kkleiner writes "For many years countless individuals in the US have had to watch with envy as dogs and horses with joint and bone injuries have been cured with stem cell procedures that the FDA has refused to approve for humans. Now, in an exciting development, Regenerative Sciences Inc. in Colorado has found a way to skirt the FDA and provide these same stem cell treatments to humans. The results have been stunning, allowing many patients to walk or run who have not been able to do so for years. There's no surgery required, just a needle to extract and then re-inject the cells where they are needed. There has always been a lot of hype around stem cells, but this is the real deal. Real humans are getting real treatment that works, and we should all hope that more companies will begin offering this procedure in other states soon."

macslocum writes "Nat Torkington begins sketching out an open data process that borrows liberally from open source tools: 'Open source discourages laziness (because everyone can see the corners you've cut), it can get bugs fixed or at least identified much faster (many eyes), it promotes collaboration, and it's a great training ground for skills development. I see no reason why open data shouldn't bring the same opportunities to data projects. And a lot of data projects need these things. From talking to government folks and scientists, it's become obvious that serious problems exist in some datasets. Sometimes corners were cut in gathering the data, or there's a poor chain of provenance for the data so it's impossible to figure out what's trustworthy and what's not. Sometimes the dataset is delivered as a tarball, then immediately forks as all the users add their new records to their own copy and don't share the additions. Sometimes the dataset is delivered as a tarball but nobody has provided a way for users to collaborate even if they want to. So lately I've been asking myself: What if we applied the best thinking and practices from open source to open data? What if we ran an open data project like an open source project? What would this look like?'"

The phone, HTC's Magic, runs the Google Android mobile operating system, and is one of the more popular handsets right now. A researcher at Panda Software received one of the handsets recently, and upon attaching it to her PC, found that the phone was pre-loaded with the Mariposa bot client. Mariposa has been in the news of late thanks to some arrests connected to the operation of the botnet."

Hugh Pickens writes "Network World summarizes an RSA Conference panel discussion in which former NSA technical director Brian Snow said that cryptographers for the NSA have been losing ground to their counterparts in universities and commercial security vendors for 20 years, but still maintain the upper hand in the sophistication of their crypto schemes and in their ability to decrypt. 'I do believe NSA is still ahead, but not by much — a handful of years,' says Snow. 'I think we've got the edge still.' Snow added that that in the 1980s there was a huge gap between what the NSA could do and what commercial encryption technology was capable of. 'Now we are very close together and moving very slowly forward in a mature field.' The NSA has one key advantage (besides their deep staff of Ph.D. mathematicians and other cryptographic experts who work on securing traffic and breaking codes): 'We cheat. We get to read what [academics] publish. We do not publish what we research,' he said. Snow's claim of NSA superiority seemed to rankle some members on the panel. Adi Shamir, the "S" in the RSA encryption algorithm, said that when the titles of papers in NSA technical journals were declassified up to 1983, none of them included public key encryption; 'That demonstrates that NSA was behind,' said Shamir. Snow replied that when technologies are developed separately in parallel, the developers don't necessarily use the same terms for them."

suraj.sun writes "The virus that causes AIDS can hide in the bone marrow, avoiding drugs and later awakening to cause illness, according to new research that could point the way toward better treatments for the disease. Dr. Kathleen Collins of the University of Michigan and her colleagues report in this week's edition of the journal Nature Medicine that the HIV virus can infect long-lived bone marrow cells that eventually convert into blood cells. The virus is dormant in the bone marrow cells, she said, but when those progenitor cells develop into blood cells, it can be reactivated and cause renewed infection. The virus kills the new blood cells and then moves on to infect other cells, said. In recent years, drugs have reduced AIDS deaths sharply, but patients need to keep taking the medicines for life or the infection comes back, Dr. Collins said."

From the article: 'Once used, the bag can be knotted and buried, and a layer of urea crystals breaks down the waste into fertilizer, killing off disease-producing pathogens found in feces. The bag, called the Peepoo, is the brainchild of Anders Wilhelmson, an architect and professor in Stockholm. “Not only is it sanitary,” said Mr. Wilhelmson, who has patented the bag, “they can reuse this to grow crops.”'"

MikeChino writes "MIT scientists have discovered a never-before-known phenomenon wherein carbon nanotubes can be used to harness energy from 'thermopower waves.' To do this they coated the nanotubes with a reactive fuel and then lit one end, causing a fast-moving thermal wave to speed down the length of the tube. The heat from the fuel rises to a temperature of 3,000 kelvins, and can speed along the tube 10,000 times faster than the normal spread of this chemical reaction. The heat also pushes electrons down the tube, which creates a substantial electrical current. The system can output energy (in proportion to its weight) about 100x greater than an equivalent weight lithium-ion battery, and according to MIT the discovery 'opens up a new area of energy research, which is rare.'"

snydeq writes "InfoWorld's Neil McAllister takes a deeper look at HTML5, outlining what developers should expect from this overhaul of HTML — one that some believe could put an end to proprietary Web technologies such as Flash and Silverlight. Among the most eagerly anticipated additions to HTML5 are new elements and APIs that allow content authors to create rich media using nothing more than standards-based HTML. The standard also introduces browser-based application caches, which enable Web apps to store information on the client device. 'But for all of HTML5's new features, users shouldn't expect plug-ins to disappear overnight. The Web has a long history of many competing technologies and media formats, and the inertia of that legacy will be difficult to overcome. It may yet be many years before a pure-HTML5 browser will be able to match the capabilities of today's patchwork clients,' McAllister writes. 'In the end, browser market share may be the most significant hurdle for developers interested in making the most of HTML5. Until these legacy browsers are replaced with modern updates, Web developers may be stuck maintaining two versions of their sites: a rich version for HTML5-enabled users, and a version for legacy browsers that falls back on outdated rendering tricks.'"

swandives writes "Researchers at US-CERT have warned that software accompanying the Energizer DUO USB battery charger contains a Trojan that gives hackers total access to a Windows PC. The product was sold in the US, Latin America, Europe and Asia starting in 2007. Upon installation, the software creates the file 'Arucer.dll,' a Trojan that listens for commands on TCP port 7777. Upon receiving instructions, the Trojan can download and execute files, transmit files stolen from the PC, or tweak the Windows registry. Uninstalling the software disables the automatic execution of the Trojan. Users can also remove Arucer.dll from Windows' system32 directory and reboot the machine to disable the backdoor component."

KentuckyFC writes "Quantum cryptography uses the quantum properties of photons to guarantee perfect secrecy. But one of its lesser known limitations is that it only works if Alice and Bob are perfectly aligned so that they can carry out well-defined polarization measurements on the photons as they arrive. Physicists say that Alice and Bob must share the same reference frame. That's OK if Alice and Bob are in their own ground-based labs, but it's a problem in many other applications, such as ground-to-satellite communications or even in chip-to-chip communications, because it's hard to keep chips still over distances of the order of the wavelength of light. Now a group of UK physicists have developed a way of doing quantum cryptography without sharing a reference frame. The trick is to use entangled triplets of photons, so-called qutrits, rather than entangled pairs. This solves the problem by embedding it in an extra abstract dimension, which is independent of space. So, as long as both Alice and Bob know the way in which all these abstract dimensions are related, the third provides a reference against which measurements of the other two can be made. That allows Alice and Bob to make any measurements they need without having to agree ahead of time on a frame of reference. That could be an important advance enabling the widespread use of quantum cryptography."

Moodle is not only used by schools, colleges and universities around the world - an increasing number of healthcare organisations are putting it to good use too!

The Oxleas NHS Foundation Trust in south east London, UK, has been using Moodle for two years. Their site now has almost 200 courses and over 3,000 active users.

According to Jeff Burge, Learning & Development lead for Oxleas, "We manage all of our statutory and mandatory training, Continuing Professional Development and e-learning with Moodle, and it has been a huge success for us."

"As a public body our performance is measured by, amongst other things, our achievement against certain governance standards. The NHS Litigation Authority awarded us a full score for our Level 2 assessment in January of this year, and also highly commended our systems, helped in no small part by our utilisation of Moodle."

For further details of Oxleas' success story, and for more experiences of Moodle in healthcare, please see the discussion Moodle in healthcare in the Moodle stories forum.

theodp writes "As Tim Burton's 'Alice in Wonderland' shatters 3-D and IMAX records en route to a $116.3 million opening, the NY Times offers a rather cerebral op-ed arguing that Alice's search for a beautiful garden can be neatly interpreted as a mishmash of satire directed at the advances taking place in mid-19th century math. Charles Dodgson, who penned 'Alice' under the name Lewis Carroll, was a tutor in mathematics at Christ Church in Oxford who found the radical new math illogical and lacking in intellectual rigor. Op-ed writer Melanie Bayley explains: 'Chapter 6, "Pig and Pepper," parodies the principle of continuity, a bizarre concept from projective geometry, which was introduced in the mid-19th century from France. This principle (now an important aspect of modern topology) involves the idea that one shape can bend and stretch into another, provided it retains the same basic properties — a circle is the same as an ellipse or a parabola (the curve of the Cheshire cat's grin). Taking the notion to its extreme, what works for a circle should also work for a baby. So, when Alice takes the Duchess's baby outside, it turns into a pig. The Cheshire Cat says, "I thought it would."'"

ogre7299 recommends an announcement out of Caltech on a milestone for HIFI, the Herschel Space Observatory's Heterodyne Instrument for the Far Infrared. "The Herschel Space Observatory has revealed the chemical fingerprints of potential life-enabling organic molecules in the Orion Nebula, a nearby stellar nursery in our Milky Way galaxy. ... This detailed-spectrum, obtained with the Heterodyne Instrument for the Far Infrared (HIFI) — one of Herschel's three innovative instruments — demonstrates the gold mine of information that Herschel-HIFI will provide on how organic molecules form in space. The spectrum, one of the first to be obtained with HIFI since it returned to full health in January 2010 following technical difficulties, clearly demonstrates that the instrument is working well. ... [The HIFI instrument had previously been offline since] August 2009 when HIFI experienced an unexpected voltage spike in the electronic system, probably caused by a high-energy cosmic particle, resulting in the instrument shutting down. On 14 January 2010, HIFI was successfully switched back on using its spare electronics, with science observations commencing on 28 February."

drewsup writes "Wolfgang Sigmund, a professor of materials science and engineering at the University of Florida, has created a material modeled after spider hairs that acts as a nearly perfect water-repelling surface. Quoting Science Daily: 'A paper about the surface, which works equally well with hot or cold water, appears in this month's edition of the journal Langmuir. Spiders use their water-repelling hairs to stay dry or avoid drowning, with water spiders capturing air bubbles and toting them underwater to breathe. Potential applications for UF's ultra-water-repellent surfaces are many, Sigmund said. When water scampers off the surface, it picks up and carries dirt with it, in effect making the surface self-cleaning. As such, it is ideal for some food packaging, or windows, or solar cells that must stay clean to gather sunlight, he said. Boat designers might coat hulls with it, making boats faster and more efficient.' Hairy glass, anyone?"

Ahrens interviews Giorgio Rizzoni, an 'expert in failure analysis' at Ohio State, who describes the iterations of testing that NHTSA will likely inflict on the Toyota sample cars they have purchased, and then moves into the realm of software and systems verification: 'He explained that each vehicle contains "layers of computer code that may be added from one model year to next" that control nearly every system, from acceleration to braking to stability. Rizzoni said this software is rigorously tested, but he added: "It is well-known in our community that there is no scientific, firm way of actually completely verifying and validating software."' Ahrens ends the piece with a quote from a 2009 LA Times interview with former UCLA psychology professor Richard Schmidt about how user reports are often unreliable: 'When the driver says they have their foot on the brake, they are just plain wrong. The human motor system is not perfect, and it doesn't always do what it is told.'" Toyota is currently planning an event to challenge evidence presented by professor David W.
