Platinum arguably is the most important electrocatalyst material, not only because it is the best single element catalyst in a variety of important electrocatalytic reactions but also due to its relatively high stability. However, in the corrosive environment of real electrocatalysis systems, such as fuel cells, even platinum can structurally degrade. Moreover, the presence of strongly adsorbing species, in particular carbon monoxide (CO), can substantially increase these degradation effects.
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection can cause acute respiratory distress syndrome, hypercoagulability, hypertension, and multiorgan dysfunction. In recent months, SARS-CoV-2 has gradually spread to more than 200 countries and regions, resulting in more than 500,000 deaths globally.
A study published in the June 2020 edition of the peer-reviewed journal Horticulturae shows that cycads, which are in decline and among the world's most threatened group of plants, provide an important service to their neighboring organisms. The study, completed by researchers from the Western Pacific Tropical Research Center at the University of Guam and the Montgomery Botanical Center in Miami, found that at least two cycad species share nitrogen and carbon through the soil, thereby creating habitable environments for other organisms.
Animal patterns - the stripes, spots and rosettes seen in the wild - are a source of endless fascination, and now researchers at the University Bath have developed a robust mathematical model to explain how one important species, the zebrafish, develops its stripes.
In the animal kingdom, the arrangement of skin pigment cells starts during the embryonic stage of development, making pattern formation an area of keen interest not only for a lay audience but also for scientists - in particular, developmental biologists and mathematicians.
New research demonstrates for the first time that artificial intelligence (AI) can be used to train computers to recognise individual birds, a task humans are unable to do. The research is published in the British Ecological Society journal Methods in Ecology and Evolution.
PHILADELPHIA--While initial reports suggested a significant risk of stroke in patients hospitalized with COVID-19, a new paper published in Stroke from Penn Medicine shows a low risk of stroke in patients hospitalized for COVID-19. Notably, the majority of afflicted patients had existing risk factors, such as high blood pressure and diabetes. These findings provide more clarity about the role COVID-19 plays in causing stroke in a diverse population of the United States.
ROCHESTER, Minn. -- Bacteriophages, or phages, may play a significant role in treating complex bacterial infections in prosthetic joints, according to new Mayo Clinic research. The findings suggest phage therapy could provide a potential treatment for managing such infections, including those involving antibiotic-resistant microbes.
The research is published in the July issue of Clinical Infectious Diseases (CID).
With an alarm code, we can enter a building without bells going off. It turns out that the SARS coronavirus 2 (SARS-CoV-2) has the same advantage entering cells. It possesses the code to waltz right in.
On July 24 in Nature Communications, researchers at The University of Texas Health Science Center at San Antonio (UT Health San Antonio) reported how the coronavirus achieves this.
A collaboration between Monash Health, the Australian Genomics Health Alliance (AGHA) and researchers at the Monash Biomedicine Discovery Institute has led to the discovery of a rare single gene mutation in a patient that eliminates an immune cell population, namely MAIT cells.
Accurate regional carbon budgets are critical for informing land-based mitigation policy and tracking mitigation progress. For nine regions covering the globe, inventory estimates of carbon stock changes were collected and complemented by satellite estimates of biomass changes where inventory data are missing. The net land-atmospheric carbon exchange was then calculated by taking the sum of the carbon stock changes measured by inventories and lateral carbon fluxes from crop and wood trade and riverine carbon export to the ocean.
A new study, which involved participants eating pizza well after feeling 'full' in order to test what immediate effects this had on the body, finds that our metabolism is surprisingly good at coping with over-indulgence.
Science fiction authors foresaw augmented reality video games, the rise of social media and trends of hyper-consumption, and can help predict future consumer patterns.
New research in the Journal of Consumer Culture, by Lancaster University Management School's Dr Mike Ryder, highlights many parallels between the futures created by sci-fi pioneer Frederik Pohl in the 1950s and the modern world.
While the technology for developing artificial intelligence-powered chatbots has existed for some time, a new viewpoint piece in JAMA lays out the clinical, ethical, and legal aspects that must be considered before applying them in healthcare. And while the emergence of COVID-19 and the social distancing that accompanies it has prompted more health systems to explore and apply automated chatbots, the authors still urge caution and thoughtfulness before proceeding.
When NASA's Aqua satellite passed over the North Atlantic Ocean, it gathered water vapor data on Tropical Storm Gonzalo as tropical storm warnings, a tropical storm watch, and hurricane watch were posted.
Boston, MA -- Early and accurate detection is critical for preventing the spread of COVID-19 and providing appropriate care for patients. Nasopharyngeal (NP) swabs, which require inserting a long shaft into the nasal cavity to collect a sample from the back of the nose and throat, are currently the gold standard for collecting a specimen for diagnosis. But the procedure is technically challenging, often uncomfortable for patients and requires personal protective equipment that may be in short supply.
