Children with a certain genetic marker are more likely to play violent video games and watch violent TV shows and movies, according to a new study.
Researchers in the Netherlands analyzed surveys from 1,612 parents of Dutch children ages 5-9. The parents noted how much violent TV programming their children viewed, as well as how often they played violent video games.
Then they looked at DNA samples taken from the same children at birth.
Children that had a specific variant of the serotonin-transporter gene on average consumed more violent media and displayed more ADHD-related behaviors.
“Our results indicate that children’s violent media use is partly influenced by genetic factors. This could mean that children with this gene variant are more likely to seek out stimulating activities, such as violent television viewing and video game playing,” said Sanne Nikkelen with the University of Amsterdam’s School of Communication Research.
The researchers stress that this is the first of its kind study to link genetic factors with consumption of violent media and caution that environmental factors may also be at work.
The study is published in the Journal of Communication.
What happened before the Big Bang? Was there even a Big Bang? These are the questions that plague theoretical physicists in their quest to understand the universe.
Now a scientist is adding a new wrinkle to the fabric of space…our entire universe could exist in the black hole of another universe, reports National Geographic.
Modern theories about the Big Bang suggest that about 15 billion years ago, everything in our universe, all the mass and energy, existed in a single, finite point.
Einstein’s theory of relativity tells us a black hole is a giant star that collapses into a single point, with gravity so strong not even light can escape.
Nikodem Poplawski with the University of New Haven speculates that the seed for our universe could have been planted in a black hole.
But this theory would depend on the existence of other universes that exist parallel to our own.
Dr. Poplawski suggests that everything sucked into a black hole is scrunched down to an impossibly small point and then explodes outward, creating alternate universes.
And one of those universes just might be our own.
