The American Workday, By Profession

parallel_prankster Re:Seems good to me. (146 comments)

This COULD be a bad thing. A good economy is one that maximizes productivity while helping workers find a work-life balance. If this trend continues, soon we are going to see an increase in the number of people with illnesses related to stress/fatigue etc. Besides, it could also be due to the fact that american workers have lesser bargaining power than workers in other nations. Again, I am not saying all of this is all good or bad. There are obvious benefits with our capitalist economy as well. Just that we need a good balance between approaches and currently, we are little outside of average, that's all. Whether that average is the right balance point, no one knows.

More Quantum Strangeness: Particles Separated From Their Properties

parallel_prankster Re:Can we dumb it down some more? (144 comments)

This is what I understood. They first split the beams into upper and lower paths and filtered out the neutrons from the lower path using their spin state . They double checked this by using limiting/filtering neutrons on one of the paths each time and measuring the number of neutrons after re-combining and filtering out the lower path. This way they made sure that the neutrons coming out after re-combining and filtering must have taken the upper path. Then they applied magnetic field on both paths. But it seems like the neutrons which supposedly could only have come from the upper path had been affected by magnetic field from the lower path. This implies as if their "positions/mass" took one path while their spin took another?

Supreme Court Rules Against Aereo Streaming Service

I fail to understand how this is a violation of copyright if really what Aereo is doing is capture OTA signals and recording them for their users. I mean anyone can do that for their own personal use anyway! The signals are free right? Its not like they were unscrambling and distributing TWC or Comcast signals.

I did not RTFA in depth but I am surprised that they did not have a mechanism to fix it remotely via updates of something. In these kinda devices you have to always assume there will be a failure and there should be a backup mechanism to be able to do quick updates. Think/develop it like the Curiosity the moon rover. There is no possibility of re-call and fix must be made really quick.

Virtual Boss Keeps Workers On a Short Leash

parallel_prankster Old article. Product is not all useless (664 comments)

I am surprised no one has said this so far. The earliest link for this is from 2007 - www.techdigest.tv/2007/06/hitachis_new_bu.html This product seem to be here - www.hitachi.com/design/field/solution/microscope/ It will become obviously illegal in many countries for companies to force your employees to wear this so I dont think what the above CNN article mentions is what this product will be advertised for at all. It is not a bad idea, I just think the scope of privacy abuse is huge. So, I think, one way this product could be used is by making it optional for people and making them aware of all the things it is recording. I mean, either have a turn off button or a way for you to leave it at your desk. I can see that this is a good way to measure which organizations within a company talk to which ones. It wont help in tele-conferences etc, it can add to that data though.

Ask Slashdot: How Can I Improve My Memory For Study?

parallel_prankster What I have done for this (384 comments)

I have a similar issue with not being able to sleep and not being able to focus on the task at hand thus taking much longer to finish things and for me it boiled down to the following 1) Get your body clock in order. Sleep and eat at fixed times as much as possible. Also, rest plentifully throughout the day 2) Eat the correct kind of food like fruits etc. Eating fast food for me has caused havoc on my stomach thus leading to sleep issues. Also, I reduced my sugar/candy/soda intake a lot. 3) Exercise. This is right up there with eat and sleep. 4) I realized that I was not finishing tasks because on some level I was not really interested in doing them. This you need to just do some thinking on what your goals are and are you really interested in doing what you are doing etc. 5) I also realized that I wasn't doing fun things enough that I would then be able to do my mundane work items. So on a daily or maybe at least weekly basis, participate in a fun/hobby activity. It is very refreshing. I am planning to buy a PS4 or XBOX for this soon. 6) I find that blocking out external noises and stimuli while working helps me focus on things. This along with making a log of what I am doing (learning Emacs org mode for this) helps me remember things much better. I bought noise cancelling headphones and turn off most notifications that are not important to me during the day as much as possible. 7) Most importantly, I realized focus/concentration is not something you build in a day or week. It takes a lot of time. It is literally like developing a muscle. You need to feed it right and work hard on it to sharpen it. Remember, you need a lifestyle change, not a quick fix. There is a lot of interest recently in mindfulness you can take a look at that. Hope this helps.

So, I understand that what the article is trying to say in terms of Chemistry. Basically, these storms could provide both the raw materials and the energy required to create biotic molecules. My question though is at what point those molecules become alive? When do they start reproducing or even get the will/understanding the need to reproduce/split to survive? How does that transformation occur that takes this energy from lightning or whatever and converts it to life?

Study Shows Professors With Tenure Are Worse Teachers

parallel_prankster Interest in Teaching Related to tenure? (273 comments)

I am not completely in agreement with this study. I only read the Atlantic article, I did not read the study so maybe I missed something. From what I have observed, the younger teachers who were on tenure track in universities were always more focused on getting research grants because that is what helped them get tenure. The older ones were more likely to win best teacher awards. From my just my personal experience of 8 years in grad school I feel like it is just the enthusiasm that some younger teachers show that is infectious and makes you feel like the teacher is good. The older teachers are actually better at drilling down concepts however they were less excited about the material and somehow that transferred to the students as well. Students were more likely to feel bored in their classes. I was a TA and that was a frequent complaint about my advisor but I used to go throw his material and it was fantastic. That said there was one tenured professor who was an okay teacher but left the teacher survey on the last day of classes, on our desks, on the way out muttering "Write whatever you want, nothing can happen to me."

Scientists Link Autism with Lack of Gut Bacteria

parallel_prankster parallel_prankster writes  |  about a year ago

parallel_prankster (1455313) writes "Scientists at University College Cork (UCC) have found that mice who were raised without bacteria in their gut showed autistic patterns of behavior. Scientists argue that their findings demonstrate the crucial role stomach bacteria plays in the development of normal social behaviour. Professor Ted Dinan, psychiatry professor and a principal investigator in the Alimentary Pharmabiotic Centre (APC), said the core of their paper argued that animals need a normal range of bacteria in their gut in order for normal social development. Dinan said, “In our studies involving mice, we found animals raised in a germ-free environment (without microbiota in their gut) spent more time interacting with objects than other animals and so have distinctively autistic patterns of behavior.”
He said that the serotonin system, which helps regulate mood, does not develop properly if there is not enough bacteria in the gut. Mice in the study who did not have enough bacteria were less interested in new social situations than mice with a normal level of bacteria.
The scientists said that the bacteria deficient mice behavior resembles social cognition deficits of patients. Children with autism also show repetitive behaviors and scientists pointed out that gut problems are common among those with autism. Scientists weaned bacteria and then added it and this reversed the mice’s social avoidance and repetitive behaviors, but had no impact on social cognition impairments."

Amazon Sells Out Predator Drone Toy After Mocking Reviews

Maisto International Inc.’s model Predator drones are selling out on Amazon.com Inc.’s website as parody reviews highlight how the toys can help children hone killing skills, mocking a controversial U.S. practice. The toy is a replica of the RQ-1 Predator, an unmanned aircraft that the U.S. Air Force has used in combat over Afghanistan, Pakistan, Serbia, Iraq and Yemen, according to the product description on Amazon. Only one of the $49.99 military-style toy jets is available for purchase on Amazon’s site, which is brimming with assessments laced with dark humor. “You can’t spell slaughter without laughter,” one pithy joker wrote.
        While Facebook and Twitter have always been more prominent forums for political satire, consumers have flocked to Amazon’s review section before. In October, the user comment section of an Avery Dennison Corp. binder listed on the e- commerce site became the subject of a similar outbreak. Reviewers used Amazon to make light of a comment made by then- Republican presidential nominee Mitt Romney during a debate. Amazon’s conditions of use posted on its website say that the Seattle-based company reserves the right to remove or edit reviews, which it doesn’t regularly examine. So far the reviews have not been removed."

Souped-up Immune Cells Force Leukemia into Remission

parallel_prankster parallel_prankster writes  |  about a year and a half ago

parallel_prankster (1455313) writes "Augmented immune cells have made an impressive impact on the survival of people with leukemia. Thirteen people with a form of the cancer called multiple myeloma were treated with genetically engineered T-cells, and all improved. Cancers often develop because T-cells have lost their ability to target tumour cells, which they normally destroy. To retune that targeting, a team led by Aaron Rapoport at the University of Maryland in Baltimore engineered T-cell genes that coded for a receptor on the cell's surface. They extracted T-cells from each person, then inserted the engineered genes into these cells and re-injected them. The souped-up cells were better able to recognise proteins called NY-ESO-1 and LAGE-1, found on myeloma cells but not healthy ones. All 13 people also had the standard treatment for multiple myeloma, which boosts white blood cell count.
Three months after the injection, 10 of the 13 were in remission or very close to it – a 77 per cent response rate – and the others showed drastic reduction in their cancer. Standard treatment alone gives a response rate of between 33 and 69 per cent. The original paper is available here . The work is encouraging, but a trial that does not include the standard therapy is needed, says Holger Auner, a myeloma specialist at Imperial College London."

Google and Apple spent more on Patents than R&D last year

parallel_prankster parallel_prankster writes  |  about 2 years ago

parallel_prankster (1455313) writes "NYTimes has an interesting article about how patents are really stiffling inovation in the tech industry. Today, almost every major technology company is involved in ongoing patent battles. Of course, the most significant player is Apple, industry executives say, because of its influence and the size of its claims: in August in California, the company won a $1 billion patent infringement judgment against Samsung. Former Apple employees say senior executives made a deliberate decision over the last decade, after Apple was a victim of patent attacks, to use patents as leverage against competitors to the iPhone, the company’s biggest source of profits. At a technology conference this year, Apple’s chief executive, Timothy D. Cook, said patent battles had not slowed innovation at the company, but acknowledged that some aspects of the battles had “kind of gotten crazy.” It is a complaint heard throughout the industry. The increasing push to assert ownership of broad technologies has led to a destructive arms race, engineers say. Some point to so-called patent trolls, companies that exist solely to sue over patent violations. Others say big technology companies have also exploited the system’s weaknesses. “There are hundreds of ways to write the same computer program,” said James Bessen, a legal expert at Harvard. And so patent applications often try to encompass every potential aspect of a new technology. When such applications are approved, Mr. Bessen said, “the borders are fuzzy, so it’s really easy to accuse others of trespassing on your ideas.” The number of patent applications, computer-related and otherwise, filed each year at the United States patent office has increased by more than 50 percent over the last decade to more than 540,000 in 2011. Google has received 2,700 patents since 2000, according to the patent analysis firm M-CAM. Microsoft has received 21,000."

Samsung's legal fillings show pre-IPhone designs

Samsung has shown that it was considering putting to market in the summer of 2006, six months before the unveiling of the iPhone, a number of phone designs that have been claimed by Apple as stolen from the Iphone. It extends to more than just the hardware — Samsung was also working on interfaces that looks remarkably like iOS (actually, that look remarkably like PalmOS) — in the summer and fall of 2006. Again, before the iPhone was released. Samsung is being accused of stealing, even thought the company was clearly working on what it supposedly stole before the iPhone was even released. Samsung's phones bear more resemblance to its own pre-iPhone designs than to the iPhone, yet Apple and its supporters still insist Samsung is a thief. Another article on this is available here ."

Google Tries Something Retro: Made in the U.S.A.

parallel_prankster parallel_prankster writes  |  more than 2 years ago

parallel_prankster (1455313) writes "NYTimes reports that etched into the base of Google’s new wireless home media player that was introduced on Wednesday is its most intriguing feature. On the underside of the Nexus Q is a simple inscription: “Designed and Manufactured in the U.S.A.” The Google executives and engineers who decided to build the player here are engaged in an experiment in American manufacturing. “We’ve been absent for so long, we decided, ‘Why don’t we try it and see what happens?’ ” said Andy Rubin, the Google executive who leads the company’s Android mobile business. The project will be closely watched by other electronics companies. It has become accepted wisdom that consumer electronics products can no longer be made in the United States. During the last decade, abundant low-cost Chinese labor and looser environmental regulations have virtually erased what was once a vibrant American industry. Since the 1990s, one American company after another, including Hewlett-Packard, Dell and Apple, has become a design and marketing shell, with production shifted to contract manufacturers in Shenzhen and elsewhere in China.

Now that trend may be showing early signs of reversing. It’s a trickle, but some American companies are again making products in the United States. While many of those companies have been small, like ET Water Systems, there have also been some highly visible moves by America’s largest consumer and industrial manufacturers. General Electric and Caterpillar, for example, have moved assembly operations back to the United States in the last year. (Airbus, a European company, is said to be near a deal to build jets in Alabama.)"

Supreme Court Upholds Key Part of Arizona Law

parallel_prankster parallel_prankster writes  |  more than 2 years ago

parallel_prankster (1455313) writes "NYTimes reports that the Supreme Court on Monday rejected much of Arizona’s tough new immigration law but allowed one key provision to stand, saying federal law did not pre-empt the state's instruction to its police to check the immigration status of people they detain. Several other important provisions of the law conflicted with federal laws, the court found, rejecting provisions that made it a state crime for immigrants not to register with the federal government or to seek or hold jobs without proper documents, and allowing warrantless arrests of some people suspected of being deportable. But on the question of allowing the status checks, the court was unanimous. “The court correctly held that federal immigration law trumps most of Arizona’s controversial immigration law," Stephen W. Yale-Loehr, who teaches immigration law at Cornell University and is co-author of a treatise on the subject, said. "But by upholding Arizona’s ‘check your papers’ provision, at least for now, the court has given other states a green light to try to enact similar immigration laws."
Even after the Supreme Court’s ruling that one key provision was not automatically pre-empted, immigration groups will be able to challenge it based on an argument that the court was not considering: that the law discriminates on the basis of race and ethnic background."

The case drew wide attention because his roommate, Tyler Clementi, jumped to his death from the George Washington Bridge in September 2010, a few days after learning of the spying. A jury convicted Mr. Ravi in March of all 15 counts against him, which included invasion of privacy and bias intimidation. The relatively light sentence — he faced up to 10 years in prison — surprised many who were watching the hearing, as it came after the judge spent several minutes criticizing Mr. Ravi’s behavior."

NIH Study Finds That Coffee Drinkers Have Lower Risk of Death

parallel_prankster parallel_prankster writes  |  more than 2 years ago

parallel_prankster (1455313) writes "Older adults who drank coffee — caffeinated or decaffeinated — had a lower risk of death overall than others who did not drink coffee, according to a study by researchers from the National Cancer Institute (NCI), part of the National Institutes of Health, and AARP. Coffee drinkers were less likely to die from heart disease, respiratory disease, stroke, injuries and accidents, diabetes, and infections, although the association was not seen for cancer. These results from a large study of older adults were observed after adjustment for the effects of other risk factors on mortality, such as smoking and alcohol consumption. They also found that the association between coffee and reduction in risk of death increased with the amount of coffee consumed. Relative to men and women who did not drink coffee, those who consumed three or more cups of coffee per day had approximately a 10 percent lower risk of death. Researchers caution, however, that they can't be sure whether these associations mean that drinking coffee actually makes people live longer.

Facebook Co-Founder Saverin Gives Up U.S. Citizenship Before IPO

parallel_prankster (1455313) writes "Bloomberg reports that Eduardo Saverin, the billionaire co- founder of Facebook Inc. (FB), renounced his U.S. citizenship before an initial public offering that values the social network at as much as $96 billion, a move that may reduce his tax bill.
Facebook plans to raise as much as $11.8 billion through the IPO, the biggest in history for an Internet company. Saverin’s stake is about 4 percent, according to the website Who Owns Facebook. At the high end of the IPO valuation, that would be worth about $3.84 billion. Saverin, 30, joins a growing number of people giving up U.S. citizenship, a move that can trim their tax liabilities in that country.
Saverin won’t escape all U.S. taxes. Americans who give up their citizenship owe what is effectively an exit tax on the capital gains from their stock holdings, even if they don’t sell the shares, said Reuven S. Avi-Yonah, director of the international tax program at the University of Michigan’s law school. For tax purposes, the IRS treats the stock as if it has been sold."

Silicon Nanospheres Could Be Building Blocks Of Optical Invisibility Cloaks

parallel_prankster parallel_prankster writes  |  more than 2 years ago

parallel_prankster (1455313) writes "In recent years researchers have made great strides in their theoretical understanding of how "Invisibility Cloaks" work and consequently built increasingly complex and impressive devices. But these devices generally work in the microwave region of the electromagnetic spectrum, where wavelengths are measured in centimetres. Enter Arseniy Kuznetsov at the Data Storage Institute in Singapore and a few pals. These guys say they've found an alternative to split ring resonators that work well at optical frequencies, with few losses. This alternative is silicon nanospheres between 100 and 200 nm in diameter. It turns out that these spheres behave just like split ring resonators in the sense that they allow for the same kind of magnetic resonances when they interact with light. This magnetic resonance can also be tuned to match any part of the visible spectrum simply selecting spheres of a specific size. That's important because it opens up an entirely new way make invisibility cloaks that operate in the visible region. "These optical systems open up new perspectives for fabrication of low-loss optical metamaterials and nanophotonic devices," they say. The trouble of course is making these spheres."

Quantum Entanglement Can Reach into the Past

parallel_prankster parallel_prankster writes  |  more than 2 years ago

parallel_prankster (1455313) writes "Physicists have, for the first time, demonstrated in an experiment that the decision whether two particles were in an entangled or in a separable quantum state can be made even after these particles have been measured and may no longer exist. Entangled particles exhibit correlations which are stronger and more intricate than those allowed by the laws of classical physics. If two particles are in an entangled quantum state, they have perfectly defined joint properties at the expense of losing their individual properties. This is like having two dice which have no orientation until they are subject to measurement, upon which they certainly show the same (random) side up. In contrast, so-called separable quantum states allow for a classical description, because every particle has well-defined properties on its own. Two dice, each one of them with its own well-defined orientation, are in a separable state. Now, one would think that at least the nature of the quantum state must be an objective fact of reality. Either the dice are entangled or not. Zeilinger's team has now demonstrated in an experiment that this is not always the case.

World's Fastest Random Number Generator based on Sub-Atomic Noise in Vaccum

parallel_prankster parallel_prankster writes  |  more than 2 years ago

parallel_prankster (1455313) writes "Researchers Professor Ping Koy Lam, Dr Thomas Symul and Dr Syed Assad from the ANU ARC Centre of Excellence for Quantum Computation and Communication Technology have developed the fastest random number generator in the world by listening to the 'sounds of silence'. Vacuum was once thought to be completely empty, dark, and silent until the discovery of the modern quantum theory. Since then scientists have discovered that vacuum is an extent of space that has virtual sub-atomic particles spontaneously appearing and disappearing. It is the presence of these virtual particles that give rise to random noise.
The researchers have tuned their very sensitive light detectors to listen to vacuum — a region of space that is empty. Professor Lam said " This 'vacuum noise' is omnipresent and may affect and ultimately pose a limit to the performances of fibre optic communication, radio broadcasts and computer operation." The random number generator is online and can be accessed from anywhere, anytime around the world here "

Harvard Scientists Develop Nanorobots to Kill Cancer Cells

parallel_prankster parallel_prankster writes  |  more than 2 years ago

parallel_prankster (1455313) writes "Scientists at Harvard University’s Wyss Institute for Biologically Inspired Engineering said they have developed a robotic device made from DNA that could potentially seek specific cell targets and deliver important molecular instructions, such as telling cancer cells to self-destruct. The technology may some day be used to program immune responses to treat various diseases, they wrote in today’s issue of Science. Using the DNA origami method, in which complex three-dimensional shapes and objects are constructed by folding strands of DNA, the researchers created a nanosized robot that looks like an open barrel with its halves connected by a hinge. The DNA barrel, which acts as a container, is held shut by special DNA latches that can recognize and seek out combinations of cell-surface proteins, including disease markers. When the latches find their targets, they reconfigure, causing the two halves of the barrel to swing open and expose the contents or “payload.” The container can hold various types of payloads, including certain molecules with encoded instructions that can interact with specific cell surface signaling receptors. “We can finally integrate sensing and logical computing functions via complex, yet predictable, nanostructures—some of the first hybrids of structural DNA, antibodies, aptamers and metal atomic clusters—aimed at useful, very specific targeting of human cancers and T-cells,” George Church, a Wyss faculty member and principal investigator on the project, said in a statement."

parallel_prankster (1455313) writes "Researchers in MIT are developing tiny robots that can assemble themselves into products and then disassemble when no longer needed. "A heap of smart sand would be analogous to the rough block of stone that a sculptor begins with. The individual grains would pass messages back and forth and selectively attach to each other to form a three-dimensional object; the grains not necessary to build that object would simply fall away. When the object had served its purpose, it would be returned to the heap. Its constituent grains would detach from each other, becoming free to participate in the formation of a new shape." To attach to each other, to communicate and to share power, the cubes use 'electropermanent magnets,' materials whose magnetism can be switched on and off with jolts of electricity.

parallel_prankster (1455313) writes "Anonymous Industry sources have confirmed that Google is developing a low-budget tablet in an attempt to bolster a floundering stable of Android-based tablets. The rumored 7-inch tablet, dubbed the Nexus Tablet, could cost the same price as the Amazon Kindle Fire, $199, or even better — $149.
Industry sources say that Asus is working with Google to make a 7-inch tablet loosely based off of the Asus Memo 370T, which debuted at CES 2012. Industry sources say that Asus is working with Google to make a 7-inch tablet loosely based off of the Asus Memo 370T, which debuted at CES 2012. An anonymous source from a U.S. supply chain has told the tech blog Android and Me that the new small-form tablet will cost $149, while the more visited site the Verge has a source that says the new tablet will cost $199."

Startup uses 3-D Printer to build human muscle tissue

parallel_prankster (1455313) writes "A San Diego-based startup Organovo is building human muscle tissue with the help of 3-D printers . Organovo’s product is so similar to human tissue, it could help researchers identify drugs that will fail long before they reach clinical trials. This technology lets cells interact with each other – like the way they do in the body. They’re packed together tightly and incubated, prompting them to trade chemical signals. When they’re printed, the cells are kept bunched together in a paste that helps them grow, migrate, and align themselves properly. So far, Organovo has built tissue of several types, including cardiac muscle, lung, and blood vessels. They’ve only made small pieces of tissue, but the goal is to use their 3-D printer to make organs for transplants."
