Why Do Autumn Leaves Turn Red? Soil May Dictate Fall Colors
Soils may dictate the array of fall colors as much as the trees rooted in them, according to a forest survey out of North Carolina. By taking careful stock and laboratory analyses of the autumn foliage of sweetgum and red maple trees along transects from floodplains to ridge-tops in a nature preserve in Charlotte, N.C., scientists found that in places where the soil was relatively low in nitrogen and other essential elements, trees produced more red pigments known as anthocyanins.

This new study adds insight into the migration of anatomically modern humans out of Africa and into Asia less than 100,000 years before present. The comprehensive review of human genetic, environmental and archaeological data from the circum-Pacific region supports the hypothesis that modern humans migrated into eastern Asia via a southern coastal route.

Sufferers of electromagnetic field sensitivity claim that the growing pervasiveness of wireless networks only exacerbates their condition. Skeptics discount their fears -- and their symptoms -- and the battle is joined. By Rob Beschizza. Controlling Soil Erosion
Soil erosion from rain and wind produces water quality issues in streams, rivers and lakes, degrades soil quality, and affects human health. Now an environmentally-friendly solution called WoodStraw, an innovative erosion control material made from sliced strands of wood that is tailor-made for use on forests, highway projects, watersheds and other natural areas has been developed. Previous erosion control methods, specifically the use of straw, were hampered by lack of stability under windy conditions, possible introduction of noxious weeds, chemical residue from pesticides and short-lived performance. WoodStraw is heavier than straw, making it less likely to be blown away when exposed to high winds. Firefighters Keep From Broiling With the Rosenbauer Water-Atomizing No

The colors of the sunset result from a phenomenon called scattering. Molecules and small particles in the atmosphere change the direction of light rays, causing them to scatter. Scattering affects the color of light coming from the sky, but the details are determined by the wavelength of the light and the size of the particle.
