In search of key blue ingredient in ancient Egyptian pottery
03/16/2010 - 23:00
As one of the "generic geologists" on a dig called the Dakhleh Oasis Project, associate professor Jennifer Smith was asked to sample the alum from ancient mines and to determine whether it could be the source of the blue in the "blue painted pottery" found at sites dating from the New Kingdom. It was a small question but an intriguing one.

An organic approach to pest control: releasing super-sexed (but sterile) male insects
03/16/2010 - 23:00
An improved method for sustainable pest control using "super-sexed" but sterile male insects to copulate with female ones is being developed by agricultural researchers in Israel. The scientists thus hope to offer yet another efficient and promising avenue for supplying produce to the market by eliminating pests without damage to the environment.

A team of Spanish researchers has studied the diet of three species of sharks living in the deep waters in the area of El Cachucho, the first Protected Marine Area in Spain, which is located in the Cantabrian Sea off the coast of Asturias. These animals feed on the resources available in their environment, according to changes taking place in the ocean depths.

Chemicals that eased one environmental problem may worsen another
03/16/2010 - 22:00
Chemicals that helped solve a global environmental crisis in the 1990s -- the hole in Earth's protective ozone layer -- may be making another problem -- acid rain -- worse, scientists are reporting. A new study analyzes the effect of chemicals that replaced the ozone-destroying chlorofluorocarbons once used in aerosol spray cans, air conditioners, refrigerators, and other products.

UV exposure has increased over the last 30 years, but stabilized since the mid-1990s
03/16/2010 - 16:00
NASA scientists analyzing 30 years of satellite data have found that the amount of ultraviolet radiation reaching Earth's surface has increased markedly over the last three decades. Most of the increase has occurred in the mid-and-high latitudes, and there's been little or no increase in tropical regions.
