Optoelectronics To Increase The Broadband Flow
The broadband boom is creating an ever-increasing demand for more capacity and higher rates of data transfer on both fixed-line and wireless networks. Helping to meet that demand, without the need to lay costly new infrastructure, is the LABELS project. Pirate Soul: History
This attractive site includes an overview of piracy, covering history from the 14th century B.C. to the 19th century, notable pirates (Blackbeard, Kidd, Black Bart, and others), pirates' codes of conduct and other aspects of pirate life, weapons and treasure, and the Jolly Roger. From the Pirate Soul Museum in Key West, Florida. Weight is a prickly problem: Key role found for hedgehog signaling in
Obesity is a widespread condition in humans and has many serious consequences. Not only are overweight people faced with surcharges on airplanes but they also have a much higher risk of contracting a number of potentially fatal diseases. A considerable amount of research effort is currently focussed on the problem of weight control but to date genetic screens for factors that cause obesity have been hampered by the lack of an appropriate system. Gene Profiling Predicts Resistance To Breast Cancer Drug Herceptin
Using gene chips to profile tumors before treatment, researchers at Harvard and Yale Universities found markers that identified breast cancer subtypes resistant to Herceptin, the primary treatment for HER2-positive breast cancer. They say this advance could help further refine therapy for the 25 to 30 percent of breast cancer patients with this class of tumor. Consequences of a Rising Bay/Global Warming: New Set of Maps Reveals H
These February 2007 maps, "which the Bay Conservation and Development Commission prepared for The Chronicle, offer a detailed look at how a changing shoreline would affect life around the [San Francisco] bay."Includes a map showing current shoreline and potential shoreline if bay rises one meter, and detailed maps for specific areas, such as Oakland Airport and the South Bay. Also includes link to related article. From SFGate.com, website for the San Francisco Chronicle. Radiologists Encouraged To Look Beyond Cancer For Clinically Unseen Di
Radiologists can diagnose venous thromboembolic disease in cancer patients earlier by looking more carefully at CT scans of the thorax, abdomen and pelvis which are regularly done to determine the extent or stage of the cancer, according to a recent study. [Funny] A referee has sent himself off in an English amateur league ma
Andy Wain had to abandon the Sunday league match between Peterborough North End and a Royal Mail side in the 63rd minute after throwing down his whistle and marching up to confront North End's keeper. Biodiversity Of Southernmost Forests And Tundra Ecosystems
Taxonomists, ecologists and philosophers explored the world's southernmost forest and tundra ecosystems to estimate the diversity of the dominant vegetation, namely tiny bryophytes and lichens. Much of today's conservation strategies focus on "charismatic mega fauna"such as pandas, tigers, and whales; or on vascular plants such as giant redwoods and orchids. Helping In A Selfish World: Fishing For Answers To The Co-operation Qu
Billions of people tuned into recent Live 8 concerts. What makes some of us look out for each other, while others look out for themselves? Traditionally, scientists have explained co-operation using kin selection. Help to relatives makes sense if it means your relative will have more children who will carry your genes into the next generation. However, McMaster University researchers show that in certain situations the reverse is true: unrelated individuals help more. Breakthrough Uses Light To Manipulate Cell Movement
Scientists have developed a technique that uses light to control protein behavior in cells and animals simply by shining light on the cells where they want the protein to be active.
