What The Study Did: Researchers looked at whether age-related hearing impairment among older adults is associated with poorer and faster decline in physical function and reduced walking endurance.
A new University of Liverpool study could help scientists mitigate the future spread of zoonotic and livestock diseases caused by existing viruses.Researchers have used a form or artificial intelligence (AI) called machine-learning to predict more than 20,000 unknown associations between known viruses and susceptible mammalian species. The findings, which are published in Nature Communications, could be used to help target disease surveillance programmes.
Researchers have created the first CRISPR-Cas9-based gene drive designed for plants. The new technology, which allows scientists to cut and copy key genetic elements, helps scientists breed plants that defend against crop diseases and withstand the impacts of climate change.
Researchers from University of Tsukuba have found that the share of calls to after-hours house call medical services for fever or cold symptoms decreased during the COVID-19 pandemic in Tokyo, but that the severity of symptoms in those patients was significantly increased. Use of such services could reduce the burden on hospitals and early detection could improve patient outcomes if hesitancy to seek treatment in a pandemic can be addressed.
Perovskite colloidal quantum dots (Pe-CQDs) are highly promising nanocrystals for optoelectronic applications. However, the size of the crystals should ideally be equal to ensure a consistent energy landscape. In a recent study, scientists clarified the relationship between differences in particle size -- polydispersity -- and the optoelectronic characteristics of Pe-CQDs. They showed that using equally sized, or 'monodisperse,' quantum dots results in markedly better performance in Pe-CQD solar cells... Читать дальше...
The contemporary materials industry raises the problem of creating a microscopic theory that allows to describe the observed physicochemical properties of a wide class of substances which are in demand in modern industry, medicine, and agriculture.
Recently, a Korean research team has drawn attention for developing a technology to reduce the adverse effects by accumulating the peripheral substances of cells on the surfaces of the materials. The Korea Institute of Science and Technology (KIST) has released an announcement that the research team of Dr. Yoon Ki Joung, from the Center for Biomaterials, has successfully developed a material that can be used to accumulate substances present at the cell periphery on the surface of implantable medical materials.
Curtin University research has found tiny amounts of gold can be trapped inside pyrite, commonly known as 'fool's gold,' which would make it much more valuable than its name suggests.
Researchers at Arizona State University are using bioengineering to trigger and control cell differentiation and transition is expand possibilities for diagnostics, vaccine development and therapeutic treatments.
University of Tsukuba researchers used time-resolved photoelectron emission microscopy (TR-PEEM) to probe the exciton dynamics of thermally activated delayed fluorescence organic light-emitting diodes (TADF-OLEDs). TADF-OLEDs based on solid-state substrates have significant potential for use in display technology owing to their high efficiency; however, their electron dynamics are not well understood. The TR-PEEM method showed electron accumulation that indicated exciton dissociation. It is hoped... Читать дальше...
Researchers from Tokyo Medical and Dental University (TMDU) have demonstrated direct homophilic interaction of lysosomal-associated membrane protein 2 (LAMP2). They found that the two-domain architecture of LAMP-2 underlies its proper arrangement and function.
Chemists at Scripps Research have solved a long-standing problem in their field by developing a method for making a highly useful and previously very challenging type of modification to organic molecules.
James Cook University scientists in Australia believe they have made a breakthrough in the science of keeping premature babies alive.
Rising greenhouse gases and declining aerosols have triggered an approximate four-day delay in rainfall over tropical land and the Sahel.
Babies are generally poorer at seeing and recognizing objects than adults because of their immature visual abilities. However, a study published in the journal Proceedings of the National Academy of Sciences (PNAS) on June 23, 2021 reported that, in some circumstances, infants younger than 7 months old can perceive objects that older infants and adults cannot. This surprising result demonstrates the distinct mechanisms of visual perception between young infants and adults.
In 2021 Acta Pharmaceutica Sinica B (APSB) is celebrating its 10th anniversary. The journal was founded with the goal of creating a global high-level forum centred around drug discovery and pharmaceutical research/application. APSB was included by Chemical Abstracts in 2011, accepted by PubMed Central in 2015, indexed by Science Citation Index in 2017 and has evolved to become one of the most important international journals in the field of pharmaceutical sciences.
Scientists of Tomsk Polytechnic University jointly with their colleagues have synthetized a unique molecule of verdazyl-nitronyl nitroxide triradical. Only several research teams in the world were able to obtain molecules with similar properties. The molecule is stable. It is able to withstand high temperatures and obtains promising magnetic properties. It is a continuation of scientists' work on the search for promising organic magnetic materials. The research findings are published in the Journal of the American Chemical Society (IF... Читать дальше...
For the first, time UNC School of Medicine scientist Katie Baldwin, Ph.D., and colleagues revealed a central role of the glial protein hepaCAM in building the brain and affecting brain function early in life.The findings, published in Neuron, have implications for better understanding disorders, such as autism, epilepsy, and schizophrenia, and potentially for creating therapeutics for conditions such as the progressive brain disorder megalencephalic leukoencephalopathy with subcortical cysts (MLC).
In a new article published in The Lancet Public Health, they report results from a first-of-its kind nationwide study evaluating a targeted intervention aimed at transforming dual users' e-cigarettes from a product that might maintain smoking into a tool that can be used to aid smoking cessation.
Researchers discovered that a small subpopulation of antibodies binding to unique sites on each serotype are linked to protection. The research, published in the Journal of Clinical Investigation, provides important information for vaccine developers to consider when creating a dengue vaccine, which has long eluded scientists.
EMBL Hamburg's Wilmanns and Kosinski groups have determined the detailed structure of a bacterial protein complex critical for tuberculosis infection.
Using DNA, scientists organized bioactive proteins in desired 2D and 3D ordered arrays -- promising for structural biology, biomedicine, and more.
Scientists have gained novel insights into how an important class of immune receptors called tumour necrosis factor receptors (TNFR) are activated.
What does it take for people to commit to take action to promote social equality? And how might this differ for people from advantaged and disadvantaged groups?
People with dementia receiving home health care visits are less likely to be readmitted to the hospital when there is consistency in nursing staff, according to a new study by researchers at NYU Rory Meyers College of Nursing.
