Amy Goodman: WikiLeaks and the End of U.S. 'Diplomacy' - Truthdig - 0 views

  •  
    WikiLeaks is again publishing a trove of documents, in this case classified U.S. State Department diplomatic cables. The whistle-blower website will gradually be releasing more than 250,000 of these documents in the coming months so that they can be analyzed and gain the attention they deserve. The cables are internal, written communications among U.S. embassies around the world and also to the U.S. State Department. WikiLeaks described the leak as "the largest set of confidential documents ever to be released into the public domain [giving] an unprecedented insight into U.S. government foreign activities."

DNA can discern between two quantum states, research shows - 0 views

  •  
    ScienceDaily (June 4, 2011) - Do the principles of quantum mechanics apply to biological systems? Until now, says Prof. Ron Naaman of the Institute's Chemical Physics Department (Faculty of Chemistry), both biologists and physicists have considered quantum systems and biological molecules to be like apples and oranges. But research he conducted together with scientists in Germany, which appeared recently in Science, shows that a biological molecule -- DNA -- can discern between quantum states known as spin.

Natural brain state is primed to learn - life - 19 August 2011 - New Scientist - 0 views

  •  
    Apply the electrodes... Externally modulating the brain's activity can boost its performance. The easiest way to manipulate the brain is through transcranial direct current stimulation (tDCS), which involves applying electrodes directly to the head to influence neuron activity with an electric current. Roi Cohen Kadosh's team at the University of Oxford showed last year that targeting tDCS at the brain's right parietal lobe can boost a person's arithmetic ability - the effects were still apparent six months after the tDCS session (newscientist.com/article/dn19679). More recently, Richard Chi and Allan Snyder at the University of Sydney, Australia, demonstrated that tDCS can improve a person's insight. The pair applied tDCS to volunteers' anterior frontal lobes - regions known to play a role in how we perceive the world - and found the participants were three times as likely as normal to complete a problem-solving task (newscientist.com/article/dn20080). Brain stimulation can also boost a person's learning abilities, according to Agnes Flöel's team at the University of Münster in Germany. Twenty minutes of tDCS to a part of the brain called the left perisylvian area was enough to speed up and improve language learning in a group of 19 volunteers (Journal of Cognitive Neuroscience, DOI: 10.1162/jocn.2008.20098). Using the same technique to stimulate the brain's motor cortex, meanwhile, can enhance a person's ability to learn a movement-based skill (Proceedings of the National Academy of Sciences, DOI: 10.1073/pnas.0805413106).

Amateur Science and the Rise of Big Science | Citizen Scientists League - 0 views

  • Several trends came together to increase the professional nature of scientific work. First was the increasing cost of scientific work and its complexity. Scientific equipment became more precise and expensive. Telescopes, like those by Herschel, became bigger and bigger. Also, the amount of knowledge one needed to gain to contribute became increasingly daunting.
  • Second, the universities changed. Pioneered by the German states, which at the beginning of the 19th century was dismissed as a scientific backwater, universities began offering focused majors which trained students in a specific discipline rather than classical education as a whole. This was pioneered by Wilhelm von Humboldt, brother of the famous scientist Alexander von Humboldt, who was the Prussian Minister of Education.
  • Germany, once united, also provided impetus to two other trends that accelerated their dominance of science and the decline of amateurs. First, was the beginning of large-scale state sponsorship of science through grants which were first facilitated through the Kaiser Wilhelm Institute (now the Max Planck Institute). This eventually supplanted prizes as the dominant large-scale source of scientific funding. Countries like France that relied on prizes began to fall behind. Second, was the intimate cooperation between industrial firms like BASF and universities.

  • he final nail in the coffin was undoubtedly the Second World War. The massive mobilization of scientific resources needed to win and the discovery of war-winning inventions such as the atomic bomb and self-correcting bomb sight (with help from Norbert Wiener of MIT) convinced the nations of the world that the future was in large-scale funding and support of science as a continuous effort. Vannevar Bush, former president of MIT, and others pioneered the National Science Foundation and the military also invested heavily in its own research centers. Industrial labs such as those from Bell Labs, GE, Kodak, and others began dominating research as well. Interestingly, the first military investment in semiconductors coupled with research from Bell Labs led to what is now known as Silicon Valley.

Tiny LEDs Pump out Quantum-Entangled Photons | 80beats | Discover Magazine - 0 views

  •  
    LEDsThe strange quantum state of entanglement isn't just challenging to think about, it's hard to create. This "spooky" phenomenon-in which two particles are linked, even if they're separated by distance-can be created by scientists in the lab using bulky lasers. But scientists published a study in Nature today in which they created a light-emitting diode (LED) that produces entangled photons.

EPFL spinoff turns thousands of 2D photos into 3D images | KurzweilAI - 0 views

  •  
    Researchers in EPFL's Computer Vision Laboratory developed a computer-based modeling service that generates a 3D image from up to thousands of 2D shots, with all the processing done in the cloud. Since April, the EPFL startup Pix4D has been offering the modeling service with a fourth dimension: time. Now, individuals and small businesses looking for fast, cheap, large-scale 3D models can get them without investing in heavy processing, the company states. With Pix4D, users upload a series of photos of an object, and within 30 minutes they have a 3D image. The software defines "points of interest" from among the photos, or common points of high-contrast pixels. Next, the program pastes the images together seamlessly by matching up the points of interest. Much in the same way our two eyes work together to calculate depth, the software computes the distance and angle between two or more photos and lays the image over the model appropriately, creating a highly accurate 3D model that avoids the time intensive, "point by point" wireframe method. With Pix4D's 3D models, you can navigate in all directions as well as change the date on a timeline to see what a place looked like at different times of the year. The company is collaborating with several drone makers (including another EPFL startup,senseFly) to market their software as a package with senseFly's micro aerial vehicles, or autonomous drones. Pix4D's time element avoids waiting for Google to update its satellite data or for an expensive plane to fly by and take high-resolution photos. Farmers, for example, can now send relatively inexpensive flying drones into the air to take pictures as often as they like, allowing them to survey the evolution of their crops over large distances and long periods of time. And since the calculations are done on a cloud server, the client doesn't need a powerful computer of his or her own.

Mind-reading scan identifies simple thoughts - health - 26 May 2011 - New Scientist - 0 views

  •  
    A new new brain imaging system that can identify a subject's simple thoughts may lead to clearer diagnoses for Alzheimer's disease or schizophrenia - as well as possibly paving the way for reading people's minds. Michael Greicius at Stanford University in California and colleagues used functional magnetic resonance imaging (fMRI) to identify patterns of brain activity associated with different mental states. He asked 14 volunteers to do one of four tasks: sing songs silently to themselves; recall the events of the day; count backwards in threes; or simply relax. Participants were given a 10-minute period during which they had to do this. For the rest of that time they were free to think about whatever they liked. The participants' brains were scanned for the entire 10 minutes, and the patterns of connectivity associated with each task were teased out by computer algorithms that compared scans from several volunteers doing the same task. This differs from previous experiments, in which the subjects were required to perform mental activities at specific times and the scans were then compared with brain activity when they were at rest. Greicius reasons his method encourages "natural" brain activity more like that which occurs in normal thought.

Social networking's good and bad impacts on kids | KurzweilAI - 0 views

  •  
    Social media present risks and benefits to children but parents who try to secretly monitor their kids' activities online are wasting their time, says Larry D. Rosen, Ph.D., professor of psychology at California State University, Dominguez Hills. Rosen identifies potential adverse effects of social media, including: Teens who use Facebook more often show more narcissistic tendencies, while young adults who have a strong Facebook presence show more signs of other psychological disorders, including antisocial behaviors, mania, and aggressive tendencies. Daily overuse of media and technology has a negative effect on the health of all children, especially preteens and teenagers, by making them more prone to anxiety, depression, and other psychological disorders, and making them more susceptible to future health problems. Facebook can be distracting and can negatively impact learning. Studies found that middle school, high school and college students who checked Facebook at least once during a 15-minute study period achieved lower grades. Rosen says new research has also found positive influences linked to social networking, including: Young adults who spend more time on Facebook are better at showing "virtual empathy" to their online friends. Online social networking can help introverted adolescents learn how to socialize. Social networking can provide tools for teaching in compelling ways that engage young students. "If you feel that you have to use some sort of computer program to surreptitiously monitor your child's social networking, you are wasting your time. Your child will find a workaround in a matter of minutes," he says. "You have to start talking about appropriate technology use early and often and build trust, so that when there is a problem, whether it is being bullied or seeing a disturbing image, your child will talk to you about it."

25% of US car accidents due to using gadgets | KurzweilAI - 0 views

  •  
    Driving distractions such as cell phones and other electronic devices cause as much as 25% of all U.S. car accidents, researchers at the Governors Highway Safety Association have found, WinBETA notes. A major finding was that being distracted was the cause of 15 to 25% of all accidents, ranging from minor property damage to death. Their findings suggest that distracted driving accidents be reported in accident reports to assist in evaluating distracted driving laws and programs. They propose creating low-cost roadway measures that alert motorists when they are drifting out of their driving lane. They also propose that all cell phones be banned on the road, even hands-free versions. In another report by The New York Times, police in Syracuse and Hartford have handed out nearly 20,000 tickets for illegal use of a phone while driving - either for texting or use of a handheld phone. According to the federal government, these efforts have had the desired effect: distracted driving has fallen sharply. Their research shows that drivers talking on a phone are four times as likely to get into a crash as those not on a phone, and that the risks for motorists who text are at least twice as high. In Syracuse, handheld cellphone use and texting have each fallen by one-third. In Hartford, handheld cellphone use by drivers fell 57 percent while texting fell by 75 percent, the Times reports.
