Kids and Adults Share Nightmares

How frequent are nightmares for toddlers, and what causes them? Those are questions researchers at the University of Montreal hoped to answer. They asked parents of about a thousand children to estimate the occurrence of their child’s nightmares from age two and a half through age six. The parents were also questioned about their child’s disposition.

First, it turns out nightmares aren’t so frequent. About a third of the parents reported no nightmares at all. And then there’s the second result. Kids who were called “difficult” as early as 5 months were more likely to suffer from nightmares as toddlers. And the ones who at a year and a half were more anxious, more likely to cry, and more difficult to calm down were also more likely to have bad dreams.

The study authors say this means children may be, well, like little adults.  It’s already well established that adults tend to express real-live stress and emotional problems as nightmares. The researchers suggest that focusing on the kids’ day-time issues, and on parenting techniques, may help banish night-time demons.

Invading Ants Go On Diet

If you’re an invading, meat-eating Argentinian ant, and you run out of prey, there’s only one thing to do if you want to keep invading—become a vegetarian. And that’s just what the carnivorous Argentinian ants that have invaded California did.  They switched and began to eat vegetable matter.  No, these two-millimeter long critters didn’t develop moral qualms about eating meat and they aren’t trying to save the planet.  They just ran out of their first choice, native ants.  Researchers writing in the Proceedings of the National Academy of Sciences say that these ants gobbled up the native ants, which can be ten times their size. The newcomers then had no choice but to carbo-load, switching over to such sweet treats as honeydew nectar produced by aphids. The ants, which are believed to have arrived in California on ships carrying coffee and sugar from Argentina in the 1890s, have caused problems for big creatures as well. The coastal horned lizard, which dined on domestic ants, has declined in numbers by about half recently.  Apparently because the lizard doesn’t particularly care for Argentinian food.
