People-powered 'Crowd Farm?'Plan Would Harvest Energy Of Human Movemen
Two graduate students want to harvest the energy of human movement in urban settings, like commuters in a train station or fans at a concert. The so-called "Crowd Farm"would turn the mechanical energy of people walking or jumping into a source of electricity. A Crowd Farm in Boston's South Station railway terminal would work like this: A responsive sub-flooring system made up of blocks that depress slightly under the force of human steps would be installed beneath the station's main lobby. The slippage of the blocks against one another as people walked would generate power through the principle of the dynamo, a device that converts the energy of motion into that of an electric current. Cardiac Deaths Peak In Sleep Hours For Patients With Sleep Apnea
The 20 million Americans who have obstructive sleep apnea (OSA) are more likely to die suddenly of cardiac causes between 10 p.m. and 6 a.m. than during the other 16 hours of the day combined, according to findings of a Mayo Clinic study published this week in the New England Journal of Medicine. Sleep Problems -- Real And Perceived -- Get In The Way Of Alcoholism R
The first few months of recovery from an alcohol problem are hard enough, and they're often made worse by serious sleep problems. Now, a new study gives further evidence that insomnia and other sleep woes may actually get in the way of recovery from alcohol problems. Navdanya: Seed Sovereignty
Introduction to the seed-related activities of this organization (based in New Delhi, India) founded by scientist and environmentalist Dr. Vandana Shiva. Topics include techniques for seed saving (collection and storage of seeds for future use), the role of "beej rakshaks"(seed keepers), and political actions in India. The "Food sovereignty"section of this website contains additional information about crop diversity. Leading-edge Body Sensor Could Help Produce Sporting Champions
A revolutionary unobtrusive sensor that collects and immediately transmits data from the human body could boost an athlete's sporting success in future. Cufflink-sized and clipped behind the wearer's ear, the sensor is unique in two key respects. First, it does not hinder performance, yet can gather unprecedentedly wide-ranging and useful data about posture, stride length, step frequency, acceleration, response to shock waves travelling through the body etc. Second, when worn by an athlete during training, it can transmit the information for immediate visual display on a handheld device or laptop used by their coach at the trackside. A Potential Anti-prion Drug With 'Unprecedented' Potency
The urgent search for a medication to treat prion diseases has led scientists in Germany to synthesize a new group of compounds, including one that is 15 times more potent than an approved drug now being tested in clinical trials. Their report is scheduled for the Nov. 2 issue of the biweekly ACS Journal of Medicinal Chemistry. National Park Service: Park Histories
A collection of dozens of long and detailed histories of the national parks of the United States, written by National Park Service (NPS) staff. Arranged by name of the park. Opening And Closing The Genome: Newly Identified Enzyme Orchestrates A
A dynamic cast of gatekeeper enzymes controls access to the DNA for gene transcription, adding and removing particular molecules to open or close the genome as needed. Researchers have identified an important new player in this gene-control system, an enzyme responsible for removing certain molecules, or marks, involved in opening or closing chromatin, the material that makes up chromosomes. The activity of this enzyme is thought to be widespread, likely affecting many genes. Mars Express Evidence For Large Aquifers On Early Mars
Substantial quantities of liquid water must have been stably present in the early history of Mars. The findings of OMEGA, on board ESA's Mars Express, have implications on the climatic history of the planet and the question of its 'habitability' at some point in its history. 1918 Influenza Pandemic
"In 1918, a highly virulent form of the influenza virus [known as the 'Spanish Flu'] killed at least 20 million people worldwide."This site features information about an October 2005 report that scientists in the U.S. reconstructed the 1918 flu virus. Includes links to related articles, some of which are only available to subscribers. From Nature magazine.
