Where's the "Head & Shoulders"?

Randolph E. Schmid writes at Technewsworld.com about an article in Science:

Ruprecht Jaenicke of the Institute for Atmospheric Physics at Mainz University in Germany has studied air samples and discovered that biological materials can range up to 25 percent of aerosols in some areas, and as high as 40 percent in others.

A researcher has discovered unexpectedly large amounts of dandruff and other flaking skin, fur, pollen and similar materials in air pollutants known as aerosols.

Aerosols, tiny particles in the air, are widely studied because they are an important factor in regulating climate, variously absorbing heat to warm the air and reflecting sunlight to cool it. They are also important in forming rain and snow.
