Tsukuba, Japan—For realizing carbon neutrality, the demand for the development of direct methanol/formic acid-fuel cell technology has been increasing. In this technology, methanol or formic acid is used as an e-fuel for generating electricity. The fuel cells generate electricity via proton transfer; however, conventional proton-exchange membranes suffer from the "crossover phenomenon," where the fuel molecules are also transferred between anodes and cathodes. Thereafter, the fuel molecules are unnecessarily oxidized and the electrodes are deactivated. In this study, the researchers developed a new proton-exchange ...

Tsukuba, Japan—The search for functional natural compounds that can improve age-related cognitive decline has recently emerged as an important research focus to promote healthy aging. Trigonelline (TG), a plant alkaloid found in coffee, as well as in fenugreek seed and radish, was anticipated to possess cognitive enhancement properties. In this study, researchers led by the University of Tsukuba investigated the effects of TG on memory and spatial learning (acquiring, retaining, structuring, and applying information related to the surrounding physical environment) from both a cognitive and molecular biology perspective ...

Tsukuba, Japan—In eukaryotes, genomic DNA, which is a very long double helix containing all the genetic information, wraps around a globular protein called a histone and folds it many times before being contained within the nucleus. Various post-translational modifications (for example, addition of chemical groups) occur on histones. Among them, the methylation of residues of lysine, which is one of the amino acids that make up histones, regulates the folding of genomic DNA and acts as a switch to turn gene transcription on and off. The research group has discovered the methylation of histidine residues as a new post-translational ...

This study is led by Dr Cheng-Guo Duan (Center of Excellence in Molecular Plant Sciences, Chinese Academy of Science). As a conserved epigenetic mark, DNA cytosine methylation at 5’ position (5-mC) plays important roles in multiple biological processes including plant immunity. While, it remains still elusive about the involvement of DNA methylation in the determinants of virulence of phytopathogenic fungi. Verticillium dahliae, one of the major causal pathogens of Verticillium wilt disease that causes great losses in many crops, has a wide host range. Due to the lack of natural disease-resistant ...

Artifical intelligence not only affords impressive performance, but also creates significant demand for energy. The more demanding the tasks for which it is trained, the more energy it consumes. Víctor López-Pastor and Florian Marquardt, two scientists at the Max Planck Institute for the Science of Light in Erlangen, Germany, present a method by which artificial intelligence could be trained much more efficiently. Their approach relies on physical processes instead of ...

DURHAM, N.C. – Maintaining a water level between 20 and 30 centimeters below the local water table will boost southern peatlands’ carbon storage and reduce the amount of climate-warming carbon dioxide (CO2) and methane they release back into the atmosphere during dry periods by up to 90%, a new Duke University study finds. “We could immediately reduce U.S. carbon losses by 2% to 3% of our total national goal by applying this guideline on about 100,000 acres of restored or partially restored peatlands currently found across ...

A research team, led by Professor Jong-Beom Baek and his team in the School of Energy and Chemical Engineering at UNIST have achieved a significant breakthrough in battery technology. They have developed an innovative method that enables the safe synthesis of fluorinated carbon materials (FCMs) using polytetrafluoroethylene (PTFE) and graphite. Fluorinated carbon materials have garnered considerable attention due to their exceptional stability, attributed to the strong C-F bonding—the strongest among carbon single bonds. However, traditional methods of fluorination involve highly toxic reagents such as hydrofluoric acid (HF), making them unsuitable for practical ...

As energy demand continues to rise, research into new, efficient renewable and clean energy sources is an urgent priority. Currently, renewable energy sources like solar, wind, tide, and geothermal make up less than 40% of the current energy demand. Increasing this percentage and reducing the amount of fossil fuels used will require other, more efficient renewable and clean energy sources. Hydrogen is a promising alternative, but it is currently produced using steam reforming, which is inefficient and produces CO2 emissions. Electrochemical water splitting, also called ...

BOSTON – There is growing evidence that a relative abundance of certain gut microbes may be related to skeletal health, according to a new study published in Frontiers in Endocrinology. If confirmed by additional research, the findings could provide the opportunity to alter gut microbiomes to achieve better bone health, as scientists learn more about “osteomicrobiology,” a new term recently used to characterize this relationship.   Due to the lack of large-scale human studies of the gut microbiome and skeletal health, researchers led by Paul C. Okoro, Data Scientist II at Hebrew SeniorLife and Hinda and Arthur Marcus Institute for ...

Primate species with better colour vision are not more likely to have red skin or fur colouration, as previously thought. The findings, published this week in the Biological Journal of the Linnean Society, suggest that red skin and/or red-orange fur may be beneficial for use in social communication even in primate species that don't have particularly good colour vision. It's long been assumed that primates' colourful skin and fur is linked to their enhanced colour vision,  and the results may have implications for understanding why these traits exist in different species. Lead author Robert MacDonald from the University of Bristol explained: ...

Puberty in both girls and boys with type 1 diabetes has shifted forward over the last two decades, according to research presented at the 61st Annual European Society for Paediatric Endocrinology Meeting in The Hague. Additionally longer duration of diabetes, bigger waistlines, and lower blood sugar levels were associated with even earlier puberty onset. The findings of this large-scale study highlight a close relationship between type 1 diabetes and puberty onset and the utmost importance of managing diabetes and weight ...

Children exposed to higher levels of synthetic chemicals in everyday products, such as water-resistant clothes, umbrellas and food packaging, are more likely to mature later during puberty, according to research presented at the 61st Annual European Society for Paediatric Endocrinology Meeting in The Hague. The findings may help better regulate the industrial production and use of these chemicals on a national and international level. Perfluoroalkyl and polyfluoroalkyl substances (PFAS), also known ...

Oak Ridge National Laboratory researchers have conducted a comprehensive life cycle, cost and carbon emissions analysis on 3D-printed molds for precast concrete and determined the method is economically beneficial compared to conventional wood molds. Precast concrete is used in building construction and produced by pouring the material into a reusable mold. For decades, these molds have been made from wood — a technique that requires a highly specialized skillset. As an alternative, molds made from fiber-reinforced polymer composites can be 3D printed. “We developed a techno-economic model that compared costs associated with each method, evaluating materials, equipment, ...

Artisanal and small-scale gold mining is a lifeline for many who live in Madre de Dios, a region in southeastern Peru, where poverty is high and jobs are scarce. But the economic development in this part of the Amazon basin comes at a cost, as it causes deforestation, build up of sediment in rivers, and mercury contamination in nearby watersheds, threatening public health, Indigenous peoples, and the future of the biodiversity hotspot. And much of the mining activity is unauthorized. Seeking to eliminate illegal artisanal and small-scale gold mining activity and its many negative impacts, the Peruvian government deployed “Operation Mercury” (Operation Mercurio) in February ...
