Invasive, Exotic, Aquatic and Wetland Plants in the Western United Sta
Information about over a dozen plants that cause problems in wetlands in the western United States. Includes descriptions, images, and information about economic importance, distribution, habitat, history, and response to control methods for plants such as smooth cordgrass and Brazilian elodea. From the Western Aquatic Plant Management Society. Musician In The Mirror: New Study Shows Brain Rapidly Forms Link Betwe
A new imaging study shows that when we learn a new action with associated sounds, the brain quickly makes links between regions responsible for performing the action and those associated with the sound. 'Underground' Tunnels Discovered As Means For Communication Between Im
Immune system cells are connected to each other by an extensive network of tiny tunnels that, like a building's hidden pneumatic tube system, are used to shoot signals to distant cells. This surprising discovery, being reported by University of Pittsburgh researchers, may explain how an immune response can be so exquisitely swift. The research proves cells other than neurons are capable of long-distance communication and reveals a hereto-unknown mechanism cells use for exchanging information. Record-breaking Hydrogen Storage Materials For Use In Fuel Cells Devel
Scientists have discovered a new class of hydrogen storage materials that could make the storage and transportation of energy much more efficient -- and affordable -- through higher-performing hydrogen fuel cells. Global Nuclear Disarmament Fund: "Full Circle"-- The Epic Return to Tr
"Almost 60 years ago a flame was kindled from the embers of the City of Hiroshima after the ... first atomic bomb was dropped."This site describes how in July and August 2005 Zen monks will walk, carrying this "atomic flame,"from San Francisco to the Trinity Test Site in Alamogordo, New Mexico (location of the first atomic bomb detonation), where the flame will be extinguished. Includes a route map and schedule. Also in Japanese. Marine Scientists Warn Human Safety, Prosperity Depend On Better Ocean
Marine scientists say warming seas, over-fishing and pollution are among profound concerns that must be better measured to help society respond in a well-informed, timely and cost-effective way. Cost of an initial adequate system would require a further investment estimated at $2-3 billion. Speedy diagnosis of the temper and vital signs of the oceans matters increasingly to the well being of humanity, say scientists urging support to complete a world marine monitoring system within 10 years. Heart Damage Can Be Reversed with Early Treatment
Researchers have discovered that treating people who have early cardiovascular abnormalities, but show no symptoms of cardiovascular disease, can slow progression and even reverse damage to the heart and blood vessels. In a recent double-blind study, researchers enrolled 76 asymptomatic subjects with early markers for cardiovascular disease, based on a 10-factor scale called the Rasmussen Disease Score. During the first six months of the study, 38 subjects received a placebo, and the other 38 subjects took 160mg of Valsartan, a drug that blocks a hormone that is detrimental to the blood vessels and the heart. How Well Do Dogs See At Night?
Dogs see a lot better than humans do at night. Dogs have many adaptations for low-light vision. A larger pupil lets in more light. The center of the retina has more of the light-sensitive cells (rods), which work better in dim light than the color-detecting cones. Children's Memory Of Long-ago Events May Be More Accurate Than Previou
Research with 5- and 6-year olds indicates that children's memories can be accurate even when interviewed well after an event. A long delay (three versus twenty one days), had no effect on the accuracy of children's memory of certain activities. The researchers observed differences in memory depending on how much the details varied each time the activity took place. These findings have implications for interviewing child witnesses who are interviewed a while after an incident. Nebraska Toy Stories
Website companion to an exhibit at the Museum of Nebraska History that "showcased a selection of toys dating from the 1860s through the 1960s grouped by theme."Provides images of some of the exhibit items, such as building blocks, marbles, tin planes and cars, dolls and dollhouses, and rocking horses.
