    I thought of the Aurora Borealis as a slow motion version of what we cannot see with the naked eye. Particles coming together in an astounding manner and in a sequential order as we understand it. Is this Emergence?

Free will is an illusion, biologist says - 2 views

  •  
    "When biologist Anthony Cashmore claims that the concept of free will is an illusion, he's not breaking any new ground. At least as far back as the ancient Greeks, people have wondered how humans seem to have the ability to make their own personal decisions in a manner lacking any causal component other than their desire to "will" something. But Cashmore, Professor of Biology at the University of Pennsylvania, says that many biologists today still cling to the idea of free will, and reject the idea that we are simply conscious machines, completely controlled by a combination of our chemistry and external environmental forces."

Dogs Decoded | Watch Free Documentary Online - 6 views

  •  
    Dogs Decoded reveals the science behind the remarkable bond between humans and their dogs and investigates new discoveries in genetics that are illuminating the origin of dogs - with surprising implications for the evolution of human culture.
    Other research is proving what dog lovers have suspected all along: Dogs have an uncanny ability to read and respond to human emotions.
    Humans, in turn, respond to dogs with the same hormone responsible for bonding mothers to their babies.
    How did this incredible relationship between humans and dogs come to be? And how can dogs, so closely related to fearsome wild wolves, behave so differently?

Astronomers discover complex organic matter in the universe | KurzweilAI - 1 views

  •  
    Organic compounds of unexpected complexity exist throughout the universe, Prof. Sun Kwok and Dr. Yong Zhang of the University of Hong Kong have discovered, suggesting that complex organic compounds can be synthesized in space even when no life forms are present.
    The organic substance they found contains a mixture of aromatic (ring-like) and aliphatic (chain-like) components that are so complex, their chemical structures resemble those of coal and petroleum. Since coal and oil are remnants of ancient life, this type of organic matter was thought to arise only from living organisms.
    Unidentified radiation from the universe
    The researchers investigated an unsolved phenomenon: a set of infrared emissions detected in stars, interstellar space, and galaxies, known as "Unidentified Infrared Emission features." From observations taken by the Infrared Space Observatory and the Spitzer Space Telescope, Kwok and Zhang showed that the astronomical spectra have chemical structures that are much more complex that previously thought. By analyzing spectra of star dust formed in exploding stars called novae, they show that stars are making these complex organic compounds on extremely short time scales of weeks, and ejecting it into the general interstellar space, the region between stars.
    "Our work has shown that stars have no problem making complex organic compounds under near-vacuum conditions," says Kwok. "Theoretically, this is impossible, but observationally we can see it happening."
    Most interestingly, this organic star dust is similar in structure to complex organic compounds found in meteorites. Since meteorites are remnants of the early Solar System, the findings raise the possibility that stars enriched the early Solar System with organic compounds. The early Earth was subjected to severe bombardments by comets and asteroids, which potentially could have carried organic star dust. Whether these delivered organic compounds played any role in the development of l

    "However, distilled water has no such minerals, and if you put it in a relatively smooth container and stick it in the microwave, the water can be heated beyond the normal boiling point and will remain perfectly still.

    Then, you toss in an object in and watch it explode"

Brain scans support findings that IQ can rise or fall significantly during adolescence - 1 views

  •  
    ScienceDaily (Oct. 20, 2011) - IQ, the standard measure of intelligence, can increase or fall significantly during our teenage years, according to research funded by the Wellcome Trust, and these changes are associated with changes to the structure of our brains. The findings may have implications for testing and streaming of children during their school years.

Parenting Style Plays Key Role In Teen Drinking : NPR - 0 views

  •  
    For teenagers, friends play a big role in the decision to take that first drink. And by the 12th grade, more than 65 percent of teens have at least experimented with alcohol. But what parents do during the high school years can also influence whether teens go on to binge drink or abuse alcohol. Researchers at Brigham Young University have found that teenagers who grow up with parents who are either too strict or too indulgent tend to binge drink more than their peers.

  •  
    For some adults, there is a tendency to go beyond the call of duty. Particularly, when they are faced with choosing to allow or not allow. Maybe the scientific explanation is to do or not to do. And the reaction isn't always the most appropriate but it is better to be safe than sorry. What is the scientific explanation for adults that don't react or react inappropriately even when it's involves saving a teenager? What is the scientific solution for those in the center of difficult situations, who are not strict or liberal? What does a mind do when it is present many times in a teenage situation and it is not the parent?
