In a 'seismological wind tunnel,' engineers demonstrate the impact of rock gouge -- ground-up rock along a fault boundary -- on earthquake propogation.
Data Reveal 20-Year Transformation of Gulf of Maine
A new synthesis of two decades of data has elucidated the startling transformation of the warming Gulf of Maine.
Lessons From the Past: How Cold-Water Corals Respond to Global Warming
Cold-water corals, and the species Lophelia pertusa in particular, are the architects of complex reef structures.
Scientists find new indicators of Alaska permafrost thawing
More areas of year-round unfrozen ground have begun dotting Interior and Northwest Alaska and will continue to increase in extent due to climate change, according to new research.
UAF Scientists Find New Indicators of Alaska Permafrost Thawing
More areas of year-round unfrozen ground have begun dotting Interior and Northwest Alaska and will continue to increase in extent due to climate change, according to new research by University of Alaska Fairbanks Geophysical Institute scientists.
Targeted micronutrition ameliorates allergy symptoms
Micronutrient deficiencies can promote inflammation and render the immune system particularly sensitive to allergenic substances. In particular, iron deficiency signals danger to immune cells and leads to a more pronounced, exaggerated immune response. For the first time, scientists have conducted a placebo-controlled trial and showed that targeted dietary measures can...
Nano-sensor detects pesticides on fruit in minutes
Researchers have developed a tiny sensor for detecting pesticides on fruit in just a few minutes. The technique uses flame-sprayed nanoparticles made from silver to increase the signal of chemicals. While still at an early stage, the researchers hope these nano-sensors could help uncover food pesticides before consumption.
Bacterial cellulose could enable microbial life on Mars
An international research team has investigated the chances of survival of kombucha cultures under Mars-like conditions. Kombucha is known as a drink, sometimes called tea fungus or mushroom tea, which is produced by fermenting sugared tea using kombucha cultures -- a symbiotic culture of bacteria and yeast. Although the simulated...
Gene variation may be early indicator for gastric cancer
Researchers are hoping to catch stomach cancer before it develops in at-risk patients. Researchers identified a genetic variation that could help identify when patients with Helicobacter pylori are more likely to develop stomach cancer.
Study explores the promises and pitfalls of evolutionary genomics
A new study examines mathematical models designed to draw inferences about how evolution operates at the level of populations of organisms. The study concludes that such models must be constructed with the greatest care, avoiding unwarranted initial assumptions, weighing the quality of existing knowledge and remaining open to alternate explanations.
