Accuracy Of Diagnostic Mammograms Varies By Radiologist, Study Finds
For women with breast symptoms such as lumps, the ability of diagnostic mammograms to detect breast cancer accurately depends strongly on which radiologist reads them, according to a Group Health study published online on December 11 in the Journal of the National Cancer Institute. Study Shows Bacterium Present In Eyes With 'Wet' Age-related Macular D
Researchers at the Massachusetts Eye and Ear Infirmary (MEEI) have found that Chlamydia pneumoniae, a bacterium linked to heart disease and capable of causing chronic inflammation, was present in the diseased eye tissue of five out of nine people with neovascular, or "wet,"age-related macular degeneration (AMD). Breath Test Offers Hope For Early Detection Of Lung-bacteria Growth In
Breath-analysis testing may prove to be an effective, non-invasive method for detecting the damaging lung-bacteria growth seen in cystic fibrosis, which would allow for early stage treatments that can extend the health of people with this disease, UC Irvine researchers have found. Cancer Stem Cell Subpopulation Drives Metastasis Of Human Pancreatic C
Scientists have identified a distinct subpopulation of cancer stem cells (CSC) that is responsible for metastasis of a deadly human pancreatic cancer. The research provides insight into the role of CSCs in cancer initiation, progression and metastasis, and suggests new directions for development of more effective therapeutics. US Middle School Math Teachers Ill-prepared, Study Finds
Middle school math teachers in the United States are not as well prepared to teach this subject compared to teachers in five other countries, something that could negatively affect the US as it continues to compete on an international scale. Scanning for Deadly Runway Debris
An airport trains its radar on the ground in search of an enemy that can destroy planes: foreign object debris. By John Hudson. Eat Less To Live Longer: Calorie Restriction Linked To Long Healthy Li
For nearly 70 years scientists have known that caloric restriction prolongs life. In everything from yeast to primates, a significant decrease in calories can extend lifespan by as much as one-third. But getting under the hood of the molecular machinery that drives this longevity has remained elusive. Researchers have now discovered two genes in mammalian cells that act as gatekeepers for cellular longevity. When cells experience certain kinds of stress, such as caloric restriction, these genes rev up and help protect cells from diseases of aging. Heat Stress Influences Low Conception Of Dairy Herds
Summer heat stress is a main factor related to low conception rates in high producing dairy herds in warm areas worldwide. A research group studied the impact of several climate variables on conception rates in high producing dairy cows in northeastern Spain by examining 10,964 inseminations. Unemployment And Poverty Remain Dramatically High Among Workers With D
There is a dramatic employment and poverty gap between working-age people with disabilities and those without disabilities. Almost 38 percent of people with disabilities are employed, compared with almost 80 percent of people without disabilities. Environments Resilient In The Face Of Hurricanes, But Questions Remain
The international Estuarine Research Federation (ERF) has announced the publication of a special issue of its scientific journal, Estuaries and Coasts, focused on environmental impacts of hurricanes in coastal areas.Estuaries and Coasts is a bimonthly scientific journal dedicated to dissemination of research about ecosystems at the land-sea interface. The hurricane special edition was published as the journal's December 2006 issue.
