Jaguars and GPS

May 23rd, 2005

Jaguars, which once roamed across Central America and were worshipped as gods by the Mayans, are now in serious decline. Reuters reports on a Mexican-Guatemalan project to fit jaguars with Global Positioning Systems (GPS) units so that their movements can be tracked by satellites. It is hoped that a better understanding of jaguars’ movements will help protect them and the habitat upon which they depend.

Although it is not mentioned in the Reuters article, presumably the project also will utilize Geographic Information Systems (GIS). Individuals jaguar’s movements will be overlaid on digital geographic layers of natural and human features to determine the threat posed by shrinking jaguar habitats (using layers such as vegetation, rivers) as well as expanded human activities (layers such as roads, farms). Researchers and practitioners will then be able to look at which jaguars are encroaching on farms, need to travel across roads to eat and mate. Also, I assume they’ll be looking for instances, sadly, when the GPS units are no longer transmitting or moving.

For my more activist readers: Lest we automatically reject the importance of considering local human activity such as cattle ranching, remember that it’s the local people one has to convince in order to preserve the wild species. Conservation International, one of the lead conservation non-governmental organizations on this project, has had many successes not, I would argue, because they use lots of GIS but because they involve local people in day-to-day conservation.

Computer technology meets organic vegetables

May 22nd, 2005

In honour of Star Wars III: Revenge of the Sith, see the organic foods version of Star Wars, Grocery Store Wars. (Someone needs to explain to me why a cannoli is included in the cast of characters.)

For some reason, organic food producers seem to be attracted to sf films as a way to promote their vision. For another example, see The Meatrix.

Ok, for another video, which draws on toilet themes of earlier posts (here, here and here), see this extremely silly Japanese advertisement.

Touch nature, virtually

May 21st, 2005

Via slashdot

Wired News reports that researchers have developed a computer system to allow physical interaction over the Internet. The system enables touching and feeling [tele-haptic sensing] of animals or other humans in real time, but it’s first being tried out on chickens. Researchers call it the “first human-poultry interaction system”, although they don’t explain why the chickens (actually roosters).

The Touchy Internet was built by researchers at the Mixed Reality Lab at the National University of Singapore (NUS) (with teams in other places such as Austria). Click on it. These guys have the coolest research website I’ve ever seen. Check out their video section, especially the ones on Human Pacman.

The immediate use, which comes to mind, is porn. After all, porn represents the number one use of the Internet. The Wired article mentions the possibility for rescue workers to remotely communicate with dogs as they search in dangerous or remote places. I wonder if this technology could be used as a component of nature interpretation, either in a virtual interpretive center or as a way for disabled people to interact with nature. Or it could be used to advance protection of distance habitats. For example, if we could touch them, would it help us better empathize with baby seals in northern Canada and therefore more vigourously protest the seal hunt? If we could pet dolphins, would we engage in protecting sea mammals from fishing? We could think of any number of environments that might benefit from tele-haptics.

Canada and copyright law, the revenge of the courts

May 21st, 2005

CBC reports that Canadian courts have dealt a blow to the recording industry’s arguments that sharing music files breaches Canada’s copyright laws.

In a unanimous decision Thursday, the Federal Court of Appeal dismissed the Canadian Recording Industry Association’s appeal of a March 2004 ruling that said ISPs like Shaw, Rogers and Bell did not have to reveal the names of 29 users accused of sharing thousands of music files.

See previous post about how this has implications for sharing of enivornmental data.

At this same time appellate courts move to protect ISPs, the Canadian federal government moves to amend the copyright law so as to quash file sharing. According to the article, this modification would force ISPs to take an active role in prosecuting file sharing.

nuclear options become less optional

May 19th, 2005

In a realistic breakdown of energy source options, the tally puts nuclear power far in the lead. A true-to-their-roots assortment of environmental movements continue to speak out against shifting energy supply to nuclear power plants, refusing to budge. Greenpeace sent an emergency email requesting petitions in favor of Sen. McCain releasing the generous subsidies for nuclear technology from the bill on climate change. They and others view such actions as a surrender, whereby conservation and clean energy are dismissed. Since when is nuclear energy such a hero?

But the long and short of it is that, as Stewart Brand and others are beginning to admit, and hard-line no-nukes folk are beginning to concede, the need for carbon-free energy eclipses the risk from nuclear power. In the three decades since a reactor has been built, technology has improved considerably; managerial concerns (the ‘Human Factor’) may never be infallible, and are what draw the most criticism towards nuclear power.

Shortly after his article in Technology Review (accompanied by a pitcure of Stewart the saintly prophet), the New York Times kicks in with a comprehensive follow-up, chock-full of reactions from across the board. Perhaps nuclear energy will get its wings after all.

See previous post for all the environmental heresies.

Whither privacy?

May 19th, 2005

There’s a new article on privacy vis-a-viz Google maps, this time from a journal for security professionals. The issue is four-fold: the amount of georeferenced data on the web allows your name to be attached to your house; the increased scale of the maps, through the satellite images, gives the viewer enormous spatial detail; that viewer isn’t necessarily you; and finally the non-linear function of the search facility may lead to unanticipated additional violations of privacy (e.g., to the work location of someone with a similar name). The main concern of the author is national security–zooming in to see the details of dams and nuclear power plants–but the concerns for the individual are more tangible.

The same week sees this article on students from John Hopkins University who, working on a course assignment, were able to gather enormous amounts of information on residents of the City of Baltimore, all from legal public sources and for practically no money. The article’s central premise is that, in the pursuit of convenience in terms of online access to information on their houses and cars, Americans have exposed themselves to invasions of privacy.

What are we to think of privacy of personal information? Some thoughts.

1. The rich will be able to protect their privacy. I’m reminded of the people in the upscale areas of NY who wanted to opt out of the book, “New York: The Photo Atlas” because it contains aerial photos of their homes, backyards, and pools. They weren’t able to remove their photos from that book. However, they have greater capacity than the less well-to-do to protect their privacy, perhaps by scrubbing unsavory details from the Internet with the help of lawyers. For an example of an early data scrubbing, see Howard Rheingold’s The Virtual Community.

2. The poor will continue to trade their privacy for access. They already fill in online surveys and allow cookies to accumulate for free email or affordable bandwidth. What else can we expect as access becomes the currency of the modern world? What’s craven is to conclude that there’s no down-side to this exchange.

3. The youth will have a very different view of privacy from adults. There are precedents since youth in some areas of the US already live with transparent backpacks and metal detectors. Youth also are creating enormous records of their lives on the Internet and with varied media such as blogs and webcams. I suspect that they’ll value far different kinds of privacy from us. For the implications of no privacy, read The Light of Other Days by the masters of a science fiction, Arthur C. Clarke and Stephen Baxter. The book presents a new device called a “WormCam,” that allows the viewer to see anyone, anywhere, at any distance and at anytime. In a world where nothing is hidden, behavior becomes extreme. Conversely, people go to any lengths to hide themselves, even to the point of losing their individual identity.

To some extent this technology makes easier problems that have always existed (e.g., cyberstalking, identity theft) and increases the vulnerability of the already vulnerable. Society and the law will be slow to adapt. However, we shouldn’t forget that people will adapt to and adapt the technology that invades their privacy.

Earthquake predictor

May 18th, 2005

Live in or planning to visit California? Suspect there’ll be an earthquake in the next 24 hours? Check out the US Geological Services’ new online Earthquake Predictor. According to the Associated Press, these are “real-time, color-coded maps that provide earthquake probabilities in a specific region. Areas shaded in red represent a high chance of strong shaking within the next 24 hours (less than a 1 in 10 chance) while those in blue represent a very remote chance, say, more than 1 in a million.” The predictive maps are updated hourly with seismic data and if you’re interested in a specific place in California, you can zoom in to take a close look.

Scientists say that it’s not designed to predict when the big quake will happen but instead where and how big the aftershocks will be.

For those of you who want more details about the models, here’s the background: Real-time Forecasts of Tomorrow’s Earthquakes in California: a New Mapping Tool.

Soocer moms go off the grid!

May 17th, 2005

Wired Magazine reports on a new generation and demographic of people deciding to reduce their reliance on traditional power. Solar panels and wind turbines are popping up all over the suburbs.

Wired calls it moving from the hardcore to the hybrid (or “hygrid”). The assumption is that the class of individual has changed. However, I would warrant that all the hippie ‘back to the landers’ in the 60s and 70s came from middle class families. What’s more interesting is the variety of reasons driving this new group of individuals:

Start with the cost of energy. Most US homes use natural gas for heat. Natural gas prices have been soaring. So has the price of electricity produced by coal-burning power plants. And that’s not even factoring in the more than $1 billion in subsidies that go to the oil and gas industry, or the environmental damage – increased greenhouse emissions and mercury pollution – caused by burning fossil fuels.

At the same time, the conventional power grid is showing signs of age. Energy use has increased far more quickly than capacity has been added. So blackouts and brownouts occur more often. According to Jay Apt, director of the Electricity Industry Center at Carnegie Mellon University, every four months the US endures a blackout large enough to cut power to half a million homes. Add the threat of terrorism, and homeowners understandably want greater security and control over their power. “I’d rather do it myself than trust the experts,” Bell says. When the grid goes down, his lights stay on.

The article adds that the cost of alternate energy has decreased for the average consumer. After all, “Only a handful of hardcore greens were willing to multiply their energy bills by eight to save the planet. ” To help with the cost, some US states have stepped in to subsidize purchases. So it seems that we’re finally moving past the paradox of the cost decreasing once more people start using the technology but people will only start using the technology once the cost decreases.

Robots gone wild!

May 17th, 2005

Researchers at Cornell have just convinced robots to reproduce. That is, researchers have built block-shaped robots that are able to pick up, integrate and then hive-off the blocks to create duplicates of themselves. The video from the Cornell site is pretty cool (don’t try the mpg from the NYTimes site–it caused my computer to shut down).

The research is reported in the NYTimes, which reports on an article in Nature (sorry guys, it’s not free). I found the NYTimes article superficial, playing on the sensationalist angle (brave new world and all). Reporting at the Cornell site is better.

What the research shows me is how faaaaar we have to go before we achieve anything like what we have come to expect from movies like I Robot or earlier, Silent Running. Another site shows the state of the art on robot faces, fingers and eyes. It’s enlightening because the work is still primitive. We have robots in the world; they can handle the dirty jobs or give us the minimally intelligent toys. But they’re not C3PO and they are decades away from passing the Turing test.

What the research implies to me is that we have gotten blase about what our science can deliver. Science is a long slow process of careful incremental work. Rarely do advances appear quickly and never just because we wish for them. And where is the sense of wonder in this type of innovation? This is still pretty cool, even if it is blocks. I suppose the sense of wonder is drained into movies like Star Wars, which can do it all in CGI.*

The Cornell article also brings up the problem recognized by researchers in labelling this reproduction or self-replication:

human beings reproduce but don’t literally self-replicate, since the offspring are not exact copies. And in many cases, the ability to replicate depends on the environment. Rabbits are good replicators in the forest, poor replicators in a desert and abysmal replicators in deep space, they note. “It is not enough to simply say they replicate or even that they replicate well, because these statements only hold in certain contexts,” the researchers conclude. The conference paper also discusses the reproduction of viruses and the splitting of light beams into two identical copies. The analysis they supply “allows us to look at an important aspect of biology and quantify it,” Lipson explains.

Green servers

May 16th, 2005

Via slashdot, an interview with Richard Sawyer, director of data center technology for American Power Conversion Corp., on whether computer servers have innovated to be energy efficienct without giving up performance.

I found the comments to the slashdot post to be the most interesting, particularly this one from Shalda:

Your average data-center manager could not care less about whether his server farm is environmentally friendly or not. On the other hand, electricity is a major expense. A dozen racks of 1U servers pulling 100-200 watts each will probably run you upwards of $80k/year. And that doesn’t even include the cost of cooling your server room (which will add another $20k or so). Server consolidations and energy efficient servers save money. And that will always be your driving force. If company A says they have a “green” server room, it’s just marketing. Their first concern and only concern is the bottom line.

Cynical but an entry point to convincing chief financial officers to purchase energy saving devices.

Cosmos Education

May 16th, 2005

Somewhere, something incredible is waiting to be known – Carl Sagan. Interesting outreach program supported by the SETI Institiute that teaches interdisciplinary science to kids. They are dedicated to “…the role of science and technology in health, the environment, and sustainable development.” I guess searching the universe for intelligence lends one a perspective that sees Earth as a small fragile planet in need of careful management.

Will we become extinct?

May 15th, 2005

Here’s an interesting take on extinction: We will genetically modify ourselves sufficiently that we are no longer Homo sapiens sapiens.

Conversely, by modifying ourselves, we will make ourselves extinction-proof.

Scale runs amok

May 14th, 2005

Talk about jumping scale: rebuffing President Bush’s national policy, 132 American mayors embrace the Kyoto Accord on global climate change at the local level. Most of the mayors represent coastal cities and fear for the impacts on their residents and local economies.

Expo 2005: Nature’s Wisdom

May 14th, 2005

This year’s World Expo in Nagoya, Japan is subtitled Nature’s Wisdom.

Thanks to rapid technological development, the 20th Century was characterized by mass-production and mass-consumption, which in turn led to material improvements in our daily lives. At the same time, these trends resulted in various global issues such as desertification, global warming, and a shortage of natural resources. As these issues cannot be resolved by any one nation, the international community needs to unite in confronting them: we must come together and share our experience and wisdom, in order to create a new direction for humanity which is both sustainable and harmonious with nature.

Environmental considerations were taken very seriously in both the building and the subject matter on display. An environmental impact assessment was conducted and steps were taken to preserve the ponds and vegetation, although the definition the developers have for preservation of what was an existing youth park as well as the effectiveness of protecting a site that will experience 10m visitors has yet to be evaluated. Numerous innovations are showcased in the park, such as wall greening, permeable pavement, bamboo for building and cooling huge buildings, biodegradable plastics for all the eating utensils, ozone to process the waste water and, I imagine, plenty of super toilets. All the buildings are designed to be broken down into modules and reused. The Expo 2005 website has plenty of artists’ renditions but few images of the actual site, so it’s difficult to get a sense of what it looks like. I gues you have to be there.

In particular, check out the NGO Global village, subtitled the ‘Interactive Fun Zone’. And what expo with nature as a theme would be complete without a pavillon on robots?


Official Mascots of Expo 2005: Morizo (Forest Grand Father) and Kiccoro (Forest Child)

The Guardian has a great review of the Expo–the article is worth reading on its own–that compares the Expo to an Edo-dynasty palace garden instead of a techno-fest. The article also contains these wonders of translation:

Following the exhortions of arcane signs through the grounds, I promised to avoid making “exhibitions of collective enthusiasm”, to refrain from “scattering gas, liquid, powder and other items”, and the “sowing of seed”.

Wired woodlands

May 13th, 2005

Take a look at the article on the Wired Woodlands. It is a small forested reserve up in the San Jacinto Mountains in southern California. The James Reserve is owned by the University of California at Riverside. It is now covered with “more than 100 tiny sensors, robots, cameras and computers, which are beginning to paint an unusually detailed portrait” of innumerable processes in the natural landscape, from nesting behaviour to soil chemistry.

I’ve been to the James Reserve several times because it is the natural home of the Society for Conservation GIS (well, ok, it’s not home but it’s the site of the original meetings of the group). I remember how exciting it was when the director of the reserve got word that he won this major National Science Foundation Grant. This represents a major innovation in the use of computers to monitor the environment.

Computers, Society, and Wikis

May 13th, 2005

An interesting personal web site I came across today, the site of Mr. Keunwoo Lee, of the University of Washington. It has a few interesting links, including a Society and technology wiki, as well as some tips he has for professors considering using wikis in courses.

Among other mildly interesting things to be found, UW seems to allow people to sign up for various credit weights for the same course, for example, if someone wishes to participate only in the discussions for credit, they can sign up for 1 credit, if they wish to present a paper in addition, they can sign up for two credits, and so on. It’s an interesting amount of flexibility, which would seem beneficial when students want to take a broader range of courses.

To request this at McGill would no doubt result in commissions to investigate the possibility of creating a steering committee to create the new forms allowing it to be passed to the senate for approval before being sent to more implementation commitees.

Earth: not so dim after all

May 8th, 2005

NYTimes reports three new papers in Science that call attention to a major gap in how the climate system works. The papers report that the Earth is brightening, that is, more sunlight is reaching the earth’s surface and is not being reflected by clouds or volcanic dust or pollution. Scientists don’t exactly know what’s causing the brightening, or how this is affecting the rest of the climate.

The findings of Dr. Wild and his colleagues are based on data through 2001 from a network of ground-based sensors that directly measure the sunlight hitting the ground. But the sensors are not evenly distributed, with the greatest number in Europe, few in Africa and South America, and none covering the 70 percent of Earth’s surface that is water.

Dr. Pinker’s team analyzed satellite data from 1983 to 2001 that covered the globe. Its findings about brightening, which basically agree with Dr. Wild’s, rely on computer models to estimate how much sunlight reaches the surface.

Finally, a team led by Dr. Bruce A. Wielicki of NASA’s Langley Research Center in Virginia reports that measurements from the agency’s Aqua satellite show a slight decrease in the amount of light reflected off Earth since 2000, which corresponds to a brightening on the surface.

So whom does one believe? The models or the sensors or the images? And why isn’t the Earth dimming like the models have predicted? The public likely will view this conflicting data as simply more evidence that climate change is a hoax.
