Apple says Do Not Disturb scheduling is broken until January 8

After reports that iOS 6’s new Do Not Disturb feature stopped resetting according to schedule on New Year’s Day, Apple says scheduling won’t work until next Tuesday, January 8. The Do Not Disturb feature was added to iOS 6 in order to silence what might otherwise be distracting notifications, like those during a meeting or while sleeping. Users can manually turn Do Not Disturb on or off, or can set a scheduled time for Do Not Disturb to kick in automatically and then reset later. For instance, many users set Do Not Disturb to turn on around bedtime and reset the following day. However, users discovered on January 1 that Do Not Disturb did not automatically reset as scheduled. Furthermore, after manually resetting, it wouldn’t engage as scheduled that evening. Read 2 remaining paragraphs | Comments

World’s Longest High-Speed Rail Line Opens In China

An anonymous reader writes “Today China continued rolling out the future of high speed rail by officially unveiling the world’s longest high-speed rail line — a 2,298-kilometer (1,428-mile) stretch of railway that connects Beijing in the north to Guangzhou in the south. The first trains on the new route hit 300 kph (186 mph), cutting travel time between the two cities by more than half.” Read more of this story at Slashdot.

Earthworm guts become factory for nanoparticles

Enlarge / Meet the latest quantum dot assembly factory. Colorado State Quantum dots are nanoscale-sized pieces of semiconductor. Their small size ensures that quantum effects, like the Pauli exclusion principle, influence the behavior of electrons within them. This gives the dots properties that a bulk material with the same composition lacks, and it makes them appealing candidates for things like tiny lasers, photovoltaic materials, and LEDs. Another area where they’ve shown promise is medical imaging. In terms of absorbing and emitting light, quantum dots behave much like the fluorescent molecules we can use to label cells of interest. But, since their fluorescent properties depend on the shape of the particles rather than the chemical structure of a molecule, they are much less prone to undergoing reactions that destroy their fluorescence. The problem is that most semiconductors aren’t especially biocompatible, meaning additional chemical reactions need to be performed before the dots can attach to or enter cells. Some researchers have started to look towards making the dots in biological systems, figuring that the output would necessarily be biocompatible. After some successes with bacteria and yeast, they’ve moved on to a larger target: the earthworm. And it appears to work very well. Read 6 remaining paragraphs | Comments

The New Ethanol Blend May Damage Your Vehicle

Hugh Pickens writes writes “About 80 percent of the gasoline consumed in the U.S. is blended with ethanol, primarily with a 10 percent mix of ethanol, generally derived from corn. Now Kate Sheppard writes that the Environmental Protection Agency has approved a new policy that will allow states to raise the blend to up to 15 percent ethanol (also known as E15), approved for use for cars and light trucks from the model year 2001 and later. A few weeks ago, AAA issued a statement saying that the EPA’s new policy creates the ‘strong likelihood of consumer confusion and the potential for voided warranties and vehicle damage.’ AAA surveyed vehicle manufacturers, and found that only about 12 million of the 240 million vehicles on the roads today are built to use E15 gasoline. The EPA will require that gas pumps with E15 bear a warning sign noting the blend and that it is not recommended for cars older than the 2001 model year. But what happens if you accidentally use it? ‘Nobody really knows what negative effects [E15 is] going to have on the vehicle,’ says Brian Lyons, Toyota’s safety and quality communications manager. ‘We think that there needs to be a lot more study conducted to make sure there are no longer term effects on the vehicle. So far everything we’ve seen says there will be.’ The concern is that repeated, long-term exposure could cause the higher-alcohol-content fuel to degrade engine parts like valves and cylinder heads — which could potentially cost thousands of dollars to replace. Gas station owners don’t like it very much either, because they’d likely have to upgrade their equipment to use it. Nor are environmental groups big fans of the EPA’s decision arguing that increasing the use of ethanol can drive up food prices, and isn’t the best means of reducing our reliance on foreign fuels. The ethanol lobby is the only group that really seems to like the new rule. ‘We’ve force fed a fuel into every American’s car that benefits a few thousand corn farmers and ethanol refiners at the expense of virtually every other American,’ says Scott Faber.” Read more of this story at Slashdot.

“Neuristor”: Memristors used to create a neuron-like behavior

A cartoon showing spikes of activity traveling among neurons. UC Berkeley Computing hardware is composed of a series of binary switches; they’re either on or off. The other piece of computational hardware we’re familiar with, the brain, doesn’t work anything like that. Rather than being on or off, individual neurons exhibit brief spikes of activity, and encode information in the pattern and timing of these spikes. The differences between the two have made it difficult to model neurons using computer hardware. In fact, the recent, successful generation of a flexible neural system required that each neuron be modeled separately in software in order to get the sort of spiking behavior real neurons display. But researchers may have figured out a way to create a chip that spikes. The people at HP labs who have been working on memristors have figured out a combination of memristors and capacitors that can create a spiking output pattern. Although these spikes appear to be more regular than the ones produced by actual neurons, it might be possible to create versions that are a bit more variable than this one. And, more significantly, it should be possible to fabricate them in large numbers, possibly right on a silicon chip. The key to making the devices is something called a Mott insulator. These are materials that would normally be able to conduct electricity, but are unable to because of interactions among their electrons. Critically, these interactions weaken with elevated temperatures. So, by heating a Mott insulator, it’s possible to turn it into a conductor. In the case of the material used here, NbO 2 , the heat is supplied by resistance itself. By applying a voltage to the NbO 2 in the device, it becomes a resistor, heats up, and, when it reaches a critical temperature, turns into a conductor, allowing current to flow through. But, given the chance to cool off, the device will return to its resistive state. Formally, this behavior is described as a memristor. Read 4 remaining paragraphs | Comments

This Laser Weapon Got Five Times More Powerful in Just One Year

The pace of High Energy Laser (HEL) technology has become a sprint with nations and defense firms alike racing to develop more and more powerful systems. Nowhere is this breakneck pace clearer than at Rheinmetall’s Ochsenboden Proving Ground, especially during a recent test of the company’s shiny, new, 500-percent improved HEL anti-artillery platform.

Deformed skulls discovered in 1,000-year-old Mexican cemetery

Archaeologists digging in a 1,000-year-old pre-Hispanic cemetery in Mexico’s South Sonora have uncovered a series of skeletons featuring signs of cranial deformation. The practice, which is well documented among Mesoamerican peoples, has never been seen this far north before — a strong indication that their cultural influence was far more prominent than previously assumed.

Anonymous sets sights on an old enemy—the Westboro Baptist Church

That link? It leads to a survey entitled, “Interactive Butthurt Report v. 2.0.” Nothing is beneath the Westboro Baptist Church, as evidenced by the group’s announcement to picket outside Sandy Hook Elementary School in wake of the recent tragedy. The group’s most recent, perhaps most deplorable decision has apparently irked one of its oldest enemies : infamous hacker collective Anonymous. In response to the WBC’s plans early today, Anonymous tweeted , “It’s so nice of #WBC to provide the internet with a list of their twitter handles…” Roughly one hour later, they revealed their plans for the WBC : “#WBC GodHatesFags Site Admin gets #DOX’d via: Anonymous.” DOX, of course, refers to the work Anonymous did to find and publish a list of WBC members complete with e-mails, phone numbers, and even home addresses—all for the adoring public to access. In addition to the DOXing, Anonymous has repeatedly promoted a whitehouse.org petition to have the WBC recognized legally as a hate-group . The petition was created on Friday and it has already doubled the required 25,000 signatures. Read 1 remaining paragraphs | Comments

Google phasing out ActiveSync push mail for free customers

Calling it “Winter cleaning,” Google has announced that from January 30, 2013, users of Google Mail, Calendar, and Contacts will no longer receive Exchange ActiveSync (EAS) support on their accounts. EAS provides push mail and synchronization of contacts and calendars to a number of mobile platforms, including iOS, Symbian, and Windows Phone. It’s also one of the protocols that Windows 8’s Metro Mail app uses, as does Outlook 2013. Currently, users of Google’s services can enable EAS support to use their Google accounts with suitable devices. After the cut off, existing users will continue to be able to use EAS with their devices, but those users won’t be able to add new devices. All future devices will have to use IMAP for their mail, CalDAV for calendar sync, and CardDAV for contact sync. Android and iOS users can use these protocols, but many others will be left high and dry. Push mail, in particular, could be left behind, as many platforms (including iOS) don’t support the IMAP IDLE push mail feature. Read 4 remaining paragraphs | Comments

How to bring down mission-critical GPS networks with $2,500

Enlarge / The phase-coherent signal synthesizer with its top cover removed. The $2,500 device can be used to severely disrupt mission-critical GPS equipment used by the military and private industry. Nighswander et al. Scientists have devised a series of novel and inexpensive attacks that can severely disrupt mission-critical global positioning systems relied on by the military and a variety of industrial players, including airlines, mining companies, and operators of hydroelectric plants and other critical infrastructure. Unlike previous GPS attacks, the one developed by a team of scientists from Carnegie Mellon University and a private navigation company exploits software bugs in the underlying receivers. That allows the attacks to be stealthier and more persistent than earlier exploits, which primarily relied on signal jamming and spoofing. Prototype hardware that cost only $2,500 to build is able to cause a wide variety of GPS devices within a 30 mile radius to malfunction. Because many of those devices are nodes on special networks that make GPS signals more precise, the attacks have the effect of disrupting larger systems used in aviation, military, and critical infrastructure. The PCSS, or phase-coherent signal synthesizer, that they developed simultaneously receives and transmits civil GPS signals. It carries out many of the same things done by spoofers used in earlier GPS attacks. But instead of merely providing false information designed to compromise the accuracy of the GPS readings, it includes data that exploits weaknesses in the firmware of nearby receivers, many of which use the Internet to share their readings with other machines. The success of the PCSS is the result of an almost complete lack of authentication in the devices that send and receive GPS signals. Read 11 remaining paragraphs | Comments
