Stag Beetles Mating
This short video gives excellent real life, close up footage of a pair of Stag Beetles mating. The stag beetle (Lucanus cervus) is arguably the most spectacular looking beetle in Britain; the male looks like something from a prehistoric age. The giant antler-like mandiblesare used in courtship displays, and wrestling with other males. Although rather fearsome in appearance, the mandibles cannot be closed with any force. You are more likely to be nipped sharply by the female s

Spiders Jump With Deadly Accuracy in Green Light
Researchers have discovered a unique visual attribute that jumping spiders use in attacking and catching prey. The arachnids use what is called image defocus-proven in part by videos that show spiders jumping with deadly accuracy in green light (and fumbling in red).

Writing and Experience: Crossing Borders, Fall 2010
In this era of globalization, many of us have multi- or bi-cultural, multilingual or bilingual backgrounds, and even if we don't have such a background, we need urgently to understand the experiences of people who do.
