Efficient training for artificial intelligence

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 ...

Re-wetting is key for boosting CO2 storage in southern peatlands

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 ...

New study unveils direct synthesis of FCMs via solid-state mechanochemical reaction between graphite and PTFE

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 ...

Gold nanoclusters can improve electrochemical water splitting to produce hydrogen

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 ...

Study finds connection between gut microbiome and bone density

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 ...

One-stop implementation from signal detection to processing

In order to explore brain disorders and discover potential treatments, it is crucial to analyze and interpret the signals transmitted by the brain.  Although neural probes attached to the brain can effectively detect subtle bio- signals, they lack the ability to amplify and process these signals, necessitating the use of a separate amplifier. The research team identified a solution in common household “inkjet printers” that have been widely available for a long time.   A collaborative research team led by Professor Sungjune Jung (Department of Materials Science and Engineering, Department of Convergence IT Engineering) with PhD candidate ...

Newer diabetes treatments are understudied in Black populations and may be less beneficial

New research analysing the effects of two drugs used to treat type 2 diabetes indicates a consistent lack of cardiovascular and renal benefits in Black populations. Cardiovascular disease is the leading cause of severe illness and death associated with type 2 diabetes. Renal disease is also a common complication of type 2 diabetes. The drugs, called sodium-glucose co-transporter 2 inhibitors (SGLT2-Is) and glucogen-like peptide 1 receptor agonists (GLP1-RAs), are some of the newer treatments prescribed to lower blood sugar levels in people with type 2 diabetes. The research findings, published in the Journal of the ...

Colorful primates don’t have better color vision, study finds

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: ...

Benefit breakdown, 3D printed vs. wood molds

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, ...

Peru’s Operation Mercury stopped most illegal gold mining in one biodiversity hotspot in the Amazon. Then the COVID-19 pandemic hit.

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 ...

Scientists reveal intricate mechanisms cells use to build protein destruction signals

Within the intricate molecular landscape inside of a cell, the orchestration of proteins demands precise control to avoid disease. While some proteins must be synthesised at specific times, others require timely breakdown and recycling. Protein degradation is a fundamental process that influences cellular activities such as the cell cycle, cell death, or immune response. At the core of this process lies the proteasome, a recycling hub in the cell. The proteasome degrades proteins if they carry a molecular tag formed by a chain of ubiquitin molecules. The task of attaching this tag falls to enzymes known as ubiquitin ligases. This process, known ...
