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."

Scientists Disarm AIDS Virus' Attack on Immune System | Health | English - 0 views

  •  
    Scientists say they have found a way to disarm the AIDS virus in research that could lead to a vaccine.  Researchers have discovered that if they eliminate a cholesterol membrane surrounding the virus, HIV cannot disrupt communication among disease-fighting cells and the immune system returns to normal.

An illustrated guide to the latest climate science « Climate Progress - 0 views

  •  
    "In 2009, the scientific literature caught up with what top climate scientists have been saying privately for a few years now: * Many of the predicted impacts of human-caused climate change are occurring much faster than anybody expected - particularly ice melt, everywhere you look on the planet. * If we stay anywhere near our current emissions path, we are facing incalculable catastrophes by century's end, including rapid sea level rise, massive wildfires, widespread Dust-Bowlification, large oceanic dead zones, and 9°F warming - much of which could be all but irreversible for centuries. And that's not the worst-case scenario! * The consequences for human health and well being would be extreme. That's no surprise to anybody who has talked to leading climate scientists in recent years, read my book Hell and High Water (or a number of other books), or followed this blog. Still, it is a scientific reality that I don't think more than 2 people in 100 fully grasp, so I'm going to review here the past year in climate science. I'll focus primarily on the peer-reviewed literature, but also look at some major summary reports."

Apomediation - P2P Foundation - 0 views

  •  
    Apomediation is a new scholarly socio-technological term that characterizes the process of disintermediation (intermediaries are middlemen or "gatekeeper", e.g. health professionals giving "relevant" information to a patient, and disintermediation means to bypass them), whereby the former intermediaries are functionally replaced by apomediaries, i.e. network/group/collaborative filtering processes [Eysenbach, 2008 [WebCite] and 2007b]. The difference between an intermediary and an apomediary is that an intermediary stands "in between" (latin: inter- means "in between") the consumer and information/service, i.e. is absolutely necessary to get a specific information/service. In contrast, apomediation means that there are agents (people, tools) which "stand by" (latin: apo- means separate, detached, away from) to guide a consumer to high quality information/services/experiences, without being a prerequisite to obtain that information/service in the first place. The switch from an intermediation model to an apomediation model has broadimplications for example for the way people judge credibility, as hypothesized and elaborated in more detail elsewhere [

Just How Dangerous Is Sitting All Day? [INFOGRAPHIC] - 0 views

  •  
    Sitting down, which most of us do for at least eight hours each day, might be the worst thing we do for our health all day. We've been preaching the benefits of stand-up desks for a while around here - and no one needs this good news more than social media-obsessed web geeks. A recent medical journal study showed that people who sit for most of their day are 54% more likely to die of a heart attack.

Cheap, 'safe' drug kills most cancers - health - 17 January 2007 - New Scientist - 0 views

  •  
    It sounds almost too good to be true: a cheap and simple drug that kills almost all cancers by switching off their "immortality". The drug, dichloroacetate (DCA), has already been used for years to treat rare metabolic disorders and so is known to be relatively safe.

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.

Hello, Darkness - 96.03 - 0 views

  • But the implication of electricity in the sleep deficit seems hard to argue with. Whatever it is that we wish or are made to do--pursue leisure, earn a living--there are simply far more usable hours now in which to do it
  • In the United States at midnight more than five million people are at work at full-time jobs. Supermarkets, gas stations, copy shops--many of these never close.
  • Living with electric lights makes it difficult to retrieve the experience of a non-electrified society. For all but the very wealthy, who could afford exorbitant arrays of expensive artificial lights, nightfall brought the works of daytime to a definitive end. Activities that need good light--where sharp tools are wielded or sharply defined boundaries maintained; purposeful activities designed to achieve specific goals; in short, that which we call work--all this subsided in the dim light of evening. Absent the press of work, people typically took themselves safely to home and were left with time in the evening for less urgent and more sensual matters: storytelling, sex, prayer, sleep, dreaming.

  • John Staudenmaier, a historian of technology and a Jesuit priest, for a recent conference at MIT. (The essay will appear in a book called The Idea of Progress Revisited, edited by Leo Marx and Bruce Mazlish.) Staudenmaier makes the point--obvious when brought up, though we've mostly lost sight of it--that from the time of the hominid Lucy, in Hadar, Ethiopia, to the time of Thomas Edison, in West Orange, New Jersey, the onset of darkness sharply curtailed most kinds of activity for most of our ancestors.

    Speculative connections between electric lighting, sleep deficits, and health.
  •  
    I wonder if the driving force behind the sleep deficit is in fact more pervasive, and indeed global in nature: the triumph of light.
