johkir writes "As early as 1965, when Al Gore was a freshman in college, a panel of distinguished environmental scientists warned President Lyndon B. Johnson that CO2 emissions from fossil fuels might cause 'marked changes in climate' that 'could be deleterious.' Yet the scientists did not so much as mention the possibility of reducing emissions. Instead they considered one idea: 'spreading very small reflective particles' over about five million square miles of ocean, so as to bounce about 1 percent more sunlight back to space — 'a wacky geoengineering solution.' In the decades since, geoengineering ideas never died, but they did get pushed to the fringe — they were widely perceived by scientists and environmentalists alike as silly and even immoral attempts to avoid addressing the root of the problem of global warming. Three recent developments have brought them back into the mainstream." We've discussed some pretty strange ideas in the geoengineering line over the last few years.

Because the number of abductions in Mexico has jumped almost 40% in the past 3 years, the wealthy are getting subcutaneous transmitters so they can be tracked when kidnapped. Xega, the Mexican security firm which makes the chips, has seen a sales jump of 13% this year. The company injects the crystal-encased chip, the size and shape of a grain of rice, into clients' bodies with a syringe. The chip then sends radio signals to a larger device carried by the client with a global positioning system in it. A satellite can then be used to find the location of the missing person. Things must be a lot worse in Mexico than I thought.

This year at OSCON it seemed that you couldn't throw a stone without hitting someone from Microsoft (and in fact, I'm sure several people did). They were working very hard to make themselves known, and working desperately to change public opinion of Microsoft's involvement in the open source community. Linux.com's Nathan Willis took a look at what they were preaching, with a hefty dose of skepticism, and tries to postulate what the "angle" is. Of course, the powers that be at Microsoft may have finally seen the writing on the wall and felt the pressure from Google enough to alter their strategy a bit. For now I guess we'll have to wait with guarded optimism (or laughable contempt, depending on how old/jaded you are).

hightower_40 writes to mention that a small Alaskan village has sued two dozen oil, power, and coal companies, blaming them for contributing to global warming. "Sea ice traditionally protected the community, whose economy is based in part on salmon fishing plus subsistence hunting of whale, seal, walrus, and caribou. But sea ice that forms later and melts sooner because of higher temperatures has left the community unprotected from fall and winter storm waves and surges that lash coastal areas."

Andrew Feinberg writes "A California State Senator is seeking to mandate climate change as part of the standard science curriculum. Other members of the legislative body seek to teach an opposing view. 'Simitian noted that his bill wouldn't dictate what to teach or in what grades, but rather would require the state Board of Education and state Department of Education to decide both. Although global warming is mentioned in high school classes about weather, it is currently not required to be covered in all textbooks, said the head of the California Science Teachers Association ... teachers would have plenty to discuss: rising levels of carbon dioxide, how temperatures are measured globally, and what is known and not known about global warming.'"

An anonymous reader writes "The world's most powerful functional rail gun capable of accelerating projectiles up to Mach 8 has been delivered to the Navy. The new rail gun is a 32-megajoule Electro-Magnetic Laboratory Rail Gun. The Navy eventually hopes to have 64-megajoule ship mounted rail guns. 'The lab version doesn't look particularly menacing -- more like a long, belt-fed airport screening device than like a futuristic cannon -- but the system will fire rounds at up to Mach 8, drawing on tremendous amounts of electricity to generate the current for each test shot. That, of course, is the problem with rail guns: Like lasers, they're out of step with modern-day generators and capacitors. Eight and 9-megajoule rail guns have been fired before, but providing 3 million amps of power per shot has been a limitation.'"

Ant writes "CNET News.com reports on the reasons behind the unpopularity of DVD recorders in the US. The devices, which have seen heavy support in Europe and Asia, fall flat in the United States. The biggest reason is the penetration of Cable television. With cable, the same show can appear on a channel several times. In Europe and Japan, viewers need to grab copies of shows when they can, as it could be some time before the episode is broadcast again. TiVo also took off more rapidly in the States and elsewhere. TiVo is also one of the reasons selling TVs with embedded hard drives in the States remains a challenge."

theodp writes "Ready for one-automobile-per-child (OAPC)? India's giant Tata Group is on the verge of launching the world's cheapest car. The People's Car, slated to be unveiled January 10th at a New Delhi auto show, will carry a sticker price of 100,000 rupees ($2,500), which some analysts say could revolutionize automobile costs worldwide. The Tata is a pet project of Cornell-trained architect Ratan Tata, who helped design it. The vehicle is aimed at improving driving safety by getting India's masses off their motorbikes and into cars."

An anonymous reader writes "PC Magazine reviews the $200 Linux desktop wonder sold by Wal-Mart. This desktop sold out quickly and has been cited as proof that consumers are tired of the Windows tax and ready for Linux. Not so according to PC Magazine, which gave the gPC a 1.5 star rating." Previous discussions we've had about system reviews were realistic but not quite so harsh; is this just nitpicking or is the 'shiny' starting to wear off of the cheap Linux PC concept?

DeeQ writes "Ask.com is betting that it will. The search engine is working on a service called AskEraser that will attempt to obscure the searches a user enters into the site. 'Some privacy experts doubt that concerns about privacy are significant enough to turn a feature like AskEraser into a major selling point for Ask.com. The search engine accounted for 4.7 percent of all searches conducted in the United States in October, according to comScore, which ranks Internet traffic. By comparison, Google accounted for 58.5 percent, Yahoo for 22.9 percent and Microsoft for 9.7 percent.'" We first discussed this project back in July.

PCOL writes "Salar de Uyuni is a vast plain of white salt in the mountains of Bolivia, with a total elevation range of less than 80 centimeters - the flattest place on earth. Beginning in 2002, geophysicist Adrian Borsa led a survey that resulted in precise GPS measurements of the salt flat. The flats will be used as a giant calibration device for satellite-based radar and laser altimeters on the CryoSat recovery mission so the spacecraft can more precisely monitor changes in the elevation and thickness of polar ice sheets and floating sea ice. 'Satellites can calibrate their altimeters by bouncing signals off the ocean surface .. because of atmospheric interference, tides and waves, there are uncertainties. Borsa says the salar, now so accurately mapped and with dry, clear skies, is about five times better than the ocean as a reference point.'"

Ponca City, We Love You writes "The New Scientist reports that palaeontologists have excavated a fossil trackway in Shandong Province in China 100 to 120 million years old that contains footprints left by six Dromeosaurs, the more formal name for raptors, showing evidence of group behavior. Up until now, the popular stereotype from Jurassic Park of raptors hunting in packs has had no fossil evidence to back it up. The paths of the six 90 kilo raptors do not overlap where the animals walked alongside a river or stream. '"The odds of these tracks being made by different individuals that just happen to be moving in the same direction, without their tracks stepping on one another, are small," said Jerry D. Harris, director of paleontology at Dixie State College. "Groups that do that usually have relatively sophisticated behavior, and they're relatively intelligent," Harris added. "By moving together in groups, it's entirely possible that they hunted in groups."'"

Bridgestone, the company which debuted the "world's thinnest" sheet of two-color e-paper last year, has turned around and delivered a new version which is capable of displaying over four thousand colors. "In case that wasn't enough, the company is also touting what it calls the "world's largest full color e-paper that is A3 size, which is equivalent to a 21.4-inch screen." As you'd expect, the latter is expected to be used solely for advertising and could hit the market as early as next year, while the former technology is set to be commercially available in 2009."

An anonymous reader writes to let us know that Verizon Wireless is planning to share its customers' calling records (called CPNI) with "our affiliates, agents and parent companies (including Vodafone) and their subsidiaries." The article explains that CPNI "includes the numbers of incoming and outgoing calls and time spent on each call, among other data." Some subscribers, it's not known if it's all of them, received a letter in the mail giving them 30 days to opt out of this sharing by calling 1-800-333-9956. Skydeck, a mobile and wireless services company, seems to have been the first to call attention to the Verizon initiative on their blog; they also posted a scan of the letter (sideways PDF) from Verizon.
