Hugh Pickens writes "Work resumed this week on the five-year project to link a chain of tower-mounted sensors and other surveillance equipment over most of the 2,000-mile border with Mexico. The network of cameras, radar, and communications gear is intended to speed deployment of US Border Patrol officers to intercept illegal immigrants, drug smugglers and other violators, yielding greater 'operational control' over the vast and rugged area. A $20M pilot project for the Secure Border Initiative, or 'SBInet,' carried out in the Bush administration, was generally considered a colossal IT failure. Since that time the DHS has given the prime contractor, Boeing, another $600M. The government says it has learned many lessons and made many changes in the program since the previous pilot rushed off-the-shelf equipment into operation without testing. The Obama administration has lowered the cost estimate for the 5-year project by $1.1B, to $6.7B, mainly by deferring work on the most difficult 200 miles of the border, in southwest Texas."

schwit1 writes "A report from The Scientific Committee on Antarctic Research says that Antarctic ice is growing, not melting away. Ice core drilling in the fast ice off Australia's Davis Station in East Antarctica by the Antarctic Climate and Ecosystems Co-Operative Research Centre shows that last year, the ice had a maximum thickness of 1.89m, its densest in 10 years. The average thickness of the ice at Davis since the 1950s is 1.67m. A paper to be published soon by the British Antarctic Survey in the journal Geophysical Research Letters is expected to confirm that over the past 30 years, the area of sea ice around the continent has expanded."

Miracle Jones writes "Amazon has instituted an overnight policy that removes books that may be deemed offensive from their search system, despite the sales rank of the book and also irrespective of any complaints. Bloggers such as Ed Champion are calling for a 'link and book boycott,' asking people to remove links to Amazon from their web pages and stop buying books from them until the policy is reversed. Will this be bad business for Amazon, or will their new policies keep them out of trouble as they continue to grow and replace bookstores?"

Peter N. M. Hansteen writes "Once you've identified spam senders, OpenBSD provides all the tools you need to take one step further: exporting their addresses and publishing the evidence. You can even trap them yourself using known bad addresses. It's easy, fun and good netizenship."

Soychemist writes "Some people have a mutation that makes them highly resistant to HIV, and scientists think that they can give that immunity to anyone with a new type of gene therapy. The first human trials will start at the University of Pennsylvania this week. Researchers will draw blood from people with drug-resistant HIV, clip the CCR5 gene out of their T-cells with a nuclease enzyme, grow the modified cells in a dish, and then return 10 billion of them to the patient's bloodstream. Those cells will be immune to the virus, and they will keep the patient's T-cell count up even if the rest are destroyed. 'We will see if it is safe and if those cells inhibit HIV replication in vivo,' said the lead researcher. 'We know they do in the test tube.'"

rs232 writes with a link to a story at The Register which begins: "The executive in charge of the BBC iPlayer has suggested that internet users could be charged £10 per month extra on their broadband bill for higher quality streaming." The article suggests (perhaps optimistically) that "after years of selling consumers pipes, not what they carry, [tiered, site-specific pricing] would be tough to pull off."

SpaceAdmiral notes the news that scientists have succeeded in convincing experiment subjects that a mannequin's body is their own, and even feeling at home in the body of someone of the opposite sex. The effect could prove useful in virtual reality applications and in robot technology. Here's the paper on PLoS ONE.

somanyrobots writes with an interesting followup in the New York Times to the earlier-reported substantial reconstruction of the woolly mammoth genome: "Scientists are talking for the first time about the old idea of resurrecting extinct species as if this staple of science fiction is a realistic possibility, saying that a living mammoth could perhaps be regenerated for as little as $10 million. The same technology could be applied to any other extinct species from which one can obtain hair, horn, hooves, fur or feathers, and which went extinct within the last 60,000 years, the effective age limit for DNA." (The Washington Post article linked from the earlier post was much more skeptical, calling such an attempt "still firmly the domain of science fiction." The New York Times article, while describing the process in similar terms, also calls attention to recent advances in sequencing DNA, as well as recoding DNA for cloning.)

Celery writes "There's an interview with Ray Kurzweil on silicon.com talking up the prospects of gene therapy as a means to reverse human aging, discussing different approaches to developing artificial intelligence, and giving his take on whether super intelligent machines could ever have souls. From the interview: 'The soul is a synonym for consciousness ... and if we were to consider where consciousness comes from we would have to consider it an emerging property. Brain science is instructive there as we look inside the brain, and we've now looked at it in exquisite detail, you don't see anything that can be identified as a soul — there's just a lot of neurons and they're complicated but there's no consciousness to be seen. Therefore it's an emerging property of a very complex system that can reflect on itself. And if you were to create a system that had similar properties, similar level of complexity it would therefore have the same emerging property.'"

Brian D. writes "I've recently begun working with a group that sends books to prisoners in federal and state prisons. We try to match their requests as well as we can. One request that we consistently have trouble filling is for computer books. This is not for lack of books, but because the prisoners' requests tend to be vague and their computer resources are obviously severely limited. Keep in mind that we send prisoners all types of books — from gardening and landscaping to cooking and sailing — about topics they don't have the resources to experiment with. With basically one shelf devoted to books on computing, what types of books should I tell them we should keep? What are the best types of books to send a prisoner who requests a book on 'computer repair?'"

haroldag writes "I thoroughly enjoyed the recent post about Unix tricks, so I ask Slashdot vim users, what's out there? :Sex, :b#, marks, ctags. Any tricks worth sharing?"

Chris_Keene writes in to let us know that the Prof. Michael Reiss, who recently caused a storm with comments about teaching creationism in schools, has resigned from his post as director of education at the Royal Society in the UK. This news coincides with word out of the Anglican church that it is ready to apologize to Charles Darwin, 150 years after it poured scorn on his theory of evolution by natural selection. "The Church of England will concede in a statement that it was over-defensive and over-emotional in dismissing Darwin's ideas. It will call 'anti-evolutionary fervor' an 'indictment' on the Church."

JagsLive notes a patent application filed in the US by Nokia for a way to 'scribble on the back' of digital photos. Nokia's approach is similar to the iPod's Cover Flow, except that Nokia users will be able to flip through their snaps, select one, and then turn it over and annotate the back just using SMS-like text entry. The scribble becomes an integral part of the saved photo.

arcticstoat writes "In a bid to deter people from using pirate versions of Windows XP, Microsoft is now updating its Windows Genuine Advantage (WGA) tool to introduce a few uncomfortable niggles for users of pirated versions of Windows. These include replacing the desktop wallpaper with a black screen every 60 minutes, although you can still replace it with your wallpaper of choice in the intervening period. As well as this, copies of Windows deemed to not be genuine will also have a translucent watermark above the system tray, which Microsoft calls a 'persistent desktop notification.'"
