Fasting Triggers Stem Cell Regeneration of Damaged, Old Immune System

schwit1 sends word of research showing that cycles of prolonged fasting can both protect the immune system from harm and also induce regeneration by causing stem cells to start renewing themselves. ‘In both mice and a Phase 1 human clinical trial (abstract), long periods of not eating significantly lowered white blood cell counts. In mice, fasting cycles then “flipped a regenerative switch, ” changing the signaling pathways for hematopoietic stem cells, which are responsible for the generation of blood and immune systems, the research showed. “PKA is the key gene that needs to shut down in order for these stem cells to switch into regenerative mode. It gives the OK for stem cells to go ahead and begin proliferating and rebuild the entire system, ” explained [study author Valter Longo], noting the potential of clinical applications that mimic the effects of prolonged fasting to rejuvenate the immune system. “And the good news is that the body got rid of the parts of the system that might be damaged or old, the inefficient parts, during the fasting. Now, if you start with a system heavily damaged by chemotherapy or aging, fasting cycles can generate, literally, a new immune system.”‘ Read more of this story at Slashdot.

Xanadu Software Released After 54 Years In the Making

redletterdave writes: “‘Project Xanadu, ‘ designed by hypertext inventor Ted Nelson to let users build documents that automatically embed the sources they’re linking back to and show the visible connections between parallel webpages, was released in late April at a Chapman University event. Thing is, development on Xanadu began in 1960 — that’s 54 years ago — making it the most delayed software in history. ‘At its simplest, Xanadu lets users build documents that seamlessly embed the sources which they are linking back to, creating, in Nelson’s words, “an entire form of literature where links do not break as versions change; where documents may be closely compared side by side and closely annotated; where it is possible to see the origins of every quotation; and in which there is a valid copyright system – a literary, legal and business arrangement – for frictionless, non-negotiated quotation at any time and in any amount.” The version released on the internet, named OpenXanadu, is a simple document created using quoted sections from eight other works, including the King James Bible and the Wikipedia page on Steady State Theory.'” Read more of this story at Slashdot.

Big Telecom: Terms Set For Sprint To Buy T-Mobile For $32B

First time accepted submitter Randy Davis (3683081) writes ‘A report from Forbes says that Sprint buying T-mobile for $32 billion is almost done. This will clearly rock the top two telecommunication companies in the U.S., Verizon and AT&T. The news report also said that T-mobile will give up 67% share in exchange of 15% share of the merged company. Officials of both Sprint and T-Mobile are confident that FCC will approve this deal since AT&T’s $48.5 billion acquisition of DirecTV got approved.’ One reason for that confidence: “The predominant feeling is that combined T-Mobile and Sprint will be able to offer greater competition to Verizon and AT&T , ranked first and second respectively in the U.S. market. It will also give Sprint greater might in the upcoming 600 megahertz spectrum auction, especially since part of it excludes both Verizon and AT&T from bidding.” InforWorld puts the potential price even higher, and points out that the deal could still fall apart.

Star Within a Star: Thorne-Zytkow Object Discovered

astroengine writes: “A weird type of ‘hybrid’ star has been discovered nearly 40 years since it was first theorized — but until now has been curiously difficult to find. In 1975, renowned astrophysicists Kip Thorne, of the California Institute of Technology (Caltech) in Pasadena, Calif., and Anna Zytkow, of the University of Cambridge, UK, assembled a theory on how a large dying star could swallow its neutron star binary partner, thus becoming a very rare type of stellar hybrid, nicknamed a Thorne-Zytkow object (or TZO). The neutron star — a dense husk of degenerate matter that was once a massive star long since gone supernova — would spiral into the red supergiant’s core, interrupting normal fusion processes. According to the Thorne-Zytkow theory, after the two objects have merged, an excess of the elements rubidium, lithium and molybdenum will be generated by the hybrid. So astronomers have been on the lookout for stars in our galaxy, which is thought to contain only a few dozen of these objects at any one time, with this specific chemical signature in their atmospheres. Now, according to Emily Levesque of the University of Colorado Boulder and her team, a bona fide TZO has been discovered and their findings have been accepted for publication in the Monthly Notices of the Royal Astronomical Society Letters.” Read more of this story at Slashdot.

Intel Announces Devil’s Canyon Core I7-4790K: 4GHz Base Clock, 4.4GHz Turbo

MojoKid (1002251) writes “Last year, Intel launched two new processor families based on the Haswell and Ivy Bridge-E based Core i7 architecture. Both chips were just incremental updates over their predecessors. Haswell may have delivered impressive gains in mobile, but it failed to impress on the desktop where it was only slightly faster than the chip it replaced. Enthusiasts weren’t terribly excited about either core but Intel is hoping its new Devil’s Canyon CPU, which launches today, will change that. The new chip is the Core i7-4790K and it packs several new features that should appeal to the enthusiast and overclocking markets. First, Intel has changed the thermal interface material from the paste it used in the last generation over to a new Next Generation Polymer Thermal Interface Material, or as Intel calls it, “NGPTIM.” Moving Haswell’s voltage regulator on-die proved to be a significant problem for overclockers since it caused dramatic heat buildup that was only exacerbated by higher clock speeds. Overclockers reported that removing Haswell’s lid could boost clock speeds by several hundred MHz. The other tweak to the Haswell core is a great many additional capacitors, which have been integrated to smooth power delivery at higher currents. This new chip gives Haswell a nice lift. If the overclocking headroom delivers on top of that, enthusiasts might be able to hit 4.7-4.8GHz on standard cooling.” Read more of this story at Slashdot.

Google To Spend $1 Billion On Fleet of Satellites

An anonymous reader writes “Google is planning to spend over $1 billion on a fleet of satellites to extend Internet access to unwired regions around the world. ‘The projected price ranges from about $1 billion to more than $3 billion, the people familiar with the project said, depending on the network’s final design and a later phase that could double the number of satellites. Based on past satellite ventures, costs could rise. Google’s project is the latest effort by a Silicon Valley company to extend Internet coverage from the sky to help its business on the ground. Google and Facebook Inc. are counting on new Internet users in underserved regions to boost revenue, and ultimately, earnings. “Google and Facebook are trying to figure out ways of reaching populations that thus far have been unreachable, ” said Susan Irwin, president of Irwin Communications Inc., a satellite-communications research firm. “Wired connectivity only goes so far and wireless cellular networks reach small areas. Satellites can gain much broader access.”‘” Read more of this story at Slashdot.

New Federal Database Will Track Americans’ Credit Ratings, Other Financial Info

schwit1 (797399) writes “As many as 227 million Americans may be compelled to disclose intimate details of their families and financial lives — including their Social Security numbers — in a new national database being assembled by two federal agencies. The Consumer Financial Protection Bureau posted an April 16 Federal Register notice of an expansion of their joint National Mortgage Database Program to include personally identifiable information that reveals actual users, a reversal of previously stated policy. The FHFA will manage the database and share it with CFPB. A CFPB internal planning document for 2013-17 describes the bureau as monitoring 95 percent of all mortgage transactions. FHFA officials claim the database is essential to conducting a monthly mortgage survey required by the Housing and Economic Recovery Act of 2008 and to help it prepare an annual report for Congress.” Read more of this story at Slashdot.

4K Displays Ready For Prime Time

An anonymous reader writes “After the HD revolution, display manufacturers rolled out gimmick after gimmick to try to recapture that burst of purchasing (3-D, curved displays, ‘Smart’ features, form factor tweaks, etc). Now, we’re finally seeing an improvement that might actually be useful: 4K displays are starting to drop into a reasonable price range. Tech Report reviews a 28″ model from Asus that runs $650. They say, ‘Unlike almost every other 4K display on the market, the PB287Q is capable of treating that grid as a single, coherent surface. … Running games at 4K requires tons of GPU horsepower, yet dual-tile displays don’t support simple scaling. As a result, you can’t drop back to obvious subset resolutions like 2560×1440 or 1920×1080 in order to keep frame rendering times low. … And single-tile 4K at 30Hz stinks worse, especially for gaming. The PB287Q solves almost all of those problems.’ They add that the monitor’s firmware is not great, and while most options you want are available, they often require digging through menus to set up. The review ends up recommending the monitor, but notes that, more importantly, its capabilities signify ‘the promise of better things coming soon.'” Read more of this story at Slashdot.
