The Wildlife Conservation Society (WCS) announced the discovery of a huge population of rare dolphins in South Asia. Using rigorous scientific techniques, WCS researchers estimate that nearly 6,000 Irrawaddy dolphins, which are related to orcas or killer whales, were found living in freshwater regions of Bangladeshâ’s Sundarbans mangrove forest and adjacent waters of the Bay of Bengalâ”an area where little marine mammal research has taken place up to this point. Prior to this study, the largest known populations of Irrawaddy dolphins numbered in the low hundreds or less. â’With all the news about freshwater environments and state of the...

Star Trek Becoming Reality : Beam Me Up Scotty
First it is remote controls, robot wars, stun guns, laser beams, fancy jumpsuit uniforms and now teleportation. For the first time, scientists have successfully teleported information between two separate atoms in unconnected enclosures a meter apart â’“ a significant milestone in the global quest for practical quantum information processing. A team from the Joint Quantum Institute (JQI) at the University of Maryland and the University of Michigan has succeeded in teleporting a quantum state directly from one atom to another over a substantial distance. That capability is necessary for workable quantum information systems because they will require memory storage...
Cavities :: Men vs Women
Answer : Women Reproduction pressures and rising fertility explain why women suffered a more rapid decline in dental health than did men as humans transitioned from hunter-and-gatherers to farmers and more sedentary pursuits, says a University of Oregon anthropologist. The conclusion follows a comprehensive review of records of the frequencies of dental cavities in both prehistoric and living human populations from research done around the world. A driving factor was dramatic changes in female-specific hormones, reports John R. Lukacs, a professor of anthropology who specializes in dental, skeletal and nutritional issues. His conclusions are outlined in the October issue...
