Aristos Mazer sends word of research out of iRobot on a "chembot," or morphing blob robot, that looks like dough and moves by shifting its sides from solid-like to liquid-like states. This will allow it, in theory and after lots of refinement, to pass through cracks by squeezing. iRobot calls the new technique "jamming." The research project was funded by DARPA. The video clearly shows the early stage the work is in, but when you think about it the possibilities are a little unsettling.

Last year we discussed the work of Richard Lenski, who has been breeding E. coli for 21 years in a laboratory in Michigan. Then, the news was that Lenski's lab had caught direct, reproducible evidence of a genetic mutation with functional consequences for an organism. Now Lenski's lab has published in Nature a major study comparing adaptive and random genetic changes in 40,000 generations of E. coli (abstract here). "Early changes in the bacteria appeared to be largely adaptive, helping them be more successful in their environment. 'The genome was evolving along at a surprisingly constant rate, even as the adaptation of the bacteria slowed down,' [Lenski] noted. 'But then suddenly the mutation rate jumped way up, and a new dynamic relationship was established.' By generation 20,000, for example, the group found that some 45 genetic mutations had occurred, but 6,000 generations later a genetic mutation in the metabolism arose and sparked a rapid increase in the number of mutations so that by generation 40,000, some 653 mutations had occurred. Unlike the earlier changes, many of these later mutations appeared to be more random and neutral. The long-awaited findings show that calculating rates and types of evolutionary change may be even more difficult to do without a rich data set."

Now that the Kindle is being actively marketed in many countries outside the US, reader rsmiller510 sends in his piece up on DaniWeb about the skepticism in Germany about the whole e-book phenomenon. A major difference from the US book market is that in Germany, book prices are regulated in an effort to protect authors, publishers, and small booksellers. As a result, publishers don't issue electronic versions of their books until the paperback edition comes out, up to 2 years after the hardcover — and then they sell the e-book for the same price as the lowest-cost paperback. An article on e-books in Spiegel.de notes a survey taken recently for the Frankfurt Book Fair, which found that "only one in 12 Germans has a clear idea about what an e-book is, and seven out of 10 of them would prefer a printed version over a digital one." 65,000 e-books were sold in Germany in the first 6 months of 2009, vs. almost ten times that number bought per week in the US, in what is still a small niche of the overall book business.

ewsnow writes "The Focus Fusion Society reports that the scientists and engineers at Lawrenceville Plasma Physics have finally built an operational Dense Plasma Focus device. While still at less than half power, they were able to achieve a pinch on their device. The small company that Eric Lerner started recently gathered enough funding to start a two-year study on the validity of his theory regarding fusion-inducing plasmoids. If the theory holds, the device will produce more electricity than it consumes. In contrast to the billions of dollars spent on Tokamak fusion (think ITER), LPP is conducting their research on a budget around a million dollars. Yet, if it works, it will provide nuclear fusion with much simpler equipment and much less cost. Eric Lerner and Focus Fusion have been discussed on Slashdot before."

jammag writes "Well, c'mon, yes — let's admit it. As a veteran coder discusses as he looks at his career, software development is brimming with the offbeat, the quirky and the downright odd. As he remembers, there was the 'Software Lyrics' guy and the 'Inappropriate Phone Call' programmer, among others. Are unique types drawn to the profession, or are we 'transformed over time by our darkened working environments and exposure to computer screen radiation?'"

The Installer writes "Wizards of the Coast is in the process of settling its claim against several individuals for illegal distribution of its newest copyrighted handbook. 'In one of three lawsuits brought by Wizards of the Coast LLC, a subsidiary of Hasbro Inc., US District Judge Thomas S. Zilly on Friday accepted a settlement in which Thomas Patrick Nolan of Milton, Fla., agreed to a judgment against him of $125,000.' These were the lawsuits that went along with WotC's decision to stop selling the handbook in .PDF format. 'According to court filings, more than 2,600 copies of the handbook were downloaded from Scribd.com, and more than 4,200 copies were viewed online before the material was pulled from the document-sharing site at Wizards' request.'"

An anonymous reader writes "Researchers at MIT's Robust Robotics Group have developed a robotic helicopter capable of autonomously flying inside buildings or other GPS-denied environments. It has an on-board camera and a laser scanner that maps the local environment. The video talks about search-and-rescue and civil engineering applications, but it also brings somewhat scary reminders of Minority Report to my head. How long till I see one of these chasing me down a dark alley? The team's website has more videos showing earlier stages of the project."

misnohmer writes "Verizon has just launched a new set of ads confirming the rumors of its upcoming iPhone competitor: 'Unlike previous Android phones, the Droid is rumored to be powered by the TI OMAP3430, the same core that the iPhone and Palm Pre use, and which significantly outperforms Qualcomm 528MHz ARM11-based Android phones that exist today. Droid will also be running v.2.0 of Android, with a significantly upgraded user interface. The Droid poses a different and more significant challenge to the iPhone than any other phone to date. The Palm Pre could have been that challenger, but it lacked the Verizon network, and users were unimpressed with the hardware. According to people who've handled the device, the Droid is the most sophisticated mobile device to hit the market to date from a hardware standpoint. When you combine that with the Verizon network, you've got something that is most definitely a challenger to the Jesus phone.'"

ZosX writes "Around 11:45 PM Friday night, I was prompted by Firefox that it had disabled the addons that Microsoft has been including with .NET — specifically, the .NET Framework Assistant and the Windows Presentation Foundation. The popup announcing this said that the 'following addons have been known to cause stability or security issues with Firefox.' Thanks, Mozilla team, for hitting the kill switch and hopefully this will get Microsoft to release a patch sooner." Here's the Mozilla security blog entry announcing the block, which Mozilla implemented via its blocklisting mechanism.

Hugh Pickens writes "The president of the Maldives and 11 ministers, decked out in scuba gear, held a cabinet meeting 4m underwater to highlight the threat of global warming to the low-lying Indian Ocean nation. While officials said the event itself was light-hearted, the idea is to focus on the plight of the Maldives, where rising sea levels threaten to make the nation uninhabitable by the end of the century. President Mohamed Nasheed and his cabinet spent half an hour on the sea bed, communicating with white boards and hand signals and signed a document calling for global cuts in carbon emissions. The Maldives has already begun to divert a portion of the country's billion-dollar annual tourist revenue to buy a new homeland as an insurance policy against climate change that threatens to turn the 300,000 islanders into environmental refugees. Emerging out of the water, a dripping President Nasheed removed his mask to answer questions from reporters and photographers crowded around on the shore. 'We are trying to send a message to the world about what is happening and what would happen to the Maldives if climate change isn't checked,' he said, bobbing around in the water with his team of ministers. 'If the Maldives is not saved, today we do not feel there is much chance for the rest of the world.'"

We may have to rethink the assumption that Silicon Valley is the hotbed of innovation in which all the world's best and brightest want to work and live. TechCrunch has a piece by an invited expert on the reverse brain drain already evident and growing in the US as Indian, Chinese, and European students and workers in the US plan to return home, or already have. From an extensive interview with Chinese and Indian workers who had already left: "We learned that these workers returned in their prime: the average age of the Indian returnees was 30 and the Chinese was 33. They were really well educated: 51% of the Chinese held masters degrees and 41% had PhDs. Among Indians, 66% held a masters and 12% had PhDs. These degrees were mostly in management, technology, and science. ... What propelled them to return home? Some 84% of the Chinese and 69% of the Indians cited professional opportunities. And while they make less money in absolute terms at home, most said their salaries brought a 'better quality of life' than what they had in the US. ... A return ticket home also put their career on steroids. About 10% of the Indians polled had held senior management jobs in the US. That number rose to 44% after they returned home. Among the Chinese, the number rose from 9% in the US to 36% in China."

TheClockworkSoul sends in an article up at Scientific American, from which we quote: "Stem cells so far have been used to mend tissues ranging from damaged hearts to collapsed tracheas. Now the multifaceted cells have proved successful at regrowing bone in humans. In the first procedure of its kind, doctors at Cincinnati Children's Hospital Medical Center replaced a 14-year-old boy's missing cheekbones — in part by repurposing stem cells from his own body. To create the new bones, which have become part of the patient's own skull structure and have remained securely in place for four and a half months, the medical team used a combination of fat-derived stem cells, donated bone scaffolds, growth factors, and bone-coating tissue. The technique, should it be approved for widespread use, could benefit some seven million people in the US who need more bone — everyone from cancer patients to injured war veterans."

maximus1 writes "If you're selling skills gained in an open source project, you have additional opportunities to shine, say experts in this ITWorld article. But what is the best way to explain your FOSS experience? 'Someone stands out because of how they talk about the project, says Zack Grossbart, author of The One Minute Commute. His advice is to describe the project and discuss your contributions in detail: 'If you were a committer, what did you do to earn that status? What features did you work on? Did you design new areas, or just implement predefined functions? Did you lead meetings? Define new architecture? Set the project direction?' If the FOSS experience is part of your background but not a shining beacon or job equivalent, it's common to list it under 'other experience.' Andy Lester, author of Land The Tech Job You Love, says: 'Think of each project as a freelance job that you've worked on. Just as different freelance gigs have varying sizes and scopes, so too does each project to which you contribute. The key is to not lump all your projects under one "open source work" heading.' Good examples are worth a thousand words. Grossbart offers up his resume as a sound but not perfect example (PDF) that includes open source experience. (His article on how to format your resume might also be of interest.)"

beadwindow writes "NASA's IBEX (Interstellar Boundary Explorer) spacecraft has made the first all-sky maps of the heliosphere and the results have taken researchers by surprise. The maps are bisected by a bright, winding ribbon of unknown origin: 'This is a shocking new result,' says IBEX principal investigator Dave McComas of the Southwest Research Institute. 'We had no idea this ribbon existed — or what has created it. Our previous ideas about the outer heliosphere are going to have to be revised.' Another NASA scientist notes, '"This ribbon winds between the two Voyager spacecraft and was not observed by either of them.'"

The Atlantic is running a major article questioning the received wisdom about flu vaccines and antivirals, for both seasonal flu and H1-N1. "When Lisa Jackson, a physician and senior investigator with the Group Health Research Center, in Seattle, began wondering aloud to colleagues if maybe something was amiss with the estimate of 50 percent mortality reduction for people who get flu vaccine, the response she got sounded more like doctrine than science. 'People told me, "No good can come of [asking] this,"' she says... Nonetheless, in 2004, Jackson and three colleagues set out to determine whether the mortality difference between the vaccinated and the unvaccinated might be caused by a phenomenon known as the 'healthy user effect.' Jackson's findings showed that outside of flu season, the baseline risk of death among people who did not get vaccinated was approximately 60 percent higher than among those who did, lending support to the hypothesis that on average, healthy people chose to get the vaccine, while the 'frail elderly' didn't or couldn't. In fact, the healthy-user effect explained the entire benefit that other researchers were attributing to flu vaccine, suggesting that the vaccine itself might not reduce mortality at all."
