The War Relocation Centers of World War II: When Fear Was Stronger tha
A lesson plan designed to study the U.S. government's confinement of people of Japanese ancestry to relocation centers during World War II. Resources include maps, readings, photographs and layouts of the Manzanar (California) and Rowher (Arkansas) camps, activities, and links to related Web sites. From the U.S. National Park Service program, Teaching with Historic Places. Impact On Lungs Of One Cannabis Joint Equal To Up To Five Cigarettes
A single cannabis joint has the same effect on the lungs as smoking up to five cigarettes in one go, indicates new research. Cannabis smokers complained of wheeze, cough, chest tightness and phlegm. But emphysema, the progressive and crippling lung disease, was only seen in those who smoked tobacco, either alone or in combination. But cannabis still damaged the lungs and stopped them from working properly. Nuts Fact Sheets: Chestnuts
Collection of essays about growing chestnut trees in the U.S. Includes essays on a history of the introduction of foreign chestnut trees to the U.S. mainly in the 19th century, how to distinguish American chestnut trees from other chestnuts within the original native range, the spread of the chestnut blight fungus in the early 20th century, and growing chestnuts from seeds. From the Connecticut Agricultural Experiment Station. Scientists Discover The Dynamics Of Transcription In Living Mammalian
Transcription -- the transfer of DNA's genetic information through the synthesis of complementary molecules of messenger RNA -- forms the basis of all cellular activities. Yet little is known about the dynamics of the process -- how efficient it is or how long it takes. Now, researchers have measured the stages of transcription in real time. Their unexpected findings have fundamentally changed the way transcription is understood. Duke Chemists Isolating Individual Molecules Of Toxic Protein In Alzhe
To understand the formation of the brain-clogging deposits that cause such disorders as Alzheimer's and Parkinson's diseases, Duke University chemists have figured out how to capture and "micromanipulate"the single molecular building blocks of the deposits. UN Office of the Special Representative of the Secretary-General for C
Website for this United Nations (UN) office that acts as a "public advocate and moral voice on behalf of children whose rights and wellbeing have been and are being violated in the context of armed conflict."Features overviews of issues such as child soldiers, girls in war, landmines, and displaced children. Also includes background documents, reports, photos, videos, conference details, press releases, and more. What Makes Quantum Dots Blink?
In order to learn more about the origins of quantum dot blinking, researchers have developed a method to characterize it on faster time scales than have previously been accessed. Nanocrystals of semiconductor material, also known as quantum dots, are being intensively investigated for applications such as light-emitting diodes, solid-state lighting, lasers, and solar cells. Experts Identify Products That Cause Greatest Environmental Damage
Cutting-edge research identifying the types of products that cause the greatest environmental damage is the focus of a special issue of Yale's Journal of Industrial Ecology. Echinoderms contribute to global carbon sink; impact of marine creatur
The impact on levels of carbon dioxide in the Earth's atmosphere by the decaying remains of a group of marine creatures that includes starfish and sea urchin has been significantly underestimated. Researchers Develop New Method For Studying 'Mental Time Travel'
Princeton neuroscientists have developed a new way of tracking people's mental state as they think back to previous events -- a process that has been described as "mental time travel."The findings, detailed in the Dec. 23 issue of Science, will aid efforts to learn more about how people mine the recesses of memory and could have a wide-ranging impact in the field of neuroscience, including studies of brain disorders such as Alzheimer's disease.
