Russian researchers have proposed a new method for synthesizing high-quality graphene nanoribbons -- a material with potential for applications in flexible electronics, solar cells, LEDs, lasers, and more. Presented in The Journal of Physical Chemistry C, the original approach to chemical vapor deposition, offers a higher yield at a lower cost, compared with the currently used nanoribbon self-assembly on noble metal substrates. Silicon-based electronics are steadily approaching their limits, and one wonders which material could give our devices the next big push. Graphene, the 2D sheet of carbon atoms, comes to mind but for all its celebrated electronic properties, it does not have what it takes: Unlike silicon, graphene does not have the ability to switch between ...

CHICAGO (January 11, 2021): A new study of liver transplant centers confirms that non-Hispanic white patients get placed on liver transplant waitlists at disproportionately higher rates than non-Hispanic Black patients. However, researchers went a step further as they identified key reasons for that disparity: disproportionate access to private health insurance, travel distance to transplant centers, and a potential lack of knowledge among both practitioners and patients about available options. The study was selected for the 2020 Southern Surgical Association Program and published as an "article in press" on the website of the Journal of the American College of Surgeons in advance of print. "We found that the Black population was underrepresented at the vast majority of centers, ...

All-solid-state batteries are the next-generation batteries that can simultaneously improve the stability and capacity of existing lithium batteries. The use of non-flammable solid cathodes and electrolytes in such batteries considerably reduces the risk of exploding or catching fire under high temperatures or external impact and facilitates high energy density, which is twice that of lithium batteries. All-solid-state batteries are expected to become a game changer in the electric vehicle and energy storage device markets. Despite these advantages, the low ionic conductivity of solid electrolytes combined with their high interfacial resistance and rapid deterioration reduce battery performance and life, thus limiting their commercialization. The ...

"The findings provide an increased understanding of how the virus gets through the stomach and intestinal system. Continued research can provide answers to whether this property can also be used to create vaccines that ride 'free rides' and thus be given in edible form instead of as syringes," says Lars-Anders Carlson, researcher at Umeå University. The virus that the researchers have studied is a so-called enteric adenovirus. It has recently been clarified that enteric adenoviruses are one of the most important factors behind diarrhea among infants, and they are estimated to kill more than 50,000 children under the age of five each year, ...

Researchers from Trinity College Dublin have discovered a key mechanism underlying bacterial skin colonisation in atopic dermatitis, which affects millions around the globe. Atopic dermatitis (AD, also called commonly eczema) is the most common chronic inflammatory skin disorder in children, affecting 15-20% of people in childhood. During disease flares, patients experience painful inflamed skin lesions accompanied by intense itch and recurrent skin infection. The bacterium Staphylococcus aureus (S. aureus) thrives on skin affected by AD, increasing inflammation and worsening AD symptoms. Although a small number of therapies are available at present for patients with moderate ...

The findings have been used by the Dental Schools' Council, Association of Dental Hospitals and the Scottish Dental Clinical Effectiveness ...

Micro-CT scanning and digital reconstructions have been used to compare the skulls of the Tasmanian tiger (thylacine) and wolf across their early development and into adulthood, establishing that not only did the thylacine resemble the wolf as adults, but also as newborns and juveniles. "Remarkably, the Tasmanian tiger pups were more similar to wolf pups than to other closely related marsupials," Professor Andrew Pask from the University of Melbourne said. The collaborative study with Flinders University and Museums Victoria complement earlier findings that thylacine and wolf have evolved ...

Artificial intelligence and machine learning are already an integral part of our everyday lives online. For example, search engines such as Google use intelligent ranking algorithms and video streaming services such as Netflix use machine learning to personalize movie recommendations. As the demands for AI online continue to grow, so does the need to speed up AI performance and find ways to reduce its energy consumption. Now a University of Washington-led team has come up with a system that could help: an optical computing core prototype that uses phase-change material.

Delivery of genetic molecules such as mRNA into cells is vital with important applications such as vaccine development. Various agents have been developed for mRNA delivery. However, conventional mRNA nanocarriers mainly focus on their physical interaction with mRNA molecules, or protection / delivery of mRNA, such as adjusting physical properties of nanocarriers to control binding with mRNA or cellular uptake. Moreover, effective mRNA delivery in hard-to-transfect APCs remains a challenge. The hard-to-transfect nature in APCs is partly attributed to the suppressed mRNA translation associated with the intrinsic high intracellular glutathione (GSH) level. Thus, ...

Photorespiration is a highly energy consuming process in plants that leads to the release of previously fixed CO2. Thus, engineering this metabolic process is a key approach for improvement of crop yield and for meeting the challenge of ever-rising CO2 levels in the atmosphere. Researchers led by Tobias Erb from the Max Planck Institute for Terrestrial Microbiology in Marburg, Germany, have now succeeded in engineering the TaCo pathway, a synthetic photorespiratory bypass. This new-to-nature metabolic connection opens up new possibilities of CO2 fixation ...

With the rapid development of smart portable electronics and electric vehicles, the consumption of lithium resource will increase dramatically and the cost of lithium-ion batteries (LIBs) may increase significantly in the future. In addition, the shortage (0.0017 wt% in the earth's crust) and uneven crustal distribution of lithium also limit its further development and application. As potassium (2.7 wt% in the earth's crust) have properties similar to lithium and abundant reserves. Therefore, as an alternative to LIBs, potassium ion batteries (PIBs) have become the focus of research. Potassium (2.92 V vs. ...

Scientists from the Max Planck Institute of Psychiatry, led by Nikolaos Koutsouleris, combined psychiatric assessments with machine-learning models that analyse clinical and biological data. Although psychiatrists make very accurate predictions about positive disease outcomes, they might underestimate the frequency of adverse cases that lead to relapses. The algorithmic pattern recognition helps physicians to better predict the course of disease. The results of the study show that it is the combination of artificial and human intelligence that optimizes the prediction ...

The spiky structure that erupts from the smooth surface of a ferrofluid when a magnet is brought close can be predicted more accurately than previously thought. KAUST researchers have shown that computational algorithms can calculate the ferrofluid's bristling response to a magnet by simulating only the liquid's surface layer. Ferrofluids are liquid suspensions of iron-based particles that behave like a regular fluid, but once a magnet is present, the ferrofluid rapidly shape-shifts to form spikes that align with the magnetic field. Originally developed by NASA, ferrofluids have numerous uses ranging from advanced electronics to nanomedicine and have the potential for even broader use, if their magnetic responses could be predicted more accurately. Dominik Michels and ...

Most people with opioid use disorder who would benefit from medication do not receive it. Buprenorphine is a safe and effective ...

DALLAS - Jan. 11, 2021 - A set of biomarkers not traditionally associated with cell fate can accurately predict how genetically identical cells behave differently under stress, according to a UT Southwestern study. The findings, published by Cell Reports as a Dec. 1 cover story, could eventually lead to more predictable responses to pharmaceutical treatments. Groups of the same types of cells exposed to the same stimuli often display different responses. Some of these responses have been linked to slight differences in genetics between individual cells. However, even genetically identical cells can diverge in ...

As the planet continues to warm, the twin challenges of diminishing water supply and growing energy demand are intensifying. But because water and energy are inextricably linked, as we try to adapt to one challenge - say, by getting more water via desalination or water recycling - we may be worsening the other challenge by choosing energy-intensive processes. So, in adapting to the consequences of climate change, how can we be sure that we aren't making problems worse? Now, researchers at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab), UC Berkeley, and UC Santa Barbara have developed a science-based analytic framework to evaluate such complex connections between water and energy, and options for adaptations in response to an evolving ...

CORVALLIS, Ore. - Researchers in the Oregon State University College of Engineering have developed a battery anode based on a new nanostructured alloy that could revolutionize the way energy storage devices are designed and manufactured. The zinc- and manganese-based alloy further opens the door to replacing solvents commonly used in battery electrolytes with something much safer and inexpensive, as well as abundant: seawater. Findings were published today in Nature Communications. "The world's energy needs are increasing, but the development of next-generation electrochemical energy storage systems with high energy density and long cycling life ...

PULLMAN, Wash. - Biomarkers in human sperm have been identified that can indicate a propensity to father children with autism spectrum disorder. These biomarkers are epigenetic, meaning they involve changes to molecular factors that regulate genome activity such as gene expression independent of DNA sequence, and can be passed down to future generations. In a study published in the journal Clinical Epigenetics on Jan. 7, researchers identified a set of genomic features, called DNA methylation regions, in sperm samples from men who were known to have autistic children. Then in a set of blind tests, the researchers were able to use the presence of these features to determine whether other men had fathered autistic children with 90% ...
