irving47 writes 'With the economy the way it is, it's a little iffy to even think about switching careers completely, but lately, I've gotten more and more fed up with trying to keep up with the technical demands of companies and customers that are financially and even verbally unappreciative. While I might be good at it, and the money is adequate, I'm curious to hear from Slashdotters who have gone cold-turkey from their IT/Networking careers to something once foreign to them. How did you deal with the income difference, if any? Do you find yourself dealing with people more, and if so, how did that work out?'

anglico sends news of research out of the University of Rochester that has identified a gene that "cancer-proofs" cells in rodents. "Despite a 30-year lifespan that gives ample time for cells to grow cancerous, a small rodent species called a naked mole rat has never been found with tumors of any kind — and now biologists at the University of Rochester think they know why. The findings, presented in the Proceedings of the National Academy of Sciences, show that the mole rat's cells express a gene called p16 that makes the cells 'claustrophobic,' stopping the cells' proliferation when too many of them crowd together, cutting off runaway growth before it can start. The effect of p16 is so pronounced that when researchers mutated the cells to induce a tumor, the cells' growth barely changed, whereas regular mouse cells became fully cancerous."

According to Professor Svante Paabo, director of genetics at the Max Planck Institute for Evolutionary Anthropology, Neanderthals and modern humans had sex across the species barrier. The professor has been using DNA retrieved from fossils to piece together the entire Neanderthal genome, and plans on publishing his findings soon. He recently told a conference that he was sure the two species had had sex, but still had questions as to how "productive" the relations had been. "What I'm really interested in is, did we have children back then and did those children contribute to our variation today?" he said. "I'm sure that they had sex, but did it give offspring that contributed to us? We will be able to answer quite rigorously with the new [Neanderthal genome] sequence." What remains a mystery is what Paleolithic brewery provided the catalyst for these stone age hook-ups.

dwheeler writes "The US Department of Defense has just released a new official memo on open source software: 'Clarifying Guidance Regarding Open Source Software (OSS).' (The memo should be up shortly on this DoD site.) This memo is important for anyone who works with the DoD, including contractors, on software and systems that include software; it may influence many other organizations as well. The DoD had released a memo back in 2003, but 'misconceptions and misinterpretations... have hampered effective DoD use and development of OSS.' The new memo tries to counter those misconceptions and misinterpretations, and is very positive about OSS. In particular, it lists a number of potential advantages of OSS, and recommends that in certain cases the DoD release software as OSS."

Ponca City, We love you writes "The LA Times reports that in an effort to push consumers toward buying more movies, some major film studios are considering a new policy that would block DVDs from being offered for rental until several weeks after going on sale. Under the plan, new DVD releases would be available on a purchase-only basis for a few weeks, after which time companies such as Blockbuster and Netflix would be allowed to rent the DVDs to their customers. 'The studios are wrestling with declines in DVD sales while the DVD rental market has been modestly growing,' says Reed Hastings the CEO of Netflix. 'If we can agree on low-enough pricing, delayed rental could potentially increase profits for everyone.' Three studios have already tried to impose a no-rental period of about a month on Redbox, the operator of kiosks that rent movies for $1 per night, believing that Redbox's steeply discounted price undercuts DVD sales. Redbox has responded by suing the studios, seeking to force them to sell it DVDs simultaneously with competitors. Meanwhile, the company is stocking its kiosks with DVDs it can't otherwise obtain by buying them from retailers."

IP-192.com was one of several readers to note that Google Voice users can now utilize their existing mobile phone number for collecting voice messages instead of applying for a Google Voice number. From the post at the Google Voice blog: "Up until now, if you wanted to use Google Voice, you needed to choose a new number. Taking calls through your Google number allows us to offer features like call recording, call screening and getting text messages via email." Not all features (like conference calling) are available to those bringing their own number, but voice messages by email is my favorite feature.

Barence writes "Social-networking site Facebook is planning to preserve the accounts of dead members. The new 'memorialized' accounts will continue to display photos and wall posts, but remove 'sensitive information' such as status updates and contact information. Friends or family who want to report the death of a Facebook member are encouraged to fill out the site's Deceased form. The form asks for proof of death, such as an obituary or news article, although it's not clear how Facebook can validate the death of a member if neither of those pieces of information is published on the internet. How long before someone snuffs it on Facebook before their time?"

KentuckyFC writes "There is absolutely, positively, definitely no chance of the LHC destroying the planet (or this way either) when it eventually switches on some time later this year. And yet a few niggling doubts are persuading some scientists to run through their figures again. One potential method of destruction is that the LHC will create tiny black holes that could swallow everything in their path, including the planet. Various scientists have said this will not happen because the black holes would decay before they could do any damage. But physicists who have re-run the calculations now say that the mini black holes produced by the LHC could last for seconds, possibly minutes. Of course, the real question is whether they decay faster than they can grow. The new calculations suggest that the decay mechanism should win over and that the catastrophic growth of a black hole from the LHC 'does not seem possible' (abstract). But shouldn't we require better assurance than that?"

ffs writes "The next release of Fedora, 11, will default to the ext4 file system unless serious regressions are seen, as reported by heise online. The LWN story has a few comments extolling the virtues of the file system. Some benchmarks have shown ext4 to be much faster than the current default ext3. Some of the new features that matter for desktop users are a faster file system check, extents support (for efficiently storing large files and reducing fragmentation), multiblock allocation (faster writes), delayed block allocation, journal checksumming (saving against power / hardware failures), and others. The KernelNewbies page has more information on each feature. As is the extfs tradition, mounting a current ext3 filesystem as ext4 will work seamlessly; however, most new features will not be available with the same on-disk format, meaning a fresh format with ext4 or converting the disk layout to ext4 will offer the best experience."

NewYorkCountryLawyer writes "Unhappy with Harvard Law Professor Charles Nesson's motion to compel the deposition of the RIAA's head 'Enforcer', Matthew J. Oppenheim, in SONY BMG Music v. Tenenbaum, the RIAA threatened the good professor with sanctions (PDF) if he declined to withdraw his motion. Then the next day they filed papers opposing the motion, and indeed asked the Court to award monetary sanctions under Rule 37 of the Federal Rules of Civil Procedure."
