Scientists working at the Department for Functional Nanomaterials at the Institute of Nuclear Physics of the Polish Academy of Sciences designed and synthesized a functional ternary Pt/Re/SnO2/C catalyst as an anode material in a direct ethanol fuel cell. It was possible by synthesizing platinum, rhenium and tin oxide nanoparticles of a spherical shape and ensuring physical contact between them. This finding will lead to the production of more efficient, greener and cheaper fuel cell catalysts.
Long-tailed tits actively avoid harmful inbreeding by discriminating between the calls of close family members and non-family members, according to new research from the University of Sheffield.
Inbred animals typically suffer from reduced survival and reproductive success, so incest is usually avoided. But, in species where young stay close to where they were born, relatives are often encountered as potential mates, increasing the risk of harmful inbreeding.
Ultrasound imaging is one of the workhorses in a modern hospital. It hits the trifecta of being relatively cheap, portable, and non-invasive. The ability to cause future parents to get a bit emotional over fetus images is also an appreciated perk. But ultrasound imaging does have its limitations. Its resolution is often limited by the acoustic wavelength, which is rather long, compared to optical wavelengths.
NEW YORK, NY (June 23, 2020) -- During the height of the COVID-19 pandemic in New York City, health care workers on the front lines had high levels of acute stress, anxiety, and depression, a study by researchers at Columbia University Irving Medical Center and NewYork-Presbyterian has found.
Levels of stress, anxiety and depression were particularly high among those with the greatest amount of patient contact and interaction.
Among the findings:
More than half had high levels of acute stress.
Nearly half screened positive for depressive symptoms.
A team of scientists working at Lawrence Berkeley National Laboratory (Berkeley Lab) has discovered a new form of the human-made element mendelevium. The newly created isotope, mendelevium-244, is the 17th and lightest form of mendelevium, which is element 101 on the periodic table.
Sea ice across the Southern Ocean played a crucial role in controlling atmospheric carbon dioxide levels during times of past climate change - and it could provide a critical resource to improve Earth system models, a new study shows.
The paper by scientists from UNSW and Keele University was published today in Nature Geoscience.
Replacing the expensive metals that break down exhaust gases in catalytic converters with cheaper, more effective materials is a top priority for scientists, for both economic and environmental reasons. Catalysts are required to perform chemical reactions that would otherwise not happen, such as converting polluting gases from automotive exhaust into clean compounds that can be released into the environment. To improve them, researchers need a deeper understanding of exactly how they catalysts work.
The 2016 U.S. presidential election is considered a "game changer" for journalists covering the U.S. presidential elections by causing them to dramatically reconsider how they view their role -- either as neutral disseminators of information or impassioned advocates for the truth -- according to researchers at the University of Missouri's School of Journalism.
Researchers from Sechenov University and the University of Pittsburgh compared the properties of two groups of extracellular vesicles. Either present in a liquid phase or attached to the fibres of the extracellular matrix, these vesicles facilitate metabolism and cell-cell communication. A better understanding of their structure, production and movement can help create new bioengineered materials and repair damaged tissues more quickly. Findings are published in Science Advances.
Researchers at the Department of Infection and Immunity of the Luxembourg Institute of Health (LIH) developed LIH383, a novel molecule that binds to and blocks a previously unknown opioid receptor in the brain, thereby modulating the levels of opioid peptides produced in the central nervous system (CNS) and potentiating their natural painkilling and antidepressant properties.
Researchers at Japan Advanced Institute of Science and Technology (JAIST) and Dalian Institute of Chemical Physics, Chinese Academy of Sciences have successfully established a universal synthetic design using porous organic polymers (POPs) for fuel cell electrolyte, according to an Editor's choice hot article published in the journal Materials Chemistry Frontiers.
As humanity expands its horizons beyond the Earth and begins to consider space missions with extended duration, sustainability necessitates the launch of more space vehicles, increasing the risk of collision with existing space debris. One method of clearing this debris involves a tug vehicle dragging it to a safe region. In a new paper published in EPJ Special Topics, authors Antônio Delson Conceição de Jesus and Gabriel Luiz F.
An article published in the journal Global Ecology and Conservation presents a new five-step protocol to mitigate the mortality of birds of prey due to accidents with infrastructures (power lines, ponds, etc.) and other unnatural causes (direct hunting). The protocol that could also be applied to the conservation of other terrestrial vertebrates -even marine species-is a new scientific contribution from the Conservation Biology Group , led by the lecturer Joan Real, from the Faculty of Biology and the Biodiversity Research Institute (IRBio) of the University of Barcelona.
More than 8 in 10 Americans (83%) say the future of our nation is a significant source of stress, according to the American Psychological Association's most recent survey report, Stress in AmericaTM 2020: Stress in The Time of COVID-19, Volume Two. The previous high was 69%, reported in 2018 as part of APA's annual Stress in America survey.
