VA Linux initial public offering is a prime example of market manipulation in an IPO by investment banks, their customers and the issuing firm," said Steven Schulman, a partner in the law firm Milberg Weiss Bershad Hynes & Lerach, which specializes in filing shareholder suits.
"Because certain favored customers of the investment banks agreed to buy shares in a new issue at inflated prices in the aftermarket (in return for getting an allocation of the shares at the initial offering price) the share prices to which the IPO eventually soared were actually driven by artificial market forces," continues Schulman.
But what does the VA Software (Linux) IPO have to do with the attacks on September 11th, and what has that to do with the Credit Suisse settlement? Well, considering that VA Linux (Software) got CSFB into trouble in the first place, it stands to reason that the VA Linux (Software) Board of Directors were complicit in the stock fraud from beginning to end. As the investigation progressed against CSFB, the unscrupulous VA Software/Linux executives, their pockets bulging with filthy lucre plundered from trusting, hard-working investors, must have realized that their days in the country club were numbered if the SEC discovered their wrongdoings.
The SEC, or Securities Exchange Commission, is a federal regulatory agency, and cannot be bribed. Therefore, with a possible stint in federal prison looming large, Larry Augustin and the rest of the crooks, including outspoken gun violence advocate Eric S. Raymond, decided to undertake more active means to halt the investigation.

I wonder how much things like the movie The Day After Tomorrow and such influenced people to get these things out and deployed, both for the reason that they're good for genuine science and also because someone agreed to pay for them after seeing that movie.

Sensor Networks have been around years before that movie and there have been more deployments than just this one.
What are you expecting to find here?

you call this weather?
no need to fret (unless you're associated/joined at the hype with, unprecedented evile), it's all just a part of the creators' wwwildly popular, newclear powered, planet/population rescue initiative/mandate.
or is it ground hog day, again? many of US are obviously not interested in how we appear (which is whoreabull) from the other side of the 'lens', or even from across the oceans.
vote with (what's left in) yOUR wallet. help bring an end to unprecedented evile's manifestation through yOUR owned felonious corepirate nazi life0cidal glowbull warmongering execrable.
we still haven't read (here) about the 2/3'rds of you kids who are investigating/pursuing a spiritual/conscience/concious re-awakening, in amongst the 'stuff that matters'? another big surprise?
some of US should consider ourselves very fortunate to be among those scheduled to survive after the big flash/implementation of the creators' wwwildly popular planet/population rescue initiative/mandate.
it's right in the manual, 'world without end', etc....
as we all ?know?, change is inevitable, & denying/ignoring gravity, logic, morality, etc..., is only possible, on a temporary basis.
concern about the course of events that will occur should the corepirate nazi life0cidal execrable fail to be intervened upon is in order.
'do not be dismayed' (also from the manual). however, it's ok/recommended, to not attempt to live under/accept, fauxking nazi felon greed/fear/ego based pr ?firm? scriptdead mindphuking hypenosys.
for each of the creators' innocents harmed, there is a debt that must/will be repaid by you/us, as the perpetrators/minions of unprecedented evile, will not be available.

Sorry to tell you this but real scientists in the real world usually dont base a whole lot of their research on hollywood movies, especially ones with obvious agendas such as this one. To be honest this is the type of movie anyone with any understanding of the scientific method finds extremely annoying as suddenly everyone walking around is an "expert" on global warming because they saw this movie. Just because you saw it on TV doesnt make it true.

This reminds me of an article in the new "Innovators Section" as seen in Time magazine.
Essentially, it discusses Kris Pister who developed Smart Dust - a wireless network of sensors, called motes. Each mote has a chip about the size of a grain of rice that detects and records things like termperature and motion at its location. The motes have minisule radio transmitters that talk to otehr motes. With a single network of 10,000 motes, the upper limit, you could cover some 9 sq. miles - and get information about each point along the way!
Anyway, here's a brief description:

Frightening technology in many respects, but I can't help but smile at the thought of the brilliance behind it all.

Sensor Network research has been going on for quite some time. CENS isn't the only place doing the research. Some of the original work actually came from SCADDS from USC/ISI, with some of the same people now at CENS. All the UCs are very involved in Sensor Networks, Berkeley for example was the orginator of the current most popular hardware, the motes, now manufactured by Crossbow. Intel also makes their own version of the motes, though they are not sold comertially yet.
Most of the hardware runs in a specific OS called TinyOS, which is open source. Other hardware, like the Stargates (also from Crossbow) run an arm version of debian.
You can find lots of neat info about Sensor Networks from the specialized conferences like Sensys, IPSN, etc.
Most of the projects done with Sensor Networks have been geared towards the biological monitoring fields. However, the funding comes in from NSF as well as DARPA so sometimes it is security/military based.
It's an interesting world out there...

Reply . . . let's get it over with.
I just finished a course on this particular subject actually. A few fun comments.
In one biological study in Maine (Great Duck Island) it seems that the birds on the island they were monitoring had been attacking the sensor motes. In another case these devices offered the first look ever at night time migration patterns of zebras.(aka ZebraNet)
As far as military applications go the one that I am most aware of is DARPA's sniper net. It's a system of audio sensors designed to locate and pinpoint snipers based on gunshot triangulation.
There are some earthquake structural monitoring systems being built in California as well.
However things to be cautioned about. The smaller motes do not have very much in the way of processing power(ie can't even do floating point) so there's no need to get really paranoid about secret cameras. Most of the motes with cameras are big enough you'd probably notice them if you were looking. Primarily the motes are equipped with various sensor banks for things such as Light, Temp, Vibration, Audio, etc etc. Also if you're interested in working with the software for these things the primary OS people use is TinyOS. However a word of caution, if you want to muck around inside the inner workings of TinyOS you're pretty much on your own and some of the things are already legacy. The coolest part of sensor nets, in my opinion,is the ability to do in network data processing as the data is funneled through the network. Oh and there's already a Database system designed for use in these systems. It's name is TinyDB(surprising naming scheme I know)

So I can install wmweather on my desktop and get information about how the weather is outside since I don't see it from my cubicle. Even if it looks a bit weird that I get weather data for a city in Germany from a site in the United States. :-)
From watching nature, experts across the centuries have found uncommon wisdom. What will a shaman do with 100,000 sensor feeds? Perhaps she'll be checking terabytes of data between ecosystems for what is normal and what is not. The shamans almanac. And sensor networks will saturate our own environments just as naturally. Tons of new, never before available data waiting to be mined for more knowledge. Should be very interesting. Ted

This is actually true. Several months after they'd installed the systems, the NVA figured out that they had systems that sniffed for urine, sweat, explosives, etc. Suddenly the U.S. began detecting massive troop movements through pretty random areas of the jungle. When they sent teams to investigate, they found buckets of stale piss nailed to trees...
This system was held up as a classic example of government waste: multibillion dollar system defeated by buckets of piss.

Report: Paleontologist "fudged" discovery to promote movie
Museum of the Rockies paleontologist Jack Horner "fudged" information about a dinosaur discovery four years ago to promote the third "Jurassic Park" film, National Public Radio reported Wednesday.
Horner disputes altering dinosaur discovery for movie opening
BOZEMAN -- Paleontologist Jack Horner, who served as a science consultant for the "Jurassic Park" films, acknowledged that the announcement of a dinosaur find in eastern Montana was delayed to help promote the third installment of the dinosaur-flick franchise four years ago.
And the NPR report (audio) that broke the story:

Advertisers are finding new and creative ways to sell their films. [...] One studio has even manipulated a scientific discovery to coincide with the opening of a film. A look at some of the tactics studios use to seduce moviegoers to their films.
