Stress related to the coronavirus pandemic and the uncertainty of what the future holds is motivating people to purchase firearms, a trend that may be more prevalent in those who already own firearms, according to a Rutgers study.
The spread of SARS-CoV-2, the coronavirus responsible for the current pandemic outbreak, has been speculated to be linked to short-term and long-term atmospheric pollutants exposure, mainly particulate matters (PMs). It is in fact possible for people living in highly industrialized areas, therefore exposed to higher pollution levels, to show more severe symptoms. Further studies have pointed out that atmospheric pollutants can act as virus carriers and boost pandemic diffusion.
When it comes to introducing new products to the market, crowdfunding has become a hugely popular way for sellers to attract customers.
A new study from the UBC Sauder School of Business shows that people will pay far more for social good items when they're crowdfunded.
Hundreds of thousands of start-ups have successfully pitched their offerings to millions of prospective buyers on sites like Kickstarter and Indiegogo; in fact, according to data from the Pew Research Center, by 2016, 25 per cent of Americans had contributed to a crowdfunded project.
In the transition toward clean, renewable energy, there will still be a need for conventional power sources, like coal and natural gas, to ensure steady power to the grid. Researchers across the world are using unique materials and methods that will make those conventional power sources cleaner through carbon capture technology.
New findings published by Dartmouth researchers are featured in a special issue of Health Services Research--a top journal that reports on original investigations that enhance understanding of the healthcare field and help improve the health of individuals and communities.
The special issue focuses on new research highlighting the role and impact of integrated health systems in the U.S.--a type of organization that has grown dramatically in recent years and includes hospitals and outpatient physician practices.
There is an urgent need for high-energy-density rechargeable batteries to further satisfy the ever-growing demand for electrical energy storage devices. Triggering the O-related anionic redox activities (e.g. typical Li/Na/K-O2 battery, and Li/Na-rich cathodes) have been regarded as the most promising capacity-boosting strategy for batteries. However, the practical realization of Li/Na/K-O2 battery, a gas-open cell architecture, is severely plagued by some gaseous O2-related intrinsic defects.
DALLAS, Dec. 16, 2020 -- Significant racial disparities exist in heart-related problems among pregnant and postpartum women in the United States, with Black women having the highest risk of several serious complications, according to research published today in the Journal of the American Heart Association, an open access journal of the American Heart Association.
Emissions from the operation of buildings hit their highest-ever level in 2019, moving the sector further away from fulfilling its huge potential to slow climate change and contribute significantly to the goals of the Paris Agreement, according to a new report released today.
Animals can fall into an "ecological trap" by altering their behaviour in the "wrong direction" in response to climate change, researchers say.
The so-called "rescue hypothesis" suggests many species might successfully adapt to changing conditions, especially those that are flexible in their behaviour.
But a new study, by the University of Exeter, found that chestnut-crowned babbler birds responded to rising temperatures by changing their behaviour in ways that could actually reduce successful breeding.
The latest consensus meeting of international experts in critical care and nephrology supports the use of novel biomarkers in the prevention and management of Acute Kidney Injury (AKI)
The consensus recommends using a combination of damage and functional biomarkers together with clinical information for routine practice
Proenkephalin (penKid®), the kidney function biomarker, proposed as a marker for the assessment of AKI progression and kidney recovery
Salmonella are bacteria that can cause food poisoning with severe diarrhoea. If they penetrate from the intestine into the blood system, this can lead to sepsis, life-threatening inflammatory reactions in the entire organism. Since salmonellae are also becoming increasingly resistant to antibiotics, new approaches are being sought to combat them.
An international research team, led by scientists from Würzburg, shows how to succeed in this search in the new research journal microLife.
More than 100 new proteins found
Tsukuba, Japan - Researchers at the University of Tsukuba have created a new carbon-based electrical device, π-ion gel transistors (PIGTs), by using an ionic gel made of a conductive polymer. This work may lead to cheaper and more reliable flexible printable electronics.
A team of scientists have solved the longstanding problem of how electrons move together as a group inside cylindrical nanoparticles.
The new research provides an unexpected theoretical breakthrough in the field of electromagnetism, with perspectives for metamaterials research.
The team of theoretical physicists, from the University of Exeter and the University of Strasbourg, created an elegant theory explaining how electrons move collectively in tiny metal nanoparticles shaped like cylinders.
Barchans are crescent-shaped sand dunes whose two horns face in the direction of the fluid flow. They appear in different environments, such as inside water pipes or on river beds, where they take the form of ten-centimeter ripples, and deserts, where they can exceed 100 meters, and the surface of Mars, where they can be a kilometer in length or more. If their size varies greatly, so does the time they take to form and interact. The orders of magnitude range from a minute for small barchans in water to a year for large desert formations and a millennium for the giants on Mars.
"It is about understanding best and worst-case scenarios - and the fact that worst case is one of the most important things to keep track of when navigating through pandemics - regardless whether it be in Denmark, the EU, the USA or the WHO.
