Science and Health

1.      Vast majority of teens are sleep-deprived

-          Insufficient sleep impairs learning, impulse control, and judgment. It appears to even predispose people to disease. Indeed, one motivation for the survey was to probe kids’ behaviors and the extent to which these might help explain four leading causes of death among 10- to 24-year olds: motor-vehicle crashes, other unintentional injuries, homicide and suicide

3.      Bermuda Triangle hypothesis?

-          Earlier this year the discovery of mysterious craters in Siberia, began a debate of how the "Bermuda Triangle" claims its unfortunate victims. Experts are now discussing the idea that large explosions of trapped methane could be responsible for taking down ships in the North Atlantic Ocean with little or no warning.

-          Pulling an all-nighter does a number on the brain, a new study finds. People who lost a night of sleep also lost much of their willpower to eat right. This connection could help explain why people who don’t regularly get a good night’s sleep are more likely to be obese.

13.  Full moon shortchanges sleep

-          Werewolves aren’t the only creatures thrown off by the moon’s cycles. A full moon subtly disrupts people’s sleep, reports a Swiss team of scientists. Even people dozing in a lab without windows experienced a small shortfall in zzz’s.

14.  A mind for math

-          The anatomy of your brain may be linked with how easily you learn math, a new study finds. Deep inside each side of the brain lies a region called the hippocampus (plural hippocampi). It’s shaped like a seahorse (hippo campus means “sea monster” in Greek) and helps make memories. The size of this brain region and how it’s wired to others may play important roles in how children learn math, reports a study published in April.

15.  Fooling the mind’s eye

-          Neuroscientists and psychologists study how the mind works and how emotions can affect our responses. These scientists have begun teaming up with magicians to study how tricks can manipulate critical attention and awareness.
