Rubrene crystal raises hope for the use of organic semiconductors and cheaper, more efficient solar cells Rutgers University physicists have found new properties within a material that could lead to the production of less expensive and more efficient plastic solar cells. Vitaly Podzorov, co-author of the study and assistant professor of physics at Rutgers University, along with his research team have discovered that organic semiconductors allow energy-carrying particles -- which are created by "packets" of light -- to journey a thousand times farther than researchers previously thought. "Organic semiconductors are promising for solar cells and other uses, such as video displays, because they can be...

The film of the kidnapping of the 3 IDF soldiers on the Lebanese border in 2000, simulcast in Lebanon and Israel this week, lacks the parts implicating the UN in the affair, says the father of one. Chaim Avraham is the father of Benny Avraham, who was one of the three soldiers kidnapped and murdered by Hizbullah in October 2000. He produced a photograph today further implicating the UN in at least indirect involvement in the violent abduction. Videotapes of the kidnapping, filmed by UNIFIL sources, have long been known to exist, though the UN originally denied it for months....

Jade find in Antigua produces links to Central America Tuesday June 20 2006 A discovery of ancient jade could shake up old notions of the New World before Columbus. Scientists say they have traced 1,500-year-old axe blades found in the eastern Caribbean to ancient jade mines in Central America 1,800 miles (2,900 kilometers) away, New York’s American Museum of Natural History announced late last month. The blades were excavated in the late 90s by a Canadian archaeologist on the island of Antigua in the West Indies But the jade used to make the blades almost certainly came from Maya mines...
