Karen’s knees and elbows are red and scaly. Her mother helps her bathe and moisturize with her favorite cream every day after breakfast and every night before bedtime.

She has to visit her dermatologist (a physician who specializes in the skin) once a month for an ultraviolet light treatment. She resents the time her skin care takes and is afraid that it may be this way all her life.

In 1988, astronauts aboard the space shuttle looked down on South America and saw a 1,000-kilometer-long smoke cloud that covered the entire Amazon basin and was only stopped by the towering wall of the Andes mountains. The haze of smoke came from the burning of the Amazon rain forest, a region containing the world’s greatest variety of plants and animals. That vast spread of smoke was clearly visible to the astronauts, who were in a unique position to see how and where humans are altering natural ecosystems on planet Earth.
That is precisely what scientists plan to learn by using space to take an inventory of natural resources and …
Stay out of the sun! It’s bad for your health! There are a lot of words of caution being spoken these days about overexposure to the sun, and they should be taken seriously.

You can get vitamin D from some foods, but up to 84 percent of …
Do you remember the last time your body, all by itself, decided it had something to say?
Was it in algebra class, while you stood in front of the class at the blackboard solving a complicated problem? Your stomach decided it was just the right time for a long, low growl.
How about that time in the theater, when a master blast from your intestines broke the silence?
Then there was that memorable moment in the lunchroom when a run of hiccups took on a life of its own.
By the way, did you play the starring role in a movie called “Burps in the Library, Part III”?
Yes, we’ve …

Any bone in the body, including the tiny bones in the ear, can be fractured, and the most common causes are failing, auto accidents and sports injuries.
Bones can fracture in different ways as a result of a blow, sudden forceful muscle contraction, or prolonged muscular stress.

If you could design your own personality, would you rather be lively, outgoing, and the center of attention, or quiet, thoughtful, and private?
It would not be surprising if you opted for the first description. You would have lots of company. According to some estimates, there are three times as many lively extroverts in the United States as reflective introvers. Our society prefers fun-loving, friendly people with “good personalities” over quiet, private types.
Is one style really better than the other? Do we have a choice?
Psychiatrist Carl Jung first proposed the theory of personality types in the 1920s. He said we all have two different ways of …
