Clever Workaround: Visual Cryptography On Austrian Postage Stamps 74

Posted by timothy
from the stamp-everything-with-tlldr dept.
An anonymous reader writes Have you heard of personalized postage stamps? You pay the value of the stamps plus a fee and the post office prints official stamps usable for postage which show (almost) anything you can put into a jpeg file. An Austrian Tibet supporter found out what 'almost' means. He submitted a picture of the Dalai Lama with the text 'His Holiness the Dalai Lama,' but the Austrian post office refused to produce these stamps. Stampnews and the Neue Zuercher Zeitung (autotranslation) reported that this had been due to pressure from the Chinese embassy in Vienna. Now there is a video showing how visual cryptography has been used to get around this attempt at censorship [caution: organ music] .

Researchers Find Evidence of How Higgs Particle Imparts Mass 91

Posted by Unknown Lamer
from the type-13-planet dept.
brindafella (702231) writes Physicists at CERN's Large Hadron Colider (LHC) ATLAS experiment have been looking through their data, and have found enough of the extremely rare "W boson" (proton-proton) collisions that they can now declare their results: They have found how the Higgs imparts mass to other particles. From the article: "'Only about one in 100 trillion proton-proton collisions would produce one of these events,' said Marc-André Pleier, a physicist at the U.S. Department of Energy's Brookhaven National Laboratory who played a leadership role in the analysis of this result for the ATLAS collaboration. 'You need to observe many [collisions] to see if the production rate is above or on par with predictions,' Pleier said. 'We looked through billions of proton-proton collisions produced at the LHC for a signature of these events—decay products that allow us to infer like Sherlock Holmes what happened in the event.' The analysis efforts started two years ago and were carried out in particular by groups from Brookhaven, Lawrence Berkeley National Laboratory, University of Michigan, and Technische Universität Dresden, Germany." Here's a pre-print of the paper.

Fresh Evidence Supports Higgs Boson Discovery 42

from the look-what-we-found dept.
An anonymous reader writes Researchers at CERN have discovered the first evidence for the direct decay of the Higgs boson into fermions, a strong indication that the particle found two years ago is the Higgs boson. From the article: "Assistant professor of physics at MIT and leader of the international effort, Markus Klute, said that his team was trying to establish if the particle that was discovered in 2012 was really consistent with the Higgs boson that was found in the Standard Model, and not one of many Higgs bosons, or an a particle that looks like it but has a different origin." Their researchers also found that the bosons also decay to fermions (fermions include all quarks and leptons) in a way that is consistent with the Standard Model Higgs. 'We have now established the main characteristics of this new particle, in its coupling to fermions and to bosons, and its spin-parity structure; all of these things are consistent with the Standard Model,' Klute says." CERN has also announced the LHC restart schedule.

New submitter velco writes: "ETH Zurich Software Reliability Lab announced JSNice, a statistical de-obfuscation and de-minification tool for JavaScript. The interesting thing about JSNice is that it combines program analysis with machine learning techniques to build a database of name and type regularities from large amounts of available open source code on GitHub. Then, given new JavaScript code, JSNice tries to infer the most likely names and types for that code by basing its decision on the learned regularities in the training phase."

H.R. Giger, Alien Artist and Designer, Dead at Age 74 92

M3.14 writes: "H. R. Giger, the Swiss artist and designer of Ridley Scott's Alien, has died, aged 74. Hans Rudolf 'Ruedi' Giger sustained injuries caused by a fall, Swiss newspaper Neue Zuercher Zeitung has reported (link in German — English summary available). The terrifying creature and sets he created for Ridley Scott's film earned him an Oscar for special effects in 1980. In the art world, Giger is appreciated for his wide body of work in the fantastic realism and surrealistic genres. Film work was just one of his talents. Giger is also known for his sculptures, paintings and furniture. The H.R. Giger Museum, inaugurated in the summer of 1998 in the Château St. Germain, is a four-level building complex in the historic, medieval walled city of Gruyères. It is the permanent home to many of the artist's most prominent works."

from the now-throw-some-money-at-openafs dept.
An anonymous reader writes "Red Hat announced their pending acquisition of Inktank this morning. Sage Weil and a team of researchers at University of California Santa Cruz first published the architecture in 2007. Sage joined DreamHost after college and continued development on Ceph until DreamHost spun off a Inktank, a company focused solely on Ceph. In Sage's blog post on the acquisition, he says 'In particular, joining forces with the Red Hat team will improve our ability to address problems at all layers of the storage stack, including in the kernel.' Sage goes on to announce that Inktank's proprietary management tools for Ceph will now be open sourced, citing Red Hat's pure open source development and business models.

Ceph has seen wide adoption in OpenStack customer deployments, alongside Red Hat's existing Gluster system."
Ceph looks pretty cool if you're doing serious storage: CERN has a 3 Petabyte "prototype" cluster in use now (Only tangentially related, but still interesting, is how CERN does storage in general).

Stung By File-Encrypting Malware, Researchers Fight Back 85

itwbennett (1594911) writes "When Jose Vildoza's father became the victim of ransomware, he launched his own investigation. Diving into CryptoDefense's code, he found its developers had made a crucial mistake: CryptoDefense used Microsoft's Data Protection API (application programming interface), a tool in the Windows operating system to encrypt a user's data, which stored a copy of the encryption keys on the affected computer. Vildoza and researcher Fabian Wosar of the Austrian security company Emsisoft collaborated on a utility called the Emsisoft Decrypter that could recover the encrypted keys. In mid-March Vildoza had launched a blog chronicling his investigation, purposely not revealing the mistake CryptoDefense's authors had made. But Symantec then published a blog post on March 31 detailing the error."

LHCb Confirms Existence of Exotic Hadrons 99

Posted by Soulskill
from the pushing-back-the-boundaries-of-physics dept.
An anonymous reader sends this news from CERN: "The Large Hadron Collider beauty (LHCb) collaboration today announced results that confirm the existence of exotic hadrons – a type of matter that cannot be classified within the traditional quark model. Hadrons are subatomic particles that can take part in the strong interaction – the force that binds protons inside the nuclei of atoms. Physicists have theorized since the 1960s, and ample experimental evidence since has confirmed, that hadrons are made up of quarks and antiquarks that determine their properties. A subset of hadrons, called mesons, is formed from quark-antiquark pairs, while the rest – baryons – are made up of three quarks. ... The Belle Collaboration reported the first evidence for the Z(4430) in 2008. They found a tantalizing peak in the mass distribution of particles that result from the decays of B mesons. Belle later confirmed the existence of the Z(4430) with a significance of 5.2 sigma on the scale that particle physicists use to describe the certainty of a result. LHCb reports a more detailed measurement of the Z(4430) that confirms that it is unambiguously a particle, and a long-sought exotic hadron at that. They analyzed more than 25,000 decays of B mesons selected from data from 180 trillion (180x10^12) proton-proton collisions in the Large Hadron Collider."

Australia Declares Homeopathy Nonsense, Urges Doctors to Inform Patients 408

Posted by Unknown Lamer
from the healing-crystals-considered-harmful dept.
jones_supa (887896) writes "Homeopathy is a 200-year-old form of alternative medicine based on the principle that substances that produce symptoms in a healthy person can be used to treat similar symptoms in a sick person. The National Health and Medical Research Council of Australia has officially declared that homeopathic remedies are useless for human health. The body today released a guide for doctors (PDF) on how to talk to their patients about the lack of evidence for many such therapies. Doctors will also be told to warn patients of possible interactions between alternative and conventional medicines. On top of that, the council has produced a 300-page draft report that reviews the evidence for homoeopathy in treating 68 clinical conditions. It concludes 'there is no reliable evidence that homoeopathy is effective for treating health conditions'.

Representing the opposite viewpoint, Australian Homeopathic Association spokesman Greg Cope said he was disappointed at the narrow evidence relied on by the NHMRC in its report. 'What they have looked at is systematic trials for named conditions when that is not how homeopathy works,' he said. Homeopathy worked on the principle of improving a person's overall health and wellness, and research such as a seven-year study conducted in Switzerland was a better measure of its usefulness, he added. There are about 10,000 complementary medicine products sold in Australia but most consumers are unaware they are not evaluated by the domestic medicines safety watchdog before they are allowed on the market."

Fake PGP Keys For Crypto Developers Found 110

from the who-you-say-you-are dept.
IamTheRealMike (537420) writes "In recent months fake PGP keys have been found for at least two developers on well known crypto projects: Erinn Clark, a Tor developer and Gavin Andresen, the maintainer of Bitcoin. In both cases, these PGP keys are used to sign the downloads for popular pieces of crypto software. PGP keys are supposed to be verified through the web of trust, but in practice it's very hard to find a trust path between two strangers on the internet: one reply to Erinn's mail stated that despite there being 30 signatures [attached to] her key, [the respondent] couldn't find any trust paths to her. It's also very unclear whether anyone would notice a key substitution attack like this. This leaves three questions: who is doing this, why, and what can be done about it? An obvious candidate would be intelligence agencies, who may be trying to serve certain people with backdoored binaries via their QUANTUMTHEORY man-in-the-middle system. As to what can be done about it, switching from PGP to X.509 code signing would be an obvious candidate. Both Mac and Windows support it, obtaining a forged certificate is much harder than simply uploading a fake PGP key, and whilst X.509 certs can be issued in secret until Google's Certificate Transparency system is fully deployed, finding one would be strong evidence that an issuing CA had been compromised: something that seems plausible but for which we currently lack any evidence. Additionally, bad certificates can be revoked when found whereas beyond making blog posts, not much can be done about the fake PGP keys."

As the Web Turns 25, Sir Tim Berners-Lee Calls For A Web Magna Carta 80

Posted by Unknown Lamer
from the dream-machines-realized dept.
Today marks the 25th anniversary of Tim Berners-Lee's "Information Management: A Proposal," containing the ideas that led to the World Wide Web. From its humble beginnings as a way to store linked documents at CERN to... well, you're reading this now. To celebrate, the W3C is encouraging people to post their birthday greetings. Quoting Tim Berners-Lee: "In the following quarter-century, the Web has changed the world in ways that I never could have imagined. There have been many exciting advances. It has generated billions of dollars in economic growth, turned data into the gold of the 21st century, unleashed innovation in education and healthcare, whittled away geographic and social boundaries, revolutionised the media, and forced a reinvention of politics in many countries by enabling constant two-way dialogue between the rulers and the ruled." Martin S. and JestersGrind both wrote in to note that Tim Berners-Lee is calling for the creation of a Web Magna Carta. Again Quoting Tim Berners-Lee "It's time for us to make a big communal decision," he said. "In front of us are two roads - which way are we going to go? Are we going to continue on the road and just allow the governments to do more and more and more control - more and more surveillance? Or are we going to set up a bunch of values? Are we going to set up something like a Magna Carta for the world wide web and say, actually, now it's so important, so much part of our lives, that it becomes on a level with human rights?" How has the rise of the web affected your life? Also check out the CERN line mode browser simulation of the first web site.

Physicists Test Symmetry Principle With an Antimatter Beam 106

Posted by samzenpus
from the what-does-it-look-like-over-there? dept.
Hugh Pickens DOT Com writes "Jon Butterworth has an interesting article at The Guardian about the idea of standpoint-independence in physics and the absence of 'privileged observers.' The ASACUSA experiment at CERN plans to make a beam of antimatter, and measure the energy levels as the beam travels in a vacuum, away from the magnetic fields and away from any annihilating matter. The purpose of the experiment is to test CPT (Charge/Parity/Time) inversion to determine if the universe would look the same if we simultaneously swapped all matter for antimatter, left for right, and backwards in time for forwards in time. In string theory for example it is possible to violate this principle so the ASACUSA people plan to measure those antihydrogen energy levels very precisely. Any difference would mean a violation of CPT inversion symmetry. Physicist Ofer Lahav has some interesting observations in the article about how difficult it is these days for physicists to develop independent points of view on cosmology. 'Having been surrounded by a culture in which communication is seen as generally a good thing, this came as a surprise to me, but it is a very good point,' writes Butterworth. 'We gain confidence in the correctness of ideas if they are arrived at independently from different points of view.'

A good example is the independent, almost simultaneous development of quantum electrodynamics by Richard Feynman, Julian Schwinger and Sin-Itiro Tomonaga. They all three had very different approaches, and Tomonaga in particular was working in wartime Japan, completely cut off from the others. Yet Freeman Dyson was able to prove that the theories each had provided for the quantum behavior of electrons and photons were not only all equally good at describing nature, but were all mathematically equivalent — that is, the same physics, seen from different points of view. Whether we are using thought experiments, antimatter beams, sophisticated instrumentation, or sending spaceships to the outer solar system, Butterworth says the ability for scientists to loosen the constraints of our own point of view is hugely important. 'It is also, I think, closely related to the ability to put ourselves into the place of other people in society and to perceive ourselves as seen by them — to check our privilege, if you like. Imperfect and difficult, but a leap away from a childish self-centeredness and into adulthood.'"

CERN Wants a New Particle Collider Three Times Larger Than the LHC 238

Daniel_Stuckey writes "Not content with the 27-kilometer-round Large Hadron Collider, researchers at CERN have their sights set on a new beast of a particle collider that could have a circumference of 80 to 100 kilometers. The nuclear research organization announced that it was hatching plans for an ambitious successor to the LHC with an international study called the Future Circular Colliders program, which will kick off with a meeting next week. The idea is to consider different hadron collider designs similar to the existing LHC but more powerful — much more powerful. CERN wrote it was looking for a collider 'capable of reaching unprecedented energies in the region of 100 TeV.' The existing LHC will reach a maximum of around 14 TeV."

Kansas Delays Municipal Broadband Ban 156

Mokurai writes with an update to a story from last week about legislation in Kansas that would have banned most municipal broadband, including the expansion of Google Fiber. Now, after the public backlash that erupted online, government officials have postponed the legislation's hearings, putting it on hold indefinitely. From the article: "Senate Bill 304 would prohibit cities and counties from building public broadband networks. The Commerce Committee, which [Sen. Julia Lynn] chairs, was scheduled to have a hearing Tuesday, but Lynn released a statement that hearings have been postponed indefinitely. 'Based on the concerns I heard last week, I visited with industry representatives and they have agreed to spend some time gathering input before we move forward with a public hearing,' Lynn said in a statement. 'We'll revisit the topic when some of these initial concerns have been addressed.' Lynn elaborated while exiting a Senate Judiciary hearing. The senator said she has instructed 'the parties' involved with the bill to address the public’s concerns. The bill was introduced by John Federico, a cable industry lobbyist."

China's PandaX Project Looks For Dark Matter In the Heart of a Marble Mountain 62

the_newsbeagle writes "Chinese engineers love their superlatives: Biggest dam, fastest train, etc etc. Now they've constructed the deepest underground dark matter detector beneath a mountain in Sichuan province. Such dark matter seekers have to be buried deep to shield them from cosmic rays, because that radiation would be picked up by the detector and could be confused for radiation generated by dark matter. Other dark matter detectors are similarly subterranean: LUX, in the United States, is at the bottom of an abandoned mine in South Dakota, and a European effort called XENON lies below the Gran Sasso mountain. The Chinese researchers hope their PandaX detector will finally reveal the much-hypothesized, never-seen dark matter particles known as WIMPs."

CERN Antimatter Experiment Produces First Beam of Antihydrogen 136

Posted by Soulskill
from the now-we-just-need-some-dilithium-crystals dept.
An anonymous reader writes "Matter and antimatter annihilate immediately when they meet, so aside from creating antihydrogen, one of the key challenges for physicists is to keep antiatoms away from ordinary matter. To do so, experiments take advantage of antihydrogen's magnetic properties (which are similar to hydrogen's) and use very strong non-uniform magnetic fields to trap antiatoms long enough to study them. However, the strong magnetic field gradients degrade the spectroscopic properties of the (anti)atoms. To allow for clean high-resolution spectroscopy, the ASACUSA collaboration developed an innovative set-up to transfer antihydrogen atoms to a region where they can be studied in flight, far from the strong magnetic field (scientific paper)."

A number of companies are either selling or preparing to sell 3-D scanners. Aside from fun (but interesting) uses, like duplicating chess pieces or possibly reproducing a miniature of Rodin's famous sculpture, Fallen Caryatid Carrying Her Stone, Matterform anticipates archeologists reproducing artifacts so that students can study them without handling the precious originals. This video is an interview with Matterform co-founder Drew Cox, who was exhibiting Matterform's scanner at CES 2014. MakerBot is also selling a scanner, as are a growing number of others. In fact, even though Matterform talks about being a low-cost (pre-order price $579) scanner for home use, as opposed to a commercial one that costs thousands. There are also several interesting hand-held scanners out there. Sense sells theirs for $399. Structure has one for $349 that's essentially a peripheral for an iPad. And this is just a random selection from a brief Google search. Use "3-D Scanner" as your search term and you'll find multiple Google pages full of 3-D scanners and information about them -- including software being developed at ETH zurich that turns your smartphone into a 3-D scanner.

While the 'DC Power Supply for Portable Personal Computer' doesn't have a legal mandate behind it, the IEC is still optimistic that it will lead to a reduction in electronics waste and make it easier to find a replacement charger. Unfortunately the technical documentation does not seem to be available yet, but previous comments indicate that it will be a barrel plug of some kind." I wish they'd push a yank-resistant and positive-connecting plug along the lines of Apple's MagSafe.
