Quantum Physics Just Got Less Complicated

Fri, 19/12/2014 - 15:59
wabrandsma sends this news from Phys.org: Here's a nice surprise: quantum physics is less complicated than we thought. An international team of researchers has proved that two peculiar features of the quantum world previously considered distinct are different manifestations of the same thing. The result is published 19 December in Nature Communications. Patrick Coles, Jedrzej Kaniewski, and Stephanie Wehner made the breakthrough while at the Center for Quantum Technologies at the National University of Singapore. They found that wave-particle duality is simply the quantum uncertainty principle in disguise, reducing two mysteries to one.

Hackers' Shutdown of 'The Interview' Confirms Coding Is a Superpower

Fri, 19/12/2014 - 15:16
theodp writes: The idea of programming as a superpower was touched upon by CS teacher Alfred Thompson back in 2010, but it became a rallying call of sorts for the Hour of Code after Dropbox CEO Drew Houston described coding as "the closest thing we have to a superpower" in a Code.org video that went viral. And if the kids who learned to code with the President last week were dubious about the power of coding, this week's decision by Sony to scrap the release of the satirical film The Interview after a massive hack attack should put aside any doubts, especially after new revelations that Sony had reached out to the White House for help and screened the film for administration officials back in June. White House press secretary Josh Earnest said Thursday that the Obama Administration is viewing the Sony attack as a "serious national security matter" and is considering a range of possible options as a response, which could turn things into a contest of U.S. Superpower vs. Coding Superpower. In case it wasn't mentioned last week, remember to always use your coding superpower for good, kids!

Researchers Discover SS7 Flaw, Allowing Total Access To Any Cell Phone, Anywhere

Fri, 19/12/2014 - 14:32
krakman writes: Researchers discovered security flaws in SS7 that allow listening to private phone calls and intercepting text messages on a potentially massive scale – even when cellular networks are using the most advanced encryption now available. The flaws, to be reported at a hacker conference in Hamburg this month, are actually functions built into SS7 for other purposes – such as keeping calls connected as users speed down highways, switching from cell tower to cell tower – that hackers can repurpose for surveillance because of the lax security on the network. It is thought that these flaws were used for bugging German Chancellor Angela's Merkel's phone. Those skilled at the housekeeping functions built into SS7 can locate callers anywhere in the world, listen to calls as they happen or record hundreds of encrypted calls and texts at a time for later decryption (Google translation of German original). There is also potential to defraud users and cellular carriers by using SS7 functions, the researchers say. This is another result of security being considered only after the fact, as opposed to being part of the initial design.

Skeptics Would Like Media To Stop Calling Science Deniers 'Skeptics'

Fri, 19/12/2014 - 13:50
Layzej writes: Prominent scientists, science communicators, and skeptic activists, are calling on the news media to stop using the word "skeptic" when referring to those who refuse to accept the reality of climate change, and instead refer to them by what they really are: science deniers. "Not all individuals who call themselves climate change skeptics are deniers. But virtually all deniers have falsely branded themselves as skeptics. By perpetrating this misnomer, journalists have granted undeserved credibility to those who reject science and scientific inquiry."

Scientists Discover That Exercise Changes Your DNA

Fri, 19/12/2014 - 13:07
HughPickens.com writes The human genome is astonishingly complex and dynamic, with genes constantly turning on or off, depending on what biochemical signals they receive from the body. Scientists have known that certain genes become active or quieter as a result of exercise but they hadn't understood how those genes knew how to respond to exercise. Now the NYT reports that scientists at the Karolinska Institute in Stockholm have completed a study where they recruited 23 young and healthy men and women, brought them to the lab for a series of physical performance and medical tests, including a muscle biopsy, and then asked them to exercise half of their lower bodies for three months. The volunteers pedaled one-legged at a moderate pace for 45 minutes, four times per week for three months. Then the scientists repeated the muscle biopsies and other tests with each volunteer. Not surprisingly, the volunteers' exercised leg was more powerful now than the other, showing that the exercise had resulted in physical improvements. But there were also changes within the exercised muscle cells' DNA. Using technology that analyses 480,000 positions throughout the genome, they could see that new methylation patterns had taken place in 7,000 genes (an individual has 20–25,000 genes). In a process known as DNA methylation, clusters of atoms, called methyl groups, attach to the outside of a gene like microscopic mollusks and make the gene more or less able to receive and respond to biochemical signals from the body. In the exercised portions of the bodies, many of the methylation changes were on portions of the genome known as enhancers that can amplify the expression of proteins by genes. And gene expression was noticeably increased or changed in thousands of the muscle-cell genes that the researchers studied. Most of the genes in question are known to play a role in energy metabolism, insulin response and inflammation within muscles. In other words, they affect how healthy and fit our muscles — and bodies — become. Many mysteries still remain but the message of the study is unambiguous. "Through endurance training — a lifestyle change that is easily available for most people and doesn't cost much money," says Sara Lindholm, "we can induce changes that affect how we use our genes and, through that, get healthier and more functional muscles that ultimately improve our quality of life."

Colorado Sued By Neighboring States Over Legal Pot

Fri, 19/12/2014 - 11:26
SternisheFan notes that Nebraska and Oklahoma are suing Colorado over marijuana legalization. The attorneys general of Nebraska and Oklahoma sued Colorado in the U.S. Supreme Court on Thursday, arguing state-legalized marijuana from Colorado is improperly spilling across state lines. The suit invokes the federal government's right to regulate both drugs and interstate commerce, and says Colorado's decision to legalize marijuana has been "particularly burdensome" to police agencies on the other side of the state line. In June, USA TODAY highlighted the flow of marijuana from Colorado into small towns across Nebraska: felony drug arrests in Chappell, Neb., just 7 miles north of the Colorado border have skyrocketed 400% in three years. "In passing and enforcing Amendment 64, the state of Colorado has created a dangerous gap in the federal drug control system enacted by the United States Congress. Marijuana flows from this gap into neighboring states, undermining plaintiff states' own marijuana bans, draining their treasuries, and placing stress on their criminal justice systems," says the lawsuit. "The Constitution and the federal anti-drug laws do not permit the development of a patchwork of state and local pro-drug policies and licensed distribution schemes throughout the country which conflict with federal laws."

Kepler Makes First Exoplanet Discovery After Mission Reboot

Fri, 19/12/2014 - 10:31
astroengine writes NASA's Kepler space telescope has detected its first new extrasolar planet after mission engineers were able to save the mission from a premature death after two of the exoplanet hunter's four stabilizing reaction wheels failed last year. Called "K2," the extended mission arose from an "innovative idea" that appears to have given the prolific telescope a new lease on life. "Last summer, the possibility of a scientifically productive mission for Kepler after its reaction wheel failure in its extended mission was not part of the conversation," said Paul Hertz, NASA's astrophysics division director at the agency's headquarters in Washington D.C. "Today, thanks to an innovative idea and lots of hard work by the NASA and Ball Aerospace team, Kepler may well deliver the first candidates for follow-up study by the James Webb Space Telescope to characterize the atmospheres of distant worlds and search for signatures of life."

Satellite Captures Glowing Plants From Space

Fri, 19/12/2014 - 03:02
sciencehabit writes About 1% of the light that strikes plants is re-emitted as a faint, fluorescent glow—a measure of photosynthetic activity. Today, scientists released a map of this glow as measured by the Orbiting Carbon Observatory-2, a NASA satellite launched in July with the goal of mapping the net amount of carbon in the atmosphere. The map reveals that tropical rainforests near the equator are actively sucking up carbon, while the Corn Belt in the eastern United States, near the end of its growing season, is also a sink. Higher resolution fluorescence mapping could one day be used to help assess crop yields and how they respond to drought and heat in a changing climate.

Investigation: Apple Failing To Protect Chinese Factory Workers

Fri, 19/12/2014 - 00:56
mrspoonsi writes with the findings of an investigation into working conditions at a factory that makes Apple products. Poor treatment of workers in Chinese factories which make Apple products has been discovered by an undercover BBC Panorama investigation. Filming on an iPhone 6 production line showed Apple's promises to protect workers were routinely broken. It found standards on workers' hours, ID cards, dormitories, work meetings and juvenile workers were being breached at the Pegatron factories. Apple said it strongly disagreed with the programme's conclusions. Exhausted workers were filmed falling asleep on their 12-hour shifts at the Pegatron factories on the outskirts of Shanghai. One undercover reporter, working in a factory making parts for Apple computers, had to work 18 days in a row despite repeated requests for a day off. Another reporter, whose longest shift was 16 hours, said: "Every time I got back to the dormitories, I wouldn't want to move. Even if I was hungry I wouldn't want to get up to eat. I just wanted to lie down and rest. I was unable to sleep at night because of the stress."

Critical Git Security Vulnerability Announced

Fri, 19/12/2014 - 00:13
An anonymous reader writes Github has announced a security vulnerability and has encourage users to update their Git clients as soon as possible. The blog post reads in part: "A critical Git security vulnerability has been announced today, affecting all versions of the official Git client and all related software that interacts with Git repositories, including GitHub for Windows and GitHub for Mac. Because this is a client-side only vulnerability, github.com and GitHub Enterprise are not directly affected. The vulnerability concerns Git and Git-compatible clients that access Git repositories in a case-insensitive or case-normalizing filesystem. An attacker can craft a malicious Git tree that will cause Git to overwrite its own .git/config file when cloning or checking out a repository, leading to arbitrary command execution in the client machine. Git clients running on OS X (HFS+) or any version of Microsoft Windows (NTFS, FAT) are exploitable through this vulnerability. Linux clients are not affected if they run in a case-sensitive filesystem....Updated versions of GitHub for Windows and GitHub for Mac are available for immediate download, and both contain the security fix on the Desktop application itself and on the bundled version of the Git command-line client."

Marissa Mayer's Reinvention of Yahoo! Stumbles

Thu, 18/12/2014 - 23:30
schnell writes The New York Times Magazine has an in-depth profile of Marissa Mayer's time at the helm of Yahoo!, detailing her bold plans to reinvent the company and spark a Jobs-ian turnaround through building great new products. But some investors are saying that her product focus (to the point of micromanaging) hasn't generated results, and that the company should give up on trying to create the next iPod, merge with AOL to cut costs and focus on the unglamorous core business that it has. Is it time for Yahoo! to "grow up" and set its sights lower?

Extracting Data From the Microsoft Band

Thu, 18/12/2014 - 22:30
An anonymous reader writes The Microsoft Band, introduced last month, hosts a slew of amazing sensors, but like so many wearable computing devices, users are unable to access their own data. A Brown University professor decompiles the app, finds that the data is transmitted to the Microsoft "cloud", and explains how to intercept the traffic to retrieve the raw minute-by-minute data captured by the Band.

"Team America" Gets Post-Hack Yanking At Alamo Drafthouse, Too

Thu, 18/12/2014 - 21:48
Slate reports that even old movies are enough to trigger a pretty strong knee jerk: Team America, World Police , selected as a tongue-in-cheek replacement by Dallas's Alamo Drafthouse Theater for the Sony-yanked The Interview after that film drew too much heat following the recent Sony hack, has also been pulled. The theater's tweet, as reprinted by Slate: “due to circumstances beyond our control,” their Dec. 27 Team America screening has also been canceled." If only I had a copy, I'd like to host a viewing party here in Austin for The Interview, which I want to see now more than ever. (And it would be a fitting venue.)

Grinch Vulnerability Could Put a Hole In Your Linux Stocking

Thu, 18/12/2014 - 20:51
itwbennett writes In a blog post Tuesday, security service provider Alert Logic warned of a Linux vulnerability, named grinch after the well-known Dr. Seuss character, that could provide attackers with unfettered root access. The fundamental flaw resides in the Linux authorization system, which can inadvertently allow privilege escalation, granting a user full administrative access. Alert Logic warned that Grinch could be as severe as the Shellshock flaw that roiled the Internet in September.

Ask Slashdot: What Can I Really Do With a Smart Watch?

Thu, 18/12/2014 - 20:10
kwelch007 writes I commonly work in a clean-room (CR.) As such, I commonly need access to my smart-phone for various reasons while inside the CR...but, I commonly keep it in my front pocket INSIDE my clean-suit. Therefore, to get my phone out of my pocket, I have to leave the room, get my phone out of my pocket, and because I have a one track mind, commonly leave it sitting on a table or something in the CR, so I then have to either have someone bring it to me, or suit back up and go get it myself...a real pain. I have been looking in to getting a 'Smart Watch' (I'm preferential to Android, but I know Apple has similar smart-watches.) I would use a smart-watch as a convenient, easy to transport and access method to access basic communications (email alerts, text, weather maps, etc.) The problem I'm finding while researching these devices is, I'm not finding many apps. Sure, they can look like a nice digital watch, but I can spend $10 for that...not the several hundred or whatever to buy a smart-watch. What are some apps I can get? (don't care about platform, don't care if they're free) I just want to know what's the best out there, and what it can do? I couldn't care less about it being a watch...we have these things called clocks all over the place. I need various sorts of data access. I don't care if it has to pair with my smart-phone using Bluetooth or whatever, and it won't have to be a 100% solution...it would be more of a convenience that is worth the several hundred dollars to me. My phone will never be more than 5 feet away, it's just inconvenient to physically access it. Further, I am also a developer...what is the best platform to develop for these wearable devices on, and why? Maybe I could make my own apps? Is it worth waiting for the next generation of smart-watches?

Australia Moves Toward New Restrictions On Technology Export and Publication

Thu, 18/12/2014 - 19:31
An anonymous reader writes Australia is starting a public consultation process for new legislation that further restricts the publication and export of technology on national security grounds. The public consultation starts now (a few days before Christmas) and it is due by Jan 30th while a lot of Australians are on holidays. I don't have the legal expertise to dissect the proposed legislation, but I'd like some more public scrutiny on it. I find particularly disturbing the phrase "The Bill includes defences that reverse the onus of proof which limit the right to be presumed innocent until proven guilty" contained in this document, also available on the consultation web site.

India Successfully Test Fires Its Heaviest Rocket

Thu, 18/12/2014 - 18:49
vasanth (908280) writes India on Thursday moved forward in rocket technology with the successful flight testing of its heaviest next generation rocket and the crew module . The 630-tonne three-stage rocket, Geo-Synchronous Satellite Launch Vehicle Mark III, carried active solid boosters, liquid core stage and a passive cryo stage and a crew module to test its re-entry characteristics. This rocket is capable of doubling the capacity of payloads India can carry into space and it can deposit up to four tonne class of communication satellites into space. India also plans to use this rocket for ferrying Indian astronauts into space. For India, ISRO (the Indian space agency) perfecting the cryogenic engine technology is crucial as India can save precious foreign exchange by launching heavy duty communication satellites by itself.
