Quasiparticles carry entanglement to near infinite speeds

crocus08 In a recent experiment, scientists were able to observe quasiparticles propagating across a string of ions, creating waves of quantum entanglement in their wake. Experiments like this one, which study systems with multiple quantum bodies, are crucial to learning about the behavior of quasiparticles and their interactions with more traditional particles. It’s tempting to think that quasiparticles are not particles at all. Quasiparticles are “objects” that emerge within a complex system, such as a solid object. The collective behavior of the particles in the solid can create the impression of a new particle. The impression—or quasiparticle—moves through the solid as if it were a real particle moving through empty space, and it behaves according to the same rules. Nevertheless, within their system, quasiparticles can have real effects on their environment. Most recently, scientists were able to track the propagation of quasiparticles called magnons through a collection of atoms. Now, scientists have been able to watch as that propagation changed the behavior of these atoms. And in the process, the quasiparticles reached speeds where a conventional model, which we use to understand time, breaks down. Read 13 remaining paragraphs | Comments

Why Google took years to address a battery-draining “bug” in Chrome

Aurich Lawson A recent Forbes report  says that Chrome on Windows uses up more battery than competing browsers, thanks to a high system timer setting. Unlike Linux or Mac OS X, Windows uses a timer to schedule tasks. At idle, the timer on Windows is set to about 15 ms, so if it has no work to do, it will go to sleep and only wake up every 15 ms to check if it needs to do something. Applications can change this timer, and other browsers like Firefox and Internet Explorer don’t mess with it until they need to do something processor intensive, like playing a video. After the video is done, the timer is set to return to 15 ms so that the computer can idle again. Chrome, though, boosts the timer to 1 ms and keeps it there forever. The difference means that on Firefox at idle, the CPU only wakes 64 times a second. On Chrome, it wakes up 1,000 times a second. In its Windows documentation, Microsoft notes that setting the system timer to a high value can increase power consumption by “as much as 25 percent.” This means that on a laptop, you’ll get a shorter runtime with Chrome than you will on a competing browser. And the issue has been around for a long time. Forbes links to a bug report documenting the problem that was first filed in 2010. Read 7 remaining paragraphs | Comments

Id shows off double-jumping, skull-crushing new Doom at QuakeCon

If you weren’t at QuakeCon, this content-free teaser is all you get to see of the new Doom for the time being. The bad news is that only people who were actually at Dallas’ QuakeCon last night were able to see the world-premiere gameplay footage from the next Doom game, which somehow hasn’t been leaked online yet. The good news is that plenty of people that were there are reporting on the unveiling, which seemed to include a number of extremely un- Doom -like additions. One of the bigger changes brought by the new Doom (which is notably not being called Doom 4 anymore ) is a jet-pack powered double-jump, à la Crysis 3 , Titanfall , Destiny and, now, presumably, every first-person shooter to come out in the next year or two. Players can also climb up the sides of “large crates and gaps” according to PC Gamer’s report , adding even more ability to go vertical. But it’s the Mortal Kombat -style melee finishing moves that seem to have gotten the crowd the most riled up. PC Gamer describes how, once an enemy is low on health, the player can get close and activate moves that see “lower jaws pulled off, skulls stomped on, and hearts torn out with the level of detail usually reserved for those slow-mo bullet cams in the Sniper Elite series.” Rock Paper Shotgun noted  that “enemies break apart like moldy bread… literally tearing them in half sometimes.” The outlet also reported scenes with “crushing heads, chunks flying everywhere.” Read 3 remaining paragraphs | Comments

Verizon’s Accidental Mea Culpa

Barryke writes: Verizon has blamed Netflix for the streaming slowdowns their customers have been seeing. It seems the Verizon blog post defending this accusation has backfired in a spectacular way: The chief has clearly admitted that Verizon has capacity to spare, and is deliberately constraining throughput from network providers. Level3, a major ISP that interconnects with Verizon’s networks, responded by showing a diagram that visualizes the underpowered interconnect problem and explaining why Verizon’s own post indicates how it restricts data flow. Level3 also offered to pay for the necessary upgrades to Verizon hardware: “… these cards are very cheap, a few thousand dollars for each 10 Gbps card which could support 5, 000 streams or more. If that’s the case, we’ll buy one for them. Maybe they can’t afford the small piece of cable between our two ports. If that’s the case, we’ll provide it. Heck, we’ll even install it.” I’m curious to see Verizon’s response to this straightforward accusation of throttling paying users (which tech-savvy readers were quick to confirm).

Point-of-Sale System Bought On eBay Yields Treasure Trove of Private Data

jfruh writes: Point-of-sale systems aren’t cheap, so it’s not unusual for smaller merchants to buy used terminals second-hand. An HP security researcher bought one such unit on eBay to see what a used POS system will get you, and what he found was disturbing: default passwords, a security flaw, and names, addresses, and social security numbers of employees of the terminal’s previous owner.

After 150 Years, Scientists Finally Know How Barnacle Glue Works

Over a century and a half ago, Charles Darwin first described the remarkable adhesive capabilities of barnacles. He couldn’t figure out how their natural superglue worked, though. And it took until now to finally unlock the barnacle glue’s mysteries . Read more…

Faulty red light cameras produced thousands of bogus traffic tickets

At least 13,000 Chicago motorists have been cited with undeserved tickets thanks to malfunctioning red-light cameras, according to a 10-month investigation published Friday by the Chicago Tribune . The report found that the $100 fines were a result of “faulty equipment, human tinkering or both.” According to the investigation: Cameras that for years generated just a few tickets daily suddenly caught dozens of drivers a day. One camera near the United Center rocketed from generating one ticket per day to 56 per day for a two-week period last summer before mysteriously dropping back to normal. Tickets for so-called rolling right turns on red shot up during some of the most dramatic spikes, suggesting an unannounced change in enforcement. One North Side camera generated only a dozen tickets for rolling rights out of 100 total tickets in the entire second half of 2011. Then, over a 12-day spike, it spewed 563 tickets—560 of them for rolling rights. Many of the spikes were marked by periods immediately before or after when no tickets were issued—downtimes suggesting human intervention that should have been documented. City officials said they cannot explain the absence of such records. City officials and Redflex Traffic Systems of Arizona, the report said, “acknowledged oversight failures and said the explosions of tickets should have been detected and resolved as they occurred. But they said that doesn’t mean the drivers weren’t breaking the law, and they defended the red light camera program overall as a safety success story. The program has generated nearly $500 million in revenue since it began in 2003.” Read 1 remaining paragraphs | Comments

New Treatment Stops Type II Diabetes

multicsfan writes Researchers have found that an injection of protein FGF1 stops weight induced diabetes in mice, with no apparent side effects. However, the cure only lasts 2 days at a time. Future research and human trials are needed to better understand and create a working drug. From the story: “The team found that sustained treatment with the protein doesn’t merely keep blood sugar under control, but also reverses insulin insensitivity, the underlying physiological cause of diabetes. Equally exciting, the newly developed treatment doesn’t result in side effects common to most current diabetes treatments.” Read more of this story at Slashdot.

Google Maps for mobile now helps bikers avoid steep hills

Summer’s in full swing and the weather’s nice, so how about ditching your gas-guzzlin’ ride for something human-powered? If you do, Google’s latest update to Maps on mobile wants to help make biking a little easier . New features for two-wheeled transportation include routes based on elevation so you can avoid any strenuous climbs and, as Android Police reports , there’s apparently a tool to compare different itineraries based on elevation as well. Should you to stick to a car for getting around (air conditioning is awfully nice), Mountain View didn’t forget about you, either. A handful of voice commands have been added for checking what traffic is like ahead of you, estimated arrival time and next-turn reminders, among others. Unlike the familiar “OK, Google” voice-prompt though, these orders aren’t fully hands-free just yet. Meaning, we don’t recommend searching for the on-screen microphone button to initiate the app’s listening mode while you’re in traffic — fumbling to activate a route overview isn’t worth causing an accident over. If you want to take the app for a test-drive, however, check out the source link .
