Phoenix, Arizona, USA: For iconic landscapes such as Grand Canyon or the Appalachian Mountains, geological features are an integral part of their appeal. Yet despite the seeming permanence of cliffs, caves, fossils, and other geological highlights, these features are surprisingly vulnerable to damage or destruction. Across the U.S., there is a growing awareness that America's geological resources represent a common heritage that needs to be preserved--and that doing so can yield considerable economic and societal benefits.
Phoenix, Arizona, USA: Etched onto the steep walls of Arizona's 6,000-foot-deep, 277-mile-long Grand Canyon are clues that chronicle the sweeping changes the region has experienced during the past two billion years. The canyon's colorful layers narrate tales of ancient environments come and gone, from lofty mountain ranges and tropical seas to a Saharan-scale desert that once stretched across much of western North America.
TAMPA, Fla. (September 23, 2019)- Older individuals and those with chronic conditions are especially at risk following natural disasters. Researchers at the University of South Florida (USF) investigated the short- and long-term effects of Hurricanes Katrina and Rita on older individuals with diabetes. They found those who lived in areas impacted by the 2005 hurricanes had a 40% higher one-month mortality rate than those who lived in unaffected counties. The increased risk persisted even ten years later, at which point the affected individuals had a 6% higher mortality rate.
MADISON, WIS. - The Affordable Care Act (ACA) provided health insurance for an estimated 1.9 million people with diabetes, according to a newly published study.
In 2009 and 2010, 17 percent of adults who were under the age of 65 and had diabetes were uninsured. After the ACA took effect, that percentage declined by 12 percentage points and by 27 percentage points among those with low income.
"Like a book in which the single pages are not all different but carry small portions of common text, or like a group of people who whistle a very similar tune": this is how our brain cells work, say scientists. It is the phenomenon of "co-relation", in which individual neurons do not always act as independent units in receiving and transmitting information but as a group of individuals with similar and simultaneous actions.
The Karla crater, one of the about 150 large impact structures on Earth, is situated near the border of the Republic of Tatarstan and Chuvash Republic, about 163 kilometers from Kazan Federal University.
Previous research there took place in the 1980s. This time, Russian and French scientists conducted new inquiries.
Scientists at the University of Surrey have discovered that a natural antioxidant commonly found in green tea can help eliminate antibiotic resistant bacteria.
The study, published in the Journal of Medical Microbiology, found that epigallocatechin (EGCG) can restore the activity of aztreonam, an antibiotic commonly used to treat infections caused by the bacterial pathogen Pseudomonas aeruginosa.
UNIVERSITY PARK, Pa. -- A new artificial intelligence (AI) tool available for free in a smartphone app can predict near-term crop productivity for farmers in Africa and may help them protect their staple crops -- such as maize, cassava and beans -- in the face of climate warming, according to Penn State researchers. The team will unveil the new tool -- which will work with their existing AI assistant, called "PlantVillage Nuru" -- to coincide with the United Nations Climate Action Summit to be held today (Sept. 23) at the U.N. Headquarters in New York City.
ANN ARBOR--When University of Michigan wildlife ecologist Nyeema Harris started her multiyear camera survey of West African wildlife, she sought to understand interactions between mammals and people in protected areas such as national parks.
She expected those interactions to include lots of poaching. Instead, livestock grazing and the gathering of forest products were among the most common human-related activities her cameras captured, while poaching was actually the rarest.
Phoenix, Arizona, USA: For more than a century, a guiding principle in seismology has been that earthquakes recur at semi-regular intervals according to a "seismic cycle." In this model, strain that gradually accumulates along a locked fault is completely released in a large earthquake. Recently, however, seismologists have realized that earthquakes often occur in clusters separated by gaps, and one research group now argues that the probability of a tremor's recurrence depends upon whether a cluster is ongoing -- or over.
A recent analysis from Canada found that information on health-related quality of life is often not collected for investigational cancer drugs or used to calculate the balance of costs and benefits of these drugs when they are submitted for reimbursement, according to findings published early online in CANCER, a peer-reviewed journal of the American Cancer Society.
The population of threatened southern sea otters in Elkhorn Slough, an estuary in Central California, has made a significant comeback as a result of Monterey Bay Aquarium's Sea Otter Program.
PHILADELPHIA - Researchers from the Perelman School of Medicine at the University of Pennsylvania have developed a vaccine to protect against genital herpes. Tested on both mice and guinea pigs, the immunization led to "mostly sterilizing immunity" from the virus--the strongest type of immunity. The results of the study are published today in Science Immunology.
Alexandria, VA, USA - On September 14, 2018 AADR held the "Oral Health Effects of Tobacco Products: Science and Regulatory Policy" meeting in Bethesda, Maryland, USA. The papers resulting from this conference are published in the latest issue of Advances in Dental Research, an e-Supplement to the Journal of Dental Research (JDR).
As part of an international research group based at the Smithsonian Museum of Natural History, anthropology assistant professor Amelia Villaseñor contributed to a large, multi-institutional study explaining how the human-influenced mass extinction of giant carnivores and herbivores of North America fundamentally changed the biodiversity and landscape of the continent.
