Semi-volatile organic compounds can readily diffuse into the billions of tiny atmospheric particles that inhabit the air, easily moving among them, researchers have discovered. The findings provide greater understanding into how organic particles behave in the atmosphere.
For the first time scientists can see how the shells of tiny marine organisms grow atom-by-atom, a new study reports. The advance provides new insights into the mechanisms of biomineralization and will improve our understanding of environmental change in Earth's past.
Patients may be more likely to take their regularly prescribed medications for chronic conditions such as diabetes and hypertension correctly before surgery when provided a simple instruction sheet, reveals a study. Taking medication correctly before surgery can improve patient safety and comfort, and reduce day-of-surgery cancellations.
New guidelines for discontinuing mechanical ventilation in critically ill adults have been published by researchers. The goal of the guidelines is to help physicians and other health care professionals determine when patients with acute respiratory failure can breathe on their own and to provide clinical advice that may increase the chances for successful extubation.
The majority of women who chose nitrous oxide (laughing gas) to manage labor pain, ultimately decide to have an epidural, according to new research. Investigators found nitrous oxide provided limited pain relief, with patients reporting no change in average pain scores after its use.
A novel coating they made with antibiotic-releasing nanofibers has the potential to better prevent at least some serious bacterial infections related to total joint replacement surgery, scientists show in a proof-of-concept study with mice.
A family of small RNA molecules affects the development of cells that give rise to the placenta -- an organ that transfers oxygen and nutrients from mother to fetus -- in ways that could contribute to a serious pregnancy complication, researchers report.
A microbe that ‘eats’ both methane and iron: microbiologists have long suspected its existence, but were not able to find it - until now. Researchers have discovered a microorganism that couples the reduction of iron to methane oxidation, and could thus be relevant in controlling greenhouse gas emissions worldwide.
For many people, nanotechnology belongs in the realm of science fiction. Researchers have solved the mystery of the blue sheen on the leaves of some begonias and have found that their chloroplasts have evolved a nanoscale light-trapping structure to help them survive in the darkness of the forest floor.
The proportion of cancer deaths attributable to cigarette smoking varied across the United States but was highest in the South, where nearly 40 percent of cancer deaths in men were estimated to be connected to smoking in some states, according to a new article.
