Why some genes are silenced: Researchers find clue as to how notes are played on the 'g... - 0 views

  •  
    ScienceDaily (May 13, 2011) - Japanese and U.S. scientists in the young field of epigenetics have reported a rationale as to how specific genes are silenced and others are not. Because this effect can be reversed, it may be possible to devise therapies for cancer and other diseases using this information.

    "What, if anything, is the world trying to tell us? On some level it seems that things are getting harder - it is tougher to be a dominant player in sports given global talent pools, better training, more mimicry, etc. Similarly, science in many important areas does seem stalled, with progress proceeding glacially, whether it is drug discovery, or fundamental physics, or energy."

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."

Among Students, Web Connection More Important than Car - The Daily Stat - September 26,... - 0 views

  •  
    64% of college students in a global survey said that if forced to choose, they would opt for having an internet connection rather than a car. 40% said the internet is more important to them than dating, going out with friends, or listening to music. The Cisco Connected World Technology Report draws on surveys of some 1,400 students in 14 countries.Source: Is the Internet a Fundamental Human Necessity?

Description and Specification of Graphene - 0 views

  •  
    Graphene is a single-atom-thick sheet made from combined carbon atoms. The carbon atoms are bonded together to share electron in a hexagonal, honeycomb-like structure. It is a single atom thick layered 2D material ever discovered in the world. It is made up of a hexagonal lattice pattern of carbon atoms in a monolithic honeycomb-like structure. It is a layer of SP2 single bonded carbon atoms arranged like a chicken wire mesh. It is 200 times stronger than stainless steel (SS) and 100 thousand times thinner than the human hair. It is the slimmest and strongest compound available on the earth. Anybody would be amazed when they know that we have found a material which is harder than diamond, yet lightweight, stronger than steel, but also highly flexible, and this material can be mined from the earth as it occurs naturally. It is yet thin enough to be mistaken for a saran wrap. Apart from the optimum physical properties, the other features are also impressive. Properties of Graphene These are some prominent features which make it a hi-tech material: Excellent Electronic Conductor Chief electronic property makes it an efficient Zero-Overlap Semi metal and gives it sufficient electrical conductivity. Carbon atoms possess typically 2 electrons in the inner shell, and 4 electrons in the outer orbit, total 6 electrons. Although conventionally, the outer 4 electrons in carbon can connect with another atom, each, the atoms can form a 2-dimensional bond with three atoms per single atom. This leaves an electron available for electronic conduction. Such electrons are known as 'Pi' electrons and found above and below in sheet. Ultimate Tensile Strength Mechanical strength is another prominent property of the material. It considered as being the foremost most robust material ever discovered, owing to the 0.142 Nm-long carbon bonds. It also possesses ultimate tensile strength, measuring 130 Gigapascals (or 130,000,000,000 Pascals). Compared to the tensile strength of industr

SkyandTelescope.com - Homepage News - "Pioneer Anomaly" Solved? - 0 views

  • Turyshev has spent the last several years retrieving archival tracking records from obsolete storage media (those classic magnetic tapes, some of them corrupted) as well as detailed specifications of the Pioneer spacecraft itself from 40 years ago. He likens his searching and discovery to rooting around a dusty attic. "No one told me what I'd be getting into," he says. The Pioneer missions lasted so long that they outlived programming languages and data formats. (The Pioneers were launched in the days of punched cards.)

The Technium: Chosen, Inevitable, and Contingent - 0 views

  • There are two senses of "inevitable" when used with technology. In the first case, an invention merely has to exist once. In that sense, every technology is inevitable because sooner or later some mad tinkerer will cobble together almost anything that can be cobbled together. Jetpacks, underwater homes, glow-in-the-dark cats, forgetting pills — in the goodness of time every invention will inevitably be conjured up as a prototype or demo. And since simultaneous invention is the rule not the exception, any invention that can be invented will be invented more than once. But few will be widely adopted. Most won't work very well. Or more commonly they will work but be unwanted. So in this trivial sense, all technology is inevitable. Rewind the tape of time and it will be re-invented. The second more substantial sense of "inevitable" demands a level of common acceptance and viability. A technology's use must come to dominate the technium or at least its corner of the technosphere. But more than ubiquity, the inevitable must contain a large-scale momentum, and proceed on its own determination beyond the free choices of several billion humans. It can't be diverted by mere social whims.

Sociology and History: Shapin on the Merton Thesis « Ether Wave Propaganda - 1 views

  • Shapin observed that the link Merton drew between Puritanism and seventeenth-century English science was a matter of happenstance rather than determinism. According to Merton, science requires certain “values” and “sentiments” allowing intellectual individualism, and fostering not only an interest in the transcendent, but also secular improvement. It so happened that these values and sentiments were to be found in Puritan asceticism and sense of social obligation, which thus provided a social context in which science could develop. Definitively, this was not to say that Puritanism provided a unique source of these values and sentiments, or that science did not have other roots. It was obviously possible for science to develop in Catholic contexts as well, despite the less hospitable value system of Catholicism. The confluence of values simply seemed to promise some insight into the growth of science in a particular time and place.
  • Robert K. Merton’s “functionalist” sociology viewed “science” as a kind of Weberian ideal type — a form of thought that is identifiable by its peculiar, philosophically-defined characteristics. Merton’s sociology of science held that this thought could also be identified with social behaviors, characterized by a set of “norms”, which made the thought possible. The Merton Thesis (which slightly predates Merton’s enumeration of science’s norms) holds that the rise of science in early-modern England could be linked to the social behaviors valued by the Puritanism of that milieu. This was the subject of Merton’s PhD thesis and his 1938 book Science, Technology and Society in Seventeenth-Century England.
