Herding With Hockey Sticks: Elk Trained To Stay Away From Tourists
There are no hockey sticks waving around on NHL ice this holiday season, but travel to Banff National Park in Alberta, Canada, and you'll see plenty of them. The game? Keeping elk at a safe distance from their adoring fans. The Impeachment Trial of President Andrew Johnson: Supplement to the C
Digitized supplement to the Congressional Globe (the predecessor to the Congressional Record) that provides a record of the documents and debates for the impeachment trial of President Andrew Johnson. Includes an index to the document and links to other Library of Congress resources related to the impeachment of President Johnson and the impeachment process in general. A special presentation from a larger collection of the American Memory Project of the Library of Congress. Alcohol And Cancer: Is Drinking The New Smoking?
Researchers have clarified the link between alcohol consumption and the risk of head and neck cancers, showing that people who stop drinking can significantly reduce their cancer risk. These results have important implications for tailoring alcohol policies and prevention strategies, especially for people with a family risk of cancer. Teenage Depression Can Be Enduring, But Is More Often Short-lived
Teenage depression is widespread and can become a life-long illness, but is more often transitory, said UCLA Psychology Professor Constance Hammen. Adolescent depression can be as high as 20 percent or higher, said Hammen, who has studied depression for more than 30 years. Most of the depressions will be short-lived, but of those who have adolescent depression, perhaps 40 percent will have recurring depression, and many of those will likely be life-long. Great Plains'Historical Stability Vulnerable To Future Changes
A survey of long-term trends in population, farm income and crop production in the agricultural Great Plains finds that technological advances, such as improved crop varieties, irrigation and fertilizer use, have greatly increased production of major crops and allowed rural populations to remain stable over the past 50 years even as metropolitan populations have soared. Yet substantial environmental impacts have resulted, including loss of soil carbon and high nitrate runoff, especially in irrigated areas. Inhaling Helps Heal Liver Transplant Recipients
A new study indicates that one of the main complications of liver transplantation can be treated very simply. Inhalation of nitrous oxide during the transplant operation decreased the length of time patients had to stay in hospital and increased the rate at which the function of the transplanted liver was restored. Sea Otter, Peregrine Falcon Back From The Brink Of Extinction But Othe
There's good news and bad news in the Committee on the Status of Endangered Wildlife in Canada (COSEWIC) report. The good news: The peregrine falcon and the sea otter no longer face extinction. The not-so-good news: COSEWIC proposes adding another 36 species to Canada's official List of Wildlife Species at Risk. Species from all regions of the country, on the land and in the sea, are at risk of extinction. Personality Traits And Craving Among Pathological Gamblers And Alcohol
Addiction-related "craving"can be physical, as in withdrawal, and/or memory-based, as in desire. A new study compares craving between pathological gamblers and alcoholics, correlating craving with personality. Results show that gamblers and alcoholics have distinctive personality traits that affect their cravings. Quitting Smoking: Genetic Research Shows Promise For Personalized Trea
New genotyping research from the Center for Addiction and Mental Health found that the enzyme known to metabolize both the smoking cessation drug bupropion and nicotine is highly genetically variable in all ethnicities and influences smoking cessation. This finding is a step toward being able to tailor smoking cessation treatment to individuals based on their unique genetic make-up. Hospital Bugs Get From Bottom To Bedrail
The presence of the bacterium Staphylococcus aureus (S. aureus) in patients'stools increases the likelihood that it will make its way onto skin, hospital bed rails and other surfaces, according to new research in BMC Infectious Diseases. The study's most important finding was that patients harbouring S. aureus in both their intestines and noses were significantly more likely than those with this bacterium in their nostrils alone to have the bacterium on their skin.
