Instant Quantum Communication Is Near 287

Posted by timothy from the by-the-time-you-read-this dept.
fljmayer writes "In this experiment, researchers in Australia and Japan were able to transfer quantum information from one place to another without having to physically move it. It was destroyed in one place and instantly resurrected in another, 'alive' again and unchanged. This is a major advance, as previous teleportation experiments were either very slow or caused some information to be lost."

Fermi Lab May Have Discovered New Particle or Force 226

Posted by samzenpus from the probably-a-build-up-of-midichlorians dept.
schleprock63 writes "Physicists at Fermi Lab have found a 'suspicious bump' in their data that could indicate they've found a new elementary particle or even a new force of nature. The discovery could 'be the most significant discovery in physics in half a century.' Physicists have ruled out that the particle could be the standard model Higgs boson, but theorize that it could be some new and unexpected version of the Higgs. This discovery comes as the Tevatron is slated to go offline sometime in September."

Hurt Locker File-Sharing Subpoenas Begin 376

Posted by Soulskill from the how-not-to-generate-good-press dept.
In May we discussed news that producers of the film The Hurt Locker filed a lawsuit against 5,000 John Does, known only by their IP addresses at the time, for sharing the movie over peer-to-peer sites. Now, reader suraj.sun notes that subpoenas for the lawsuit are finally going out. "Qwest Communications on Monday notified a customer in Denver that the Internet service provider has received a subpoena from lawyers representing Voltage Pictures, the production company that made The Hurt Locker. ... In legal documents, Voltage Pictures has blamed the movie's relatively poor domestic performance on illegal file sharing. As of March 21, the movie had grossed $16 million domestically, but took in $40 million overall. According to reports, the film's production budget was $15 million. The film leaked to the Web five months before the movie's US debut. ... For allegedly downloading The Hurt Locker, DGW told the Qwest customer from Denver that settling the case early would cost $2,900, according to documents reviewed by CNET."

Study Shows People In Power Make Better Liars 265

Posted by Soulskill from the practice-makes-perfect dept.
oDDmON oUT writes "MSNBC is reporting that a Columbia Business School study shows those who hold power over others make better liars. According to one of the study's coauthors, 'It just doesn't hurt them as much to do it.' For the average liar, she said, the act of lying elicits negative emotions, physiological stress and the fear of getting caught in a lie. As a result, she added, liars will often send out cues that they are lying by doing things like fidgeting in a chair or changing the rate of their speech. But for the powerful, the impact is very different: 'Power, it seems, enhances the same emotional, cognitive, and physiological systems that lie-telling depletes. People with power enjoy positive emotions, increases in cognitive function, and physiological resilience such as lower levels of the stress hormone cortisol. Thus, holding power over others might make it easier for people to tell lies.'"

Software To Diagnose Faulty PC Hardware? 274

Posted by timothy from the diagnostics-are-underrated dept.
Etylowy writes "Over the years I have repaired my own PC and those belonging to family and friends many, many times. While in most cases it turned out to be restoring a system after malware/the user/Windows made a mess, or simple cases of 'follow the smell of smoke and molten plastic,' there were some nasty ones where the computer mostly works. By 'mostly,' I mean: you can boot it up, it might even work for a while, but will crash way too often to blame it all on Microsoft — what do you do then? Once you strip it of any extra hardware (which, with today's motherboards that have pretty much everything integrated, might not be an option) you are left with the CPU, motherboard, graphics card, RAM and HDD. You can test the HDD, you can run memtest86+ to check the RAM, but how do you go about testing the CPU, motherboard and graphics card trio to find which is to blame? Replacing them one by one isn't really an option. Do you know of any software that would help the way memtest helps with RAM?"

The Mindset of the Incoming College Freshmen 383

Posted by kdawson from the we-have-always-lived-in-the-castle dept.
Beloit College has come out with its annual Mindset List of what the incoming class (of 2013) has always known and has never known. "For these students, ... the Green Giant has always been Shrek, not the big guy picking vegetables. They have never used a card catalog to find a book. ... Tattoos have always been very chic and highly visible. ... Rap music has always been mainstream. ... Except for the present incumbent, the President has never inhaled. ... Amateur radio operators have never needed to know Morse code."

Soccerbots Learn How To Fall Gracefully 105

Posted by samzenpus from the I've-fallen-and-I-can't-compute dept.
wjousts writes "Up until now, most work with humanoid robotics has focused on keeping them upright and balanced, but in the real world, falling down is inevitable. So now researcher in Chile are looking at teaching their Soccerbots how to fall down gracefully to minimize damage and allow for a quick recovery. According to a New Scientist article, 'They found that one of the main ways to minimise damage is for the robot to fold its legs underneath it. Among other things, that means the robot is much less likely to hit its head on the ground. Another good strategy is to use a fall sequence consisting of several movements, so the falling body has several points of contact with the ground, spreading the energy of the impact over a large number of joints, rather than taking it all in one disastrous crunch.'"

Wolfram's 2,3 Turing Machine Not Universal 284

Posted by kdawson from the whoa-not-so-fast-there-big-fella dept.
Fishbat writes "In a cutting message to the Foundations of Mathematics mailing list, Stanford's Vaughan Pratt has pointed out an elementary mistake in the recently announced proof that Wolfram's (2,3) machine is universal." Update: 10/30 04:18 GMT by KD : Ed Pegg Jr. from Wolfram Research points to this response to Dr. Pratt's note, which has been submitted to the FoM mailing list but has not yet appeared there due to moderation.

Spontaneous Brain Activity and Human Behavior 141

Posted by Zonk from the argh-me-precious-brains dept.
Dr. Eggman writes "Ars Technica is featuring an article summarizing an interesting and perhaps controversial paper which finds links between spontaneous brain activity and human behavior. Spontaneous, yet organized brain activity has been observed without stimulation and even in humans under anesthesia. This paper attempts to link this activity to the observed variability of human performance in even simple, repeated tasks, hoping to establish a new avenue of research into alternative brain processing theories. 'The subtraction provided a much cleaner connection between the button press and brain activity in the left SMC. Once spontaneous activity was accounted for, noise was down by 60 percent, and the signal to noise ratio in the experiments doubled. Putting this another way, spontaneous activity accounted for about 60 percent of the variation between tests. The authors say that these results show that spontaneous brain activity is more than simply a physiological artifact; it helps account for some of the variability in human behavior. In that sense, they argue for a greater acceptance of the view that our brain may have some intrinsic activity that's somewhat independent of sensory input.'"

Comment Re:They should redefine a kilogram (Score 2, Insightful) 546

I agree, redefine...but it seems easier to redefine it by fixing Avogadro's number and then saying that the mass of one mole of C12 divided by 12 equals one gram.

Maybe to a physicist/mathematician it seems inelegant to base the definition of mass on an arbitrary number (Avogadro's) rather than on a physical constant. But are we absolutely, positively sure that physical constants are constant throughout the space-time continuum and that we've got them exactly right?

One Species' Genome Discovered Inside Another's 224

Posted by Zonk from the it's-a-mad-house-a-mad-house dept.
slyyy writes "The Universtiy of Rochester has discovered the complete genome of a bacterial parasite inside the genome of the host species. This opens the possibility of exchanging DNA between unrelated species and changing our understanding of the evolutionary process. From the article: 'Before this study, geneticists knew of examples where genes from a parasite had crossed into the host, but such an event was considered a rare anomaly except in very simple organisms. Bacterial DNA is very conspicuous in its structure, so if scientists sequencing a nematode genome, for example, come across bacterial DNA, they would likely discard it, reasonably assuming that it was merely contamination--perhaps a bit of bacteria in the gut of the animal, or on its skin. But those genes may not be contamination. They may very well be in the host's own genome. This is exactly what happened with the original sequencing of the genome of the anannassae fruitfly--the huge Wolbachia insert was discarded from the final assembly, despite the fact that it is part of the fly's genome.'"

GTA IV Trailer Released, Slows Sites 127

Posted by Zonk from the grand-theft-trailer dept.
Mr_Congeniality writes "The much-anticipated trailer for the next chapter in the Grand Theft Auto series has been released. Rockstar's servers, including the one that hosts Rockstar's homepage, was completely overloaded with traffic last night as a result. Users desperately flocking to other websites like GTANet and GTA4.net, but even these websites were overloaded by the interest level. If these sites are still slow, try GameTrailers or GameVideos as an alternative. For analysis of the video, CVG has ten things you may have missed, while 1up's editors offer their opinions on what they saw."
