In nuclear physics so-called magic number are such nuclear proton and/or neutron numbers, for which the nucleus is more stable compared to neighboring isotopes on the nuclear chart. Researchers in both experimental and theoretical nuclear physics from University of Jyväskylä, Finland, took part of international research team, which studied the nuclear charge radii of potassium isotopes. Isotopes were studied by using the collinear resonance ionization spectroscopy technique.
Lead halide perovskites, with high refractive index and excellent optoelectronic property, have been used in both constructing high-quality optical resonators/lasers and fabricating high-efficiency light-emitting devices for advanced displays. Lenticular printing provides an illusion of depth and shows varying images upon view angles, which is considered as a promising approach towards future stereoscopic displays. To realize lenticular-printing-based display, it is required to modulate the outcoupling direction of emission light rather than that of incident light.
Researchers from the University of Ottawa have discovered that plants may be able to control the genetics of their intimate root symbionts - the organism with which they live in symbiosis - thereby providing a better understanding of their growth.
In addition to having a significant impact on all terrestrial ecosystems, their discovery may lead to improved eco-friendly agricultural applications.
LA JOLLA, CA--As the opioid epidemic raged on with an even greater force during COVID-19, the Scripps Research laboratory of chemist Kim Janda, PhD, has been working on new therapeutic interventions that may be able to prevent the bulk of deaths from opioid overdose.
Janda and his team have developed experimental vaccines that have shown in rodents to blunt the deadly effects of fentanyl--which has been driving the boom in opioid deaths--as well as its even more fatal cousin, carfentanil, a growing source of overdoses and a chemical terrorist threat.
Army scientists evaluated three nonhuman primate species as potential models of SARS-CoV-2 airborne infection, according to results published online this week in PLOS ONE. Their work demonstrates that any of these species may be useful for testing vaccines and therapies in response to the COVID-19 pandemic, which has resulted in over 104 million cases and more than 2 million deaths worldwide in the past year.
Politicians around the world must be held to account for mishandling the covid-19 pandemic, argues a senior editor at The BMJ today.
Executive editor, Dr Kamran Abbasi, argues that at the very least, covid-19 might be classified as 'social murder' that requires redress.
Today 'social murder' may describe a lack of political attention to the conditions in which people are born, grow, live, work and age that exacerbate the pandemic.
A new study further highlighting a potential physiological cause of clinical depression could guide future treatment options for this serious mental health disorder. Published in Frontiers in Psychiatry, researchers show differences between the cellular composition of the brain in depressed adults who died by suicide and non-psychiatric individuals who died suddenly by other means.
Researchers from University of Notre Dame, York University (Canada), and University of New England (Australia) published a new paper in the Journal of Marketing that identifies a novel reason why people under-save and demonstrates a simple, short, and inexpensive intervention that increases intentions to save and actual savings.
CAMBRIDGE, MA -- Twenty years ago this month, the first draft of the human genome was publicly released. One of the major surprises that came from that project was the revelation that only 1.5 percent of the human genome consists of protein-coding genes.
Over the past two decades, it has become apparent that those noncoding stretches of DNA, originally thought to be "junk DNA," play critical roles in development and gene regulation. In a new study published today, a team of researchers from MIT has published the most comprehensive map yet of this noncoding DNA.
A new technique has taken the first images of muon particle beams. Nagoya University scientists designed the imaging technique with colleagues in Osaka University and KEK, Japan and describe it in the journal Scientific Reports. They plan to use it to assess the quality of these beams, which are being used more and more in advanced imaging applications.
After the Chernobyl disaster of 1986, the 2011 Fukushima Daiichi nuclear power plant (FDNPP) disaster was the second worst nuclear incident in history. Its consequences were tremendous for the Japanese people and now, almost a decade later, they can still be felt both there and in the rest of the world. One of the main consequences of the event is the release of large amounts of cesium-137 (137Cs)--a radioactive "isotope" of cesium--into the atmosphere, which spread farther away from the power plant through wind and rainfall.
Tampa, FL (Feb. 3, 2021) -- A preclinical study by a University of South Florida Health (USF Health) Morsani College of Medicine research team has discovered a new mechanism for how Zika virus can pass from mothers to their children during pregnancy - a process known as vertical transmission.
The SARS-CoV-2, the new coronavirus behind the current pandemic, infects humans by binding its surface-exposed spike proteins to ACE2 receptors exposed on the cell membranes.
Upon a vaccination or a real infection, it takes several weeks before the immunity develops antibodies that can selectively bind to these spike proteins. Such antibody-labeled viruses are neutralized by the natural killer and T cells operated by the human immunity.
A higher diversity of flowering plants increases the breeding success of wild bees and may help compensate for the negative effects of insecticides. This is what researchers from the Universities of Göttingen and Hohenheim, as well as the Julius Kühn Institute, have found in a large-scale experimental study. The results have been published in the scientific journal Ecology Letters.
Researchers in Costa Rica have found that some bacteria on the skin of amphibians prevent growth of the fungus responsible for what has been dubbed 'the amphibian apocalypse'.
Published in the journal Microbiology, the research identified a number of bacteria which could growth of the fungus Batrachochytrium dendrobatidis (Bd). One particularly dangerous strain of the fungus, called BdGPL-2, is responsible for mass amphibian die-offs around the world.
