Global difference in intelligence is a sensitive topic, long filled with a large number of different opinions. But recent data has indeed shown cognitive (认知的) ability to be higher in some countries than in others. What's more, IQ scores have risen as nations develop --- a phenomenon known as the "Flynn effect". Many causes have been put forward for both the intelligence difference and the Flynn effect, including education, income, and even non-agricultural labor. Now, a new study from researchers at the University of New Mexico offers another interesting theory：intelligence may be linked to infectious-disease rates.

The brain, say author Christopher Eppig and his colleagues, is the "most costly organ in the human body". Brainpower consumes almost up to 90 percent of a newborn's energy. It's clear that if something affects energy intake while the brain is growing, the impact could be long and serious. And for vast parts of the globe, the biggest threat to a child's body -- and therefore brain ---is parasitic (由寄生虫引起的) infection. These illnesses threaten brain development __________. They can directly attack live tissue, which the body must then try every means to replace. They can invade the digestive pipe and block nutritional intake. They can rob the body's cells for their own reproduction. And then there's the energy channeled (输送) to the immune system to fight the infection.

Using data on national "disease burdens" (life years lost due to infectious diseases) and average intelligence scores, the authors found they are closely associated. The countries with the lowest average IQ scores have the highest disease burdens without exception. On the contrary, nations with low disease burdens top the IQ list.

If the study holds water, it could be revolutionary for our understanding of the still-confusing variation in national intelligence scores.

Are you worried by the rising crime rate? If you are, you probably know that your house and possessions are increasingly in danger of suffering from great rise in the cases of burglary(夜盗;抢劫) and attack.

Figures show an ever-increasing crime rate, but it is only too easy to imagine "It will never happen to me"．Unfortunately, statistics show that it really can happen to you and, if you live in a large city, you run twice the risk of being a victim.

Fortunately, there is something definite which you can do．Protect Alarms can help to protect your house with a burglar alarm system which is effective, simple to operate and easily affordable.

You must remember that owning a burglar alarm is no indication(暗示) that your house is packed with valuable possessions．It quite simply indicates to unwelcome visitors that yours is one house they will not break into easily, so they carry on to an unprotected house where their job is made a lot easier.

Almost all theme park accidents can be prevented．Here, based on coverage of theme park safety, are some tips to help you and your family stay safe on your next visit.

If you are visiting with a child, take a moment to explain the ride to them, and tell them what they should do．They are depending upon you to keep them safe．Set a good example for them by following the rules of the park, and make sure that they know you expect them to follow those rules, too.

Tell them to stay seated, to hold the grab bar or put their hands in the laps, and not to stick their knees and feet outside a ride vehicle．Make them look to you for the okay to get on or off a ride, too．And never put a crying child on a ride．If your child starts to cry, let others pass you in line until your child is calmed．Or, gently exit the queue and find something more relaxing to do． 

Young kids can’t keep an adult’s pace in a theme park．Let them take plenty of breaks.

“Kids get tired,” said TPI reader Matt Johnson, a father of four．“Tired kids make parents even more tired．And tired kids and parents may get hurt — physically and emotionally.” He advises that parents plan a mid-day break, perhaps a swim back at the hotel, to avoid mid-day heat and crowds．“You will see cranky families having a miserable time while you are refreshed and having a great evening.”
