A Syracuse University professor has demonstrated that ammonium -- an odiferous chemical compound, often used in fertilizer -- was a vital source of nitrogen for early life on Earth.
A new study from researchers at the University of Cincinnati and Cincinnati Children's Hospital Medical Center looks at the correlation between exposure to traffic-related air pollution (TRAP) and childhood anxiety, by looking at the altered neurochemistry in pre-adolescents.
Andrea becomes the first subtropical storm for the 2019 season although we are two weeks short of the official start date of June 1, 2019. This storm was first spotted on Monday, May 20, 2019 forming over the western Atlantic.
A group of UK and Peruvian researchers have carried out the first detailed study of how rural communities interact with peatlands in the Peruvian Amazon, a landscape that is one of the world's largest stores of carbon.
The warming of the Earth by the human-caused greenhouse effect is progressing. But predictions for the next decades still show relatively large uncertainties. A German-Australian research team headed by GEOMAR Helmholtz Centre for Ocean Research Kiel identified the large natural variations in the tropical Pacific region as the key reason. As a conclusion of their study, published in the renowned scientific journal Nature Communications, the scientists call for more climate data from this region.
In Mexicali, Mexico, an uncontrolled epidemic of Rocky Mountain spotted fever, one of the deadliest tickborne diseases in the Americas, has affected more than 1,000 people since 2008. A binational team of researchers led by the University of California, Davis, has conducted the first comprehensive study to examine risk factors for the disease in Mexicali. Researchers examined dogs, ticks, and surveyed households in 200 neighborhoods.
Researchers in Brazil find that high levels of heavy metals and particulate matter suspended in the atmosphere restrict the growth of tipuana trees, which are ubiquitous in São Paulo, the largest Brazilian city.
The University of Wisconsin-Madison's Monica Turner and her team describe what happens when Yellowstone -- adapted to recurring fires every 100 to 300 years -- instead burns twice in fewer than 30 years. Yellowstone as we know it faces an uncertain future, the researchers say, and one of the big questions they hope to answer is whether the forests can recover.
Governments seeking to help their most vulnerable residents prepare for hurricanes and other disasters should create community-based information campaigns ahead of time, according to a Rutgers study of economically disadvantaged New Jerseyans in the areas hardest hit by Superstorm Sandy.
Anthropologists discovered a tool made out of high-quality translucent jadeite with an intact rosewood handle at a site where the ancient Maya processed salt in Belize. The discovery of these high-quality materials -- jadeite and rosewood -- used as utilitarian tools, demonstrates that salt workers played an important role in the Classic Maya marketplace economy more than 1,000 years ago.
