FAIRFAX, Va. -- Researchers demonstrated the success of a fully implantable wireless medical device, the Stentrode™ brain-computer interface (BCI), designed to allow patients with severe paralysis to resume daily tasks -- including texting, emailing, shopping and banking online -- without the need for open brain surgery. The first-in-human study was published in the Journal of NeuroInterventional Surgery™, the leading international peer-reviewed journal for the clinical field of neurointerventional surgery.
It is a long journey from harvesting in the field to the cooked dish that reaches the dinner table. The food supply chain covers all those processes and the actors involved in satisfying the consumer's needs. To ensure that the chain is successful requires correct administration of the products in the warehouse, inventory, transport management and coordination between warehouses, transport and destination.
Highly efficient synthesis of ammonia under ambient temperatures and pressures has been drawing increasing attention for wide applications of scientists and industries around the world. Developing highly active and selective materials with transformative catalytic performance for ammonia synthesis is still a giant challenge.
Among the African countries, South Africa has significantly high prevalence rate of overweight and obesity, especially, among women, courtesy certain factors such as nutrition transition and socio-demographic factors. Currently, there is little information about the socio-demographic determinants of overweight/obesity, especially in the rural settings.
In the middle of the pandemic this spring, researchers at the Norwegian University of Science and Technology (NTNU) conducted a survey among members of Kondis, a Norwegian fitness training organization.
Since this survey was sent out in the middle of the lockdown in Norway, participants were asked whether they had changed their exercise habits as a result of the COVID-19 pandemic.
The aim of these initial analyses was to map mental health and sleep problems, and to investigate whether changes in exercise habits had consequences for sleep.
Upon a heart infarct or stroke, rapid restoration of blood flow, and oxygen delivery to the hypo perfused regions is of eminent importance to prevent further damage to heart or brain. Arterial diameter is a critical determinant of blood flow conductance. Scientists of the Karlsruhe Institute of Technology (KIT) have now discovered a novel mechanism to structurally increase arterial diameter by selectively increasing the size of arterial endothelial cells, thereby allowing rapid increases in flow.
Researchers from Erasmus University, The Ohio State University, York University, and London Business School published a new paper in the Journal of Marketing that examines the tension between AI's benefits and costs and then offers recommendations to guide managers and scholars investigating these challenges.
The study, forthcoming in the Journal of Marketing, is titled "Consumers and Artificial Intelligence: An Experiential Perspective" and is authored by Stefano Puntoni, Rebecca Walker Reczek, Markus Giesler, and Simona Botti.
CORVALLIS, Ore. - Corals that appear healthy are more prone to getting sick when they're home to too many parasitic bacteria, new research at Oregon State University shows.
Supported by the National Science Foundation, the study, published in Environmental Microbiology, adds fresh insight to the fight to save the Earth's embattled coral reefs, particularly those in the Caribbean.
To build the machinery that enables bacteria to swim, over 50 proteins have to be assembled according to a logic and well-defined order to form the flagellum, the cellular equivalent of an offshore engine of a boat. To be functional, the flagellum is assembled piece by piece, ending with the helix called flagellar filament, composed of six different subunits called flagellins. Microbiologists from the University of Geneva (UNIGE) have demonstrated that adding sugar to the flagellins is crucial for the flagellum's assembly and functionality.
Massive galaxies were already much more mature in the early universe than previously expected. This was shown by an international team of astronomers who studied 118 distant galaxies with the Atacama Large Millimeter/submillimeter Array (ALMA).
Lianhuaqingwen (LHQW) capsule, a herb medicine product, has been clinically proved to be effective in coronavirus disease 2019 (COVID-19) pneumonia treatment. However, human exposure to LHQW components and their pharmacological effects remain largely unknown. The authors of this study aimed to determine human exposure to LHQW components. Based on the human exposure analysis, several ACE2 binding components with good enzyme inhibitory effects were screened out by ACE2 biochromatography.
COLUMBUS, Ohio - New research shows that when vampire bats feel sick, they socially distance themselves from groupmates in their roost - no public health guidance required.
The researchers gave wild vampire bats a substance that activated their immune system and made them feel sick for several hours, and then returned the bats to their roost. A control group of bats received a placebo.
Data on the behavior of these bats was transmitted to scientists by custom-made "backpack" computers that were glued to the animals' backs, recording the vampire bats' social encounters.
CHAPEL HILL, NC - MicroRNAs (miRNAs) are evolutionarily conserved small noncoding RNAs - bits of genetic code that serve as critical gene regulators in many aspects of biological processes important for human health. Due to their essential roles in gene regulation, miRNAs are tightly regulated, and abnormal miRNA expressions have been linked to cancer, neurological disorders, cardiovascular diseases, and other diseases.
CLEVELAND - An international team of researchers led by Cleveland Clinic's Lerner Research Institute has performed for the first time a wide-scale characterization of missense variants from 1,330 disease-associated genes. Published in Proceedings of the National Academy of Sciences, the study identifies features associated with pathogenic and benign variants that reveal the effects of the mutations at a molecular level.
An environmentally friendly and sustainable synthesis of "heavyweight" polymers with very narrow molecular weight distributions is an important concept in modern polymer chemistry. Thanks to a new photoenzymatic process, Chinese researchers have been able to increase the range of possible monomers. As reported in the journal Angewandte Chemie, the researchers were able to obtain well-defined linear and star-shaped polymers with ultrahigh molecular weights.
