UNIVERSITY PARK, Pa. — Experiencing traumatic events such as natural disasters may have long-term consequences for the academic progress and future food security of youth — a problem researchers said could worsen with the increased frequency of extreme weather events due to climate change. In a study using data from Peru, researchers from Penn State’s College of Agricultural Sciences found that being exposed to a greater number of traumatic events or “shocks,” such as a natural disaster or loss of family income, in early ...

Researchers have demonstrated a new material for single-molecule electronic switches, which can effectively vary current at the nanoscale in response to external stimuli. The material for this molecular switch has a unique structure created by locking a linear molecular backbone into a ladder-type structure. A new study finds that the ladder-type molecular structure greatly enhances the stability of the material, making it highly promising for use in single-molecule electronics applications. Reported in the journal Chem, the study shows that the ladder-type molecule serves as a robust and reversible molecular switch over a wide range of conductivity levels and different molecular ...

A $7 million study beginning this summer at Wake Forest University and Wake Forest University School of Medicine will help determine whether a combination of resistance training plus bone-strengthening exercises and/or osteoporosis medication use can help older adults safely lose weight without sacrificing bone mass. That paradox – that shedding pounds can help stave off heart disease and diabetes while increasing bone loss and subsequent fracture risk – has been a focus of Wake Forest researcher Kristen Beavers for about a decade.  Her previous research ...

Insights into healing and aging were discovered by National Institutes of Health researchers and their collaborators, who studied how a tiny sea creature regenerates an entire new body from only its mouth. The researchers sequenced RNA from Hydractinia symbiolongicarpus, a small, tube-shaped animal that lives on the shells of hermit crabs. Just as the Hydractinia were beginning to regenerate new bodies, the researchers detected a molecular signature associated with the biological process of aging, also known as senescence. According to the study published in Cell Reports, Hydractinia demonstrates that the fundamental biological processes of healing and aging are intertwined, ...

15N isotope-labeled amino acids (15N-amino acids) provide a safe and effective tracer tool for studying the synthesis of natural products, protein metabolism, and disease diagnosis and treatment in living organisms. In addition, it is an important synthetic block for the synthesis of 15N-labeled drugs. Currently, 15N-labeled amino acids are generally synthesized by microbial fermentation and chemical reduction amination of ketoacids, but these methods usually require complex steps, high temperature conditions or the use of toxic cyanide, causing energy and environmental ...

Subtropical mode water (STMW) is a vertically homogeneous thermocline water mass, serving as heat, carbon, and oxygen silos in the ocean interior and providing memory of climate variability for climate prediction. Understanding physics governing STMW formation is thus of broad scientific significance and has received much attention. Traditionally, it has been considered that STMW is constructed by basin-scale atmospheric forcing. Due to the limitations resulting from sparse sampling of observations and coarse ...

Multiple sclerosis (MS) is a serious neurological disease that usually causes permanent disability. Approximately 2.9 million people are affected worldwide, 240,000 in Germany alone. The exact cause of the disease is not yet clear, but a central feature is a loss of the insulating protective layer of axons – the neuronal connections in the central nervous system – which is triggered by autoimmune processes. The coating of the axons, known as myelin, is formed by highly specialised glial cells (i.e. oligodendrocytes) and enables the rapid transmission ...

Co-design, that is, designing software and hardware simultaneously, is one way of attempting to meet the computing-power needs of today’s artificial intelligence applications. Compilers, which translate instructions from one representation to another, are a key piece of the puzzle. A group of researchers at the Chinese Academy of Sciences summarized existing compiler technologies in deep learning co-design and proposed their own framework, the Buddy Compiler. The group’s review paper was published June 19 in Intelligent Computing, a Science Partner Journal. Although others have summarized optimizations, hardware architectures, co-design approaches, and compilation ...
