New research from the University of Notre Dame is shedding light on the unexpected effects climate change could have on regional instability and violent conflict.
Previous studies have linked drought to instances of intense conflict. As climate change is expected to bring hotter, dryer conditions to certain regions around the world, with it has come the expectation that conflict, too, will rise.
But this notion is more nuanced, according to the Notre Dame study, published in the Proceedings of the National Academy of Sciences.
The number of political candidate television advertisements that refer to guns increased significantly across four election cycles in U.S. media markets, according to a new study led by researchers at the Johns Hopkins Bloomberg School of Public Health.
An international team of researchers has discovered the hydrogen atoms in a metal hydride material are much more tightly spaced than had been predicted for decades--a feature that could possibly facilitate superconductivity at or near room temperature and pressure.
Such a superconducting material, carrying electricity without any energy loss due to resistance, would revolutionize energy efficiency in a broad range of consumer and industrial applications.
HAMILTON, Feb. 3, 2020 - A collaboration between McMaster and Harvard researchers has generated a new platform in which light beams communicate with one another through solid matter, establishing the foundation to explore a new form of computing.
Their work is described in a paper published today in the Proceedings of the National Academy of Sciences.
A new Scientific Reports paper puts an evolutionary twist on a classic question. Instead of asking why we get cancer, Leonardo Oña of Osnabrück University and Michael Lachmann of the Santa Fe Institute use signaling theory to explore how our bodies have evolved to keep us from getting more cancer.
NASA's Terra satellite saw yet another fire, known as the Orroral Valley Fire, break out in the Canberra region of Australia, specifically in and around the ?Namadgi National Park. In one week, these fires have consumed 62,988 hectares (155,646 acres) according to the Australian Capital Territory Emergency Services Agency as of Feb. 04, 2020 (2:30 am local Australian time). The Department of Defence in Australia has reported that a firefighting helicopter's landing lights created the heat needed to spark the new fire.
After the Big Bang, there likely came a period of inflation where the universe rapidly expanded. As this rapid expansion ends, incredibly dense quantum matter--called a condensate--is expected to form. However, even if this condensate is long-lived, interactions between it and its own gravitational field ultimately cause it to fragment. Now, scientists have created the first simulation of the condensate during this process. Musoke et al. modeled the matter's fragmentation to provide the first quantitative examination of the gravitational disintegration of the condensate.
Scientists at Caltech and JPL have tied a shift in winter weather patterns in Europe and northern Eurasia to a reduction in air pollution.
A year-round acoustic study of marine mammals in the northern Bering Sea is providing scientists with a valuable snapshot of an Arctic world already under drastic pressure from climate change, according to WCS (Wildlife Conservation Society), Columbia University, Southall Environmental Associates, and the University of Washington.
Using results of a survey of more than 2,700 self-reported users of the herbal supplement kratom, sold online and in smoke shops around the U.S., Johns Hopkins Medicine researchers conclude that the psychoactive compound somewhat similar to opioids likely has a lower rate of harm than prescription opioids for treating pain, anxiety, depression and addiction.
Renewed investments in hydrogen fuel cell technologies and infrastructure by companies like Amazon; nations like China; and automakers like Toyota, Honda, and Hyundai, are sparking sales and fresh interest in the vast possibilities of polymer-electrolyte fuel cells. The fresh interest could revolutionize transportation and fill streets with vehicles whose only effluent is water vapor.
Young girls who are about to undergo treatment for cancer or other therapies that pose high risk of infertility can opt to have an ovary removed and preserved for future transplantation when they are ready to pursue pregnancy. However, the tiny ovary can be easily damaged during surgery and the quality of ovarian tissue for fertility preservation is affected by the surgical removal technique, according to a study from Ann & Robert H. Lurie Children's Hospital of Chicago published in the Journal of Pediatric Surgery.
Every year, about 8 million metric tons of plastic are put into the world's oceans. Of particular concern are microplastics, materials found in the marine environment that occur in sizes below five millimeters and are the most abundant form of marine debris observed at the ocean surface.
In the first national study of its size, researchers at University of California San Diego School of Medicine and UC San Diego Health, Department of Nursing, have found that male and female nurses are at higher risk of suicide than the general population. Results of the longitudinal study were published in the February 3, 2020 online edition of WORLDviews on Evidence Based-Nursing.
An Australian study examining the relationship between flexibility and parent health has revealed formal family-friendly workplace provisions alone are not meeting the demands of working mothers and fathers.
The La Trobe University survey of more than 4,000 parents from different occupations found 86 per cent relied on additional informal 'catch-up' strategies to manage work-family responsibilities on a daily-to-weekly basis.
