Who makes up the edublogosphere? - Part 1

Are edubloggers mostly white and middle class? What proportion of edubloggers have advanced degrees in instructional technology?


Brian Grenier wants to find out the answers to these and other questions. If you're an education blogger, please

  1. complete his quick survey (if you're really bold, put your blog URL in the comments area!), and
  • spread the word via your own blog so that others will complete the survey too.
  • Let's help Brian get a decent set of data. These questions would have been great to include on my Education Blogosphere Survey in January!

    Plants have awareness and intelligence, argue scientists

    Research in plant neurobiology shows that plants have senses, intelligence and emotions.

    Surprising Science
    • The field of plant neurobiology studies the complex behavior of plants.
    • Plants were found to have 15-20 senses, including many like humans.
    • Some argue that plants may have awareness and intelligence, while detractors persist.

    Vaping changes blood vessels after one use, even without nicotine

    E-cigarettes may be safer than traditional cigarettes, but they come with their own risks.

    • A new study used an MRI machine to examine how vaping e-cigarettes affects users' cardiovascular systems immediately after inhalation.
    • The results showed that vaping causes impaired circulation, stiffer arteries and less oxygen in their blood.
    • The new study adds to a growing body of research showing that e-cigarettes – while likely safer than traditional cigarettes – are far from harmless.

    Space is dead: A challenge to the standard model of quantum mechanics

    Since the idea of locality is dead, space itself may not be an aloof vacuum: Something welds things together, even at great distances.

    • Realists believe that there is an exactly understandable way the world is — one that describes processes independent of our intervention. Anti-realists, however, believe realism is too ambitious — too hard. They believe we pragmatically describe our interactions with nature — not truths that are independent of us.
    • In nature, properties of Particle B may be depend on what we choose to measure or manipulate with Particle A, even at great distances.
    • In quantum mechanics, there is no explanation for this. "It just comes out that way," says Smolin. Realists struggle with this because it would imply certain things can travel faster than light, which still seems improbable.
